How to Use
Press and hold the button for approximately 5 seconds before spraying.
Maintain an appropriate distance between the nozzle and the work surface; the spray strength can be adjusted by changing this distance.
In addition, adjust the water control button: turning it counterclockwise increases the water flow, while turning it in the opposite direction reduces the spray force.
When removing dirt, spray from the outer edge toward the center.
For light contaminants such as oil or paint, slightly reduce the water flow to prevent excessive water output with insufficient spray force.
The adjustment ring is used to regulate water intake; ensure it is positioned correctly and aligned with the center of the nozzle opening.
Any adjustment should remain within the range of the adjustment hole.
If the nozzle becomes blocked, remove it and clean it using a fine bamboo stick or rinse it with another spray gun.
Do not use hard metal needles, as they may damage the nozzle.
Maintenance Method
After each day of operation, or even if the spray gun is used only once, add 3–5 drops of needle oil into the fuel inlet of the spray gun.
This helps prevent rust inside the compression cylinder and the rear section of the cylinder, and ensures the spray gun operates at full efficiency.
For every 5 gallons of spray liquid used, add an additional 5 drops of lubricating oil.
