IMPORTANT SAFETY INSTRUCTIONS ENB087-1
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 before using the tool.
•Always wear safety glasses and face shield to
protect your eyes from dust or nail injury. The
safety glasses and the face shield should con-
form 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 fas-
teners.
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 acti-
vated.
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 materi-
als such as gasoline, thinner, paint, gas, adhe-
sives, 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 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 inopera-
ble, disconnected, altered, or not working prop-
erly.
•Operate the tool within the specified air pres-
sure of 0.44 - 0.83 MPa (4.4 - 8.3 bar) for safety
and longer tool life. Do not exceed the recom-
mended max. operating pressure of 0.83 MPa
(8.3 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
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 pres-
sure (see SPECIFICATIONS).
•Never use the tool with other than compressed
air. If bottled gas (carbon dioxide, oxygen, nitro-
gen, 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 oper-
ate if only the trigger is pulled or if only the con-
tact arm is pressed against the wood. It must
work only when both actions are performed.
Test for possible faulty operation with nails
unloaded and the pusher in fully pulled position.
•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.
•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, ladders, 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 bottom. You can perform nailing opera-
tions 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 compres-
sor 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 pres-
sure 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
finishing the job. Keep the tool in tip-top condi-
tion. 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.
•Do not operate this tool if it does not contain a
legible WARNING LABEL.
•Do not modify tool without authorization from
Makita.
•Ask Makita’s Authorized service centers for peri-
odical 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.

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 50 times per
minute at a compression of 0.59 Mpa (5.9 bar), a compressor with an air
output over 80 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 0.49 Mpa (4.9 bar), an
air hose with an internal diameter of over 6.5 mm 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 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.
FUNCTIONAL
DESCRIPTION
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 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. 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.
ASSEMBLY Loading nailer
CAUTION:
•Always lock the trigger and disconnect the hose before loading the nailer.
•Select nails suitable for your work. Depress the latch lever and open the
door and magazine cap.

•Lift and turn the coil support plate to set it to the correct step. When
loading 57 or 65 mm long nails, use the bottom step. When loading 45 or
50 mm long nails, use the middle step. When loading 32 or 38 mm long
nails, use the top step. 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.
•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. Close the
magazine cap and door after checking to see that the nail coil is set
properly in the magazine.
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 CAUTION:
•Make sure all safety systems are in working order before 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 work-
piece.
•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.
CAUTION:
•However when the tool is set to the "Intermittent Nailing" mode, 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.
•For No. 1 method, set the change lever to the “Intermittent Nailing”
position. For No. 2 method, set the change lever to the “Continuous
Nailing”position. After using the change lever to change the nailing
method, always make sure that the change lever is properly set to the
position for the desired nailing method.
CAUTION:
•Operating the tool without nails shortens the life of the tool and should be
avoided.
Anti exhaust
•Air exhaust direction can be changed easily by rotaiting the exhaust
cover. Change it when necessary.
