An apparatus including an internal combustion engine, an electric motor configured to start the internal combustion engine, a brake mechanism, a release mechanism movable to a first position to release the brake mechanism, a switch actuated by the release mechanism, a pull rope, a sensor configured to output a signal based on the pull rope being actuated, and a control module coupled to the switch and the sensor. The switch is configured to provide a switch input to the control module when the release mechanism is in the first position. The sensor is configured to provide a sensor input to the control module when the pull rope is actuated. The control module activates the electric motor in response to the switch input and the sensor input.
