Explosion and fire hazard,
continued
Warning
Fuel is highly flammable, and it's vapors can
explode if ignited, which can cause serious injury
or death. To reduce such risks of fire or explosion:
Store fuel only in containers that are specifically
designed and approved for storage of fuel.
Empty fuel containers must be properly taken
care of and sent back to the retailer.
Operate the machine with the fuel cap securely
in place. Never remove the fuel cap or add
fuel when the engine is hot. Stop the engine
and allow it to cool before adding fuel. When
opening the fuel cap, always loosen the cap
slowly to relieve any pressure in the tank. Do not
overfill the tank.
Always mix and add fuel in a clean and well-
ventilated area. Make sure that this outdoor
area is free from any flames or sparks. Never
smoke while fuelling, mixing fuel, operating or
servicing the machine. Avoid spilling fuel. Wipe
up any fuel that is spilled on the machine. Fill
the tank at least ten meters (30 feet) away from
where you intend to use the machine.
Do not use a machine that is leaking fuel. Check
regularly for any leakage.
To minimize the risk of fuel leakage during

hazards
Warning
The machine is not electrically insulated. If the
machine comes in contact with electricity, serious
injuries or death may result.
To reduce the risk of injury or death, never
break near any electric wiring or other source of
electricity.
Make sure that there are no concealed wires or
other sources of electricity.
Warning
During breaking or hammering, concealed wires
and pipes constitute a danger that can result in
serious injury.
Before you start breaking, check the
composition of the material you are to work on.
Watch out for concealed electrical wiring, water,
sewage and gas pipes and phone lines.
If the tool seems to have hit a concealed object,
immediately switch off the machine.
Make sure that there is no danger before
continuing.
Projectile hazard
Warning
During breaking or hammering, splinters or other
particles of rock may become projectiles and cause
bodily injury by striking the operator or other

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
Normal and proper use of the machine exposes
the operator to vibration. Regular and frequent
exposure to vibration may cause, contribute to,
or aggravate injury or disorders to the operator’s
fingers, hands, wrists, arms, shoulders and/or
other body parts, including debilitating and/or
permanent injuries or disorders that may develop
gradually over periods of weeks, months, or years.
Such injury or disorder may include damage to the
blood circulatory system, damage to the nervous
system, damage to joints, and possibly damage to
other body structures.
If numbness, tingling, pain, clumsiness, weakened
grip, whitening of the skin, or other symptoms
occur at any time, when operating the machine
or when not operating the machine, do not
resume operating the machine and seek medical
attention. Continued use of the machine after the
occurrence of any such symptom may increase the
risk of symptoms becoming more severe and/or
permanent.
The following may help to reduce exposure to
vibration for the operator:
Let the tool do the job. Use a minimum hand
grip consistent with proper control and safe
operation.
When the percussion mechanism is activated,
the only body contact with the machine you
should have is your hands on the handles. Avoid
any other contact, e.g. supporting any part of
the body against the machine or leaning onto
the machine trying to increase the feed force.
It is also important not to keep the trigger
engaged while extracting the tool from the
broken work surface.
Make sure that the inserted tool is well-
maintained (including sharpness, if a cutting
tool), not worn out, and of the proper size.
Working tools that are not well-maintained, or
that are worn out, or that are not of the proper
size result in longer time to complete a task (and
a longer period of exposure to vibration) and
may result in or contribute to higher levels of
vibration exposure.
Stop working immediately if the machine
suddenly starts to vibrate strongly. Before
resuming the work, find and remove the cause
of the increased vibrations.


