Setting the Hydraulic Pump
Neutral Position
Note: Adjust the handle neutral first. That has to be correct
before you can perform the following adjustment.
Danger
Mechanical or hydraulic jacks may fail to support
the machine and cause a serious injury.
•
Use jack stands when supporting the machine.
•
Do not use hydraulic jacks.
The engine must be running so that you can adjust
the motion control. Contact with moving parts or
hot surfaces may cause personal injury.
Keep your hands, feet, face, clothing and other
body parts away from rotating parts, muffler, and
other hot surfaces.
Warning
You must make this adjustment with the drive wheels
turning.
1. Raise the frame and block up the machine so that the
drive wheels can rotate freely.
2. Disconnect the electrical connector from the seat safety
switch. Temporarily
install a jumper wire across
terminals in the wiring harness connector.
3. Slide the seat forward, disconnect the prop rod and tilt
the seat fully forward.
