Accumulator Recharging Procedure

Accumulator is charged with nitrogen under high 

pressure. This pressure must be unloaded before 

dismounting.
Failure to observe this warning could result in 

severe injury or death.

   1.  Check that the oil inlet of the accumulator is 

depressurized.

  2.  Remove the protective cap over the charging 

screw (9) of the accumulator. The socket head 

screw must be perfectly clean.

  3.  Loosen the charging screw on top of the accumu-

lator (maximum of two turns). Totally neutralize the 

pressure before dismounting the accumulator.

  4.  Unscrew the accumulator cover (10), take out 

the diaphragm (11), and check for leakage and 

damage.

  5.  Clean, check, and replace damaged or worn 

parts.

  6.  Grease the seal faces of the accumulator body 

(12) and the accumulator cover (10) with silicone.

  7.  Spray both sides of the diaphragm with silicone. 

Place the diaphragm with its bead pointing down-

ward so that it fits in the groove of the accumula-

tor body (12).

  8.  Unscrew the charging screw and replace the seal 

ring (13).

  9.  Grease the thread of the accumulator cover (10) 

with copper grease and tighten to approximately  

300 Nm (221 ft-lb).

10.  Fasten the charging screw lightly, and loosen it 

two turns afterward.

11.  Mount the filling device on the filling socket of 

the accumulator cover and fasten it lightly while 

turning the handle (2) forward and backward, 

ensuring that the hexagon resiliently fits into the 

charging screw.

12.  Close the bleeder valve (5) by turning it clockwise.
13.  Connect the hose (7) to the check valve (6).
14.  Connect the free end of the hose directly to the 

nitrogen bottle by using the reducing nipple.

Note:  Use only pure nitrogen.

15.  Read the pressure on the gauge (4). Carefully 

open the valve of the nitrogen bottle (1) and 

charge with nitrogen until the pressure is approxi-

mately 20% higher than required charging pres-

sure. Close the valve of the nitrogen bottle.

16.  If the gauge (4) shows too high a nitrogen pres-

sure, loosen the bleeder valve (5) until the required 

pressure is achieved.

17.  Close the charging screw (9) of the accumulator 

by turning the handle (2) clockwise.

18.  Unload the nitrogen hose by opening the bleeder 

valve (5).

19.  Dismount the filling device and check the charging 

screw (9) for leakage with drops of oil.

20.  Fit the protective cap over the accumulator.
