Operating Pressure:

70to 120 p.s.i.g. (4.9 to 8.43 kg/cm2). Select the operating pressure within in this range for best fastener
performance.

Air Consumption:

TheBT1855 and SX1838 require 2.83 cubic feet per minute or C.F.M. (80.1 liters per minute or LT/MIN)
offree air at 80PSI (5.6 kg/cm2) to operate at a rate of 60 fasteners per minute. To determine the
appropriatelysized air compressor, take the actual rate at which the tool will be run and compare the
requiredC.F.M. (LT/MIN) to the compressors free air delivery (C.F.M./LT/MIN) at 80 PSI (5.6 kg/cm2).
Forexample, if your fastener usage averages 30 fasteners per minute, you need 50% of the tools C.F.M.
requiredto operate the tool at the rate of 60 fasteners per minute. In this case, be sure that your air
compressorcan deliver a minimum of 1.42 C.F.M. (40.2 LT/MIN) at 80 PSI(5.6 kg/cm2) for optimum
performance.
