SECTION 2 - PREPARATION AND INSPECTION
SECTION 2. PREPARATION AND INSPECTION
2.1 GENERAL
This section provides the necessary information needed
by those personnel that are responsible to place the
machine in operation readiness, and lists checks that are
performed prior to use of the machine. It is important that
the information contained in this section be read and
understood before any attempt is made to operate the
machine. Ensure that all the necessary inspections have
been completed successfully before placing the machine
into service. These procedures will aid in obtaining maximum service life and safe operation.
SINCE THE MACHINE MANUFACTURER HAS NO DIRECT CONTROL OVER THE FIELD INSPECTION AND MAINTENANCE,
SAFETY IS THE RESPONSIBILITY OF THE OWNER/OPERATOR.
2.2 PREPARATION FOR USE
Before a new machine is put into operation it must be
carefully inspected for any evidence of damage resulting
from shipment and inspected periodically thereafter, as
outlined in paragraph 2-3, Delivery and Periodic Inspection. The unit should be thoroughly checked for hydraulic
leaks during initial start-up and run. A check of all components should be made to assure their security.
All preparation necessary to place the machine in operation readiness status are the responsibility of management personnel. Preparation requires good common
sense, (i.e. lift works smoothly and brakes operate properly) coupled with a series of visual inspections. The mandatory requirements are given in paragraph 2-4, Daily
Walk Around Inspection.
It should be assured that the items appearing in the Delivery and Periodic Inspection and Functional Check are
complied with prior to putting the machine into service.
