TROUBLES AND ACTIONS
ACTIONS WHEN RUNNING OUT OF FUEL
When starting the engine again after running out of fuel, fill it up with fuel and bleed air from the fuel system
before stating.
Always check the fuel level to prevent running out of fuel.
If the engine has stopped because of running out of fuel, all the air in the fuel circuit must be bled by using the
fuel feed pump.
For the method of bleeding air, see “METHOD FOR BLEEDING AIR FROM FUEL CIRCUIT (4-38)”.
PRECAUTIONS FOR TOWING MACHINE
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.
• If there is a failure in the brake system, the brakes will
not work, so be extremely careful.
NOTICE
• Tow the machine only for a short distance, such as to a place for inspection and maintenance.
Do not tow the machine for a long distance.
• The maximum towing capacity for this machine is 395260 N {40305 kg} .
Do not tow any load greater than this.
• For details of the procedure for towing a disabled machine, consult your Komatsu distributor.
This machine must not be towed except in emergencies. However, if it is avoidable to tow the machine, take the
following precautions.
• When releasing the brake, secure the machine with chocks. If the wheels are not chocked, the machine
may move suddenly.
• When towing a machine, tow it at a low speed of 2 km/h or less, and for a distance of a few meters to a
place where inspection and maintenance can be performed.
This method is applied only in emergencies. If the machine must be moved a long distance, use a trans-
porter.
