Turn the machine "OFF", and disconnect the
machine from the power source.
Remove the belt guard locking knob and upper
belt guard. Remove the screws securing the
side belt guard and then remove the side belt

Rotate the sanding belt by hand to check the
belt tracking. The belt should track to the center
of the wheels.
– When looking at the front of the sander if
the belt tracks to the left, turn the tracking
knob counterclockwise until the belt tracks
to the center of the wheels.
– When looking at the front of the sander if
the belt tracks to the right, turn the tracking
knob clockwise until the belt tracks to the
center of the wheels.
Replace the upper and side belt guards and
secure in place with the belt guard locking
knob.
Plug the power cord into the correct receptacle.
(Refer to Power Source paragraph in this section
of the manual.)
Turn the switch ON and OFF to make sure the
belt is tracking at high speed; readjust with
tracking knob if needed.
DUST PORT OPTIONS
Refer to Figure O
The dust ports can be easily connected to a dust
collection system with a large diameter shop
vacuum hose.
Sanding operations are inherently dusty. This
sander is equipped with two 1-3/4” OD x 1-1/2”
ID dust ports to help minimize the amount of
dust escaping into the surrounding air. Attach
the dust collection system vacuum hose to the
dust chute.
NOTE: The dust chute is shipped with an
adapter for use with smaller hose dust colle-
ctors. This adapter has a 1-1/4” ID and can be
used in either dust port.
