Hydraulic System Oil (See FIGURE 19.)
WARNING
At operating temperature the hydraulic oil is HOT. Do
not permit the hot oil to touch the skin and cause a
burn.
CAUTION
Do not permit dirt to enter the hydraulic system when
the oil level is checked or the filter is changed.
Never operate the hydraulic pump without oil in the
hydraulic system. The operation of the hydraulic
pump without oil will damage the pump.
Check the level of hydraulic oil every 250 hours. Heavy
duty or high temperature operations can require more fre-
quent checks.
Check the hydraulic oil level when the oil is at operating
temperature, the carriage is lowered and the engine is
stopped. Add hydraulic oil only as needed. If more hy-
draulic oil is added than the “FULL” level, the hydraulic oil
will leak from the breather during operation. The oil level
indicated by the dipstick is most accurate when the oil
temperature is 53 to 93
°
C (130 to 200
°
F).
Check the hydraulic system for leaks and damaged or
loose components.
