FASTENER SPECIFICATIONS:
MCN150: Uses a 35° paper collated full round head metal connector nails, in lengths of 1-1/2" (38mm) and
shank diameters of .131", .148".
MCN250 & MCN250S: Uses a 35° paper collated full round head metal connector nails, in lengths of 1-1/2"
and 2-1/2" (38 - 64mm) and shank diameters of .131", .148", .162".

be capable of discharging tool air pressure when disconnected from the air supply.
OPERATING PRESSURE:
70 to 120 p.s.i.g. (4.9 to 8.4 kg/cm2 ). Select the operating pressure within this range for best fastener
performance. DO NOT EXCEED THIS RECOMMENDED OPERATING PRESSURE.
AIR CONSUMPTION:
The MCN150 requires 6.7 cubic feet per minute (190 liters per minute) of free air to operate at the rate of 100
nails per minute, at 80 p.s.i. (5.6 kg/cm
amount of air required. For instance, if your fastener usage averages 50 nails per minute, you need 50% of the
6.7 c.f.m. (190 liters per minute) which is required to operate the tool at 100 nails per minute.
The MCN250 & MCN250S requires 7.7 cubic feet per minute (218 liters per minute) of free air to operate at the
rate of 100 nails per minute, at 80 p.s.i. (5.6 kg/cm
