Operating instructions
How to Operate the Sprayer
Check to ensure all the parts are available upon unpacking, before
assembling in line with the diagram. 
Before spraying, you shall hold the pumping handle to force its lower end
into the groove of the guide base and turn the handle to remove the pump unit
so as to fill the tank with prepared spray chemical to rated volume, followed
by replacing the pump and pumping to inflate the tank(Make sure the shut-off
valve on Shut position) . When the pressure inside the tank increases, you may
hold-down the shut-off valve to start spot or continual spraying. The nozzle
cap may be varied to select proper spraying type to meet the de-
mands of crops.

About the Pressure Regulating Valve
The Pressure Regulating Valve is an important device to reduce spraying pulse, maintain the constant pressure, ensure even spraying, minimize environmen-tal pollution and enhance the pest control performance.
The Pressure Regulating Valve is normally-closed with its open pressure set at 1.4±0.2bar and close pressure set at 1±0.15bar. When the pressure inside the tank increases to above the set open pressure, the sprayer starts spraying by holding down its shut-off valve. When the pressure is lower than the close pressure, the regulating valve will shut-off by itself and stop spraying. You shall inflate the tank if you desire to proceed to spray.
Note: Residual pressure will be maintained in the tank even upon the finish of spraying due to the regulating valve. Please release the pressure before removing the pump by following the instructions (as given in the Relief Valve) -
Relief Valve
Relief Valve is an important part of the Air-compressed Sprayer. When the pressure inside the tank exceeds the set value, the Valve will open by itself to discharge a certain amount of air quickly to maintain the internal pressure below\ the set value and ensure reliable and safe operation.
Note: You may lift the valve thimble of the relief valve to relieve the residual internal pressure before removing the pump.
