OPERATIONBREAKINGThe operator should note the sound of the blow whenthe breaker is running. With experience, the operator willbe able to tell the difference between a good solid blowand a hollow sounding blow. A hollow blow means thatsolid blows are not occurring and the breaker should berepositioned.Continuous tool penetration usually does not do muchgood. If the material does not break with 3 to 4 inches oftool penetration, it usually won’t break with full penetration. The time used for addi

OPERATIONExcessive side force cocks the tool in its bore, pre-ventsproper movement and causes premature tool shankand bushing wear. Since the breaker tool bit must bepushed up into the breaker to operate, a binding toolprevents the breaker from operating correctly. Bindingalso causes the tool bit and tool bushings to seize andoften results in breakage of one or more breaker components. Always direct the down pressure force in a linetoward the point of tool contact with the work.NOTICEDO NOT pry

PROPER USE & CARE OF TOOL BITSTool bits are made and heat treated to specification.Tool bits, however well made, are wear parts, and areused in the most destructive applications. Even whenthe hydraulic breaker is used properly, and the operatoris an experienced one, a tool bit may become damaged.When a tool bit has been damaged, it is useful to determine the cause immediately in order to prevent thedamage from occurring again.All Stanley tool bits are machined and hardened formaximum performance

PROPER USE & CARE OF TOOL BITSIn its most extreme forms, the combination of surfacedamage and severe bending can quickly break even thebest working steels.The illustrations below show examples of severe stressbreaks.Figure 15. Severe Stress BreaksPRYINGThis is the most common cause of tool failure. Evenwhen there is no surface damage, the stress from prying can easily break a working steel. This kind of failuregenerally results from any type of side pressure such asan incorrect breaking angle or

PROPER USE & CARE OF TOOL BITSTOOL FAILURE COVERED UNDERWARRANTYINTERNAL MATERIAL FLAWThis failure occurs when a foreign material is rolled intothe steel during the manufacturing process, causing animperfection in the internal material flaw grain. The result is an inherent weakness in the tool shank and eventual breakage.The fatigue failure is started by the defects within the toolbit. The broken surface exhibits a shell pattern aroundthe starting point of failure, like that in the fatigue failu

PROPER USE & CARE OF TOOL BITSStanley Breakers are available with several different types of tool bits. The most common are the moil, chisel andthe blunt. Each of these working steels has its own purpose as described below:To obtain the maximum production from the breaker, it is important to select the proper working steel. Consult yourStanley representative for assistance in selecting the proper working steel for your application.MOILThis is by far the most popularworking steel. It is a general
