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
1. 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 the 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.
2. 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 the Daily Walk Around Inspection.
3. 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.
2.3 DELIVERY AND PERIODIC INSPECTION
NOTE: This machine requires periodic safety and mainte-
nance inspections by a 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.
Periodic inspection shall be performed monthly or more
often when required by environment, severity, and fre-
quency 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.

missing parts; no visible damage.
