User Manual & Installation Guide

919 Series

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 with adequate clearance for maintenance and operation.
  2. Prepare the Surface: Place the compressor on a solid, level surface capable of supporting its weight during operation.
  3. Check Oil Level: Before first use, check the oil level in the pump and add recommended compressor oil if necessary.
  4. Electrical Connection: Connect to a properly grounded 120V, 15A, AC outlet with correct circuit protection. Do not use an extension cord.
  5. Air System Setup: Connect air hoses using appropriate fittings. Apply thread sealant to all threaded connections.
  6. Pressure Settings: Adjust pressure switch to desired cut-in and cut-out pressures according to your application requirements.
  7. Initial Run: Run the compressor without load for 30 minutes to break in the pump, then check for leaks and proper operation.
Warning: All installations must be performed by a qualified person. Ensure proper ventilation to prevent carbon monoxide buildup when operating in enclosed spaces.

Key Features

Oil-Lubricated Pump

The oil-lubricated pump provides superior durability and longer life compared to oil-free models, with smoother operation and better heat dissipation.

ASME Certified Tank

The 20-gallon ASME certified tank meets strict safety standards and includes a lifetime warranty against defects in materials and workmanship.

Thermal Overload Protection

Built-in thermal overload protection automatically shuts off the motor if it overheats, preventing damage and ensuring safe operation.

Low Oil Shutoff

Automatic low oil shutoff protects the pump from damage by stopping operation when oil levels fall below safe operating limits.

Dual Voltage Capability

Can be configured for either 120V or 240V operation, providing flexibility for different workshop setups and power requirements.

Quick-Connect Coupler

Industrial-style quick-connect coupler allows for fast tool changes without tools or complicated disconnections.

Troubleshooting

Problem Possible Cause Solution
Compressor won't start Power issue, pressure switch fault, thermal overload Check power supply, reset thermal overload, check pressure switch
Low pressure output Air leaks, worn rings, intake filter clogged Check for leaks, inspect pump rings, clean or replace air filter
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, incorrect oil type Check oil level, inspect rings, use recommended compressor oil
Frequent cycling Air leaks, faulty check valve, undersized tank Check for leaks, inspect check valve, verify tank size for application
Motor overheats Low voltage, restricted ventilation, excessive cycling Check voltage, ensure proper ventilation, reduce duty cycle

Maintenance Schedule

  • Daily: Drain moisture from tank, check oil level
  • Weekly: Check for air leaks, inspect hoses and connections
  • Monthly: Clean air filter, check belt tension (if applicable)
  • Every 3 Months: Change compressor oil, inspect valves
  • Annually: Replace air filter, inspect safety valve, complete system check
  • As Needed: Replace worn parts, repair leaks, service motor
