WHEEL DRIVE NEUTRAL ADJUSTMENT 

 

 

The speed control cables may need to be adjusted after some use. If the machine creeps 
while the speed control is in neutral, the speed cables will need adjustment. Adjust the 
cables to bring the pump cable arm to the neutral position (vertical) when the speed control 
also is in neutral. Adjust the cables to eliminate slack, but do not over tighten them so they 
are extremely tight against each other.
