SECTION A. INTRODUCTION - MAINTENANCE SAFETY PRECAUTIONS
A. GENERAL
This section contains the general safety precautions which
must be observed during maintenance of the Mobile Elevat-
ing Work Platform. It is of utmost importance that mainte-
nance 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
established by a qualified person and 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 MANUFAC-
TURED IS A SAFETY VIOLATION.
The specific precautions to be observed during machine main-
tenance 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 con-
scious of component weight and 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 rais-
ing 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 IS THE RESPONSIBILITY
OF THE OWNER/OPERATOR.
B. HYDRAULIC SYSTEM SAFETY
1. It should be particularly noted that the machines
hydraulic systems operate at extremely high and poten-
tially dangerous pressures. Every effort should be made
to relieve any system pressure prior to disconnecting or
removing any portion of the system.
2. Relieve system pressure by lowering the platform com-
pletely to direct any line pressure back into the return
line to the reservoir. Pressure feed lines to system com-
ponents can then be disconnected with minimal fluid
loss.
