IMPORTANT SAFETY INSTRUCTIONS
USB087-1
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.
1. For personal safety and proper operation
and maintenance of the tool, read this
instruction manual carefully before using
the tool.
4. 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.
5. General Tool Handling Guidelines:
2. Always wear safety glasses to protect
your eyes from dust or nail injury. The
safety glasses should conform with the
requirements of ANSI Z87.1.
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.
(1) Always assume that the tool contains
fasteners.
3. 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.
(5) No horseplay.
2
(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.
(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.
6. An improperly functioning tool must not
be used.
7. 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.
8. 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.
9. Only those involved in the work should be
in the vicinity. Children especially must be
kept away at all times.
10. 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.
11. 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.
12. Operate the tool within the specified air
pressure on the tool label for safety and
longer tool life. Do not exceed the recommended max. operating pressure. The
tool should not be connected to a source
whose pressure potentially exceeds 14.0
kgf/cm2G (200 PSIG).
13. 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.
14. Always check the tool for its overall condition and loose screws before operation.
Tighten as required.
15. 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
and the contact element in fully pulled
position.
16. 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.
17. Use only nails specified in this manual.
The use of any other nails may cause malfunction of the tool.
18. Do not permit those uninstructed to use
the tool.
19. 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.
20. 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.
21. 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
3
surface, nail from the top to the bottom.
You can perform nailing operations with
less fatigue by doing so.
22. 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.
23. 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.
24. Do not point the ejection port at anyone in
the vicinity. Keep hands and feet away
from the ejection port area.
25. 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.
26. 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.
27. Stop nailing operations immediately if you
notice something wrong or out of the ordinary with the tool.
28. 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.
29. Perform cleaning and maintenance right
after finishing the job. Keep the tool in tiptop condition. Lubricate moving parts to
prevent rusting and minimize frictionrelated wear. Wipe off all dust from the
parts.
30. Do not modify tool without authorization
from Makita.
31. Do not attempt to keep the trigger or contact element depressed with tape or wire.
Death or serious injury may occur.
32. Always check contact element as
instructed in this manual. Nails may be
driven accidentally if the safety mechanism is not working correctly.
33. Ask Makita's Authorized service centers
for periodical inspection of the tool.
34. To maintain product SAFETY and RELIABILITY, maintenance and repairs should
be performed by Makita Authorized or
Factory Service Centers, always using
Makita replacement parts.

Nailing frequency(times/min.)
004294
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 30 times per minute at a compression of 6.0 kgf/
cm2G (85 PSIG), a compressor with an air output over 1 ft3/
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 5.0 kgf/cm2G (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 10.7 kgf/cm2G (150 PSIG) or 150 percent of the maximum pressure produced in the system
whichever is higher.
•
004295
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.
6
005624
1
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
To adjust the depth of nailing, press the knob toward the
nose tip and 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. 0.8
mm (1/32”) 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.

MAINTENANCE
Avoid storing nails in a very humid or hot place or place
exposed to direct sunlight.
CAUTION:
• Always disconnect the air hose from the tool before
attempting to perform inspection or maintenance.
Cleaning and removal of tar and dirt
Adhesion of tar and dirt to areas around the contact element
will prevent smooth movement of the contact element (safety
mechanism), causing accidental discharge. Periodically
clean the areas around the contact element. Cleaning can be
performed easily if the contact element is removed. So proceed as follows.
005635
Turn the adjuster so that the arrow will point between numbers 1 and 5.
Hold the contact element and press the knob toward the
nose tip. While keeping the knob pressed, turn it counterclockwise fully. Then release the knob and remove the contact element from the driver guide. If you have difficulty
removing the contact element because it is caught by the
safety cover, open the magazine cap.
005636
Use a solvent such as kerosene, #2 fuel oil or diesel fuel.
Immerse only the contact element and the areas around the
ejection port in solvent and remove tar and dirt with brush.
Always wear waterproof gloves to protect your hands. Never
immerse the housing, magazine, etc. in solvent. Malfunction
of the tool may result. Always dispose of the solvent used in
a safe and prudent manner and in compliance with all local
and national code requirement.

Dry off the tool before use. Any oil film left after cleanup will
accelerate the tar buildup, and the tool will require more frequent recleaning. After drying off the tool, oil the moving
parts to prevent rusting and to assure good lubrication and
11
operation or moving parts. Install the contact element on the
driver guide. Press the knob toward the nose tip and turn the
knob clockwise to secure.
WARNING:
• Never use gasoline or other similar highly volatile liquids
for cleaning. Vapors of such liquids may enter the tool
and could be ignited by sparks produced during nailing
and cause an explosion.
