ADJUSTMENTS

WARNING:
To prevent accidental starting that could cause
possible serious personal injury, assemble all
parts to your cut-off machine before connecting
it to power supply. Machine should never be con-
nected to power supply when you are assembling
parts, making adjustments, installing or removing
wheels, or when not in use.
As mentioned previously your cut-off machine has been
factory assembled and adjusted. After extended use and
wear, the wheel will need to be replaced with a new one.
WARNING:
A 14 in. (356 mm) wheel is the maximum wheel
capacity of your cut-off machine. Never use a
wheel that is too thick to allow outer flange to en-
gage with the flats on the spindle. Larger wheels
will come in contact with the wheel guards, while
thicker wheels will prevent the bolt from securing
the wheel on the arbor. Either of these situations
could result in a serious accident and can cause
serious personal injury.
REMOVAL AND INSTALLATION OF WHEEL
To Remove:
See Figure 11.
WARNING:
Failure to unplug cut-off machine could result
in accidental starting causing possible serious
personal injury.

bolt that secures abrasive wheel to wheel arbor.
n Depress the spindle lock and rotate bolt until spindle
locks, preventing shaft from rotating.
n Using the arbor wrench provided, loosen and remove
bolt.
NOTE: Wheel bolt has right hand threads. Turn wheel
bolt counterclockwise to loosen.
n Remove wheel bolt, outer flange and wheel.
To Install:
See Figure 11.
n Unplug your cut-off machine.
n Inspect the replacement wheel for defects such as cracks,
chipping, and correct speed rating. If defects are found
or the speed rating is not greater than 3900 rpm, do not
use. Select another wheel.
n Clean debris from the wheel arbor.
n Place new wheel over spacer, then place both on wheel
arbor against fixed inner flange.
n Clean outer flange, then align flats with flats on wheel
arbor and slide outer flange onto arbor until it is flush.
n Place recessed side of outer flange against wheel, then
insert washer and wheel bolt into threaded end of wheel
arbor.
n Start threads and turn wheel bolt clockwise to snugly
tighten.
n Depress the spindle lock and rotate bolt until spindle
locks, preventing shaft from rotating.
n Using the arbor wrench provided, securely tighten wheel
bolt.
NOTE: Wheel bolt has right hand threads. Turn wheel
bolt clockwise to tighten.
WARNING:
Do not overtighten wheel bolt. Overtightening can
cause the new wheel to crack, resulting in prema-
ture failure and possible serious personal injury.
