Place wheel against the backing flange, centering the wheel on the raised section (pilot) of the backing flange. 3. While depressing the spindle lock button, thread the clamp nut (G) on spindle. If the wheel you are installing is more than 3.17 mm (1/8") thick, place the threaded clamp nut on the spindle so that the G 12 1. Allow the tool to reach full speed before touching the tool to the work surface. 2. Apply minimum pressure to the work surface, allowing the tool to operate at high speed. Grinding rate is greatest when the tool operates at high speed. 3. Position yourself so that the open-underside of the wheel is facing away from you. 4. Once a cut is begun and a notch is established in the workpiece, do not change the angle of the cut. Changing the angle will cause the wheel to bend and may cause wheel breakage. Edge grinding wheels are not designed to withstand side pressures caused by bending. 5. Remove the tool from the work surface before turning the tool off. Allow the tool to stop rotating before laying it down. WARNING: Do not use edge grinding/cutting wheels for surface grinding applications because these wheels are not designed for side pressures encountered with surface grinding. Wheel breakage and serious personal injury may result. SURFACE FINISHING WITH SANDING FLAP DISCS 1. Allow the tool to reach full speed before touching the tool to the work surface. 2. Apply minimum pressure to work surface, allowing the tool to operate at high speed. Sanding rate is greatest when the tool operates at high speed. 3. Maintain a 5˚ to 10˚ angle between the tool and work surface. 4. Continuously move the tool in a forward and 5˚-10˚ back motion to avoid creating gouges in the work surface. 5. Remove the tool from work surface before turning tool off. Allow the tool to stop rotating before laying it down. MOUNTING SANDING BACKING PADS WARNING: To reduce the risk of serious personal injury, turn tool off and and remove battery pack before making any adjustments or removing/installing attachments or accessories. NOTE: Guard may be removed when using sanding backing pads CAUTION: Proper guard must be reinstalled for grinding wheel, sanding flap disc, wire brush or wire wheel applications after sanding applications are complete. 1. Place or appropriately thread backing pad (Q) on the spindle. 2. Place the sanding disc (R) on the backing pad (Q). 3.

Move the tool constantly in a straight line to prevent burning and swirling of work surface. Allowing the tool to rest on the work surface without moving, or moving the tool in a circular motion causes burning and swirling marks on the work surface. 5. Remove the tool from work surface before turning tool off. Allow the tool to stop rotating before laying it down. 13 Precautions To Take When Sanding Paint During clean up, children and pregnant women should be kept away from the immediate work area. 3. All toys, washable furniture and utensils used by children should be washed thoroughly before being used again. 1. Sanding of lead based paint is NOT RECOMMENDED due to the difficulty of controlling the contaminated dust. The greatest danger of lead poisoning is to children and pregnant women. 2. Since it is difficult to identify whether or not a paint contains lead without a chemical analysis, we recommend the following precautions when sanding any paint: PERSONAL SAFETY 1. No children or pregnant women should enter the work area where the paint sanding is being done until all clean up is completed. 2. A dust mask or respirator should be worn by all persons entering the work area. The filter should be replaced daily or whenever the wearer has difficulty breathing. NOTE: Only those dust masks suitable for working with lead paint dust and fumes should be used. Ordinary painting masks do not offer this protection. See your local hardware dealer for the proper N.I.O.S.H. approved mask. 3. NO EATING, DRINKING or SMOKING should be done in the work area to prevent ingesting contaminated paint particles. Workers should wash and clean up BEFORE eating, drinking or smoking. Articles of food, drink, or smoking should not be left in the work area where dust would settle on them. ENVIRONMENTAL SAFETY 1. Paint should be removed in such a manner as to minimize the amount of dust generated. 2. Areas where paint removal is occurring should be sealed with plastic sheeting of 4 mils thickness. 3. Sanding should be done in a manner to reduce tracking of paint dust outside the work area. CLEANING AND DISPOSAL 1. All surfaces in the work area should be vacuumed and thoroughly cleaned daily for the duration of the sanding project. Vacuum filter bags should be changed frequently. 2. Plastic drop cloths should be gathered up and disposed of along with any dust chips or other removal debris. They should be placed in sealed refuse receptacles and disposed of through regular trash pick-up procedures. MOUNTING AND USING WIRE BRUSHES AND WIRE WHEELS Wire cup brushes or wire wheels screw directly on the grinder spindle without the use of flanges. Use only wire brushes or wheels provided with a 14 x 2 mm threaded hub. A Type 27 guard is required when using wire brushes and wheels. CAUTION: To reduce the risk of personal injury, wear work gloves when handling wire brushes and wheels. They can become sharp. CAUTION: To reduce the risk of damage to the tool, wheel or brush must not touch guard when mounted or while in use. Undetectable damage could occur to the accessory, causing wires to fragment from accessory wheel or cup. MOUNTING WIRE CUP BRUSHES AND WIRE WHEELS WARNING: To reduce the risk of serious personal injury, turn tool off and and remove battery pack before making any adjustments or removing/installing attachments or accessories. 1. Thread the wheel on the spindle by hand. 2. Depress spindle lock button and use a wrench on the hub of the wire wheel or brush to tighten the wheel. 3. To remove the wheel, reverse the above procedure. CAUTION: To reduce the risk of damage to the tool, properly seat the wheel hub before turning the tool on. USING WIRE CUP BRUSHES AND WIRE WHEELS Wire wheels and brushes can be used for removing rust, scale and paint, and for smoothing irregular surfaces. NOTE: The same precautions should be taken when wire brushing paint as when sanding paint (Refer to Precautions To Take When Sanding Paint). 1. Allow the tool to reach full speed before touching the tool to the work surface. 2. Apply minimum pressure to work surface, allowing the tool to operate at high speed. Material removal rate is greatest when the tool operates at high speed. 14 4. Close the guard latch to secure the on guard the gear case cover. You should be unable to rotate the guard by hand when the latch is in closed position. Do not operate grinder with a loose guard or clamp lever in open position. 5. To remove the guard, open the guard latch, rotate H the guard so that the lugs and slots are aligned and pull up on the guard. NOTE: The guard is pre-adjusted to the diameter of the gear case hub at the factory. If, after a period of time, the guard becomes loose, tighten the adjusting screw (O) with the clamp lever in the closed position with guard O installed on the tool. CAUTION: To reduce the risk of damage to the tool, do not tighten adjusting screw with clamp lever in open position. Undetectable damage to guard or mounting hub may result. MOUNTING CUTTING WHEELS WARNING: To reduce the risk of serious personal injury, turn tool off and and remove battery pack before making any adjustments or removing/installing attachments or accessories. CAUTION: Matching diameter threaded backing flange and clamp nut (included with tool) must be used for cutting wheels. 1. Place the unthreaded backing flange on spindle with the raised section (pilot) facing up. The raised section (pilot) on the backing flange will be against the wheel when the wheel is installed. Be sure the backing flange recess is seated onto the flats of the spindle by pushing and twisting the flange before placing the wheel. 2. Place the wheel on the backing flange, centering the wheel on the raised section (pilot). 3. Install the threaded clamp nut with the raised section (pilot) facing away from the wheel. 4. Depress the spindle lock button and tighten clamp nut with a wrench. 5. To remove the wheel, grasp and turn while depressing the spindle lock button. 3. Maintain a 5˚ to 10˚ angle between the tool and work surface for wire cup brushes. 4. Maintain contact between the edge of the wheel and the work surface with wire wheels. 5. Continuously move the tool in a forward and back 5˚-10˚ motion to avoid creating gouges in the work surface. Allowing the tool to rest on the work surface without moving, or moving the tool in a circular motion causes burning and swirling marks on the work surface. 6. Remove the tool from the work surface before turning the tool off. Allow the tool to stop rotating before setting it down. CAUTION: Use extra care when working over an edge, as a sudden sharp movement of grinder may be experienced. MOUNTING AND USING CUTTING (TYPE 1) WHEELS Cutting wheels include diamond wheels and abrasive discs. Abrasive cutting wheels for metal and concrete use are available. Diamond blades for concrete cutting can also be used. WARNING: A closed, 2-sided cutting wheel guard is included with this tool and is required when using cutting wheels. Failure to use proper flange and guard can result in injury resulting from wheel breakage and wheel contact. See pages 9 and 10 for more information. MOUNTING CLOSED (TYPE 1) GUARD U WARNING: To reduce the risk of serious personal injury, turn tool off and and remove battery pack before making any adjustments or removing/installing attachments or accessories. 1.

Push the guard down until the guard lug engages and rotates freely in the groove on the gear case hub. 3. Rotate guard (H) into desired working position. The guard body should be positioned between the spindle and the operator to provide maximum operator protection. 15 • USING CUTTING WHEELS WARNING: Do not use edge grinding/cutting wheels for surface grinding applications because these wheels are not designed for side pressures encountered with surface grinding. Wheel breakage and injury may result. 1. Allow tool to reach full speed before touching tool to work surface. 2. Apply minimum pressure to work surface, allowing tool to operate at high speed. Cutting rate is greatest when the tool operates at high speed. 3. Once a cut is begun and a notch is established in the workpiece, do not change the angle of the cut. Changing the angle will cause the wheel to bend and may cause wheel breakage. 4. Remove the tool from work surface before turning tool off. Allow the tool to stop rotating before setting it down. Support large panels to minimize the risk of wheel pinching and kickback. Large panels tend to sag under their own weight. Support must be placed under the panel on both sides, near the line of cut and near the edge of the panel. MAINTENANCE WARNING: Shock Hazard. To reduce the risk of serious personal injury, turn tool off and disconnect tool from power source before making any adjustments or removing/installing attachments or accessories. Cleaning WARNING: Blow dirt and dust out of all air vents with clean, dry air at least once a week. To minimize the risk of eye injury, always wear ANSI Z87.1 approved eye protection when performing this. CAUTION: Never use solvents or other harsh chemicals for cleaning the nonmetallic parts of the tool. These chemicals may weaken the plastic materials used in these parts. Use a cloth dampened only with water and mild soap. Never let any liquid get inside the tool; never immerse any part of the tool into a liquid. Causes and Operator Prevention of Kickback • Kickback is a sudden reaction to a pinched, bound or misaligned wheel, wire brush or flap disc causing an uncontrolled cut-off tool to lift up and out of the workpiece toward the operator. • When the wheel is pinched or bound tightly by the workpiece, the wheel stalls and the motor reaction drives the unit rapidly back toward or away from the operator. • Kickback is the result of tool misuse and/or incorrect operating procedures or conditions and can be avoided by taking proper precautions as given below: • Maintain a firm grip with both hands on the unit and position your body and arm to allow you to resist kickback forces. Kickback forces can be controlled by the operator, if proper precautions are taken. • When wheel is binding, or when interrupting a cut for any reason, release the trigger and hold the unit motionless in the material until the wheel comes to a complete stop. Never attempt to remove the unit from the work or pull the unit backward while the wheel is in motion or kickback may occur. Investigate and take corrective actions to eliminate the cause of wheel binding. • When restarting a cut-off tool in the workpiece, check that the wheel is not engaged into the material. If wheel is binding, it may walk up or kickback from the workpiece as the tool is restarted. CHARGER CLEANING INSTRUCTIONS WARNING: Shock hazard.
