To check or charge the accumulator the following
equipment is required:
•
Accumulator tester (Part Number 02835).
•
Charging assembly (P/N 31254—includes a
regulator, hose and fitting).
•
Nitrogen bottle with an 800 psi/56 bar minimum
charge.
1.
On charge valves containing 5/8 inch hex locking
nuts, first loosen the locking nut 1-1/2 turns.
2.
Holding the chuck end of the Stanley tester (P/N
02835), turn the gauge fully counterclockwise 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.
5. Connect the charging assembly to the valve on the
tester.
6. Adjust the regulator on the nitrogen bottle to 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.
7. Open the valve on the charging assembly hose.
When the tester gauge reads 600–700 psi/42–48
bar, close the valve on the charging assembly hose
and remove the charging valve.
8.
Turn the gauge end of the tester fully counterclockwise
to retract the plunger in the chuck. Remove the
tester from the charger valve.
9. On charge valves containing 5/8 inch hex locking
nuts, tighten the locking nut.
TESTING THE ACCUMULATOR
1.
Follow Steps 1 through 4 in “Charging The
Accumulator”
.
2.
Read the pressure on the gauge (pressure should
be between 500–600 psi/35–42 bar).
3. If the pressure is low, recharge the tool.
