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

Slowly lift and transport the hydraulic breaker to its
intended destination.
Transport using a lorry
Put the hydraulic breaker on an anti-slip mat at the
lorry. Secure the machine to the loading surface
with straps.
Observe all the applicable national and regional
regulations on securing loads.
Installation
Before installing the hydraulic breaker on the
carrier or operating it, read the operation manual
and safety instructions provided by the carrier
manufacturer. Follow all instructions.
The carrier must have the appropriate hydraulic
system for operation of the breaker.
If the carrier is too large for the hydraulic breaker it
may lead to broken working tools and increased
wear. See "Technical data" for choosing suitable
carrier.
The safety equipment in the hydraulic system must
be checked for quality (CE mark, etc.), suitability
and functionability by a professional or authorised
supervisor before use.
Hoses and connections
WARNING Whipping hydraulic hose
Hydraulic hoses under pressure can whip
uncontrollably if screws loosen or are loosened. A
whipping hydraulic hose can cause severe injuries.
►Depressurize the hydraulic system before
loosening the connection of a hydraulic hose.
►Tighten the nuts on the connections of the
hydraulic hoses to the required torque.
Type of nipple: ORFS standard nipple. The nipple
dimensions can be found in the Spare parts list.
The quality of the hydraulic hoses should be 2SC
(according to EN 857) or better when connecting
the breaker to the carrier. If quick couplings are to
be used, we recommend using the 'Flat Face'
quick coupling. This type is sturdy and easy to
clean. The quick coupling pressure class must
agree with the carrier's working pressure.
Always clean the quick couplings before mounting
or dismounting. Always plug hoses and hose
nipples with tight and clean end caps when
dismounting.

are connected with an additional connection
nipple, another tightening torques must be used.
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 dirty faster. Check and follow
the carrier's instructions for changing oil and oil
filter. It is common to change the oil filter more
frequent when a hydraulic breaker is installed.
SB hydraulic breakers are equipped with an oil
drainage plug to drain all oil before dismounting.
This is to reduce the risk of spilling oil.

Insert toggle pin and lock.
9. After mounting the breaker, carefully extend
and retract the bucket cylinder to its full extent
in each direction. It is important that the
cylinder can be fully extended and retracted
without any difficulty.
10. Connect hydraulic hoses for 'Pressure line, to
breaker' and 'Tank, return line'. For further
information see section "Hoses and
connections".
Pressure adjustment
The hydraulic breaker is equipped with a pressure
relief valve which secures the breaker. The
operating pressure of the machine (max 150 bar)
is checked and adjusted by a pressure gauge
while operating the hydraulic breaker.
◆If the operating pressure is more than 150 bar
the pressure must be decreased. Reduce the
oil flow from the carrier until the pressure is
down to 150 bar. This adjustment is important
to ensure that the built in pressure relief valve in
the breaker does not open and leak oil back to
the tank and create heating problems.
◆If the operating pressure is between 130–150
bar, normally no adjustment is needed.
◆If the carrier's oil flow is too low to retain an
acceptable operating pressure the restrictor in
the breaker needs to be changed. See flow
diagrams in "Technical data" to choose the best
restrictor for your application.
Position the hydraulic breaker vertically towards
solid bedrock or similar to adjust the pressure
using a pressure gauge.
Water flushing
The hydraulic breaker is prepared for water
flushing, this function is to bind the dust when
performing demolition operations.
When connecting water flushing the plug in the
front of the breaker must be exchanged with a
water nozzle. See the Spare parts list for ordering
a new water nozzle.

1. Shut the carrier's engine off.
2. Dismount the working tool, use a lifting strap to
reduce the risk of personal injury.
3. Remove and check the lock buffer. Change
worn or damaged parts.
NOTICE The lock buffer in the tool retainer
lock is made of plastic and can melt when
operating in a hot environment. If this occurs,
change the standard lock pin. Find optional
spring pin in the spare parts list.
4. Clean and lubricate the bushing plentifully.
NOTICE When mounting a new working tool,
it is especially important to lubricate plentifully.

5. Mount the working tool, use a lifting strap to
reduce the risk of personal injury
6. Rotate the working tool to spread the grease.
7. Mount the tool retainers, one at the time.
8. Drive in the lock pin until the lock buffer
attaches in the lock pin groove.
Operation
NOTICE The hydraulic breaker or the working
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 -20ºC (-4ºF) and +80ºC
(+176ºF).
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 –20ºC
(-4ºF), you must warm up the working tool and
the hydraulic breaker before use.
►If the oil temperature exceeds +80ºC (+176ºF),
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.

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.
Never start the hydraulic breaker until both carrier
and the hydraulic breaker are in the correct
position.
◆Direct the hydraulic breaker in a position 90°
towards the object.
◆Start near the edge and work your way in
towards the middle. Never start in the middle of
large objects.
◆Never run the hydraulic breaker longer then 15
seconds on the same spot. Move the working
tool to a new position if the object does not
break.
◆Never bend with the working tool.
◆Use the correct feed pressure. When the feed
pressure is correct the hydraulic breaker is
working at its best and the vibrations are at a
minimum. Also the wear on the bushing and
inserted tool is kept to a minimum.
◆Listen to the sound from the hydraulic breaker.
The sound changes if there is any bending
between the working tool and bushing.
◆Never run the breaker with the boom cylinders
at their end positions. It may cause damage to
the carrier.

bar
1.5-2
NOTICE When operating under water the
hydraulic breaker must be fed with compressed air
to keep the area between the piston and the
inserted tool free from water. If the area between
the piston and the inserted tool gets filled with
water, it may penetrate into the hydraulic oil system
when the hydraulic breaker is started.
The air pressure must be 1.5-2 bar at the air inlet
on the breaker and the air consumption can be
found in "Technical data". Suitable air hose is a 1⁄4
in. hydraulic hose with JIC connection. Contact
your nearest authorised workshop for further
instructions.
Special applications
NOTICE Always consult the Customer Center /
Dealer in your area in case of special applications-
tunnelling, high thermal load and underwater
application.
You can contact your nearest authorised workshop
for further instructions.
Maintenance
It is essential that regular maintenance is
performed to maintain the breakers maximum
efficiency.
Equipment that is insufficiently maintained can be
dangerous for both the operator and persons near
the breaker. Make sure that regular maintenance
routines with lubrication are followed to keep the
equipment safe and efficient.
Cleaning
NOTICE Environmental damage due to polluted
water
Hydraulic oil and chisel paste are environmentally
harmful and must not penetrate the ground or
enter the water table or water supplies.
◆Collect the water used for cleaning if it has
been contaminated by hydraulic oil and chisel
paste.
◆Dispose of the water in accordance with the
applicable regulations to avoid environmental
hazards.
Every second hour
Regularly lubricate the working tool, the tool
retainer and the bushings.
Lubricating with a grease gun
WARNING Hot working tool during
operation and a period of time after use.
►Avoid contact with the working tool.
WARNING Hot hydraulic breaker during
operation and a period of time after use.

CAUTION Skin eczema
Grease can cause eczema if it comes in contact
with the skin.
►Avoid getting grease on your hands. Wash
thoroughly after contact.
1. Press the working tool all the way into the
breaker up to the stop (A). Otherwise the space
between the top of the working tool and the
piston will be filled with grease, and damage
can occur to seals, piston, and cylinder.

2. Lubricate the working tool's shank plentifully
during all upward operations. The bushing and
the working tool must be lubricated so
frequently that dirt cannot penetrate into the
hydraulic breaker.
When the working tool is exposed to high pressure
and high temperatures a standard type of grease
will melt and run. To avoid this always use Epiroc
chisel paste.

Central lubrication system
We recommend Epiroc's central lubrication
system. When this system is fitted on the carrier,
grease is pumped continuously from a lubrication
container on the carrier to the hydraulic breaker
when the hydraulic breaker is activated. This
increases the life of the tool bushings and working
tools considerably.
Every day
◆Check tool retainers and lock pins.
◆Check that hoses, couplings, and accumulator
are in a good condition.
◆Check that bolts and connections are free from
damage and properly tightened. See tightening
torques in the spare parts list.
◆Refill the central lubricating system.
Every week
◆Clean the hydraulic breaker carefully.
◆Check the wear bushing's wear and maximum
inner wear limits.
A
The wear bushing must be replaced when the
inner diameter (A) has reached its maximum
wear limit, see section "Wear limits" and
"Replacing the working tool bushing".
◆Check the working tool for wear.
The working tool must be replaced when the
outer diameter (B) has reached its minimum
wear limit. See section "Wear limits".
B
Too large clearance can make the working tool
break and the piston can be damaged.
◆Check the breaker and the adapter plate for
cracks and wear.
◆Check that the accumulator screws are properly
tightened. The correct tightening torque is found
in the spare parts list.
The working tool may never be sharpened by
forging. Sharpening must only be performed by
milling, grinding, or turning.

Replacing the working tool bushing
The working tool bushing is kept in place by the
tool retainers. A new bushing has a slip fit.
1. Remove scraper ring and bushing. If a worn out
bushing is stuck, use a sliding hammer to
remove it.
2. Carefully clean the bore and the bushing seat
area.
3. Mount new O-rings, lubricate and mount the
bushing.
4. Use a plastic sledgehammer to insert the
bushing.
