WARNING:
When servicing, use only identical replacement parts.
Use of any other parts could create a hazard or cause
product damage.
WARNING:
Always wear eye protection with side shields marked to
comply with ANSI Z87.1. Failure to do so could result in
objects being thrown into your eyes resulting in possible
serious injury.
GENERAL MAINTENANCE
Avoid using solvents when cleaning plastic parts. Most
plastics are susceptible to damage from various types of
commercial solvents and may be damaged by their use. Use
clean cloths to remove dirt, dust, oil, grease, etc.
WARNING:
Do not at any time let brake fluids, gasoline, petroleum-
based products, penetrating oils, etc., come in contact
with plastic parts. Chemicals can damage, weaken or
destroy plastic which may result in serious personal injury.
Electric tools used on fiberglass material, wallboard, spackling
compounds, or plaster are subject to accelerated wear and
possible premature failure because the fiberglass chips and
grindings are highly abrasive to bearings, brushes, commu-
tators, etc. Consequently, we do not recommend using this
tool for extended work on these types of materials. However,
if you do work with any of these materials, it is extremely
important to clean the tool using compressed air.
LUBRICATION
All of the bearings in this tool are lubricated with a sufficient
amount of high grade lubricant for the life of the unit under
normal operating conditions. Therefore, no further lubrica-
tion is required.
POWER SUPPLY CORD REPLACEMENT
If replacement of the power supply cord is necessary, this
must be done by an authorized service center in order to
avoid a safety hazard.
REPLACING BRUSH ASSEMBLIES
See Figure 9, page 13.
The angle grinder has externally accessible brush assemblies
that should periodically be checked for wear.
NOTE: ILLUSTRATIONS START ON PAGE 12
AFTER FRENCH AND SPANISH LANGUAGE SECTIONS.

MAINTENANCE

To replace brushes:
 Unplug the angle grinder.
 Remove brush cap with a screwdriver. Brush assembly
is spring loaded and will pop out when you remove
brush cap.
 Remove brush assembly (brush and spring).
 Check for wear. If worn, always replace in pairs. Do not
replace one side without replacing the other.
 Reassemble using new brush assemblies. Make sure
curvature of brush matches curvature of motor and that
brush moves freely in brush tube.
 Make sure brush cap is oriented correctly (straight) and
replace.
 Tighten brush cap securely. Do not overtighten.
GUARD REPLACEMENT
See Figure 10, page 13.
After extended use, the guard may become worn and need
adjustment or replacing. Or, if you drop the angle grinder
and damage the guard, it may be necessary to replace it.
To replace the guard:
 Unplug the angle grinder.
 Depress spindle lock button and rotate nut with provided
wrench until spindle locks.
NOTE: To prevent damage to the spindle or spindle lock,
always allow motor to come to a complete stop before
engaging spindle lock.
 Using the wrench provided, loosen and remove nut,
grinding wheel, and disc flange from spindle if necessary.
 Unlock the guard clamp lever.
 Remove the guard.
 Place the new guard on the shoulder of the bearing cap,
aligning the arrow with the slot on the bottom of the angle
grinder.
NOTE: If the new guard will not fit, loosen the clamp
screw until it will slide over the bearing cap. Be sure the
tabs on the guard are seated in the groove in the bearing
cap.
 Rotate guard to the correct position. Refer to Positioning
the Guard earlier in this manual.
 Lock the guard clamp lever.
 Tighten clamp screw securely if needed.
 Reinstall grinding wheel. Refer to Installing/Replacing
Grinding Wheel earlier in this manual.
