Equipment Lowering with Engine
Stopped
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 this system use a high pressure fluid
to raise or lower equipment. The procedure will cause high
pressure hydraulic oil 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.
Sound Level Information
The operator Equivalent Sound Pressure Level is used to
measure a work cycle sound exposure level
Hearing protection may be needed when the machine is
operated with an open operator station for extended periods
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 Data Information
concerning hand/arm vibration
level
When the machine is operated according to the intended
use, the hand/arm vibration of this machine is rated by meter
per second squared.
Note: Vibration levels are influenced by many different
parameters listed below.
Operator training, behavior, mode,
and stress
Job site organization, preparation, environment, weather
and material
Machine type, quality of the seat, quality of the suspension
system, attachments, and condition of the equipment.
Guidelines for Reducing Vibration Levels on Equipment
Properly adjust machines. Properly maintain machines.
Operate machines smoothly. Maintain the conditions of the
terrain. The following guidelines can help reduce the whole
body vibration level:
• Use the right type and size of machine, equipment, and
attachments.
• Maintain machines according to the manufacturer’s
recommendations.
a: Tire pressures
b: Brake and steering systems
c: Controls, hydraulic system and linkages
• Keep the terrain in good condition.
a. Remove any large rocks or obstacles.
b. Fill any ditches and holes.
c. Provide machines and schedule time in order to
maintain the conditions of the terrain.
• Use a seat that meets “ISO 7096”. Keep the seat
maintained and adjusted.
a. Adjust the seat and suspension for the weight and
the size of the operator.
b. Inspect and maintain the seat suspension and
adjustment mechanisms.
• Perform the following operations smoothly.
a. Steer
b. Brake
c. Accelerate
d. Shift the gears
• Move the attachments smoothly.
• Adjust the machine speed and the route in order to
minimize the vibration level.
a. Drive around obstacles and rough terrain.
b. Slow down when it is necessary to go over rough
terrain.
• Minimize vibrations for a long work cycle or a long travel
distance.
a. Haul the machines between workplaces.
• Less operator comfort may be caused by other risk
factors. The following guidelines can be effective in
order to provide better operator comfort:
a. Adjust the seat and adjust the controls in order to
achieve good posture.
b. Adjust the mirrors in order to minimize twisted posture.
c. Provide breaks in order to reduce long periods of
sitting.
d. Avoid jumping from the cab.
e. Minimize repeated handling of loads and lifting of
loads.
f. Minimize any shocks and impacts during sports and
leisure activities.
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
