Installation Guide
Tools Needed:
- Adjustable wrench
- Pressure gauge
- Screwdrivers (flat and Phillips)
- Pliers
- Teflon tape
Step-by-Step Installation
- Choose Installation Location: Select a clean, dry, well-ventilated location on a solid, level surface away from flammable materials.
- Unpack and Inspect: Remove all packaging materials and inspect the compressor for any shipping damage.
- Add Oil: Check oil level and add recommended compressor oil if necessary (for oil-lubricated models).
- Connect Air Hose: Attach air hose to the compressor outlet using appropriate fittings and Teflon tape for sealing.
- Electrical Connection: Connect to a properly grounded 120V, 15A, AC outlet with correct circuit protection. Do not use an extension cord.
