Use of backpack spray
1. Properly install spray parts. Check if there is any air leakage in each connection. When using, first install a water spray test, and then install the medication.
When officially used, the medication should be added first and then water should be added. The liquid level of the medication should not exceed the safe water level line. Before spraying, turn the joystick more than 10 times to raise the air pressure inside the bucket to the working pressure. Do not apply excessive force when pulling the joystick to prevent the chamber from exploding.
3. During the initial filling of liquid medicine, since the air chamber and spray bar contain clear water, the concentration of liquid medicine sprayed in the first 2-3 minutes of spray is low, so attention should be paid to re spraying to avoid affecting the effect of pest control.
4. After the work is completed, the residual medicine in the bucket should be poured out in a timely manner, washed with clean water and drained. At the same time, check whether there is water accumulation in the air chamber. If there is water accumulation, the water joint should be removed to drain it.
5. If the spray is not used in a short period of time, the main parts shall be cleaned, dried and installed, and stored in a cool and dry place. If not used for a long time, all metal components should be coated with butter to prevent rusting.
