SAFETY INSTRUCTIONS
WARNING: WHEN USING THIS TOOL, BASIC SAFETY PRECAUTIONS
SHOULD ALWAYS BE FOLLOWED 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 manual
carefully before using the tool.
Wear light but not loose clothing. Sleeves should be
buttoned or rolled up. No necktie should be worn.
.Always wear safety glasses to protect your eyes
from dust or nail injury. The safety glasses should
conform with the requirements of ANSI 287. 1 1979. Also wear hearing protection to protect your
ears against exhaust noise.
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.
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.Never depress the operating control unless the
nosepiece of the tool is directed toward the
workpiece.
4. Respect the tool as a working implement.
5. No horseplay.
U
6. Do not transport the tool with the operating control depressed.
7. Do not load the tool with fasteners with the work-contacting element or operating control depressed.
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 tamper with the tool or attempt to use it for
other than nailing. 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.
-Contact
Operate the tool within the specified air pressure of
4.0 - 8.5 kgf/cm*G (60 - 120 PSIG) for safety
and longer tool life. Do not exceed the recommended
max. operating pressure of 8.5 kgf/cm’G (120
PSIG). The tool should not be connected to a source
whose pressure potentially exceeds 14.0 kgf /cm’G
(200 PSIG).
120 PSIG
Never use the tool with other than compressed air.
If high-pressure gas (carbon dioxide, oxygen, nitrogen, 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 element
is pressed against the wood. It must work only when
both actions are performed. Test for possible faulty
operation with nails unloaded and with the pusher
locked at fully pulled position. (See page 11 for the
method of locking the pusher.)
*Check walls, ceilings, floors, roofing and the like
carefully to avoid possible electrical shock, gas
leakage, explosions, etc. caused by striking lives
wires, conduits or gas pipes.

... .
.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.
6
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
bottom. 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
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 before inspection, maintenance, relocating,
or after operation is over.
8
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.
Ask Makita’s Factory or Authorized service center
for periodical inspection of the tool.
SAVE THESE INSTRUCTIONS.
TOOL INSTALLATION INSTRUCTIONS AND USE
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 provided for every
30 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
pneumatic tool oil is introduced.

Loading nailer
CAUTION:
Always disconnect the air hose before loading nails into the nailer.
Select nails suitable for your work.
Insert strip of nails into the magazine. Two strips of nails
can be loaded a t a time.
Pull the pusher to the rear to engage it to the last nail.

Unloading nailer
CAUTION:
Always disconnect the air hose before unloading the nailer.
Pull the pusher fully to the rear and depress the lock button.
While keeping the lock button depressed, release your finger
from the pusher to lock the pusher with the lock button.
Point the rear of the magazine downward to remove the
strip of nails from the magazine.

If the strip of nails cannot be removed because it is caught
by the pusher, depress the pusher tab to disengage the strip
of nails from the pusher and remove it from the magazine.
To unlock the pusher, pull it to the rear again.
Adjusting depth of. nailing
CAUTION:
Always disconnect the air hose before adjusting the depth of nailing.
To adjust the depth of nailing, press the knob toward the
nose tip and turn the adjuster so that the arrow above the
adjuster will point to the number indicated on the adjuster.
The depth of nailing is the deepest when the arrow points
to the number 1. It will become shallower as the arrow
points to higher number. The depth can be changed in
approx. 0.8 mm (1/32") increments per graduation. If nails
cannot be driven deep enough even when the arrow points
to the number 1, increase the air pressure. If nails are driven
too deep even when the arrow points to the number 9,
decrease the air pressure.

Selecting compressor
The air compressor must comply with the requirements of
ANSI B19.3 - 1981.
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 a t a rate of approximately 3 0 times per minute at a
compression of 5 kgf/cm2G (70 PSIG), a compressor with
an air output over 3 0 liters/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.

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 5 kgf/cm2G (70 PSIG), an air hose with an internal diameter of over 6.5 m m (17/64") 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 10.7 kgf/cm2G (150
PSIG) 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 t o the nailing
frequency may cause a decrease in the driving capability of the tool.
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
pressure reservoir will discharge at the time the air supply
coupling is disconnected.

This tool has a mechanism to prevent firing when nails are depleted. However, the mechanism cannot
actuate when the pusher is pulled to the rear.
Jammed nailer
CAUTION:
Always disconnect the air hose before clearing a jam.
The door of this tool is designed to open automatically
when a jam occurs. If it does not open automatically, open
it by hand. To do so, first disconnect the air hose. Then pull
the door toward the tool body and open it.
If the door cannot be opened by hand, use a slotted screwdriver. Insert the screwdriver between the door and the
driver guide. Twist the screwdriver to pry open the door.

Nails
Handle nail strips and their box carefully. If the nail strips
have been handled roughly, they may be out of shape or
their connector breaks, causing poor nail feed.
Avoid storing nails in a very humid or hot place or place
exposed to direct sunlight.
MAINTENANCE
CAUTION:
Always be sure that the air hose is disconnected from the tool before attempting to perform inspection
or maintenance.
Maintenance of nailer
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 element is pressed against the
wood. It must work only when both actions are performed.
Test for possible faulty operation with nails unloaded and
with the pusher locked at fully pulled position.
r
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 a humid or hot environment.
Maintenance of compressor, air set and air hose
