Loosen the belt.
1. Use two hex wrenches to loosen the
mounting bolt of the belt tensioner
pulley.
Hex wrench size on pulley side : 5mm
Hex wrench size on bolt side : 4mm
2. For the dual-stage exit conveyor :
Use a hex wrench (3) to loosen the bolts
(2 locations) that secure the pulley
bracket.
3. Move the belt tensioners (pulley/pulley
bracket) to the end of the tension
adjusting slots (in the loosening
direction).

Clean the guides and 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.

Replace the conveyor belt.
1. Attach a new belt temporarily while
putting it on the pulley.
2. Tighten to secure the spline shaft with the
shaft fixing bolt.
3. Move the tensioner (pulley/pulley
bracket) that tension is applied to the
marked location in Step 4, and tighten
the bolt.
4. If looseness of the belt is found, adjust
the position of the tensioner (pulley/
pulley bracket) to apply necessary
tension.

CAUTION
Tighten the mounting bolts of the pulley and pulley
bracket to the following torques:
• Pulley mounting bolt : 5.5N•m.
• Pulley bracket mounting bolt : 3.8N•m.
Be careful not to tighten the bolts excessively.
