after confirming that the machine's surroundings
are clear of personnel and obstructions.
• Always start the engine from the operator seat.
Never start the engine by shorting the starter
solenoid or starter relay.
• Never use ether starting fluid to start the engine.
Ether is highly flammable and can cause a fire or
an explosion that could result in death or serious
injury.
• Exhaust gas contains carbon monoxide. Carbon
monoxide is an invisible and odorless gas.
Carbon monoxide is toxic and could cause death
or serious injury. Provide adequate ventilation
when starting the engine in a confined space.
Failure to follow these warnings could result in
death or serious injury.
