SECTION A. INTRODUCTION - MAINTENANCE SAFETY
PRECAUTIONS
A
GENERAL
This section contains the general safety precautions which
must be observed during maintenance of the aerial plat-
form. It is of utmost importance that maintenance person-
nel pay strict attention to these warnings and precautions
to avoid possible injury to themselves or others, or dam-
age to the equipment. A maintenance program 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 VIOLA-
TION.
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 pressures.
Every effort should be made to relieve any system pres-
sure prior to disconnecting or removing any portion of the
system.
Relieve system pressure by cycling the applicable control
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.
