LOCKING ON THE SANDER
See Figure 8.
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 sup-
ply, 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:
n Depress the switch trigger.
n
Push in the lock-on button.
n Release the switch trigger.
n
Release the lock-on button.
NOTE:
To release the lock, depress and release the switch
trigger.
OPERATING THE SANDER
See Figure 9.
Clamp or otherwise secure the work to prevent it from mov-
ing under the sander.
WARNING:
Unsecured work could be thrown back toward
operator causing injury.
Before placing sander on work surface, squeeze the switch
trigger and let the motor reach its maximum speed, then
lower the sander to the work surface with a slight forward
motion. Using the rear handle to control the sander and the
front handle only to guide it, move it slowly over the work.
Allowing the sander to remain in one place will result in an
uneven surface.
WARNING:
Keep a firm grip on sander with both hands at all
times. Failure to do so could result in loss of control
leading to possible serious injury.
The sander was designed to provide the proper weight on
the sanding belt.
Excessive pressure will result in the following:
n
Uneven work.
n
Clogged sanding belts.
n
Premature sanding belt wear. Removal rate will not in-
crease.
n
Motor damage.
n Irregular sanding belt tracking.
NOTE: If the sanding belt moves while sanding, you may
be applying too much pressure. When this occurs, remove
sander from workpiece. If belt tracking is properly adjusted,
sanding belt will return to its normal and correct position on
the drive roller and front roller.
Use a coarser belt when heavy sanding is desired, not heavy
pressure. The importance of this cannot be over-emphasized.
Weight has been built into the tool to give the most efficient
pressure at the proper location.
NOTE: The front roller of the sander was not designed for
contour sanding. Sanding on the front roller could cause
irregularity in sanding belt tracking and will damage the
front roller.
