SERVICE TRANSMISSION
Check Neutral Creep
NOTE: Check and adjust motion control linkages with the machine
parked on a hard, level surface.
1.Start engine.
2.Set throttle lever to full-throttle position.
3.Unlock the park brake.
4.If the rear drive wheels begin to creep, an adjustment is required.
Neutral Creep Adjustment
1.Stop engine and lock the park brake.
2.Move both motion control levers to neutral detent position (standard
levers) or neutral lock position (optional “over the lap” levers).
3.Raise the rear wheels off the ground and securely support the rear of
the machine.
NOTE: When tilting the seat forward, do not tilt the seat so far
forward that it moves the motion control levers out of the neutral
detent position.
4.Tilt operator seat forward and support the seat frame.
5.Loosen nut (A), and move the dampener (B) in adjusting slot backward
or forward to stop machine creep.
If machine creeps forward, slide dampener to the rear of the adjusting
slot. Tighten nut.
If machine creeps backward, slide dampener to the front of the
adjusting slot. Tighten nut.
6.Check for creep, and if the machine still creeps, continue with the next
step.
7.Remove pin (C) and disconnect swivel (D) from each traction control rod
(E), and rotate the swivel.
8.Rotate swivel (D) to adjust:
To stop forward creep, rotate each swivel (D) counterclockwise one
rotation.
To stop rearward creep, rotate each swivel (D) clockwise one rotation.
9.Connect swivel to traction control rod.
10.Repeat as needed to stop machine creep.
11.Lower seat.
12.Lower the rear of the machine to the ground.
13.Check maximum speed drift.
Check Maximum Speed Drift
1.Check neutral creep, and adjust as needed.
2.Sit on the seat, and start the engine.
3.Operate machine to bring the hydraulic oil to normal operating
temperature.
4.Move the machine in a level, wide-open area, such as an empty parking
lot.
5.Run the engine at full throttle.
6.Move and hold both control levers to the full forward position. Observe
the machine travel. If the machine does not travel in a straight line,
adjustment is required. Note the direction the machine moves.
Maximum Speed Drift Adjustment
1.Park machine safely. (See Parking Safely in the SAFETY section.)
2.Tilt operator seat forward and support the seat frame.
CAUTION: Avoid injury! Engine exhaust fumes contain
carbon monoxide and can cause serious illness or death.
Move the machine to an outside area before running the
engine.
Do not run an engine in an enclosed area without adequate
ventilation.
•Connect a pipe extension to the engine exhaust pipe to
direct the exhaust fumes out of the area.
•Allow fresh outside air into the work area to clear the
exhaust fumes out.
