Wire Wheel And Knotted Wire Wheel
Brushes
Wire wheels and brushes can be used for removing rust, scale and
paint, and for smoothing irregular surfaces. A type 27 guard is
required when using wire brushes and wheels.
To install a wire wheel or brush, follow the steps below:
1. TURN OFF TOOL AND DISCONNECT FROM POWER SUPPLY.
2. Rest grinder on its back with the spindle pointing up and remove
guard if desired.
3. Ensure that the rated speed of the wire wheel or brush is equal to
or greater than the rated speed of the grinder found on the tool’s
nameplate.
4. Thread brush or wheel onto spindle and tighten securely.
NOTE:
Cover your hand with a glove or cloth when handling wire
wheels and brushes.
Maintenance
CLEANING
Blowing dust and grit out of the motor housing using compressed air
is a necessary regular maintenance procedure. Dust and grit
containing metal particles often accumulate on interior surfaces and
could create an electrical shock hazard if not frequently cleaned out.
ALWAYS WEAR SAFETY GLASSES.
CAUTION
: Never use solvents or other harsh chemicals for
cleaning the non-metallic parts of the tool. Use clean, dry cloth only.
LUBRICATION
D
E
WALT tools are properly lubricated at the factory and are ready
for use. Tools should be relubricated regularly every sixty days to six
months, depending on usage. (Tools used constantly on production
or heavy-duty jobs and tools exposed to heat may require more
frequent lubrication.) This lubrication should only be attempted by
trained power tool repairpersons, such as those at D
E
WALT service
centers or in other qualified service organizations.
Accessories
Recommended accessories for use with your tool are available at
extra cost from your distributor or local service center.
NOTE: USE ACCESSORIES RECOMMENDED PER CHART
BELOW.
Depressed center grinding wheels must fit within the confines of the
guard and must be rated higher than the recommended speed as
marked on the nameplate.
