N79WW-2/N80SB-2
Sequential Trip
FASTENER SPECIFICATIONS:
This tool uses a wide range of nail sizes in lengths of 2" to 3-1/2" (50 - 90mm) and shank diameters of .113" to
.131" (2.8 - 3.3mm)
TOOL AIR FITTING:
This tool uses a 1/4" N.P.T. male plug. The inside diameter should be .275" (7mm) or larger. The fitting must
be capable of discharging tool air pressure when disconnected from the air supply.
OPERATING PRESSURE:
70 to 100 p.s.i.g. (4.9 to 7.0 kg/cm2). Select the operating pressure within this range for best fastener
performance. DO NOT EXCEED THIS RECOMMENDED OPERATING PRESSURE.
AIR CONSUMPTION:
The N79WW/N80SB requires 7.8 cubic feet per minute (221 liters per minute) of free air to operate at the rate
of 100 nails per minute, at 80 p.s.i. (5.6 kg/cm2). 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 7.8 c.f.m. (221 liters per minute) 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.
