CHARGING THE ACCUMULATOR
To check or charge the accumulator the following equip-
ment is required:
• Accumulator tester (Part Number 02835).
• Charging assembly (Part Number 15304)
(includes a guage w/snub valve, hose and tting).
• NITROGEN bottle with a 800 psi/56 bar minimum charge.
1. On charge valves containing 5/8 inch hex locking nuts,
rst 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 ac-
cumulator (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 clock-
wise.
5. Connect the charge tting on the hose to the charge
valve on the 02835 Tester.
6. With the gauge and snub valve attached to the nitrogen
bottle, and with the snub valve closed, open the nitrogen
bottle valve.
NOTE:
It may be necessary to adjust the charge at 650-700
psi/45-48 bar to overcome any pressure drop through
the charging system.
7. While watching the pressure gage open the snub valve
allowing the gauge to read 600 to 700 psi/42 to 48 bar,
close the snub valve on the charging assembly and also
on the nitrogen bottle, remove the charging assembly from
the accumulator tester.
8. Turn the gauge end of the tester fully counterclockwise
to retract the plunger in the chuck. Then remove the tester
from the charge valve.
9.On charge valves containing 5/8 inch hex locking nuts,
tighten the locking nut.
TESTING THE ACCUMULATOR
PRESSURE
1. Follow instructions 1 through 4 under "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.
