4.11  Recharging the accumulator 

 

WARNING 

Recharging must be done according to local 
safety  regulations  for  working  with  pressure 
vessels. 

4.11.1  Establish  a  filling  line  between  the  gas 

pressure valve and a gas tank.  
The  accumulator  charging  kit  contains  a 
pressure gauge and a filling line.  
Remember  that  the  adaptor  from  the  line 
and  to  the  gas  tank  is  country  specific  and 
may need to be sourced separately. 

4.11.2  Open the gas tank valve and the top valve to 

fill the accumulator. 
Close  gas  tank  valve  and  wait  several 
minutes  for  the  new  gas  to  equalize  to  the 
accumulator temperature. 

Measure the gas pressure. 

If the pressure is too low apply more gas. 

4.11.3  If the gas pressure is too high open the side 

valve to relieve gas. 
Close  the  top  valve  when  the  gas  pressure 
is correct. 

4.11.4  Open  the  side  valve,  relieve  the  pressure 

completely  and  remove  the  gas  pressure 
gauge. 

4.11.5  Tighten the plug (18 - 22Nm) using the 6mm 

Allen  key  (hexagonal)  and  mount  the 
threaded end cap by hand.
