If it has prime and purge open the 4 small taps over the rear left wheel remove air from the spray line and fill with spray. Close them after 10-15 seconds and should be sortedI have only been using the sprayer for a couple of months but today it seems to have the application rate fluctuating wildly and wont stay on the target rate for more than a few seconds.
Anybody any ideas where to start?
Get the o ring for it as well, I had one that wouldnt go back in as it had deformed a bit.Flick it to manual if it stay at constant pressure then you flow meter is up thr swanny. Easy fix in about 2 mins max. It’s a common issue after a few season. You can’t get repair kit rather than a full flow meter. It consists of a new paddle and shaft. Again, easy fit
Get two.Get the o ring for it as well, I had one that wouldnt go back in as it had deformed a bit.
If you have run the sprayer out dry it will be the air in the lines affecting the rate as it acts like an accumulator and the rate control can’t regulate it effectively. Open the taps and purge the lines of air then close and go sprayinghad cleaned suction filter and flushed out pressure filter before spraying, they were almost clean anyway. Had run sprayer right out so will try purging lines. But have sprayed over 2500 litres since then twice and i thought it would have cleared can see the puff of air at nozzles as the boom pipe filled. May have to look at flow rate paddles,
thanks for the help.
Have you done the squirty soapy water trick as per my post? Sounds exactly the same as ours; diaphragm can be intact but if bolts aren’t all equally and sufficiently tight it will leak out of the bolt holesseems like air leak, runs in manual control but pressure drops slowly and i can manually increase to suit. replaced diaphragm in ramsey unit as it was looking worn but not holed. didnt change anything.
Well you have ruled out flow meter. Id follow advice of @alomy75 . Again a simple testseems like air leak, runs in manual control but pressure drops slowly and i can manually increase to suit. replaced diaphragm in ramsey unit as it was looking worn but not holed. didnt change anything.
