ASSEMBLY
WARNING:
Do not attempt to modify this product or create
accessories or attachments not recommended for use
with this product. Any such alteration or modification
is misuse and could result in a hazardous condition
leading to possible serious personal injury.
INSTALLING GRINDING WHEEL
See Figure 1, page 11.
DANGER:
Never attach a wood cutting or carving blade of any
type to this grinder. It is only designed for grinding
and sanding. Use for any other purpose is not
recommended and creates a hazard, which will result
in serious injury.
WARNING:
Thoroughly inspect a new grinding wheel before you
install it on the grinder.
To install:
 Remove the battery pack.
 Inspect the wheel.
• Tap lightly around the wheel using a wooden
hammer.
• Listen carefully to the resulting sounds. Places with
fissures or cracks will result in a different sound.
NOTE: Do not use a wheel containing fissures or cracks.
When you install a new grinding wheel, carry out a no
load revolution test of approximately one minute with
the grinding wheel facing a safe direction, i.e., away from
people or objects.
 Depress the spindle lock button and rotate the clamp nut
until the spindle locks.
NOTE: To prevent damage to the spindle or spindle lock,
always allow motor to come to a complete stop before
engaging spindle lock.
 Loosen and remove the clamp nut from the spindle. Do
not remove the disc flange.
 Make sure the flats on the bottom of the disc flange are
engaged with the flats on the spindle.
 Place the grinding wheel over the spindle.
WARNING:
Always install a grinding wheel with the depressed
center against the disc flange. Failure to do so will
cause the grinding wheel to crack when tightening the
clamp nut. This could result in serious personal injury
because of loose particles breaking off and being
thrown from the grinder. Do not overtighten.
 Thread the clamp nut on the spindle with the flat side of
the nut facing up.
 Fit the raised, small diameter portion of the clamp nut
into the hole in the wheel and finger tighten.
 Depress the spindle lock button and rotate the wheel
clockwise until the spindle locks in position.
 Tighten the clamp nut securely with the wrench provided.
Do not overtighten.
ATTACHING THE GUARD INSERT
See Figure 2, page 11.
WARNING:
Always attach the guard insert to the wheel guard when
using a cutting wheel. Failure to use the guard insert
could result in serious personal injury.
Always install the guard insert before performing cutting
operations. When attached correctly, the guard insert and
wheel guard provide protection on both sides of the cutting
wheel.
 Install wheel guard and cutting wheel.
 Place the edge of the guard insert closest to the label
over the edge of the wheel guard.
NOTE: The label on the guard insert should be pointing
away from the cutting wheel.
 Slide the guard insert over the grinding wheel and rotate
it until the tab snaps into place.
 To remove, pull the tab away from the wheel guard and
rotate guard insert off of the wheel guard.
INSTALLING THE SIDE HANDLE
See Figure 3, page 11.
WARNING:
The side handle must always be used to help prevent
loss of control and possible serious injury.
The side handle can be installed on the top, left, or right side
of the grinder, depending on operator preference.
To install:
 Remove the battery pack.
 Insert the side handle into the desired operating position.
 Turn the side handle clockwise to securely tighten.
