Periodic Maintenance
LUBRICATION
Motor lubrication: check the tag from the motor manufacturer.
Main rotor bearings are lubricated at the factory but need re-lubrication periodically. Grease fittings are
pro- vided for re-lubrication and are located on the right and left-hand bearing housings. Lubricate every
month or 750 hours, while the machine is running, with approximately 84 grams (3 oz.) of grease. Use a
lithium-based grease conforming to NLGI grade #1. More frequent lubrication may be required in
severe applications.
KNIFE SCREW TORQUE
Weekly, check the torque on the knife hold-down screws for both the rotor and the bed knives. Refer to
Section 4, Settings and Adjustments, for torque specs.
BELT TENSION
During the initial run-in period, check the belt tension at least two times in the first two days of
operation. After the initial run-in period check the belt tension on the drive monthly. Refer to the
subsection entitled Drive Belt Replacement and Adjustment in Section 4, Settings and Adjustments.
SCREEN CONDITION
Inspect the screen monthly for wear and cracks. Check the holes in the screen for elongation.
Turn the screens front-to-back monthly to even out the wear.
Refer to the instructions later in this section for screen access information.
