1. Stop engine, wait for all moving parts to stop, and
remove key. Engage parking brake.
2. Carefully clean area around filter. It is important
that no dirt or contamination enter hydraulic
system.
3. Place a catch pan under the hydro filter.
4. Unscrew filter to remove and allow oil to drain
from filter head.
Important:
Before reinstalling new filter, fill
it with hydraulic oil 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
and Tank Level.

6. Loosen filter 1/2 turn and allow a small amount
of oil to leak from the oil filter (this allows air to
be purged from the oil filter and supply hose from
the hydraulic reservoir). Turn filter clockwise
until rubber seal contacts the filter adapter. Then
tighten the filter an additional 2/3 to 3/4 turn.
7. Remove the catch pan and properly dispose of
hydro oil and filter according to local codes.
8. Raise the rear of machine up and support with
jack stands (or equivalent support) just high

9. Start engine and move throttle control ahead to
full throttle position. Move the speed control
levers to the full speed and run for one minute.
Shut down the machine, allow the hydros to cool
and recheck oil level.
If either drive wheel does not rotate, they may
have lost their “prime”. Refer to
Hydraulic
System Air Purge section.
10. Remove the jack stands.
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.
