SANDING BELT TENSION ADJUSTMENT
DO NOT ATTEMPT TO PERFORM ANY ADJUSTMENTS WHILE THE MACHINE IS RUNNING. ALWAYS TURN OFF AND UNPLUG THE SAN-
DER BEFORE PERFORMING ANY ADJUSTMENTS.
KEEP HANDS WELL AWAY FROM THE SANDING BELT AND ALL MOVING PARTS WHEN THE SANDER IS RUNNING.
NOTICE! Do not overtighten sanding belt tension. Overten-
sioning can cause premature wear or breakage of the
sanding belt as well as inconsistent belt tracking.
1.
Turn the lock handle
counter-clockwise to unlock
the belt tension adjustment hand wheel
.
2.
To set belt tension correctly, turn the belt tension
handwheel
clockwise (to tighten) until it can turn
no further – do not force beyond this point! Then,
relieve the tension slightly by turning the handwheel
one full turn counter clockwise.
3.
Turn the lock handle clockwise to secure the ten-
sion setting.
Helpful hint on sanding belt tension: Determining correct belt tension is somewhat subjective. It is
learned through experience and is somewhat dependant on personal preference. A properly ten-
sioned belt will last longer and be much less likely to break prematurely. If the belt is too loose, it will
slip off during operation. A belt that is too tight will break prematurely.
Though not essential, proper belt tracking (having the belt running straight and oscillating as evenly on the rollers
as possible) can prolong belt life and avoid having the belt slip off during operation. This is done by tilting the idler
roller (upper roller) slightly to keep the belt tracking evenly throughout its oscillating movement on the rollers.
Turn on the machine on for 5-10 seconds and check
(through the front window
) the position of the san-
ding belt on the sanding head upper roller (idler roller)
.
• If the belt is tracking straight and oscillating
evenly left and right on the middle of the rollers,
you are ready to sand. Proceed with normal
operations;
• If the belt is not tracking straight, adjust as fol-
lows before proceeding with normal sanding
operations.
Note: Belt tracking adjustments may be necessary after changing or replacing a sanding belt, to coun-
terbalance for unevennesses between sanding belts.
