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
NOTE: This machine requires periodic safety and mainte-
nance inspections by an authorized JLG Dealer. A
decal located on the frame provides a place to
record (stamp) inspection dates. Check decal and
notify dealer if inspection is overdue.
NOTE: An annual inspection shall be performed on the
aerial platform no later than thirteen (13) months
from the date of the prior annual inspection. The
inspection shall be performed by person(s) qualified
as a mechanic on the specific make and model of
the aerial platform.
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.
This inspection checklist is also applicable and must be
followed for all machines that have been in storage or for
all machines that will be exposed to harsh or changing cli-
mates.
These checks are also to be performed after maintenance
has been performed on the machine.
Chassis
1. Check front tires 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. If equipped with 4WD, check drive hubs, hydraulic
motors, brakes and hydraulic lines for damage and
leaks.
4. Check rear tires and wheel assemblies for security,
tires for wear and damage.
5. Check drive hubs, hydraulic motors, brakes and
hydraulic lines for damage and leaks.
6. 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.
7. Check oscillating axle (if equipped) for loose, miss-
ing and worn parts, pivot pin and lockout cylinder
pins for security, lockout cylinders and hydraulic
hoses for damage and leaks.
