3. PRODUCT INTRODUCTION
3.1 OVERVIEW
he product is a hydraulically operated breaker. It can be used on all AVAN -carriers
which meet the necessary hydraulic and mechanical installation re-
quirements. he 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. he impact ener-
gy of the hammer is almost constant and independent of the carrier's hy-
draulic system.
3.2 REMOVAL FROM PACKAGE
Remove all the steel belts from the package. Open the package and remove
all plastics covering the product. Recycle all package materials (steel, plas-
tic, wood) properly.
Check that the product is in good condition and that there is no visible dam-
age. 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.
3.3 LIFTING INSTRUCTIONS

4. SAFETY
4.1 GENERAL SAFETY
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 precau-
tions. An accident can often be avoided by recognizing potentially hazard-
ous 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 ma-
chine 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.
War i g! Read the followi g war i g messages carefully. They tell
you of differe t hazards a d how to avoid them. If proper precautio s
are ot take you or others could be seriously i jured.

AIRBORNE POLLUTANTS
he related safety label on the hammer
and the text on the label are shown here.
Airborne pollutants are microscopic
particles, which will damage your health,
when inhaled. Airborne pollutants on
construction sites can be e.g. silica dust,
oil fumes or diesel exhaust particles, visible
or invisible. Especially in demolition sites,
there may be other dangerous substances,
such as e.g. asbestos or lead paints or
other chemical substances.
he effect of airborne pollutants may be
immediate if the substance is poisonous.
he main danger with airborne pollutants
comes from long term exposure, where
particles are inhaled but not removed from
the lungs. he disease is called e.g.
silicosis, asbestosis or other and will result in death or serious injury.
o 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.

FLYING CHIPS OF ROCK
HIGH NOISE LEVEL
13
Safety
hydraulic breaker
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.
his 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 whenyou
leave your shift. he smallest particles of dust are the most harmful. hey
may be so fine that you can not see them. Remember, you MUS 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.
he safety label on the hammer is shown here:
Protect yourself and your neighbourhood against
flying chips of rock. Do not operate the product or
carrier if someone is too close.
he 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.
he safety label on the hammer is shown here:
A hammer in operation creates a high noise level.
Always wear ear protec-tion to prevent personal
injury.

Operating the product beyond its design limits can cause damage. It can
also be dangerous. See Hammer specifications on page 48.
Do not try to enhance the product's performance by unapproved modifica-
tions.
HYDRAULIC FLUID
Fine jets of hydraulic fluid at high pressure can penetrate the skin. Do not
use your fingers to check for hydraulic fluid leaks. Do not put your face close
to suspected leaks. Hold a piece of cardboard close to suspected leaks and
then inspect the cardboard for signs of hydraulic fluid. If hydraulic fluid pen-
etrates your skin seek medical help immediately.
Hot hydraulic fluid can cause severe injuries.
HYDRAULIC HOSES AND FITTINGS
Ensure all hydraulic components will withstand maximum pressure and me-
chanical stresses caused by operation of the attachment. Consult your local
dealer for instructions.
FIRE HAZARD
Most hydraulic fluids are flammable and might ignite when contacting hot
surface. Avoid spilling hydraulic fluid to hot surfaces.
Working with the product on certain materials can cause sparks and hot
splinters to get loose. hese can ignite flammable materials around working
area.
Ensure that adequate extinguisher is available.
HYDRAULIC PRESSURE
Hydraulic fluid at system pressure can injure you. Before disconnecting or
connecting hydraulic hoses, stop the carrier engine, operate the controls to
release pressure trapped in the hoses. During the operation, keep people
away from the hydraulic hoses.
here might be pressurized oil trapped inside the product even if it is discon-
nected from the carrier. Be aware of possible blank firing while greasing or
removing and installing hammer tools. See Changing the tool on page 37.

5. OPERATION
5.1 OPERATING INSTRUCTIONS
RECOMMENDED USE
he hammer is designed to be used in breaking concrete, road surface or
asphalt, hard or frozen ground. It is also suitable for light trenching and
benching applications or in ground compacting. It can be also used in break-
ing small and soft boulders. Your local dealer will gladly give you more infor-
mation.
OPERATING CONDITIONS
Hydraulic oil
In general the hydraulic oil originally intended for the carrier can be used
with this product. See Requirements for hydraulic oil on page 30.
Operating temperature
he operating temperature is -20 °C to 80 °C. If the temperature is lower
than -20 °C, the hammer and tool have to be preheated before any opera-
tions can begin, in order to avoid breaking the accumulator's membrane and
the tool. During operation they will remain warm.
Note: he temperature of the hydraulic oil must be monitored. Ensure that
oil grade and monitored oil temperature together guarantee correct oil vis-
cosity. See Oil specifications on page 31.
PRINCIPLES OF BREAKING
o increase the hammer's working life, pay particular attention to correct
working methods and how to choose the correct tool for the job. here are
essentially two ways of breaking with a hydraulic hammer.
Operation hydraulic breaker
18
Noise dampening
Operating the hammer near residential areas or other noise sensitive areas
can cause noise pollution. In order to avoid unnecessary noise, please follow
these basic rules:
1.When operating with the hammer, keep the tool at 90 degree angle to the
material and the feed force in-line with the tool.
2.Replace or fix all parts that are worn out, damaged or loosened. his not
only saves your hammer but it also decreases the noise level.

Penetrative breaking (or cutting)
In this form of breaking a moil point or chisel tool is forced inside the mate-
rial. his method is most effective in soft, layered or plastic, low abrasive
material. he high impact rate of the small hammers makes them ideal for
penetrative breaking.
CHOOSING TOOLS
Chisel and moil point
lFor sedimentary (e.g. sandstone) and weak metamorphic rock into
which the tool penetrates.
lConcrete.
lrenching and benching.
It is important to choose a tool, which is suitable for your hammer and for the
application you are working on. he tool selection available depend on ham-
mer model. See  ool specifications on page 50.
5.2 DAILY OPERATION
War i g! Protect yourself a d your eighbourhood agai st flyi g
chips of rock. Do ot operate the hammer or carrier if someo e is too
close to the hammer.
The hammer as a sta dard assembly, must ot be used u der water. If
water fills the space where the pisto strikes the tool, a stro g pres-
sure wave is ge erated a d the hammer may be damaged.
War i g! To avoid falli g objects, do ot use Product to lift other prod-
ucts. See Lifti g i structio s o page 7.
19
Operation
hydraulic breaker
Impact breaking
With impact breaking, the material is broken by transferring very strong
mechanical stress waves from the tool into the material. Impact breaking is
most effective in hard, brittle and very abrasive materials. he high impact
energy of the big hammers makes them ideal for impact breaking. he best
possible energy transfer between the tool and the object is achieved with a
blunt tool. he use of a chisel tool in hard material will cause the sharp edge
to wear very quickly.

1. Set the engine speed to the
recommended engine RPM for
correct amount of oil supply.
2. Carefully operate the carrier
controls to place the hammer and
boom into the breaking position.
Quick and careless boom
movements could result in
damage to the hammer.
3. Use the boom to press the
hammer firmly against the object.
Do not pry the hammer with the
boom. Do not press too hard or
too gently with the boom. he
correct force is applied, when the
tires start to lift slightly from the
ground.
4. Place the tool against the object
at a 90 degree angle (see picture
1.). Avoid small irregularities on
the object which will break
easily and cause either idle
strokes or an incorrect working
angle.
5. When demolishing vertical
structures (e.g. brick walls),
place the tool against the wall at
a 90 degree angle.(see picture
2.)
6. Start the hammer.
