4. Gasoline engine lift truck: Depress the accelerator pedal fully,
then slowly release it. (If the engine is warmed up, there is no need
to depress the accelerator pedal.) With the accelerator pedal
released, turn the starting switch to the START position to start the
engine.
LPG engine lift truck: Open fuel service valve at tank. Turn ignition
switch to START position without depressing the accelerator pedal.
As the engine starts, depress accelerator pedal gently. Do not
depress pedal too far until warmed up.
Diesel engine lift truck: Turn the starting switch to the ON position. When the glow plug lamp goes out, turn
the key to the START position without using the accelerator pedal. Allow the key to return to the ON position
after the engine has started.
5. When the engine starts, release the key. (The key will return automatically to the ON position.)
6. Carry out the warming-up operation as directed below.
Gasoline engine lift truck: Warm up the engine for approximately 1 minute, then depress the accelerator
pedal slightly and release it. If the ambient temperature is high, depress the accelerator pedal lightly after
starting, then release it. The engine speed will go down, and this will make it possible to carry out the warming-
up operation more quietly, and will also save fuel.
LPG engine lift truck: If engine does not start easily, do not "pump" the pedal or hold it open during starting to
avoid damage to the regulator and the engine. Wait for about 2 minutes and retry.
Diesel engine lift truck: Let the engine idle for a full 60 to 90 seconds without using the accelerator pedal.
NOTICE
• Do not run the starting motor continuously for longer than the times given below.

• If the engine does not start, wait for at least 20 seconds (LPG engine - wait 2 minutes) before trying
to start again.
• Do not turn the key to the START position when the engine is running.
22.3.2 TRAVEL INTERLOCK
(OPERATOR PRESENCE SYSTEM)
This is a safety feature of the Operator Presence System. (See
"NEUTRAL/TRAVEL INTERLOCK INDICATOR" on page 3-11 and
"TROUBLESHOOTING THE OPERATOR PRESENCE SYSTEM"
on page 3-12.)
When you operate the lift truck using bad seating posture and your
weight is not fully applied to the seat, such as when standing up or
leaning forward or sideways, Travel Interlock engages within three
seconds and cuts off transmission of engine power. The truck will
not move even if you depress the accelerator pedal or operate the forward/reverse lever. While the Travel Interlock
is engaged, the Travel Interlock indicator lamp on the instrument panel blinks. The lamp doubles as the neutral
lamp.
Return to Travel Condition
Seat yourself properly and return the forward/reverse lever to the neutral position to enable the truck for travel
again. Take this step only after you check the surroundings for safety. Travel Interlock does not brake the truck
forcibly.
