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.
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, attachments, and condition of the
equipment.
Guidelines for Reducing Vibration Levels
on Equipment
Properly adjust machines.
Operate machines smoothly. Maintain the conditions of the
terrain. The following guidelines can help reduce the whole
body vibration level:
1. Use the right type and size of machine, equipment, and
attachments.
2. Maintain machines according to the manufacturer's
recommendations.
a. Tire pressures
b. Brake and steering systems
c. Controls, hydraulic system and linkages
3. 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.
4. 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.
5. Perform the following operations smoothly.
22
Properly maintain machines.
a. Steer
b. Brake
c. Accelerate
d. Shift the gears
6. Move the attachments smoothly.
7. 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.
8. Minimize vibrations for a long work cycle or a long travel
distance.
a. Haul the machines between workplaces.
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
equipment with an appropriate protective guard.
Other Guards (If Equipped)
Protection from flying object and/or falling objects is required
for special applications. Logging applications and demolition
applications are two examples that require special protection.
A front guard needs to be installed when a work tool that
creates flying objects is used. Mesh front guards that are
approved by Rayco or polycarbonate front guards that are
approved by Rayco are available for machines with a cab or
an open canopy. On machines that are equipped with cabs,
the windshield should also be closed. Safety glasses are
recommended when flying hazards exist for machines with
cabs and machines with open canopies.
If the work material extends above the cab, top guards and
front guards should be used.
Additional guards may be required for specific applications
or work tools. The Operation and Maintenance Manual
for your machine or your work tool will provide specific
requirements for the guards. Consult your Rayco dealer for
additional information.
