OPERATION

METHOD FOR LIFTING OBJECTS WITH LIFTING DEVICE

• The excavator used in handling operations must conform with current local regulations and be
equipped with safety valves and an overload alarm in compliance with EN 474-5.
• The owner and operators must be familiar with all legal guidelines and regulations that govern the
use of the equipment both as an earth moving machine and as a load handling machine. Ask your
Komatsu distributor for further information.
• The machine must be equipped with an appropriate lifting hook, otherwise it cannot be used for
handling loads.
In the absence of such a device, the machine can only be used as an earth moving machine.
If the machine is not equipped with an appropriate hook, contact the Komatsu distributor.
Fitting a lifting hook must be monitored and certified by the competent Authorised Body.
• Only the hook situated on the rod of the bucket should be used as a coupling point for the purpose
of lifting objects. Do not use other coupling points.
• It is forbidden to weld hooks or ears to the bottom of the bucket.
• It is absolutely forbidden to move the machine with the load suspended as the load may oscillate
and pose a risk to objects and persons, as well as to the machine itself.
• Place the machine on a firm and level place.
• Ensure that the work area is free from obstacles and that there are no persons in the operational range of
the machine and signal the beginning of the working operation by sounding the acoustic alarm.
• Select work mode L. For details see "METHOD FOR SELECTING WORKING MODE (3-198)".
• Ensure that the lifting hook and the load handling cables are of sufficient dimensions to handle the load to
be lifted, and that they are equipped with an effective anti-release device.
• Use the commands gently and progressively in order to maneuvre the load movement with precision.
• Always maintain the load as close as possible to the ground so as to be able to lay it down quickly in the
event that the slightest instability of the load or of the machine is detected.
• After having positioned the load, uncouple it.
•
NOTICE
When the machine reach its load limit the acoustic alarm
and the overload alarm light will indicate this fact. For de-
tails, see "OVERLOAD CAUTION LAMP (3-30)".
LIFTING CAPACITIES TABLES
