Charging The Accumulator - Stanley BR5017801 User Manual

CHARGING THE ACCUMULATOR

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 with snub valve, hose and
fittings).
• NITROGEN bottle with an 800 psi/55 bar minimum
charge. (Not included in 31254 kit)
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 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
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 CHARGING
1. Perform Steps 1 through 4 of the Accumulator
Testing procedure.
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 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
remove the charging assembly chuck from the
accumulator tester or tool charging valve.
5. 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. Install the valve cap.
