CONTROL PEDALS
The Direction/Speed Pedal (See Fig. 8) controls
speed and direction. Depress front of pedal to go
forward, depress back of pedal to go backward.
Increased movement of the pedal will increase
speed.
To slow and stop the unit, release the pedal
completely. Proper braking is provided by
hydrostatic pressure. If more braking is required,
press on the brake pedal.
WARNING
• DO NOT attempt to force the direction
control pedal to the neutral (stop) position
or to change directions before coming to a
complete stop. Abrupt stops or changes in
direction may cause injury.
