PRECAUTIONS FOR OPERATION
CHECKS BEFORE OPERATION
If the checks before starting are not performed properly, the machine will be unable to display its full perform-
ance. It is dangerous and may cause serious personal injury or death.
When performing the checks, move the machine to a wide area with no obstructions, and pay careful attention
to the surroundings. Prohibit anyone other than the operator from coming close to the machine during checks.
• Fasten the seat belt. When the brakes are applied sudden-
ly, the operator may be thrown out of the operator's seat. It
is dangerous and may cause personal injury.
• Check the operation of travel, steering and brake systems,
and dump body control system.
• Check for any problem in the sound, vibration, heat and
smell of the machine, or abnormalities of instruments. Also
check that there is no leakage of oil or fuel.
• If any problem is found, repair it immediately.
• Before starting to drive the machine or perform operations,
check that articulation lock (1) is fixed securely at FREE
position.
PRECAUTIONS WHEN TRAVELING IN FORWARD OR REVERSE
• Always lock all the doors and windows of the operator's compartment in position regardless of whether it is
open or closed.
Always close all the windows and doors on jobsites where there is danger of scattering fragments, and
things which may intrude into operator's cab.
• If another person is allowed on the machine, that person may sit only in the assistant's seat.
• If there are any persons in the area around the machine,
there is danger that they may be hit or caught by the ma-
chine, and this may lead to serious personal injury or
death. Always observe the following before traveling.
• Always operate the machine only when seated on the
operator's seat.
• Before starting to move, check again that there is no
people or obstacle in the surrounding area.
• Before moving, sound the horn to warn people in the
surrounding area.
• Check that the backup alarm (alarm buzzer when machine travels in reverse) works properly.
• If there is an area in the rear of the machine which cannot be seen, allocate a conductor.
Always be sure to perform the above precautions even when the machine is equipped with mirrors and cam-
eras.
