Model 919

Installation Guide

Tools Needed:

  • Adjustable wrench
  • Level
  • Screwdrivers (flat and Phillips)
  • Pliers
  • Tape measure
  • Pipe thread sealant

Step-by-Step Installation

  1. Choose Installation Location: Select a clean, dry, well-ventilated location on a solid, level floor away from flammable materials.
  2. Unpack and Inspect: Remove all packaging materials and inspect the compressor for any shipping damage.
  3. Position the Compressor: Place the compressor on a level surface with adequate clearance for air circulation (minimum 12 inches on all sides).
  4. Check Oil Level: Verify the oil level is at the proper mark on the sight glass. Add recommended compressor oil if needed.
  5. Electrical Connection: Connect to a properly grounded 120V, 60Hz, 15A dedicated circuit. Use appropriate gauge extension cord if necessary.
  6. Air System Connection: Connect air hoses using appropriate fittings. Apply thread sealant to all threaded connections.
  7. Pressure Settings: Set the pressure regulator to desired output pressure (typically 90-120 PSI for most tools).
  8. Initial Test Run: Run the compressor without load for 10-15 minutes to break in the pump. Check for leaks and proper operation.
Warning: All installations must be performed by a qualified person. Ensure proper ventilation and follow all local electrical codes.

Troubleshooting

Problem Possible Cause Solution
Compressor won't start Power issue, pressure switch fault, thermal overload tripped Check power supply, reset thermal overload, check pressure switch
Low pressure output Air leak, worn piston rings, faulty pressure regulator Check for leaks, inspect piston rings, adjust or replace regulator
Excessive noise/vibration Loose components, worn bearings, improper mounting Tighten all fasteners, check bearings, ensure proper mounting
Oil in air lines Overfilled oil, worn piston rings, wrong oil type Drain excess oil, replace piston rings, use recommended oil
Motor overheats Low voltage, restricted ventilation, excessive cycling Check voltage, ensure proper ventilation, reduce duty cycle
Slow recovery time Worn valves, leaking check valve, undersized piping Replace valves, check check valve, use larger diameter hose

Maintenance Codes & Indicators

  • Red Oil Light: Low oil level - Add recommended compressor oil immediately
  • Thermal Overload Light: Motor overheated - Allow to cool, check ventilation
  • Pressure Gauge Fluctuation: Worn valves or leaking system - Inspect and repair
  • Excessive Condensation: Drain tank daily, check automatic drain if equipped
  • Unusual Knocking: Worn connecting rod or bearings - Professional service required
  • Oil Leaks: Check gaskets, seals, and drain plug - Replace as needed
