4. Mount the retainer pin, and make sure it remainsin position so it not falls through the boring atthe back.

5. Drive in the spring pin by using a break pinpunch and a hammer, until it is flushed with thepercussion unit.



OperationNOTICE The hydraulic breaker or the working toolis not to be used as a lifting device. When liftingheavy components use the hook on the carrier arm.

Preparation before breaking

Operating temperaturesThe operating temperatures of the hydraulic breakerare between -20ºC (-4ºF) and + 80ºC (+176ºF).

CAUTION Temperature hazardThe hydraulic breaker and the hydraulic oil systemof the carrier can be damaged if the hydraulic breakeris used at higher or lower temperatures.►Only start the hydraulic breaker when the

hydraulic oil has reached the proper operatingtemperature.

► If the ambient temperature is below – 20ºC (-4ºF),you must warm up the working tool and thehydraulic breaker before use.

► If the oil temperature exceeds + 80ºC (+176ºF),you must not use the hydraulic breaker as the oilquality becomes inadequate which severelyshortens the life time of seals and O-rings.

Engine rpmToo high engine rpm only results in increased fuelconsumption and increased oil temperature. Adaptthe engine rpm to the recommended value to givethe correct operating oil flow.

Operating

Risk areaBefore starting the hydraulic breaker, make sure thatno persons are in the risk area, 20 meters bothhorizontally and vertically from the hydraulicbreaker.

20 m

BreakingCAUTION Machine and tool hazard

Continuous operation at full extension and/orretraction can result in damage to the hydrauliccylinders.►Always avoid operating the breaker with the

cylinders fully extended or retracted.

►Reposition the carrier and/or boom to avoid fullyextended or retracted cylinders.

►Pay attention and look at what you are doing.

Never start the hydraulic breaker until both carrierand 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 towardsthe middle. Never start in the middle of largeobjects.

♦ Never run the hydraulic breaker longer then 15seconds on the same spot. Move the working toolto a new position if the object does not break.

♦ Never bend with the working tool.

♦ Use the correct feed pressure. When the feedpressure is correct the hydraulic breaker is workingat its best and the vibrations are at a minimum.Also the wear on the bushing and inserted tool iskept to a minimum.

♦ Listen to the sound from the hydraulic breaker.The sound changes if there is any bendingbetween the working tool and bushing.

♦ Never run the breaker with the boom cylinders attheir end positions. It may cause damage to thecarrier.



♦ Avoid idling strokes; it causes wear on bothworking tool and tool retainers.

Use under water♦ Never use the hydraulic breaker under water.

This would seriously damage the hydraulic breakerand may damage the whole hydraulic installation.

MaintenanceIt is essential that regular maintenance is performedto maintain the breakers maximum efficiency.Equipment that is insufficiently maintained can bedangerous for both the operator and persons nearthe breaker. Make sure that regular maintenanceroutines with lubrication are followed to keep theequipment safe and efficient.

Lubrication

Lubricate the chisel shank thoroughly every twohours using high-temperature grease such asgenuine chisel grease from your supplier. This alsolubricates the bushing and the tool holder; 5-10pumps of the grease gun is sufficient. Stop whenthe grease starts to emerge at the chisel holder orbetween the chisel and the bushing.

WARNING Running engineIf the carrier's engine is running when lubricatingthe chisel by hand there is a risk of severe accidents.►Always switch off the carrier's engine to avoid

accidents.

During lubrication, the chisel must be pressedagainst the hammer piston so that the spacebetween piston and the chisel does not fill withgrease.

WARNING Explosion hazardUse of other gases than Nitrogen (N2) can cause anexplosion.►Charge the accumulator with Nitrogen (N2) only!

CP supplies a service box containing all necessarytools and parts required to service the pistonaccumulator. See the Spare parts list.If the hammer's performance begins to deteriorate,we recommend that you check the pressure in thepiston accumulator.NOTICE The pressure must be checked with thehammer at a working temperature of 60º-70ºC.To measure the pressure, bring down the hammerwith no pressure on the chisel. Detach the plug fromthe charge valve (G) and connect the test pressuregauge.The piston accumulator only needs to be filled if thepressure falls below the minimum level.

Filling1. Connect pressure relief valve (B) to gas bottle

valve (A).

2. Connect gas hose (C) to pressure relief valve (B)as shown in figure.

3. Close pressure relief valve (B).

4. Open gas bottle valve (A).

5. Remove the plug from the charge valve (G).

6. Guide the nozzle of the hose (C) into the chargevalve.

7. Carefully open the relief valve (B).

8. Fill the piston accumulator.

9. Read the pressure on the pressure gauge (D).

10. Close the pressure relief valve when the desiredpressure has been reached.Pull the gas hose out of the charge valve (G) andfit the plug.

Checking and reducing the gas pressure1. Always use the gas hose (C) and the pressure

gauge (D) when checking the gas pressure.

2. Connect the gas hose to the pressure gauge.

3. Remove the plug from the charge valve (G).

4. Press the nozzle of the gas hose into the chargevalve and read the pressure.

5. Reduce the pressure by repeatedly inserting andremoving the nozzle.

NOTICE Only the nozzle may be used to reducethe pressure. Never use pins, screwdrivers etc. asthese can damage the charge valve.

Every second hour

Regularly lubricate the working tool, the tool retainerand the bushings.

Lubricating with a grease gunWARNING Hot working tool during

operation and a period of time after use.►Avoid contact with the working tool.

WARNING Hot hydralic breaker duringoperation and a period of time after use.►Avoid contact with the hydralic breaker.

CAUTION Skin eczemaGrease can cause eczema when it comes in contactwith the skin.►Avoid getting grease on your hands. Wash

thoroughly after contact.

1. Press the working tool against the piston so thatthe space between the piston and the workingtool does not fill with grease.

2. Lubricate the working tool's shank plentifullywhile pressing the working tool against thesurface to avoid filling the cavity with grease. Ifthe cavity is filled with grease when the hydraulicbreaker is started, the lower seals may bedamaged.

When the working tool shank is exposed to highpressure and high temperatures a standard type ofgrease will melt and run. To avoid this always use agenuine working tool grease from your supplier.

Central lubrication systemWe recommend Chicago Pneumatic's centrallubrication system. When this system is fitted on thecarrier, grease is pumped continuosly from alubrication container on the carrier to the breakerwhen the breaker is activated. This increases the lifeof the tool bushings and insertion tools considerably.

Every day

♦ Check the tool retainer and split pin.

♦ Check that hoses, couplings and accumulator arein a good condition.

♦ Check that bolts and connections are free fromdamage and properly tightened. See tighteningtorques in the spare parts list.

♦ Refill the central lubricating system.



Every week

♦ Clean the hydraulic breaker carefully.

♦ Check the wear bushing's wear and maximuminner wear limits.

A

The wear bushing must be replaced when theinner diameter (A) has reached its maximum wearlimit, see section "Wear limits" and "Replacingthe working tool bushing".

♦ Check the working tool for wear.The working tool must be replaced when theouter diameter (B) has reached its minimum wearlimit. See section "Wear limits".

B

Too large clearance can make the working toolbreak and the piston can be damaged.

♦ Check the breaker and the adapter plate for cracksand wear.

♦ Check that the accumulator screws are properlytightened. The correct tightening torque is foundin the spare parts list.

The working tool may never be sharpened byforging. Sharpening must only be performed bymilling, grinding, or turning.

Replacing the working tool bushingThe working tool bushing is kept in place by the toolretainer. A new bushing has a slip fit.

1. If a worn out bushing is stuck, use a slidinghammer to remove it.

2. Carefully clean the bore and the bushing seatarea.

3. Lubricate and mount the bushing.

4. Use a plastic sledgehammer to insert thebushing.

5. Keep the bushing in position with help of thetool retainer.

Every year

Overhauling must be done after one year ofcontinuous operation. Overhauling must for safetyreasons be performed by authorised personnel atan authorised workshop.

StorageWARNING Falling breaker can cause

injuries►Place the hydraulic breaker in a safe position

where it can not fall over and cause damage.

If the hydraulic breaker is not used for a long time,the following points have to be considered to protectthe hydraulic breaker from corrosion:



1. Clean the hydraulic breaker carefully.

2. Dismount the working tool and lubricate thefront part of the piston, wear bushing, and theretainer pin.

3. Store the hydraulic breaker in a dry place.

Always keep the breaker in an upright position, ifstored for a long time.

DisposalA used machine must be treated and scrapped insuch a way that the greatest possible portion of thematerial can be recycled and any negative influenceon the environment is kept as low as possible.Before a used machine is scrapped it must beemptied and cleaned from all hydraulic oil. Theremaining hydraulic oil must be deposited and anynegative influence on the environment is to be keptas low as possible.
