Belt Sander Tracking Adjustment Guide for RIDGID R2720

OPERATION

TO ADJUST SANDING BELT TRACKING

See Figure 10.

nConnect the sander to power supply.

nWith sander positioned as shown below, pull switch trig- ger and release immediately.

NOTE: This position is for adjustments only. Sanding belt should not be in contact with workpiece or any foreign ob- jects when making belt tracking adjustments.

nObserve tracking of sanding belt. If the sanding belt runs inward, slowly turn the tracking knob clockwise. If the sanding belt runs outward, slowly turn the tracking knob counterclockwise. This should be done until you are sure belt will not run off sander, or come in contact with internal parts.

NOTE: After installing a new sanding belt, it may become necessary to change the adjustment several times until the belt becomes conditioned.

nWhen you are sure the belt will not rub against internal parts, start the sander and fine adjust the tracking knob until the belt stabilizes.

When correctly adjusted, the outer edge of the belt will be even with the outer edge of the sander. Belt life will be greatly increased if a few seconds are spent adjusting the belt tracking.

NOTE: Replace a torn sanding belt immediately.

WARNING:

Keep hands and fingers away from moving sanding belt. Any part of body coming in contact with moving sanding belt could result in serious injury. Do not wear loose clothing or jewelry when operating sander. They could get caught in moving parts and foreign objects could get thrown from sander causing injury.

CAUTION:

If the sanding belt wears excessively on the inner edge it is probably adjusted too far inward and is rubbing against internal parts. If this is the case, readjust the tracking knob.
