Equipment Lowering with Engine Stopped
Operating techniques – Keep all attachments or
pulled loads low to the ground for optimum stability.
Machine systems have limitations on slopes –
Slopes can affect the proper function and operation
of the various machine systems. These machine
systems are needed for machine control on slopes.
Note: Safe operation on steep slopes may require
special machine maintenance. Excellent skill of
the operator and proper equipment for specific
applications are also required. Consult the Operation
and Maintenance Manual sections for the proper fluid
level requirements and intended machine use.

Equipment Lowering with
Engine Stopped
SMCS Code: 7000
Before lowering any equipment with the engine
stopped, clear the area around the equipment of
all personnel. The procedure to use will vary with
the type of equipment to be lowered. Keep in mind
most systems use a high pressure fluid or air to
raise or lower equipment. The procedure will cause
high pressure air, hydraulic, or some other media
to be released in order to lower the equipment.
Wear appropriate personal protective equipment and
follow the established procedure in the Operation
and Maintenance Manual, “Equipment Lowering with
Engine Stopped” in the Operation Section of the
manual.

Sound Level Information
The operator Equivalent Sound Pressure Level
(Leq) is 81 dB(A) when “ANSI/SAE J1166 OCT 98”
is used to measure the value for an enclosed cab.
This is a work cycle sound exposure level. The cab
was properly installed and maintained. The test was
conducted with the cab doors and the cab 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.
The average exterior sound pressure level is 86
dB(A) when the “SAE J88Feb06 - Constant Speed
Moving Test” procedure is used to measure the value
for the standard machine. The measurement was
conducted under the following conditions: distance of
15 m (49.2 ft) and “the machine moving forward in an
intermediate gear ratio”.
The exterior sound power level is 115 dB(A) when the
value is measured according to the static pressure
test procedures and the conditions that are specified
in “ISO 6393:2008”.

Machines in European Union
Countries and in Countries that
Adopt the “European Union
Directives”
The static operator sound pressure level is 79 dB(A)
when “ISO 6394:2008” is used to measure the value
for an enclosed cab. The test was conducted with the
cab doors and the cab windows closed. The cab was
properly installed and maintained.

Vibration Data for Wheel Scrapers
Information Concerning Hand/Arm Vibration
Level
When the machine is operated according to the
intended use, the hand/arm vibration of this machine
is below 2.5 meter per second squared.
Information Concerning Whole Body Vibration
Level
This section provides vibration data and a method for
estimating the vibration level for wheel scrapers.
Note: Vibration levels are influenced by many
different parameters. Many items are listed below.
