OPERATION
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 grinder continuously at a steady, consistent
pace.
CAUTION:
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 grinder from chat-
tering or bouncing.
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 grinder away from the workpiece before turning
off.
