SECTION A. INTRODUCTION - MAINTENANCE SAFETY
PRECAUTIONS
A. GENERAL
This section contains general safety precautions which
must be observed during aerial platform maintenance. 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 machine is safe to operate.
MODIFICATION OR ALTERATION OF AN AERIAL WORK PLAT-
FORM SHALL BE MADE ONLY WITH WRITTEN PERMISSION
FROM THE MANUFACTURER.
The specific precautions to be observed during mainte-
nance 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 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 CON-
TROL OVER THE FIELD INSPECTION AND MAINTENANCE,
SAFETY IN THIS AREA RESPONSIBILITY OF THE OWNER/OPER-
ATOR.
B. HYDRAULIC SYSTEM SAFETY
It should be noted that the machines 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 portion of
the system.
