IMPORTANT SAFETY
INSTRUCTIONS
USB086-1
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.
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.
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.
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:
(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 actuate 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.
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
2
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
2
kgf/cm
G (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. Make sure that the trigger is locked when the
change lever is set to the LOCK position.
17. 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.
18. Use only nails specified in this manual. The use
of any other nails may cause malfunction of the
tool.
19. Do not permit those uninstructed to use the tool.
20. 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.
21. 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.
22. 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.
23. 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.
24. 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.
25. Do not point the ejection port at anyone in the
vicinity. Keep hands and feet away from the ejection port area.
26. 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.
27. 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.
28. Stop nailing operations immediately if you
notice something wrong or out of the ordinary
with the tool.
29. 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.
30. 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.
31. When not operating the tool, always lock the trigger by turning the change lever to the LOCK
position.
32. Do not modify tool without authorization from
Makita.
33. Do not attempt to keep the trigger or contact element depressed with tape or wire. Death or serious injury may occur.
34. Always check contact element as instructed in
this manual. Nails may be driven accidentally if
the safety mechanism is not working correctly.
35. Ask Makita's Authorized service centers for periodical inspection of the tool.
36. To maintain product SAFETY and RELIABILITY,
maintenance and repairs should be performed
by Makita Authorized or Factory Service Centers,
always using Makita replacement parts.

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/cm
internal diameter of over 8.5 mm (5/16”) and a length of
less than 20 m (6.6 ft.) is recommended when the inter-
004294

G (70 PSIG), an air hose with an
val between each nailing is 0.5 seconds. Air supply
hoses shall have a minimum working pressure rating of
10.7 kgf/cm
2
G (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
smaller diameter air hose in relation to the nailing
frequency may cause a decrease in the driving
capability of the tool.

Nailing frequency (times/min)
The air compressor must comply with the requirements
of ANSI B19.3.
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 40 times per minute at a compression of
6.0 kgf/cm
over 3 ft
2
G (85 PSIG), a compressor with an air output
3
/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.
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
ASSEMBLY
CAUTION:
• Always lock the trigger and disconnect the hose
before adjusting or checking function on the tool.
A
1
To adjust the depth of nailing, turn the adjuster. The
depth of nailing is the deepest when the adjuster is
turned fully in the A direction shown in the figure. It will
become shallower as the adjuster is turned in the B
direction. If nails cannot be driven deep enough even
when the adjuster is turned fully in the A direction,
increase the air pressure. If nails are driven too deep
even when the adjuster is turned fully in the B direction,
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 depth of nail
driving.

2. Pull the trigger first and then place the contact ele-
ment against the workpiece.
• 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
position.
For No. 2 method, set the change lever to the
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.
