OPERATING CONTROLS AND ADJUSTMENTS

STARTING AND
STOPPING SANDER
The switch (A) Fig. 15 is located on the top of the switch
box. To start the sander, move the switch to the "ON"
position. To stop the sander, move the switch to the
"OFF" position.
LOCKING SWITCH IN
THE "OFF" POSITION
IMPORTANT: When the tool is not in use, the switch
should be locked in the OFF position using a padlock (B)
Fig. 16, with a 3/16" diameter shackle to prevent
unauthorized use.
TRACKING THE BELT
The belt tracking adjustment is set at the factory so that
the abrasive belt will run true on the pulleys. If, however,
the belt should lead to either side of the pulleys, make
the adjustment by turning the tracking knob (A) Fig. 17.
Turning the knob (A) clockwise (when facing the sander)
will move the belt to the right. Turning the knob (A)
counterclockwise will move the belt to the left.
BELT TABLE ADJUSTMENTS
For most sanding operations, set the table at a 90
degree angle to the sanding belt. A 90-degree positive
stop is provided with your sander to ensure fast
positioning of the table. Adjust the positive stop as
follows:
1. Loosen the table locking lever and tilt the table to
the rear as far as possible.
2. Place a combination square on the table with the 90
degree end against the sanding belt, (Fig. 18), to visually
confirm that the table is 90 degrees to the belt.
3. If this is not the case, turn adjusting screw (A) with
wrench (B) Fig. 18, until the angle is correct.
