New Sprayer Keeps Dribbling!

[Gsi Maintenance]

Hi all, I've brought a new sprayer but no matter what I do it dribbles from the nozzle after taking my finger off the trigger. Any ideas anyone?

 

Here's the sprayer.

 

SG 51 - Backpack manual sprayer

my oregon one does the same !

Has anyone had luck with contacting a technical dept at Stihl or have I got to go back to where I ordered it from?? A sprayer that won't stop when you want it to is as useful as a chocolate teapot! I'd have better control with a watering can!!

I've just bought one of those and it does the same thing. It's not a small dribble either. I thought buying a stihl one would be a safe bet out of the less expensive ones. But apparently not.

I bought an old faithfull 16ltr backpack a couple of years ago, (having been used to CP and Berthoud). It was only twenty or thirty quid. I can't fault it apart from it not being too comfortable (having said that, I got through 5 tanks on tuesday no bother).

 

Stihls new products are so popular these days, I'm hardly surprised. The problem with be in a sticking/leaking o ring somewhere. I had a Berthoud do it a while back, took me ages to find the problem. Best to just replace the hose and lance, if you can be sure that's where the problem is.

Take it back and get your money back, that's not good enough when dealing with chemicals. All sprayers dribble a tiny bit but not a lot. Not fit for purpose if that's the case you are saying. Buy a Solo sprayer instead. Used them loads and are good

Berthoud knapsack with CP 1mt lance

As said, Berthoud or Cooper Peglar are all you can really consider even for just semi pro work.

if you want a good sprayer cp are not bad but examiner at sparsholt raved the bertmonds as you can regulate the psi on back of sprayer. so it is constant all the time and if looked after do not dribble.

i have gone CDA for general spraying cheaper than normal spraying clean no mixing, reverse to put chemical back in container and 5ltrs eqivilant to 10 knapsack full for £50. downside gun is not cheap over £200 for one but a long term investment. if doing a fair bit. and it works all i have sprayed is dead and not come back. also not subject as such to wind as droplets not fine mist so can spray if it is a bit windy. not go back to a normal sprayer for general work messy heavy need full ppe. CDA boots, gloves and visor jobs a goodin.

I've been chatting with Stihl technical dept today Gsi Maintenance. They are aware of the problem with these sprayers. They said that there will be a new lance coming out to fix the problem. The person that I spoke to said that since it is a problem that they are aware of it should be covered under warranty. However there isn't going to be a recall or public announcement when it comes out so all he could suggest was for me to keep checking with my dealer.

In the meantime he suggested that if you raise the nozzle higher than the trigger unit and squeeze the trigger to bleed the air out prior to use. it cures the dribble, while waiting for the fix to come out.
