SECTION A. 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 followed to
ensure that the machine is safe to operate.
MODIFICATION OR ALTERATION OF AN AERIAL WORK PLATFORM SHALL BE
MADE ONLY WITH WRITTEN PERMISSION FROM THE MANUFACTURER.
The specific precautions to be observed during maintenance
are inserted at the appropriate point in the manual. These pre-
cautions are, for the most part, those that apply when servic-
ing 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 con-
scious 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 RESPONSIBIL-
ITY OF THE OWNER/OPERATOR.
B
HYDRAULIC SYSTEM SAFETY
It should be noted that the machines hydraulic systems oper-
ate at extremely high potentially dangerous pressures. Every
effort should be made to relieve any system pressure prior to
disconnecting or removing any portion of the system.
Do not use your hand to check for leaks. Use a piece of card-
board or paper to search for leaks. Wear gloves to help protect
hands from spraying fluid.

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.
• ENSURE REPLACEMENT PARTS OR COMPONENTS ARE
IDENTICAL OR EQUIVALENT TO ORIGINAL PARTS OR
COMPONENTS.
• NO SMOKING IS MANDATORY. NEVER REFUEL DURING ELEC-
TRICAL STORMS. ENSURE THAT FUEL CAP IS CLOSED AND
SECURE AT ALL OTHER TIMES.
• REMOVE ALL RINGS, WATCHES AND JEWELLERY WHEN PER-
FORMING ANY MAINTENANCE.
• DO NOT WEAR LONG HAIR UNRESTRAINED, OR LOOSE-FIT-
TING 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 OIL, GREASE, WATER, ETC. WIPED FROM STANDING
SURFACES AND HAND HOLDS.
• USE CAUTION WHEN CHECKING A HOT, PRESSURIZED COOL-
ANT SYSTEM.
• NEVER WORK UNDER AN ELEVATED BOOM UNTIL BOOM HAS
BEEN SAFELY RESTRAINED FROM ANY MOVEMENT BY
BLOCKING OR OVERHEAD SLING, OR BOOM SAFETY PROP
HAS BEEN ENGAGED.
• BEFORE MAKING ADJUSTMENTS, LUBRICATING OR PER-
FORMING 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 SOL-
VENTS.
