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.

MAINTENANCE

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.
GUARD REPLACEMENT
See Figure 7, 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 flange 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 or accessory wheel, and disc flange from spindle
if necessary.
 Using a screwdriver, loosen the clamp screw.
 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 as shown in figure 4.
 Tighten clamp screw securely.
