HOSE TYPES

The rated working pressure of the hydraulic hose must be equal to or higher than the relief valve setting on the hydraulic system. There are three types of hydraulic hose that meet this requirement and are authorized for use with STANLEY hydraulic tools. They are:

Certified non-conductive – constructed of thermoplastic or synthetic rubber inner tube, synthetic fiber braid reinforcement, and weather resistant thermoplastic or synthetic rubber cover. Hose labeled certified non-conductive is the only hose authorized for use near electrical conductors.
Wire-braided (conductive) – constructed of synthetic rubber inner tube, single or double wire braid reinforcement, and weather resistant synthetic rubber cover. This hose is conductive and must never be used near electrical conductors.
Fabric-braided (not certified or labeled non-conductive) – constructed of thermoplastic or synthetic rubber inner tube, synthetic fiber braid reinforcement, and weather resistant thermoplastic or synthetic rubber cover. This hose is not certified non-conductive and must never be used near electrical conductors.

OPERATION

The recommended hose size is .500 inch/12 mm I.D., up to 50 ft/15 m long and .625 inch/16 mm I.D. minimum, up to 100 ft/30 m.

PRE-OPERATION PROCEDURES

CHECK POWER SOURCE

1. Using a calibrated flow meter and pressure gauge, check that the hydraulic power source develops a flow of 7-9 GPM/26-34 LPM at 1500-2000 psi/105-140 bar.
2. Make certain the hydraulic power source is equipped with a relief valve set to open at 2100-2250 psi/145-155 bar maximum.

INSTALL DRILL STEEL & ROCK BIT
Use standard 4-1/4 inch shank × 1 inch hex drill steel for SK58110, SK58120 and SK58310 models and 4-1/4 inch shank × 7/8 inch hex drill steel for the SK58130 model.
Drill steels are available in a variety of lengths. Start with a short length so that the tool may be operated at a normal standing position. The tool handles should never exceed chest height during operation.

1. Thread a rock bit onto the drill steel.
2. Rotate the latch (61) out and up.
3. Slide the drill steel into the tool.
4. Rotate the latch down being careful not to pinch your fingers. When correctly installed, the collar on the drill steel should be above the bottom of the latch.

CONNECT HOSES

1. Wipe all hose couplers with a clean, lint-free cloth before making connections.
2. Connect the hoses from the hydraulic power source to the tool fittings or quick disconnects. It is a good practice to connect return hoses first and disconnect 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 coupler.
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 increase within the hoses may make them difficult to connect. Connect the free ends of the hoses together.
5. Connect the hose from the air supply to the hose on the tool.

NOTICE: The air supply must be minimum 30 cfm at 120 psi. Supplying less than these specifications may result in inadequate extraction of rock cuttings; cause cuttings to migrate up the drill steel and into the tool and result in tool damage; diminish drilling time; and cause premature wear of the drill bit.

OPERATION PROCEDURES

1. Observe all safety precautions.
2. Install the appropriate tool bit for the job.
3. Start the hydraulic supply and turn the circuit control valve to the ON position.
4. Open the air valve on the tool just enough to permit a small amount of air flow from the tool bit.
   Note: Air flow must be continuous during drilling to avoid clogging of the air passages and/or back-flushing of waste products into the drill.
5. Place the bit firmly on the surface to be drilled.
6. Open the hydraulic valve lever slightly to start the tool at a slow speed. Adequate down pressure is very important.
7. Ensure the rock bit is rotating at a moderate speed (not too fast, not too slow). When starting the hole, it is best to start at a slow impact and rotation speed until the rock bit has carved out a depression in the material being drilled. If the rock bit is not rotating open the hydraulic valve lever further. If the rock bit still does not rotate adjust the motor control knob until rotation is achieved.
8. After the rock bit has carved out a depression in the material being drilled, open the hydraulic valve lever fully. Readjust the motor control knob to obtain a good drilling speed. Adjust the air valve to ensure the cuttings are being extracted from the drill hole.
9. When the bottom of the tool comes within 6 inches of the drill hole, it is time to either add another section of drill steel or replace the existing drill steel with a longer section. Close the hydraulic valve lever but leave the air valve “ON” and then lift the tool with drill steel and rock bit out of the hole. Leaving the air valve “ON” helps prevent cuttings from falling around the bit while the bit is lifted from the hole.
10. When the tool, drill steel and bit have been removed from the drill hole, turn the valve lever “OFF” and turn the hydraulic supply circuit control valve “OFF” before changing the drill steel or rock bit.

COLD WEATHER OPERATION

If the breaker is to be used during cold weather, preheat the hydraulic fluid at low engine speed. When using the normally recommended fluid, fluid temperature should be at or above 50°F/10°C (400 ssu/82 centistokes) before use.
Damage to the hydraulic system or breaker can result from use with fluid that is too thick.

TOOL PROTECTION & CARE

• Make sure all couplers are wiped clean before connection.
• The hydraulic circuit control valve must be in the “OFF” position when coupling or uncoupling hydraulic tools. Failure to do so may result in damage to the quick couples and cause overheating of the hydraulic system.
• Always store the tool in a clean dry space, safe from damage or pilferage.
• 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 circuit flow. This can cause damage to internal seals.
• Always replace hoses, couplings and other parts with replacement parts recommended by STANLEY. Supply hoses must have a minimum working pressure rating of 2500 psi/172 bar.
• Do not exceed the rated flow. Rapid failure of the internal seals may result. See Specifications in this manual for correct flow rate and model number.
• Always keep critical tool markings, such as warning stickers and tags, legible.
• Keep tool bit sharp for maximum drilling performance. Make sure that tool bits are not chipped or rounded on the striking end.
• Never operate a hammer drill without a tool bit or without holding it against the work surface.
• 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.

TROUBLESHOOTING

MAINTENANCE

ACCUMULATOR TESTING PROCEDURE

To check or charge the accumulator the following equipment is required:
31254 Charge Kit: which includes the following:

• Accumulator Tester (Part Number 02835).
• Charging Assembly (P/N 15304) Includes a liquid filled gauge w/snub valve, hose and charge fitting.
• NITROGEN bottle with a 800 psi/56 bar minimum charge. (Not included in 31254 Charge Kit.)

1. Remove the valve cap assembly from the sinker drill.
2. Remove the protective cap and loosen the 5/8-inch hex locking nut on the tool charging valve 1-1/2 turns.
3. Holding the chuck end of Accumulator Tester (P/N 02835) turn the gauge fully counterclockwise to ensure that the stem inside the chuck is completely retracted.
4. Thread the tester onto the accumulator charging valve. Do not advance the gauge-end into the chuck-end. Turn as a unit. Seat the chuck on the accumulator charging valve and hand tighten only.
5. Advance the valve stem of the tester by turning the gauge-end clockwise until a pressure is read on the gauge (charge pressure should be 600-700 psi/42-48 bar).
6. If pressure is OK unscrew the gauge-end from the chuck to retract the stem, then unscrew the entire tester assembly from the accumulator charging valve. If pressure is low, charge the accumulator as described in the following procedure.
   
7. Tighten the 5/8-inch hex locking nut on the tool charging valve. Be careful not to overtighten. Install the protective cap and valve cap assembly.

ACCUMULATOR CHARGING

1. Perform steps 1 through 4 of the accumulator testing procedure above.
2. Connect the chuck of the charging assembly to the charging valve on the accumulator tester or, if preferred, remove the tester from the charging valve and connect the charging assembly chuck directly to the charging valve.
3. Adjust the regulator to the charging pressure of 600 psi/42 bar.
   Note: It may be necessary to set the gauge at 650-700 psi/45-48 bar to overcome any pressure drop through the charging system.
4. Open the valve on the charging assembly hose.
5. When the accumulator is fully charged close the valve on the charging assembly hose and remove the charging assembly chuck from the accumulator tester or tool charging valve.
6. If the accumulator tester has been used, be sure to turn the gauge-end fully counterclockwise before removing the tester from the charging valve of the tool.
7. Tighten the 5/8-inch hex locking nut on the tool charging valve and replace the protective cap.
8. Replace the valve cap assembly.

UNDERWATER MODEL MAINTENANCE

After each use, the movable portions of the tool that were exposed to water should be flushed with a water displacing oil, such as WD40™. Remove water and debris as follows:

1. Turn the tool upside down (without the tool bit) and spray oil through the drive hex and displace any remaining water in the lower cavity.
2. Dip or spray the entire tool.
3. Cycle the tool hydraulically several times before storing away.

GENERAL SERVICE NOTES

1. If the breaker is repainted after servicing, be sure to mask off the vent in the valve cap assembly. Do not allow paint to enter the IN and OUT ports or the bore of the foot assembly.
2. If the handle grips need to be replaced.
   • Remove the old grips and clean the handle.
   • Wash the new grips and the handle clean and dry, simply push or drive the grips on. DO NOT lubricate the parts. The grips will not be secure on the handle if any grease or oil is used.

UNDERWATER TOOLS DEPTH GUIDELINE

UNDERWATER MODELS ONLY

CAUTION: Do not use hydraulic tools underwater that are not designated as an “underwater” model, or this will result in damage to the tool.

For underwater hydraulic tools the applications are broken down into four quadrants depending on type of tool and method of operation.
The types of tools are percussive and rotational, each with different characteristics allowing for different depth operation. With percussive tools, the nitrogen accumulator PSI must counter the increase in ambient pressure found at lower depths. Since there is a maximum PSI for percussive tools they are limited to certain depths. Rotational tools do not have accumulators and thus are capable of deeper depths.
The methods are broken into diver operated or remote operated vehicle (ROV). ROV’s can reach lower depths and with an onboard hydraulic power source that is depth compensated, can operate hydraulic tools at depths of thousands of feet. ROV operation is still limited to the tool, for example a percussive tool has the same depth limitation whether ROV or diver operated.
