SAFETY GUIDELINES - DEFINITIONS This manual contains information that is important for you to know and understand. This information relates to protecting YOUR SAFETY and PREVENTING EQUIPMENT PROBLEMS. To help you recognize this information, we use the symbols below. Please read the manual and pay attention to these symbols. Indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury.
IMPORTANT SAFETY INSTRUCTIONS Save these instructions Improper operation or maintenance of this product could result in serious injury and property damage. Read and understand all warnings and operation instructions before using this equipment. HAZARD WARNING: Risk of explosion or fire What Could Happen How To Prevent It It is normal for electrical contacts within the motor and pressure switch to spark.
HAZARD WARNING: 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. How To Prevent It What Could Happen Failure to properly drain condensed water from tank, causing rust and thinning of the steel tank. Drain tank daily or after each use. If tank develops a leak, replace it immediately with a new tank or replace the entire compressor.
HAZARD WARNING: Risk of Electrical Shock What Could 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. Never operate compressor with protective covers removed or damaged. Repairs attempted by unqualified personnel can result in serious injury or death by electrocution.
HAZARD WARNING: Risk of Burns What Could Happen How To Prevent It Never touch any exposed metal parts on compressor during or immediately after operation. Compressor will remain hot for several minutes after operation. Do not reach around protective shrouds or attempt maintenance until unit has been allowed to cool. Touching exposed metal such as the compressor head or outlet tubes, can result in serious burns.
HAZARD WARNING: Risk of Serious Injury or Property Damage When Transporting Compressor (Fire, Inhalation, Damage to Vehicle Surfaces) What Could Happen How To Prevent It Oil can leak or spill and could result in fire or breathing hazard; serious injury or death can result. oil leaks will damage carpet, paint or other surfaces in vehicles or trailers. Always place COMPRESSOR on a protective mat when transporting to protect against damage to vehicle from leaks.
GLOSSARY Become familiar with these terms before operating the unit. CFM: 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. Code Certification: Products that bear one or more of the following marks: UL, CUL, ETL, CETL, have been evaluated by OSHA certified independent safety laboratories and meet the applicable Underwriters Laboratories Standards for Safety.
ASSEMBLY Tools Required for Assembly 1 - 9/16" socket or open end wrench 1 - 1/2" socket or open end wrench Unpacking 1. Remove all packaging leaving the air compressor on the pallet. 2. Remove and discard the (4) screws holding the air compressor to the pallet. It may be necessary to brace or support one side of the air compressor when removing the pallet because the air compressor will have a tendency to tip. 3. Carefully remove the air compressor from the pallet.
INSTALLATION 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 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.
Check Valve: When the air compressor is operating, the check valve is "open", allowing compressed air to enter the air tank. When the air Check Valve compressor reaches "cut-out" pressure, the check valve "closes", allowing air pressure to remain inside the air tank.
Before Each Start-Up: 1. Place On/Auto/Off lever to "OFF". 2. Turn the regulator knob counterclockwise to set the outlet pressure to zero. 3. Attach hose and accessories. NOTE: The hose or accessory will require a quick connect plug if the air outlet is equipped with a quick connect. 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.
To ensure efficient operation and longer life of the air compressor outfit, a routine maintenance schedule should be prepared and followed. The following routine maintenance schedule is geared to an outfit in a normal working environment operating on a daily basis. If necessary, the schedule should be modified to suit the conditions under which your compressor is used. The modifications will depend upon the hours of operation and the working environment.
If it is dirty, replace it with a new filter. On some models,the filter may be removed by using a pair of needle nose pliers or a screwdriver. Pull or pry out the old filter and carefully clean the filter area. Push in the new air filter. Air Compressor Pump Intake and Exhaust Valves Once a year have a Trained Service Technician check the air compressor pump intake and exhaust valves. SERVICE AND ADJUSTMENTS Unit cycles automatically when power is on.
8. Apply sealant to the check valve threads. Reinstall the check valve (turn clockwise). 9. Replace the pressure release tube. Tighten nuts. 10. Replace the outlet tube and tighten nuts. 11. Perform the Break-in Procedure. See "Break-in Procedure" in the Operation section. To Replace Regulator 1. 2. 3. 4. 5. Release all air pressure from air tank. See "To Drain Tank" in the Maintenance section. Unplug compressor. Remove the outlet pressure gauge and quick connect (if equipped) from the regulator.
STORAGE 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 lever to "OFF". 3. Turn the regulator counterclockwise and set the 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.
TROUBLESHOOTING Performing repairs may expose voltage sources, moving parts or compressed air sources, moving parts or compressed air sources. Personal injury may occur. Prior to attempting any repairs, unplug the air compressor and bleed off all air tank air pressure. PROBLEM CAUSE Pressure switch does Excessive tank pressure - safety not shut off motor when compressor reaches "cutvalve pops off. out" pressure.
PROBLEM CAUSE Pressure reading It is normal for "some" on the regulated pressure drop to occur. pressure gauge drops when an accessory is used. Knocking Noise. Possible defect in safety valve. Defective check valve. Compressor is not supplying enough air to operate accessories. Regulator knob has continuous air leak.
PROBLEM Regulator will not shut off air outlet. Motor will not run. CAUSE Damaged regulator CORRECTION Replace Motor overload protection switch has tripped Let motor cool off and overload switch will automatically reset. Motor will start automatically when tank pressure drops below "cut-in" pressure of pressure switch. Check for proper gauge wire and cord length. Tank pressure exceeds pressure switch "cut-in" pressure. Extension cord is wrong length or gauge. Check valve stuck open.
