PRECAUTIONS FOR OPERATION
• When loading or unloading to an embankment or platform, make sure that it has suitable width, strength,
and grade.
• When swinging the upper structure on the loading platform, lower the work equipment, retract it, and per-
form the operation slowly.
• Always fold the mirrors and stow the radio antenna.
For the method of folding the mirrors and stowing the antenna, see METHOD FOR ADJUSTING MIRRORS
(3-156) and "STOW ANTENNA (3-235)".
For machines equipped with a cab, always lock the door after loading the machine. To prevent the door
from opening during transportation.
For detail, see "TRANSPORTATION (3-236)".
• When it is necessary to remove handrails and steps, take care not to lose removed handrails and steps.
Install the removed handrails and steps securely.

TOWING AND BEING TOWED

PRECAUTIONS FOR TOWING AND BEING TOWED

Always use the correct towing equipment and towing method. Any mistake in the selection of the wire rope or
drawbar or the method of towing a disabled machine and being towed may lead to serious personal injury or
death.
For towing, see "PRECAUTIONS FOR TOWING MACHINE (3-261)".
• Always confirm that the wire rope or drawbar used for towing has ample strength for the weight of the ma-
chine being towed.
• Never use the wire rope which has cut strands (A), re-
duced diameter (B), or kinks (C). There is a danger that
the rope may break during the towing operation.
• Always wear leather gloves when handling the wire rope.
• Never tow a machine on a slope.
• During the towing operation, never stand between the tow-
ing machine and the machine being towed.
LIFTING OBJECTS WITH BUCKET LINK LIFTING DEVICE (OPTIONAL
EQUIPMENT)

SAFETY RULES FOR LIFTING OBJECTS

• Determine the signals to be used and place a signalman in position.
• To prevent the machine from tipping over or falling, carry out the operation on flat ground.
• To prevent the danger of contact with a raised load or the danger from a falling load, do not allow any work-
er inside the area.
• Do not exceed the specified lifting load.
For details of the maximum lifting load permitted for this machine, see the lifting capacity decal and link
markings.
NOTICE
RLL (Rated Lifting Load) for the link may not be the same as the lifting capacity of the machine. Al-
ways be sure to lift within the relevant lifting limits.
• The lifting link RLL (Rated Lifting Load) and part number are stamped on the link as shown below.
• All components in the load line (eg. chains, shackles etc.) must be rated correctly for the load to be lifted.
• When swinging or operating the work equipment, check carefully that the surrounding area is clear from ob-
jects, structures or any persons working around the machine.
