MAINTENANCE

To avoid personal injury:

A

Be sure to check and service the tractor on a
flat place with the bucket on the ground, engine
shut off, the key removed and the parking
brake on.

LUBRICATION

1. Lubricate all grease fittings every 10 hours of

operation. Also, lubricate joints of control lever linkage
every 10 hours. High quality grease designating
"extreme pressure" and containing Molybdenum
disulfide is recommended. This grease may specify
"Moly EP" on its label.

2. Daily before operation, check the tractor hydraulic fluid

level. If low, add as described in the tractor's operator's
manual. Also change the filter element and the
hydraulic fluid as recommended in the tractor's
operator's manual.
