Hydraulic fluid escaping under pressure can
penetrate skin and cause injury.
• If hydraulic fluid is injected into the skin
it must be surgically removed within a few
hours by a doctor familiar with this type of
injury. Gangrene may result if this is not
done.
• Keep body and hands away from pin hole
leaks or nozzles that eject high pressure
hydraulic fluid.
• Use cardboard or paper to find hydraulic
leaks.
• Safely relieve all pressure in the hydraulic
system before performing any work on the
hydraulic system.
• Make sure all hydraulic fluid hoses and
lines are in good condition and all hydraulic
connections and fittings are tight before
applying pressure to hydraulic system.
Setting the Hydraulic Pump
Neutral Position
Note: Adjust the handle neutral first. That needs to be
correct before the following adjustment can be made.
This adjustment must be made with drive wheels turning.
Mechanical or hydraulic jacks may fail to
support machine and cause a serious injury.
• Use jack stand when supporting machine.
• Do not use hydraulic jacks.
Engine must be running so motion control
adjustment can be performed. Contact with
moving parts or hot surfaces may cause
personal injury.
Keep hands, feet, face, clothing and other body
parts away from rotating parts, muffler and
other hot surfaces.
1. Raise the frame and block up the machine so 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. Unlatch the seat and slide seat forward.
4. Disconnect the seat rod and tilt the seat fully forward.
Setting the Left-hand Hydraulic Pump
Neutral Position
1. Start the engine, open the throttle 1/2 way and
release parking brake. Refer to Starting and Stopping
the Engine in Operation , page 13.
Note: The motion control lever must be in neutral
while making any adjustments.
2. Adjust the pump rod length by rotating the knob, in
the appropriate direction, until the wheel is still or
slightly creeping in reverse (Figure 57).
3. Move the motion control lever forward and reverse,
then back to neutral. The wheel must stop turning
or slightly creep in reverse.
4. Open the throttle to fast. Make sure wheel remains
stopped or slightly creeps in reverse, adjust if
necessary.
