The Astro Pneumatic Tool Company Model 4008 is a versatile spray gun designed for a variety of painting, coating, and finishing applications. It is specifically categorized as a "Spray Gun with Cup, Red Handle, 1.8mm Nozzle," indicating its primary function and key physical characteristics.

Function Description:

The Astro 4008 is an air-operated spray gun intended for applying enamels, lacquers, stains, and primers. Its core function is to atomize paint materials using compressed air, allowing for an even and controlled application onto various surfaces. The gun features a two-step trigger design: the first step connects to the air source, ensuring airflow fills the spray gun, while the second step connects the paint material for spraying. This sequential activation helps in achieving consistent spray patterns and preventing paint buildup. The gun is designed for precision, with adjustable controls for fan pattern and fluid flow, enabling users to customize the spray according to the specific requirements of their project. Proper surface and paint preparation, in accordance with the paint manufacturer's instructions, is crucial for optimal results.

Important Technical Specifications:

Model Number: 4008
Product Type: Spray Gun with Cup, Red Handle, 1.8mm Nozzle
Nozzle Size: 1.8mm, which is suitable for a wide range of materials, including thicker coatings.
Operation Pressure: 50-60 psi (pounds per square inch). It is critical not to exceed the maximum air pressure of 60 psi to ensure safe operation and prevent damage to the tool.
Avg. Air Consumption: 7-12 cfm (cubic feet per minute), indicating the volume of air required for continuous operation.
Air Inlet Thread NPT: 1/4", a standard size for air tool connections.
Required Compressor: 3hp (horsepower), specifying the minimum power of the air compressor needed to adequately supply the gun.
Net Weight: 2 lbs (0.91 kg), making it relatively lightweight and manageable for extended use.
Dimensions (W x H): 6-1/2" x 12", providing an idea of its physical size.
Max. Pattern at 8" Distance: 11" (280mm), describing the maximum width of the spray pattern achievable at a typical working distance.
Air Hose Requirement: A 1/4" air hose with a maximum length of 25 ft is recommended. For longer distances, a 3/8" air hose connected to the 1/4" air hose is advised to maintain adequate air supply.

Usage Features:

All-Purpose Design: Suitable for a broad spectrum of painting and coating tasks.
Two-Piece Construction: Features a gun with an exclusive air valve design, contributing to its performance and ease of maintenance.
Fully Adjustable Wide Fan Pattern Control: This allows the user to change the spray pattern from a full, wide fan to a round pattern by turning the pattern control knob. The direction of the fan (horizontal or vertical) can also be adjusted by loosening and rotating the air cap 90 degrees.
Fluid Control Knob: Enables precise adjustment of the fluid flow, from fully closed to open, to achieve the desired atomization and paint coverage.
Air Control Knob: Controls the airflow, allowing users to increase or reduce it by turning the knob clockwise or counterclockwise, respectively.
1 Quart Capacity Dripless Cup: Provides a substantial paint reservoir, reducing the frequency of refills, and is designed to prevent drips.
Proper Spraying Technique Guidance: The manual emphasizes maintaining a consistent distance (6-9 inches) from the work surface, keeping the gun in motion during spraying to avoid paint buildup and runs, and proper trigger activation (starting movement before squeezing the trigger and releasing the trigger before stopping movement) to ensure feathered, blended strokes without overlap or unevenness.
Paint Preparation Instructions: Users are advised to thoroughly mix and thin paint according to manufacturer instructions and strain the material through cheesecloth or a paint strainer to prevent clogs.
Test Spraying: Recommended to set up a target (cardboard or scrap material) to adjust the spray gun for the best pattern and atomization before applying paint to the actual workpiece.
Overspray Protection: Suggests using cardboard shields or masking tape to protect adjacent surfaces from overspray.

Maintenance Features:

Easy-to-Clean Design: The "all-purpose easy-to-clean" description implies that the gun is designed for straightforward disassembly and cleaning, which is crucial for maintaining its performance and longevity.
Parts Breakdown and List: The manual includes a comprehensive parts breakdown diagram and a detailed list of all components with their respective part numbers and quantities. This is invaluable for identifying and ordering replacement parts, facilitating repairs and maintenance.
Air Line Set-Up Recommendations: Provides guidance on connecting to the air supply, emphasizing the use of clean, dry air and recommending the installation of an in-line filter-regulator as close to the tool as possible. This helps protect the internal components of the spray gun from moisture and dirt, extending its lifespan.
Warning Against Lubricators: Explicitly states that lubricators should not be used with spray guns as they can damage the paint finish. This highlights a specific maintenance practice to avoid.
Customer Support: Provides a contact number (1-800-221-9705) for questions concerning product performance or other inquiries, ensuring users can get assistance with troubleshooting or maintenance.
Warranty Information: A 1-year limited warranty covers defective material or workmanship, underscoring the manufacturer's commitment to quality and providing recourse for users in case of product issues.
