Hand-held sprayer operation method

        Sprayer: Hand-held sprayer operation method

        (1) Installation: Assemble each part according to the instruction manual, and pay attention to the correct position of each part during installation. Do not overtighten the connecting parts of the plastic sprayer to avoid breakage.

        (2) Test spray: add a small amount of clean water into the liquid tank, pump up to the proper pressure and test spray. Check whether there is air or water leakage at each connection, and whether the spray is normal.

        (3) Liquid medicine: filter the prepared liquid medicine and pour it into the barrel. The liquid medicine should not exceed the standard line to keep a proper space in the barrel to store compressed gas.

        (4) Air pump: Install the pump body and screw it tightly so that air can be pumped without leaking air or water. Some sprayers have an adequate pressure and automatically exhaust. If there is no exhaust device, the air pressure should not be too high.

        (5) Spray: The size of the droplet is related to the pressure intensity, and the nozzle can be adjusted to spray according to the target and environment to be killed.
