When the air compressor reaches “cut-out” pressure, the check valve “closes”, allowing air pressure to remain inside the air tank. ON/AUTO - OFF Switch (C) Fig. 3: Turn this switch ON to provide power to the automatic pressure switch and OFF to remove power at the end of each use. Pressure Switch (D) Fig. 1: The pressure switch automatically starts the motor when the tank pressure drops below the factory set “cut-in” pressure. It stops the motor when the air tank pressure reaches the factory set “cut-out” pressure. Regulator (E) Fig. 3: The air pressure coming from the air tank is controlled by the regulator. Turn the regulator knob clockwise to increase pressure and counterclockwise to decrease pressure. To avoid minor readjustment after making a change in pressure setting, always approach the desired pressure from a lower pressure. When reducing from a higher to a lower setting, first reduce to pressure less than that desired, then bring it up to the desired pressure. Depending on the air requirements of each particular accessory, the outlet regulated air pressure may have to be adjusted while operating the accessory. Outlet Pressure Gauge (F) Fig. 3: The outlet pressure gauge indicates the air pressure available at the outlet side of the regulator. This pressure is controlled by the regulator and is always less than or equal to the tank pressure. See “Operating Procedures”. Fig- 3 6 Tank Pressure Gauge (G) Fig. 3: The tank pressure gauge indicates the reserve air pressure in the tank. 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 Intake Filter (H) Fig. 1: This filter is designed to clean air flowing into the pump. This filter must always be clean and free from obstructions. Twist filter cover counter-clockwise to remove and expose paper filter element. Drain Valve (J) Fig. 2: The drain valve is located at the base of the lower air tank and is used to drain condensation at the end of each use. Motor Thermal Overload Protector: The electric motor has an automatic thermal overload protector. If the motor overheats for any reason, the thermal overload protector will shut off the motor. The motor must be allowed to cool before restarting. Pressure Release Valve: The pressure release valve located on the side of the pressure switch, is designed to automatically release compressed air from the compressor head and the outlet tube when the air compressor reaches “cut-out” pressure or is shut off. If the air is not released, the motor will try to start, but will be unable to. The pressure release valve allows the motor to restart freely. When the motor stops running, air will be heard escaping from this valve for a few seconds. No air should be heard leaking when the motor is running, or continuous leaking after unit reaches cut-out pressure. Safety Valve (K) Fig. 3: If the pressure switch does not shut off the air compressor at its cutout pressure setting, the safety valve will protect against high pressure by “popping out” at its factory set pressure (slightly higher than the pressure switch cut-out setting). if the safety valve does not work properly, over-pressuri-zation may occur, causing air tank rupture or an explosion. Daily pull the ring on the safety valve to make sure that the safety valve operates freely. If the valve is stuck or does not operate smoothly, it must be replaced with the same type of valve. INSTALLATION AND BREAK-IN PROCEDURES LOCATION OF THE AIR COMPRESSOR Your compressor comes to you completely assembled and ready for use. Operate the air compressor in a dry, clean, cool and well ventilated area. The air compressor pump and case are designed to allow for proper cooling. Clean or blow off dust or dirt that collects on the air compressor. A clean air compressor runs cooler and provides longer service. The ventilation openings on your air compressor are necessary to maintain proper operating temperature. Do not place rags or other containers on or near these openings. VOLTAGE AND CIRCUIT PROTECTION See SPECIFICATIONS Section of this manual. 7 GROUNDING INSTRUCTIONS The air compressor is equipped with a cord having a grounded wire with an appropriate grounding plug. The plug must be used with an outlet that has been installed and grounded in accordance with all local codes and ordinances. The outlet must have the same configuration as the plug. See illustration. DO NOT USE AN ADAPTER. MWIlllfl IMPROPER GROUNDING CAN RESULT IN SEVERE ELECTRICAL SHOCK. Inspect the plug and cord before each use. Do not use if there are signs of damage. Do not modify the plug that has been provided. If it does not fit the available outlet, the correct outlet should be installed by a qualified electrician. If these grounding instructions ...
