MAINTAINING THE TOOL
WARNING:
!
CAUTION:
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 Z87.1-1979 and provide both frontal and side protection. NOTE: Non-side
shielded spectacles and face shields alone do not provide adequate protection.
EAR PROTECTION may be required in some environments. As the working area may
include exposure to high noise levels which can lead to hearing damage, the employer
and user should ensure that any necessary hearing protection is provided and used by
the operator and others in the work area.
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.

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.
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 fas-
tener. 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.
There are three available systems on STANLEY-BOSTITCH pneumatic tools. They are:
1. TRIGGER OPERATION 2. CONTACT TRIP OPERATION 3. SEQUENTIAL TRIP OPERATION
WARNING:
!
WARNING:
!
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.

BASIC TOOL OPERATION
MAINTAINING THE PNEUMATIC TOOL
When working on air tools, note the warnings in this manual and use extra care
evaluating problem tools.
CAUTION: 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:
STANLEY-BOSTITCH replacement parts are recommended. Do not use modified parts or parts which will not
give 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
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 STANLEY-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.

AIR SUPPLY AND CONNECTIONS
WARNING:
!
Do not use oxygen, combustible gases, or bottled gases as a power source for this tool as
tool may explode, possibly causing injury.
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. (10.6 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.
REGULATOR:
A pressure regulator with an operating pressure of 0 - 125 p.s.i. is required to control the operating pressure for
safe operation of this tool. Do not connect this tool to air pressure which can potentially exceed 200 p.s.i. 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 STANLEY-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 STANLEY-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 compatability.

T40 TOOL SPECIFICATIONS
All screws and nuts are metric.
TOOL AIR FITTING:
This tool uses a 1/4” N.P.T. male plug. The inside diameter should be .200” (5mm) 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 T40 requires 2.6 cubic feet per minute (73.6 liters per minute) of free air to operate at the rate of 100 staples
per minute, at 80 p.s.i. (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 staples per minute, you need 50% of the 2.6 c.f.m.
(73.6 liters per minute) which is required to operate the tool at 100 staples per minute.
STANLEY-BOSTITCH OFFERS THREE 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.
TRIGGER OPERATED
The Trigger Operated model is cycled by actuation of the trigger only. This model does not have a Contact Arm
and is intended for use only where a Contact Arm CANNOT be used to satisfy the requirements of the application.
The Trigger Operated tool will cycle each time the trigger is actuated.

Models T40S2, T40S4, T40S5, and T40SX contain a Quick Release Door feature. The door is designed
to “pop” open if a jam occurs providing easy access for removing a jammed fastener.
ALWAYS DISCONNECT AIR SUPPLY BEFORE CLEARING A JAMMED FASTENER.
If the door does not “pop” open when a jam occurs, it can easily be opened with a screwdriver, as shown in illustration #1.
Use a firm twist on the screwdriver to open the door, see illustration #2.
The door will not open completely if the driver is still down. To open the door completely the driver must be pushed back
into the tool.
The “Quick Release Door” makes cleaning the nose and front portion of the magazine a rapid and easy operation with
a minimum of effort.
To close the door simply press the door firmly against the edge of the work table or suitable stationary object until the two
latch pins snap into a locked position.
CAUTION: Do not use your hands to close the door as injury may occur if skin is pinched between the door and
nose when the latch pins engage.
WARNING:

CLEANING T40S2 STAPLERS
USED WITH ASPHALT SHINGLES
Tar and dirt may build up on the nose and contact arm. This can prevent
correct operation. Remove any buildup with kerosene, #2 fuel oil or diesel
fuel. Do not immerse the stapler into these solvents beyond the bottom of
the frame to avoid getting the solvent into the drive cylinder.
As an aid in cleaning or to help remove a jam if necessary, the nose may be opened by
inserting a screwdriver into the drive channel and prying to pop open the door.
Dry off the stapler before use. Any oil film left after cleanup will accelerate
the tar buildup, and the stapler will require more frequent re-cleaning.
WARNING:
!
Do not use gasoline or similar highly flammable liquids to clean the tool.
Vapor in the tool could be ignited by a spark causing the tool to explode.
NOTE: Solvents sprayed on nose to clean and free up the trip may have the opposite effect!
The solvent may soften the tar on the shingles and cause tar buildup to be accelerated. Dry
operation is better, as noted above.
