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.
