GENERAL POWER TOOL SAFETY WARNINGS

Read all safety warnings and all instructions. Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury.
SAVE ALL WARNINGS AND INSTRUCTIONS FOR FUTURE REFERENCE
The term "power tool" in the warnings refers to your mainsoperated (corded) power tool or battery-operated (cordless) power tool.

1. Work Area Safety
   1. Keep work area clean and well lit. Cluttered or dark areas invite accidents.
   2. DO NOT operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.
   3. Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.
2. Electrical Safety
   1. Power tool plugs must match the outlet. Never modify the plug in any way. DO NOT use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce risk of electric shock.
   2. Avoid body contact with earthed or grounded surfaces such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.
   3. DO NOT expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
   4. DO NOT abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock.
   5. When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.
   6. If operating a power tool in a damp location is unavoidable, use a ground fault circuit interrupter (GFCI) protected supply. Use of a GFCI reduces the risk of electric shock.
3. Personal Safety
   1. Stay alert, watch what you are doing and use common sense when operating a power tool. DO NOT use a power tool while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious personal injury.
   2. Use personal protective equipment. Always wear eye protection. Protective equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.
   3. Prevent unintentional starting. Ensure the switch is in the off position before connecting to power source and/or battery pack, picking up or carrying the tool. Carrying power tools with your finger on the switch or energizing power tools that have the switch on invites accidents.
   4. Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personal injury.
   5. DO NOT overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.
   6. Dress properly. DO NOT wear loose clothing or jewelry. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewelry or long hair can be caught in moving parts.
   7. If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Use of dust collection can reduce dust-related hazards.
4. Power Tool Use and Care
   1. DO NOT force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and safer at the rate for which it was designed.
   2. DO NOT use the power tool if the switch does not turn it on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired.
   3. Disconnect the plug from the power source and/ or the battery pack from the power tool before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.
   4. Store idle power tools out of the reach of children and DO NOT allow persons unfamiliar with the power tool or these instructions to operate the power tool. Power tools are dangerous in the hands of untrained users.
   5. Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tool's operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools.
   6. Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
   7. Use the power tool, accessories and tool bits, etc. in accordance with these instructions, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from those intended could result in a hazardous situation.
5. Battery Tool Use and Care
   1. Recharge only with the charger specified by the manufacturer. A charger that is suitable for one type of battery pack may create a risk of fire when used with another battery pack.
   2. Use power tools only with specifically designated battery packs. Use of any other battery packs may create a risk of injury and fire.
   3. When battery pack is not in use, keep it away from other metal objects, like paper clips, coins, keys, nails, screws, or other small metal objects, that can make a connection from one terminal to another. Shorting the battery terminals together may cause burns or a fire.
   4. ) Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact accidentally occurs, flush with water. If liquid contacts eyes, additionally seek medical help. Liquid ejected from the battery may cause irritation or burns.
6. Service
   1. Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained.

Additional Safety Rules for Portable Band Saws

• Hold power tool by insulated gripping surfaces when performing an operation where the cutting accessory may contact hidden wiring. Cutting accessories contacting a "live" wire may make exposed metal parts of the power tool "live" and could give the operator an electric shock.
• Keep hands away from cutting area and blade.
• Always make sure the portable band saw is clean before using.
• Always cease operation at once if you notice any abnormality whatsoever.
• Always be sure all components are mounted properly and securely before using tool.
• Always handle the band saw blade with care when mounting or removing it.
• Always keep your hands out of the line of the band saw blade.
• Always wait until the motor has reached full speed before starting a cut.
• Always keep handles dry, clean, and free of oil and grease.Hold the tool firmly when in use.
• Always be alert at all times, especially during repetitive, monotonous operations. Always be sure of position of your hands relative to the blade.
• Never remove work stop.
• Stay clear of end pieces that may fall after cutting off.They may be hot, sharp and/or heavy. Serious personal injury may result.

Additional Safety Information

ALWAYS use safety glasses. Everyday eyeglasses are NOT safety glasses. Also use face or dust mask if cutting operation is dusty. ALWAYS WEAR CERTIFIED SAFETY EQUIPMENT:

• ANSI Z87.1 eye protection (CAN/CSA Z94.3),
• ANSI S12.6 (S3.19) hearing protection,
• NIOSH/OSHA/MSHA respiratory protection.

Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to the State of California to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are:

• lead from lead-based paints,
• crystalline silica from bricks and cement and other masonry products, and
• arsenic and chromium from chemicallytreated lumber.

Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure to these chemicals: work in a well ventilated area, and work with approved safety equipment, such as those dust masks that are specially designed to filter out microscopic particles.

• Avoid prolonged contact with dust from power sanding, sawing, grinding, drilling, and other construction activities. Wear protective clothing and wash exposed areas with soap and water. Allowing dust to get into your mouth, eyes, or lay on the skin may promote absorption of harmful chemicals.
  
  Use of this tool can generate and/ or disperse dust, which may cause serious and permanent respiratory or other injury. Always use NIOSH/OSHA approved respiratory protection appropriate for the dust exposure. Direct particles away from face and body.
  
  Always wear proper personal hearing protection that conforms to ANSI S12.6 (S3.19) during use. Under some conditions and duration of use, noise from this product may contribute to hearing loss.
  
  When not in use, place tool on its side on a stable surface where it will not cause a tripping or falling hazard. Some tools with large battery packs will stand upright on the battery pack but may be easily knocked over.

• DO NOT charge or use the battery pack in explosive atmospheres, such as in the presence of flammable liquids, gases or dust.Inserting or removing the battery pack from the charger may ignite the dust or fumes.
• NEVER force the battery pack into the charger. DO NOT modify the battery pack in any way to fit into a non-compatible charger as battery pack may rupture causing serious personal injury. Consult the chart at the end of this manual for compatibility of batteries and chargers.
• Charge the battery packs only in designated DeWALT chargers.
• DO NOT splash or immerse in water or other liquids.
• DO NOT store or use the tool and battery pack in locations where the temperature may reach or exceed 104°F (40°C) (such as outside sheds or metal buildings in summer). For best life store battery packs in a cool, dry location.
  NOTE: DO NOT store the battery packs in a tool with the trigger switch locked on. Never tape the trigger switch in the ON position.
• DO NOT incinerate the battery pack even if it is severely damaged or is completely worn out. The battery pack can explode in a fire. Toxic fumes and materials are created when lithium ion battery packs are burned.
• If battery contents come into contact with the skin, immediately wash area with mild soap and water. If battery liquid gets into the eye, rinse water over the open eye for 15 minutes or until irritation ceases. If medical attention is needed, the battery electrolyte is composed of a mixture of liquid organic carbonates and lithium salts.
• Contents of opened battery cells may cause respiratory irritation. Provide fresh air. If symptoms persist, seek medical attention.
  
  Burn hazard. Battery liquid may be flammable if exposed to spark or flame.
  
  Fire hazard. Never attempt to open the battery pack for any reason. If the battery pack case is cracked or damaged, DO NOT insert into the charger. DO NOT crush, drop or damage the battery pack. DO NOT use a battery pack or charger that has received a sharp blow, been dropped, run over or damaged in any way (e.g., pierced with a nail, hit with a hammer, stepped on). Damaged battery packs should be returned to the service center for recycling.

Transportation

Fire hazard. DO NOT store or carry the battery pack so that metal objects can contact exposed battery terminals. For example, DO NOT place the battery pack in aprons, pockets, tool boxes, product kit boxes, drawers, etc., with loose nails, screws, keys, etc. Transporting batteries can possibly cause fires if the battery terminals inadvertently come in contact with conductive materials such as keys, coins, hand tools and the like. The US Department of Transportation Hazardous Material Regulations (HMR) actually prohibit transporting batteries in commerce or on airplanes in carry-on baggage UNLESS they are properly protected from short circuits. So when transporting individual battery packs, make sure that the battery terminals are protected and well insulated from materials that could contact them and cause a short circuit.

Shipping the DeWALT FlEXVOlT™ Battery
The DeWALT FLEXVOLT™ battery has two modes: Use and shipping.
Use Mode: When the FLEXVOLT™ battery stands alone or is in a DeWALT 20V Max* product, it will operate as a 20V Max* battery. When the FLEXVOLT™ battery is in a 60V Max* or a 120V Max* (two 60V Max* batteries) product, it will operate as a 60V Max* battery.
Shipping Mode: When the cap is attached to the FLEXVOLT™ battery, the battery is in Shipping Mode. Strings of cells are electrically disconnected within the pack resulting in three batteries with a lower Watt hour (Wh) rating as compared to one battery with a higher Watt hour rating. This increased quantity of three batteries with the lower Watt hour rating can exempt the pack from certain shipping regulations that are imposed upon the higher Watt hour batteries.

The battery label indicates two Watt hour ratings (see example). Depending on how the battery is shipped, the appropriate Watt hour rating must be used to determine the applicable shipping requirements. If utilizing the shipping cap, the pack will be considered 3 batteries at the Watt hour rating indicated for "Shipping". If shipping without the cap or in a tool, the pack will be considered one battery at the Watt hour rating indicated next to "Use".
Example of Use and Shipping Label Marking
USE: 120 Wh
Shipping: 3 x 40 Wh
For example, Shipping Wh rating might indicate 3 x 40 Wh, meaning 3 batteries of 40 Watt hours each. The Use Wh rating might indicate 120 Wh (1 battery implied).

Fuel Gauge Battery Packs (Fig. B)
Some DeWALT battery packs include a fuel gauge which consists of three green LED lights that indicate the level of charge remaining in the battery pack.
The fuel gauge is an indication of approximate levels of charge remaining in the battery pack according to the following indicators:

To actuate the fuel gauge, press and hold the fuel gauge button. A combination of the three green LED lights will illuminate designating the level of charge left. When the level of charge in the battery is below the usable limit, the fuel gauge will not illuminate and the battery will need to be recharged.

NOTE: The fuel gauge is only an indication of the charge left on the battery pack. It does not indicate tool functionality and is subject to variation based on product components, temperature and end-user application.
For more information regarding fuel gauge battery packs, please call 1-800-4-DeWALT (1-800-433-9258) or visit our website www.dewalt.com.

Important Safety Instructions for All Battery Chargers

• DO NOT attempt to charge the battery pack with any chargers other than the ones in this manual. The charger and battery pack are specifically designed to work together.
• These chargers are not intended for any uses other than charging DeWALT rechargeable batteries.
  Any other uses may result in risk of fire, electric shock or electrocution.
• DO NOT expose the charger to rain or snow.
• Pull by the plug rather than the cord when disconnecting the charger. This will reduce the risk of damage to the electric plug and cord.
• Make sure that the cord is located so that it will not be stepped on, tripped over or otherwise subjected to damage or stress.
• DO NOT use an extension cord unless it is absolutely necessary. Use of improper extension cord could result in risk of fire, electric shock or electrocution.
• When operating a charger outdoors, always provide a dry location and use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.
• An extension cord must have adequate wire size (AWG or American Wire Gauge) for safety. The smaller the gauge number of the wire, the greater the capacity of the cable, that is, 16 gauge has more capacity than 18 gauge. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating. When using more than one extension to make up the total length, be sure each individual extension contains at least the minimum wire size. The following table shows the correct size to use depending on cord length and nameplate ampere rating. If in doubt, use the next heavier gauge. The lower the gauge number, the heavier the cord.

Minimum gauge for Cord sets

• DO NOT place any object on top of the charger or place the charger on a soft surface that might block the ventilation slots and result in excessive internal heat. Place the charger in a position away from any heat source. The charger is ventilated through slots in the top and the bottom of the housing.
• DO NOT operate the charger with a damaged cord or plug.
• DO NOT operate the charger if it has received a sharp blow, been dropped or otherwise damaged in any way. Take it to an authorized service center.
• DO NOT disassemble the charger; take it to an authorized service center when service or repair is required. Incorrect reassembly may result in a risk of electric shock, electrocution or fire.
• Disconnect the charger from the outlet before attempting any cleaning. This will reduce the risk of electric shock. Removing the battery pack will not reduce this risk.
• NEVER attempt to connect 2 chargers together.
• The charger is designed to operate on standard 120V household electrical power. DO NOT attempt to use it on any other voltage.This does not apply to the vehicular charger.

Shock hazard. DO NOT allow any liquid to get inside the charger. Electric shock may result.

Burn hazard. DO NOT submerge the battery pack in any liquid or allow any liquid to enter the battery pack. Never attempt to open the battery pack for any reason. If the plastic housing of the battery pack breaks or cracks, return to a service center for recycling.

Burn hazard. To reduce the risk of injury, charge only DeWALT rechargeable battery packs. Other types of batteries may overheat and burst resulting in personal injury and property damage.
NOTICE: Under certain conditions, with the charger plugged into the power supply, the charger can be shorted by foreign material. Foreign materials of a conductive nature, such as, but not limited to, grinding dust, metal chips, steel wool, aluminum foil or any buildup of metallic particles should be kept away from the charger cavities. Always unplug the charger from the power supply when there is no battery pack in the cavity. Unplug the charger before attempting to clean.

Charging a Battery (Fig. C)

1. Plug the charger into an appropriate outlet before inserting battery pack.

2. Insert the battery pack into the charger, making sure the battery pack is fully seated in the charger. The red (charging) light will blink continuously indicating that the charging process has started.
3. The completion of charge will be indicated by the red light remaining ON continuously. The battery pack is fully charged and may be used at this time or left in the charger. To remove the battery pack from the charger, push the battery release button on the battery pack.
   NOTE: To ensure maximum performance and life of lithiumion battery packs, charge the battery pack fully before first use.

Charger Operation
Refer to the indicators below for the charge status of the battery pack.

* DCB107, DCB112, DCB113, DCB115, DCB118, DCB132:
The red light will continue to blink, but a yellow indicator light will be illuminated during this operation. Once the battery pack has reached an appropriate temperature, the yellow light will turn off and the charger will resume the charging procedure.
The compatible charger(s) will not charge a faulty battery pack. The charger will indicate faulty battery pack by refusing to light.
NOTE: This could also mean a problem with a charger.
If the charger indicates a problem, take the charger and battery pack to be tested at an authorized service center.

hot/Cold Pack Delay
When the charger detects a battery pack that is too hot or too cold, it automatically starts a Hot/Cold Pack Delay, suspending charging until the battery pack has reached an appropriate temperature. The charger then automatically switches to the pack charging mode. This feature ensures maximum battery pack life.
A cold battery pack will charge at a slower rate than a warm battery pack. The battery pack will charge at that slower rate throughout the entire charging cycle and will not return to maximum charge rate even if the battery pack warms. The DCB118 charger is equipped with an internal fan designed to cool the battery pack. The fan will turn on automatically when the battery pack needs to be cooled. Never operate the charger if the fan does not operate properly or if ventilation slots are blocked. DO NOT permit foreign objects to enter the interior of the charger.

Electronic Protection System
Li-Ion tools are designed with an Electronic Protection System that will protect the battery pack against overloading, overheating or deep discharge.
The tool will automatically turn off if the Electronic Protection System engages. If this occurs, place the lithiumion battery pack on the charger until it is fully charged.

Wall Mounting
DCB107, DCB112, DCB113, DCB115, DCB118, DCB132
These chargers are designed to be wall mountable or to sit upright on a table or work surface. If wall mounting, locate the charger within reach of an electrical outlet, and away from a corner or other obstructions which may impede air flow. Use the back of the charger as a template for the location of the mounting screws on the wall. Mount the charger securely using drywall screws (purchased separately) at least 1" (25.4 mm) long, with a screw head diameter of 0.28–0.35" (7–9 mm), screwed into wood to an optimal depth leaving approximately 7/32" (5.5 mm) of the screw exposed. Align the slots on the back of the charger with the exposed screws and fully engage them in the slots.

Charger Cleaning Instructions

Shock hazard. Disconnect the charger from the AC outlet before cleaning. Dirt and grease may be removed from the exterior of the charger using a cloth or soft non-metallic brush. DO NOT use water or any cleaning solutions.

Important Charging NOTES

1. Longest life and best performance can be obtained if the battery pack is charged when the air temperature is between 65°F and 75°F (18 ° – 24°C). DO NOT charge when the battery pack is below +40°F (+4.5°C), or above +104°F (+40°C). This is important and will prevent serious damage to the battery pack.
2. The charger and battery pack may become warm to the touch while charging. This is a normal condition, and does not indicate a problem. To facilitate the cooling of the battery pack after use, avoid placing the charger or battery pack in a warm environment such as in a metal shed or an uninsulated trailer.
3. If the battery pack does not charge properly:
   1. Check operation of receptacle by plugging in a lamp or other appliance;

DO NOT stare into worklight. Serious eye injury could result.
There is a worklight located above the blade The worklight is activated when the trigger switch is depressed, and will automatically turn off 20 seconds after the trigger switch is released. If the trigger switch remains depressed, the worklight will remain on.
NOTE: The worklight is for lighting the immediate work surface and is not intended to be used as a flashlight.

Blades
This portable band saw is setup for use with.02" (0.5 mm) thick, 1/2" (12.5 mm) wide and 32" (813 mm) long blades. DO NOT use.025" (0.64 mm) thick blades.

The use of any other blade or accessory might be hazardous. DO NOT use any other type of accessory with your band saw. Blades used on stationary band saws are of different thickness. DO NOT attempt to use them on your portable unit.

Blade Selection
In general, first consider the size and shape of the work, and the type of material to be cut. Remember, for the most efficient cutting, the coarsest tooth blade possible should be used in a given application, because the coarser the tooth, the faster the cut. In selecting the appropriate number of teeth per inch of the band saw blade, at least two teeth should contact the work surface when the blade is rested against the workpiece. As a rule of thumb, soft materials usually require coarse tooth blades, while hard materials require fine tooth blades. Where a smoother finish is important, select one of the finer tooth blades.
Select the appropriate band saw blade according to the material type, dimensions, and number of teeth. See Bi-Metal Band Saw Blade Description chart.
The following table is intended as a general guide only. Determine the type of material and dimension of the workpiece and select the most appropriate band saw blade.
NOTICE: Never use the band saw to cut resin materials which are subject to melting. Melting of resin material caused by high heat generated during cutting may cause the band saw blade to become bound to the material, possibly resulting in overload and burn-out of the motor.

Blade Tracking (Fig. A)

To reduce the risk of serious personal injury, turn tool off and remove the battery pack before making any adjustments or removing/ installing attachments or accessories. An accidental start-up can cause injury.
NOTICE: Excessive tightening of the adjustment screws could result in damage to the saw.
Your band saw is equipped with an adjustable blade tracking mechanism which assures proper blade tracking at all times. The blade is properly adjusted when it is centered on the guide rollers and the teeth of the blade are 3/16" (0.38 mm) from the edge of the guide roller.

To Adjust the Blade Tracking

1. Turn and open the blade tension lever to allow access to the tracking screws .
2. Use a 10 mm wrench to loosen the adjustment locking nuts.
3. Use a 3 mm hex wrench to turn one of the tracking screws 1/4 turn clockwise. Turn the other tracking screw 1/4 turn clockwise.
   NOTE: Turning the tracking screw clockwise moves the blade toward the guide roller, turning the tracking screw counterclockwise moves the blade away from the guide roller.
4. Tighten both the adjusting locking nuts and close the quick release lever. (It will be necessary to run the saw to observe the tracking.)
5. Observe blade tracking between runs and repeat Steps 1–4 as necessary to achieve proper blade tracking.

ASSEMBLY AND ADJUSTMENTS

To reduce the risk of serious personal injury, turn unit off and remove the battery pack before making any adjustments or removing/ installing attachments or accessories. An accidental start-up can cause injury.

Installing and Removing the Battery Pack (Fig. A, G)
NOTE: For best results, make sure your battery pack is fully charged.
To install the battery pack into the tool handle, align the battery pack with the rails inside the tool's handle and slide it into the handle until the battery pack is firmly seated in the tool and ensure that it does not disengage. To remove the battery pack from the tool, press the release button and firmly pull the battery pack out of the tool handle. Insert it into the charger as described in the charger section of this manual.

Proper Hand Position (Fig. I)

To reduce the risk of serious personal injury,
ALWAYS use proper hand position as shown.

To reduce the risk of serious personal injury, ALWAYS hold securely in anticipation of a sudden reaction.
Whenever possible, hold the saw firmly in both hands. If the optional blade guards (Fig. I) are installed, the saw can be operated with one hand. Keep your free hand clear of the blade area and DO NOT allow the saw to fall against the clamped or supported material or your body when the cut is complete.

Cutting (Fig. A, I, J)
Refer to Figure J for recommended cutting positions for various materials.
NOTE: Select and use a band saw blade that is most appropriate for the material being cut. See Bi-Metal Band Saw Blade Description.
This portable band saw may be hung using the hang hook ( , Fig. A). Hang tool on a pipe vise or other suitable, stable structure.

To reduce the risk of injury, only use hang hook to support the weight of the tool. Never rely on the hang hook for your own support or to help you maintain your balance.

Never attempt to use this tool by resting it upside down on a work surface and bringing the material to the tool. Always securely clamp the workpiece and bring the tool to the workpiece, securely holding the tool with two hands whenever possible as shown in Figure I.

1. Mount the material to be cut solidly in a vise or other clamping device.
2. Bring the work stop into contact with the workpiece while keeping the blade off of the workpiece. Turn the saw on.
3. When saw reaches desired rotation speed, slowly and gently tilt the main body of the tool to bring the band saw blade into contact with the workpiece. DO NOT apply additional pressure in excess of the weight of the main body of the tool. Carefully avoid bringing the band saw blade suddenly and heavily into contact with the upper surface of the workpiece. This will cause serious damage to the band saw blade. To obtain maximum service life of the band saw blade, ensure there is no sudden impact at the beginning of the cutting operation.
4. As shown in Figure I, straight cutting can be accomplished by keeping the band saw blade aligned with the side surface of the motor housing. Any twisting or cocking of the blade will cause the cut to go offline and decrease the life of the blade.
   NOTICE: During cutting, if the band saw becomes locked or jammed in the workpiece material, release the switch immediately to avoid damage to the band saw blade and motor.
5. The tool's own weight provides the most efficient downward cutting pressure. Added operator pressure slows the blade and reduces blade life.
6. End pieces, which would be heavy enough to cause injury when they drop, after cut-off, should be supported. Safety shoes are strongly recommended. End pieces may be hot and sharp.

To reduce the risk of serious personal injury, the brush, brush cap and blade guard assembly must be installed for one-handed use.
NOTE: The guard assembly is available at extra cost from your local dealer or authorized service center.

Tips for Better Cutting (Fig. J)
The following recommendations should be used as a guide (refer to Figure J). Results may vary with the operator and the particular material being cut.

• Never twist the band saw blade during cutting operation.
• Never use liquid coolants with portable band saws. Use of liquid coolants will cause build-up on tires and reduce performance.
• If excessive vibration occurs during the cut, ensure that the material being cut is is securely clamped down. If vibration continues, change the band saw blade.

MAINTENANCE

To reduce the risk of serious personal injury, turn unit off and remove the battery pack before making any adjustments or removing/ installing attachments or accessories. An accidental start-up can cause injury.

Lubrication
Self-lubricating bearings are used in the tool and periodic relubrication is not required. In the unlikely event that service is ever needed, take your tool to an authorized service location.
