IMPORTANT SAFETY INSTRUC-
TIONS
WARNING: WHEN USING THIS TOOL, BASIC
SAFETY PRECAUTIONS SHOULD ALWAYS BE FOL-
LOWED TO REDUCE THE RISK OF PERSONAL
INJURY, INCLUDING THE FOLLOWING:
READ ALL INSTRUCTIONS.
• For personal safety and proper operation and
maintenance of the tool, read this instruction man-
ual before using the tool.
• Always wear safety glasses to protect your eyes
from dust or nail injury.
WARNING:
It is an employer’s responsibility to enforce the use
of safety eye protection equipment by the tool
operators and by other persons in the immediate
working area.
• For Australia and New Zealand only
Always wear safety glasses and face shield to pro-
tect your eyes from dust or nail injury. The safety
glasses and the face shield should conform with
the requirements of AS/NZS 1336.
WARNING:
It is an employer’s responsibility to enforce the use
of safety eye protection equipment by the tool
operators and by other persons in the immediate
working area.
• 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 fasten-
ers.
(2) Do not point the tool toward yourself or any-
one 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.
(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 lev-
els within prescribed limits. In certain cases, shut-
ters 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 inop-
erable, disconnected, altered, or not working prop-
erly.
• Operate the tool within the specified air pressure of
0.39 - 0.78 MPa (3.9 - 7.8 bar) for safety and
longer tool life. Do not exceed the recommended
max. operating pressure of 0.78 MPa (7.8 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 com-
pressed 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 SPECIFI-
CATIONS).
• 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 nails 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 nails specified in this manual. The use of
any other nails 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, lad-
ders, 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 nailing. Never
attempt to nail from both the inside and outside at
the same time. Nails 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, nail as you
move forward. It is easy to lose your footing if you
nail while inching backward. When nailing against
perpendicular surface, nail from the top to the bot-
tom. You can perform nailing operations with less
fatigue by doing so.
•A nail will be bent or the tool can become jammed
if you mistakenly nail on top of another nail or strike
a knot in the wood. The nail may be thrown and hit
someone, or the tool itself can react dangerously.
Place the nails 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 ejec-
tion 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 nailing operations immediately if you notice
something wrong or out of the ordinary with the
tool.
•Always disconnect the air hose and remove all of
the nails:
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 fin-
ishing the job. Keep the tool in tip-top condition.
Lubricate moving parts to prevent rusting and mini-
mize friction-related wear. Wipe off all dust from
the parts.
•Do not operate this tool if it does not contain a legi-
ble WARNING LABEL.
•Do not modify tool without authorization from Mak-
ita.
•Ask Makita’s Authorized service centers for period-
ical 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 man-
ual.
•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. Nails may be driven accidentally if the
safety mechanism is not working correctly.

INSTALLATION
Selecting compressor
•Select a compressor that has ample pressure and air output to assure
cost-efficient operation. The graph shows the relation between nailing
frequency, applicable pressure and compressor air output. Thus, for
example, if nailing takes place at a rate of approximately 60 times per
minute at a compression of 0.69 MPa (6.9 bar), a compressor with an air
output over 60 L/min 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.
Selecting air hose
•Use an air hose as large and as short as possible to assure continuous,
efficient nailing operation. With an air pressure of 0.49 MPa (4.9 bar), an
air hose with an internal diameter of over 6.5 mm (1/4”) and a length of
less than 20 m (6.6 ft.) is recommended when the interval between each
nailing is 0.5 seconds. Air supply hoses shall have a minimum working
pressure rating of 1.03 MPa (10.3 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 nailing frequency may cause a decrease in the driving
capability of the tool.
Lubrication
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 pro-
vided for every 50 nails.
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 pneu-
matic tool oil is introduced.

FUNCTIONAL
DESCRIPTION CAUTION:
•Always disconnect the hose before adjusting or checking function on the
tool.
Adjusting depth of nailing
To adjust the depth of nailing, turn the adjuster. The depth of nailing is the
deepest when the adjuster is turned fully in the A direction shown in the figure.
It will become shallower as the adjuster is turned in the B direction. If nails
cannot be driven deep enough even when the adjuster is turned fully in the A
direction, increase the air pressure. If nails are driven too deep even when the
adjuster is turned fully in the B direction, decrease the air pressure. Generally
speaking, the tool service life will be longer when the tool is used with lower air
pressure and the adjuster set to a lower depth of nail driving.
CAUTION:
•Always disconnect the hose before adjusting the depth of nailing.
Hook
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.
ASSEMBLY CAUTION:
•Always disconnect the hose before carrying out any work on the tool.
•Load the same kind, size and uniform length of nails when loading nails
in the magazine.

Nose adapter
CAUTION:
•Always disconnect the hose before installing the nose adapter.
To prevent the surface of workpiece from being scratched or damaged, use
the nose adapter by fittiing the protrusion of the inside of nose adapter with the
notch in the contact arm.
Store the nose adapter in place when not in use. The place for storage is on
both sides of the tool and inside the carrying case.
Connecting air hose
Slip the air socket of the air hose onto the air fitting on the nailer. 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 pres-
sure reservoir will discharge at the time the air supply coupling is discon-
nected.

OPERATION
To drive a nail, you may place the contact element against the workpiece and
pull the trigger.
CAUTION:
•WITH THE TRIGGER HELD IN A HALF-PULLED POSITION, an
unexpected nailing 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 nailing, 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 nailing.
Direction of exhaust air
The direction of exhaust air can be changed 360 degrees of angle by turning
the exhaust cover with a hand.
Removing nails
CAUTION:
•Do not use deformed nails or nail strip. Failure to do so causes poor nail
feeding.
WARNING:
•Always disconnect the hose before removing nails.
Open the slide door and remove nails from the magazine.
With the slide door kept open, open the door and take out nails.

Removing the contact top allows nails to be easily taken out. When re-install-
ing the contact top, insert the prorusion of the contact top into the notch in the
contact arm.
Nails
Handle nail coils and their box carefully. If the nail coils have been handled
roughly, they may be out of shape or their connector breaks, causing poor nail
feed.

MAINTENANCE CAUTION:
•Always disconnect the hose before attempting to perform inspection or
maintenance.
Maintenance of nailer
Always check the tool for its overall condition and loose screws before opera-
tion. Tighten as required.
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.
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.

Maintenance of compressor, air set and air hose
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.
Keep the air hose away from heat (over 60°C, over 140°F), away from chemi-
cals (thinner, strong acids or alkalis). Also, route the hose away from obstacles
which it may become dangerously caught on during operation. Hoses must
also be directed away from sharp edges and areas which may lead to damage
or abrasion to the hose.
To maintain product SAFETY and RELIABILITY, repairs, any other mainte-
nance and adjustment should be performed by Makita Authorized Service
Centers, always using Makita replacement parts.
