REPLACING/REPAIRING
•With an operator in the seat, the engine starts but dies soon after the Forward Speed Control (FSC) or PTO is engaged.
•Without an operator in the seat, the engine starts and continues to run with the Forward Speed Control (FSC) and/or PTO engaged.
•With an operator in the seat, the Forward Speed Control (FSC) and PTO disengaged and panel horn works, but the starter is not engaging.
Forward Speed Control Friction Lock
The FSC friction lock is designed to hold the se- lected forward travel speed when the steering le- vers are moved and yet the friction is not too heavy to make moving the FSC control difficult (too much friction). The procedure for checking the FSC fric- tion lock is as follows:
1.Place the FSC in the full FORWARD position and pull both steering levers back; the FSC le- ver should not move. If the FSC lever moves back when the steering levers are pulled 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 lever should move back with a slight amount of resistance (friction). If the FSC lever movement is “stiff”, the friction needs to be decreased.
If the FSC friction lock needs to be adjusted, contact your Walker dealer or refer to the Walker Service Manual.
REPLACING/REPAIRING
dANGER
To prevent accidental starting of the en- gine when replacing parts or repairing the machine, remove the key from the ignition switch and disconnect the spark plug wires.
IMPORTANT: ALWAYS use genuine factory re- placement parts. Substitute parts CAN result in product malfunction and possible injury to the op- erator and/or others.
Drive Belts
There are four (4) individual belts on GHS models:
•Engine PTO Drive Belt (3 Groove Power Band)
•Jackshaft Drive Belt
•GHS Blower Drive Belt
•Hydrostatic Ground Drive Belt
The belts may be removed and replaced using the procedures described on the following pages.
