GENERAL SAFETY RULES

Read all safety warnings and all instructions. Failure to follow the warnings and may result in electric shock, fire and/or serious injury.

Safety is a combination of common sense, staying alert and knowing how your item works. The term "power tool" in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.

SAVE THESE SAFETY INSTRUCTIONS.

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.

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.

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 a respiratory mask, non-skid safety shoes and hearing protection used for appropriate conditions will reduce the risk of personal injury.
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.

• Arsenic and chromium from chemically treated 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 with approved safety equipment such as dust masks specially designed to filter out microscopic particles. and the warning labels.

SPECIFIC RUES FOR YOUR METAL BANDSAW

Do not operate the power tool until you have read and understood the following

SAW BLADE SAFETY

1. Always wear protective gloves when handling saw blades.
2. Only use blades with correct size and type for both your Metal Bandsaw and your workpiece.
   • The size of the saw blade is 64-1/2 x 1/2 inches.
   • The blade material is bimetal with 14 TPI.
3. Never use damaged or deformed saw blades. Only use sharp blades.
4. Install the saw blade in the correct orientation indicated in the instructions (see "Changing the Saw Blade").
5. Keep hands out of path of saw blade. Never use your hands to remove metal chips by hangd. Use a brush at all times.
6. Never reach around saw blade or reach in back of the saw blade.
7. The use of accessories or attachments not recommended by the manufacturer may result in a risk of personal injury.

PERSONAL SAFETY

1. Operate in a well ventilated area. Keep the floor area around the Metal Bandsaw level and free of slippery substances or other tripping hazards.
2. Wear ANSI-approved safety goggles to protect your eyes from sparks and metal chips. Use hearing protection to protect yourself from hearing loss.
3. People with pacemakers should consult their physician(s) before use. Electromagnetic fields in close proximity to pacemakers could cause pacemaker interference or pacemaker failure.
4. Wear work gloves when handling saw blades. DO NOT wear gloves, neckties, jewelry, or loose clothing while operating the saw.
5. Metal chips are harmful to your health. Use NIOSHapproved dust masks or other respiratory protection during operation and cleaning.
6. Always turn off and unplug the Metal Bandsaw before making any adjustments or repair tasks. Never adjust the Metal Bandsaw or the workpiece while the saw is running.
7. Only use the Metal Bandsaw to cut metal.

PREPARING THE METAL BANDSAW

When transporting the Metal Bandsaw, use the transportation handle and roll the assembled saw with the wheels. Never carry the device by its guards or its accessories.

1. Examine the Metal Bandsaw for any damaged or missing parts. Replace or repair damaged parts before operation. Periodically check that all nuts, bolts and other fasteners are properly tightened.

SECURE YOUR WORKPIECE

1. To avoid blade binding or loss of control, always secure the workpiece to a stable platform, ensuring that body exposure is minimized. Use clamps to secure the workpiece. Never perform any operation freehand.
2. Ensure that work is correctly supported. Supports must be placed under the workpiece on both sides, close to the line of cut and near the edge of the workpiece.
3. For accuracy of cut, and to avoid blade binding, always use a rip fence or straight edge guide.
4. Never hand-hold a workpiece that is too small to be clamped, as it can be launched away and cause injury. Use proper support and guides to secure the small workpiece.

DURING CUTTING OPERATIONS

1. Always stand to one side when operating the saw. Never have any part of the body in line with the path of the saw. Never hold a workpiece in your hand or across your legs while cutting.
2. Ensure hands are away from the cutting area and blade. Keep one hand on the rear handle, and the other on the front grip. If both hands are holding the tool they cannot be cut by the blade.
3. Feed work into the blade against the direction of rotation of the blade only.
4. If you are interrupted when operating the saw, complete the process and switch the saw off before looking up.
5. Power tools must always be held by the insulated gripping surfaces when performing an operation, ensuring protection if the cutting tool makes contact with its own cord or hidden wiring. Contact with a 'live' wire will make exposed metal parts of the power tool 'live' and shock the operator if the insulated gripping surfaces are not used.
6. Do not use the Metal Bandsaw unless all guards are in place. Do not operate with any guard disabled, damaged, or removed. Moving guards must move freely and close instantly.
7. Turn on the Metal Bandsaw and let it reach full speed, then slowly slide the saw into the workpiece. This will help produce safer and cleaner cuts.
8. Never cut more than one piece ata time. Do not stack workpieces together. Do not attempt to cut material thicker than specified in this manual. Adjust the cutting depth to the thickness of the workpiece.
9. If a cut does not extend to the edge of the workpiece, or if the blade binds in the cut, allow the blade to come to a complete stop and lift the saw out of the workpiece.
10. Turn off tool and wait for saw blade to stop before moving workpiece or changing settings. Do not slow or stop a blade with a piece of wood or by hand. Let the blade come to rest naturally. Do not attempt to free a jammed blade while the machine is still running and connected to power.
11. Always raise the blade to be covered by the blade guard after use.

ELECTRICAL INFORMATION

GROUNDING INSTRUCTIONS

In the event of a malfunction or breakdown, grounding provides the path of least resistance for an electric current and reduces the risk of electric shock. This tool is equipped with an electric cord that has an equipment grounding conductor and a grounding plug. The plug MUST be plugged into a matching outlet that is properly installed and grounded in accordance with ALL local codes and ordinances.

1. Do not modify the plug provided. If it will not fit the outlet, have the proper outlet installed by a licensed electrician.
2. Improper connection of the equipment grounding conductor can result in electric shock. The conductor with the green insulation (with or without yellow stripes) is the equipment grounding conductor. If repair or replacement of the electric cord or plug is necessary, DO NOT connect the equipment grounding conductor to a live terminal.
3. Check with a licensed electrician or service personnel if you do not completely understand the grounding instructions or whether the tool is properly grounded.
4. Use only three-wire extension cords that have three-pronged plugs and outlets that accept the tool's plug (INSERT CR). Repair or replace a damaged or worn cord immediately.
   

In all cases, make certain the outlet in question is properly grounded. If you are not sure, have a licensed electrician check the outlet.

GUIDELINES AND RECOMMENDATIONS FOR EXTENSION CORDS

When using an extension cord, be sure to use one heavy enough to carry the current your product will draw. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating. The table below shows the correct size to be used according to cord length and ampere rating. When in doubt, use a heavier cord. The smaller the gauge number, the heavier the cord.

1. Examine extension cord before use. Make sure your extension cord is properly wired and in good condition. Always replace a damaged extension cord or have it repaired by a qualified person before using it.
2. Do not abuse extension cord. Do not pull on cord to disconnect from receptacle; always disconnect by pulling on plug. Disconnect the extension cord from the receptacle before disconnecting the product from the extension cord. Protect your extension cords from sharp objects, excessive heat and damp/wet areas.
3. Use a separate electrical circuit for your tool. This circuit must not be less than a 12-gauge wire and should be protected with a 15A time-delayed fuse. Before connecting the motor to the power line, make sure the switch is in the OFF position and the electric current is rated the same as the current stamped on the motor nameplate. Running at a lower voltage will damage the motor.

If you do not intend to use the sawing machine for a long time, remove the blade entirely (recommended) or relieve tension on the blade. This will prevent warping and prolong your blade's life.
5. Cover the bandsaw in order to protect it from dust and moisture. It is preferable to store it in its original packaging with the instruction manual and all accessories.

LUBRICATION

The bearings of your bandsaw are permanently sealed and require no extra lubrication.

REPLACING THE OIL

If undergoing normal usage, replace the oil approximately once every year. The oil quantity is 3 fl oz. (90 mL). For professional or industrial use, replace more often.

1. Open the gear box by removing the 6 screws (Fig. 23).
   
2. Drain the oil and replace it. The oil type used with your bandsaw is L-CKE gear oil, ISO VG 220 (SAE 90, AGMA 5).

CHANGING THE SAW BLADE

1. Use the head locking pin to lock the saw in the vertical position. Remove the blade cover screw and loosen the blade cover lock knob. See Fig. 24. Open the blade cover.
   
2. Move the motor-side blade guide as far as it will go toward the motor.
3. Remove the two screws holding the red blade guard onto the blade guide, then remove the blade guide. See Fig. 25.
   
4. Loosen the tension knob and slip the blade off the wheels.
5. Install the new blade through both blade guide bearings and around the bottom wheel in the same orientation as the old blade.
6. Hold the blade around the bottom wheel with one hand and slip it around the top wheel with the other hand, keeping the blade between the blade guide bearings.
7. Tighten the tension knob so the blade will not slip on the wheels upon startup. Re-install the red safety guard.

ADJUSTING THE BLADE TRACKING

Blade tracking has been set at the factory and should not require adjustment on your existing blade. If a tracking problem occurs, before making any tracking adjustments, try replacing with a new blade (see "Changing the Saw Blade" section above) and see if the tracking issue is resolved. Warped or worn blades will not track properly.

If the problem persists, adjust the machine as follows:

1. Use the head locking pin to lock the saw in the vertical position. Remove the blade cover screw and loosen the blade cover lock knob. See Fig. 24. Open the blade cover.
2. Confirm that the blade tension is set properly. Using a gloved finger, lightly press on the side of the saw blade. The blade should flex about 1/8 inch if properly tensioned. Adjust tension if necessary.
3. Run the saw and observe the blade. The blade should run next to but not tightly against the wheel flange.
4. To adjust the blade tracking, loosen the two shaft locking bolts. Slowly and carefully turn the shaft tracking bolt with a wrench, while observing the blade tracking on the wheel. See Fig. 26.
   
   • Turn the tracking bolt clockwise to track the blade closer to the wheel flange.
   • Turn the tracking bolt counterclockwise to track the blade away from the wheel flange.
     
     Blade tracking adjustment requires running the saw with the back cover open. This adjustment must only be completed by a qualified person. Failure to comply may cause serious injury.
     
     If the blade tension or tracking is improper, the blade can spring off, causing serious injury. Stand behind the saw and cover at all times when adjusting blade tracking to minimize the risk of injury. Make sure to wear safety glasses, work gloves, long work pants and a long sleeve shirt.
5. Once the blade tracking is complete, tighten the two shaft locking bolts. See Fig. 26.
6. Close the blade cover door. Tighten drive wheel cover screws. See Fig. 26.

BLADE ALIGNMENT

Check Blade tension

1. Remove the black back cover and make sure the blade is properly aligned on both wheels.
2. Adjust the blade tension until the blade sits properly centered (or does not move) on both wheels during operation

Check Blade Guard

Without the left blade guard, there is a twist on the blade due to the way it sits on the two wheels and how it is assembled. This is unavoidable (Fig. 27).

Blade Guard

Arrows show the direction the bearings can be adjusted.

Using the Blade Guard to Straighten the Blade

1. Loosen the nut on the left blade guard (Fig. 29).
   
2. Adjust the blade guard (Fig. 30). The rear bearing will be in contact with the blade (Fig. 31).
   
   NOTE: It is important to twist/adjust the blade guard in the direction as shown in figure 30. Because of how the blade is positioned on the wheels, this will help prevent the blade from sliding off of the wheel during operation.
3. Adjust the thrust bearing so that it is in contact with the blade (Fig. 32).
   
   NOTE: If the blade still continues to slip off the wheels, check if the right blade guard is causing any unnecessary twist on the blade.
