Place the air compressor on a flat surface so that resting securely on the rubber feet. LUBRICATION This air compressor is equipped with an Oil-Less pump designed for durability and no maintenance. Extension Cords To avoid voltage drop, power loss, and overheating of the motor, use extra air hose instead of an extension cord. Low voltage can cause damage to the motor. If an extension cord must be used: • Use only an approved 3-wire extension cord that has a 3- blade grounding plug and a 3- slot receptacle that will accept the plug on the air compressor. • Make sure the extension cord is in good condition. Please see the chart below for the MINIMUM extension cord gauge requirements: Amp Rating Range (120 V) 0 - 5 A 5 - 8 A 8 - 12 A 12 - 15 A 15 - 20 A 10 m 25 ft. 16 16 14 12 10 15 m 50 ft. 16 16 14 12 10 Total Length of Cord in Meter 20 m 75 ft. 30 m 100 ft. 16 14 14 12 12 10 10 10 10 50 m 150 ft. 12 10 60 m 200 ft. 12 Not Recommended 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. If a pipe line is necessary, use pipe that is the same size, or larger than, the air tank outlet. Piping that is too small will restrict the flow of air. If piping is over 100 feet long, use the next larger size. Bury underground lines below the frost line and avoid pockets where condensation can gather and freeze. Apply pressure before underground lines are covered to make sure all pipe joints are free of leaks. Grounding Instruction WARNING: Risk of electric shock! In the event of a short circuit, grounding reduces the risk of shock by providing an escape wire for the electric current. This air compressor must be properly grounded. The air compressor is equipped with a cord having a grounding wire with an appropriate grounding plug. The plug must be used with an outlet that has been installed and grounded in accordance with all local codes and ordinances. The outlet must have the same configuration as the plug. DO NOT USE AN ADAPTER. Inspect the plug and cord before each use. Do not use if there are signs of damage. DANGER: Improper grounding can result in electrical shock. Do not modify the plug that has been provided. If it does not fit the available outlet, the correct outlet should be installed by a qualified electrician. 6 OPERATING PROCEDURES Daily Start-up Checklist INSTALLING HOSES WARNING Risk of unsafe operation. Firmly grasp hose in hand when installing or disconnecting to prevent hose whip. Losing control of the hose may result in personal injury and property damage. 1. Before attaching air hose or accessories, make sure the pressure switch lever is set to "OFF" and the air regulator or shut-off valve is closed. 2. Attach hose and accessories. 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. 3. Turn the pressure switch lever to "ON/AUTO" and allow tank pressure to build. Motor will stop when tank pressure reaches "cut-out" pressure. 4. Open the regulator by turning it clockwise. Adjust the regulator to the correct pressure setting. Your compressor is ready for use. 5. Always operate the air compressor in well-ventilated areas; free of gasoline or other solvent vapors. Do not operate the compressor near the spray area. When you are finished: DISCONNECTING HOSES WARNING Risk of unsafe operation. Firmly grasp hose in hand when installing or disconnecting to prevent hose whip. Losing control of the hose may result in personal injury and property damage. 6. Set the pressure switch lever to "OFF". 7. Using the air tool or accessory, bleed the tank pressure down to zero. 8. Remove the air tool or accessory.
