WARNING!
•
Before starting the engine or leaving the operator seat, make sure the hydraulic lockout
control lever is in the locked (closed) position. If the hydraulic system is not locked,
unintentional machine operation may occur.
•
Confirm that the surrounding area is clear of personnel and obstructions, and sound the
horn before starting the engine.
•
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.
•
Exhaust gas contains carbon monoxide. Carbon monoxide is an invisible and odorless
gas, and is toxic. Provide adequate ventilation when starting the engine in a confined
space.
Failure to follow these warnings could result in death or serious injury.
NOTICE!
Before starting the engine, make sure that the throttle control dial is at MIN (low idle). Starting
the engine with the throttle control dial at MAX (high idle) will accelerate the engine and could
cause damage.
