GENERAL
This section contains the general safety precautions
which must be observed during maintenance of the
crane 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 established by a qualified person
and must be followed to ensure that the machine is
safe to operate.
WARNING: MODIFICATION OF MACHINE
WITHOUT CERTIFICATION BY A
RESPONSIBLE AUTHORITY THAT THE
MACHINE IS AT LEAST AS SAFE AS
ORIGINALLY MANUFACTURED IS A SAFETY
VIOLATION.
The specific precautions to be observed during ma-
chine maintenance are inserted at the appropriate
point in the manual. These precautions are those that
apply when servicing hydraulic and larger machine
component parts.
The safety of the maintenance and operating person-
nel must be 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.
WARNING: SINCE MACHINE
MANUFACTURER HAS NO DIRECT
CONTROL OVER FIELD INSPECTION AND
MAINTENANCE, SAFETY IN THIS AREA IS
THE RESPONSIBILITY OF THE OWNER/
OPERATOR.
HYDRAULIC SYSTEM SAFETY
It should be particularly noted that the machine’s
hydraulic systems operate at extremely high and
potentially dangerous pressures. Every effort should
be made to relieve any system pressure prior to dis-
connecting or removing any portion of the system.
Relieve system pressure by moving the boom control
levers several times with the engine stopped and
ignition on to direct any line pressure back into the
return line and to the reservoir. Pressure feed lines to
system components can then be disconnected with
minimal fluid loss.
