PRE-INSTALLATIONINSTRUCTIONS
BACKHOE OR EXCAVATOR SIZE
Check the "specifications" section of this manual todetermine correct backhoe and excavator sizesand hydraulic flow and pressure requirements.
EXISTING EQUIPMENT HYDRAULICS VSAPPLICATION ATTACHING KITS
Using existing equipment hydraulic systems foroperating hydraulic tools could cause problems forthe hydraulic tool and the hydraulic system if notset up properly. Simply plugging into the hydraulicsystem without confirming pressure and flow to thehydraulic tool is not a good practice. Spare spoolvalves, backhoe extendable dipper circuits, etc.,are just a few examples of easily accessablehydraulic circuits which could prove to causeproblems for hydraulic tool usage.
Stanley Hydraulic Tools has for many yearsdeveloped ATTACHING KITS for adapting toexisting hydraulic systems of many popularbackhoes and excavators.
If your equipment does not contain an attachingkit, ask your Stanley dealer for information, instal-lation, and pricing on a kit which matches yourequipment needs.
TEST THE HYDRAULIC SYSTEM
1. Have your Stanley dealer test the backhoe/excavator hydraulic system to make sure thesystem is operating at the manufacturers specifiedcapacity and pressure ratings.
2. Be sure the fluid in the hydraulic system isfiltered to a least 10 micro-meters. (Particlesfound in fluid should not exceed 10 micro-metersin size.)
IF HYDRAULIC PRESSURE, HYDRAU-LIC BACK-PRESSURE, OR HYDRAULICFLOW ARE EXCEEDED, THE TOOLWARRANTY IS VOID.

LOW-TEMPERATURE WARM-UP PROCEDURE
1. After starting the backhoe/excavator, warm-upthe hydraulic system at engine idle until hydrauliclines are warm to the touch.
2. With the backhoe or excavator at idle and thebreaker suspended in the air, turn on the breaker togradually warm up its internal components.
3. When the hydraulic system and breaker arewarm, proceed with operation. SEE THE "OP-ERATION" SECTION OF THIS MANUAL.
LONG TERM STORAGE
1. Remove the tool bit, clean the tool stop and thelower bushing. Thoroughly coat the surfaces of thetool stop and the lower bushing with grease.
2. If hoses are attached to the breaker, installplugs on the hose ends. If hoses are removedfrom the breaker, install plugs on the hose endsand install plugs in the breaker "IN" and "OUT"ports.
3. Store the breaker in a vertical position. Do notstore the breaker on its side for extended periods.

• GENERAL INSTRUCTIONS
The Stanley MB256 and 356 breakers areequipped with an internal hammer cushion whichprotects the breaker against a blank blow whenthere is nothing under the point to absorb theenergy. Maintaining hard contact with the surfaceof the material to be broken in addition to maintain-ing adequate "down force" is very important.Always keep "down pressure" or "down force" onthe point of the breaker by lifting the wheels,tracks, or stabilizers slightly above the ground.This method takes the "slack" out of the bracketand boom pivots, and reduces the impact on thepivots in the boom.
The operator should note the sound of the blowwhen the breaker is running. With experience, theoperator will be able to tell the difference betweena good solid blow and a hollow sounding blow. Ahollow blow means that a partial blank blow isoccuring and the breaker should be repositioned.
In any breaking job, the operator should makeevery effort to “follow” the breaker with “down-pressure” as the machine breaks farther into thematerial. The breaker should be deactivated assoon as “break-thru” occurs or if it is apparent thata partial blank blow is occuring.
• POSITIONING THE BREAKERTOOL ON THE WORK MATERIAL
The tool should be placed near the edge of workmaterial, not in the center or far from the edge.
Position the tool 6-18 inches (depending on thematerial) from the edge. Breaking off smallerpieces of rock or concrete usually accomplishesmore than trying to break larger pieces.
On flat material or rock, the breaker should bevertical or “curled” back slightly to direct the impactforce downward and toward the backhoe. Thisdirects the force back toward the edge of the workmaterial. If the tool is positioned in the center ofthe work, or too far from the edge, the energy willbe absorbed into the material without cracking it.Do not run the breaker longer than 15-20 seconds.If breakout does not occur within this time, move toanother location.
• POSITIONING THE CARRIER
Backhoes
With the breaker tool in place on the material to beworked, position the backhoe so the boom ishalfway up (45°) and the dipper holds the breakeralmost vertical. Lower the loader bucket until theweight is off the front tires.
Apply down force to the boom/dipper until the rearof the backhoe is raised off the ground. Rear tiresand stabilizers should be off the ground so the totalrear weight of the backhoe is on the breaker tool.Keep raising the backhoe as the tool penetratesthe work material so the backhoe weight stays onthe tool. The breaker is more efficient whenadequate down force is applied.
Excavators
With the breaker tool in place on the material to beworked, position the excavator so the dipper is atapproximately 45° and the breaker is almost

vertical. The tracks of the excavator should be inline with the booms and the breaker.
• RELOCATE THE BREAKEROFTEN
Many materials do not respond well to continuedhammering in one place. The breaker tool shouldbe moved to a new location of the work each timethe tool penetrates but does not crack the material.
This calls for the “scoring” method of breaking.This technique involves striking the rock or con-crete at several places along a Iine where youwant the crack to occur. Most materials breaksooner when struck several places along a linethan when struck repeatedly in one location. Ateach place, the breaker tool should be continuallyrepositioned. Practice determines the best lengthof time to stay in one spot (15-20 seconds) andhow far to move the breaker tool.
• MISCELLANEOUS TIPS
Continuous Tool Penetration usually does notdo much good. If the material does not break with3 to 6 inches of tool penetration, it usually won’tbreak with full penetration. The time used foradditional penetration could be better used to strikeblows in another place.
Breaker Tool Binding can cause erratic breakeroperation and premature wear on the tool shank.Breaker tool binding is caused by failure to directthe backhoe down force in the direction of the tool.Excessive side force cocks the tool in its bore, pre-vents proper movement and causes premature toolshank and bushing wear. Since the breaker toolmust be pushed into the breaker to operate, abinding tool prevents the breaker from operatingcorrectly. Always direct the backhoe force towardthe point of tool contact with the work. Seeillustration on next page.
IMPORTANTContinuous penetration in the samearea for lengthy periods will createexcessive temperatures at the tip ofthe tool bit resulting in loss of temper(hardness) of the bit, mushrooming ofthe tip of the bit, and may lead tofailure of the bit.

Apply down force
Do not break continouslyin one place
Scoring with thebreaker
Rebar Reinforced Concrete introduces theproblem of concrete chunks being held together bythe rebar after the concrete has been broken. Thebest approach to this problem is to use a chiselpoint tool which permits cutting the rebar with thebreaker. Another method is to periodically cut therebar with a torch.
Grease should be applied to the upper end of thebreaker tool bit each time it is installed. Thereafter,the tool should be greased at the fitting to reducewear in the lower body and bushings of the tool.SEE "GREASING THE TOOL BIT" IN THE SEC-TION TITLED "PREPARATION FOR USE".
Underwater usage of the MB256 or 356 willcause damage to the breaker. Even if the breakeris partially submerged, water is introduced to anarea between the tool bit and piston. On the pistondown cycle, the water becomes compressed anddamages adjacent components.
10
DO NOT PRY WITH THE BITAND BREAKER!
IMPORTANTIMPORTANTUNDERWATER USE
No part of the Stanley MB256 or MB356Breaker may be submerged in waterwithout first modifying the breaker forunderwater use. Use of the breakerunderwater requires an underwaterapplication kit and an air compressorcapable of producing 150 CFM @ 75 PSI.Underwater usage of the breaker withoutthe underwater kit and air compressorwill cause internal damage to the breaker.See the "ACCESSORIES" section of thismanual to order the underwater kit.

DAILY MAINTENANCECHECKS
• Check for loose or missing fasteners. Tighten orreplace as needed.
• Inspect tool retaining pins and pockets for wear.
• Check for hydraulic leaks at all fittings andhoses. Replace any defective hoses.
• Apply grease through the grease fitting in thelower body each morning. Grease as neededthroughout the work day.
• Inspect the lower bushing, tool retainer, roll pins.Reseat or replace if necessary.
PRINCIPLE OF OPERATIONGENERAL
The breaker piston contains two areas which are larger in diameter than other areas of the piston. Inbetween these two larger diameter areas is an area which is smaller in diameter. The top and bottom ofthe piston, which are located on each side of the two larger diameter areas, are also smaller in diameter.
As the piston moves up and down in the piston sleeve, the larger diameter areas of the piston block theflow of incoming hydraulic fluid trying to pass through the piston sleeve and into the chambers shown inthe illustrations on the next page. The smaller diameter areas allow the hydraulic fluid to pass throughto the chambers.
The piston cannot operate totally by itself. It needs assistance in directing hydraulic fluid to some of itssurfaces in order for it to move. This is accomplished by a valve and valve spool. The combinedmovement of the valve spool and piston result in the up and down cycles of the breaker as describedbelow.
BLANKFIREUP CYCLE (see UP CYCLE illustration)
When the piston reaches the bottom of its stroke, CHAMBER "C" becomes open to the oil "RETURN"port. Note that CHAMBER "A" is also open to the "RETURN" port and CHAMBER "D" is open to the"PRESSURE" port. With CHAMBER "C" and "A" open and "D" closed to "RETURN", the ends of thevalve spool are exposed to different pressures and the valve spool shuttles to the position shown in the"UP CYCLE" illustration.
Hydraulic fluild flowing into CHAMBER "D" builds pressure and the piston is forced upward.
As the piston rises into the accumulator chamber, the nitrogen gas charge in the accumulator is com-pressed.
DOWN CYCLE (see DOWN CYCLE illustration)
CHAMBER "C" is now exposed to high pressure and the valve spool is shuttled and held in the positionshown in the "DOWN CYCLE" illustration. Hydraulic fluild flowing into CHAMBER "A" builds pressureand the piston is now forced downward. The compressed nitrogen in the accumulator gives the pistonan added push.
The piston strikes the tool bit, CHAMBER "C" becomes open to the oil "RETURN" port, and the "UPCYCLE" begins.
