Equipment Lowering with Loss
of Hydraulic Power
Before you lower any equipment with loss of hydraulic
power, clear the area around the equipment of all
personnel. The procedure to lower the equipment will
vary with the type of equipment that is being lowered.
Most systems use high pressure air or fluid to control
the equipment. The procedure may release the
pressure in a high pressure system in order to lower
the equipment. Wear appropriate protective equipment.
Follow the established procedure for lowering
equipment without hydraulic power in the Operation
Section of the Operation and Maintenance Manual.
Sound Information and
Vibration Information
Sound Level
The operator sound pressure level that is measured
according to the test procedure that is specified in "EN
12053:2001" is 80 dB(A) for an enclosed cab. The cab
was properly installed and maintained. The test was
conducted with the doors and the windows closed.
Hearing protection may be needed when the machine
is operated with an open operator station for extended
periods or in a noisy environment. Hearing protection
may be needed when the machine is operated with a
cab that is not properly maintained or when the doors
and windows are open for extended periods or in a
noisy environment.
Vibration Level
The hands and arms are exposed to a weighted root
mean square acceleration that is less than 2.5 m/sec
2
(8.20 ft/sec
2
).
The whole body is exposed to a weighted root mean
square acceleration that is less than 0.5000 m/s
2
(1.70
ft/sec
2
).
The measurements are obtained on a standard
machine. The measurements are obtained by using the
procedures that are in the following standards:
• "ISO 2631-1:1997"
• "ISO 5349-1:2001"
• "SAEJ1166"
Operator Station
Any modifications to the inside of the operator station
should not project into the operator space. The addition
of a radio, fire extinguisher, and other equipment must
be installed so that the defined operator space is
maintained. Any item that is brought into the cab should
not project into the defined operator space. A lunch
box or other loose items must be secured. Objects
must not pose an impact hazard in rough terrain or in
the event of a rollover.
Guards (Operator Protection)
There are different types of guards that are used to
protect the operator. The machine and the machine
application determines the type of guard that should be
used.
A daily inspection of the guards is required in order to
check for structures that are bent, cracked or loose.
Never operate a machine with a damaged structure.
The operator becomes exposed to a hazardous
situation if the machine is used improperly or if poor
operating techniques are used. This situation can occur
even though a machine is equipped with an appropriate
protective guard. Follow the established operating
procedures that are recommended for your machine.
