OPERATION

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:

nDepress the switch trigger.

nPush in the lock-on button.

nRelease the switch trigger.

nRelease 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:

nUneven work.

nClogged sanding belts.

nPremature sanding belt wear. Removal rate will not in- crease.

nMotor damage.

nIrregular 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.
