English Rotate the manual lock unloader lever to the open position to prevent air tank pressure buildup. Rotate manual lock unloader lever to the closed position after starting the engine to allow air tank pressure to build. NOTE: Air will not build in tank when manual lock unloader lever in the open position. H Open H closed SAFETY VALVE This valve (I) is designed to prevent system failures by relieving pressure from the system when the i compressed air reaches a predeter­mined level. The valve is preset by the manu­facturer and must not be removed or modified in any way. AIR INTAKE FILTER a The filter (A) 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. AIR TANK DRAIN VALVEs The drain valve (J) is used to remove moisture from the air tank after the air compressor is shut off. Air tank PRESSURE GAUGE j The air tank pressure gauge (D) indicates air pressure in the air tank. REGULATED PRESSURE GAUGE e The regulated pressure gauge (E) indicates D the air pressure available at the outlet side of the regulator. This pressure is controlled by the regulator and is always less or equal to the air F tank pressure. REGULATOR The regulator knob (F) controls the air pressure coming from the air tank. To Adjust Regulator: 1. Pull regulator knob (F) out to unlock. 2. Turn knob clockwise to increase regulated pressure and counterclockwise to decrease regulated pressure. 3. When desired pressure is shown on the regulated pressure gauge push knob in to lock. Warning: Risk of Bursting. Too much air pressure causes a hazardous risk of bursting. Check the manufacturer's maximum pressure rating for air tools and accessories. The regulator outlet pressure must never exceed the maximum pressure rating. Throttle Control When maxi­mum air tank press­ure is reached and the unloader valve vents air, it activates the throttle control on the engine. This gas saving feature holds the engine at a factory-set idling speed until air pressure in the air tank drops to reset pressure. The unloader valve then reactivates the throttle control and accelerates the engine to full throttle. Low oil shut down sensors The air compressor engine is equipped with low oil shutdown sensors. These are safety devices designed to protect your engine from damage in the event the oil level in the crankcase is below minimum. If the oil in engine gets low while the air compressor is running it will automatically shut down the engine and will not restart until oil is added to the engine. If the oil is low before start-up, the engine will not start until oil is added. 10
