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 maxi-
mum service life and safe operation.
SINCE THE MACHINE MANUFACTURER HAS NO DIRECT CON-
TROL OVER THE FIELD INSPECTION AND MAINTENANCE, THIS
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 Section 2-3, Delivery and Frequent 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 opera-
tion readiness status are the responsibility of manage-
ment personnel. Preparation requires good common
sense, (i.e. lift works smoothly) coupled with a series of
visual inspections. The mandatory requirements are given
in Section 2-4, Daily Walk Around Inspection.
It should be assured that the items appearing in the Deliv-
ery and Frequent Inspection and Functional Check are
complied with prior to putting the machine into service.
2.3 DELIVERY AND FREQUENT INSPECTION
The following check list provides a systematic inspection
to assist in detecting defective, damaged, or improperly
installed parts. The check list denotes the items to be
inspected and conditions to examine. Frequent inspection
shall be performed every three (3) months or 150 hours,
or more often when required by environment, severity,
and frequency of usage.

Chart” for information on hydraulic oil.
