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. What Could Happen How To Prevent It Drain tank daily or after each use. If tank develops a leak, replace it immediately with a new tank or replace the entire compressor. 1. Failure to properly drain condensed water from tank, causing rust and thinning of the steel tank. 2.
HAZARD WARNING: 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. 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 CAN HAPPEN HOW TO PREVENT IT Touching exposed metal such as the compressor head or outlet tubes, can result in serious burns. 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.
HAZARD WARNING: RISK OF SERIOUS INJURY OR PROPERTY DAMAGE WHEN TRANSPORTING COMPRESSOR (Fire, Inhalation, Damage to Vehicle Surfaces) WHAT CAN 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.
ON-RECEIPT INSPECTION Each air compressor outfit is carefully checked before shipment. With improper handling, damage may result in transit and cause problems in air compressor operation. Immediately upon arrival, check equipment for both concealed and visible damages to avoid expenses being incurred to correct such problems. This should be done regardless of any visible signs of damage to the shipping container. Report any damages to carrier and arrange for inspection of goods immediately.
ASSEMBLY (does not apply to all units) Some models require no assembly. If your unit requires assembly, match the instructions below to your unit. Assembly for “Pancake” units 1. Carefully place unit on side opposite of controls. 2. Using a 3/8 inch socket or nut driver remove the screws attaching the unit to the shipping pallet. Leg NOTE: These screws will be used to install the rubber feet. 3. Attach the four rubber feet to the unit’s legs using the four screws removed in step 2.
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 Using extension cords is not recommended. The use of extension cords will cause voltage to drop resulting in power loss to the motor and overheating. Instead of using an extension cord, increase the working reach of the air hose by attaching another length of hose to its end. Attach additional lengths of hose as needed.
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.
Pressure Release Valve: The pressure release Pressure Release valve located on the side of the pressure switch, is Valve designed to automatically release compressed air from the compressor head and the outlet tube when the air compressor reaches “cut-out” pressure or is shut off. The pressure release valve allows the motor to restart freely. When the motor stops running, air will be heard escaping from this valve for a few seconds.
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. How to Start: 1. Turn the On/Auto/Off lever to “AUTO” and allow tank pressure to build. Motor will stop when tank pressure reaches “cut-out” pressure. 2. Pull the regulator knob out and turn clockwise to increase pressure. When the desired pressure is reached push knob in to lock in place.
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. Before performing any Maintenance or repair, unplug the compressor and bleed off all air pressure. ALL MAINTENANCE AND REPAIR OPERATIONS NOT LISTED MUST BE PERFORMED BY TRAINED SERVICE TECHNICIAN. ● ● ● Before servicing: Unplug or disconnect electrical supply to the air compressor. Bleed tank of pressure.
To Replace Regulator 1. Release all air pressure from air tank. See “To Drain Tank” in the Maintenance section. 2. Unplug outfit. 3. Using an adjustable wrench remove the gauges and quick connect or hose adapter from the regulator. 4. Remove the regulator. 5. Apply pipe sealant tape to the nipple on the standpipe or regulator. 6. Assemble the regulator and orient as shown. NOTE: Arrow indicates flow of air. Make sure it is pointing in the direction of air flow. 7.
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 not Excessive tank pressure - safety shut off motor when compressor reaches “cut-out” valve pops off. pressure.
PROBLEM CAUSE Pressure reading It is normal for “some” preson the regulated sure drop to occur. pressure gauge drops when an accessory is used. CORRECTION 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). Prolonged excessive use of air. Decrease amount of air usage.
PROBLEM Motor will not run. CAUSE Fuse blown, circuit breaker tripped. CORRECTION Check fuse box for blown fuse and replace as necessary. Reset circuit breaker. Do not use a fuse or circuit breaker with higher rating than that specified for your particular branch circuit. Check for proper fuse. You should use a time delay fuse. Check for low voltage problem. Check the extension cord. Disconnect the other electrical appliances from circuit or operate the compressor on its own branch circuit.
