การตั้งค่า
Proper setup is crucial for safe and efficient operation. Always refer to the main airless sprayer manual for complete system setup instructions.
- ความปลอดภัยเป็นสิ่งสำคัญที่สุด: Ensure the airless sprayer is turned off and depressurized before connecting or disconnecting any components. Wear appropriate personal protective equipment (PPE), including eye protection, gloves, and a respirator.
- Connect Whip Hose: Attach the 3-foot whip hose to the main 50-foot high-pressure hose. Ensure connections are tight to prevent leaks. The whip hose provides flexibility and reduces fatigue during spraying.
- Connect Spray Gun: Attach the Graco RAC X Contractor Airless Spray Gun to the free end of the whip hose. Hand-tighten securely, then use a wrench to ensure a leak-free connection.
- Install Tip Guard and Tip: Insert the RAC X spray tip into the RAC X Tip Guard. Then, thread the tip guard assembly onto the spray gun. Ensure the tip is oriented correctly for spraying (arrow pointing forward).
- ตรวจสอบการเชื่อมต่อ: Double-check all hose and gun connections for tightness before starting the sprayer.

คำแนะนำการใช้งาน
Once the kit is properly set up and connected to an airless sprayer, follow these general operating guidelines:
- เตรียมระบบให้พร้อม: Follow your airless sprayer's instructions to prime the system with the material to be sprayed. This removes air from the hoses and gun.
- ปรับแรงดัน: Set the sprayer pressure according to the paint manufacturer's recommendations and the specific spray tip being used.
- การทำงานของทริกเกอร์: The Contractor Airless Spray Gun features a smooth, lightweight 2-finger trigger pull. Always engage the trigger lock when not actively spraying to prevent accidental discharge.
- เทคนิคการพ่น: Maintain a consistent distance from the surface and move the gun at a steady pace to ensure even coverage. Overlap each pass by approximately 50%.
- Clearing Tip Clogs: If the spray pattern becomes uneven or stops, rotate the RAC X spray tip 180 degrees to the unclog position, trigger the gun to clear the obstruction, then rotate back to the spray position.
การซ่อมบำรุง
Regular maintenance extends the life of your Graco kit components and ensures optimal performance.
- การทำความสะอาดรายวัน: After each use, thoroughly flush the spray gun and hoses with an appropriate cleaning solution (water for latex, mineral spirits for oil-based paints) until the fluid runs clear.
- Gun Filter: The spray gun features an Easy Out Gun Filter. Regularly remove and clean this filter to prevent clogs and maintain consistent spray performance. The filter is designed to be cleaned from the inside out.
- เคล็ดลับการบำรุงรักษา: Clean the spray tip after each use. Store tips in a tip saver fluid to prevent drying and clogging.
- การดูแลรักษาสายยาง: Coil hoses neatly after cleaning and storage. Avoid kinking or crushing the hoses, as this can damage the internal lining.
- Needle Cartridge: The modular needle cartridge design allows for easy servicing. If the gun begins to spit or leak from the front, the needle or seals may need replacement. Refer to Graco service manuals for detailed instructions.
