GENERAL POWER TOOL SAFETY WARNINGS

Read all safety warnings, instructions, illustrations and specifications provided with this power tool. Failure to follow all instructions listed below 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 mains-operated (corded) power tool or battery-operated (cordless) power tool.

WORK AREA SAFETY

• Keep work area clean and well lit. Cluttered or dark areas invite accidents.
• 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.
• Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.

ELECTRICAL SAFETY

• 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.
• 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.
• Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
• 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.
• 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.
• If operating a power tool in a damp location is unavoidable, use a ground fault circuit interrupter (GFCI) protected supply. Use of an GFCI reduces the risk of electric shock.

PERSONAL SAFETY

• 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.
• Use personal protective equipment. Always wear eye protection. Protective equipment such as a dust mask, non-skid safety shoes, hard hat or hearing protection used for appropriate conditions will reduce personal injuries.
• 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.
• 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.
• Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.
• Dress properly. Do not wear loose clothing or jewelry. Keep your hair and clothing away from moving parts. Loose clothes, jewelry or long hair can be caught in moving parts.
• 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.
• Do not let familiarity gained from frequent use of tools allow you to become complacent and ignore tool safety principles. A careless action can cause severe injury within a fraction of a second.

POWER TOOL USE AND CARE

• 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.
• 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.
• Disconnect the plug from the power source and/ or remove the battery pack, if detachable, 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.
• 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.
• Maintain power tools and accessories. 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.
• Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
• 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.
• Keep handles and grasping surfaces dry, clean and free from oil and grease. Slippery handles and grasping surfaces do not allow for safe handling and control of the tool in unexpected situations.

BATTERY TOOL USE AND CARE

• 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.
• Use power tools only with specifically designated battery packs. Use of any other battery packs may create a risk of injury and fire.
• 
  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.
• 
  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.
• Do not use a battery pack or tool that is damaged or modified. Damaged or modified batteries may exhibit unpredictable behavior resulting in fire, explosion or risk of injury.
• Do not expose a battery pack or tool to fire or excessive temperature. Exposure to fire or temperature above 265°F (130°C) may cause explosion.
• Follow all charging instructions and do not charge the battery pack or tool outside the temperature range specified in the instructions. Charging improperly or at temperatures outside the specified range may damage the battery and increase the risk of fire.

SERVICE

Adjusting Sanding Belt Tracking

After installing a new sanding belt, it is best practice to adjust the sanding belt tracking. This may take several times to properly condition the new sanding belt. Adjusting the sanding belt tracking regularly will increase the belt life.

1. Insert battery pack.
2. Position the sander upside down.
3. Pull the trigger.
4. The outer edge of the base of the sander should be even with the sanding belt when properly adjusted.
   The sanding belt should not show excessive wear on the inner edge. The sanding belt may be rubbing against internal components. If this occurs, adjust the sanding belt tracking. Depending on the placement of the sander belt choose between:
   Adjusting sanding belt inward: Slowly twist the belt adjuster knob counterclockwise.
   Adjusting sanding belt outward: Slowly twist the belt adjuster knob clockwise.

Selecting Sandpaper and Grits

Sandpaper can be made from various grit materials and these should be selected according to the material to be sanded. The guidelines below list materials and grit materials that should be used with them.

• Fine woodwork – garnet or aluminum oxide
• Rough woodwork – aluminum zirconia or ceramic aluminum oxide
• Manufactured wood products (particleboard, medium density fiber board, etc.) – silicon carbide or aluminum oxide
• Solid surface materials (Corian, quartz, granite, etc.) – silicon carbide or aluminum oxide
• Metals – emery or aluminum oxide

Sandpaper is also graded by coarseness. Start your work with an abrasive grit just coarse enough to remove high spots and excessive roughness. Follow with a second sanding using a grit one or two grades finer. Continue with successively finer grits until you obtain the desired finish.
Do not switch from a coarse grit to a very fine grit in one step because it may be difficult to remove the marks made by the coarse grit abrasive. Use the finest grits practical for the roughing operation, and finish by using successively finer grits.

Collected sanding dust from sanding surface coatings such as polyurethanes, linseed oil, etc. can self-ignite in the sander dust bag or elsewhere and cause fire.
To reduce the risk of fire always empty the dust bag frequently (10-15 minutes) while sanding and never store or leave a sander without totally emptying its dust bag. Also follow the recommendations of the coatings manufacturers.
Do not use the dust bag when sanding metal. This causes a fire hazard and can result in serious injury.

Using the Dust Bag

The dust bag provides a dust collection for the sander. To use the dust bag:

1. Remove battery pack.
2. To insert, push the tab in the open position while sliding the dust bag adapter into the sander's dust port.
3. To remove, push the tab in the open position while pulling the dust bag away from the sander's dust port.
4. To empty, unzip the dust bag. Empty dust from the dust bag holding away from the user's face and tapping dust bag into a trash can, pail or other reasonable container. Do not clean dust bag with water or compressed air.
   For more efficient operation, empty the dust bag when it is no more than half full. This will allow the air to flow better through the dust bag. Always empty thoroughly upon completion of a sanding operation and before storing the sander.

When sander is not connected to vacuum, always reinstall dust bag assembly back onto sander. Failure to do so could cause sanding dust or foreign objects to be thrown into face or eyes which could result in possible serious injury.

Universal Hose Adapter

Use the universal hose adapter to attach the sander to a vacuum hose.

1. Remove the battery pack.
2. Remove the dust bag from the sander.
3. To insert, slide the universal hose adapter into the sander's dust port. Push sander and adapter together firmly. Connect the vacuum hose to the adapter.
4. To remove, disconnect the vacuum hose from the adapter. Then, grasp the sander and adapter firmly and pull apart.

OPERATION

To reduce the risk of injury, always wear proper eye protection marked to comply with ANSI Z87.1.
When working in dusty situations, wear appropriate respiratory protection or use an OSHA compliant dust extraction solution.
To reduce the risk of injury, keep hands and body away from a moving sanding belt. Do not wear loose clothing or jewelry when operating sander.
They could get caught in moving parts causing serious injury. Keep head away from sander and sanding area. Hair could be drawn into sander causing serious injury.

Speed Dial

The speed dial allows the sander to operate at variable speeds - from low speed (1) to high speed (5).

1. To increase speed, turn the dial to a higher setting.
2. To decrease speed, turn the dial to a lower setting.

Finish sanding can produce clouds of fine dust that could ignite in the presence of sparks or open flame. Always wear a suitable dust mask or respirator and use sander in a well-ventilated area.

To reduce the risk of injury, inspect for and remove all raised nails and fasteners from workpiece before sanding. Striking a fastener while sanding could cause loss of c ontrol.

Adjusting the Front Handle

1. Remove battery pack.
2. Pull the lever in the middle of the handle all the way back into the open position.
3. Slide the handle to one of the two predeteremined detents.
4. Push the lever down to the closed position.

Properly secure workpiece before sanding. Unsecured work could be thrown towards the operator causing injury.

Using the Device

1. Secure the workpiece before starting the belt sander. Select the proper speed for the workpiece.
2. To start the sander, grasp both handles and pull the trigger letting the sander reach maximum speed before placing on the workpiece.
   NOTE: LEDs will turn on when the trigger is pulled and will go off shortly after the trigger is released.
3. Slowly move the sander on the workpiece while applying same constant pressure. Do not let the sander remain in one spot. This will result in an uneven surface.
4. To stop the tool, release the trigger. Ensure the tool has come to a complete stop before laying the tool down.

Removing Paint or Varnish

1. When removing several layers of paint or varnish, remove as much as possible with a paint solvent or varnish remover.
2. Scrape away the residue with a putty knife or other scraping tool and allow the surface to cool and dry before applying sander to the workpiece.
3. Select a coarse grit sandpaper to help prevent the sandpaper from clogging.

To reduce the risk of fire and explosion, paint solvents and varnish removers must be removed from the workpiece and the workpiece must be completely dry before sanding.

4. Keep the sander moving over new areas to avoid heating and softening the old coating (paint or varnish).
5. Work in wide, overlapping strokes to produce a uniform finish.
6. As the workpiece begins to show through the old coating, switch to a medium grit sandpaper to avoid scratching the surface of the workpiece. Gradually switch to a fine grit sandpaper until you achieve the desired finish.

MAINTENANCE

To reduce the risk of injury, always unplug the charger and remove the battery pack from the charger or tool before performing any maintenance. Never disassemble the tool, battery pack or charger. Contact a MILWAUKEE service facility for ALL repairs.

Maintaining Tool
