GENERAL OPERATING PROCEDURES
STARTING PROCEDURES
Before operating, walk completely around the machine.
Make certain no one is under it, on it or close to it. Let
all other workers and bystanders know you are
preparing to start the machine. DO NOT start machine
until everyone is clear.
To start engine...
1. Be properly seated.
2. Set park brake.
3. Move shift selector to NEUTRAL position. Place
the neutral lock lever to NEUTRAL LOCK
position.
4. Apply brakes.
5. Turn ignition switch clockwise, cranking the
engine. (Do not crank the engine longer than 20
seconds. Wait 2 minutes to allow starter to cool
down before trying again.)
6. Allow engine to warm up.
Note: The transmission requires 3 seconds
immediately after engine start for
self-diagnostics. Always wait at least 3 seconds
after engine start before engaging transmission.
7. In cold weather operation, progressively move
each function a small distance back and forth
until full cycle has been accomplished.
To make sure warm oil reaches the rear carriage
tilt cylinders, slowly raise and lower the boom
several times. Failure to cycle the rear carriage
tilt cylinders during cold machine start-up can
damage the cylinders and structure.
8. Level machine, move frame tilt full to the right,
then full to the left, then back to level.
9. Raise boom full up and full down. Extend inner
boom full out and retract full in.

conditions and adjust your operation of the
forklift accordingly.

the machine.
Always follow these steps:

This is especially important for turbocharged
engines.
