OPERATIONS IN CASE OF FAILURE

3.14.2 REMOVING THE MACHINE IN CASE OF FAILURE
DANGER
• The removal of a machine in case of failure always involves risks that may cause injuries to the persons
responsible for this type of operation.
• The machine can be moved only with the boom completely retracted and lowered.
• Before attempting to remove the machine, decide the travel direction or the coupling points of the tow-
ing cable or bar.
• To remove the machine, use metal cables or a rigid bar with resistance suitable for towing weights equal
to or more than 1.5 times the weight of the machine as specified on the identification plate.
If the machine to be towed is positioned downhill, use only a strong rigid bar, in such a way as to be able
to control the brakes in total safety.
• The vehicle that will remove the machine must have at least the same dimensions as the machine to be
towed and its power, weight and braking capacity must be sufficient to stop both vehicles.
• Before coupling the towing vehicle and before releasing the parking brake, block the machine with
wedges.
• Install metal guards on the two vehicles (towing vehicle and problem machine), in order to protect their
drivers from the impacts due to any breakage of the bar or towing cables.
• If you are not sure about the manoeuvres to be carried out or if the problems to which the failure is due
cannot be solved with routine maintenance, contact your Komatsu Utility Dealer.
1 - Only the operator can get on the problem machine, and only if the service brakes are functioning and steering
is possible.
ATTENTION
• If the failure involves the engine, there is no hydraulic pressure for the power-assisted braking and
steering pumps; this makes the operations very hard. The amount of effort required to operate the
brakes and the steering wheel will be much greater than in normal conditions and this will slow down re-
sponse time considerably.
2 - Couple the cable or the bar only to the points indicated and
ask an Assistant to supervise the various manoeuvres; the
Assistant must be the only reference person for the interrup-
tion of the recovery operations in case of danger.
3 - Tow the machine only with slow movements and parallel trac-
tion, or with a maximum inclination of 20° with respect to the
axis of the machine.
4 - Disengage the parking brake and remove the wedges from
the wheels only when the cable or bar are tensioned.
3.14.3 IF THE FUEL HAS RUN OUT
If the engine stops because the fuel has run out, proceed as follows:
1 - Refuel.
2 - Bleed the fuel supply circuit.
For further details, see paragraph «4.7.8 MAINTENANCE EVERY 500 HOURS OF OPERATION OR EVERY
6 MONTHS» in the maintenance section.
