off and the power circuit voltage
is the same as the voltage shown
on the specification plate.
Connect the machine to a power
circuit.
2. Squeeze the trigger (A) Fig. 2 to
start the motor. Release the

VARIABLE SPEED
Model 352VS has a Variable Speed Control. The operating speed is adjustable
between 850 SFM (surface feet per minute) and 1300 SFM.
The speed is adjusted by turning the thumbwheel, (C) Fig. 2. The first position
provides the slowest operating speed (850 SFM) while position 6 is the fastest
(1300 SFM). The speed can be changed either when the motor is running or is
stopped.
TRACKING THE ABRASIVE BELT
To prevent excessive wear on both the sander and belt, NEVER allow the
abrasive belt to rub on the sander frame. To make sure that the belt is tracking
correctly, do the following:
Make sure that the trigger switch is “OFF” before con-
necting the tool to the power source.
1. Turn the tool over. Hold the rear handle with the left hand so that the ring
finger and the little finger rest on trigger (Fig. 3).
2. Squeeze the trigger to start the
motor.
3. Turn the belt aligning screw (A)
in either direction until the edge
of the belt is even with the outer
edge of the rear rubber-
covered pulley. The edge of the
belt will extend beyond the
edge of the front pulley.
4. Release the trigger to stop the
motor. Allow the tool to come to
a COMPLETE STOP before
turning it over and putting it
down.
