INTRODUCTION - MAINTENANCE SAFETY PRECAUTIONS

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 per-
sonnel pay strict attention to these warnings and precau-
tions 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 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 CONTROL OVER THE FIELD INSPECTION
AND MAINTENANCE, SAFETY IN THIS AREA RESPON-
SIBILITY OF THE OWNER/OPERATOR.
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.
