OOPPEERRAATTIIOONN CHECKING THE SAFETY VALVE See Figure 5, page 14. DANGER: Do not attempt to tamper with the safety valve. Anything loosened from this device could fly up and hit you. Failure to heed this warning could result in death or serious personal injury. The safety valve will automatically release air if the air tank pressure exceeds the cut-out pressure. The valve should be checked before each day of use by pulling the ring by hand. n Install the battery pack. n Turn the air compressor on and allow the tank to fill. The compressor will shut off when the pressure reaches the cut-out pressure. n Turn the air compressor off. n Pull the ring on the safety valve to release air for three to five seconds to allow pressurized air to escape. Release the ring. The safety release valve must reset and hold pressure before all compressed air is exhausted from the tank/pressure vessel. n Any continued loss of air after performing the above steps indicates a problem with the safety valve. Discontinue use and seek service before continued use of the air compressor. WARNING: If air leaks after the ring has been released or if the valve is stuck and cannot be actuated by the ring, do not use the air compressor until the safety valve has been replaced. Use of the air compressor in this condition could result in serious personal injury.
