The equipment serial number is stamped on the valve body. The model and serial
number are also located on the CE marking. Check that the model corresponds to
the one given on the cover of this manual.
It is important to make correct reference to the serial number of the attachment when
making repairs or ordering spare parts. Identification of the serial number is the only
proper means of maintaining and identifying parts for a specific product.

The product is a hydraulically operated breaker. It can be used on any carrier which
meets the necessary hydraulic and mechanical installation requirements. The unit
functions by repeatedly raising a steel piston and driving it down onto the head of a
removable breaking tool.
No additional pressure accumulators are necessary since the integrated pressure
accumulator absorbs hydraulic pressure peaks. The impact energy of the hammer is
almost constant and independent of the carrier's hydraulic system.
Remove all the steel belts from the package. Open the package and remove all
plastics covering the product.
Recycle all package materials (steel, plastic, wood) properly.
Check that the product is in good condition and that there is no visible damage.
Check that all ordered parts and accessories have been enclosed with the product.
Some options may be provided by your local dealer like installation kits; including
hoses and mounting bracket.
Use a hoist when lifting components which weigh 23 kg (50 lb) or more, to avoid
back injury. Make sure all lifting equipment is in good condition and are in the
correct capacity. Be sure hooks are positioned correctly. Lifting eyes are not to be
side loaded during a lifting operation. Do not use the hammer's tools for lifting.

Use the lifting eyes located on the product housing only to lift or handle the product
itself. The lifting capacity calculation is based on the product's working weight
including a normal working tool and an average sized mounting bracket.
Warning! To avoid falling objects, do not use the product to lift other products.
Use the lifting eyes located on the product housing only to lift or handle the
product itself.
The maximum allowed total weight is shown on the product's CE-plate and
specification page. See “Hammer specifications” on page 66. If the weight exceeds
the maximum allowed total weight shown on the CE-plate and specification page,
you have to use other lifting points/methods than originally provided on the product.
The other threaded holes on the product (for example on the hammer powercell) are
intended for handling single parts only. It is forbidden to lift the entire assembly by
using these threaded holes (for example on the cylinder outer surfaces). For
handling the parts, see product workshop documentation for suitable lifting
methods and lifting adapters.
Tighten the lifting eye screws completely. Put a burden on the lifting eye only if the
screw is properly tightened to the housing.
Failure to properly tighten the screw before allowing load pressure on the
lifting eye may cause lifting eye to break and free fall of the product.
If you use mechanical tools for tightening, make sure not to overstrain the shank.
Before lifting make sure that the rope and/or hook is stretched.
When two lifting eye screws are used, the lifting capacity depends on the angle of
the lifting chains. The angle should not be less than 45°, as shown in the illustration.
When the lifting eye screws are tightened, both rings should be aligned.
The loading capacity calculation applies to temperatures between -10 °C (14 °F)
and 40 °C (104 °F).
Before reuse of lifting eye screws make sure there are no surface flaws (for example
rust, pits, voids, folds and seams, deformation of the ring, or missing or broken
threads).
The local, national safety standards for machines and lifting-equipments must
always be strictly observed.
Note: Before starting to operate the hammer, always replace the lifting eye with a
blanking screw.

Lifting devices must safely carry the working weight of the product. See “Hammer
specifications” on page 66. Place chains or slings, as shown by the illustration, to
lift the product.
Note: Before starting to operate the hammer, always replace the lifting eye with a
blanking screw.

Below are some common safety instructions concerning lifting operations. In
addition to this, the local, national standards for machines and lifting-equipments
must always be strictly observed. Please note that the list below is not all inclusive,
you must always ensure the procedure you choose is safe for you and others.
Do not lift load over people. No one shall be under the hoisted load.
Do not lift people and never ride the hoisted load.
Keep people clear from lift area.
Avoid side pull of the load. Make sure you take up the slack slowly. Start and
stop carefully.
Lift load a few centimeters and verify it before proceeding. Make sure the load
is well balanced. Check for any loose items.
Never leave the suspended load unattended. Maintain load control at all times.
Never lift the load over the rated capacity (see product's operating weight from
specification page).
Inspect all lifting equipment before use. Do not use twisted or damaged lifting
equipment. Protect lifting equipment from sharp corners.
Obey all local safety instructions.

The hammer is equipped with a built-in Ramvalve (check the part number (X) from
the parts manual).
The Ramvalve is designed to decrease oil flow remarkably to the hammer when oil
flow from the carrier is too high.
If the impact rate of the hammer decreases suddenly when operating the hammer,
contact your local carrier dealer to decrease the carrier's oil flow.
The hammer can be equipped with an automatic greasing device. The tool grease is
supplied from the greasing device into the hammer by the grease lines. See
“Automatic greasing” on page 41.
Advantages of the automatic lubrication system are:
Longer service life for wear parts
Higher utilization rate of the hammer
Possibility to grease manually
Reduced grease waste
Note: Some hammer models are equipped with an adapter kit for manual greasing
and do not include an automatic greasing device.

The Ramdata II service indicator system is designed to help the hammer operators
and service personnel get information about the service interval status, service
history and accumulated working history of a hammer. See “Checking the service
interval status” on page 27.
Checking the service interval status

All mechanical equipment can be hazardous if operated without due care or correct
maintenance. Most accidents involving machine operation and maintenance are
caused by failure to observe basic safety rules or precautions. An accident can often
be avoided by recognizing potentially hazardous situations before an accident
occurs.
Because it is impossible to anticipate every possible circumstance that might
involve a potential hazard, the warnings in this guide and on the machine are not all
inclusive. If a procedure, tool, working method or operating technique not
specifically recommended by manufacturer is used, you must satisfy yourself that
it is safe for you and others. You should also ensure that the product will not be
damaged or made unsafe by the method of operation or maintenance procedures you
choose.
Safety is not just a matter of responding to the warnings. All the time you are
working with your attachment you must pay attention to what hazards there might
be and how to avoid them. Do not work with the product until you are sure that you
control it. Do not start any job until you are sure that you and those around you will
be safe.
Warning! Read the following warning messages carefully. They tell you of
different hazards and how to avoid them. If proper precautions are not taken
you or others could be seriously injured.
Study this manual before installing, operating or maintaining the product. If there is
anything you don't understand, ask your employer or your local dealer to explain it.

WARNING
169400_ENG-3

Work sites can be hazardous. Inspect the site before working on it.
Check for potholes, weak ground, hidden rocks and other possible hazards on the
ground. Check for utilities (such as electric cables, gas and water pipes). Mark the
positions of underground cables and pipes if you will be breaking the ground.
Poor visibility can cause accidents and damage. Make sure that visibility and
lighting of the working area are adequate.
Banked material and trenches can collapse. Do not work too close to banks and
trenches where there is a danger of collapse.
Unguarded equipment in public places can be dangerous. Place barriers around the
machine to keep people away.
The related safety label on the hammer and the text on the label are shown below.
"DUST HAZARD
Breathing dust will cause death or severe injury.
Always wear approved respirator."
Airborne pollutants are microscopic particles, which will damage your health, when
inhaled. Airborne pollutants on construction sites can be, for example, silica dust,
oil fumes or diesel exhaust particles, visible or invisible. Especially in demolition
sites, there may be other dangerous substances, such as asbestos or lead paints or
other chemical substances.
DUST HAZARD
Breathing dust will cause death
or severe injury.
Always wear approved
respirator.
DANGER
169400_ENG-1

The effect of airborne pollutants may be immediate if the substance is poisonous.
The main danger with airborne pollutants comes from long term exposure, where
particles are inhaled but not removed from the lungs. The disease is called silicosis,
asbestosis or other, and will result in death or serious injury.
To protect yourself from airborne pollutants, always keep excavator doors and
windows closed during operation. Excavators with pressurized cabins should be
utilized in hammer operation. Proper maintenance of fresh air filters of the
excavator is essential. Where pressurized cabins are not available, proper respirators
must be utilized.
Stop working, when bystanders are in the area of airborne pollutants and make sure
they have proper respirators. Respirators are as important for bystanders as hard
hats.
Respirators for both operator and bystanders must be approved by the respirator
manufacturer for the application in question. It is essential that the respirators
protect from the tiny dust particles which cause silicosis and which may cause other
serious lung diseases. You should not use the equipment until you are sure the
respirators are working properly. This means the respirators must be checked to
make sure that it is clean, that its filter has been changed, and to otherwise make sure
the respirator will protect in the way it is meant to.
Always make sure dust has been cleaned off your boots and clothes when you leave
your shift. The smallest particles of dust are the most harmful. They may be so fine
that you can not see them. Remember, you MUST protect yourself and bystanders
from the danger of breathing or inhaling dust.
Always follow local laws and regulations for airborne pollutants in the working
environment.
The safety label on the hammer is shown below:
"FLYING OBJECTS HAZARD
Fragments fly up to 40 m (130 ft) and could cause death or serious injury.
Stop operation when a person enters hazard zone.
Wear approved personal protective equipment."

Protect yourself and your neighbourhood against flying chips of rock. Do not
operate the product or carrier if someone is too close.
The European standard EN 474-1 on safety of earth-moving machinery requires that
adequate operator's protection, such as bullet proof glass, mesh guard or an
equivalent protection is used.
Keep the cabin windows and doors closed during operation. Window bars are
recommended to protect the windows from flying chips of rock.
A hammer in operation creates a high noise level. Always wear ear protection to
prevent personal injury.
The safety label on the hammer is shown below:
"NOISE HAZARD
