10.9 Cut & hold accumulator pressure
The cut & hold is held open by a hydraulic accumulator which is primed as the cut &
hold is closed. If for whatever reason the pressure drops, it will prime again the next
time the cut and hold is closed. If the
991 High Speed
is used on a tractor with high oil
pressure and is then changed to a tractor with a lower oil pressure then the accumulator
may need to be discharged if the cut and hold is not closing fully.
10.9.1 To decrease accumulator pressure
1.
Place a spanner on the banjo bolt, but do not turn the bolt.
2.
Wrap the spanner and bolt with a cloth to stop the oil spray then turn the bolt a
half turn. This should allow the oil to leak out and reduce the pressure. If no oil
leaks then turn the spanner a quarter turn at a time until it leaks off the oil
pressure.
3.
Tighten the banjo bolt once the oil pressure is reduced.
4.
Once the cut and hold is operated again the accumulator will be charged
automatically to the correct pressure.
