SECTION A. INTRODUCTION - MAINTENANCE SAFETY PRECAUTIONS
A
GENERAL
This section contains general safety precautions which must
be observed during maintenance of the Mobile Elevating
Work Platform (MEWP). 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 followed to ensure the machine is safe to operate.
MODIFICATION OR ALTERATION OF A MOBILE ELEVATING WORK PLATFORM
SHALL BE MADE ONLY WITH WRITTEN PERMISSION FROM THE MANUFAC-
TURER.
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 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 equip-
ment, ensure 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 the machines hydraulic systems operate at
extremely high potentially dangerous pressures. Every effort
should be made to relieve any system pressure prior to discon-
necting or removing any portion of the system.
