Replacing the Sanding Belt
TO REMOVE SANDING BELT (FIG. 1)

releasing the tension on the abrasive belt.
2. Set the sander on its side so all three wheels are visible.
3. Remove the worn out belt.
TO INSTALL SANDING BELT
FIG. 2
B
1. Slip a new belt around the wheels.
Arrows printed on the inside of the belt
point in the direction in which the wheels
turn. Orient the belt in the direction of
wheel rotation. Be sure the belt does not
go over the tracking flange (B) located
on the inside of the top, front wheel as
shown in Figure 2.
2. Rotate the belt release lever (A) down
into position to reapply tension to the
belt.
NOTE: Some sanding belts are multi-
directional and do not have arrows. The
direction of rotation is also indicated on the
brush cover (C) in Figure 1.
Motor
Be sure your power supply agrees with the nameplate marking. Voltage decrease of
more than 10% will cause loss of power and overheating. D

WALT tools are factory
tested; if this tool does not operate, check power supply.
OPERATION
WARNING: To reduce the risk of serious personal injury, turn tool off and
disconnect tool from power source before making any adjustments or removing/
installing attachments or accessories. Before reconnecting the tool, depress and
release the trigger switch to ensure that the tool is off. An accidental start-up can
cause injury.
Switch Operation
• To start the belt sander , depress the trigger switch (D). Allow the belt sander to
reach operating speed before touching the work surface (Fig.1).
• To slow or stop the belt sander , release the trigger switch.
• For continuous operation , press in the lock-on button (E) while the trigger switch
is depressed and the belt sander is running.
• To release from continuous operation , squeeze the trigger and the lock will
disengage.
WARNING: BE SURE THE LOCK BUTTON IS NOT DEPRESSED BY CYCLING THE
SWITCH SEVERAL TIMES OR BY DEPRESSING AND RELEASING THE SWITCH
SEVERAL TIMES BEFORE PLUGGING IN YOUR BELT SANDER! DAMAGE TO YOUR
TOOL OR PERSONAL INJURY MAY RESULT.
Variable Speed (Fig. 1)
The variable speed control dial (K), located on the back of the rear handle, moves
the speed of the sanding belt from approximately 260 surface meters per minute on
speed #1 (light sanding; fine grit sanding belts) to approximately 420 surface meters
per minute on speed #6 (more aggressive sanding; coarse sanding belts). Low
speeds also prevent excessive belt wear and overheating when removing paint with
the belt sander.
Front Handle
There are two positions for the front handle: top position and front position. The unit
comes with the handle installed in the top position (F) as shown in Figure 1.
TO REPOSITION TOP HANDLE
1. Loosen the screw in the centre of the top handle using a Phillips screwdriver.
2. Attach the handle to the threaded hole in the front (G) or the top (F) of the unit.
3. Tighten the screw.
NOTE: The handle must be properly seated over the mounting surface before
tightening the screw.
Tracking the Belt
Your belt sander is equipped with an automatic tracking system that prevents the belt
from moving into the housing while the sander is operating. The automatic tracking
system prevents damage to the sander housing and the destruction of the sanding
belt.
