n

  Move the sander slowly over the work surface, using 

the rear handle to control the sander and the front 
handle to guide the sander.

  NOTE:

 

Allowing the sander to remain in one place will 

result in an uneven surface.

The sander is designed to provide the proper weight on 
the sanding belt.
If the sanding belt slips or does not track while sanding, 
you may be applying too much pressure.
Excessive pressure will result in uneven work, clogged 
sanding belts, premature sanding belt wear, possible 
motor burnout, and irregular sanding belt tracking
When this occurs, remove the sander from the workpiece. 
If you properly adjust the belt tracking, the sanding belt 
will return to its normal and correct position on the drive 
roller and front roller.
Use a coarser sanding belt for heavy sanding, not heavy 
pressure. The weight of the tool is sufficient to provide 
adequate pressure at the correct location.
The front roller of the sander is not designed for contour 
sanding. Sanding on the front roller could cause 
irregularity in the sanding belt tracking.

OPERATING THE SANDER

See Figure 10.

n

  Secure the work to prevent it from moving under the 

sander.

WARNING:

 

Unsecured work could be thrown 

towards the operator causing injury.

n

  Turn the sander on and let the motor reach its 

maximum speed before placing the sander on the work 
surface.

n

  Lower the sander to the work surface with a slight 

forward motion.

WARNING:

 Keep a firm grip on the sander with 

both hands at all times. Failure to do so could result 
in loss of control leading to possible serious injury.

PROPER HAND PLACEMENT

See Figure 9.

For ease of operation and maintaining proper control, 
the sander has a front handle and a rear handle. These 
handles allow two-handed operation, which aids in 
maintaining control, keeping the sanding area level with 
the workpiece, and keeping hands clear of the sanding 
belt. When operating the sander, always hold the front 
handle with your left hand and the rear handle with your 
right hand.

WARNING: 

Keep hands and fingers clear of 

moving sanding belt, front idler roller, and drive 
roller assembly. Failure to do so will result in serious 
personal 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.
