Clean the belt guides and pulleys.
1. Use a vacuum assembly (option) to suck
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.

CAUTION
Use a plastic spatula and brush to avoid scratching the
pulleys and guides.

CAUTION
Do not use a solvent (IPA, etc.) unless the guides and
pulleys are excessively dirty. If using ethanol, be careful
not to spill the ethanol on the bearing in the pulleys
during cleaning.
e
Replace the conveyor belt.
1. Reattach a new belt temporarily while
putting it on the pulley.
2. (YSM20R Dual-stage: W2, W3) Pass the
drive pulley through the shaft.
3. Loosen the mounting bolt and connect
the shaft.
4. Move the bracket (YSM20R/YSM20WR
Single-lane/YSM20WR Dual-lane: pulley)
to the position marked in Step 4 and
install the mounting bolts.
5.
If looseness of the belt is found, adjust the
bracket (pulley) position to apply tension.
c
CAUTION
The followings are tightening torques of the tensioner
mounting bolts. Do not tighten the bolt excessively.
