3.
Hydraulic and Brake System Oil Filters.
WARNING
DO NOT disconnect or remove any hydraulic system line or fitting unless hydraulic system pressure
has been relieved. Tighten all connections before applying pressure. Escaping hydraulic fluid under
pressure can penetrate the skin, causing serious injury.
Search for leaks with a piece of cardboard. Protect hands and body from high-pressure fluids. If an
accident occurs, see a doctor immediately. Any fluid injected into the skin must be surgically removed
within a few hours or gangrene may result.
At operating temperature, hydraulic oil is hot. Allow hydraulic oil to cool before servicing hydraulic
system. Failure to do so could result in injury.
Hydraulic fluid is very slippery. Immediately wipe up any spills. Failure to follow this warning may
result in injury to personnel.
CAUTION
Following any hydraulic system maintenance action that results in hydraulic system being opened,
replacement of hydraulic reservoir return filters is required after 100 hours of operation.
Replace the hydraulic system and brake system filters at 900-hour intervals.
4.
Front/Rear Axle Differential Housing.
a.
After initial 100 to 200 hours of operation, remove fill/level plug and check level of oil at plug opening. Wait a few
minutes. If oil level falls, add oil until level remains constant.
NOTE
The first time engine oil is changed at 300 hours, front/rear axle differential housing oil must also be
changed. Thereafter, change every 900 hours.
b.
Every 900 hours, drain oil and refill. Place vehicle on level ground and drain oil while it is still warm from opera-
tion. Refill through fill/level plug opening.
5.
Front/Rear Axle Hub End.
a.
After initial 100 to 200 hours of operation, check level of oil in front/rear axle hub ends. Vehicle should be posi-
tioned with drain plug at bottom 6 o'clock position. Oil level should be even with bottom of fill/level plug opening.
NOTE
The first time engine oil is changed at 300 hours, front/rear axle hub end oil must also be changed.
Thereafter, change every 900 hours.
b.
Every 900 hours, drain oil and refill. Place vehicle on level ground and drain oil while it is still warm from opera-
tion. Vehicle should be positioned with drain plug at bottom 6 o'clock position. Refill through fill/level plug open-
ing until level is even with bottom of fill/level plug opening.
6.
Engine Oil and Filter. Replace engine oil and oil filter every 300 hours of operation. Drain oil when engine is warm.
Dispose of used oil properly.
