CHARGING THE ACCUMULATOR

ACCUMULATOR TESTING

PROCEDURE

To check or charge the accumulator the following equip- ment is required:

31254 Charge Kit: which includes the following.

•Accumulator Tester (Part Number 02835).

•Charging Assembly (Part Number 15304).

(p/n 15304 includes a liquid fi lled gauge with snub valve, hose and fi ttings.)

•NITROGEN bottle with an 1000 psi/70 bar minimum charge. (Not included in 31254 Charge Kit.)

1.Remove the valve cap assembly from the hammer drill.

2.Holding the chuck end of Accumulator Tester (Part Num- ber 02835) turn the gauge fully counterclockwise to ensure that the stem inside the chuck is completely retracted.

3.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.

4.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 500-700 psi/34-48 bar).

5.If pressure is OK unscrew the gauge-end from the chuck to retract the stem, then unscrew the entire tester assem- bly from the accumulator charging valve. If pressure is low, charge the accumulator as described in the following procedure.

6.Install the protective 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 charg- ing system.

4. Open the valve on the charging assembly hose.

IMPORTANT

If the underwater model is to be used at depths greater than 300 ft/91 m, increase the accumulator charge 40 psi/3 bar for each 100 ft/30 m of depth to offset water pressure.

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 charg- ing 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.Replace the valve cap assembly.

GENERAL SERVICE NOTES

1.If the hammer drill 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 mo- tor assembly.

2.If the handle grips need to be replaced.

a. Remove the old grips and clean the handle.

b. Wash the new grips and the handle clean and dry, sim- ply 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.
