Supports quick disassembly and cleaning, and after cleaning, it is necessary to lubricate the needle valve, spring, and other components to avoid blockage. 

III. Application Scenario Recommendations

1.Architectural Decoration: Multi-color wall paint, water-based coating, and real stone paint spraying require high flow rate and high coverage efficiency.

2.Industrial Painting: Metal anti-corrosion coatings, photocatalyst spraying, suitable for high-pressure environments.

3.Home Repair: Furniture refurbishment, small-area touch-up painting, recommend lightweight models. 

IV. Key Points for Use and Maintenance

1.Operating Specifications

The recommended spraying distance is 150-250 mm. Move at a constant speed to avoid run-off.

Before use, check the needle valve and sealing ring to ensure there is no air leakage or paint leakage.

2.Cleaning and Maintenance

Immediately clean the paint channel with solvent after each use, focusing on cleaning the nozzle and air cap.

For short-term inactivity, immerse the gun head in the solvent, but avoid soaking the entire gun to prevent the sealing ring from aging.

Regularly apply lubricating oil to moving parts (such as the plunger and spring) to prevent rust.

FAQS:

Question A: How to adjust the spray width of the H-871 spray gun?

Answer A:  The method for adjusting the spray width of the H-871 spray gun is as follows: 

Locate the adjustment knob: Usually, there is a smaller knob on the top of the spray gun. This knob is used to adjust the width of the spray pattern. 

Adjustment method: Rotate the spray width adjustment knob clockwise. The spray width will gradually narrow until a circular cross-section spray width can be obtained; if rotated counterclockwise, the spray width will gradually widen, and an elliptical (fan-shaped) cross-section width spray width can be achieved. The width can be adjusted according to actual needs. 

When adjusting, it is necessary to pay attention that the adjustment range each time should not be too large. You can first make a small adjustment, then conduct a trial spray to observe the spray width effect, and then further fine-tune according to the actual situation until you achieve the desired spray width. At the same time, the spray width will also be affected by factors such as the viscosity of the coating, the air pressure size, and the nozzle diameter. If the adjustment effect of the spray width is not satisfactory, you can also check whether these factors are appropriate and make corresponding adjustments.

Question B: How to adjust the air pressure of the H-871 spray gun?

Answer B: The adjustment method for the air pressure of the H-871 spray gun is as follows: 

Locate the pressure adjustment knob: Usually, there is a knob at the tail of the spray gun, which is used to adjust the air pressure. Some spray guns may also be equipped with an air pressure gauge to facilitate real-time viewing of the air pressure value. 

Adjusting air pressure: According to the usage instructions of the spray gun and actual requirements, turn the air pressure adjustment knob clockwise to reduce the air pressure; counterclockwise rotation will increase the air pressure. Generally, the working air pressure of the H-871 spray gun is between 2 - 4 bars, or approximately 0.2 - 0.4 MPa. 

Spray test and fine-tuning: Before the actual spraying, conduct a spray test on waste material to observe the atomization effect and spraying condition of the coating. If the coating does not atomize evenly, there is dripping or abnormal spray range, it indicates that the air pressure may be inappropriate. Continue to fine-tune the air pressure knob until the desired spraying effect is achieved. 

When adjusting, it is necessary to pay attention that the adjustment range should not be too large each time. You should adjust while observing, and at the same time ensure that the nozzle and needle valve of the spray gun and other components are not blocked or damaged, so as not to affect the effect of air pressure adjustment and the spraying quality.
