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.
