Maintenance

•
Ensure that the brush is parallel to the roller with
1.5 mm (0.060 inch) clearance to light contact.
•
Grease the fittings every 50 hours and after every
washing.
•
When replacing a roller brush, torque the J-bolts
to 2 to 3 N∙m (20 to 25 in-lb).
•
When replacing the brush-shaft-driven pulley,
torque the nut to 36 to 45 N∙m (27 to 33 ft-lb).
•
When replacing the brush-drive pulley, apply 242
Loctite (blue) and torque the bolt to 20 to 26 N∙m
(15 to 19 ft-lb).
Note:
The roller brush, the idler bearing, and the belt
are considered consumable items.
