PREVENTIVE MAINTENANCE
11B-3
SECTION 11B. LUBRICATION AND MAINTENANCE SCHEDULES
GENERAL
This section contains lubrication and maintenance
schedules. Intervals in the lubrication chart, based on
operating hours, can be altered when experience is
gained in machine operation, terrain, and environment.
Over-greasing will produce high loads on bearings and
the engine, resulting in reduced machine performance.
1. Always clean the grease fittings before and after
lubricating.
2. Lubricate with grease that meets or exceeds NLGI
Grade 2 (Service Class LB). Apply grease with a
manual grease gun and fill slowly until grease
begins to seep out. Do not use a compressed air
gun.
3. For smooth operation of levers, pivot points, and
other friction points that are not shown on the
lubrication chart, apply several drops of SAE 30 oil
every 50 hours or as required.
CAUTION
Do not used compressed air grease guns.
WARNING
Before cleaning, adjusting, or repairing the machine,
disengage all drives, lower the decks to the ground,
engage the parking brake, stop the engine, and
remove the ignition key from the ignition switch. Seri-
ous injury can occur if the machine is started while
maintenance is being performed.
