Throttle Lock Control - The throttle lock control is located on the right side of the operator compartment next to the joystick control. The switch maintains the engine rpm at a desired speed. Engage the switch in order to keep the engine at the current rpm. When the throttle lock is active, an indicator light will illuminate on the front dash. Use the throttle lock control on long hauls in order to avoid driver fatigue. Fatigue may result from depressing the manual governor control for an extended period of time.

On - Push the top of the switch in order to engage the throttle lock control.

Off - To release the throttle lock control, push the bottom of the switch or slightly depress the service brake pedal.
