SAFETY INSTRUCTIONS
EYE PROTECTION which conforms to ANSI specifications and provides protection
against flying particles both from the FRONT and SIDE should ALWAYS be worn
by the operator and others in the work area when loading, operating or servicing
this tool. Eye protection is required to guard against flying fasteners and debris,
which could cause severe eye injury.
The employer and/or user must ensure that proper eye protection is worn. Eye
protection equipment must conform to the requirements of the American National
Standards Institute, ANSI Z87.1-1989 and provide both frontal and side protection.
NOTE: Non-side shielded spectacles and face shields alone do not provide adequate protection.
CAUTION:
ADDITIONAL SAFETY PROTECTION will be required in some environments. For example, the working area may include exposure to noise level which
can lead to hearing damage. The employer and user must ensure that any necessary
hearing protection is provided and used by the operator and others in the work area.
Some environments will require the use of head protection equipment. When
required, the employer and user must ensure that head protection conforming to
ANSI Z89.1 1986 is used.
AIR SUPPLY AND CONNECTIONS
Do not use oxygen, combustible gases, or bottled gases as a power source for this
tool as tool may explode, possibly causing injury.
Do not use supply sources which can potentially exceed 200 P.S.I.G. as tool may
burst, possibly causing injury.
The connector on the tool must not hold pressure when air supply is disconnected. If a wrong fitting is used, the tool can remain charged with air after disconnecting and thus will be able to drive a fastener even after the air line is disconnected possibly causing injury.
Do not pull trigger or depress contact arm while connected to the air supply as the
tool may cycle, possibly causing injury.
Always disconnect air supply: 1.) Before making adjustments; 2.) When servicing
the tool; 3.) When clearing a jam; 4.) When tool is not in use; 5.) When moving to a
different work area, as accidental actuation may occur, possibly causing injury.
LOADING TOOL
When loading tool: 1.) Never place a hand or any part of body in fastener discharge area of tool; 2.) Never point tool at anyone; 3.) Do not pull the trigger or
depress the trip as accidental actuation may occur, possibly causing injury.
OPERATION
Always handle the tool with care: 1.) Never engage in horseplay; 2.) Never pull
the trigger unless nose is directed toward the work; 3.) Keep others a safe distance from the tool while tool is in operation as accidental actuation may occur,
possibly causing injury.
The operator must not hold the trigger pulled on contact arm tools except during fastening operation as serious injury could result if the trip accidentally contacted someone or something, causing the tool to cycle.
Keep hands and body away from the discharge area of the tool. Acontact arm tool
may bounce from the recoil of driving a fastener and an unwanted second fastener may be driven possibly causing injury.
Check operation of the contact arm mechanism frequently. Do not use the tool if
the arm is not working correctly as accidental driving of a fastener may result. Do
not interfere with the proper operation of the contact arm mechanism.
Do not drive fasteners on top of other fasteners or with the tool at an overly steep
angle as this may cause deflection of fasteners which could cause injury.
Do not drive fasteners close to the edge of the work piece as the wood may split,
allowing the fastener to be deflected possibly causing injury.
MAINTAINING THE TOOL
When working on air tools note the warnings in this manual and use extra care
when evaluating problem tools.

N79WW/N80SB TOOL SPECIFICATIONS
All screws and nuts are metric.
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/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 7.8 c.f.m. (221 liters
per minute) which is required to operate the tool at 100 nails per minute.
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.
