Air-powered tools such as the dual-action sander and jitterbug will last longer and require less maintenance if they are

• A. Oiled daily
• B. Oiled after use
• C. Oiled weekly
• D. Oiled monthly

Answer: (A)

Regular lubrication is essential for air-powered tools because it reduces metal-to-metal wear, protects seals, and helps carry away heat and moisture in the compressed air. Oiling daily makes sure lubrication is present with every use, so moving parts like bearings, pistons, and seals stay lubricated during operation. This minimizes friction, prevents rust, and lowers the chance of internal damage, which means the tools run smoother for longer and require less maintenance overall. Oiling only after use or on a weekly or monthly schedule means parts may run dry during use, increasing wear and the potential for breakdowns. Use the recommended oil amount in the air line so a small amount is delivered with each cycle.
