CAUTION
POTENTIAL HAZARD
♦ Raising the mower deck for service or
maintenance relying solely on mechanical
or hydraulic jacks could be dangerous.
WHAT CAN HAPPEN
♦ The mechanical or hydraulic jacks may
not be enough support or may
malfunction allowing the unit to fall, which
could cause injury.
HOW TO AVOID THE HAZARD
♦ DO NOT rely solely on mechanical or
hydraulic jacks for support. Use adequate
jack stands or equivalent support.
e) Raise the drive wheels off of the ground and support with jack stands (or
equivalent support) just high enough to allow drive wheels to turn freely.
f) Start engine and move throttle control ahead to full throttle position. Move
the motion control levers to the full speed and run for several minutes.
Shut down machine and recheck oil level.
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.
