English FIG. D 8 Cooling System This compressor contains an advanced design cooling system. At the heart of this cooling system is an engineered fan. It is perfectly normal for this fan to blow air through the vent holes in large amounts. You know that the cooling system is working when air is being expelled. Air Compressor Pump The pump compresses air into the air tank. Working air is not available until the compressor has raised the air tank pressure above that required at the air outlet. Motor Overload Protector The motor has a thermal overload protector. If the motor overheats for any reason, the overload protector will shut off the motor. The motor must be allowed to cool down before restarting. To restart: 1. Set the On/Off switch 1 to OFF and unplug unit. 2. Allow the motor to cool. 3. Plug the power cord into the correct branch circuit receptacle. 4. Set the On/Off switch to ON position. Oil Dipstick The oil dipstick 10 indicates the amount of oil in the pump. Check pump oil daily, see Compressor Pump Oil under Maintenance. Air Intake Filter The filter 12 is designed to clean air entering the pump. To ensure the pump continually receives a clean, cool, and dry air supply the filter must always be clean and the filter intake must be free from obstructions. FIG.

Ensure Regulated Pressure Gauge 3 reads 0 psi. 2. Grasp the hose at the Quick Connect 5 plug and push the plug into the Quick Connect 5 body. Coupler will snap into place. 3. Grasp the hose and pull to ensure coupler is seated. Disconnecting Hoses (Fig. C) WARNING: Risk of unsafe operation.
