General safety
1.
Do not permit those uninstructed to use the tool.
2. No horseplay. Respect the tool as a working
implement.
3. Do not operate when under the inuence of
alcohol, drugs or the like.
4. Never alter the tool.

3ENGLISH
Personal protective equipments
1. Always wear safety glasses to protect your
eyes from dust or fastener injury.
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.
For Australia and New Zealand only
Always wear safety glasses and face shield to
protect your eyes from dust or fastener injury.
Thesafetyglassesandthefaceshieldshould
conformwiththerequirementsofAS/NZS1336.
2. 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.
Work area safety
1. Keep work area clean and well lit.Clutteredor
dark areas invite accidents.
2. Do not operate the tool in explosive atmo-
spheres, such as in the presence of ammable
liquids, gases or dust. Operating the tool can
create sparks which may ignite the dust or fumes.
3. Keep children and bystanders away while
operating the tool. Distractions can cause you to
lose control.
4. Illuminate the work area sufciently.
5.
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.
Safety devices
1. 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 contact
arm is pressed against the wood. It must work only
whenbothactionsareperformed.Testforpossible
faulty operation with fasteners unloaded and the
pusher in fully pulled position.
2. Do not play with the contact element: it pre-
vents 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.
3. Do not attempt to keep the contact element
depressed with tape or wire. Death or serious
injurymayoccur.
4. Always check contact element as instructed
in this manual. Fasteners may be driven acci-
dentally if the safety mechanism is not working
correctly.
Loading fasteners
1. Do not load the tool with fasteners when any
one of the operating controls is activated.
2. Use only fasteners specied in this manual.
Theuseofanyotherfastenersmaycausemal-
function of the tool.
Power source
1. Never connect the tool to compressed air line
where the air pressure can exceed the suitable
air pressure range of the tool, specied in the
"SPECIFICATIONS" table, by 10%. Make sure
that the pressure supplied by the compressed air
system does not exceed the suitable air pressure
range of the tool. Set the air pressure initially to
the lower value of the suitable air pressure range.
2. When using the tool operated by compressed
air, particular attention must be paid to avoid
exceeding the maximum allowable pressure.
3. Operate the tool at the lowest pressure
required for the application, in order to prevent
unnecessarily high noise levels, increased
wear and resulting failures.
4. Never use the tool with other than compressed
air.Ifbottledgas(carbondioxide,oxygen,
nitrogen,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.
5. Always disconnect the air hose and remove all
of the fasteners:
— when unattended;
— before performing any maintenance or
repair;
— beforecleaningajam;
— before moving the tool to a new location.
6. Use only pneumatic tool oil specied in this
manual.
Operational safety
1. Always check the tool for its overall condition
and loose screws before operation. Tighten as
required.
2. 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.
3. Stop the operation immediately if you notice
something wrong or out of the ordinary with
the tool. An improperly functioning tool must not
be used.
4. Do not point the ejection port at anyone in the
vicinity. Keep hands and feet away from the
ejection port area.
5. Always assume that the tool contains
fasteners.
6. Never point the tool toward yourself or anyone
whether it contains fasteners or not.
7. Do not rush the job or force the tool. Handle
the tool carefully.

4ENGLISH
8. Do not activate the tool unless the tool is
placed rmly against the workpiece.
9. Never hold or carry the tool with a nger on the
trigger or hand it to someone in this condition.
Accidentalringcancauseseriousinjury.
10. Never use fastener driving tools marked with
the symbol "Do not use on scaffoldings, lad-
ders" for specic 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;
— ttingtransportationsafetysystemse.g.on
vehicles and wagons.
11. Check walls, ceilings, oors, roong and
the like carefully to avoid possible electrical
shock, gas leakage, explosions, etc. caused by
striking live wires, conduits or gas pipes.
12. Do not use the tool for fastening electrical
cables. It is not designed for electric cable instal-
lation and may damage the insulation of electric
cablestherebycausingelectricshockorre
hazards.
13. 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.
14. On rooftops and other high locations, drive
fasteners as you move forward. It is easy to lose
your footing if you drive fasteners while inching
backward. When driving fasteners against perpen-
dicularsurface,workfromthetoptothebottom.
You can perform driving operations with less
fatigue by doing so.
15. A fastener will be bent or the tool can become
jammed if you mistakenly drive fastener on
top of another fastener or strike a knot in the
wood. The fastener may be thrown and hit
someone, or the tool itself can react danger-
ously. Place the fasteners with care.
16. Do not leave the loaded tool or the air com-
pressor 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.
17. Never attempt to drive fasteners from both the
inside and outside at the same time. Fasteners
mayripthroughand/oryoff,presentingagrave
danger.
Service
1. Perform cleaning and maintenance right after
nishing 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.
2. Ask Makita authorized service center for peri-
odical inspection of the tool.

Theaircompressormustcomplywiththerequirements
ofEN60335-2-34.
Select a compressor that has ample pressure and air
outputtoassurecost-efcientoperation.Thegraph
showstherelationbetweennailingfrequency,applica-
ble 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
1.77MPa(17.7bar),acompressorwithanairoutput
over100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
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.
Use a high pressure resistant air hose.
Use an air hose as large and as short as possible to
assurecontinuous,efcientnailingoperation.
