6.2.1.0 Check the Series 111 Accumulator Precharge
This procedure is a continuation of "Check the Accumulator Precharge." Steps 1-3 of that procedure should
be preformed before completing this procedure.
The Series 111 Accumulators use the poppet-type valve.
1. Connect the charging kit chuck valve to the accumulator valve stem.
2. With an open-end wrench, turn the locknut counterclockwise on the accumulator valve assembly to open
the valve. Read the pressure on either the high or low accumulator charging kit pressure gage.
• If the pressure reading is other than the required pressure level recorded on the accumulator, go to
the procedure “Change the Precharge Pressure.”
• If the pressure level corresponds to the level recorded on the accumulator label, turn the locknut
clockwise to close the valve and continue this procedure.
3. Open the bleed valve on the accumulator charging kit and remove the chuck valve from the accumulator.
4. Replace the valve stem cap and protective cover on the accumulator.
