Maintenance
4. Unscrew filter to remove and allow oil to drain
from reservoir.
Important:
Before reinstalling new filter, fill
it with Mobil 1 15W-50 and apply a thin coat
of oil on the surface of the rubber seal.
Turn filter clockwise until rubber seal contacts the
filter adapter, then tighten the filter an additional
2/3 to 3/4 turn.
5. Fill reservoir as stated in
Check Hydraulic Oil
Level
section.
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.
7. Start engine and move throttle control ahead to
full throttle position. Move the speed control
levers to the full speed and run for several
minutes. Shut down machine and recheck oil
level.
Note:
Do Not change hydraulic system oil (except
for what can be drained when changing filter), unless
it is felt the oil has been contaminated or been
extremely hot.
Changing oil unnecessarily could damage hydraulic
system by introducing contaminates into the system.
