TROUBLES AND ACTIONS
ACTIONS WHEN RUNNING OUT OF FUEL
When starting the engine again after running out of fuel, fill with fuel until the fuel level caution lamp on the ma-
chine monitor goes out, then bleed the air from the fuel system before starting the engine.
Always check the fuel level to prevent running out of fuel.
If the engine has stopped because of running out of fuel, all air must be bled from the fuel circuit by using fuel
feed pump.
The injection pump and nozzles used on the engine of this machine consist of more precise parts than
those in the conventional ones. If there is any foreign material, it may cause a trouble. If dust sticks to
the fuel system, wash it off thoroughly with fuel.
For air bleeding method, see MAINTENANCE, "METHOD FOR BLEEDING AIR FROM FUEL CIRCUIT".
PRECAUTIONS FOR TOWING MACHINE
k
k
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.
•
If the engine does not start, block the tracks from
movement, then release the brake. If blocks are not
used, there is a danger that the machine may move
suddenly.
•
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.
•
Wear the leather gloves always when handling the wire
ropes.
•
Never tow a machine on a slope.
•
During the towing operation, never stand between the
towing machine and the machine being towed.
•
Move the machine slowly.
Do not apply a sudden load to the wire rope.
NOTICE
The maximum towing capacity for this machine is 475620 N {48500 kg} .
Do not tow any load greater than this.
For details of the method of towing, contact your Komatsu distributor.
•
If the engine stops or the oil pressure in the brake circuit lowers because of a trouble in the hydraulic sys-
tem, the brake works and the machine cannot move. To move the machine in this case, the oil pressure in
the brake circuit must be heightened to the specified level with a special device. Contact your Komatsu dis-
tributor.
