N75C TOOL SPECIFICATIONS
All screws and nuts are metric.
FASTENER SPECIFICATIONS:
This tool will accept plastic and wire collated coil nails in lengths of 1-1/2” to 3” (38 - 75mm) and shank
diameters of .090” to .131” (2.3mm to 3.3mm).
TOOL AIR FITTING:
This tool uses a free-flow connector plug, 1/4” N.P.T. The minimum inside diameter should be .200” (5mm). 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. (4.8 to 8.3 kg/cm
2
). Select the operating pressure within this range for best fastener
performance.
DO NOT EXCEED THE RECOMMENDED OPERATING PRESSURE.
AIR CONSUMPTION:
The N75C requires 5.40 cubic feet per minute (.153 m
3
) of free air to operate at the rate of 100 nails per minute, at
80 p.s.i. (5.62 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 tool’s c.f.m. which is required to
operate the tool at 100 nails per minute.
OPERATION
BOSTITCH OFFERS TWO TYPES OF OPERATION FOR THIS SERIES TOOL.
CONTACT TRIP:
The common operating procedure on “Contact Trip” tools is for the operator to contact the work to actuate the
trip mechanism while keeping the trigger pulled, thus driving a fastener each time the work is contacted. This
will allow rapid fastener placement on many jobs, such as sheathing, decking and pallet assembly. All
pneumatic tools are subject to recoil when driving fasteners. The tool may bounce, releasing the trip, and if
unintentionally allowed to recontact the work surface with the trigger still actuated (finger still holding trigger
pulled) an unwanted second fastener will be driven.
SEQUENTIAL TRIP:
The Sequential Trip requires the operator to hold the tool against the work before pulling the trigger. This
makes accurate fastener placement easier, for instance on framing, toe nailing and crating applications.The
Sequential Trip allows exact fastener location without the possibility of driving a second fastener on recoil, as
described under “Contact Trip”. The Sequential Trip Tool has a positive safety advantage because it will not
accidentally drive a fastener if the tool is contacted against the work – or anything else – while the operator is
holding the trigger pulled.
