Hi. We suggest a maximum of 10mtrs of hose. No longer otherwise the performance and life of the pump will be reduced. We also recommend cleaning the sprayer fully after each use.

Hi Anthony. Thanks for the feedback. Please check that the bell-shaped suction pickup is flat on the bottom of the tank, ensuring it has the best chance of drawing up all the fluid. When you know you are at the last few litres of the tank, try your best to prevent the fluid sloshing about by staying upright and limiting movement. Leaning slightly towards the battery side of the tank will also give you the bast chance of utilising the tanks contents. For further advice please contact: [email protected]

Hi there. Thanks for reaching out. Yes, run time approximately 8 hours. And they're designed for on road use i.e. bitumen. Hope this helps

Hi Jessica. It could possibly be assembled incorrectly. Can you make sure the filter is on gun end.

Hi. Thanks for the message. Are you able to send us photographs of the depressor dial and nozzle to [email protected] please?

Actually it looks exactly like the one I found on your video from 26 April 2022. Do you still need photos? Thank you

@@Pip7-px3wq Yes, if you could still send photographs that would be great. Please send to [email protected]

Hi Anthony. The Sprayer activates only once the trigger is squeezed. Hope this helps.

@@Silvan_Spraying_Specialists Gee, does that actually answer the question that Anthony posted. "The Sprayer activates only once the trigger is squeezed." Do you mean the pump only runs when the trigger on the boom is squeezed, or is the pump running constantly?

Hi there. Unfortunately keys are not sold as replacement parts. You will require a new cap that comes with keys

Hi Matt. The flat fan is not adjustable. Nozzles supplied in the kit are Flat fan, Adjustable and Air induction.

Hi Glen, The pressure (psi) is not adjustable on the WP12-1 rechargeable knapsack However a range of nozzles is supplied with the sprayer to cater for different spray applications -An adjustable cone nozzle can be used as a general nozzle. It can be adjusted to a fine mist for insecticide applications of a coarse pattern for herbicide applications -A yellow fan jet can be used for general herbicide spraying -The blue nozzle is an air inducted herbicide nozzle to reduce drift. We also have available an optional spray shield that can be purchased for spraying around sensitive plants to prevent herbicide drift

Hi Shirley, The lid screws off just like unscrewing the lid of a jar. Click the handle into the guides on the top of the lid, keep the tank steady and then unscrew the lid. If this isn't working please email us at [email protected] with a photo of the lid.

The pump should be serviced if you are having trouble building or maintaining air pressure in the sprayer.

Hi there, please visit our website Instruction Manuals page here: www.silvan.com.au/instruction-manuals/ The manual can be found under 'Selecta' > 'Workshop & Maintenance'.
