Test Procedure (Accumulator Charge Pressure)
Move the machine to a smooth horizontal location.
Lower all of the implements. Engage the parking brake. Stop the engine.

(1) Accumulator (2) Transmission (3) Valve (4) Protector
Remove protector (4). Attach tooling (C6), (C7), (C10), and (C11) to valve (3) .
The accumulator charge pressure at tooling (C7) should be 1725 100 kPa (250 15 psi) when the oil temperature is 20 °C (70 °F). If the pressure of the accumulator is low then the accumulator needs to be charged. Check the accumulator again in order to ensure that the charge is maintained.Charging Procedure
Dry nitrogen is the only gas approved for use in the accumulator. Charging the accumulator with oxygen gas will cause an explosion. This danger will not happen if nitrogen cylinders with standard CGA (Compressed Gas Association, Inc.) Number 580 connections are used. When you order nitrogen gas, be sure that the cylinders are equipped with CGA No. 580 Connections. Do not use color codes or other methods of identification to tell the difference between nitrogen and oxygen cylinders.
A new accumulator should be charged before installation. Do not charge an accumulator that is connected to a power train system. Pressure from the power train oil in the system may interfere with the charging procedure.Gas pressure is variable with the temperature. The accumulator must be at the same temperature as the surrounding air before the accumulator can be charged. Use the following chart for the correct nitrogen charge. Use dry nitrogen.

175-5507 Nitrogen Charging Group (C6) Needle Valve (C7) Pressure Gauge (C8) Regulator (C9) Nitrogen Charging Chuck (C10) Nitrogen Charging Chuck (7) Screw (8) Pressure Gauge
Connect the 175-5507 Nitrogen Charging Group to the nitrogen cylinder at nitrogen charging chuck (C9) .
Make sure that needle valve (C6) is closed. Open the valve on the nitrogen cylinder.

(1) Accumulator (3) Valve (4) Protector
Remove protector (4) from valve (3) of accumulator (1) .
Install nitrogen charging chuck (C10) on valve (3) .
Open the valve handle on nitrogen charging chuck (C10). Use pressure gauge (C7) in order to monitor the nitrogen charge in the accumulator.
Check the temperature of the air around the accumulator. Refer to Table 2 for the correct charging pressure.
Open the valve on the nitrogen cylinder. Adjust screw (7) on regulator (C8) until pressure gauge (8) is at the pressure that will charge the accumulator.
Open needle valve (C6) in order to allow nitrogen to flow into the accumulator.
When the pressures on pressure gauge (C7) and on pressure gauge (8) are identical, turn off regulator (C8) .
If the pressure on pressure gauge (C7) decreases, open regulator (C8) .
Repeat Steps 9 and 10 until you have the following results:
Pressure readings on pressure gauge (C7) and on pressure gauge (8) are identical.
