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 actuate 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 operatingkafety 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.
3
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.

Shutter
*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 portion of the
tool operating controls is inoperable, disconnected, altered, or not working properly.
-~
Operate the tool within the specified air
pressure of 0.44 - 0.83 MPa (65
120
PSIG) for safety and longer tool life. Do not
exceed the recommended max. operating
pressure of 0.83 MPa (120 PSIG). The tool
should not be connected to a source whose
pressure potentlally exceeds 1.37 MPa (200
PSIG).

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.
5
Make sure that the trigger is locked when
the change lever is set to the LOCK position.

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.
6
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 andlor 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.
L
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.
7
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.
8
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 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 change lever to
the LOCK position.

TOOL INSTALLATION INSTRUCTIONS AND US€
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 40 times per minute at a compression of 0.49
MPa (70 PSIG). a compressor with an air output over
2 ft3/minuteis 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 (70 PSIG), 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 1.06 MPa (150 PSIG) or 150 percent of the
maximum pressure produced in the system whichever
is higher.
I
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
provided 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 pneumatic tool oil is introduced.

Lift and turn the coil support plate to set it to the graduations of the magazine. If the tool is operated with the
coil support plate set to the wrong step, poor nail feed
or malfunction of the tool may result.
coil support plate
Place the nail coil over the coil support plate. Uncoil
enough nails to reach the feed claw. Place the first
nail in the driver channel and the second nail in the
feed claw. The nail heads must be in the slot in the
feeder body. Place other uncoiled nails on feeder body
and attach them to the magnet. Be sure that nails are
in the feeder claw and are not bent. Then close the
magazine cap.

Adjusting depth of nailing
CAUTION:
Always lock the trigger and disconnect the hose before adjusting the depth of nailing.
To adjust the depth of nailing, 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. 1.0 mm
(1132”) 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 8,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 number.
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
1) To drive a nail, you may place the contact element
against the workpiece and pull the trigger, or
2) Pull the trigger first and then place the contact element against the workpiece.
No. 1 method is for intermittent nailing, when you wish
to drive a nail carefully and very accurately.
No. 2 method is for continuous nailing.

Continuous nailing and trigger locking method
For continuous nailing, set the change lever to the
”Continuous Nailing” position. For locking the trigger, set the change lever to the ”Lock” position.
Always make sure that the change lever is properly
set to the position.
CAUTION:
I
Operating the tool without nails shortens the life of the tool and should be avoided.

Jammed nailer
CAUTION:
Always lock the trigger, disconnect the hose and remove the nails from the magazine before cleaning
a jam.
When the nailer becomes jammed, proceed as follows:
Open the door and magazine cap and remove the nail
coil. Insert a small rod or the like into the ejection port
and tap it with a hammer to drive out the nail jamming the ejection port. Reset the nail coil and close
the magazine cap and door.

Hook
The hook is convenient for hanging the tool temporarily. This hook can be installed on either side of the
tool.
CAUTION:
=Always lock the trigger and disconnect the hose when hanging the tool using the hook.
=Always tighten the hook securing bolt firmly. Loose bolt may cause air leakage from the tool.
14
*Never hang the tool on a waist belt or the like.
Dangerous accidental firing may result.
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.

17
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 6OoC, over
14OOF), away from chemicals (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, maintenance and repairs should be performed by Makita
Authorized or Factory Service Centers, always using Makita replacement parts.
