MAINTENANCE
WARNING:
When servicing, use only identical replacement parts.
Use of any other parts may create a hazard or cause
product damage.
WARNING:
Always wear safety goggles or safety glasses with side
shields during power tool operation or when blowing dust.
If operation is dusty, also wear a dust mask.
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.
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.
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.
