• Wear hearing protection to protect your ears
against exhaust noise and head protection. Also
wear light but not loose clothing. Sleeves should
be buttoned or rolled up. No necktie should be
worn.
• Rushing the job or forcing the tool is dangerous.
Handle the tool carefully. Do not operate when
under the influence of alcohol, drugs or the like.
• General Tool Handling Guidelines:
(1) Always assume that the tool contains
fasteners.
(2) Do not point the tool toward yourself or
anyone whether it contains fasteners or not.
(3) Do not activate the tool unless the tool is
placed firmly against the workpiece.
(4) Respect the tool as a working implement.
(5) No horseplay.

5
(6) Do not hold or carry the tool with a finger on
the trigger.
(7) Do not load the tool with fasteners when any
one of the operating controls is activated.
(8) Do not operate the tool with any power
source other than that specified in the tool
operating/safety instructions.
• An improperly functioning tool must not be used.
• Sparks sometimes fly when the tool is used. Do not
use the tool near volatile, flammable materials
such as gasoline, thinner, paint, gas, adhesives,
etc.; they will ignite and explode, causing serious
injury.
• The area should be sufficiently illuminated to
assure safe operations. The area should be clear
and litter-free. Be especially careful to maintain
good footing and balance.
• Only those involved in the work should be in the
vicinity. Children especially must be kept away at
all times.
• There may be local regulations concerning noise
which must be complied with by keeping noise
levels within prescribed limits. In certain cases,
shutters should be used to contain noise.
• Do not play with the contact element: it prevents
accidental discharge, so it must be kept on and not
removed. Securing the trigger in the ON position is
also very dangerous. Never attempt to fasten the
trigger. Do not operate a tool if any controls is
inoperable, disconnected, altered, or not working
properly.
• Operate the tool within the specified air pressure of
0.44 - 0.83 MPa (4.4 - 8.3 bar) for safety and
longer tool life. Do not exceed the recommended
max. operating pressure of 0.83 MPa (8.3 bar).
The tool should not be connected to a source
whose pressure potentially exceeds 1.37 MPa
(13.7 bar).
• Make sure that the pressure supplied by the
compressed air system does not exceed the
maximum allowable pressure of the fastener
driving tool. Set the air pressure initially to the
lower value of the recommended allowable
pressure (see SPECIFICATIONS).
• Never use the tool with other than compressed air.
If bottled gas (carbon dioxide, oxygen, nitrogen,
hydrogen, air, etc.) or combustible gas (hydrogen,
propane, acetylene, etc.) is used as a power
source for this tool, the tool will explode and cause
serious injury.
• Always check the tool for its overall condition and
loose screws before operation. Tighten as
required.
• Make sure all safety systems are in working order
before operation. The tool must not operate if only
the trigger is pulled or if only the contact arm is
pressed against the wood. It must work only when
both actions are performed. Test for possible faulty
operation with staples unloaded.
• Check walls, ceilings, floors, roofing and the like
carefully to avoid possible electrical shock, gas
leakage, explosions, etc. caused by striking live
wires, conduits or gas pipes.
• Use only staples specified in this manual. The use
of any other staples may cause malfunction of the
tool.
• Never use fastener driving tools marked with the
symbol "Do not use on scaffoldings, ladders" for
specific application for example:
−when changing one driving location to
another involves the use of scaffoldings,
stairs, ladders, or ladder alike constructions,
e.g. roof laths;
−closing boxes or crates;
−fitting transportation safety systems e.g. on
vehicles and wagons.
• Do not permit those uninstructed to use the tool.
• Make sure no one is nearby before stapling. Never
attempt to staple from both the inside and outside
at the same time. Staples may rip through and/or
fly off, presenting a grave danger.
• Watch your footing and maintain your balance with
the tool. Make sure there is no one below when
working in high locations, and secure the air hose
to prevent danger if there is sudden jerking or
catching.
• On rooftops and other high locations, staple as you
move forward. It is easy to lose your footing if you
staple while inching backward. When stapling
against perpendicular surface, staple from the top
to the bottom. You can perform stapling operations
with less fatigue by doing so.
• A staple will be bent or the tool can become
jammed if you mistakenly staple on top of another
staple or strike a knot in the wood. The staple may
be thrown and hit someone, or the tool itself can
react dangerously. Place the staples with care.
• Do not leave the loaded tool or the air compressor
under pressure for a long time out in the sun. Be
sure that dust, sand, chips and foreign matter will
not enter the tool in the place where you leave it
setting.
• Do not point the ejection port at anyone in the
vicinity. Keep hands and feet away from the
ejection port area.
• When the air hose is connected, do not carry the
tool with your finger on the trigger or hand it to
someone in this condition. Accidental firing can be
extremely dangerous.
• Handle the tool carefully, as there is high pressure
inside the tool that can be dangerous if a crack is
caused by rough handling (dropping or striking).
Do not attempt to carve or engrave on the tool.
• Stop stapling operations immediately if you notice
something wrong or out of the ordinary with the
tool.

6
• Always disconnect the air hose and remove all of
the staples:
1.When unattended.
2.Before performing any maintenance or repair.
3.Before cleaning a jam.
4.Before moving the tool to a new location.
• Perform cleaning and maintenance right after
finishing the job. Keep the tool in tip-top condition.
Lubricate moving parts to prevent rusting and
minimize friction-related wear. Wipe off all dust
from the parts.
• Do not operate this tool if it does not contain a
legible WARNING LABEL.
• Do not modify tool without authorization from
Makita.
• Ask Makita's Authorized service centers for
periodical inspection of the tool.
• To maintain product SAFETY and RELIABILITY,
maintenance and repairs should be performed by
Makita Authorized Service Centers, always using
Makita replacement parts.
• Use only pneumatic tool oil specified in this
manual.
• Never connect tool to compressed air line where
the maximum allowable pressure of tool cannot be
exceeded by 10 %. Make sure that the pressure
supplied by the compressed air system does not
exceed the maximum allowable pressure of the
fastener driving tool. Set the air pressure initially to
the lower value of the recommended allowable
pressure.
• Do not attempt to keep the trigger contact element
depressed with tape or wire. Death or serious
injury may occur.
• Always check contact element as instructed in this
manual. Staples may be driven accidentally if the
safety mechanism is not working correctly.

Select a compressor that has ample pressure and air
output to assure cost-efficient operation. The graph
shows the relation between stapling frequency,
applicable pressure and compressor air output.
Thus, for example, if stapling takes place at a rate of
approximately 60 times per minute at a compression of
0.68 MPa (6.8 bar), a compressor with an air output over
90L/minute is required.
Pressure regulators must be used to limit air pressure to
the rated pressure of the tool where air supply pressure
exceeds the tool's rated pressure. Failure to do so may
result in serious injury to tool operator or persons in the
vicinity.

7
Selecting air hose
Fig.1
Use an air hose as large and as short as possible to
assure continuous, efficient stapling operation. With an
air pressure of 0.49MPa (4.9 bar), an air hose with an
internal diameter of over 8.5 mm and a length of less
than 20 m is recommended when the interval between
each stapling is 0.5 seconds. Air supply hoses shall
have a minimum working pressure rating of 1.0MPa (10
bar) or 150 percent of the maximum pressure produced
in the system whichever is higher.
CAUTION:
• Low air output of the compressor, or a long or
smaller diameter air hose in relation to the stapling
frequency may cause a decrease in the driving
capability of the tool.
Lubrication
Fig.2
To insure maximum performance, install an air set (oiler,
regulator, air filter) as close as possible to the tool.
Adjust the oiler so that one drop of oil will be provided for
every 50 staples.
When an air set is not used, oil the tool with pneumatic
tool oil by placing 2 (two) or 3 (three) drops into the air
fitting. This should be done before and after use. For
proper lubrication, the tool must be fired a couple of
times after pneumatic tool oil is introduced.
FUNCTIONAL DESCRIPTION
CAUTION:
• Always disconnect the hose before adjusting or
checking function on the tool.
Adjusting depth of stapling
Fig.3
To adjust the depth of stapling, loosen the bolt by using
the hex wrench provided with the tool and then slide the
depth adjusting plate up or down.
If staples cannot be driven deep enough, slide the
adjusting plate in the direction of arrow as shown in the
figure.
Fig.4
If the staples are driven too deep, slide the adjustinhg
plate in the direction of arrow as shown in the figure.
Fig.5
The depth can be adjusted 5 mm to the maximum.
Tighten the bolt securely at the right position after
adjusting.
ASSEMBLY
CAUTION:
• Always disconnect the hose before carrying out
any work on the tool.
Hook
Fig.6
CAUTION:
• Always disconnect the hose from the tool.
• Never hook the tool at high location or on
potentially unstable surface.
The hook is convenient for hanging the tool temporarily.
Secure the hook on the tool with the provided screw
using either of two holes in the hook as shown in the
figure.
Loading stapler
CAUTION:
• Always disconnect the hose before loading the
tool.
• Do not use deformed staples or staple strip. Failure
to do so causes poor staple feeding.
• Always use staples specified in this instruction
manual. Failure to do so causes poor staple
feeding.
• Always return the pusher slowly and gently while
holding it with a hand.
Select staples suitable for your work. Make sure that the
hose is disconnected from the tool.
1. Pull the pusher to the rear of magazine and hook
the groove in the pusher on the lock pin.
Fig.7
2. Insert strip of staples into the magazine. Two
strips of staples can be loaded.
Fig.8
3. Depress the lock pin lightly and pull the pusher to
unhook it.
With the lock pin depressed, return the pusher
slowly and gently to the original position.
Keep depressing the pusher until it passes
through.
Fig.9
Connecting air hose
Fig.10
Slip the air socket of the air hose onto the air fitting on
the stapler. Be sure that the air socket locks firmly into
position when installed onto the air fitting. A hose
coupling must be installed on or near the tool in such a
way that the pressure reservoir will discharge at the time
the air supply coupling is disconnected.

OPERATION
CAUTION:
• Make sure all safety systems are in working order
before operation.
1. Pull the trigger first and then place the contact
element against the workpiece.
Fig.11
Fig.12
2. To drive a staple, you may place the contact
element against the workpiece and pull the trigger,
or
No. 1 method is for continuous stapling.
No. 2 method is for intermittent stapling, when you wish
to drive a staple carefully and very accurately.
CAUTION:
• However when the tool is set to the "Intermittent
Staplling" mode, WITH THE TRIGGER HELD IN A
HALF-PULLED POSITION, an unexpected
stapling could occur, if contact element is allowed
to re-contact against the workpiece or the other
surface under the influence of recoil.
In order to avoid this unexpected stapling, perform
as follows;
A. Do not place the contact element against the
workpiece with excessive force.
B. Pull the trigger fully and hold it on for 1-2 seconds
after stapling.
For No. 2 method, the OPTIONAL SEQUENTIAL TRIP
TRIGGER (SINGLE SHOT PART) is used . Replace
the trigger part with this.
Direction of exhaust air
Fig.13
The direction of exhaust air can be changed 360
degrees of angle by turning the exhaust cover with a
hand.
Removing jammed staples
WARNING:
• Always disconnect the hose before removing
staplers.
Remove the staples from the magazine.
Lift up the latch on the top of driver guide by hand.
Fig.14
If the latch cannot be lift up by hand, insert a slotted bit
screwdriver in the gap between the latch and the door
and force it up.
Fig.15
Open the door and take out staples.
Fig.16
Place the latch spring on two hooks of the driver guide
and return it to its original position by pressing it.
Fig.17
CAUTION:
• If the tip of staple driver has worn, staple jamming
and shallow driving will tend to occur. When this
occurs, have it repaired by Makita Authorized
Service Centers.
MAINTENANCE
CAUTION:
• Always disconnect the air hose from the tool before
attempting to perform inspection or maintenance.
Maintenance of stapler
Always check the tool for its overall condition and loose
screws before operation. Tighten as required.
Fig.18
With tool disconnected, make daily inspection to assure
free movement of the contact element and trigger. Do
not use tool if the contact element or trigger sticks or
binds.
Fig.19
When the tool is not to be used for an extended period of
time, lubricate the tool using pneumatic tool oil and store
the tool in a safe place. Avoid exposure to direct sunlight
and/or humid or hot environment.
Fig.20
Fig.21
Maintenance of compressor, air set and air
hose
Fig.22
Fig.23
After operation, always drain the compressor tank and
the air filter. If moisture is allowed to enter the tool, It
may result in poor performance and possible tool failure.
Check regularly to see if there is sufficient pneumatic oil
in the oiler of the air set. Failure to maintain sufficient
lubrication will cause O-rings to wear quickly.
Fig.24
Keep the air hose away from heat (over 60°C, over
140°F), away from chemicals (thinner, strong acids or
alkalis). Also, route the hose away from obstacles which
it may become dangerously caught on during operation.
