Maintenance
Do not rely solely on mechanical or hydraulic jacks for support.
Use adequate jack stands or equivalent support.
Motion Control Lever Linkage Adjustment.
1. Adjustment must be made with the drive wheels turning. Raise the
frame and block so that drive wheels rotate freely.
2. Remove the electric circuit of the seat safety switch under the
seat. Install a jumper wire to the end of the harness connector
temporarily.
3. Run the unit at least 5 minutes with the drive levers at full forward
speed to bring hydraulic system oil up to operating temperature.
4. Start engine. Brake must be engaged and motion control levers out
to start engine. Operator does not have to be in the seat because
the jumper wire is being used. Run engine at full throttle.
NOTE: The motion control lever needs to be in neutral position
while making any necessary adjustments. The left lever controls the
left rear drive wheel, while the right lever controls the right rear drive
wheel.
5. Place the left motion control lever to the neutral position. Loosen
the lock nut on the lever. Rotate the turnbuckle in the middle of
the lever to adjust the length of left hydrostatic transaxle in proper
way until the wheel stops. Pull the lever slightly when it’s in the
neutral position. The motion control lever will rebound to the
neutral position by the reaction power of a spring. The wheels will
stop running or turn back slightly. After doing this, tighten the
lock nut (see Figure 9).
6. Repeat method to adjust length of right motion control lever.
7. Plug in the seat switch.
