Hydraulic oil

Normally the type of hydraulic oil the carrier isusing also works for the hydraulic breaker. When ahydraulic breaker is connected to the carrier, thehydraulic oil will get dirty faster. Check and followthe carrier's instructions for changing oil and oilfilter. It is common to change the oil filter morefrequent when a hydraulic breaker is installed.SB hydraulic breakers are equipped with an oildrainage plug to drain all oil before dismounting.This is to reduce the risk of spilling oil.

NOTICE When the SB breaker is delivered itcontains some mineral based hydraulic oil. Beforeconnecting to the carrier's hydraulic system, checkwhich type of hydraulic oil the carrier is using.Mixing different types of hydraulic oil may destroythe lubrication quality which can lead to machinedamage.

In order to protect the environment we recommendthe use of biologically degradable hydraulic oil.

Viscosity Viscosity (permitted) 15-100 cSt

NOTICE Always use clean oil and fillingequipment.

Assembly

Circulate the hydraulic oil before connecting thehydraulic breaker. This is to make sure that thehydraulic oil is clean. Use the same routine whenchanging the hydraulic oil hose. For furtherinformation see section "Hydraulic oil".1. Connect the pressure and return hoses.

2. Run the hydraulic oil through the carrier's oilfilter for approximately 3 minutes to make surethat the hoses are clean.

WARNING Falling breaker can causeinjuries► Place the breaker in a safe position where it

can not fall over and cause damage.

Preparation1. Place the breaker in a position where it is easy

and safe to mount the adapter plate.

NOTICE Mount the breaker so that theaccumulator faces the operator's cabin, toreduce the risk of accumulator damage.

Pressure adjustment

The hydraulic breaker is equipped with a pressurerelief valve which secures the breaker. Theoperating pressure of the machine (max 150 bar)is checked and adjusted by a pressure gaugewhile operating the hydraulic breaker.◆ If the operating pressure is more than 150 bar

the pressure must be decreased. Reduce theoil flow from the carrier until the pressure isdown to 150 bar. This adjustment is importantto ensure that the built in pressure relief valve inthe breaker does not open and leak oil back tothe tank and create heating problems.

◆ If the operating pressure is between 130–150bar, normally no adjustment is needed.

◆ If the carrier's oil flow is too low to retain anacceptable operating pressure the restrictor inthe breaker needs to be changed. See flowdiagrams in "Technical data" to choose the bestrestrictor for your application.

Position the hydraulic breaker vertically towardssolid bedrock or similar to adjust the pressureusing a pressure gauge.

Water flushing

The hydraulic breaker is prepared for waterflushing, this function is to bind the dust whenperforming demolition operations.When connecting water flushing the plug in thefront of the breaker must be exchanged with awater nozzle. See the Spare parts list for orderinga new water nozzle.

Use a ¼ in. hydraulic hose with a JIC connectionas a proper water hose. Contact your nearestauthorised workshop for further instructions.

NOTICE It is recommended to use water flushingto reduce the wear on the hydraulic breaker duringtunnel and dust-intensive applications.

OperationNOTICE The hydraulic breaker or the workingtool is not to be used as a lifting device. Whenlifting heavy components use the hook on thecarrier arm.

Preparation before breaking

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

CAUTION Temperature hazardThe hydraulic breaker and the hydraulic oil systemof the carrier can be damaged if the hydraulicbreaker is 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 andthe hydraulic breaker before use.

► If the oil temperature exceeds +80ºC (+176ºF),you must not use the hydraulic breaker as theoil quality 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 surethat no persons are in the risk area, 20 metersboth horizontally and vertically from the hydraulicbreaker.

Breaking

CAUTION Machine and tool hazardContinuous 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 fully

extended 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 correctposition.◆ Direct the hydraulic breaker in a position 90°

towards the object.

◆ Start near the edge and work your way intowards the middle. Never start in the middle oflarge objects.

◆ Never run the hydraulic breaker longer then 15seconds on the same spot. Move the workingtool to a new position if the object does notbreak.

◆ Never bend with the working tool.

◆ Use the correct feed pressure. When the feedpressure is correct the hydraulic breaker isworking at its best and the vibrations are at aminimum. Also the wear on the bushing andinserted tool is kept 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 cylindersat their end positions. It may cause damage tothe carrier.

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

◆ The hydraulic breaker or the working tool is notto be used as a lifting device. When liftingheavy components use the hook on the carrierarm.

◆ Never use the hydraulic breaker as a sledgehammer to demolish material.

Cleaning

NOTICE Environmental damage due to pollutedwater

Hydraulic oil and chisel paste are environmentallyharmful and must not penetrate the ground orenter the water table or water supplies.◆ Collect the water used for cleaning if it has

been contaminated by hydraulic oil and chiselpaste.

◆ Dispose of the water in accordance with theapplicable regulations to avoid environmentalhazards.

Every second hour

Regularly lubricate the working tool, the toolretainer and the bushings.

Lubricating with a grease gun

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

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

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

thoroughly after contact.

1. Press the working tool all the way into thebreaker up to the stop (A). Otherwise the spacebetween the top of the working tool and thepiston will be filled with grease, and damagecan occur to seals, piston, and cylinder.

A

2. Lubricate the working tool's shank plentifullyduring all upward operations. The bushing andthe working tool must be lubricated sofrequently that dirt cannot penetrate into thehydraulic breaker.

When the working tool is exposed to high pressureand high temperatures a standard type of greasewill melt and run. To avoid this always use Epirocchisel paste.

Central lubrication systemWe recommend Epiroc's central lubricationsystem. When this system is fitted on the carrier,grease is pumped continuously from a lubricationcontainer on the carrier to the hydraulic breakerwhen the hydraulic breaker is activated. Thisincreases the life of the tool bushings and workingtools considerably.

Every day

◆ Check tool retainers and lock pins for damage,change if necessary.

◆ Check that hoses, couplings, and accumulatorare in a good condition, change if necessary.

◆ Check that bolts and connections are free fromdamage and properly tightened, change ifdamaged. See tightening torques in the spareparts list.

◆ Refill the central lubricating system.◆ Check that wear plate and bolts are free from

damage, change if necessary.
