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 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 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 maintenance
are inserted at the appropriate point in the manual. These pre-
cautions are, for the most part, those that apply when servic-
ing 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 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 RESPONSIBIL-
ITY OF THE OWNER/OPERATOR.
B HYDRAULIC SYSTEM SAFETY
It should be noted that the machines hydraulic systems oper-
ate at extremely high potentially dangerous pressures. Every
effort should be made to relieve any system pressure prior to
disconnecting or removing any portion of the system.
Do not use your hand to check for leaks. Use a piece of card-
board or paper to search for leaks. Wear gloves to help protect
hands from spraying fluid.
