4.1.10 Service air cleaner:
a) Stop engine, wait for all moving parts to stop, and remove key. Engage
parking brake.

Replace if dirty, bent or damaged.

base around the inner element before removing, so dirt does not get into
the engine.
e) DO NOT wash or use pressurized air to clean paper element or inner
element.
f) Reinstall elements. Position the cover so that the rubber dust ejector is
pointing downward and secure with retaining clips.
4.1.11 Change engine oil:

Place pan under machine to catch oil. Remove plug from end of drain
hose. Allow oil to drain and replace oil drain plug. Torque plug to
20-24 ft-lbs.
d) Replace the oil filter every other oil change. Clean around oil filter and
unscrew filter to remove. Before reinstalling new filter, apply a thin coating of
oil on the surface of the rubber seal. Turn filter clockwise until rubber seal
contacts the filter adapter then tighten filter an additional 2/3 to 3/4 turn.
e) Clean around oil fill cap and remove cap. Fill to specified capacity and replace
cap. Use oil recommended in engine owner's manual. DO NOT overfill.
f) Start the engine and check for leaks.
4.1.12 Check hydraulic oil level:
Service Interval: 40 hr.
a) Stop engine and wait for all moving parts to stop.
b) Unhook seat latch and tilt seat up.
c) Clean area around hydraulic reservoir cap and remove cap. Oil level should
be to the top of the baffle inside the tank. If not, add oil. Use only Mobil 1
15W-50 synthetic motor oil. Replace hydraulic reservoir cap and tighten
until snug. Do not overtighten.
NOTE: The baffle is labeled "HOT" and "COLD". The oil level varies with
the temperature of the oil. The "HOT" level shows the level of oil when it is
at 225°F (107°C). The "COLD" level shows the level of the oil when it is at
75°F (24°C). Fill to the appropriate level depending upon the temperature
of the oil. For example: If the oil is about 150° F (65°C), fill to halfway
between the "HOT" and "COLD" levels. If the oil is at room temperature
(about 75° F (24°C)), fill only to the "COLD" level.
Service Interval: 50 hrs.
More often under severe conditions.
