OOPPEERRAATTIIOONN USING THE AIR COMPRESSOR See Figure 4, page 14. WARNING: Risk of bursting. Do not adjust pressure regulator knob to result in output pressure greater than marked maximum pressure of attachment and/or the item being inflated. Never use at pressure greater than 120 psi. Failure to heed this warning could result in possible serious personal injury. WARNING: Air powered tools may require more air consumption than this air compressor is capable of providing. Check the tool manual to avoid damage to the tool or risk of personal injury. n Ensure that the Auto On/Off switch is in the OFF position and the battery pack is not installed. n Attach air hose following the instructions in Connecting/ Disconnecting Air Hose (hose not provided). n Attach 1/4 in. NPT quick-connect air fitting to the accessory or tool you intend to use. n Insert the other end of the quick-connect air fitting to the quick coupler on the open end of hose. n Install the battery pack. n Move the Auto On/Off switch to the Auto On position. n Set the amount of air pressure desired using the pressure regulator knob. Pull the knob out, then turn clockwise to increase or counterclockwise to decrease the air pressure through the hose. When the desired pressure is set, push the knob back in to lock. NOTE: Always use the minimum amount of pressure necessary for your application. Using a higher pressure than needed will drain air from the tank more rapidly, cause the unit to cycle on more frequently, and reduce battery run time between charges. n Following all safety precautions in this manual and the manufacturer's instructions in the air tool manual, you may now proceed to use your air-powered tool. NOTE: The air compressor will shut off during an electrical overload. To reset the internal overload switch, turn off the air compressor and allow the unit to cool. Remove and then reinstall the battery packs before resuming operation. n When finished, always drain the tank, turn the unit off, and remove the battery packs. Never leave the unit on and/or running unattended. DRAINING THE TANK See Figures 5 - 6, page 14. To help prevent tank corrosion and keep moisture out of the air used, the air tank of the compressor should be drained daily. To drain: n Turn the air compressor off and remove the battery packs. n Pull the ring on the safety valve to release air until tank pressure gauge reads less than 20 psi. n Release the ring. n Turn the drain valves 90° counterclockwise to the ON (open) position. n Tilt tank to drain moisture from tank into a suitable container. NOTE: Condensate is a polluting material and should be disposed of in compliance with local regulations. n If a drain valve is clogged, release all air pressure, remove and clean valve, then reinstall. WARNING: Turn off the air compressor, remove battery packs, and release all air from the tank before servicing. Failure to depressurize tank before attempting to remove valve could cause serious personal injury. n Turn the drain valves 90° clockwise to the OFF (closed) position. WARNING: RISK OF BURSTING. All compressed air tanks have a limited lifespan. The lifespan can be affected by a number of factors, including operating conditions of the air compressor, proper maintenance of the tank, and unauthorized repairs and modifications. Since deterioration of the tank can occur internally with no outward signs, the air tank(s) on this compressor MUST be removed from service by the end of the year shown on the data label. Use of the air compressor after this date increases the risk of an air tank rupture, which could result in serious personal injury. 10 - English
