How to repair a portable hand sprayer

　　The process of repairing a problematic Portable hand sprayer is to find out the cause of the problem. For example, you may realize that you have been pumping the piston, but it has not returned water or other solutions to the bottle. In this case, the spring may be misplaced or damaged. If the spring is accessible, you can replace it, if not, you can choose to replace the sprayer.

　　If the trigger is normal but the seal fails, you can fix it by running a pump or spraying vegetable oil. Particle collection can cause seal failure, so the oil will lubricate and clear the blockage. You can also prick it with a needle or blow air through the nozzle blocking the opposite tube.

　　How to use the portable hand sprayer

　　Using a portable hand sprayer is very easy; perhaps the most difficult point is to mix the chemicals in the right proportions. Before you grab the sprayer, if possible, put on long pants and sleeves or an apron. Then wear glasses and other protective equipment to prevent chemical substances from coming into contact with your body.

　　Grasp the device, pull the valve to release excess air (if any), and then rotate the cap counterclockwise. Then measure the chemicals according to the instructions, pay attention to the bottle capacity, and then pour the chemicals. Finally, add water according to the required dilution rate.

　　Insert the cover back and turn it clockwise until it is tight. Grasp the handle and pump when spraying where needed.
