• When connecting the jumper cables, turn the starting switch to OFF position for both the failed machine and
the normal machine. If the failed machine has a battery disconnect switch, turn it to OFF position, and turn
it ON again after connecting the cables.
For details of operation of the battery disconnect switch, see “BATTERY DISCONNECT SWITCH (3-130)”.
It is dangerous that the machine may move when the power is connected.
• Be sure to connect the positive (+) cable first when installing the jumper cables. Disconnect the negative (-)
cable (ground side) first when removing them.
• When disconnecting the jumper cable, take care not to bring the clips in contact with each other or with the
machine.
• For the starting procedure with the jumper cables, see OPERATION, “START ENGINE WITH JUMPER CA-
BLES (3-250)”.
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 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 the operating condition of the machine, work equip-
ment, and travel, braking, steering 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 TRAVELING IN FORWARD OR REVERSE AND SWINGING
• Before operating the travel levers, check the position of the undercarriage.
If the swing axle is positioned at the rear of the machine,
the operation of the F/N/R switch and the steering function
are inverted. In these conditions, pay attention not to con-
fuse the travel movements while using the machine.
• 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 ma-
chine.
• 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.
