CHARGING THE SIDE ACCUMULATOR
The tools required to charge the breaker are shown be- low. The 33464 adapter and 33300 adapter assembly can be obtained individually or in a kit (P/N 33465). Note that the adapter and adapter assembly are designed to be used with the 505232 charge hose assembly and
the 28257 accumulator tester which are used with other
Stanley model breakers. When charging the breaker, make sure the tools and charge valve are clean. Dirt can contaminate the charge valve and cause leakage.
1.Remove the protective plug from the accumulator cover.
2.Screw the adapter assembly (P/N 33464) onto the tester (P/N 28257) and tighten it.
3.Hold the chuck end of the tester and turn the gauge fully clockwise until the gauge stops turning. Do not tighten.
4.Screw the tester into the threaded hole, in place of the removed protective plug, by turning the chuck. Do not use the gauge for turning. Tighten the chuck lightly to ensure a good seal.
5.Remove the cap and then turn the charge valve 1 to 2 turns counter clockwise until a pressure is indi- cated on the gauge.
6.If the pressure is correct, turn the charge valve clockwise until it stops and then tighten slightly. Un- screw the tester and reinstall the plug and cap. If the pressure is not correct, proceed to Step 7.
7.Connect the charge hose assembly to the charg- ing valve on the tester. Make sure the valve on the charge hose assembly is closed. Open the valve on the nitrogen bottle.
8.Very slowly open the valve on the charge hose as- sembly and slowly meter the nitrogen into the break- er charge valve until the tester reads the correct charge pressure.
9.When the correct pressure is obtained, close the valve on the charge hose assembly and on the ni- trogen bottle. Turn the charge valve clockwise until it stops and then tighten slightly. Unscrew and remove the charge hose assembly. Unscrew and remove the tester. Apply Loctite™ 242 and reinstall the plug and cap.
