OPERATION
POSITIONING THE GUARD
See Figures 4 - 6, pages 12 - 13 and figure 9, page 14.
The guard on the grinder should be correctly positioned
depending on which side the handle is mounted. Never use
the grinder without the guard correctly in place or when the
index arrows are aligned.
WARNING:
Never place the guard so that it is in front of the
grinder. This could result in serious injury because
sparks and loose particles thrown from the grinding
wheel would be directed toward the operator.
Always place the guard in the correct location as
shown.
To reposition the guard:
Remove the battery pack.
Depress guard lever and rotate the guard to its correct
position as shown.
NOTE:
Be sure the raised ridge on the guard is seated
in the groove on the bearing cap. Never use the grinder
without the guard in place and properly adjusted.
STARTING/STOPPING THE GRINDER
See Figure 7, page 13.
To turn the tool ON:
Install the battery pack.
Hold the tool in front and away from you, keeping the
wheel clear of the workpiece.
To start the tool, grasp the handle and side handle firmly.
Push the lock-out switch forward and squeeze the paddle
switch.
To turn the tool OFF:
To stop the tool, release the paddle switch. Make sure
the tool comes to a complete stop before laying down
the tool.
OPERATING THE GRINDER
See Figure 8, page 13.
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 8,500 /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 degrees
from the work surface.
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.
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.
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.
Use just enough pressure to keep the grinder from
chattering or bouncing. When too much pressure is
applied and not relieved, an overload condition may result,
causing the tool to automatically shut off.
Lift the grinder away from the workpiece before turning
off the grinder.
