The pneumatic stapler is operated by which power source?

• A. Electricity
• B. Compressed Air
• C. Hydraulic Fluid
• D. Manual Lever

Answer: (B)

Compressed air powers a pneumatic stapler. When you pull the trigger, air from the shop compressor drives a piston inside the tool, pushing the staple into the wood. The air is delivered at a controlled pressure, often through a regulator and filter, with lubrication to keep the mechanism smooth. This setup gives the tool portability, light handling, and quick operation—ideal for cabinetmaking tasks like fastening thin materials. Electricity powers electric staplers, but this tool relies on air pressure rather than electrical energy. Hydraulic systems use fluid pressure, not air, and a manual lever stapler operates without any compressed-air power.
