Charging The Accumulator - Stanley BR45 User Manual

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
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)
This assembly 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 entire
tester assembly from the accumulator charging
valve. If pressure is low, charge the accumulator as
described in the following paragraph.
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

CHARGING THE ACCUMULATOR

(P/N 15304) (15304
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.
UNDERWATER MODEL
PREVENTATIVE MAINTENANCE
After each use, the movable portions of the tool that
were exposed to water should be flushed with a water
displacing oil such as WD40™. Remove any remaining
water and debris as follows:
1. Turn the tool upside down (without the tool bit) and
spray oil through the drive hex and side holes in the
breaker foot assembly to displace any remaining
water in the lower piston cavity.
2. Spray oil into the On/Off valve trigger slot area.
3. Dip or spray the entire tool.
4. Cycle the tool hydraulically several times before
storing away.
