OPERATION
VARIABLE SPEED CONTROL DIAL
See Figure 2, page 14.
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 9 for proper
speed selections.
PROPER HAND PLACEMENT
See Figure 3, page 14.
The front and rear handles allow two-handed operation
which aids in maintaining control, keeping sander level
with workpiece, and keeping hands clear of sanding belt.
When carrying or 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.
TURNING ON/OFF THE SANDER
See Figure 4, page 14.
 To turn on the sander: Depress the switch trigger.
 To turn off the sander: Release the switch trigger.
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 trigger
is pressed again.
TO INSTALL/CHANGE SANDING BELT
See Figures 5 - 6, page 14.
 Unplug the sander.
 Position sander as shown.
WARNING:
Keep hands and fingers clear of front roller and
spring mechanism at all times. Failure to do so
could result in fingers getting pinched, causing
possible serious injury.
Belt tension must be released in order to install and remove
sanding belt:
 Release belt tension by lifting tension release lever.
 Install sanding belt; make sure arrow inside of belt is
pointing in the direction of rotation, which is clockwise
when looking into open side of sander.
NOTE: Match the arrow on the sanding belt to that of the
housing.
CAUTION:
If the sanding belt is not a bidirectional belt,
ensure that the arrow inside the belt is pointing
in the direction of the rotation (clockwise when
looking into the open side of the sander). Installing
unidirectional sanding belts backwards can create
a hazardous condition.
 Align the sanding belt to its correct position.
 Lower tension release lever to secure the sanding belt.
NOTE: This sander is equipped with automatic tracking,
which in most instances will cause the sanding belt to remain
centered. If the sanding belt does not stay in the center area,
manual adjustment of the belt tracking may be necessary.
To manually adjust, see Manually Adjusting Sanding Belt
Tracking in the Adjustments section of this manual.
LOCkING ON THE SANDER

The lock-on feature allows you to lock the switch trigger in
the ON position. Locking the switch trigger on allows you to
operate the sander for extended periods of time.
If you have the lock-on feature engaged during use and the
sander is accidentally disconnected from the power supply,
disengage the lock-on feature immediately. Also, do not
lock the switch trigger if you might need to suddenly stop
the sander.
To lock-on the sander:
 Depress the switch trigger.
