Loosen the belt.
1. Before loosening the conveyor belt, mark the current position of pulley bracket (YSM20R/YSM20WR
single-lane type/YSM20WR dual-lane type: pulley mounting bolt) with a permanent marker.
2. Loosen 2 bolts mounting pulley bracket (pulley) with hex wrench (3) and move the bracket to the
end of the slotted hole (in loosening direction).
Regarding YSM20R/YSM20WR single-lane type/YSM20WR dual-lane type, loosen pulley mounting bolts
with hex wrenches (4 and 5) and move the pulley.

TIP
Regarding YSM20W Single-lane, the tensioner (pulley) locates at the downstream side of the conveyor flow direction.
Therefore the tensioner (pulley) location varies if the machine flow direction is different.
