CHARGING THE ACCUMULATOR

ACCUMULATOR TESTING PROCEDURE

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

Accumulator Tester (Part Number 02835).

Charging Kit Assembly (P/N 31254); (includes a regulator, hose and fittings).

NITROGEN bottle with an 800 psi/56 bar minimum charge.

1.Remove the charging valve plug from the post driv- er.

2.Holding the chuck end of Stanley tester (P/N 02835), turn the gauge fully counter-clockwise 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 until pressure is read on the gauge (charg- ing pressure should be 500–700 psi/34–38 bar).

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

6.Install the charging valve cap (or plug).

ACCUMULATOR CHARGING PROCEDURE

1.Perform Steps 1 through 4 of the Accumulator Test- ing 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 tool charging valve and connect the charging assembly chuck di- rectly to the tool charging valve.

3.Adjust the regulator to the charging pressure of 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.

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 of tool charging valve.

6.If the accumulator tester has been used, be sure to turn the gauge-end fully counterclockwise before re- moving the tester from the charging valve of the tool.

7.Replace the O-ring plug.
