INTERRUPTING THE START ALL PROCESS
Pressing any START/STOP button or turning an ignition key switch during
engine start up is not recommended.
Throttle‑Only Mode
Placing the ERC in throttle‑only mode will avoid unintended gear
engagement. The engines or drives will turn using the steering
wheel or the joystick and the RPM of the engines can be increased
while in throttle‑only mode, but the gear position will remain in
neutral.
To engage throttle‑only mode:
1. Place both ERC levers into neutral.
2. Press THROTTLE ONLY. The throttle‑only light will turn on and the
neutral lights will blink.
3. Place either ERC lever into forward or reverse detent position. The
warning horn will beep each time the levers are moved into or out of gear
while in throttle‑only mode, but the drive will remain in neutral.
