Resetting Tensioner Spring Tension - Grizzly G0512 Instruction Manual

6.
Rotate the tension nut counter-clockwise to
increase the tension and clockwise to
decrease the tension.
— Decreased Tension: If you rotated the
tension nut clockwise, move the belt ten-
sion lever to the release position. If it is
not too stiff, continue to step 7. If it is too
stiff to move comfortably, then either the
shaft spring tension needs to be reset, the
tension shaft needs lubrication, or the
idler roller-to-platen relationship needs to
be adjusted (page 29-30).
— Increased Tension: If you rotated the ten-
sion nut counter-clockwise, check the
beginning movement of the belt tension
lever. If there is no play in the first 2" of
travel, continue to step 7. If there is play
in the first 2", then the tension shaft spring
tension needs to be reset, as described in
the next sub-section.
7.
Replace the sanding belt and examine the
effect of the tension adjustment on your belt.
Repeat the adjustment procedure if neces-
sary.

Spring Tension
The tensioner spring (shown in
applies pressure to the sanding belt when the
belt tension lever is in the tension position. When
repeated adjustments are made to the tensioner
nut, the spring tension may lose the original set-
ting from the factory, at which point it will need to
be reset.
