R2 Paint Spray Gun

R2 paint spray gun is a pneumatic spray gun commonly used for small area repair and fine spraying, the following is the relevant introduction:

Features: Usually using stainless steel nozzles and needles, fine atomization, paint saving and durability. The spray gun is small and lightweight, and the ergonomic design makes it comfortable to hold, making it less tiring to use for a long time. The adjustment knob is sensitive, and the amount of paint and atomization can be adjusted as needed, and the air pressure adaptation range is wide and can be matched with small domestic air compressors or professional-grade air pumps.

Scope of application: suitable for leather goods and leather shoe coloring care, automobile, furniture, tile repainting repair, and can also be used for painting, wall painting, art creation, and spraying of small objects such as mousse cake coloring.

Main parameters: the paint supply mode is gravity type, the spraying distance is 150mm, the air consumption is 45L/min, the paint spraying volume is 80ml/min, the spraying air pressure is 0.18-0.24MPa, the spray width is 100mm, the air interface is 1/4PF, and the weight is about 260g.

Cleaning and maintenance: The R2 paint spray gun is easy to disassemble and easy to clean, and the parts can be soaked and brushed, dried and properly lubricated before assembly to maintain good spraying results and extend service life

Here are some frequently asked questions (FAQs) about the R2 paint spray gun and their answers:

No paint or less paint: it may be that the air replenishment hole, gas cap and suction pipe of the gun pot lid are blocked, and the blocked part needs to be cleaned; it may also be that there is no paint in the pot, and the paint should be supplemented; Or the thimble stroke is too small, and the paint flow adjustment knob can be rotated to increase the needle valve stroke.

Paint leakage at the nozzle: Causes include the ejector pin sealing nut is too tight and can be properly loosened; There is a foreign object inside the nozzle port, and the nozzle needs to be cleaned; If the nozzle and thimble are not matched or damaged, the nozzle set should be replaced; If the ejector pin return spring is broken or not installed, the spring needs to be replaced or installed.

Abnormal spray width: If the center of gravity of the spray width shape is biased to one side, it may be blocked in the center hole of the air cap or the atomization hole, and the air cap can be cleaned or replaced. If the spray width is split, it may be that the viscosity of the paint is too low and the spraying pressure is too high, and the high viscosity can be adjusted or the pressure can be lowered; It may also be that the inner diameter of the fan control hole is too large, and the nozzle set needs to be replaced; or if the coating is insufficient and the atomized air channel is blocked, paint or clean air channel should be added.

Jump gun: The nozzle may not be tightened or installed, and needs to be tightened or reinstalled; If the gun needle seal kit and gun connection nut are loose, the relevant parts should be tightened; If the paint in the pot is insufficient, the paint should be supplemented; If the nozzle set is damaged, the nozzle set needs to be replaced.

The spray width cannot be adjusted: usually the fan control holes on both sides of the air cap are blocked, which can clean the air cap; It may also be that the spray regulator is damaged or installed incorrectly, and the regulator needs to be replaced or installed correctly; Or the air channel of the control hole on the fan surface of the spray gun is blocked, and the air channel should be cleaned.

Abnormal air pressure adjustment: If the air pressure cannot be adjusted normally or the compressed air is sprayed out of the muzzle as soon as it is connected, the air regulator or air valve may be damaged and needs to be replaced; It may also be that the air valve return spring is broken or not installed, and the spring should be replaced or installed.

In addition, the R2 paint spray gun should be cleaned in time after use. During cleaning, the parts can be soaked and brushed in the order of first removing the spray needle, then removing the spray cap, and finally removing the nozzle, blowing it dry and lubricating it properly before assembly.
