Dual Control Operation
When electric powered compressors are provided with “Optional” stop/start and constant speed control.
• The constant speed control pilot is to be set to unload at a slightly lower pressure than the pressure switch. That is,
if your pressure switch is set to cut out at 125 PSIG. then the constant speed control pilot should be set to unload at
approximately 120 PSIG.
• An isolation valve is placed in the supply line to the constant speed control pilot. This valve, when open will provide
constant speed operation and when closed stop/start operation. If you close the valve when the compressor is in the
process of unloading, it may stay unloaded in spite of falling pressure. If this occurs, simply open and reclose the valve.
MAINTENANCE
NOTE: Time frames below may need to be shortened in harsher environments.
Daily Maintenance Recommended (8 hours of operation)
1. Check oil level, add oil as required.
2. Drain moisture from tank by opening tank drain cock located in bottom of tank.
3. Turn off compressor at the end of each day’s operation. Shut off air supply by closing valve. Turn off power supply at
wall switch.
Weekly Maintenance
1. Turn power off. Clean dust and foreign matter from cylinder head, motor, fan blades, intercooler and tank.
2. Manually operate the pressure relief valves to insure proper operation.
Monthly Maintenance (160 hours of operation)
1. Remove and clean intake air filters.
2. Check V-belts for tightness (See Checking Belt Tension).
Every 90 Days (500 hours of operation)
1. Change crankcase oil. Use type and grade oil as specified. (See Oil Recommendation and Specification)
2. Check entire system for air leakage around fittings, connections and gaskets.
3. Tighten nuts and cap screws as required.
4. Replace air filter element
Every 180 Days (1000 hours of operation)
1. Check and clean compressor valves, replace springs, discs, and seats when worn or damaged. If Reed valves are used,
inspect them for cracks. Replace if required.
2. If excessive carbon build-up is found. This is an indication that the wrong oil is being used, or the compressor is
overheating.
CAUTION: Valves must be replaced in original positions. Valve gaskets should be replaced each time valves are
serviced.
3. Electric Motor or Gas Engine: For service refer to separate manual or chart attached to equipment.
Once a Year (Every 2000 hours)
1. Inspect pressure switch contacts and operation.
2. Inspect contact points in motor, if so equipped.
3. Inspect the tank for corrosion or other damage.
