AFTER RUNNING OUT OF FUEL

When starting the engine again after running out of fuel, fill with fuel, then bleed the air from the fuel system before
starting the engine.
Always watch the fuel level and be careful not to run out of fuel.
If the engine has stopped because of lack of fuel, it is necessary to use the priming pump to bleed the air completely
from the fuel circuit.
For details of the method of bleeding the air, see "BLEED AIR FROM FUEL CIRCUIT (PAGE 4-52)".
For details of the poor fuel arrangement specification machines (if equipped), see "BLEEDING AIR FROM FUEL
CIRCUIT WITH THE ELECTRIC PRIMING PUMP (PAGE 4-53)".

METHOD OF TOWING MACHINE

Serious injury or death could result if a disabled machine is towed
incorrectly or if there is a mistake in the selection or inspection of the wire
rope.
If the engine does not start, put blocks under the track to prevent the
machine from moving, then release the brake. If blocks are not used,
there is a danger that the machine may move suddenly.
Always check that the wire rope used for towing has ample strength for
the weight of the machine being towed.
Never use a wire rope which has cut strands (A), reduced diameter (B),
or kinks (C). There is danger that the rope may break during the towing
operation.
Always wear leather gloves when handling wire rope.
Never tow a machine on a slope.
During the towing operation, never stand between the towing machine
and the machine being towed.
Operate the machine slowly and be careful not to apply any sudden load
to the wire rope.
NOTICE
The max. allowable drawbar pull of this machine is 755,110 N (77,000 kg). Do not attempt to pull anything beyond this limit.
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 system, 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 distributor.
Moving a machine by towing is only used to move it to a place where it is possible to carry out inspection and
maintenance. It is not intended for moving the machine long distances. Do not use this method for towing the
machine for long distances.
If it is impossible to operate the steering and brakes of the machine being towed, do not let anyone ride on the
machine.
Keep the angle of the towing line to the minimum. Operate the machine so that the angle does not become
greater than 30 deg. from the straight line.
