PREPARATION AND INSPECTION
GENERAL PREPARATION
This section provides the personnel responsible for making the machine ready and for its entry in operation with
the information necessary and lists the checks that are to be done before operating the machine. It is important that
the information given in this section is read and understood before using the machine. Ensure that all the necessary
inspections have been done with positive outcomes before using the machine. These procedures have the purpose of
lengthening the working life of the machine and guaranteeing its safety.
IMPORTANT
Since the manufacturer is unable to exercise any direct control over the inspections on the spot and mainte-
nance work, these activities fall under the exclusive responsibility of the owner and the operator.
MAKING READY FOR USE
Before using a new machine it is necessary to inspect it carefully for any evidence of damage sustained during
shipment and then to give it routine inspections as indicated in the section “Inspections to be done routinely and on
receiving the machine”.
During start up and initial operation, the machine must be checked carefully for hydraulic "uid leaks. Check that all
the components are secured in position.
The activities for making the machine ready for use come under the responsibility of personnel in charge. Make ready
requires common sense (for example the telescopic boom should extend and retract without encountering obstacles
and the brakes should work correctly) combined with a series of visual inspections. The compulsory requirements are
listed in the section “Daily visual inspections”.
It is necessary to verify that the directions listed in the sections “Inspections on receipt”, “Routine Inspections” and
“Daily working order check” have been followed.
INSPECTIONS TO BE DONE ROUTINELY AND ON RECEIPT
NOTE
