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 product 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.
POWER SUPPLy CORd REPLACEMENT
If replacement of the power supply cord is necessary, this
has to be done by an authorized service center in order to
avoid a safety hazard.
WARNING
:
To prevent accidental starting that could cause possible
serious personal injury, turn off and unplug the tool before
performing any maintenance or adjustment.
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.
MAINTENANCE
REPLACING GRINdING WHEEL
See Figure 15.
WARNING:
Thoroughly inspect a new grinding wheel before you
install it on the grinder.
• Tap lightly around the wheel using a wooden
hammer.
• Listen carefully to the resulting sounds. Places with
fissures or cracks will result in a different sound.
Do not use a wheel containing fissures or cracks.
When you install a new grinding wheel, carry out a no
load revolution test of approximately one minute with
the grinding wheel facing a safe direction, i.e., away from
people or objects.
Unplug the tool.
Depress the spindle lock button and rotate the clamp nut
until the 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.
Loosen and remove the clamp nut from the spindle. Do
not remove the disc flange.
