SAFETY TOOL USE INSTRUCTIONS
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
carefully before using the tool.
Wear light but not loose clothing. Sleeves should be
buttoned or rolled up. No necktie should be worn.
*Always wear safety glasses to protect your eyes
from dust or nail injury. The safety glasses should
conform with the requirements of ANSI 287. 1 1979. Also wear hearing protection to protect your
ears against exhaust noise.
WARN ING :
It is an employer's responsibility t o enforce the use
of safety eye protection equipment by the tool
operators and by other persons in the immediate
working area.
*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:
I
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.Never depress the operating control unless the
nosepiece of the tool is directed toward the
workpiece.
4. Respect the tool as a working implement.
5. No horseplay.
6. Do not transport the tool with the operating control depressed.
7. Do not load the tool with fasteners with the work-contacting element or operating con
trol depressed.
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.
W
The area should be sufficiently illuminated t o assure
safe operations.
The area should be clear and litter- free. Be especially careful t o maintain good footing and balance.
*Only those involved in the work should be in the
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.
I
Shutter
Do not tamper with the tool or attempt t o use it for
other than nailing. Do not play with the contact arm;
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.
Trigger
Contact arm
Operate the tool within the specified air pressure of
4.2 - 8.5 kgf/cm’G (60 - 120 PSIG) for safety
and longer tool life. The tool should not be connected
to a source whose pressure potentially exceeds 14.0
kgf/cm’G (200 PSIG).
Never use the tool with other than compressed air.
If high-pressure gas (propane, acetylene, oxygen,
etc.) is used as a Dower source for this tool, the tool

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

I
Use only nails specified in this manual. The use of
any other nails may cause malfunction of the tool.
Do not permit those uninstructed t o use the tool.
.Make sure no one is nearby before nailing. Never
attempt t o 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
t o prevent danger if there is sudden jerking or
catching.
2
On rooftops and other high locations, nail as you
move forward. It is easy t o lose your footing if you
nail while inching backward. When nailing against
perpendicular surface, nail from the top t o 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.
Hold the workpiece securely. Under nailer impact,
the workpiece can fly about dangerously if not held
securely in place.
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 t o 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.
Perform cleaning and maintenance right after finishing the job. Keep the tool in tip-top condition.
Lubricate moving parts t o prevent rusting and
minimize friction related wear. 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 t o 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 t o prevent rusting. When using the tool for a long time, oil during
nailing operations.

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 8.5 mm ( 1 1/32")and a
length of less than 20 m (6.6 f t . ) is recommended
when the interval between each nailing is 0.5 seconds.
Air supply hoses shall have a minimum working pressure rating of 10.7 kgf/cm2G (150 PSIG) 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 thin air hose in relation to the nailinq frequency
may cause a decrease in the driving force
Connecting air hose
Slip the air socket of the air hose onto the air plug on
the nailer. Be sure that the air socket locks firmly into
position when installed onto the air plug.
A hose coupling must be installed on or near the tool
in such a way that the pressure reservoir will discharge
a t the time the air supply coupling is disconnected,

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.
