MCN150 / MCN250 / MCN250S TOOL SPECIFICATIONS
All screws and nuts are metric.
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”.
TOOL AIR FITTING:
This tool uses a 1/4” N.P.T. male plug. The inside diameter should be .200” (5mm) or larger. The fitting must
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
2
). Take the actual rate at which the tool will be run to determine the
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
2
). Take the actual rate at which the tool will be run to
deteremine the amount of air required. For instance, if you fastener usuage averages 50 nails per minute, you
need 50% of the 7.7 c.f.m. (218 liters per minute) which is required to operate the tool at 100 nails per minute.
