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 Information and

Vibration Information

SMCS Code: 7000

S/N: DBD1-Up

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.

Operator training, behavior, mode, and stress
