SAFE TRAVEL
Always observe the following:
Never operate the lift truck from outside the operator's compartment.
Always keep your body under the overhead guard.
Do not extend your arms and legs outside the operator's compartment.
Travel Interlock (power shutdown)/Load Handling interlock
If an operator operates the lift truck without being seated in good posture or
leaves operator's seat during operation, this may cause an accident. To
prevent this, the lift truck is equipped with Travel Interlock (power shutdown)
and Load Handling Interlock functions to disable travel and Load Handling
Interlock functions unless the lift truck is operated in good posture.
During standstill and traveling, if you leave the operator's seat or have bad
posture with no weight applied to the seat during work, the Travel Interlock is
activated about 3 seconds later, shutting off the power of the lift truck. The lift
truck no longer moves even if you operate the accelerator pedal or forward-
reverse lever.
At the same time, the Load Handling Interlock is also activated 3 seconds later during traveling, or one
second later during stand still, disabling all operations of the mast and forks. The lift lever is mechanically
locked out to inhibit operation. Even if the tilt lever or attachment lever is operated, no hydraulic power is
transmitted.
Do not leave operator's seat with the lift lever activated.
If you leave operator's seat with the lift lever turned to the lowering position, the lift truck does not stop
lowering.
Before starting and moving the lift truck, check that the surrounding
area is safe.
Before moving the lift truck, raise the forks (approximately 6 - 8 in.
(15 - 20 cm) from the ground surface), and tilt the mast back.
Before moving the lift truck, release the parking brake.
