ROTATING HANDLE
See Figure 4, page 12.
The handle can be rotated 90˚ to the left and right.
 Remove battery packs.
 Depress the handle lock button and rotate the handle to
the desired position.
 Release handle lock button and make sure handle is
locked into position.
POSITIONING THE GUARD
See Figures 5 - 7, page 13 and Figure 10, 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 battery packs.
 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.

OPERATING THE GRINDER
See Figure 9, 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 6,700 /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 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.
NOTICE:
Never cover air vents. They must always be open
for proper motor cooling.
 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 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.
