Safety and operating instructions
Noise hazard
Warning
High sound levels may cause permanent hearing
loss.
Use hearing protection in accordance with
occupational health and safety regulations.
Silica/Dust hazard
Warning
Exposure to crystalline silica (sometimes called
“silica dust”) as a result of breaking, drilling, or
hammering of rock, concrete, asphalt or other
materials may cause silicosis (a serious lung
disease), silicosis-related illnesses, cancer, or
death. Silica is a major component of rock, sand
and mineral ores.
To reduce silica exposure:
Use proper engineering controls to reduce the
amount of silica in the air and the build-up of
dust on equipment and surfaces. Examples of
such controls include: exhaust ventilation and
dust collection systems, water sprays, and wet
drilling. Make sure that controls are properly
installed and maintained.
Wear, maintain, and correctly use approved
particulate respirators when engineering controls
alone are not adequate to reduce exposure
below permissible levels.
Participate in air monitoring, medical exams,
and training programs offered by your employer
and when required by law.
Wear washable or disposable protective clothes
at the worksite; shower and change into clean
clothes before leaving the worksite to reduce
exposure of silica to yourself, other persons,
cars, homes, and other areas.
Do not eat, drink, or use tobacco products in
areas where there is dust containing crystalline
silica.
Wash your hands and face before eating,
drinking, or using tobacco products outside of
the exposure area.
Work with your employer to reduce silica
exposure at your worksite.

Warning
Some dust or other airborne material created
during use of the machine may contain
chemicals known to the State of California
to cause cancer and birth defects or other
reproductive harm. Some examples of such
chemicals are:
Crystalline silica and cement and other masonry
products.
Arsenic and chromium from chemically-treated
rubber.
Lead from lead based paints.
To reduce your exposure to these chemicals,
work in a well ventilated area, and work with
approved safety equipment, such as dust masks
that are specially designed to filter out microscopic
particles.
Vibration hazard
Warning
Repetitive tasks, awkward working positions or
vibrations may cause injury to your fingers, hands,
arms, and other body parts. Exposure to vibrations
may restrict blood supply to the hands and fingers,
which may cause injury. If numbness, tingling,
pain, whitening of the skin, or reduction in feeling
occurs when you use the machine, or even when
you are not using the machine, do not use the
machine and contact a physician.
The inserted tool creates vibrations that may cause
injury. Do not grab, hold, or touch the tool when
using the machine.
Machine modification hazard
Warning
Any machine modification not approved by Atlas
Copco may result in serious injuries to yourself or
others.
The machine must not be modified without Atlas
Copco's permission.
Use only original parts and accessories
approved by Atlas Copco.
