OPERATION

b. To change shallow clinchers (see part charts for

part numbers) remove screws and front bracket
to provide access to clinchers. Change one at a
time to prevent reversing part. Also part #45
(See Figure 3) will need to be changed to
specified spacer in the table.

Figure 3

2. Pull back the pusher until it is tucked under the rear
of the magazine in position 1. (See Figure 1)

3. Check staple leg length – Adjustment is provided in
the H-3532/H-3534 for different staple leg lengths.

a. To adjust machine for leg length, loosen set

screw (See Figure 2) and turn pivot pin 180º with
a screwdriver to the desired adjustment as noted.
Tighten set screw.

NOTE: Remove adjusting tool after adjustment.

7. Depth Adjustment – Loosen front screw and adjust
to desired length (See Figure 6). When the top edge
of adjustment plate is at highest setting (#4), the
clinchers are at their shallowest penetration. If set at
lowest setting (#1), the clinchers are at their deepest
penetration.

USING THE STAPLER

Stapling – Grasp handle with one hand. Position on

box in line with the desired staple location. There is a
small projection on either side of the frame as an aid in
locating the position of the staple (See Figure 7). Press
trigger. Strongest closure requires end staples close to
end of box. Check packaging requirements. Test staple
clinching in a sample of the board being used. Adjust
clinch for depth of penetration and tightness.

Figure 7

NOTE: Always disconnect air supply:

1. Before making adjustments;

2. When servicing the stapler;

3. When clearing a jam;

4. When stapler is not in use;

5. When moving to a different work area,
as accidental actuation may occur,
possibly causing injury.

SAFETY WARNINGS

OPERATION

WARNING! Always handle the stapler with care:

1. Never engage in horseplay. 2. Never pull
the trigger unless nose is directed toward the
work. 3. Keep others at a safe distance from
the stapler while in operation as accidental
actuation may occur, possibly causing injury.

WARNING! Keep hands and body away from
the discharge area of the stapler.

WARNING! Do not drive fasteners on top of
other fasteners or with the stapler at an overly
steep angle as this may cause deflection of
fasteners which could cause injury.

WARNING! This stapler produces SPARKS
during operation. NEVER use the stapler near
flammable substances, gases or vapors
including lacquer, paint, benzene, thinner,
gasoline, adhesives, mastics, glues or any
other material that is – or vapors which are –
flammable, combustible or explosive. Using the
stapler in any such environment could cause
an EXPLOSION resulting in personal injury or
death to user and bystanders.

CAUTION: Remove all fasteners from the stapler
before performing stapler operation check.

TRIGGER-OPERATED STAPLER

a. With finger off the trigger, hold the stapler with a

firm grip on the handle.

b. Place the nose of the stapler against the work.

3. Clear the jam and reinsert the magazine. Pry jam
release shut. (See Figure 10)

WARNING! This is a full-cycle stapler. The stapler
will cycle each time the trigger is pulled!
Clinchers will discharge and retract.

EYE PROTECTION

WARNING! Eye protection which conforms to
ANSI specifications and provides protection
against flying particles from both the FRONT
and the SIDES should always be worn by the
operator and others in the work area when
connecting to air supply, loading, operating or
servicing this stapler. Eye protection is required
to guard against flying fasteners 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 and provide both frontal and side
protection.

NOTE: Non-side shielded spectacles and face
shields do not provide adequate protection.

AIR SUPPLY AND CONNECTIONS

WARNING! Do not use oxygen, combustible
gases or bottled gases as a power source
for this stapler, as the stapler may explode,
possibly causing injury.

WARNING! Do not use supply sources which
can potentially exceed 200 psig as stapler
may burst, possibly causing injury.

c. Pull the trigger to drive.

PAGE 3 OF 19 0421 IH-3532

SAFETY WARNINGS CONTINUED

WARNING! The connector on the stapler
must not hold pressure when air supply is
disconnected. If a wrong fitting is used, the
stapler 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.

WARNING! Do not pull trigger or depress
contact arm while connected to the air supply
as the stapler may cycle, possibly causing
injury.

WARNING! Always disconnect air supply.

In addition to the other warnings contained in this
manual, observe the following for safe operation:

• Use the Bostitch® pneumatic stapler only for the
purpose for which it was designed.

MAINTENANCE

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

• Do not use the stapler as a hammer.

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

• Do not alter or modify this stapler from the original
design or function without approval from Bostitch Inc.

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

• Never leave unattended with the air hose attached.

• Do not operate this stapler if it does not have a
legible WARNING LABEL.

• Do not continue to use a stapler that leaks air or
does not function properly. Notify Uline if your stapler
continues to experience functional problems.

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

REPLACEMENT PARTS

• 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 stapler, 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
reassemble add a few drops of Bostitch Air Tool
Lubricant through the air line fitting before sealing.

AIR SUPPLY - PRESSURE AND VOLUME

• Air volume is as important as air pressure. The air
volume supplied to the stapler may be inadequate
due to undersized fittings and hoses or from the
effects of dirt and water in the system. Restricted
air flow will prevent the stapler from receiving an
adequate volume of air even though the pressure
reading is high. The result will be slow operation,
misfeeds or reduced driving power.
Before evaluating stapler problems for these
symptoms, trace the air supply from the stapler to
the supply source for restrictive connectors, swivel
fittings, low points containing water or anything else
that would prevent full volume flow of air to
the stapler.

STAPLER AIR FITTING

This stapler must use a male free-flow connector plug,

1/4" (11mm) N.P.T. The minimum inside diameter should

be .300" (5mm). Fitting must be capable of discharging
stapler air pressure when disconnected from the air
supply.

OPERATING PRESSURE

The operating pressure of the stapler is 70 to 100 psi
(5 to 7 kg/cm2). Select the operating pressure within this
range for best fastener performance.

CAUTION: Do not exceed the recommended
operating pressure.

AIR CONSUMPTION

Model H-3532/H-3534 requires 4.0 cubic feet per minute
(.113 cubic meters) of free air to operate at the rate
of 100 fasteners per minute, at 80 psi (5.66kg/cm2).

Take the actual rate at which the stapler will be run to

determine the amount of air required. For instance, if
your fastener usage averages 50 fasteners per minute,
you need 50% of the stapler's cfm of free air which is
required for running at 100 fasteners per minute.
