that can be fatal, cancer, birth defects, and/or skin
inflammation).
Some dusts and fumes created by drilling, breaking,
hammering, sawing, grinding and other construction
activities contain substances known to the State of
California and other authorities to cause respiratory
disease, cancer, birth defects, or other reproductive
harm. Some examples of such substances are:
>Crystalline silica, cement, and other masonry
products.
>Arsenic and chromium from chemically-treated
rubber.
>Lead from lead-based paints.
Dust and fumes in the air can be invisible to the
naked eye, so do not rely on eye sight to determine
if there is dust or fumes in the air.
To reduce the risk of exposure to dust and fumes,
do all of the following:
►Perform site-specific risk assessment. The risk
assessment should include dust and fumes created
by the use of the machine and the potential for
disturbing existing dust.
►Use proper engineering controls to minimize the
amount of dust and fumes in the air and to
minimize build-up on equipment, surfaces,
clothing, and body parts. Examples of controls
include: exhaust ventilation and dust collection
systems, water sprays, and wet drilling. Control
dusts and fumes at the source where possible.
Make sure that controls are properly installed,
maintained and correctly used.
►Wear, maintain and correctly use respiratory
protection as instructed by your employer and as
required by occupational health and safety
regulations. The respiratory protection must be
effective for the type of substance at issue (and if
applicable, approved by relevant governmental
authority).
►Work in a well ventilated area.
►If the machine has an exhaust, direct the exhaust
so as to reduce disturbance of dust in a dust filled
environment.
►Operate and maintain the machine as
recommended in the operating and safety
instructions

Hydraulic oil
Normally the type of hydraulic oil the carrier is using
also works for the hydraulic breaker. When a
hydraulic breaker is connected to the carrier, the
hydraulic oil will get contaminated faster. Check and
follow the carrier's instructions for changing oil and
oil filter.
It is common to change the oil filter more frequently
when a hydraulic breaker is installed.
NOTICE When the machine is delivered it contains
some mineral based hydraulic oil. Before connecting
to the carrier's hydraulic system, check which type
of hydraulic oil the carrier is using. Mixing different
types of hydraulic oil may destroy the lubrication
quality which can lead to machine damage.
In order to protect the environment we recommend
the use of biologically degradable hydraulic oil.
Viscosity
15-100 cStViscosity (permitted)
Pressure adjustment
To ensure that the accumulator and hammer are not
overloaded, a separate pressure relief valve should
be installed, see picture below. It is set at a value of
30 bar over the hammer’s maximum operating
pressure. If the carrier’s breaker circuit is already
equipped with a pressure limiting valve, no extra
valve is necessary.

Operation
NOTICE The hydraulic breaker or the inserted tool
is not to be used as a lifting device. When lifting
heavy components use the hook on the carrier arm.
Preparation before breaking
Operating temperatures
The operating temperatures of the hydraulic breaker
are between –20 ºC and + 80 ºC.
CAUTION Temperature hazard
The hydraulic breaker and the hydraulic oil system
of the carrier can be damaged if the hydraulic breaker
is used at higher or lower temperatures.
►Only start the hydraulic breaker when the
hydraulic oil has reached the proper operating
temperature.
►If the ambient temperature is below –20 ºC, you
should warm up the insertion tool and the
hydraulic breaker before use.
►If the oil temperature exceeds + 80 ºC, you must
not use the hydraulic breaker as the oil quality
becomes inadequate which severely shortens the
life time of seals and O-rings.
Engine rpm
Too high engine rpm only results in increased fuel
consumption and increased oil temperature. Adapt
the engine rpm to the recommended value to give
the correct operating oil flow.
Operating
Risk area
Before starting the hydraulic breaker, make sure that
no persons are in the risk area, 20 meters both
horizontally and vertically from the hydraulic
breaker.
Breaking
CAUTION Machine and tool hazard
Continuous operation at full extension and/or
retraction can result in damage to the hydraulic
cylinders.
►Always avoid operating the breaker with the
cylinders fully extended or retracted.
►Reposition the carrier and/or boom to avoid fully
extended or retracted cylinders.
►Pay attention and look at what you are doing.

Lubricate the chisel shank thoroughly every two
hours using high-temperature grease such as
genuine chisel grease from your supplier. This also
lubricates the bushing and the tool holder; 5-10
pumps of the grease gun is sufficient. Stop when
the grease starts to emerge at the chisel holder or
between the chisel and the bushing.
WARNING Running engine
If the carrier's engine is running when lubricating
the chisel by hand there is a risk of severe accidents.
►Always switch off the carrier's engine to avoid
accidents.
During lubrication, the chisel must be pressed
against the hammer piston so that the space
between piston and the chisel does not fill with
grease.
WARNING Explosion hazard
Use of other gases than Nitrogen (N2) can cause an
explosion.
►Charge the accumulator with Nitrogen (N2) only!
CP supplies a service box containing all necessary
tools and parts required to service the piston
accumulator. See the Spare parts list.
If the hammer's performance begins to deteriorate,
we recommend that you check the pressure in the
piston accumulator.
NOTICE The pressure must be checked with the
hammer at a working temperature of 60º-70ºC.
To measure the pressure, bring down the hammer
with no pressure on the chisel. Detach the plug from
the charge valve (G) and connect the test pressure
gauge.
The piston accumulator only needs to be filled if the
pressure falls below the minimum level.
Filling
1. Connect pressure relief valve (B) to gas bottle
valve (A).
2. Connect gas hose (C) to pressure relief valve (B)
as shown in figure.
3. Close pressure relief valve (B).
4. Open gas bottle valve (A).
5. Remove the plug from the charge valve (G).
6. Guide the nozzle of the hose (C) into the charge
valve.
7. Carefully open the relief valve (B).
8. Fill the piston accumulator.
9. Read the pressure on the pressure gauge (D).
10. Close the pressure relief valve when the desired
pressure has been reached.
Pull the gas hose out of the charge valve (G) and
fit the plug.

11. Close gas bottle valve (A).
Checking and reducing the gas pressure
1. Always use the gas hose (C) and the pressure
gauge (D) when checking the gas pressure.
2. Connect the gas hose to the pressure gauge.
3. Remove the plug from the charge valve (G).
4. Press the nozzle of the gas hose into the charge
valve and read the pressure.
5. Reduce the pressure by repeatedly inserting and
removing the nozzle.
NOTICE Only the nozzle may be used to reduce
the pressure. Never use pins, screwdrivers etc. as
these can damage the charge valve.
Every second hour
Regularly lubricate the insertion tool, the tool
retainer and the bushings.
Lubricating with a grease gun
WARNING Hot insertion tool during
operation and a period of time after use.
►Avoid contact with the insertion tool.
WARNING Hot hydralic breaker during
operation and a period of time after use.
►Avoid contact with the hydralic breaker.
CAUTION Skin eczema
Grease can cause eczema when it comes in contact
with the skin.
►Avoid getting grease on your hands. Wash
thoroughly after contact.
1. Press the insertion tool against the piston so that
the space between the piston and the insertion
tool does not fill with grease.
2. Lubricate the insertion tool's shank plentifully
while pressing the insertion tool against the
surface to avoid filling the cavity with grease. If
the cavity is filled with grease when the hydraulic
breaker is started, the lower seals may be
damaged.
When the insertion tool shank is exposed to high
pressure and high temperatures a standard type of
grease will melt and run. To avoid this always use a
genuine insertion tool grease from your supplier.
Central lubrication system
We recommend Chicago Pneumatic's central
lubrication system. When this system is fitted on the
carrier, grease is pumped continuosly from a
lubrication container on the carrier to the breaker
when the breaker is activated. This increases the life
of the tool bushings and insertion tools considerably.
