FILLING THE TANK AND ADDING CHEMICAL
Warning : Before using the sprayer for the first time or adding chemical check the operation and function of the
sprayer with clean water.

Check that the filter is clean and all fittings, hoses and gun connections are tight.
Partly fill the sprayer before adding chemical. Always use clean water to prevent blockages and ensure chemical function is
not inhibited.
Add the chemical according to the directions on the chemical container following all safety and protective equipment
recommendations.
Do not use wet powders or chemicals that must remain suspended in solution and require agitation. Only use chemicals or
dyes that fully dissolve.
Do not use a sprayer that has been used to spray herbicides for insecticides or nutrients unless the sprayer has been
thoroughly cleaned including neutralizing the herbicide according to the manufactured directions if required.

OPERATING THE PUMP

The tank is pressurised by manually pumping the handle up and down. A pressure safety valve prevents over pressurisation.
After use always release the air pressure inside the tank using the pressure safety valve, particularly in hot weather.

CLEANING THE FILTER IN THE GUN HANDLE
Use clean water and rinse out the sprayer after use to avoid the filter becoming clogged. The filter is fitted inside the handle
