OPERATION
OPERATING THE GRINDER (Fig. 10)
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 6,500 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 grinding stainless steel.
To operate the grinder
Secure all work in a vise or clamp to a workbench.
■
DANGER
Never use the 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°.
■
WARNING
o 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.
■
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.
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
