CAUTION
Raising the mower deck 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.

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). Check the oil level, and add oil as
required after stopping the engine.
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 the 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 contaminants into the system.

gasoline vapors even after the engine is stopped.
Hot particles exhausted during engine operation
may ignite ammable materials. Fire may result
