FOREWORD
The purpose of this manual is to provide users with the operating procedures essential for the promotion of
proper machine operation for its intended purpose. It is important to over-stress proper machine usage. All
information in this manual should be READ and UNDERSTOOD before any attempt is made to operate the
machine. YOUR OPERATING MANUAL IS YOUR MOST IMPORTANT TOOL - Keep it with the machine.
REMEMBER ANY EQUIPMENT IS ONLY AS SAFE AS THE OPERATOR.
BECAUSE THE MANUFACTURER HAS NO DIRECT CONTROL OVER MACHINE APPLICATION AND
OPERATION, PROPER SAFETY PRACTICES ARE THE RESPONSIBILITY OF THE USER AND HIS OPERATING PERSONNEL.
ALL INSTRUCTIONS IN THIS MANUAL ARE BASED ON THE USE OF THE MACHINE UNDER PROPER
OPERATING CONDITIONS, WITH NO DEVIATIONS FROM THE ORIGINAL DESIGN. ALTERATION AND/
OR MODIFICATION OF THE MACHINE IS STRICTLY FORBIDDEN, WITHOUT WRITTEN APPROVAL
FROM JLG INDUSTRIES, PER OSHA REGULATIONS.
THIS "SAFETY ALERT SYMBOL" IS USED TO CALL ATTENTION TO POTENTIAL HAZARDS
WHICH MAY LEAD TO SERIOUS INJURY OR DEATH IF IGNORED.
Safety of personnel and proper use of the machine are of primary concern, DANGER, WARNING, CAUTION,
IMPORTANT, INSTRUCTIONS and NOTE are inserted throughout this manual to emphasize these areas.
They are defined as follows:
DANGER INDICATES AN IMMINENTLY HAZARDOUS SITUATION WHICH, IF NOT AVOIDED WILL RESULT IN SERIOUS
INJURY OR DEATH.
CAUTION INDICATES A POTENTIALLY HAZARDOUS SITUATION WHICH, IF NOT AVOIDED, MAY RESULT IN MINOR OR
MODERATE INJURY. IT MAY ALSO BE USED TO ALERT
AGAINST UNSAFE PRACTICES.
Also in this Manual "Notes:" are used to provide information of special interest.
JLG INDUSTRIES, INC. MAY HAVE ISSUED SAFETY RELATED BULLETINS FOR YOUR JLG PRODUCT. CONTACT JLG INDUSTRIES, INC. OR THE LOCAL AUTHORIZED JLG DISTRIBUTOR FOR INFORMATION CONCERNING SAFETY RELATED BULLETINS WHICH MAY HAVE BEEN ISSUED FOR YOUR JLG PRODUCT. ALL ITEMS REQUIRED BY THE SAFETY RELATED
BULLETINS MUST BE COMPLETED ON THE AFFECTED JLG PRODUCT.
WARNING INDICATES A POTENTIALLY HAZARDOUS SITUATION WHICH, IF NOT AVOIDED COULD RESULT IN SERIOUS INJURY OR DEATH.
IMPORTANT OR INSTRUCTIONS PROCEDURES ESSENTIAL
FOR SAFE OPERATION AND WHICH, IF NOT FOLLOWED
MAY RESULT IN A MALFUNCTION OR DAMAGE TO THE
MACHINE.
Due to the continuous product improvements, JLG Industries, Inc. reserves the right to make specification changes without
prior notification. Contact JLG Industries, Inc. for updated information.

INTRODUCTION - MAINTENANCE SAFETY PRECAUTIONS
INTRODUCTION - MAINTENANCE SAFETY PRECAUTIONS
A. GENERAL
This section contains the general safety precautions
which must be observed during maintenance of the aerial
platform. It is of utmost importance that maintenance personnel pay strict attention to these warnings and precautions to avoid possible injury to themselves or others or
damage to the equipment. A maintenance program must
be established by a qualified person and must be followed
to ensure that the machine is safe to operate.
MODIFICATION OF THE MACHINE WITHOUT CERTIFICATION BY
A RESPONSIBLE AUTHORITY THAT THE MACHINE IS AT LEAST
AS SAFE AS ORIGINALLY MANUFACTURED IS A SAFETY VIOLATION.
The specific precautions to be observed during machine
maintenance are inserted at the appropriate point in the
manual. These precautions are, for the most part, those
that apply when servicing hydraulic and larger machine
component parts.
Your safety, and that of others, is the first consideration
when engaging in the maintenance of equipment. Always
be conscious of component weight and never attempt to
move heavy parts without the aid of a mechanical device.
Do not allow heavy objects to rest in an unstable position.
When raising a portion of the equipment, ensure that adequate support is provided.
SINCE THE MACHINE MANUFACTURER HAS NO DIRECT CONTROL OVER THE FIELD INSPECTION AND MAINTENANCE,
SAFETY IN THIS AREA IS THE RESPONSIBILITY OF THE OWNER/
OPERATOR.
C. MAINTENANCE
FAILURE TO COMPLY WITH SAFETY PRECAUTIONS LISTED IN
THIS SECTION COULD RESULT IN MACHINE DAMAGE, PERSONNEL INJURY OR DEATH AND IS A SAFETY VIOLATION.
• REMOVE ALL RINGS, WATCHES, AND JEWELRY
WHEN PERFORMING ANY MAINTENANCE.
• DO NOT WEAR LONG HAIR UNRESTRAINED, OR
LOOSE FITTING CLOTHING AND NECKTIES WHICH
ARE APT TO BECOME CAUGHT ON OR ENTANGLED
IN EQUIPMENT.
• OBSERVE AND OBEY ALL DANGER, WARNING, CAUTION AND OTHER INSTRUCTIONS ON MACHINE
AND IN SERVICE MANUAL.
• KEEP STANDING SURFACES AND HAND HOLDS
FREE OF OIL, GREASE, WATER, ETC.
• NEVER WORK UNDER AN ELEVATED PLATFORM
UNTIL PLATFORM HAS BEEN SAFELY RESTRAINED
FROM ANY MOVEMENT BY BLOCKING OR OVERHEAD SLING.
• BEFORE MAKING ADJUSTMENTS, LUBRICATING OR
PERFORMING ANY OTHER MAINTENANCE, SHUT
OFF ALL POWER CONTROLS.
•BATTERY SHOULD ALWAYS BE DISCONNECTED
DURING REPLACEMENT OF ELECTRICAL COMPONENTS.
• KEEP ALL SUPPORT EQUIPMENT AND ATTACHMENTS STOWED IN THEIR PROPER PLACE.
• USE ONLY APPROVED, NONFLAMMABLE CLEANING
SOLVENTS.
B. HYDRAULIC SYSTEM SAFETY
1. It should be particularly noted that the machines
hydraulic systems operate at extremely high and
potentially dangerous pressures. Every effort should
be made to relieve any system pressure prior to disconnecting or removing any portion of the system.
2. Relieve system pressure by activating the lift DOWN
control with the platform completely lowered to
direct any line pressure back into the return line to
the reservoir. Pressure feed lines to system components can then be disconnected with minimal fluid
loss.

1.5 LUBRICATION
Hydraulic Oil
Hydraulic oils must have anti-wear qualities at least to API
Service Classification GL-3, and sufficient chemical stability for mobile hydraulic system service. JLG Industries,
recommends Mobilfluid 424 hydraulic oil, which has an
SAE viscosity of 10W-30 and a viscosity index of 152.
For cold weather applications, i.e. when temperatures
remain consistently below +20°F (–7° C) JLG recommends using Mobil DTE 13 hydraulic oil.
Aside from JLG recommendations, it is not advisable to
mix oils of different brands or types, as they may not contain the same required additives or be of comparable viscosities. If use of hydraulic oil other than Mobilfluid 424 is
desired, contact JLG Industries for proper recommendations.

MPG - Multipurpose Grease having a minimum dripping point
of 350° F. Excellent wa ter resistance and adhesive qualities, and being of extreme pressure type. (Timken OK
40 pounds minimum.)

1.6 HYDRAULIC PRESSURE ADJUSTMENT
(See Figure 1-1.)
Adjust system pressure so that platform will raise with
rated capacity in platform.
Turning adjustment screw clockwise, increases system
pressure, turning screw counterclockwise, decreases
system pressure.
Do not adjust system pressure higher than required to
raise the load. Make pressure adjustment with oil at normal operating temperature. If pressure is set when oil is

1.8 SERIAL NUMBER LOCATIONS
For machine identification, a serial number plate is affixed
to the machine. The plate is located on the back of the
mast, just above the mast support bracket. In addition,
should the serial number plate be damaged or missing,
the machine serial is stamped on the mast and on the
base frame.
