• 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 “STOW ANTENNA (3-236)” and
“METHOD FOR ADJUSTING MIRRORS (3-160)”.
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 (3-237)”.
• 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 (3-258)”.
• 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 OPERATIONS
GENERAL PRECAUTIONS FOR LIFTING OPERATIONS
Falling of a lifted load or tipping over of the machine can cause serious personal injury or death. Always observe
the following.
• Do not perform lifting work on slopes, soft ground, or other places where the machine is not stable.
• Use wire rope that conforms to the specified standard.
• Do not perform any lifting operation with a load heavier than the specified lifting load.
For details of the maximum lifting load permitted for the machine see the decal and lifting equipment manu-
facturers RLL (Rated Lifting Load).
Note: RLL for the bucket may not be the same as the lifting capacity of the machine.
Always be sure to lift within the relevant lifting limits.
For the additional information regarding lifting operations, see “HANDLE BUCKET WITH HOOK (6-13)”.
• Determine the signals to be used and place a signalman in position.
• Prohibit anyone to enter into place where there is danger of contact with a lifted load or the danger from a
falling load.
• It is dangerous if a lifted load hits any person or structure. When operating the swing or work equipment,
always check carefully that the surrounding area is safe.
• Do not start, swing, or stop the machine suddenly. It is dangerous that the lifted load may swing.
