WARNINg:
When servicing, use only identical replacement parts. Use of any
other parts may 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 pos-
sible premature failure because the fiberglass chips and grindings
are highly abrasive to bearings, brushes, commutators, etc. Con-
sequently, 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.

MAINTENANCE

FRENCH AND SPANISH LANgUAgE SECTIONS.
WARNINg:
Never place the guard so that it is on front of the angle grinder
as shown in figure 8. This could result in serious injury because
sparks and loose particles thrown from the grinding wheel would
be directed toward the operator. Always place the guard in the
correct location as shown in figures 6 and 7.
DANgER:
Never use your grinder with the guard removed. It has
been designed for use only with the guard installed.
Attempting to use grinder with guard removed will re-
sult in loose particles being thrown against the operator
resulting in serious personal injury.
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 lubrication is required.
WARNINg
To prevent accidental starting that could cause possible serious
personal injury, turn off the tool, and unplug the angle grinder
before performing any maintenance or adjustment.
gUARD REPLACEMENT
See Figure 9, page 12.
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.
 Using the wrench provided, loosen and remove nut,
grinding or accessory wheel, and disc flange from spindle if
necessary.
NOTE: To prevent damage to the spindle or spindle lock, always
allow motor to come to a complete stop before engaging spindle
lock.
 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
they 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 figures 6 and 7.
 Tighten clamp screw securely.
