SECTION A. INTRODUCTION - MAINTENANCE SAFETY PRECAUTIONS
A
GENERAL
This section contains the general safety precautions
which must be observed during maintenance of the
mobile elevating work platform. It is of utmost impor-
tance that maintenance personnel pay strict attention
to these warnings and precautions to avoid possible
injury to themselves or others, or damage to the equip-
ment. A maintenance program must be followed to
ensure that the machine is safe to operate.
MODIFICATION OF THE MACHINE WITHOUT APPROVAL BY JLG INDUS-
TRIES, INC. IS A SAFETY VIOLATION.
The specific precautions to be observed during mainte-
nance are inserted at the appropriate point in the man-
ual. 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 weight. 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.
B
HYDRAULIC SYSTEM SAFETY
It should be noted that the machine’s hydraulic systems
operate at extremely high potentially dangerous pres-
sures. Every effort should be made to relieve any system
pressure prior to disconnecting or removing any por-
tion of the system.
Relieve system pressure by cycling the applicable con-
trol several times with the engine stopped and ignition
on, to direct any line pressure back into the reservoir.
Pressure feed lines to system components can then be
disconnected with minimal fluid loss.

MAINTENANCE
FAILURE TO COMPLY WITH SAFETY PRECAUTIONS LISTED IN THIS SECTION
MAY RESULT IN MACHINE DAMAGE, PERSONNEL INJURY, OR DEATH, AND
IS A SAFETY VIOLATION.
• Remove all rings, watches and jewelry when perform-
ing 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 warnings and cautions 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 it has
been safely restrained from any movement by block-
ing or overhead sling, or the safety prop has been
engaged.
• 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.
