10. ACCUMULATOR

The  accumulator  is  installed  at  the  safety
valve.  When  the  boom  is  left  the  raised
position, and the control levers are operated
with  the  engine  stopped  the  pressure  of  the
compressed  nitrogen  gas  inside  the
accumulator  sends  pilot  pressure  to  the
control valve to actuate it and allow the boom
and  bucket  to  come  down  under  their  own
weight.
