parts when the unit is connected to electrical power. Always have compressor safety guards in place before turning compressor on. 13. use approved air hose. Never use plastic or PVC pipe (unless specified for Air Compressors) to carry air under pressure. Regardless of its pressure rating, it can burst under pressure. Use only metal pipe. 14. Never plug the power cord of this product into an electrical outlet while standing on a wet or damp surface. 15. THiS AiR COMPRESSOR MAY REqui RE A dEdi

SYMbOLOGY To extend the life of your air tools and equipment, we recommend installing an oiler and water filter in series with the Air Outlet Valves (4) of the Air Compressor. (See Figure C.) AiR TO COMPRESSOR TOOL OR OiLER WATER EquiPMENT FiLTER FiGuRE C ASSEMbLY iNSTRuCTiONS To Attach A Power Cord Plug: The Power Cord (31) requires the attachment of a 240 volt, grounded, 3-Prong Plug (not included).

outlet that is properly grounded. To Attach Quick Connectors: Prior to use, the Air Compressor requires the attachment of a 1/4” NPT Quick Connector (not included) to each of its two Air Outlet Valves (4). To do so, wrap approximately 4” of pipe thread sealant tape (not included) around the male threads of the Quick Connectors. Then, firmly screw the Quick Connectors into the Air Outlet Valves.

3. Once the Oil Fill Cap (28) is removed, fill the Air Compressor with a premium quality, 30 weight, non-detergent oil until the level of the oil rises to the midway point in the Oil Level Indicator (35). Then, screw the Oil Fill Cap back onto the Oil Fill Hole. (See Figure d.) To Mount The Air Compressor: 1. For added safety, it is recommended that the Air Compressor be mounted on a flat, level, sturdy, concrete floor surface capable of withstanding the weight of the Air Compressor and a

6. If using only one of the two Air Outlet Valves (4), attach an air hose (not included) to the Air Outlet Valve. Then, attach the other end of the air hose to the pneumatic tool that will be used. If using both Air Outlet Valves simultaneously, attach an air hose to each Air Outlet Valve. Then, attach the other ends of the air hoses to their respective pneumatic tools. (See Figure E.) To Start The Air Compressor: 1. Plug the Power Cord Plug (31) into the nearest 220 volt, grounded, elec

5. Check to make sure the pneumatic tools that will be used are turned off and properly connected to their air hoses. 6. Once the Pressure Gauge (5) has reached at least 80 PSI, turn the Lever on the Air Outlet Valve (4) forward to its open position in order to supply air to the pneumatic tool. If both Air Outlet Valves are being used, turn both Levers forward to their open positions. (See Figure E.) 7. iMPORTANT: Both Pressure Gauges (5) should always indicate the same PSI reading, mean
