ToolAir Fitting:

Thistool uses a free-flow connector plug, 1/4”N.P.T.The minimum inside diameter shouldbe .200” (5mm).
Thefitting must be capable of discharging tool air pressurewhen disconnected from the air supply.

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.DO NOT EXCEED THIS RECOMMENDEDOPERATING PRESSURE.

Air Consumption:

The651 Series staplers require 5.3 cubic feet per minute or C.F.M.(150 liters per minute or LT/MIN) of free
airat 80PSI (5.6 kg/cm2) to operate at a rate of 100 fasteners per minute. Todetermine the appropriately
sizedair compressor, take the actual rate at which the tool will be run and compare the required C.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 50 fasteners per minute, youneed 50% of the tools C.F.M.
requiredto operate the tool at the rate of 100 fasteners per minute. In this case, be sure that your air
compressorcan deliver a minimum of 2.7 C.F.M.(75 LT/MIN)at 80 PSI(5.6 kg/cm2) for optimum performance.
