t
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 is used.
Additional Safety Protection will be required in some environments. For example,
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. A contact 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.
This nailer produces SPARKS during operation. NEVER use the nailer near flammable
substances, gases or vapors including lacquer, paint, benzine, thinner, gasoline, adhesives,
mastics, glues or any other material that is -- or the vapors,fumes or byproducts of which are -flammable, combustible or explosive. Using the nailer in any such environment could cause an
EXPLOSION resulting in personal injury or death to user and bystanders.

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 N80CB requires 7.8 cubic feet per minute of free air to operate at the rate of 100 nails per minute, at 80
p.s.i.g. (5.6 kg/cm
For instance, if your fastener usage averages 50 nails per minute, you need 50% of the 7.8 c.f.m. which is
required for running at 100 nails per minute.
2
). Take the actual rate at which the tool will be run to determine the amount of air required.
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.

GASES, OR BOTTLED GASES, AS A POWER SOURCE FOR THIS TOOL AS TOOL MAY EXPLODE.
REGULATOR:
A pressure regulator with an operating pressure of 0 - 125 p.s.i. (0 - 8.79 kg/cm2) is required to control the
operat iing pressure for safe operation of this tool. Do not connect this tool to air pressure which can potentially
exceed 200 p.s.i. (14 kg/cm
2
) as tool may fracture or burst, possibly causing injury.
OPERATING PRESSURE:
Do not exceed recommended maximum operating pressure as tool wear will be greatly increased. The air
supply must be capable of maintaining the operating pressure at the tool. Pressure drops in the air supply can
reduce the tool’s driving power. Refer to “TOOL SPECIFICATIONS” for setting the correct operating pressure
for the tool.
FILTER:
Dirt and water in the air supply are major causes of wear in pneumatic tools. A filter will help to get the best
performance and minimum wear from the tool. The filter must have adequate flow capacity for the specific
installation. The filter has to be kept clean to be effective in providing clean compressed air to the tool. Consult
the manufacturer’s instructions on proper maintenance of your filter. A dirty and clogged filter will cause a
pressure drop which will reduce the tool’s performance.

LUBRICATION
Frequent, but not excessive, lubrication is required for best performance. Oil added through the air line
connection will lubricate the internal parts. Use BOSTITCH Air Tool Lubricant, Mobil Velocite #10, or equivalent.
Do not use detergent oil or additives as these lubricants will cause accelerated wear to the seals and bumpers
in the tool, resulting in poor tool performance and frequent tool maintenance.
If no airline lubricator is used, add oil during use into the air fitting on the tool once or twice a day. Only a few
drops of oil at a time is necessary. Too much oil will only collect inside the tool and will be noticeable in the
exhaust cycle.
COLD WEATHER OPERATION:
For cold weather operation, near and below freezing, the moisture in the air line may freeze and prevent tool
operation. We recommend the use of BOSTITCH WINTER FORMULA air tool lubricant or permanent
antifreeze (ethylene glycol) as a cold weather lubricant.
CAUTION: Do not store tools in a cold weather environment to prevent frost or ice formation on the
tools operating valves and mechanisms that could cause tool failure.
NOTE:Some commercial air line drying liquids are harmful to “O”-rings and seals – do not use these
low temperature air dryers without checking compatibility.

BEFORE HANDLING OR OPERATING THIS TOOL:
I. READ AND UNDERSTAND THE WARNINGS CONTAINED IN THIS MANUAL.
II. REFER TO “TOOL SPECIFICATIONS” IN THIS MANUAL TO IDENTIFY THE
PERATING SYSTEM ON YOUR TOOL.
O
here are two available systems on BOSTITCH pneumatic tools. They are:
T
1. CONTACT TRIP OPERATION 2. SEQUENTIAL TRIP OPERATION
OPERATION
1. CONTACT TRIP OPERATION:
The CONTACT TRIP MODEL tool contains a contact trip that operates in conjunction with the trigger to
drive a fastener. There are two methods of operation to drive fasteners with a contact trip tool.
A. SINGLE FASTENER PLACEMENT: To operate the tool in this manner, first position the contact trip
on the work surface, WITHOUT PULLING THE TRIGGER. Depress the contact trip until the nose
touches the work surface and then pull the trigger to drive a fastener. Do not press the tool against
the work with extra force. Instead, allow the tool to recoil off the work surface to avoid a second
unwanted fastener. Remove your finger from the trigger after each operation.
B. RAPID FASTENER OPERATION: To operate the tool in this manner, hold the tool with the contact
trip pointing towards but not touching the work surface. Pull the trigger and then tap the contact trip
against the work surface using a bouncing motion. Each depression of the contact trip will cause a
fastener to be driven.
The operator must not hold the trigger pulled on contact trip 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. A contact trip tool may
bounce from the recoil of driving a fastener and an unwanted second fastener may be
driven, possibly causing injury.
2. SEQUENTIAL TRIP OPERATION:
The SEQUENTIAL TRIP MODEL contains a contact trip that operates in conjunction with the trigger to
drive a fastener. To operate a sequential trip tool, first position the contact trip on the work surface
WITHOUT PULLING THE TRIGGER. Depress the contact trip and then pull the trigger to drive a
fastener. As long as the contact trip is contacting the work and is held depressed, the tool will drive a
fastener each time the trigger is depressed. If the contact trip is allowed to leave the work surface, the
sequence described above must be repeated to drive another fastener.

MAINTAINING THE PNEUMATIC TOOL
When working on air tools, note the warnings in this manual and use extra care evaluating
problem tools.
REPLACEMENT PARTS:
OSTITCH replacement parts are recommended. Do not use modified parts or parts which will not give
B
equivalent performance to the original equipment.
ASSEMBLY PROCEDURE FOR SEALS:
When repairing a tool, make sure the internal parts are clean and lubricated. Use Parker “O”-LUBE or
quivalent on all “O”-rings. Coat each “O”-ring with “O”-LUBE before assembling. Use a small amount of oil on
e
all moving surfaces and pivots. After reassembly add a few drops of BOSTITCH Air Tool Lubricant through the
ir line fitting before testing.
a
AIR SUPPLY-PRESSURE AND VOLUME:
ir volume is as important as air pressure. The air volume supplied to the tool may be inadequate because of
A
undersize fittings and hoses, or from the effects of dirt and water in the system. Restricted air flow will prevent
the tool from receiving an adequate volume of air, even though the pressure reading is high. The results will be
slow operation, misfeeds or reduced driving power. Before evaluating tool problems for these symptoms, trace
the air supply from the tool to the supply source for restrictive connectors, swivel fittings, low points containing
water and anything else that would prevent full volume flow of air to the tool.
