so could cause an accident since wheel will not
tighten properly.

• Unplug the cut-off machine.
• Inspect the replacement wheel for defects
such as cracks, chipping, and correct speed rat-
ing. If defects are found or the speed rating is
not greater than 3 800 rpm, do not use. Select
another wheel.
• Clean debris from the inner washer and inner
flange.
• Place new wheel over spacer, then place both
on wheel arbor against inner flange.
• Clean outer flange, then align flats with flats
on wheel arbor and slide it onto arbor until it is
flush against wheel.

against the arbor, then insert the hex head bolt
into the threaded end of the wheel arbor.
• Start threads and turn bolt clockwise to snugly
tighten.

INSPECTING THE CARBON BRUSHES
The carbon brushes in the motor are expend-
able parts. If the brushes become excessively
worn, motor trouble might occur. Therefore, in-
spect the brushes periodically, and replace them
when they have become worn to the wear limit
line. Also, keep the carbon brushes clean be so
that they will slide smoothly within the brush
holders. The carbon brushes can easily be re-
moved after disassembling the brush caps with
a slotted screwdriver.
INSPECTING THE MOUNTING SCREWS
Regularly inspect each component of the power
tool for looseness. Re-tighten mounting screws
on any loose part.
WARNING: Never operate the power tool if
any components are loose, to prevent personal
injury.
STORAGE
Confirm that the trigger switch is turned OFF,
that the power plug has been removed from the
receptacle and that the lock-off button has been
removed and has been stored in a secure place,
after operation of the tool has been completed.
When the tool is not in use, keep it stored in a
dry place out of the reach of children.
LUBRICATION
Lubricate the following sliding surfaces:
Rotary portion of shaft, rotary portion of vise,
rotary portion of vise-jaw & quick vise.
CLEANING
Periodically remove chips and other waste ma-
terial from the surface of the power tool with
a damp, soapy cloth. To avoid a malfunction of
the motor, protect it from contact with oil or
water.
