7.7- Belt tension adjustment and replacement
The motor is fixed on a movable base that can be
adjusted by tightening or loosening the sticks (2).
NOTE: Before adjusting the tensioning across the
sticks, must loosen the nuts (B) for the supports (A) can
move easily.
The adjustment is made as follows:
1º- By pushing the sticks, the motor is displaced in the
opposite direction of the machine, thus the belt is
tensioned.
2º- When the sticks is released, the motor is displaced in
the machine direction, thereby the belt tension is
relieved.
NOTE: Do not let the belt completely loose! The
clearance (deflection) should be between 5 and 10 mm.
Check the belt tension (1) each 50 work hours or
weekly and if you assemble a motor, according
instructions on next page.
Motor assembly:
1- Adjust the supports (A) so that the spacing is the
same as the motor base.
2- Next, place the motor in the support, turn the screw
(3) and washer (4) and segure with the washer (5) and
nut (6) in the four extremities of the motor base.

Do not forget to re-install the protective
covers. Never operate the machine
without it!
Notes:
1- Grease, oil and dust attack the belt,
generating premature damaging. Therefore,
maintain the belts always very clean.
2- If the belts prevent drying, peeling and/or
free fibers, change them immediately.
