N88 TOOL SPECIFICATIONS
All screws and nuts are metric.
FASTENER SPECIFICATIONS:
N88WWB
This tool uses a 28° wire collated stick nail in lengths of 2” to 3-1/2” (50 - 90mm) and shank diameters of .113” to .131” (2.8 - 3.3mm)
N88RH
Uses a 21° plastic collated full round head stick nails, in lengths of 2” to 3-1/2” (50-90mm) and shank diameters of .113” to .162” (2.8 - 4.1mm).
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 120 p.s.i.g. (4.9 to 8.4 kg/cm
2
). Select the operating pressure within this range for best fastener performance.
DO NOT
EXCEED THIS RECOMMENDED OPERATING PRESSURE.
AIR CONSUMPTION:
The N88 requires 7.5 cubic feet per minute (212 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 7.5 c.f.m. (212 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.
