LIMITED WARRANTY ONE YEAR FROM DATE OF PURCHASE All merchandise manufactured by DeVilbiss Air Power Company/ExCell Manufacturing is warranted to be free of defects in workmanship and material which occur during the first year from the date of purchase by the original purchaser (initial user). Products covered under this warranty include: air compressors, *air tools, accessories, service parts, pressure washers, and generators used in consumer applications (i.e., personal residential household usage only).

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 OPERATING INSTRUCTIONS BEFORE USING THIS EQUIPMENT. HAZARD RISK OF BURSTING WHAT CAN HAPPEN HOW TO PREVENT IT AIR TANK THE FOLLOWING CONDITIONS COULD LEAD TO A WEAKENING OF THE TANK, AND RESULT IN A VIOLENT TANK EXPLOSION: 1.
PAGE 4
HAZARD WHAT CAN HAPPEN HOW TO PREVENT IT RISK OF ELECTRICAL SHOCK 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. REPAIRS ATTEMPTED BY UNQUALIFIED PERSONNEL CAN RESULT IN SERIOUS INJURY OR DEATH BY ELECTROCUTION.
PAGE 5
SPECIFICATIONS Refer to Outfit Part Listing for the specifications of your compressor. Use only a fuse or circuit breaker that is the same rating as the branch circuit the air compressor is operated on. If the compressor is connected to a circuit protected by fuses, use dual element time delay fuses, as noted in the Outfit Parts Listing. Improper electrical installation of this product may void its warranty and your fire insurance.
PAGE 6
DESCRIPTION OF OPERATION Drain Valve: The drain valve is located at the base of the air tank and is used to drain condensation at the end of each use. Pressure Release Valve: The pressure release valve located on the side of the pressure switch, is 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. If the air is not released, the motor will try to start, but will be unable to.
PAGE 7
Voltage and Circuit Protection Lubrication and Oil Refer to your Outfit Parts Manual for the voltage and circuit protection requirements of your compressor. Use only a fuse or circuit breaker that is the same rating as the branch circuit the air compressor is operated on. If the compressor is connected to a circuit protected by fuses, use only dual element time delay fuses, as noted in that Outfit Parts Manual. Multi-Viscosity motor oils, like 10W 30, should not be used in an air compressor.
PAGE 8
INSTALLATION AND BREAK-IN PROCEDURES (cont'd) Wiring of Compressor Units Piping Plastic or PVC pipe is not designed for use with compressed air. Regardless of its indicated pressure rating, plastic pipe can burst from air pressure. Use only metal pipe for air distribution lines. The main distribution air line should not be smaller than the compressor air discharge valve outlet. A smaller line will restrict the flow of air.
PAGE 9
INSTALLATION AND BREAK-IN PROCEDURES (cont'd) Typical Compressed Air Distribution System OPERATING PROCEDURES Daily Start-Up Checklist Perform the following checks before starting the compressor outfit. 1. Make sure that nothing is blocking the belt guard air openings or air filter opening. 2. Pull the ring on all safety valves to make sure the valves move freely and smoothly. 3. Check the oil level; add oil if necessary. 4. Clean or blow off fins or any part of compressor that collects dust and dirt.
PAGE 10
OPERATING PROCEDURES (cont'd) 5. When You Are Finished: drain tank pressure at approximately 20 PSI, open the drain valve and allow moisture to drain. Normal Operation (cont'd) 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.
PAGE 11
SERVICE INSTRUCTIONS Safety Valve - Inspection and Replacement Air Filter - Inspection and Replacement IF THE SAFETY VALVE DOES NOT WORK PROPERLY, OVER-PRESSURIZATION MAY OCCUR CAUSING AIR TANK RUPTURE OR EXPLOSION. DAILY PULL THE RING ON THE SAFETY VALVE TO MAKE SURE THAT THE SAFETY VALVE OPERATES FREELY. IF THE VALVE IS STUCK OR DOES NOT OPERATE SMOOTHLY, IT MUST BE REPLACED WITH A VALVE HAVING THE SAME PRESSURE RATING. Keep the air filter clean at all times.
PAGE 12
SERVICE INSTRUCTIONS (cont'd) within 1/32”. To check alignment, remove and lock out power from the compressor. Remove beltguard. Place a straight edge (such as a ruler) against the outside of the flywheel and measure the distance from it to the nearest groove. Alignment is achieved when the other end of the straight edge is within 1/32” of the measured dimension at the pulley grooves. If the pulleys are not aligned, loosen the motor pulley set screw. Slide pulley until alignment is achieved.
PAGE 13
TROUBLESHOOTING GUIDE PERFORMING REPAIRS MAY EXPOSE VOLTAGE SOURCES, MOVING PARTS OR COMPRESSED AIR SOURCES. PERSONAL INJURY MAY OCCUR. PRIOR TO ATTEMPTING ANY REPAIRS, UNPLUG THE COMPRESSOR AND BLEED OFF ALL TANK AIR PRESSURE. PROBLEM CAUSE CORRECTION Excessive tank pressure - safety valve pops off. Pressure switch does not shut off motor when compressor reaches “cut-out” pressure. Move the pressure switch lever to the “OFF” position.
PAGE 14
PROBLEM CAUSE CORRECTION Motor will not run. Motor overload protection switch has tripped. Let the motor cool off and reset switch by pressing the red button located on the end of the motor. If the overload still trips, check for defective capacitor. Possible defective starting capacitor. Contact Authorized Warranty Service Center for inspection or replacement if necessary. Possible defective motor. Have checked by a local Authorized Warranty Service Center.
PAGE 15
PROBLEM CAUSE CORRECTION Excessive belt wear. Loose belt. Adjust tension per instructions. (See "Belt Adjustment or Replacement" page 12) Adjust tension. (See "Belt Adjustment" section on page 12.) Tight belt. Check for worn keyway or pulley bore. Also check for bent motor shaft. Replace parts if necessary. Loose pulley. Pulley misalignment. Motor pulley and flywheel must be in line within 1/32". (See "Pulley and Flywheel Alignment" section on page 12.) Loose belt. Adjust belt tension.
