Make sure the circuit PRESSURE hose with male quick disconnect is connected to the IN port The circuit RETURN hose with female quick disconnect is connected to the opposite port Do not reverse cir cuit flow This can cause damage to internal seals Always replace hoses couplings and other parts with replacement parts recommended by Stanley Hydraulic Tools Supply hoses must have a mini mum working pressure rating of 2500 psi 172 bar Do not exceed the rated flow and pressure See Specifications in this manual for correct flow rate and pressure rating Rapid failure of the internal seals may result Always keep critical tool markings such as warning stickers and tags legible Do nat force a small breaker to do the job of a large breaker Keep tool bit sharp for maximum breaker perfor mance Make sure that tool bits are not chipped or rounded on the striking end Never operate a breaker without a tool bit or without holding it against the work surface This puts exces sive strain on the breaker foot Tool repair should be performed by experienced personnel only Make certain that the recommended relief valves are installed in the pressure side of the system Do not use the tool for applications for which it was not intended 12 gt BR37 User Manual TROUBLESHOOTING PROBLEM CAUSE REMEDY Tool does not run Power unit not functioning Check power unit for proper flow and pressure 7 9 gpm 26 34 Ipm 15002. 2000 psi 105 140 bar Pressure and return line hoses Be sure hoses are connected to their proper reversed at ports ports Mechanical failure of piston or Disassemble breaker and inspect for automatic valve damaged parts Tool does not hit effectively Power unit not functioning Check power unit for proper flow and pressure 7 9 gpm 26 34 lpm 1500 2000 psi 105 140 bar Low accumulator charge Recharge accumulator Replace diaphragm if pressure hose will pulse more charge loss continues than normal Fluid too hot above Provide cooler to maintain proper fluid 140 F 60 C temperature 140 F 60 C Tool operates slow Low gpm supply from power Check power unit for proper flow 7 9 unit gpm 26 34 Ipm High backpressure Check hydraulic system for excessive backpressure over 200 psi 14 bar Orifice plug blocked Fluid too hot above Check power unit for proper fluid temperature 140 F 60 C or too cold Bypass cooler to warm the fluid or provide below 60 F 16 C cooler to maintain proper temperature Relief valve set too low Adjust relief valve to 2100 2250 psi 145 155 bar Tool gets hot Hot fluid going through tool Check power unit Be sure flow rate is not too high causing part of the fluid to go through the relief valve Provide cooler to maintain proper fluid temperature 140 F 60 C max Check the relief valve setting Eliminate flow control devices Fluid leakage on tool bit L

4. It is a good practice to connect return hoses first and discon nect them last to minimize or avoid trapped pressure within the tool 3 Observe flow indicators stamped on hose couplers to ensure that fluid flow is in the proper direction The female coupler on the tool hose is the inlet cou pler 4 Move the hydraulic circuit control valve to the ON position to operate the tool NOTE If uncoupled hoses are left in the sun pressure in crease within the hoses may make them difficult to connect When possible connect the free ends of the hoses together OPERATION PROCEDURES 1 Observe all safety precautions 2 Install the appropriate tool bit for the job 3 Place the bit firmly on the surface to be broken 4 Squeeze the trigger to start the breaker Adequate down pressure is very important When the tool bit breaks through the obstruction or becomes bound release the trigger and reposition the tool bit STANLEY NOTE Partially depressing the trigger allows the tool to run at slow speed Slow speed operation permits easier starting of the tool bit into the work surface 5 To start break an opening hole in the center of the surface After making a hole break portions of the material into the original opening For best produc tivity the breaking should be done around the origi nal hole The size of the broken material will vary with the strength and thickness of the base material and the amount o
