HYDRAULIC SYSTEM REQUIREMENTS

• The hydraulic system should provide a flow of 7-9 gpm/26-34 lpm at an operating pressure of 2000 psi/140 bar. Recommended relief valve setting is 2100-2250 psi/145-155 bar.

• The system should have no more than 250 psi/17 bar backpressure measured at the tool end of the operating hoses. The system conditions for measurement are at maximum fluid viscosity of 400 ssu/82 centistokes (minimum operating temperatures).

• The hydraulic system should have enough heat rejection capacity to limit the maximum oil temperature to 140°F/60°C at the maximum expected ambient temperature.

• The hydraulic system should have a minimum of 25 micron filtration. Stanley recommends using filter

The SK58 Sinker Drill is designed to be used to drill holes in rock such as blast holes.

A rock bit containing carbides is attached to drill steel which is inserted into the tool. The tool incorporates a reciprocating piston and a varible speed hydraulic motor. During the drilling process, the piston hammers on the drill steel and the hydraulic motor rotates the drill steel. It is the pounding and rotating motion of the rock bit that causes the rock to fracture into small cuttings.

It is necessary to extract the rock shavings during the drilling process. If the rock shavings are not extracted, the rock bit will sit on top of the shavings, which in turn, will prevent the rock bit from penetrating into the rock.

On SK58110, SK58120, and SK58310 models, air is introduced into the drill steel via a valve in the tool to blow the rock cuttings out of the hole. On the SK58130 model, water is used to flush out the rock cuttings.

elements sized for a flow of at least 30 gpm/114 lpm for cold temperature startup and maximum dirt holding capacity.

• The hydraulic fluid used should have a viscosity between 100 and 400 ssu/20 and 82 centistokes at the maximum and minimum expected operating temperatures. Petroleum base hydraulic fluids with antiwear properties and a viscosity index over 140 ssu/28 centistokes will meet the recommended requirements over a wide range of operating temperatures.

• 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 long.

• Quick disconnect couplings must conform to NFPA T3.20,15/EHTMA specifications.

PRINCIPLE OF OPERATION

factor for the particular application. Incorrect rotation speed and/or inadequate extraction of the rock cuttings will significantly reduce drilling effectiveness and result in substantially increased drilling time.

The tool can drill up to a 3 in./75 mm hole up to 20 feet/ 6 meters deep in rock. The tool has been used for other applications such as dowel drilling and gas leak detection.

Because the tool has been specifically designed to be operated by an individual, it should never be mounted to and operated from a machine such as a drilling rig or small excavator. If a requirement exists to machine mount the tool, the application must first be approved by Stanley Engineering. Failure to obtain this approval can result in tool failure and void the warranty.

See the "OPERATING INSTRUCTIONS" section of this manual for specific operating instructions.

The air requirements for effective drilling are 30 cfm at 120 psi. The air supply is furnished by an air compressor.

SK58 Sinker Drills are designed to be operated and controlled by one individual. The rotation speed of the drill steel and amount of air introduced into the drill steel is adjusted by the operator based on an experience

Page 9

PREOPERATION PROCEDURES

Preparation For Initial Use

The tool, as shipped, has no special unpacking or assembly requirements prior to usage. Inspection to assure the tool was not damaged in shipping and does not contain packing debris is all that is required.

OPERATING INSTRUCTIONS

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.

Check Hydraulic Power Source

1. Using a calibrated flowmeter and pressure gauge, check that the hydraulic power source develops a flow of 7-9 gpm/26-34 lpm at 1500-2000 psi/105140 bar.

2. Make certain the hydraulic power source is equipped with a relief valve set to open at 2100-2250 psi/145155 bar minimum.

3. Check that the hydraulic circuit matches the tool for open-center (OC) operation.

Check Tool

1. Make sure all tool accessories are correctly installed. Failure to install tool accessories properly can result in damage to the tool or personal injury.

2. There should be no signs of leaks.

3. The tool should be clean, with all fittings and fasteners tight.

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 hose couplers on the tool. It is a good practice to connect the return hose first and disconnect it last to minimize or avoid trapped pressure within the tool.

3. Observe flow indicators stamped on hose couplers to be sure that oil will flow in the proper direction. The female coupler is the inlet coupler.

NOTE: The pressure increase in uncoupled hoses left in the sun may result in making them difficult to connect. When possible, connect the free ends of operating hoses together.

4. Connect the hose from the air supply to the hose on the tool.

Check Trigger Mechanism

1. Check that the trigger operates smoothly and is free to travel between the "ON" and "OFF" positions.

Install Drill Steel & Rock Bit

Use standard 4-1/4 inch shank by 1 inch hex drill steel for SK58110, SK58120 and SK58310 models. Use 4-1/ 4 inch shank by 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.

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.

OPERATING PROCEDURES

1. Observe all safety precautions. Make sure you are wearing eye protection, earing protection, foot protection, and head protection.

Page 10

2. Start the hydraulic supply and turn the circuit control valve to the "ON" position.

COLD WEATHER OPERATION

3. Open the air valve on the tool just enough to permit a small amount of air to flow from the rock bit.

Air flow must be continuous during drilling to avoid clogging of air passages and/ or backflushing of waste products into the drill.

4. Place the rock bit firmly on the surface to be drilled.

5. Grip the handles on the tool firmly and open the hydraulic valve lever slightly to start the tool at a slow speed. Adequate down pressure is very important.

6. 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.

If the tool is to be used during cold weather, preheat the hydraulic fluid at low engine speed. When using the normally recommended fluids, fluid temperature should be at or above 50° F/10° C (400 ssu/82 centistokes) before use.

ROUTINE MAINTENANCE

A very important maintenance practice is to keep the hydraulic fluid clean at all times. Contaminated hydraulic fluid causes rapid wear and/or failure of internal parts.

Periodically apply a light coat of WD40™ between the throttle lever and throttle valve and the motor control knob and motor control valve.

Check the nitrogen charge in the accumulator. If low, recharge the accumulator. See the section titled "ACCUMULATOR CHARGING" found later in this manual.

7. 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.

8. 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.

9. 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.

STORAGE

Disconnect all hoses and wipe the tool clean. Spray the interior of the drive hex and motor plate with WD40™. Also apply a light coat of WD40™ between the throttle lever and throttle valve and the motor control knob and motor control valve.

Store in a clean, dry place.

Page 11

SERVICE INSTRUCTIONS

Good maintenance practices will keep the tool on the job and increase its service life.

A very important maintenance practice is to keep the hydraulic fluid clean at all times. Contaminated hydraulic fluid causes rapid wear and/or failure of internal parts.

Follow the procedures contained in the HYDRAULIC SYSTEM REQUIREMENTS section of this manual to ensure peak performance from the tool. Never disassemble the tool unless proper troubleshooting procedures have isolated the problem to an internal part. Then, only disassemble it to the extent necessary to replace the defective part.

KEEP CONTAMINANTS SUCH AS DIRT AND GRIT AWAY

FROM INTERNAL PARTS AT ALL TIMES.

DO NOT ATTEMPT TO SERVICE THIS TOOL IF YOU ARE NOT THOROUGHL Y TRAINED IN THE PROPER DISASSEMBL Y AND ASSEMBLY OF THIS TOOL. IMPROPER DISASSEMBL Y OR ASSEMBLY MAY RESULT IN BODILY INJURY AND DAMAGE TO THE TOOL. ALWAYS REFER ALL MAINTENANCE TO A QUALIFIED AND TRAINED TECHNICIAN.

Place this assembly over the spring back-up with the protuding end of the latch installation tool inserted into the bore of the motor plate.

3. Using a large mallet, strike the face of the latch removal tool with one swift blow. This should push the retaining ring into place.

Always determine and correct the cause of the problem prior to reassembly. Further wear and tool failure can result if the original cause is not corrected.

PRIOR TO DISASSEMBLY

• Clean the exterior of the tool.

• Obtain a seal kit to replace all seals exposed during

disassembly. Note the orientation of seals before removing them. Install new seals in the same position as original seals.

LATCH AND SPRING SERVICE

1. Obtain Stanley special tools latch removal tool (p/n

05045) and latch installation tool (p/n 05062).

THROTTLE VALVE SERVICE

The throttle valve can be serviced without disassembling the entire tool. Follow the instructions below.

1. Remove the valve lever (8) by unscrewing the locknut (7). Lift out the key (47).

2. Remove the retaining ring (9), washer (10), kap seal (11) and o-ring (6).

3. Remove the inlet flange (35) by unscrewing and removing the 2 capscrews (36). Push the throttle valve (42) out of the accumulator housing toward the inlet flange side. Remove the o-ring (38) and kap seal (37), washer (39), kap seal (40) and o-ring (41).

6. Lift out the idler gear (72) and drive gear (99).

7. Remove the woodruff key (77) and push the drive hex (76) out of the drive motor chamber (75).

8. If it is necessary to remove the latch, refer to the section titled "LATCH AND SPRING SERVICE".

9. If it is necessary to remove the bushings (70 & 71), obtain the following Stanley special tools.

Collet, p/n 05871 - used to remove item 71. Actuator Pin, p/n 05067 - used with p/n 05871 Collet, p/n 5068 - used to remove item 70. Actuator Pin, p/n 05067 - used with p/n 05068 Bearing Installation Tool, p/n 05061 Bearing Installation Tool, p/n 05044

A collet is inserted into the bearing until the lip on the collet is under the bearing. The actuator pin is then inserted into the collet to cause the collet to spread. A puller is installed to the actuator to apply force to pull the bearing out.

Bearing installation tools are inserted into the bearing and then used with an arbor press to press the bearing into the bore. Use of a bearing installation tool ensures a straight bearing to bore installation and correct depth.

6. Test the function of the throttle valve by rotating the valve lever back and forth. The lever should rotate with ease. If it seems the throttle valve is binding, disassemble the throttle valve and inspect the parts for damage. If damage is noted, replace the part(s).

HYDRAULIC MOTOR SERVICE

1. Complete steps 1, 2, 6, and 7 under "ACCUMULATOR HOUSING, FLOW SLEEVE, PISTON, & AUTOMATIC VALVE SERVICE".

2. Unscrew and remove the 3 capscrews (95).

10. Loosen the set screw (86) in the knob (87) and remove the knob. Unscrew and remove the valve guide (88). Reinstall the knob and setscrew and then unscrew the motor control valve (89) to remove it.

INSPECTION AND CLEANING

Inspect and clean all parts as follows:

Cleaning

Clean all parts with a degreasing solvent. Blow dry with compressed air and wipe clean. Use only lint-free cloths.

Drive Motor Chamber

The chamber bores and bottoms around the bushings should be polished and not rough or grooved. If the

Page 13

bushing bores are yellow-bronze, replace them and investigate the cause of wear.

4. Install the woodruff key (77) into the slot in the drive hex.

The flat surfaces around the chamber and bolt holes should be flat and free of nicks or burrs that could cause misalignment or leaks.

Bushings

The inside of the bushings should be gray with some bronze showing through. If significant yellowbronze shows, replace the bushings. Inspect the drive hex and idler gear for corresponding wear and replace as required.

Gears

The drive and idler gears should have straight tips without nicks; square tooth ends and a smooth even polish on the teeth and end faces. Check for cracks between the drive gear keyway and gear tooth root. Replace the gear if cracks are present.

Motor Plate

The surface near the gears should show two interconnecting polished circles without a step.

Drive Hex and Idler Gear Shaft

The surface diameter at the bushing and seal locations must be smooth. Grooves, roughness or a reduced diameter indicate fluid contamination or damaged bushings. If abnormal wear as above occurs (more than normal polishing), replace the drive hex, idler gear and associated bushings.

Also check the hydraulic system for excess contamination in the fluid and for filter condition.

MOTOR RE-ASSEMBLY

5. Lubricate the idler gear (72) and drive gear (99) with clean hydraulic fluid and then install them into the drive motor chamber.

6. Apply grease and install a new o-ring (73) into the groove in the drive motor chamber.

7. Install the motor plate to the drive motor chamber and secure with 2 capscrews (67). Check that the drive hex rotates freely.

ACCUMULATOR HOUSING, ACCUMULATOR, FLOW SLEEVE, PISTON, AND AUTOMATIC VALVE SERVICE

1. Secure the tool in a bench vise, with the “IN” and “OUT” ports up, clamping on the flow sleeve tube

between the side rods. Soft vise jaws are recommended.

2. Remove the pigtail hose assemblies.

b. If the valve body remains in the flow sleeve

tube when the accumulator housing is separated from the tube, proceed with step 9.

9. Skip this step if the valve body remained with the accumulator housing assembly when separated from the flow sleeve tube. Grasp the valve body with one hand and slide the valve body off of the piston and away from the flow sleeve. Use your other hand to prevent the washer, automatic valve, and push pins from falling out. Remove the washer, automatic valve, and 2 push pins. Do not use a magnet to remove the push pins.

10. Slide the piston (29) out of the flow sleeve (31). Slide it toward the accumulator housing end of the flow sleeve.

11. Remove the flow sleeve tube from the vise and position it over a work bench so as to allow the push pins (58) to drop out. Hold a finger over the flow sleeve to prevent it from sliding out of the flow sleeve tube.

Note: The tool is full of fluid and will drip from the

ports when the hoses are removed.

3. Remove the charge valve cap (12) (1-3/8 inch hex). . Loosen the 5/8 inch hex lock nut on the charging valve (14) 1-1/2 turns. Using a small punch, depress the stem in the charge valve to discharge the accumulator completely.

4. Remove the charge valve.

5. Remove the blower tube nut (43).

6. Remove the four side rod nuts (66) (1 inch hex).

7. Using a soft faced mallet, tap on the edges of the motor assembly to drive it from the flow sleeve tube (30).

8. Remove the accumulator housing assembly (46) from the flow sleeve tube by tapping on alternate ends of the side rods (78) with a soft faced mallet. Be careful to prevent the washer (27), valve body (56), automatic valve (32), and push pins (57) from falling out when the accumulator housing assembly is separated from the flow sleeve tube.

a. If the valve body remains in the accumulator

housing assembly, lift the automatic valve and push pins out immediately after the accumulator housing assembly separates from the flow sleeve tube. Set the accumulator housing assembly aside.

12. Holding the flow sleeve tube in one hand, push on the flow sleeve to slide it out of the flow sleeve tube. The flow sleeve may be removed from the flow sleeve tube from either end of the tube. Use extreme care in handling the flow sleeve as it contains very sharp edges which can cut you. If the flow sleeve does not seem to be easily removeable from the flow sleeve tube, do not remove it unless necessary. To assist in the removal of a flow sleeve that has proven difficult to remove, use the following procedures.

a. Place the Stanley special split ring tool (p/n

04908) on top of the Stanley special flow sleeve removal tool (p/n 04910). Place the flow sleeve tube on top of the split rings. Using an arbor press and the Stanley special accumulator cylinder puller tool (p/n 05640) to protect the flow sleeve, push the flow sleeve out of the tube.

13. Obtain the accumulator housing assembly. Insert Stanley special accumulator removal tool (p/n

05639) or a 1/2-20 long threaded rod through the blower tube nut hole and thread it into the top of the accumulator. Tap on the special tool or rod with a mallet to drive the accumulator assembly (22, 23, 24, 25, & 26) out of the accumulator housing. If the valve body is in the accumulator housing it will be driven out along with the accumulator assembly. Make sure the washer (27) between the valve body and accumulator is properly located in its counterbore before driving out the valve body and

Page 15

accumulator. If the washer is not properly located, the parts will be damaged. If the entire accumulator assembly is removed, proceed to step 14. If the accumulator cylinder (22) remains in the accumulator housing, it can be removed using the following procedures.

a. If the entire accumulator assembly was re-

moved, skip this step and proceed to step 14. Assemble the Stanley special accumulator cylinder puller tool (p/n 05640) to a slide hammer containing a 1/2 inch diameter shank. Insert the puller tool into the bottom of the accumulator cylinder so that it seats on the inside lower contour of the cylinder. Hammer the cylinder out of the accumulator housing.

are seated correctly to the accumulator chamber before completing the assembly. Use an arbor press to completely seat the assembly using short movements during the last 1/2 inch/12 mm of travel to gently seat the diaphragm.

4. Apply grease and install a new o-ring (21) into the groove on the accumulator cylinder.

5. Apply grease and install the back-up washer (25) and a new cup seal (26) (lips facing out) in the accumulator chamber counterbore.

6. Apply grease and install new o-rings (101) into the grooves on the tube connector. Install the tube connector into the accumulator chamber.

14. Remove the tube connector (102) by pulling it out of the accumulator chamber.

15. To remove the accumulator chamber and diaphragem (23) from the accumulator cylinder, place the accumulator assembly on Stanley special disassembly tools (p/n 05508 ring and p/n 04910 tube). Place a rag in the bottom of the tube to protect the accumulator chamber when it is removed. Drive the chamber and diaphragm out of the cylinder by tapping on the charge valve end of the chamber with a maller or pushing on it with an arbor press.

16. Squeeze the accumulator diaphragm and slide it off the charge valve end of the accumulator chamber.

17. Remove the cup seal (26) and back-up washer (25) from the accumulator chamber.

18. Remove the air tube (1) (or water tube if applicable).

ACCUMULATOR RE-ASSEMBLY

1. Apply grease and install a new o-ring (100) into the groove on the accumulator chamber. NOTE: This oring was only used on early models. It was eliminated on later models.

FLOW SLEEVE, PISTON, & AUTOMATIC VALVE RE-ASSEMBLY

The best way to assemble the flow sleeve (31), automatic valve body (56) and piston (29) is by using an assembly fixture such as that shown in figure 1. The fixture permits the parts to be stacked vertically during the assembly process. After the parts are stacked, the handle assembly can then be placed on top of the stacked parts and tapped into place.

The assembly fixture shown in figure 1 should be constructed of aluminum or brass and should be at least 3-1/2 in/88 mm high but no more than 8 in/203 mm high.

2. Apply a light coating of WD-40™ to the accumulator diaphragm (23) and accumulator chamber (24). Slide the accumulator diaphragm onto the accumulator chamber from the tube connector (102) end.

3. Use grease or rubber lubricant on the inside of the accumulator cylinder (22) and the outside diameter of the diaphragm. Push the accumulator chamber and diaphragm, tube connector end first, halfway into the accumulator cylinder. Be sure the accumulator diaphragm is free of wrinkles and the seal beads

Figure 1.

1. Lubricate the flow sleeve with clean hydraulic fluid and install it into the flow sleeve tube (30). The flow sleeve has a wide groove around the outside of one end. Install this end first. Then place the flow sleeve tube and flow sleeve on top of the assembly fixture shown in figure 1.

Page 16

2. Apply grease and install an o-ring (21) onto the flow sleeve tube.

3. Apply clean hydraulic fluid and install 4 push pins (58) into the holes in the top of the flow sleeve tube. One end of each push pin contains a machined surface. This surface must be facing up as each push pin is installed. Each push pin must slide freely in or out of the hole. If a push pin does not slide freely or seems to stick, the hole may contain contamination or the top edge of the hole contains a burr. Remove burrs with a deburring tool, clean the hole thoroughly and try the push pin again.

4. Tap the roll pin (33) into the hole on the automatic valve body (56).

11. Install the accumulator assembly over the stem of the piston and down to the top of the automatic valve body.

12. Insert the air tube (1) (or water tube if applicable) into the top of the accumulator ensuring it aligns with the hole in the piston.

13. Use a felt tip marker to place a mark on the accumulator cylinder and the accumulator housing to align the tube connector with the port in the accumulator housing.

14. Apply grease liberally to the o-ring surfaces on the accumulator, automatic valve body, flow sleeve tube and to the bore of the accumulator housing.

5. Apply grease and install an o-ring (21) onto the automatic valve body.

6. Lubricate with clean hydraulic fluid and install 2 push pins (57) into the holes in the valve body. One end of each push pin contains a machined surface. This surface must be facing up as each push pin is installed. Each push pin must slide freely in or out of the hole. If a push pin does not slide freely or seems to stick, the hole may contain contamination or the top edge of the hole contains a burr. Remove burrs with a deburring tool, clean the hole thoroughly and try the push pin again.

7. Lubricate the automatic valve (32) with clean hydraulic fluid and install it into the valve body. The automatic valve must freely slide back and forth. If it does not, the valve body or valve may contain contaminants or the bore of the valve body contains burrs. Remove the push pins and scrub the bore of the valve body with emery cloth and then thoroughly clean the bore, push pin holes and valve. Reinstall the push pins and valve.

8. Grasp the automatic valve body and valve so that one or more fingers are gripping the valve to prevent it and the push pins from falling out when the valve body and valve are turned upside down (roll pin facing down). Place the assembly on top of the flow sleeve making sure the roll pin aligns with the appropriate hole in the flow sleeve.

15. Place the accumulator housing over the top of the accumulator, ensure that the felt pen marks are alligned, and then tap it down until the lower part of the housing covers the o-ring on the flow sleeve tube.

16. Lay the completed assembly on its side being careful to prevent movement of the flow sleeve. Remove the assembly fixture.

17. Place the completed assembly horizontally in a vice with soft jaws, oil ports up, and clamp on the flow sleeve tube.

18. Apply grease and Install a new cup seal (93) with lips facing down, the washer (92), new rod seal (91) with lips facing up, and a new o-ring (90).

19. Install the motor over the side rods and into the flow sleeve tube ensuring the roll pin is correctly aligned with the hole in the flow sleeve and the motor control valve is oriented correctly with the handles.

20. Install the 4 side rod nuts. Tighten in 20 ft lb/25 Nm increments to 75 ft lb/100 Nm in a cross pattern.

21. Apply grease and install new o-rings (44 & 45) to the blower tube nut. Install the blower tube nut to the accumulator housing.

22. Install the charge valve (14).

9. Lubricate the piston (29) with clean hydraulic fluid and install into the top of the automatic valve body. Apply grease and install a new o-ring (28) into the groove in the piston (water flush models only).

10. Install the washer (27), smaller diameter first, over the stem of the piston and onto the automatic valve body.

23. Charge the accumulator with 600 psi/42 bar nitrogen as described in the "CHARGING THE ACCUMULATOR" section of this manual.

24. Apply grease and install a new o-ring (13) onto the charge valve cap (12). Install the charge valve cap.

CHARGING THE ACCUMULA TOR

ACCUMULATOR CHARGING

To check or charge the accumulator the following equipment is required:

• Accumulator tester (Part Number 02835).

• Charging assembly (Part Number 06545) (includes a

regulator, hose and fitting).

• NITROGEN bottle with a 800 psi/56 bar minimum

charge.

1. On charge valves containing 5/8 inch hex locking nuts, first loosen the locking nut 1-1/2 turns.

2. Holding the chuck end of the Stanley tester (p/n

02835), turn the gauge fully counterclockwise to ensure the stem inside the chuck is completely retracted.

3. Thread the tester onto the charging valve of the tool accumulator (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.

4. Advance the valve stem by turning the gauge- end clockwise.

5. Connect the charging assembly to the valve on the tester.

6. Adjust the regulator on the nitrogen bottle to 600 psi/42 bar.

NOTE: It may be necessary to set the regulator at 650-700 psi/45-48 bar to overcome any pressure drop through the charging system.

7. Open the valve on the charging assembly hose. When the tester gauge reads 600 to 700 psi/42 to 48 bar, close the valve on the charging assembly hose and remove the charging assembly.

8. Turn the gauge end of the tester fully counterclockwise to retract the plunger in the chuck. Remove the tester from the charge valve.

9. On charge valves containing 5/8 inch hex locking nuts, tighten the locking nut.

TESTING THE ACCUMULATOR PRESSURE

1. Follow instructions 1 through 4 under "CHARGING THE ACCUMULATOR".

2. Read the pressure on the gauge (pressure should be between 500 & 600 psi/35 & 42 bar.

3. If the pressure is low, recharge the tool.
