were originally installed at the factory to keep the
fuel line away from components.
Change Auxiliary Hydraulic
Reservoir Fluid
Service Interval: After the first 100 hours
Every 500 hours thereafter
1. Stop engine, wait for all moving parts to stop,
and remove key. Engage parking brake.
2. Carefully clean area around the drain plug and
fill cap. It is important that no dirt or
contamination enter hydraulic system.
3. Unscrew the plug and allow oil to drain.
4. Reinstall the plug and add AW-32 hydro oil
until the level reaches the "cold fill line"
located on the reservoir tank.
Note: Do Not change the hydraulic system
oil unless it is felt the oil has been
contaminated or been extremely hot.
Changing oil unnecessarily could damage
hydraulic system by introducing contaminants
into the system.
Change Hydraulic
Transmission Filter and Fluid
Service Interval: After the first 100 hours
Every 250 hours thereafter
1. Stop engine, wait for all moving parts to stop,
and remove key. Engage parking brake.
2. Locate the two filters under the transmissions.
Remove filter guards.
3. Carefully clean area around filters. It is
important that no dirt or contamination enter
hydraulic system.
4. Unscrew filters to remove and allow oil to
drain from drive system.
Important: Before reinstalling new filters,
apply a thin coat of hydro oil on the surface
of the filters rubber seal.
Turn the filters clockwise until rubber seal
contacts the filter adapter then tighten the
filter an additional 3/4 to 1 full turn.
5. Remove the vent plug on each transmission
and fill through expansion reservoir, when oil
comes out of vent reinstall plug.
Torque plugs to 180 in-lb (244 N-m). Continue
to add Mobil 1 15W-50 synthetic motor oil
until it reaches the FULL COLD line on the
expansion reservoir.
1. Full cold line
6. Raise the rear of machine up and support with
jack stands (or equivalent support) just high
enough to allow drive wheels to turn freely.
CAUTION
Raising the unit for service or maintenance
relying solely on mechanical or hydraulic jacks
could be dangerous. The mechanical or
hydraulic jacks may not be enough support or
may malfunction allowing the unit to fall,
which could cause injury.
Do Not rely solely on mechanical or hydraulic
jacks for support. Use adequate jack stands or
equivalent support.
7. Start engine and move throttle control ahead
to 1/2 throttle position. Disengage parking
brake.
WARNING
Engine must be running and drive wheels
must be turning so adjustments can be
performed. Contact with moving parts or hot
surfaces may cause personal injury.
Keep fingers, hands, and clothing clear of
rotating components and hot surfaces.
A. With the engine running, slowly move the
directional control in both forward and
reverse directions (5 to 6 times). Check the
oil level, and add oil as required after
stopping the engine.
B. It may be necessary to repeat step A until
all the air is completely purged from the
