k k
WARNING
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.
• 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
towing machine and the towed machine.
• Move the machine slowly and be careful not to apply
any sudden load to the wire rope.
• Do not use the holes for towing light objects or tie-
down holes when towing the machine.
NOTICE
The maximum towing capacity for this machine is 42000 N {4280 kg} .
Do not tow any load greater than this.
• If the machine sinks in mud and cannot get out under its
own power, or if the machine tows a heavy object, use a
wire rope as shown in the figure.
• Place pieces of wood between the wire ropes and the ma-
chine to prevent damage to the ropes and the machine.
• Hold the wire rope level and set it straight to the track
frame.
• When towing a machine, travel at a speed of 1 km/h or
less {0.62 MPH or less} for a distance of only a few meters
to a place that is suitable for performing repairs.
This method is applied only in emergencies.
PRECAUTIONS FOR SEVERE JOB CONDITION
• When performing digging operations in water, if the work equipment mounting pin goes into the water, per-
form greasing every time the operation is performed.
• For heavy-duty operations and deep digging, perform greasing of the work equipment mounting pins every
time before operation.
After greasing, operate the boom, arm and bucket several times, then grease again.
