Check Hydraulic Fluid
The hydraulic system is designed to operate on anti–
wear hydraulic fluid. The machines reservoir is filled at
the factory with approximately 12 U.S. quarts (11.4
liters) of Mobil 424 hydraulic fluid. Check level of hy
-
draulic fluid before engine is first started and daily
thereafter.
1. Position machine on a level surface, raise the imple-
ment, and stop the engine.
2. Unscrew dipstick cap from the filler neck and wipe it
with a clean rag. Screw dipstick cap finger tight onto filler
neck. Unscrew the dipstick and check level of oil. If level
is not up to FULL mark on dipstick, add enough oil to
raise level to mark. DO NOT OVERFILL.
3. Screw dipstick filler cap finger–tight onto filler neck.
4. Lower the implement.
