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 connecting to air supply, 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/CAN/CSA Z94.3 and provide both frontal and side protection. NOTE:
Non-side shielded spectacles and face shields alone do not provide adequate protection.

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 CAN/CSA Z89.1 is used.

Some dust created by power sanding, sawing, grinding, drilling, and other construction
activities contains chemicals known to the State of California to cause cancer, birth
defects or other reproductive harm. Some examples of these chemicals are:

• lead from lead-based paints

• crystalline silica from bricks and cement and other masonry products

• arsenic and chromium from chemically-treated lumber

Your risk from these exposures varies, depending on how often you do this type of work.
To reduce your exposure to these chemicals: work in a well ventilated area, and work with
approved safety equipment, such as those dust masks that are specially designed to filter
out microscopic particles.

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.

Use only clean, dry, regulated air. Condensation from an air compressor can rust and

damage the internal workings of the tool.
Do not use supply sources which can potentially exceed 200 p.s.i.g. (14 kg/cm2) 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.

Connect tool to air supply before loading fasteners, to prevent a fastener from being fired
during connection. The tool driving mechanism may cycle when tool is connected to the
air supply. Do not load fasteners with trigger or contact trip depressed, to prevent
unintentional firing of a fastener.

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 4.) Always assume that the tool contains fasteners 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 s econd fastener may be
driven possibly causing injury.

-4-

Do not remove, tamper with, or otherwise cause the tool, trigger, or contact trip to become
inoperable. Do not tape or tie trigger or contact trip in the on position. Do not remove
spring from contact trip. Make daily inspections for free movement of trigger and contact
trip. Uncontrolled discharge could result.

Do not alter or modify the tool in any way.
Make sure hose is free of obstructions or snags. Entangled or snarled hoses can cause

loss of balance or footing. Do not lift, pull or lower tool by the hose.
Use the tool only for its intended use. Do not discharge fasteners into open air, concrete,

stone, extremely hard woods, knots or any material too hard for the fastener to penetrate.
Do not use the body of the tool or top cap as a hammer. Discharged fasteners may follow
unexpected path and cause injury.

Always operate the tool in a clean, lighted area. Be sure the work surface is clear of any
debris and be careful not to lose footing when working in elevated environments such as
rooftops.

Grip tool firmly to maintain control while allowing tool to recoil away from work surface as
fastener is driven. In “Contact Actuation Mode” if contact trip is allowed to recontact work
surface before trigger is released an unwanted fastener will be fired.

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, 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.

Never use rafter hook to hang tool from body, clothing or belt.
Always verify and be aware of tool operating mode by inspecting the trigger before

connecting to an air supply and/or using the tool.

MAINTAINING THE TOOL

When working on air tools note the warnings in this manual and use extra care when
evaluating problem tools.

TOOL AIR FITTING:

This tool uses a 3/8" N.P.T. male plug. 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/cm2). Select the operating pressure within this range for best fastener
performance.

DO NOT EXCEED THIS RECOMMENDED OPERATING PRESSURE.

AIR CONSUMPTION:

These nailers require 6.4 cubic feet per minute (181 liters per minute) of free air to operate in sequential trip
mode 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 6.4 c.f.m. (181 liters per minute) which is required to operate the tool at 100
nails per minute.

OPERATING MODES

BOSTITCH OFFERS TWO MODES OF OPERATION FOR THIS TOOL.

SEQUENTIAL TRIP:

The Sequential Trip requires the operator to hold the tool against the work surface 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 placement 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 second fastener if the tool is contacted against the work – or anything else – while
the operator is holding the trigger pulled.

CONTACT TRIP:

The common operating procedure on “Contact Trip” tools is for the operator to contact the work surface
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 re-contact the work surface with the trigger still actuated (finger still
holding trigger pulled) an unwanted second fastener will be driven.

MODE IDENTIFICATION:

Refer to Tool Operation Instructions on pages 9-11 before proceeding to use this tool.

-6-

TO CHANGE OPERATING MODES:

Disconnect air line from tool and remove fasteners from magazine before making
adjustments or personal injury may result.

Always know the tool operating mode before connecting to an air supply and/or using the
tool.

SEQUENTIAL TRIP-

1. Push and hold in pivot pin opposite the selector, while rotating the selector 180° counterclockwise to the
sequential trip position .

2. Ensure the selector is fully seated in the new position.

Pivot Pin

Selector

To operate the nailer in sequential trip mode:

1. Depress the contact trip firmly against the work surface.

2. Depress the trigger.

A nail will fire each time the trigger is depressed as long as the contact trip remains
depressed.

CONTACT TRIP -

1. Push and hold in pivot pin while rotating the selector 180° clockwise to the contact trip position .

2. Ensure the selector is fully seated in the new position.

To operate the nailer in contact trip mode:

1. Depress the trigger.

2. Push the contact trip against the work surface. As long as the trigger is depressed, the tool will fire a nail
every time the contact trip is depressed. This allows the user to drive multiple nails in sequence.

Do not keep trigger depressed when tool is not in use.

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 connect tool to any air supply which could potentially exceed
200p.s.i.g.(14kg/cm

2

).

FITTINGS:

Install a male plug on the tool which is free flowing and which will release air pressure from the tool when
disconnected from the supply source.

HOSES:

Air hoses should have a minimum of 150 p.s.i. (10.5 kg/cm2) working pressure rating or 150 percent of the
maximum pressure that could be produced in the air system. The supply hose should contain a fitting that will
provide “quick disconnecting” from the male plug on the tool.

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.

-7-

REGULATOR:

A pressure regulator with an operating pressure of 0 - 125 p.s.i.g. (0 - 8.79 kg/cm2) is required to control the
operat ing 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:

An in-line 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. Use BOSTITCH Air Tool Lubricant,
PREMOIL, 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. 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, WINTEROIL, or permanent
antifreeze (ethylene glycol) as a cold weather lubricant.

NOTICE: 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.

NOTICE: Some commercial air line drying liquids are harmful to “O”-rings and seals – do not use these
low temperature air dryers without checking compatibility.

LOADING THE TOOL

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.

There are two available operation modes on these BOSTITCH pneumatic tools. They are:

1. SEQUENTIAL TRIP OPERATION

2. CONTACT TRIP OPERATION

BOSTITCH offers two types of operating modes which function differently: Sequential Trip and Contact Trip.
Each mode has specific advantages. You should evaluate your particular construction project to determine
which mode is best.

Always verify and be aware of tool operating mode by inspecting the trigger before
connecting to an air supply and/or using the tool.

1. SEQUENTIAL TRIP OPERATION:

The Sequential Trip (Mode) gets its name from the “sequence” required to drive a fastener. To drive a fastener,
the operator must first depress the “trip” FULLY against the work surface and then pull the trigger. To drive a
second nail, the operator must lift the tool from the work surface, release the trigger and then repeat the above
sequence.

A. The Sequential Trip (Mode): offers a positive safety advantage since it will not

accidentally drive a fastener if the tool is bumped against any surface or anybody
while the operator is holding the tools with the trigger pulled.

B. The Sequential Trip (Mode): allows “place nailing” without the possibility of driving

a second, unwanted fastener on recoil as described below under “Contact Trip”.

-10-

2. CONTACT TRIP OPERATION:

Your new BOSTITCH tool can be configured for use in Contact Trip “Conventional trip” mode. To drive a nail, the
“trip” and the trigger must both be depressed. In conventional Contact Trip tools, the trigger may be depressed
and held, and each “contact” between the trip and the work surface will drive a nail.

A. SINGLE FASTENER PLACEMENT (Place Nailing) – First position the “trip”

FULLY on the work surface, WITHOUT PULLING THE TRIGGER. Depress the “trip”
FULLY until the nose of the tool touches the work surface and then pull the trigger
to drive a nail. Do not press the tool against the work surface with extra force.
Instead, allow the tool to recoil off the work surface to avoid a second unwanted
fastener. Note: remove your finger from the trigger after each operation.

B. RAPID FIRE OPERATION (“Bump” Nailing) – First, hold the tool with the “trip” pointing towards but not

touching the work surface. Pull the trigger and then tap or “bump” the trip against the work surface using
a bouncing motion. Each depression of the “trip” will cause a nail to be driven.

The Contact Trip will not prevent a nail from being accidentally driven if the trigger is
depressed and the “trip” is bumped against any object or person. Never hold or carry
the tool with your finger on the trigger. Only depress and hold trigger when you intend to
rapidly drive multiple nails and the tool is pointed at the work surface.

When using conventional Contact Trip for Place Nailing, the tool may bounce due to
recoil, and if the tool is allowed to re-contact the work surface while you are holding the
trigger pulled, a second unwanted nail will be driven. You should allow the tool to recoil
far enough to release the trip and avoid a second cycle. Don’t push the tool down extra
hard; let the tool do the work.

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.

Never use rafter hook to hang tool from body, clothing or belt.

TOOL OPERATION CHECK:

Remove all fasteners from tool before performing tool operation check.

SEQUENTIAL TRIP OPERATION:

A. Press the contact trip against the work surface, without touching the trigger.
THE TOOL MUST NOT CYCLE.
B. Hold the tool off the work surface and pull the trigger.
THE TOOL MUST NOT CYCLE.

Release the trigger. The trigger must return to the trigger stop on the frame.
C. Pull the trigger and press the contact trip against the work surface.
THE TOOL MUST NOT CYCLE.

D. With finger off the trigger, press the contact trip against the work surface. Pull the trigger.
THE TOOL MUST CYCLE.

2. CONTACT TRIP OPERATION:

A. With finger off the trigger, press the contact trip against the work surface.
THE TOOL MUST NOT CYCLE.
B. Hold the tool off the work surface, and pull the trigger.
THE TOOL MUST NOT CYCLE.
C. With the tool off the work surface, pull the trigger. Press the contact trip against the work surface.
THE TOOL MUST CYCLE.
D. Without touching the trigger, press the contact trip against the work surface, then pull the trigger.
THE TOOL MUST CYCLE.

IN ADDITION TO THE OTHER WARNINGS CONTAINED IN THIS MANUAL
OBSERVE THE FOLLOWING FOR SAFE OPERATION

• Use the BOSTITCH pneumatic tool only for the purpose for which it was designed.

• Never use this tool in a manner that could cause a fastener to be directed toward the user or
others in the work area.

• Do not use the tool as a hammer.

• Always carry the tool by the handle. Never carry the tool by the air hose.

-11-

• Do not alter or modify this tool from the original design or function without approval from
BOSTITCH.

• Always be aware that misuse and improper handling of this tool can cause injury to yourself
andothers.

• Never clamp or tape the trigger or contact trip in an actuated position.

• Never leave a tool unattended with the air hose attached.

• Do not operate this tool if it does not contain a legible WARNING LABEL.

• Do not continue to use a tool that leaks air or does not function properly. Notify your nearest
BOSTITCH representative if your tool continues to experience functional problems.

MAINTAINING THE PNEUMATIC TOOL

When working on air tools, note the warnings in this manual and use extra care evaluating

problem tools.

Pusher spring (constant force spring). Caution must be used when working with the
spring assembly. The spring is wrapped around, but not attached to, a roller. If the spring
is 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 cut. Care must also be taken to insure no permanent kinks are put in the
spring as this will reduce the springs force.

REPLACEMENT PARTS:

Use only Genuine OEM replacement parts.

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.

TROUBLE SHOOTING

To reduce the risk of serious personal injury, remove fasteners from magazine before

making any adjustments or servicing this tool.
