MAINTENANCE
After a few hours use, check all bolts to make sure they are tight.
STEP 1. Regularly inspect the residue manager for loose or worn bolts. Repair and
replace as needed. Use “BLUE” thread lock (removable) if bolts that secure the detent
plate become loose from vibration.
STEP 2 . Lubricate the screw adjust using #2 multi-purpose polyurea grease every 50
hours.
Lubrication
CAUTION: To help prevent serious injury or death to you or others caused by
unexpected movement, service machine on a level surface. Lower machine to
ground or sufficiently lock or block raised machine before servicing. If machine
is connected to tractor, engage parking brake and place transmission in
"PARK", shut off engine and remove key. If machine is detached from tractor,
block wheels and use shop stands to prevent movement.
CAUTION: Do not clean, lubricate, or adjust machine while in motion.
Use grease based on NLGI consistency numbers and the expected air temperature range
during the service interval.
Use a
multi-purpose polyurea, water resistant, moderate speed, and NLGI grade #2
grease.
Other greases may be used if they meet the following
NLGI Performance
IMPORTANT: Some types of grease thickener are not compatible with others.
Consult your grease supplier before mixing different types of grease.
