pose is not recommended and creates a hazard,
which will result in serious injury.

Operating the Grinder
See Figure 8.
Always carefully select and use grinding wheels that are
recommended for the material to be ground. Make sure
that the minimum operating speed of any accessory wheel
selected is not less than 10,000/min. The grinding wheel
provided with your grinder is suitable for grinding welds,
preparing surfaces to be welded, grinding structural steel,
and grinding stainless steel.
Follow these steps to operate the grinder.
Secure all work in a vise or clamp to a workbench.
DANGER:
Never use your grinder with the guard removed. It
has been designed for use only with the guard
installed. Attempting to use grinder with 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
contacts the workpiece.
Keep the grinder tilted at an angle from 5 to 15
degrees.
Fig. 7
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
chattering or bouncing.
CAUTION:
Heavy pressure will decrease the grinder’s speed
and put a strain on the motor.
Note:
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.
