3. PRODUCT INTRODUCTION
3.1 OVERVIEW
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 ac-
cumulator absorbs hydraulic pressure peaks. The impact energy of the hammer is
almost constant and independent of the carrier's hydraulic system.
3.2 REMOVAL FROM PACKAGE
Remove all the steel belts from the package. Open the package and remove all plas-
tics covering the product. Recycle all package materials (steel, plastic, wood) prop-
erly.
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.
3.3 LIFTING INSTRUCTIONS
Use a hoist when lifting components which weigh 23 kg (50 lb) or more, to avoid
back injury. Make sure all chains, hooks, slings etc., are 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.
Lifting devices must safely carry the working weight of the product. See “Hammer
specifications” on page 54. Place chains or slings, as shown by the illustration, to
lift the product.

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 precautions. An accident can often
be avoided by recognizing potentially hazardous situations before an accident oc-
curs.
Because it is impossible to anticipate every possible circumstance that might in-
volve 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 specifi-
cally 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 work-
ing 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 dif-
ferent hazards and how to avoid them. If proper precautions are not taken you
or others could be seriously injured.

5. OPERATION
5.1 OPERATING INSTRUCTIONS
RECOMMENDED USE
The hammer is designed to be used in breaking oversized boulders, demolishing
heavily reinforced concrete structures and for major heavy excavation and clearing
work. It can be also used for primary breaking, tunnelling and removal of metallur-
gical slag. Your local dealer will gladly give you more information.
OPERATING CONDITIONS
Principle of installation
Almost all carriers meeting mechanical and hydraulic requirements can be used to
operate the attachment. See “Hammer specifications” on page 54. The product is in-
stalled on the carrier much in the same manner as installing a bucket or other attach-
ments. A top mounted attachment requires a separate mounting bracket.
The attachment is connected to a carrier's hydraulic circuit with an installation kit.
If the carrier is already equipped with an installation kit, the installation requires
only suitable hoses and fittings. If the carrier does not have suitable kit to run the
attachment, one must be built. This may require more complex installation includ-
ing new piping and additional valves such as directional valve and pressure relief
valve.
Suitable kits can be ordered from the manufacturer or local dealers, from carrier
manufacturers and their dealers or from third party suppliers.
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 34.
Operating temperature
The operating temperature is -20 °C to +80 °C (-4 °F to +176 °F). If the temperature
is lower than -20 °C (-4 °F), the hammer and tool have to be preheated before any
operations can begin, in order to avoid breaking the accumulator's membrane and
the tool. During operation they will remain warm.
Note: The temperature of the hydraulic oil must be monitored. Ensure that oil grade
and monitored oil temperature together guarantee correct oil viscosity. See “Oil
specifications” on page 35.

Operation S 83 STD
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 mate-
rial and the feed force in-line with the tool.
2. Replace or fix all parts that are worn out, damaged or loosened. This not only
saves your hammer but it decreases the noise level.
PRINCIPLES OF BREAKING
To increase the hammer's working life, pay particular attention to correct working
methods and how to choose the correct tool for the job. There are essentially two
ways of breaking with a hydraulic hammer.
Penetrative breaking (or cutting)
In this form of breaking a moil point or chisel tool is forced inside the material. This
method is most effective in soft, layered or plastic, low abrasive material. The high
impact rate of the small hammers makes them ideal for penetrative breaking.
Impact breaking
With impact breaking, the material is broken by transferring very strong mechanical
stress waves from the tool into the material. The best possible energy transfer be-
tween the tool and the object is achieved with a blunt tool. Impact breaking is most
effective in hard, brittle and very abrasive materials. The use of a chisel tool in hard
material will cause the sharp edge to wear very quickly. The high impact energy of
the big hammers makes them ideal for impact breaking.
CHOOSING TOOLS
A selection of standard and special tools to suit each application are available. The
correct type of tool must be selected to get the best possible working results and
longest life time for the tool. Choosing the best tool type for an application may re-
quire some testing, please consult with your local dealer. See “Tool specifications”
on page 56.

Operation S 83 STD
5.2 DAILY OPERATION
Warning! Protect yourself and your neighbourhood against flying chips of
rock. Do not operate the hammer or carrier if someone is too close to the ham-
mer.
The hammer as a standard assembly, must not be used under water. If water
fills the space where the piston strikes the tool, a strong pressure wave is gen-
erated and the hammer may be damaged.
1. Prepare the carrier for normal excavation work. Move the carrier to the required
position. Set the drive to neutral.
2. Set the engine speed to the recommended engine RPM for correct amount of oil
supply.
3. 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.
