VARIABLE SPEED
See Figure 2.
The sander has a variable speed control dial,
A (slowest)
to
F (fastest), designed to allow operator control of belt
speed. To increase belt speed, turn the variable speed control
dial to a higher setting. Turn to a lower setting to decrease
belt speed. Refer to the chart on page 10 for proper speed
selections.
PROPER HAND PLACEMENT
See Figure 3.
For ease of operation the sander has an adjustable front
handle and a stationary rear handle. These handles allow
two-handed operation which aids in maintaining control,
keeping sander level with workpiece, and keeping hands
clear of sanding belt. When operating the sander always
hold the front handle with the left hand and the rear handle
with the right hand as shown.
WARNING:
Keep hands and fingers clear of moving sanding
belt, front pulley, and drive roller assembly. Failure
to do so will result in the sanding of the hands or
fingers possibly causing serious injury.
WARNING:
Do not let your fingers rest over the front or right
edge of the sander. If the sanding belt were to run
off, or if it were not properly adjusted, your fingers
could come in contact with the moving sanding
belt resulting in possible serious injury.

SOFT START FEATURE
Soft start is a feature whereby the motor gradually ramps
up to the selected top speed. For example, when a speed
is selected with the speed limiting dial and the sander is
stopped and then activated again, the sander will gradually
ramp up to the previous speed setting once the switch trig-
ger is pressed again.
