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.

5.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 section.

6.Install the plug.

––

Accumulator Tester (Part Number 02835).

tings).

ing procedure.

•NITROGEN bottle with an 800 psi/55 bar minimum charge. (Not included in 31254 kit)

CAUTION

The breaker contains nitrogen under pressure.

1.Remove the plug from the handle or handle pivot.

2.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.

3.Thread the tester onto the accumulator charg- ing 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).

2.Connect the chuck of the charging assembly to the charging valve on the accumulator tester or, if pre- ferred, remove the tester from the charging valve and connect the charging assembly chuck directly to the charging valve.

3.Adjust the snub valve to a charging pressure of

600 psi/42 bar. Note: While watching the pressure gauge, open snub valve slowly until it reaches the proper charge pressure (600–700 psi).

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.When the accumulator is fully charged close the snub valve on the charging assembly hose and re- move the charging assembly chuck from the accu- mulator tester or tool charging valve.

5.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. Install the valve cap.
