SECTION A . INTRODUCTION - MAINTE NANCE SAFET Y
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 att ention to these warnings and precau-
tions to avoid po ssible injury to themsel ves or others, or
damage to the equipment. A maint enance program must
be followed to ensure that the machine is safe to operate.
MODIFICATION OF THE MACHINE WITHOUT CERTIFICAT ION 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 maint e-
nance are inserted at the appropriate point in the manual.
These precautions are, for the most part, those that apply
when servicing hydraulic and lar ger machine component
parts.
Your safety, an d that of others, is t he first conside ration
when engaging in the maintenance of equipment. Always
be conscious of weight. Never attemp t to move heav y
parts without the aid of a mechanical device. Do not allow
heavy objects to rest in an unstable posi tion. When raising
a portion of the equipment, ensure that adequate support
is pr ov id e d.
SINCE THE MACHINE MANUFACTURER HAS NO DIRECT CON-
TROL OVER THE FIELD INSPECTION AND MAINTENANCE,
SAFETY IN THIS ARE A 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 e ffort sh ould be mad e to r elieve any syste m
press ure prior to disc onnect ing or remov ing any port ion 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 discon-
nected with minimal fluid loss.
