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 other personnel from coming close to the machine during checks.
• Fasten the seatbelt. 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 that the movement of the machine matches the dis-
play of the control pattern.
• Check the operating condition of the machine, work equip-
ment, and travel and swing systems.
• 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.
PRECAUTIONS WHEN TRAVELLING IN FORWARD OR REVERSE AND SWING-
ING
• When driving the machine, drive with sprocket (1) at the
rear of the machine. If sprocket (1) is at the front, the oper-
ation of the travel levers will be the opposite of the actual
direction of travel, so there is a hazard that the machine
may travel in an unexpected direction, leading to serious
injury or death.
• 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.
• Prohibit anyone other than the operator to get on the machine.
• If there are any people in the area around the machine, there is danger that they may be hit or caught by
the machine, and this may lead to serious personal injury or death. Before starting travel or swing, be sure
to observe the following.
