Remove all packaging leaving the air compressor on the pallet. 2. Remove and discard the (4) screws holding the air compressor to the pallet.
HOW TO SET UP YOUR UNiT Location of the Air Compressor 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 compressor pump and shroud are designed to allow for proper cooling. The ventilation openings on the compressor are necessary to maintain proper operating temperature. Do not place rags or other containers on or near these openings.
Extension Cords Voltage Protection Certain air compressors can be operated on a 15 amp circuit if the following conditions are met. Instead of using extension cords attach extra air hoses to each other starting at the air outlet. If an extension cord must be used, be sure it is: • and Circuit Refer to the Parts Manual for the voltage and minimum branch circuit requirements. Using extension cords is not recommended.
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. Safety Valve Description of Operation Become familiar with these controls before operating the unit. On/Auto/Off Switch: Turn this switch ON to provide automatic power to the pressure switch and OFF to remove power at the end of each use.
Cooling System (not shown): 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 Compressor Pump (not shown): Compresses air into the air tank. Working air is not available until the compressor has raised the air tank pressure above that required at the air outlet.
4. Move the On/Auto/Off lever to "ON/AUTO" position. The compressor will start. 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. 5. Run the minutes. valve is minimal tank. compressor for 15 Make sure the drain open and there is air pressure build-up in 6. After 15 minutes, close the drain valve (clockwise).
Customer Responsibilities Before each use Check Safety Valve Daily or after Every Every each 40 100 use hours hours Yearly O Drain Tank • Air Filter Air compressor pump intake and exhaust valves O(1) • • 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.
iMPORTANT: Do not operate the compressor with the air filter removed. Water wiU 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, the reinstalled. Air Filter inspection Replacement and Not surfaces. Risk of burn.
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. Before performing any Maintenance or repair, unplug the compressor and bleed off all air 5. Unscrew the check valve (turn counterclockwise) using a 7/8" open end wrench. Note the orientation for reassembly. 6. Using a screwdriver, carefully push the valve disc up and down.
To Replace Regulator 1. Release all air pressure from air tank. See "To Drain Tank" in the Maintenance section. 2. 3. 4. 6. Assemble the regulator and orient as shown. Unplug compressor. Remove the outlet pressure gauge and quick connect (if equipped) from the regulator. Remove the regulator. NOTE: Arrow indicates flow of air. Make sure it is pointing in the direction of air flow. 5. Apply pipe sealant tape to the nipple. 7. Reapply pipe sealant to outlet pressure gauge and quick connect. 8.
Before you store the air compressor, make sure you do the following: 1. Review the "Maintenance" section on the preceding pages and perform scheduled maintenance as necessary. 2. Set the On/Auto/Off "OFF". 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. 7. lever to NOTE: If drain valve is plugged, release all air pressure. The valve can then be removed, cleaned, then reinstalled. 3.
, . Performing repairs may expose voltage sources, moving parts or compressed air sources, moving parts or air sources. Persona[ injury may occur. Prior to attempting unplug the air compressor and bleed off all air tank air - compressed any repairs, pressure. PROBLEM Excessive tank pressure - safety valve pops off. CAUSE CORRECTION Pressure switch does not shut off motor when compressor reaches "cut-out" pressure.
PROBLEM Pressure reading on the regulated pressure gauge drops when an accessory is used. CAUSE CORRECTION It is normal for "some" pressure drop to occur. If there is an excessive amount of pressure drop when the accessory is used, adjust the regulator following the instructions in the "Description of Operation" paragraph in the "Operation Section. NOTE: Adjust the regulated pressure under flow conditions (while accessory is being used). Knocking Noise. Possible defect in safety valve.
PROBLEM Regulator will not shut off air outlet. Motor will not run. CAUSE CORRECTION Damaged regulator. Replace. Motor overload protection switch has tripped. Let motor cool off and overload switch will automatically reset. Tank pressure exceeds pressure switch "cut-in" pressure. Motor will start automatically when tank pressure drops below "cut-in" pressure of pressure switch. Extension cord is wrong length or gauge. Check for proper gauge wire and cord length. Check valve stuck open.
