4. Continuously move the tool in a forward and 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.
EDGE GRINDING WITH GRINDING WHEELS
CAUTION: Wheels used for edge grinding may break or kick back if they bend or twist
while the tool is being used to do cut-off work. To reduce the risk of serious injury, limit
the use of these wheels with a standard Type 27 guard to shallow cutting and notching
(less than 1/2 inch (13mm) in depth). The open side of the guard must be positioned
away from the operator. For deeper cutting with a Type 1 cut-off wheel, use a closed
Type 1 guard. See pages 9 and 10 for more information.
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.
CAUTION: Do not use edge grinding wheels / 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.
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. Figure K - Maintain a 5˚ to 10˚ angle between the tool and work surface.
4. Continuously move the tool in a forward and 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 prevent accidental operation, turn off and
unplug tool before performing the following operations. Failure to
do this could result in serious personal injury.
NOTE: Guard may be removed when using sanding backing pads.
guard must be reinstalled for grinding wheel, sanding flap disc, cutting wheel, wire brush or
wire wheel applications after sanding applications are complete.
1. Figure L - Place or appropriately thread backing pad (14) on the spindle.
2. Place the sanding disc (15) on the backing pad (14).
3. While depressing spindle lock, thread clamp nut (13) on
spindle, piloting the raised hub on the clamp nut into the
center of san ding disc and backing pad.
4. Tighten the clamp nut by hand, then depress the spindle
lock button while turning the sanding disc until the sanding
disc and clamp nut are snug.
5. To remove the wheel, grasp and turn the backing pad and
sanding pad while depressing the spindle lock button.
USING SANDING BACKING PADS
Choose the proper grit sanding discs for your application.
Sanding discs are available in various grits. Coarse grits yield
faster material removal rates and a rougher finish. Finer grits

yield slower material removal and a smoother finish.
Begin with coarse grit discs for fast, rough material removal. Move to a medium grit
paper and finish with a fine grit disc for optimal finish.
Coarse 16 - 30 grit
Medium 36 - 80 grit
Fine Finishing 100 - 120 grit
Very Fine Finishing 150 - 180 grit
1. Allow the tool to reach full speed before touching 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. Figure M - Maintain a 5˚ to 15˚ angle between the tool and work surface. The san -
ding disc should contact approximately one inch (25mm) of work surface.
4. 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.
PRECAUTIONS TO TAKE WHEN SANDING PAINT
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.
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.
