Use only nails specified in this manual. The use of
any other nails may cause malfunction of the tool.
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
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
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 nailing operations immediately if you notice
something wrong or out of the ordinary with the
tool.
U
*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 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.
When not operating the tool, always lock the trigger
by turning the lock knob (lock pin).
Ask Makita's Factory or Authorized service center
for periodical inspection of the tool.
To maintain product SAFETY and RELIABILITY,
maintenance and repairs should be performed by
Makita Authorized or Factory Service Centers,
always using Makita replacement parts.

TOOL INSTALLATION INSTRUCTIONS AND USE
Selecting compressor
The air compressor must comply with the requirements of
ANSI 819.3 - 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 at a rate of approximately 5 0 times per minute at a
compression of 5 kgf/cm2G (70 PSIG), a compressor with
an air output over 30 literdminute is required. Pressure
regulators must be used t o limit air pressure t o 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 t o tool operator or persons in the vicinity.

(timesh")
Selecting air hose
Use an air hose as large and as short as possible t o assure
continuous, efficient nailing operation. With an air pressure
of 5 kgf/cm2G ( 7 0 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.
CAUTIO N:
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.
Lubrication
To insure maximum performance, install an air set (oiler,
regulator, air filter) as close as possible t o the tool. Adjust
the oiler so that one drop of oil will be provided for every
5 0 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.

Nose adapter
CAUTION:
Always lock the trigger and disconnect the hose before installing or removing the nose adapter.
To prevent the workpiece from being damaged or scratched,
attach the nose adapter to the contact arm so that the
protrusion of the nose adapter will fit into the hole in the
contact arm.

Loading nailer
CAUTION:
Always lock the trigger and disconnect the hose before loading the nailer.
To open the slide door, pull it toward you while depressing
the lever.
Load nails into the magazine so that the nail points will be
set into the groove at the bottom of the magazine. Move
the nails into the ejection slot as far as they will go. (Follow
the No. 1, 2 and 3 procedures in order as shown in the figure
at right.)
igazine
CAUTION:
Always load the same type and size of nail into the magazine. If you load the tool with different types and/or sizes
at the same time, a malfunction may result.
Groove
Driver guide
To close the slide door, slide it toward the driver guide until the slide door is locked.
Adjusting depth of nailing
CAUTION:
Always lock the trigger and disconnect the hose before adjusting the depth of nailing.
Adjust the depth of nailing by turning the adjuster. The
depth of nailing is the deepest when the adjuster is set at
the 2.5 graduation. It will become shallower as the adjuster
is set to a lower graduation. The depth can be changed in
approx. 0.5 mm (1/64") increments per graduation.
If nails are driven too deep even when the adjuster is set
to 0 graduation, decrease the air pressure. If nails cannot
be driven deep enough even when the adjuster is set to 2.5
graduation, increase 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 higher
graduation.
Connecting air hose
Lock the trigger. 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.
Operation
This tool offers two types of operation: Sequential Activation and Trigger Activation. Sequential
Activation requires the operator to hold the tool against the workpiece before pulling the trigger. Trigger
Activation allows the tool to operate by actuation of the trigger only.
First, release the trigger by turning the lock knob (lock pin) and proceed to the following.
Sequential activation
1. Place the contact arm against the workpiece.

Trigger activation
1. Place the contact arm against the workpiece.
Turn the activation lever to the "Trigger Activation" position.
2. Depress the contact arm against the workpiece and pull the trigger to drive a nail. As soon as the
nail is driven, release the trigger.
3. Slide the contact arm over the workpiece surface to the next driving position.
4. Then pull the trigger to drive another nail.
5. After the desired number of nails have been driven, turn the activation lever to the "Sequential
Activation" position while keeping the contact arm depressed against the workpiece.
WARN ING :
Be very careful when using the Trigger Activation, since the tool will operate only by the trigger
action.
Never use Trigger Activation except when performing continuous nailing without removing the
contact arm from work surface.
When nails are depleted, the trigger cannot be pulled because a mechanism actuates. Load nails
into the magazine, and the trigger can now be pulled.
CAUTION:
The mechanism cannot actuate when the slide door is open. So always lock the trigger by turning
the trigger lock knob to prevent accidental firing when the slide door is open.
*Operating the tool without nails shortens the life of the tool and should be avoided.
Air exhaust
Air exhaust direction can be changed easily by rotating the
exhaust cover. Change it when necessary.
