Clean the belt guides and the pulleys.
1. Use a vacuum assembly (option) to suction
the belt wear debris on the belt guides and
sensors, etc.
2. Use a plastic spatula or similar tool to
remove the belt wear debris adhering to the
outer peripheral surface of the pulleys.
3. Use a brush or similar tool to remove the
belt wear debris caught in the belt guides.
c
CAUTION
Use plastic spatula or brush to avoid scratching the pulley
or guide.
c
CAUTION
Do not use any solvent (such as IPA) except of heavy
soiling. Use absolute ethanol and make sure not to pour
the solvent over the pulley bearing upon cleaning.

Attach the new belt by the reversed
procedure of Step4 and Step5.
1. Attach the new belt temporarily while putting
it on the pulley.
2. Reattach the coupling and tighten the bolt.
3. Move the pulley bracket or the pulley to the
marked position and tighten temporarily.

Measure the belt tension at the tension
measurement point with the tension
meter as shown on the right illustration.

The belt tension standard value
Tension: 23 to 34N (256 to 305Hz)

According to the results of the belt
tension measurement, change the
tension adjustment plate position to
acquire the value in the optimal range.
Fix the temporarily tightened bolt firmly after
adjustment.

on [Unit] - [Conveyor] screen to transfer
several boards, and check the motion.
4. Rotate the conveyor belt by hand and
confirm that no slack or unevenness of
rotation is found.
When any slack or unevenness of rotation is
found, check the belt assembly condition,
and readjust the position of pulley bracket
(or pulley).
