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,
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 Delivery and Frequent Inspection (see Section
2.3). During initial start-up and run, the unit should be
thoroughly checked for hydraulic leaks. A check of all
components should be made to assure their security.
All preparation necessary to place the machine in opera-
tion readiness status is the responsibility of management
personnel. Preparation requires good common sense,
(i.e. telescope works smoothly and brakes operate prop-
erly) coupled with a series of visual inspections. The man-
datory requirements are given in the Daily Walk Around
Inspection (see Section 2.4).
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 checklist provides a systematic inspection
to assist in detecting defective, damaged, or improperly
installed parts. The checklist denotes the items to be
inspected and conditions to examine.
Frequent inspection shall be performed every 3 months or
150 hours whichever comes first, or more often when
required by environment, severity, and frequency of
usage.
Undercarriage
1. Check the carrier rollers, the track rollers, and the
idler wheels for possible leakage.
2. Check the surface of the track, the carrier rollers, the
track rollers, the idler wheels, the track shoes, and
the drive sprockets. Look for signs of wear and
loose mounting bolts.
3. Listen for any abnormal noises while you are moving
slowly in an open area.
4. If abnormal wear exists or abnormal noises or leaks
are found, consult your JLG dealer.
5. Check oil level in final drive (drive hub) by removing
plug on the side and feeling for oil level. (Contact
Service Personnel for assistance if needed.)
NOTE: Final Drive (drive hub) should be one-half full of
lubricant.
