11.10 Cut & hold accumulator pressure
The cut & hold is held open by a hydraulic accumulator which is primed before leaving
the factory. If, for whatever reason, the pressure drops or increases it is possible to
prime the circuit again, as follows.
11.10.1 To increase accumulator pressure
1.
Remove the blanking cap on the hydraulic cylinder
2.
Remove the cut & hold feed pipe (and adaptor) and fit it to the open port
3.
Operate the cut and hold to prime the system. It only needs a small amount of
oil to prime it back up.
4.
Remove the hydraulic pipe (and adaptor) and refit it to its original position
5.
Replace the blanking cap on the priming port. Operate the cut and hold to
ensure it is opening and closing. Repeat if it is not fully primed.
