Resumen del manual
The pressure switch (19) starts the motor when the air tank pressure drops below the factory set cut-in pressure and stOpS the motor when the air tank pressure reaches the factory set cut-off pressure. (See specification chart, page 5.) Safety Valve WARNING OVER-PRESSURIZATION OFTHE AIR TANK MAY CAUSE TANK RUPTURE OR EXPLOSION. THE OUTFIT IS PROTECTED FROM THE OVER-PRESSURIZATION BY A SAFETY VALVE. DO NOT ELIMINATE, MAKE ADJUSTMENTS OR SUBSTITUTIONS TO THIS DEVICE. I Illll ,_' ",eAeEl't' VALVE _ ON-AUTOIOFF ., TANK PRESSURF SWITCH Immmm m m AIR OUTLET Figure 2 The pressure switch (19) is pre-set to shut off the motor automatically at the maximum operating pressure. If the )ressure switch does not shut off the outfit at its cul-off _ressure seffJng, the safety valve will protect against Jigh pressure by popping at its pre-set pressure. Motor I:he motor has a thermal ovedoad prOtector.If the motor _verheats for any reason, the overload protector will ;hut off the motor. The motor must be allowed to cool _efore restarting. Turnthe ON-AUTO/OFF switch to the )FF position. Depress the reset button Iocaled on the _nd of the motor. To restart, turn the ON-AUTO/OFF _itch to the ON position. Refer to Figure 1. Note If the overload protector shuts the motor off frequently, check for a possible voltage problem. Low voltage can also be suspected when" 1. The motor does not get up to full power or speed; 2. Fuses blOwout when starting the motor. 3. Lights dim and remain dim when motor is started. ' i .... Note = Avoid using long extension cords. They can cause a power loss to the motor, Add extra air hose instead of extension cords. If an extension cord must be used: -use only a 3-wire extension cord that has a 3-blade grounding plug, and a 3-slot receptacle that will accept the plug on the product. - make sure the cord is in good condition. - the cord should bend longer than 50 feet. -the minimum wire size is 12 gauge (AWG). (Wire size increases as gauge number decreases. 10AWG and 8 AWG mayatso be used, 0o not use 14 AWG or 16 AWG,) Pressure Release Valve The pressure release valve located on the side of the pressure switch is designed to unload air from the com pressor head automaUcally al unit shut off. This protects the motor from starting against air pressure remaining in the compressor head and tubing. When the motor stops running, air will be heard escaping from the valve for a few seconds. When the motor is running, no air should be leaking from the pressure release valve. MAINTENANCE Replacing Air intake Filter A dirty air intake filter will not allow the compressor to operate at full capacity. When the intake filter becomes dirty, oily,or covered with paint overspray, replace it. Do not Operate the compressor with the air intake filter removed. To replace the filter, use needle nosed pliers and pull or pry the old filter out. Replace with new. Refer to Figure 1. Checking Safety Valve WARNING l_ OVER-PRESSURIZATL.qN CAUSING "I_ANK RUPTURE OR EXPLOSION MAY OCCUR 1= THE SAFETY' VALVE DO=S NOT WORK PROPERLy. OCCASIONALLY PULL THE RING ON THE SAF__TY VALVE TO MAKE SURE THAT THE VALVE OPERATES FRE.LY. IF THE VALVE IS STUCK OR DO_S NOT OPERATE SMOOTHLY, IT MUST BE REPLACED. Chan_.;,=, v.. Overfilling with oil will cause premature compressor failure. Do not overfill, Check oil level in the crankcase before each use. The oil level should be even with the top of the fill hole and must not be allowed to be lower than _/8" from the top (6 threads down from the top) at any time. It is recommended that the oil in the base (52) be changed after every 100hours of operation. Todrain the oil,remove the oil drain plug (51) and collect the oil in a Suitable container. Be sure to replace the plug securely before adding new oil. Use a special compressor oil, such as Sears 9-16426 or SAE 20-20W SF motor oil (crankcase oil capacity is 16 fluid ounces). Under extreme winter conditions use SAE 10W oil, Location of Air Compressor Locate the unit in a dry, clean, cool and well ventilated area. The compressor crankcase and head are designed with fins which allow for proper cooling: Clean or blow off fins and any other parts of the compressor that collect dust Ordirt. A clean compressor runs cooler and provides longer service. Do not place rags, contain_ ers or other material on or against the console which would obstruct ventilation openings necessary for prop: er compressor operating temperature. If humidity is high, a Sears Air Filter can be installed on the air outlet adapter to remove excess moisture. Follow the instruclions packaged with the air filter for proper installation. Draining Water From Air Tank WARNING _ IIIII WATER WILL CONDENSE IN THE AIR TANK. IF NOT DRAINED, THE WATER WILL CORRODE AND WEAKEN THE TANK. DRAIN THE TANK AS INSTRUCTED BELOW. Water should be drained from the air tank after eacJi use. Todrain the wamr that has gathered in the air tank, open drain cock valve (43, page 10) and a)low to drain. _en empty, close t...
