1. **What is a piston air compressor?**  
A piston air compressor is a machine that converts power into pressurized air by using reciprocating pistons. It's ideal for powering pneumatic tools like nail guns, paint sprayers, and staplers during construction or renovation projects.  
 
 2. **What tools can this compressor support?**  
It works with most low-to-medium air-demand tools, including:  
- Nail guns (framing/finishing)  
- Airbrushes  
- Impact wrenches  
- Blowguns for cleaning  
 
3. **How often should I maintain it?**  
- **Daily:** Drain moisture from the tank.  
- **Monthly:** Check oil levels (if oil-lubricated) and clean air filters.  
- **Annually:** Inspect valves and seals for wear.  
 
 4. **Can it be used indoors?**  
Yes, but ensure proper ventilation due to noise (typically 70-90 dB) and heat emission. Wear ear protection if needed.  
 
 5. **What safety precautions are required?**  
- Always release tank pressure before servicing.  
- Keep away from flammable materials.  
- Use a regulator to match tool PSI requirements.
