Maintenance Instructions ADJUSTMENTS

5.If the forward travel is straight throughout the speed range, except at maximum speed - place the FSC in full forward, turn the set screw in the Transmission Control Arm, of the faster side, in until it contacts the hydro stud. (Turning the set screw in slows the wheel.) Turn the set screw in an additional 1/8 turn. Recheck for equal full for- ward speed. Adjust this set screw until equal full forward speed is achieved. Tighten the jam nut.

Forward Speed Control Friction Adjustment - Step 7

FSC Position With Levers

1.Place the FSC in the full forward position and pull both steering levers back; the FSC lever should not move. If the FSC lever moves back the friction needs to be increased.

2.With the steering levers held back, move the FSC lever back from the forward position. With a proper amount of friction adjusted, the FSC le- ver should move back with a slight amount of re- sistance (friction). If the FSC lever movement is "stiff", the friction needs to be decreased.

3.The FSC friction is increased or decreased by tightening or loosening the friction adjustment nut. Loosen or tighten the nut and check the control function until the conditions of both steps 1 and 2 are met.
