The transmission MUST be in NEUTRAL for proper
installation. A simple check that the NEUTRAL position
has been correctly obtained on operational vehicles and/
or chassis’s is to try and start the vehicle. If the vehicle is
in NEUTRAL it will start, if it is not in NEUTRAL it will not

CAUTION:
When performing this check, make sure that
the vehicle’s emergency brake is set, the
wheels are chocked, and foot pressure is
maintained on the service brake pedal. Failure
to do so may result in injury or death.
