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 (P/N 15304, includes a liq-
-
tings).
NITROGEN bottle with an 800 psi/55 bar minimum
charge.(Not included in 31254 kit)
1.
CAUTION
This assembly contains nitrogen under pressure.
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 en-
sure 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).
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 procedure.
6. Install the plug.
ACCUMULATOR CHARGING
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 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
gauge, open snub valve slowly until it reaches the
proper charge pressure (600-700 psi).
NOTE:
4.
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.
