IMPORTANT SAFETY INSTRUCTIONS
ENB067-2
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.
•
Only those involved in the work should be in the
vicinity. Children especially must be kept away
at all times.
•
Always wear safety glasses to protect your eyes
from dust or nail injury.
•
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 inoperable, disconnected, altered, or not working properly.
•
Operate the tool within the specified air pressure of 0.44 - 0.83 MPa (4.4 - 8.3 bar) for safety
and longer tool life. Do not exceed the recommended 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 pressure (see SPECIFICATIONS).
•
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.
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 fasteners.
2.
Do not point the tool toward yourself or anyone 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 activated.
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.
Always check the tool for its overall condition
and loose screws before operation. Tighten as
required.
•
•
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.
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 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.
3
•
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.
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.
•
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:
•
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:
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 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
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.
•
Do not modify tool without authorization from
Makita.
•
Ask Makita’s Authorized service centers for periodical inspection of the tool.

by Makita Authorized Service Centers, always
using Makita replacement parts.
•
Use only pneumatic tool oil specified in this
manual.
•
Never connect tool to compressed air line where
the maximum allowable pressure of tool cannot
be exceeded by 10 %. 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 pressure.
•
Do not attempt to keep the trigger or contact
element depressed with tape or wire. Death or
serious injury may occur.
•
Always check contact element as instructed in
this manual. Nails may be driven accidentally if
the safety mechanism is not working correctly.

Selecting compressor
The air compressor must comply with the requirements of EN60335-2-34.
Select a compressor that has ample pressure and air output to assure costefficient 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(4.9bar), an air hose
with an internal diameter of over 8.5 mm and a length of less than 20 m (6.6 ft.)
is recommended when the interval between each nailing is 0.5 seconds.
•
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
005368
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.
005461
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.

Adjusting depth of nailing
005467
1
1. Adjuster

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.
