To operate the grinder:
 Secure all work before beginning any operation. Secure
small workpieces in a vise or clamp to a workbench.
 Hold the angle grinder in front and away from you with
both hands, keeping the grinding wheel clear of the
workpiece.
 Start the angle grinder and let the motor and grinding
wheel build up to full speed.
 Gradually lower angle grinder until the grinding wheel
contacts the workpiece.
 Keep the angle grinder tilted at an angle from 5° and 15°.
WARNINg:
To prevent loss of control and possible serious personal
injury, always operate the grinder with both hands, keep-
ing one hand on the side handle.
 Move the angle grinder continuously at a steady, consis-
tent pace.
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.
OPERATION
notice:
If the grinder is held in one spot too long, it will gouge
and cut grooves in the workpiece. If the grinder is held
at too sharp an angle, it will also gouge the workpiece
because of concentration of pressure on a small area.
 Use just enough pressure to keep the angle grinder from
chattering or bouncing. Heavy pressure will decrease its
speed and put a strain on the motor.
NOTE: Heavy pressure will decrease the grinder's speed
and put a strain on the motor. Normally the weight of the
tool alone is adequate for most grinding jobs. Use light
pressure when grinding jagged edges or loose bolts where
there is the potential for the grinder to snag on the metal
edge.
 Lift the angle grinder away from the workpiece before
turning the angle grinder off.
MAINTENANCE
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.
