c. Sanding should be done in a manner to reduce tracking of paint dust
outside the work area.


a. 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
b. 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.
c. All toys, washable furniture and utensils used by children should be washed
thoroughly before being used again.
Removing Disc
Using a cloth or glove to protect your hand, turn the disc assembly counter-
clockwise to remove it from the tool spindle. Hold the spindle in place by
engaging the lock pin.
Grinding With Depressed Center Wheels (5/8"—11 Spindle)
Depressed center wheels may be used for moderate metal removal on flat or
contoured surfaces.
CAUTION: Never use depressed center wheels without the proper guard.
To install depressed center wheels:
1. Be sure tool is disconnected from power supply and switch is in "OFF"
2. Be sure the guard assembly is securely attached to the gear case.
3. Put the backing flange onto the tool spindle as shown in Figure 5.
4. Check rated speed on depressed center wheel. Never use wheel with rated
speed lower than the speed on the nameplate of the tool.
5. Place the depressed center wheel on the tool spindle as shown.

6. Thread the clamp washer on tool spindle as shown. Hold the tool spindle by
engaging the spindle lock pin, and tighten clamp washer with wrench.
When using a depressed center wheel, hold the tool so that an angle of
approximately 30° exists between the wheel and the work.
Wire Cup and Knotted Wire Wheel Brushes.
1. Disconnect tool from power source and make sure switch is "OFF". Rest
grinder on its back with spindle facing up.
2. Ensure that the rated speed of the wire brush is equal to or higher than the
rated speed of the grinder found on the nameplate.
3. Thread brush onto spindle and tighten.
Common applications for knotted wire cup brushes include cleaning welds,
angles, corners and removing paint.
Usage of the knotted wire wheel brush is the same as the wire cup brush. They
can also be used to finish irregular surfaces and corners.
Use only mild soap and a damp cloth to clean the tool. Never let any liquid get
inside the tool; never immerse any part of the tool into a liquid.
IMPORTANT: To assure product SAFETY and RELIABILITY, repairs, maintenance
and adjustment should be performed by authorized service centers or other
qualified service organizations, always using identical replacement parts.
MASTER MECHANIC tools are properly lubricated at the factory and are ready
for use.
Blowing dust and grit out of the motor housing using compressed air is a
necessary regular maintenance procedure. Dust and grit containing particles
from metal grinding often accumulate on interior surfaces and could create an
electrical shock hazard if not frequently cleaned out.
CAUTION: Never use solvents or other harsh chemicals for cleaning the non-
metallic parts of the tool. Use clean, dry rag only.
