RISK OF BURSTING AIR TANK: THE FOLLOWING CONDITIONS COULD LEAD TO A WEAKENING OF THE TANK, AND RESULT IN A VIOLENT TANK EXPLOSION AND COULD CAUSE PROPERTY DAMAGE OR SERIOUS INJURY. WHAT CAN HAPPEN HOW TO PREVENT IT 1. FAILURE TO PROPERLY DRAIN CONDENSED WATER FROM THE TANK, CAUSING RUST AND THINNING OF THE STEEL TANK. DRAIN TANK DALLY OR AFTER EACH USE. IF TANK DEVELOPS A LEAK, REPLACE IT IMMEDIATELY WITH A NEW TANK OR REPLACE THE ENTIRE COMPRESSOR. 2. MODIFICATIONS TANK.
RISK OF ELECTRICAL SHOCK WHAT CAN HAPPEN HOW TO PREVENT IT YOUR AIR COMPRESSOR IS POWERED BY ELECTRICITY. LIKE ANY OTHER ELECTRICALLY POWERED DEVICE, IF IT IS NOT USED PROPERLY IT MAY CAUSE ELECTRIC SHOCK. NEVER OPERATE THE COMPRESSOR OUTDOORS WHEN IT IS RAINING OR IN WET CONDITIONS.

DO NOT REACH AROUND ATTEMPT MAINTENANCE ALLOWED TO COOL.
Become familiar with these terms before operating the unit. CFM: Cut-In Pressure: While the motor is off, air tank pressure drops as you continue to use your accessory. When the tank pressure drops to a certain low level the motor will restart automatically. The low pressure at which the motor automatically restarts is called "cut-in" pressure. Cubic feet per minute. SCFM: Standard cubic feet per minute; a unit of measure of air delivery. PSIG: Pounds per square inch gauge; a unit of measure of pressure.
HOW TO SET UP YOUR UNIT Location 4. 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.
Know Your Air Compressor READ THIS OWNER'S MANUAL AND SAFETY RULES BEFORE OPERATING YOUR UNIT.

Make sure the drain valve is open and there is minimal air pressure build-up in tank. 6. After 15 minutes, move the On/Auto/Off lever to "OFF" position and close the drain valve (clockwise). 7. Move the On/Auto/Off lever to "ON/AUTO" position. The air receiver will fill to "cut-out" pressure and the motor will stop.
Customer Responsibilities Before each use Daily or after each use Check Safety Valve Pull the regulator knob out and turn clockwise to set the outlet pressure to zero. 3. Remove the air tool or accessory. 4. Pull ring on safety valve allowing air to bleed from the tank until tank pressure is approximately 20 psi. Release safety valve ring. 5. Drain water from air tank by opening drain valve (counter-clockwise) on bottom of tank. e Drain Tank To Check 2.
_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 pressure. ALL MAINTENANCE TRAINED SERVICE AND REPAIR TECHNICIAN. OPERATIONS Before servicing: • • • Unplug or disconnect electrical supply to the air compressor. Bleed tank of pressure. Allow the air compressor to cool.
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 3. Turn the regulator counterclockwise outlet pressure to zero, 4. Remove the air tool or accessory. 5. Pull ring on safety valve allowing air to bleed from the tank until tank pressure is approximately 20 psi. Release safety valve ring. 6.
Performing repairs may expose voltage sources, moving parts or compressed air sources, moving parts or compressd air sources. Personal injury may occur. Prior to attempting any repairs, unplug the air compressor and bleed off all air tank air pressure. PROBLEM Excessive tank pressure - safety valve pops off. CAUSE CORRECTION Pressure switch does not shut off motor when compressor reaches "cut-out" pressure.
CAUSE PROBLEM CORRECTION Knocking Noise. Defective check valve. Remove and clean, or replace. Compressor is not supplying enough air to operate accessories. Prolonged excessive use of air. Decrease amount of air usage. Compressor is not large enough for air requirement. Check the accessory air requirement. If it is higher than the SCFM or pressure supplied by your air compressor, you need a larger compressor. Hole in hose. Check and replace if required. Check valve restricted.
