4.1 공기 공급 요구 사항
This tool is air-powered and requires a clean, lubricated air supply. Ensure your air compressor meets the following specifications:
- 공기 흐름 속도: 17 standard cubic feet per minute (SCFM) or 481 liters per minute (LPM) at the tool.
- 공기압: 90 pounds per square inch (psi) at the tool when running with the lever fully depressed.
- Airline: An approved 3/8 inch (10 mm) airline is recommended. Use the minimum length required for the application, with a maximum length of 25 feet (8 m).
4.2 Attaching the Disc Pad
- Ensure the air supply is disconnected from the sander.
- Align the 3M Stikit Disc Pad 20354 with the sander's base.
- Securely attach the disc pad using the provided 24 mm Pad Wrench 28108. The disc pad reduces vibrations and ensures reliable disc adhesion.

5.1 일반 작업
- Connect the sander to the air supply.
- Hold the sander firmly with both hands, ensuring a comfortable grip.
- Place the abrasive disc flat against the workpiece surface.
- Depress the lever to start the sander. The tool operates at a maximum RPM of 12,000 at 90 psi.
- Move the sander in overlapping patterns across the surface to achieve an even finish. The random orbital action helps prevent swirl marks.
- Release the lever to stop the sander.
- Disconnect the air supply when finished or when leaving the tool unattended.

5.2 성능을 위한 주요 기능
- 강력한 모터: The 0.28 hp motor provides ample power for various sanding and finishing applications.
- 원활한 작동: A precision-balanced motor ensures smooth operation, contributing to greater comfort and control.
- Random Orbital Action: The 3/16" diameter orbit rotates the abrasive disc in two simultaneous overlapping oval patterns, preventing single abrasive particles from following the same path twice. This produces a random scratch pattern and a swirl-free finish suitable for paint or varnish.
- 인체공학적 디자인: 로우 프로file, balanced design, comfortable rubber grip, and recessed lever platform are engineered to optimize ergonomics and reduce operator fatigue.
