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
pressedagainst the wood.
It must work only when
bothactions are performed. Test for possible faulty
operation
with nails unloaded and with the pusher
locked at fully pulled position.

.Make sure no one is nearby before nailing. Never
attempt to nail from boththe inside and outside at
thesametime. Nails may ripthrough and/or fly off,
presenting a grave danger.
Watch your footingand 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 performnailing operations
with less
fatigue by doing
so.
A nail will be bent or the tool can becomejammed
if you mistakenly nailontopof another nailor strike
a knot
in thewood. The nailmay bethrownand hit
someone, or the tool itself can react dangerously.
Place the nails
with care.
Hold the workpiece securely. Under nailer impact,
the workpiece canfly about dangerously
if not held
securely
in place.
Do not leave the loaded tool or the air compressor
underpressurefor a longtime out
in thesun. Be sure
that dust, sand, chips and foreign matter
will not
enter thetool
in the placewhere you leave it setting.

.Do not point the ejection port at anyone in the
vicinity. Keep handsandfeet awayfrom 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 (droppingor 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.
Performcleaningand maintenanceright after finish-
ing the job. Keep the tool
in tip-top condition.
Lubricate moving parts to prevent rusting and
minimizefrictionrelatedwear. 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 the 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 the air
set oiler is not used, oil with a few drops
of turbine oil through the air plug both before and
after nailing operations. Simply
oil before use, but
when oiling after use, operate the tool several times
to assure good lubrication. This makes certain the oil
works into and throughout the tool to prevent rust-
ing. When using the tool for
a long time, oil during
nailing operations.
Loadingnailer
CAUTION:
Always disconnect the air hose before loading the nails intothe nailer

Insert strip of nails into the magazine. Two strips of
nails can be loaded
at a time.
Make sure that when loading the second strip the first
nail of the second strip
sets on (overlaps) the last nail
of the first strip.

While pulling the pusher, press the lock lever to unlock
the pusher. Then return the pusher while pressing the
lock lever.
I
Selecting compressor
The air compressor shall comply with the requirements
Select a compressor that has ample high pressure and
air output in order to assure cost-efficient operation.
The tool should not be connected to
a source whose
pressure potentiallyexceeds
14.0 kgf/cm2 G (200 PSIG).
The graph
at right shows the relation between nailing
frequency, applicable pressure and compressor air out-
put. Thus, for example, if the nailing takes place
at a
speed of approximately 60 times per minute at a com-
pression of
5 kgf/cm*G (70 PSIG), a compressor with
of ANSI 519.3
- 1981.
Use an air hose
as thick and as short as possible to
assure continuous, efficient nailing operations. With an
air pressure of
5 kgf/cm2 G (70 PSIG),an air hose with
an internal diameter of over 8.5mm
(1 1/32") 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 pres-
sure rating of
10.7 kgf/cm2G (150 PSIG) or 150 per-
cent of the maximum pressureproduced in the system
whichever
is higher.

When the nailer becomes jammed, do as follows:
First, disconnect the air hose. Remove the strip of
nails. Insert
a small rod or the like into the ejection
port and tap
it with a hammer to retract the driver.
Use pliers to bend the jammed nail
so that the nail
head comes out
of the slot in the driver guide. Then
remove the jammed nail.

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
loosescrews before operation. Tighten
as required.
Make sure
all safety systems are in working order
before operation.The tool must not operate ifonly the
trigger is pulled or if only the contact arm
is pressed
against the wood. Itmust work only when both actions
are performed. Test for possible faulty operation with
nails unloaded and with the pusher locked
at fully
pulled position.
Pusher
When not using the tool for a long period, coat metal
parts lightly with machine oil to prevent rust. Avoid
storing the tool in
a very humid or hot place or place
exposed to direct sunlight.

Maintenance of compressor, air set and air hose
After operation, always drain the compressor tank and
the air filter. If the tool is used without the water thus
drained, poor performance and
a possible breakdown
can result.
Check regularly to
see if there is sufficient turbine oil
in the oiler
of the air set. Failure to have sufficient
lube will cause fast O-ringwear, when the
tool is used.
Keep the air hose away from heat (over 60°C, over
140" F), chemicals (thinner, strong acids or alkalis)
and possibledamage.
