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
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.

what you will be doing. If you will be working with other people make sure they
understand any hand signals you will be using.
Work sites can be noisy. Do not rely only on spoken commands.
WORK SITE
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.
BANKS AND TRENCHES
Banked material and trenches can collapse. Do not work too close to banks and
trenches where there is a danger of collapse.

169410_ENG-1
R010349
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.
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.

5.1 OPERATING INSTRUCTIONS
RECOMMENDED USE
The 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 breaking small and soft
boulders. 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 56. The product is
installed on the carrier much in the same manner as installing a bucket or other
attachments. A flange mounted attachment requires a separate mounting bracket.
If the carrier has already auxiliary hydraulic circuit, 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 installation including new piping
and additional valves such as directional valve and pressure relief valve.
Suitable kits can be ordered from the 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 37.
Operating temperature
The operating temperature is -20 °C (-4 °F) to 80 °C (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 38.
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.

1322 STD
2. Replace or fix all parts that are worn out, damaged or loosened. This not only
saves your hammer but it also 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.
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
require some testing, please consult with your local dealer. See “Tool
specifications” on page 58.
Chisel and moil point
■ For sedimentary (e.g. sandstone) and weak metamorphic rock into which the
tool penetrates.
■ Concrete.
■ Trenching and benching.
Blunt tool
■ For igneous (e.g. granite) and tough metamorphic rock (e.g. gneiss) into which
the tool doesn't penetrate.
■ Concrete.
■ Breaking boulders.
Spade tool
■ Frozen or compact ground.
■ Asphalt.
Compacting plate
■ Ground compacting.
It is important to choose a tool, which is suitable for your hammer and for the
application you are working on. The tool selection available depend on hammer
model. See “Tool specifications” on page 58.

5.2 DAILY OPERATION
GENERAL GUIDELINES
-
A safety screen is recommended to protect the operator from flying debris.
Keep the cabin windows and doors closed during operation.
-
Keep the tool at a 90 degree angle at all times. If the object moves or its surface
breaks, correct the angle immediately. Keep the feed force and tool aligned.
-
Keep the tool shank well greased during operation. Regular visual inspections
during operation are recommended. An unlubricated tool shank requires more
frequent greasing intervals. A tool shank covered with excessive grease
requires less frequent greasing intervals.
-
To use the hammer most efficiently when breaking, concentrate on small steps

Operation - Page 23
Operation
1322 STD
from the outer edge towards the middle.
-
Do not strike in one spot for more than 15 seconds at a time. If the object does
not break, or if the tool does not penetrate, stop the hammer and change the
position of the tool. Working too long in one spot will create stone dust under
the tool. Dust dampens the impact effect and produces heat.
-
Listen to the hammer's sound when you are using it. If the sound becomes
weaker and the impact less efficient, the tool is misaligned with the material
and/or there is not enough down force on the tool. Realign the tool and press the
tool firmly against the material.
-
Do not let the tool move outwards from the hammer when it penetrates. Keep
the down-pressure on the hammer while breaking.
-
When demolishing vertical structures (such as brick walls), place the tool

1322 STD
Operation
against the wall at a 90 degree angle.
-
When breaking concrete, hard or frozen ground, never strike and pry with the
tool at the same time. The tool may break. Bending may be caused by stones
inside hard or frozen ground. Be careful and stop striking if you find sudden
resistance under the tool.
-
When breaking hard or frozen ground, use the benching method. Start with
clearing a small area from the edge. Then continue by breaking material
towards the open area.
-
When operating the hammer, make sure that it does not make contact with the

1322 STD
carrier boom or hydraulic lines.
-
Do not operate the hammer with the carrier's boom stick or bucket cylinders at
the end of their stroke (either fully extended or retracted). Damage to the carrier
may result.
-
Do not use the hammer to sweep the ground of debris. This may damage the
hammer and the housing will wear out more quickly.

-
Do not use the hammer or hammer tools for lifting. Lifting eyes on the hammer
are for storage and maintenance purposes only.
WORKING PROCEDURE
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
hammer.
Do not use the hammer, as a standard assembly, under water. If water fills the
space where the piston strikes the tool, this generates a strong pressure wave
that may damage the hammer.
Warning! To avoid falling objects, do not use the product to lift other products.
See “Lifting instructions” on page 8.
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.

Operation
1322 STD
3. Carefully operate the carrier controls to place the hammer and boom into the
breaking position. Quick and careless boom movements can result in damage to
the hammer.
4. Use the excavator 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. The force is correct when the tracks start to lift slightly from the ground.

Operation
5. Place the tool against the object at a 90 degree angle. Avoid small irregularities
on the object which will break easily and cause either idle strokes or an
incorrect working angle.
6. Start the hammer.
7. Stop the hammer quickly. Do not allow the hammer to fall down and make idle
strokes when an object breaks. Frequent idle strokes have a deteriorating effect
on the hammer. If the hammer falls through, the housing wears out more
quickly.

removal!
Warning! Hydraulic pressure inside the hammer must always be released
before opening hose connections!
Warning! Hot hydraulic fluid can cause severe injuries!
1. Position hammer horizontally on the floor. If the hammer is going to service,
remove the tool.
2. Stop the carrier engine. Operate boom and hammer controls to release pressure
trapped inside hoses. Wait ten minutes for oil pressure to drop.
3. Close hammer inlet and outlet lines. If quick couplers are used, disconnection
automatically closes hammer lines. If hammer line includes ball valves, please
make sure that they are closed.
4. Disconnect hoses. Protect environment from oil spills. Plug the hoses and the
hammer inlet and outlet ports.
5. Remove bucket pins and other parts.
6. The carrier can be moved aside.
INSTALLATION
1. Install hammer in the same manner as mounting a bucket. Install bucket pins.
2. Connect hoses. Hammer inlet port is marked on the valve body with "IN" and

Hammer tool greasing
1.2 MANUAL GREASING
Follow the product's greasing instructions and avoid excessive greasing.
Dispose of empty grease containers appropriately.
GREASING INTERVAL
1. Tool shank must be well lubricated before installing tool.
2. 5-10 strokes from grease gun to tool bushings and tool at regular intervals.
3. Adapt interval and amount of grease to wear rate of tool and working
conditions. This can be anything between two hours and daily, depending on
material (rock/concrete) to be broken. See “Recommended greases” on page 34.
Insufficient greasing or improper grease may cause:
■ Abnormal wear of tool bushing and tool
■ Tool breakage
CORRECT GREASING
1. Position the hammer standing upright resting on the tool on firm surface.
2. Stop carrier engine and wait 10 minutes for oil pressure to drop inside hammer.
3. Apply tool grease from grease gun to greasing points marked with the following
sticker.
Note: The hammer must stand upright resting on the tool to ensure that the grease
will penetrate downwards between the tool and the bushing.

Carrier hydraulic oil
2. CARRIER HYDRAULIC OIL
2.1 REQUIREMENTS FOR HYDRAULIC OIL
GENERAL REQUIREMENTS
In general the hydraulic oil originally intended for the carrier can be used with this
product. However, since working with the product heats the oil more than the usual
excavation work, the temperature of the oil must be monitored.
If the temperature of the hydraulic oil exceeds 80 °C (176 °F), an auxiliary oil cooler
is needed. The oil viscosity must be between 20-1000 cSt while the attachment is
being used.
When the product is used continuously, the temperature of the hydraulic oil
normalizes at a certain level depending on conditions and on the carrier. The
temperature in the tank must not exceed the maximum allowed.
The hammer must not be started if the ambient temperature is below freezing and
the oil is very thick. The machine must be moved to bring the oil temperature above
0 °C (32 °F) before hammering can start (viscosity 1000 cSt or 131 °E).

Lubrication - Page 37
Carrier hydraulic oil
1322 STD
OIL SPECIFICATIONS
Table below shows hydraulic oils recommended for hammer use. The most suitable
oil is selected in such a way that the temperature of the hydraulic oil in continuous
use is in the ideal area on the chart and the hydraulic system is used to best
advantage.
Problems due to incorrect hydraulic oil viscosity in the hammer:
Oil too thick
■ Difficult start up
■ Stiff operation
■ Hammer strikes slowly
■ Danger of cavitation in pumps and in the hydraulic hammer
■ Sticky valves
■ Filter bypass opens, impurities in the oil are not removed
Page 38 - Lubrication
COPYRIGHT © 2016 SANDVIK MINING AND CONSTRUCTION OY
1322 STD
Carrier hydraulic oil
Oil too thin
■ Efficiency losses (internal leaks)
■ Damage to gaskets and seals, leaks
■ Accelerated wearing of parts, because of decreased lubrication efficiency
■ Hammer strikes irregularly and slowly
■ Danger of cavitation in pumps and in the hydraulic hammer
Note: We strongly recommend the use of different hydraulic oils in the summer and
in the winter if there is an average temperature difference of more than 35 °C (63
°F). The correct hydraulic oil viscosity is thus ensured.
SPECIAL OILS
In some cases special oils (for example biological oils and non-inflammable oils)
can be used with hydraulic hammers. Observe the following aspects when
considering the use of special oils:
■ The viscosity range in the special oil must be in the given range (20-1000 cSt)
■ The lubrication properties must be sufficient
■ The corrosion resistance properties must be good enough
Note: Although a special oil could be used in the carrier, always check its suitability
with the hammer due to high piston speed of the hammer. Contact the oil
manufacturer or your local dealer for more information about special oils.
2.2 OIL COOLER
The correct place to connect the hammer return line is between the oil cooler and
the main filters. The hammer return line should not be connected before the oil
cooler. Routing the hammer return flow through the cooler, might damage either the
cooler, due to pulsating flow, or the hammer, due to increased back pressure.
The carrier hydraulic system must be able to maintain the temperature within an
acceptable level during the hammer operation. This is for two reasons.
1. Seals, wipers, membranes and other parts manufactured from the corresponding
materials can normally stand temperatures up to 80 °C (176 °F).
2. The higher the temperature is, the less viscous the oil gets thus losing its
capability to lubricate.
COPYRIGHT © 2016 SANDVIK MINING AND CONSTRUCTION OY
Lubrication - Page 39
Carrier hydraulic oil
1322 STD
A standard carrier, with a proper hammer circuit, meets the requirements of the
necessary cooling capacity. If the oil temperature tends to be too high during the
hammer operation, the following things must be checked:
■ The hammer circuit pressure relief valve is not open when the hammer is
operated.
■ The hammer circuit pressure drops are reasonable. Less than 10 bar (145 psi) in
the pressure line and less than 5 bar (75 psi) in the return line.
■ Hydraulic pumps, valves, cylinders, motors etc. and hammer do not have
internal leakages.
If all of the above mentioned things are in order, and the temperature of the
hydraulic oil still tends to be too high, extra cooling capacity is needed. Consult the
carrier manufacturer or dealer for details.
2.3 OIL FILTER
The purpose of the oil filter is to remove impurities from the hydraulic oil. Air and
water are also impurities in oil. Not all impurities can be seen with the naked eye.
Impurities enter the hydraulic system:
■ During hydraulic oil changes and refilling.
■ When components are repaired or serviced.
■ When the hammer is being installed on the carrier.
■ Because of component wear.
Normally the existing main oil filters of the carrier are used as hammer circuit return
line filters. Consult the carrier manufacturer or your local dealer concerning
instructions for the filter change intervals.
In hydraulic hammer work the carrier oil filter must fulfil the following
specifications:
■ The oil filter must allow maximum particle size of 25 microns (0.025 mm).
■ The oil filter material must be artificial fibre cloth or very fine gauge metallic
mesh to withstand pressure fluctuations.
■ The oil filter must have a nominal flow capacity of at least twice the hammer's
maximum flow.
In general, oil companies guarantee new oils to have a particle count of 40 microns
maximum. Filter the oil when filling the tank.
The damage caused by hydraulic oil impurities in the carrier and hammer circuits:
1. The working life of the pumps and other components is significantly shortened.
■ Rapid wear of parts.
■ Cavitation.
2. Wear of cylinder and gaskets.
Page 40 - Lubrication

1322 STD
Carrier hydraulic oil
3. Reduced hammer efficiency.
■ Accelerated wear of moving parts and seals.
■ Danger of piston seizing up.
■ Oil leakages.
4. Shortened working life and reduced lubricating capability of oil.
■ Oil overheats.
■ Oil quality deteriorates.
■ Electro-chemical changes in hydraulic oil.
5. Valves do not function properly.
■ Spools bind.
■ Rapid wear of parts.
■ Blocking of small holes.
Note: Component damage is only a symptom. The trouble itself will not be cured
by removing the symptom. After any component damage due to impurities in the
oil, the entire hydraulic system has to be cleaned. Dismantle, clean and reassemble
the hammer and change the hydraulic oil.
