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 ensure 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
NOTE: This machine requires periodic safety and mainte-
nance inspections by an authorized JLG Dealer.
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.
Chassis
1. Check front tire and wheel assemblies for loose or
worn spindles, components and hardware for secu-
rity, tires for wear and damage.
2. Check steering assembly for loose or bent tie rod,
cylinder and hydraulic lines for leaks and security,
and hardware for proper installation.
3. Check rear tire and wheel assemblies for security,
tires for wear and damage.
4. Check drive hubs, hydraulic motors, brakes and
hydraulic lines for damage and leaks.
5. Check oil level in drive hub by removing pipe plug
on side and feeling for oil level. (Contact Service
Personnel for assistance if needed).
NOTE: Torque hubs should be one-half full of lubricant.
6. Check 4WS steering assembly (if equipped) for
loose or bent tie rod, cylinder and hydraulic lines for
leaks and security, and hardware for proper installa-
tion.
7. Check counterbalance, flow divider valves, hydraulic
swivel assembly and lines for visible damage, evi-
dence of leakage, and security and electrical con-
nections for corrosion and tightness.
8. Check extending axle assemblies for evidence of
leakage and security; pressure lines for abnormal
chafing drive hubs, hydraulic motors, brakes and
hydraulic lines for damage and leaks.
