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.
Alwaysdisconnect air supply: 1.) Before making adjustments; 2.)When servicingthe
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.
MAINTAINING THE TOOL
When working on air tools note the warnings in this manual and use extra care
when evaluating problem tools.

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 N70CB requires 7.7 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/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 7.7
c.f.m. which is required for running 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.

SUPPLY SOURCE:
Use only clean regulated compressed air as a power source for this tool. NEVER USE OXYGEN,
COMBUSTIBLE 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 operatiing 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/CM2)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:
tools operating valves and mechanisms that could cause tool failure.
NOTE:
low temperature air dryers without checking compatibility.
Do not store tools in a cold weather environment to prevent frost or ice formation on the
Some commercial air line drying liquids are harmful to “O”-rings and seals – do not use these

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
OPERATING SYSTEM ON YOUR TOOL.
here are three available systems on BOSTITCH pneumatic tools. They are:
T
1. TRIGGER OPERATION 2. CONTACTTRIP OPERATION 3. SEQUENTIAL TRIP OPERATION
OPERATION
1. TRIGGER OPERATION
A TRIGGER OPERATED tool requires a single action to drive a fastener. Each time the trigger is
pulled the tool will drive a fastener. The trigger operated model is intended for use only when a
contact trip or sequential trip cannot be used due to the requirements of the application.
2. 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.
3. 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.
-7-
TOOL OPERATION CHECK:
AUTION:Remove all fasteners from tool before performing tool operation check.

MAINTAINING THE PNEUMATIC TOOL
hen working on air tools, note the warnings in this manual and use extra care
W
evaluating problem tools.
CAUTION: Pusher spring (constant force spring). Caution must be used when working with the
pring assembly.The spring is wrapped around, but not attached to, a roller. If the spring is
s
extended beyond its length, the end will come off the roller and the spring will roll up with a
snap, with a chance of pinching your hand. Also the edges of the spring are very thin and could
ut. Care must also be taken to insure no permanent kinks are put in the spring as this will
c
reduce the springs force.
REPLACEMENT PARTS:
BOSTITCH replacement parts are recommended. Do not use modified parts or parts which will not
ive equivalent performance to the original equipment.
g
ASSEMBLY PROCEDURE FOR SEALS:
When repairing a tool, make sure the internal parts are clean and lubricated. Use Parker “O”-LUBE or
equivalent on all “O”-rings. Coat each “O”-ring with “O”-LUBE before assembling. Use a small amount of
oil on all moving surfaces and pivots. After reassembly add a few drops of BOSTITCH Air Tool Lubricant
through the air line fitting before testing.
AIR SUPPLY-PRESSURE AND VOLUME:
Air volume is as important as air pressure. The air volume supplied to the tool may be inadequate
because of 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.
