injury, always operate the grinder with the side
handle installed.
OPERATING THE GRINDER
See Figure 8, page 16.
Always carefully select and use grinding wheels that are
recommended for the material to be ground. Make sure
that the operating speed of any accessory wheel selected is
rated at 10,000 r/min. or more. The grinding wheel provided
with the grinder is suitable for grinding welds, preparing
surfaces to be welded, grinding structural steel, and grind-
ing stainless steel.
To operate the grinder:
 Secure all work in a vise or clamp to a workbench.
DANGER:
Never use the grinder with the wheel guard
removed and always be sure the wheel guard is
locked into place. It has been designed for use
only with the wheel guard installed. Attempting to
use grinder with wheel guard removed will result in
loose particles being thrown against the operator
resulting in serious personal injury.
 Hold the grinder in front and away from you with
both hands, keeping the grinding wheel clear of the
workpiece.
 Turn on the grinder and let the motor and grinding wheel
build up to full speed.
 Lower the grinder gradually until the grinding wheel con-
tacts the workpiece.
 Keep the grinder tilted at an angle from 5 to 15 de-
grees.
WARNING:
To prevent loss of control and possible serious
personal injury, always operate the grinder
with both hands, keeping 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 the grinder.
