To Add Oil To Pump + DO NOT ATTEMPT TO OPERATE THIS AIR COMPRESSOR WITHOUT FIRST ADDING OIL TO THE CRANKCASE. Serious damage can result from even limited operation unless filled with oil and broken in correctly. Make sure to closely follow initial start-up procedures. COMPRESSORS ARE SHIPPED WITHOUT OIL. A small amount of oil may be present in the pump upon receipt of the air compressor. This is due to plant testing and does not mean the pump contains oil.
INSTALLATION HOW TO SET UP YOUR UNIT Location of the Air Compressor G G G G Locate the air compressor in a clean, dry, and well ventilated area. The air compressor should be located at least 12" away from the wall or other obstructions that will interfere with the flow of air. The air filter must be kept clear of obstructions which could reduce air flow to the air compressor. The air compressor requires fresh air flow for proper cooling. DO NOT ALLOW THE COMPRESSOR TO GET WET.
Extension Cords Use extra air hose instead of an extension cord to avoid voltage drop and power loss to the motor, and to prevent overheating. If an extension cord must be used, be sure it is: • 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 • in good condition • no longer than 50 feet • 12 gauge (AWG) or larger. (Wire size increases as gauge number decreases. 10 AWG and 8 AWG may also be used. DO NOT USE 14 OR 16 AWG.
OPERATION Know Your Air Compressor READ THIS OWNER’S MANUAL AND SAFETY RULES BEFORE OPERATING YOUR UNIT. Compare the illustrations with your unit to familiarize yourself with the location of various controls and adjustments. Save this manual for future reference. Description of Operation Become familiar with these controls before operating the unit.
Dipstick: Indicates the amount of oil in the pump, the + mark indicates full and the - mark indicates oil needs to be added. See Oil paragraphs in the Maintenance section for instructions. Motor Thermal Overload Protector (not shown): The motor has an automatic reset thermal overload protector. Dipstick 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.
3. Plug the power cord into the correct branch circuit receptacle. (Refer to Voltage and Circuit Protection paragraph in the Installation section of this manual.) 4. Open the drain valve fully (counter-clockwise) to permit air to escape and prevent air pressure build up in the air tank during the break-in period. 5. Set the On/Auto/Off lever to "ON/AUTO" position. The compressor will start. 6. Run the compressor for 20 minutes.
MAINTENANCE Customer Responsibilities Before each use Check Safety Valve Daily or after each use Every 8 hours Every 40 hours Every 100 hours ● ● Drain Tank Oil Leaks Check Oil Change Oil ● ● ● ●1 Air Filter 1- more frequent in dusty or humid conditions Unit cycles automatically when power is on. When performing maintenance, you may be exposed to voltage sources, compressed air, or moving parts. Personal injuries can occur.
5. Drain water from air tank by opening drain valve (counter-clockwise) on bottom of tank. Water will condense in the air tank. If not drained, water will corrode and weaken the air tank causing a risk of air tank rupture. 6. After the water has been drained, close the drain valve (clockwise). The air compressor can now be stored. NOTE: If drain valve is plugged, release all air pressure. The valve can then be removed, cleaned, then reinstalled.
Air Filter - Inspection and Replacement Hot surfaces. Risk of burn. Compressor heads are exposed when filter cover is removed. Allow compressor to cool prior to servicing. A dirty air filter will not allow the compressor to operate at full capacity. Keep the air filter clean at all times. 1. Remove the air filter cover. 2. Remove the air filter from filter cover. IMPORTANT: Do not operate the compressor with the air filter removed. 3. Place new air filter into filter cover.
SERVICE AND ADJUSTMENTS Unit cycles automatically when power is on. When doing Maintenance, you may be exposed to voltage sources, compressed air or moving parts. Personal injuries can occur.
