7. 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 mower 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.
8. Start engine and move throttle control ahead to
1/2 throttle position. Disengage parking brake.
A. With the bypass valve open and the engine
running, slowly move the directional control
in both forward and reverse (5 or 6 times).
B. With the bypass valve closed and the engine
running, slowly move the directional control
in both forward and reverse directions (5 to 6
times).
C. It may be necessary to repeat steps A and
B until all the air is completely purged from
the system. When the transaxle operates at
normal noise levels and moves smoothly
forward and reverse at normal speeds, then
the transaxle is considered purged.
Note: Do Not change hydraulic system oil (except
for what can be drained when changing lter), 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.
