4. セットアップ手順
This kit is an accessory for an existing airless paint sprayer. Ensure your sprayer unit is off and depressurized before beginning assembly.
- Connect Main Airless Hose: Securely attach one end of the 50-foot airless paint hose to the high-pressure outlet of your airless sprayer unit. Use appropriate wrenches to ensure a tight, leak-free connection.
- Connect Whip Hose (Optional): If using the whip hose for added flexibility, connect one end to the free end of the 50-foot airless hose.
- スプレーガンを接続します: Attach the Graco Contractor Airless Spray Gun to the free end of the whip hose (if used) or directly to the 50-foot airless hose. Ensure the connection is secure and leak-free. The built-in swivel on the gun handle allows for easier movement.
- Install In-line Filter: The in-line filter is typically pre-installed in the gun handle. Verify it is clean and properly seated. This filter helps prevent tip clogs.
- Install RAC X Spray Tip: Insert the RAC X 517 reversible spray tip into the tip guard on the front of the spray gun. Secure the tip guard by rotating it until it locks into place. Ensure the tip is oriented correctly for spraying (not in the unclogging position).
- Prepare Sprayer Unit: Follow your airless sprayer unit's instructions for filling with paint and priming the system. Ensure all air is purged from the system before spraying.
5. 操作手順
Once the system is primed and ready, follow these guidelines for effective spraying:
- テストスプレー: Always perform a test spray on a piece of cardboard or scrap material to check the spray pattern and adjust pressure as needed.
- 距離を保つ: Hold the spray gun approximately 10-12 inches (25-30 cm) from the surface. Maintain a consistent distance for an even finish.
- 一貫した動き: Move your entire arm, not just your wrist, to keep the gun perpendicular to the surface. Overlap each pass by about 50% to ensure full coverage.
- トリガーコントロール: Begin moving the gun before pulling the trigger and release the trigger before stopping movement. This prevents paint buildup at the start and end of each pass.
- 圧力調整: Adjust the pressure on your airless sprayer unit to achieve a soft, feathered spray pattern without tails (uneven edges). Too low pressure will result in tails; too high pressure wastes paint and increases overspray.
- トリガーロック： Always engage the trigger lock when pausing or moving the gun to prevent accidental discharge.
6. メンテナンス
Proper maintenance extends the life of your equipment and ensures optimal performance.
- 使用後は毎回清掃してください: Immediately after spraying, flush the system with the appropriate cleaning solution (water for latex, mineral spirits for oil-based paints). Follow your sprayer unit's cleaning instructions.
- Gun Cleaning: Disassemble the gun (remove tip, tip guard, and filter) and clean all components thoroughly. The totally enclosed needle design helps eliminate exposure to fluid and extends needle life.
- チップメンテナンス: If the spray tip clogs during use, reverse the tip to clear the obstruction, then return it to the spray position. Clean the tip thoroughly after each use.
- フィルターのクリーニング： Remove and clean the in-line gun filter. Replace if damaged or excessively clogged.
- ホースのお手入れ: Flush the hose thoroughly. Store the hose coiled neatly, avoiding kinks or sharp bends.
- ストレージ： Store the gun and hose in a clean, dry place, protected from freezing temperatures if using water-based materials.
