Reset stop lever by hand.

Operators, once the EMERGENCY ENGINE STOP lever is pulled on your M939/AI truck, you won't be able to restart it until the hood is raised and the fuel cutoff valve is manually reset.

You're fooling yourself if you think it's just a matter of pushing the EMERGENCY ENGINE STOP lever back in. You'll just keep cranking an engine that won't start. That drains the batteries and can burn up the starter.

Remember that the EMERGENCY ENGINE STOP lever is for emergencies only. Use both the battery ON/OFF switch and the START/RUN/OFF switch to shut down the engine under normal conditions.

Shutdown procedures should be closely followed on all M939's equipped with antilock braking system (ABS). Otherwise, the electronic control unit (ECU) may be damaged, faults created, and the ABS valves will stop working. Turn the vehicle light switch off and turn the ignition switch to the OFF position. Then wait for the engine to completely stop before turning the battery switch to the OFF position.

If you must use the lever, call in your mechanic to reset it and check out the problem before trying to start the engine again.
