SAFETY GUIDELINES - DEFINITIONS Safety is a combination of common sense, staying alert and knowing how your compressor works. Read this manual to understand this compressor.
When installing or moving the compressor 7. The compressor should be located where it can be directly wired to a circuit breaker. The compressor should be wired by a qualified electrician. WARNING This compressor is extremely top heavy. The compressor must be bolted to the floor with vibration pads before operating to prevent equipment damage, injury or death. Do Not tighten bolts completely as this may cause stress to the tank welds. Chart 1a. 8.
Follow the safety precautions for electrical connections 1. Follow all local electrical and safety codes, as well as the National Electric Code (NEC) and the Occupational Safety and Health Act (OSHA). 3. Protect wires from contact with sharp objects. 2. Wiring and fuses should follow electrical codes, current capacity and be properly grounded. All electrical connections should be made by a qualified electrician. CAUTION Plan ahead to protect your eyes, hands, face and ears Dress for safety WARNING 1.
Spraying precautions WARNING Never point a spray gun at yourself or any other person or animal. Accidental discharge may result in serious injury. 1. Do Not spray in the vicinity of open flames or other places where a spark can cause ignition. Do Not smoke when spraying paint, insecticides, or other flammable substances.
GLOSSARY OF TERMS Air Filter Pressure Switch Porous element contained within a metal or plastic housing attached to the compressor cylinder head which removes impurity from the intake air of the compressor. Device which automatically controls the on/off cycling of the compressor. It stops the compressor when the cut-off pressure in the tank is reached and starts the compressor when the air pressure drops below the cut-in pressure. Air Tank Cylindrical component which contains the compressed air.
WIRING 1 PHASE START/STOP CONTROL WIRING SCHEMATIC CIRCUIT BREAKER DISCONNECT AUTO OFF PRESSURE SWITCH OPTIONAL OL COIL AUX. LOW OIL LEVEL SWITCH MOTOR STARTING THE COMPRESSOR Prior to actually running the compressor, check the following items: Crankcase oil - Make sure the sight glass shows 1/2 full or slightly above. Make sure all rags, tools, oil, etc. are away from the unit. Operate the compressor for a few minutes unloaded (air system open) then allow the compressor to pump up.
(Gas Drive Models) Please refer to your engine operation manual for proper starting instructions. Gasoline driven compressors are equipped with a cold start valve for loadless starts. Note: In some instances, it still may be necessary lift the toggle on the unloader/pilot valve to relieve the head pressure. See page 11 Battery Connection Instructions for Electric Start Engines Note: Make sure to follow instructions carefully to avoid a short and possible damage to the starter solenoid and/or battery. 1.
TROUBLESHOOTING GUIDE Low discharge 1. Compressor too small pressure for application 2. Air leaks 3. Restricted intake air 4. Blown gasket(s) 5. Broken or misaligned valves Excessive noise “knocking” 1. Loose drive pulley or flywheel 2. Low on oil 3. Worn connecting rod or connecting rod bearing 4. Noisy check valve Excessive oil carryover Water in tank and/or discharge line Will not run or motor hums 1. Worn piston rings 2. Restricted intake air 3. Too much oil in compressor 4.
TROUBLESHOOTING GUIDE (Continued) Pressure switch unloader constantly leaking air Pressure switch not unloading Excessive vibration Overheating 1. Malfunctioning check valve 1. Replace check valve if unloader bleeds constantly. Do not remove check valve with air pressure in tank 1. Malfunctioning pressure switch 1. Replace pressure switch if it does not release air pressure briefly when unit shuts off. Do not remove pressure switch with air pressure in tank 1. Improper installation 1.

Manually Draining an Air Tank: Step 1) Disconnect & lockout the compressor from the power source (electric models) or disconnect the spark plug wire from the spark plug (gas engine models). Step 2) Tank(s) subjected to freezing temperatures may contain ice. Store the compressor in a heated area before attempting to drain moisture from the tank(s). Reduce the air pressure in the tank to 30 PSIG by pulling the pressure relief valve ring.
