1.2 DRIVING/TOWING
Before driving the machine, the user must be familiar with
the drive, steer and stopping characteristics. This is espe-
cially important when driving in close quarters.
The user should be familiar with the driving surface before
driving. The surface should be firm and level and grades
should not exceed the allowable grade for the machine.
NOTE: Remember that the key to safe and proper usage is
common sense and its careful application.
The machine is not equipped with provisions for towing.
Refer to Section 6 for emergency towing procedures.
SPECIAL NOTE:
FAILURE TO COMPLY WITH SAFETY PRECAUTIONS LISTED IN

SECTION 2 - PREPARATION AND INSPECTION
3120889 – JLG Lift – 2-1
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 (Section 2.3,
Delivery and Frequent Inspection). 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 (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
NOTE: This machine requires periodic safety and mainte-
nance inspections by an authorized JLG Dealer. A
decal located on the turntable provides a place to
record (stamp)Annual Inspection dates. Check decal
and notify dealer if inspection is overdue.
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 performed after maintenance has
been performed on the machine.
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.
9. Check extending axles for visible damage and loose
or missing parts.
10. 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.

SECTION 2 - PREPARATION AND INSPECTION
2-2 – JLG Lift – 3120889
Turntable
1. Check turntable and turntable lock for damage,
loose or missing parts, and security. Check swing
drive hub, hydraulic motor, and brake for damage,
loose or missing parts, hydraulic lines and compo-
nent housings for evidence of leakage; pinion for
proper mesh with swing gear.
2. Check swing bearing for damage, wear, lubrication
and loose or missing bearing bolts.
3. Check solenoid valves and hydraulic lines for dam-
age, leakage, security and electrical connections for
tightness and evidence of corrosion.
4. Check ground controls for damage, loose or miss-
ing parts, security, electrical connections for evi-
dence of corrosion and tightness and wiring for
insulation damage. Assure that all switches function
properly.
5. Check manual descent valves for visible damage,
evidence of leakage and security. Assure that valves
function properly.
6. Check battery for damage, loose or missing vent
caps, electrical connections for tightness, and evi-
dence of corrosion, holddown brackets for tight-
ness, and electrolyte for proper water level. Add only
clean distilled water to battery.
7. Check engine and accessories for damage, loose or
missing parts, leakage and security. Check throttle
solenoid and linkage for damage, electrical connec-
tions for tightness, and evidence of corrosion and
wiring for insulation damage.
8. Check fuel lines for damage, leakage and security.
9. Check all access doors for damage, proper opera-
tion of latches, props and security.
10. Check fuel tank for damage, leakage and filler cap
for security.
11. Check hydraulic reservoir and hydraulic lines for
damage, leakage and security.
NOTE: JLG recommends replacing the hydraulic filter ele-
ment after the first 50 hours of operation and then
every 300 hours thereafter, unless system indicator
require earlier replacement.
12. Check all cylinder pin and shaft retaining hardware
for security and wear.
13. Check all electrical cables for defects, damage,
loose or corroded connections.
Boom
1. Check all cylinder pin and shaft retaining hardware
for security and wear.
2. Check hydraulic lines, electrical cable and track
assemblies for damage, missing parts and security.
3. Check lift cylinder and cross pins and hydraulic lines

4. Check boom pivot pins for damage, wear, and secu-
rity.
5. Check hydraulic line and electrical cable track
assembly for visible damage, loose or missing parts,
and security.
6. Check boom for damage, missing parts and secu-
rity.
7. Check boom wear pads for damage, wear and secu-
rity.
8. Check boom telescope cylinder and cross pins and
hydraulic lines for damage, wear, leakage and secu-
rity.
9. Check platform leveling cylinder and cross pins and
hydraulic lines for damage, wear, leakage and secu-
rity.
10. Check boom/platform pivot pin for damage, wear
and security.
11. Check horizontal and capacity limit switches
mounted on turntable for security of mounting, dam-
age to switch arms and rollers; and for debris.
12. Check boom tape for correct length, tearing, or
defacing at any point.
Extend-A-Reach (If Equipped)
1. Check the slave cylinder, weld link and cross pins,
and lines for visible damage, wear, lubrication, evi-
dence of leakage, and security.
2. Check extend-a-reach for visible damage, loose or
missing parts, and security.
3. Check hydraulic lines and electrical cable for dam-
age, missing parts and security.
