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 insertion tools and increased
wear. See "Technical data" for choosing suitable
carrier.
The safety equipment in the hydraulic system must
becheckedforquality(CE mark,etc.),suitabilityand
function ability by a professional or authorized
supervisor beforeuse.
Hoses and connections
Read through the overhaul instructions carefully
before servicing or charging.
The accumulator must only be charged with
Nitrogen.
NOTICE Only certified personnel are allowed to
work with the accumulator.
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: Quick Attach JIC 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, were commend using the "Flat Face"
quick coupling. This type is sturdy and easy to
clean. The quick couplings pressure class must
agree with the carrier's working pressure.

Safety and operating instructions
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.
◆ Never bend with the insertiontool.
◆ Use the correct feed pressure. When the feed
pressureis correctthehydraulicbreakeris 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 inserted tool and bushing.
◆ Never run the breaker with the boom cylinders at
their end positions. It may cause damage to the
carrier.
◆ 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 than 15
seconds on the same spot. Move the inserted
tool to a new position if the object does not
break.

Safety and operating instructions
◆ Avoid idling strokes; it causes wear on both
inserted tool and tool retainers.
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.
Lubrication
Lubricate the chisel shank thoroughly every two
hours using high-temperature grease such as
genuine chisel grease from your supplier. This also
lubricates the bushing and the tool holder; 5-10
pumps of the grease gun is sufficient. Stop when
the grease starts to emerge at the chisel holder or
between the chisel and the bushing.
WARNING Running engine
If the carrier's engine is running when lubricating
thechiselbyhand,there is a risk ofsevere
accidents.
►Always switch off the carrier's engine to avoid
accidents.
During lubrication, the chisel must be pressed
against the hammer piston so that the space
between piston and the chisel does not fill with
grease.
WARNING Explosion hazard
Use of other gases than Nitrogen (N2) can cause an
explosion.
►Charge the accumulator with Nitrogen (N2) only!
QA supplies a service box containing all necessary
tools and parts required to service the piston
accumulator. See the Spare parts list.
If the hammer's performance begins to deteriorate,
we recommend that you check the pressure in the
piston accumulator.
NOTICE The pressure must be checked withthe
hammer at a working temperature of60º-70ºC.
To measure the pressure, bring down the hammer
with no pressure on the chisel. Detach the plug from
the charge valve (G) and connect the test pressure
gauge.
The piston accumulator only needs to be filled if the
pressure falls below the minimum level.

Checking and reducing the gas pressure
1. Always use the gas hose (C) and the pressure
gauge (D) when checking the gas pressure.
2. Connect the gas hose to the pressuregauge.
3. Remove the plug from the charge valve(G).
4. Press the nozzle of the gas hose into the charge
valve and read thepressure.
5. Reducethepressurebyrepeatedlyinsertingand
removing thenozzle.
NOTICE Only the nozzle may be used to reduce
the pressure. Never use pins, screwdrivers etc. as
these can damage the charge valve.
Every second hour
Regularly lubricate the insertion tool, the tool
retainer and the bushings.
Lubricating with a grease gun
WARNING Hot insertion tool during
operation and a period of time after use.
►Avoid contact with the insertion tool.
WARNING Hot hydraulic breaker
during operation and a period of time after
use.
►Avoid contact with the hydraulic breaker.
CAUTION Skin eczema
Grease can cause eczema when itcomes in contact
with theskin.
►Avoid getting grease on your hands. Wash
thoroughly after contact.
1. Press the insertion tool against the piston so
that the space between the piston and the
insertion tool does not fill withgrease.
2. Lubricate the insertion tool's shank plentifully
while pressing the insertion tool against the
surface to avoid filling the cavity with grease. If
thecavityis filledwithgreasewhenthehydraulic
breaker is started, the lower seals may be
damaged.
When the insertion tool shank is exposed to high
pressure and high temperatures a standard type of
grease will melt and run. To avoid this always use a
genuine insertion tool grease from your supplier.
Central lubrication system
We recommend centrallubrication carrier,
grease is pumped continuously from a lubrication
container on the carrier to the breaker when the
breaker isactivated.Thisincreases thelife of the tool
bushingsandinsertiontoolsconsiderably.
Every day
◆ Check the tool retainer and split pin.
◆ 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.

Safety and operating instructions
Every week
◆ Clean the hydraulic breaker carefully.
◆ Check the wear bushings wear and
maximum inner wear limits.

The wear bushing must be replaced when the
innerdiameter(A)hasreached itsmaximum wear
limit, see section "Wear limits" and "Replacing
the insertion tool bushing".
◆ Check the working tool forwear.
The working tool must be replaced when the
outer diameter (B)has reached its minimum wear
limit. See section "Wear limits".
Too large clearance can make the working tool
break and the piston can be damaged.
◆ Checkthebreakerandtheadapterplateforcracks

Replacing the insertion tool bushing
The insertion tool bushing is kept in place by the
tool retainer. A new bushing has a slip fit.
1. If a worn-out bushing is stuck, use a sliding
hammer to removeit.
2. Carefully clean the bore and the bushing seat
area.
3. Lubricate and mount thebushing.
4. Use a plastic sledgehammer to insertthe
bushing.
5. Keep the bushing in position with help of the
toolretainer.
Every year
Overhauling must be done after one year of
continuous operation. Overhauling must for safety
reasons be performed by authorized personnel at
an authorized workshop.
