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 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
operatinglsafety instructions.
*An improperly functioning tool must not be used.
Sparks sometimesfly when the tool is used. Do not
usethe
tool near volatile, flammable materials such
as gasoline, thinner, paint, gas, adhesives, etc.; they
will ignite and explode, causing serious injury.
The area should besufficiently illuminatedtoassure
safe operations.
The area should be clear and litter- free. Be espe-
cially careful to maintain goodfootingand balance.

*Only those involved in the work should be in the
vicinity. Children especially must be kept away at
all times.
There may be local regulations concerning noise
which must becomplied
with by keepingnoiselevels
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.
Operatethe tool within the specified air pressureof
4.5 - 8.5 kgf/cm’G (65 - 120 PSIG) for safety
and longertool life.
Do not exceedthe recommended
max. operating pressure
of 8.5 kgf/cm’G (120
PSIG).Thetool should notbe connected toa source
whose pressure potentially exceeds
14.0 kgf/cm’G
(200 PSIG).

Never usethe tool with other than compressed air.
If bottled gas (carbon dioxide, oxgen, nitrogen,
hydrogen, air, etc.) or combustible gas (hydrogen,
propane, acetylene, etc.) isused as a powersource
for this tool, the tool will explode and cause serious
injury.
*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 element
is pressedagainstthe wood.
It mustwork only when
bothactions are performed. Test for possible faulty
operation with nails unloaded.

Make sure no one is nearby before nailing. Never
attempt to nail from both the inside and outside at
thesametime. Nails may ripthrough and/or fly off,
presenting a grave danger.
Watch your footing andmaintain four 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 performnailing operations
with less
fatigue by doing
so.
A nail will be bent or the tool can becomejammed
if you mistakenly nailontopof another nailor strike
a knot
in the wood. The nail may bethrown 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 pressurefor alongtime out
in the sun. Be sure
that dust, sand, chips and foreign matter
will not
enter the tool
in the placewhere you leave it setting.
*Do not point the ejection port at anyone in the
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 (droppingor striking). Do
not attempt to carve or engrave on the tool.
8

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:
1. When unattended.
2. Before performing any maintenance or repair.
3. Before cleaning a jam.
4. Before moving the tool to a new location.
Perform cleaningand maintenance right after finish-
ing the job. Keep the tool
in tip-top condition.
Lubricate moving parts to prevent rusting and
minimizefriction relatedwear. Wipe off all dust from
the parts.
When notoperating the tool, always lockthe trigger
by turning the change lever to the LOCK position.

TOOL INSTALLATION INSTRUCTIONS AND USE
Selecting compressor
The air compressor must comply with the requirements of
Selecta compressorthat hasample pressureandair output
to assure cost-efficient operation. The graph shows the
relationbetweennailingfrequency, applicablepressureand
compressor air output. Thus, for example, if nailing takes
place at a rate of approximately
40 times per minute at a
compression of
5 kgf/cm*G (70 PSIG), a compressor with
an air output over
2 ft3/minute is required. Pressure
regulators must be used to limit air pressure to the rated
pressureof thetoolwhere airsupply pressureexceedsthe
tool’s ratedpressure.Failure
to do so mayresult inserious
injury to tool operator or persons in the vicinity.
ANSI B19.3 - 1981.
Selecting air hose
Usean air hoseas large and asshort as possibleto assure
continuous,efficientnailingoperation.With anair pressure
of
5 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 hosesshall have a
minimum working pressure rating of
10.7 kgf/cm*G (150
PSIG) or 150 percent of the maximum pressure produced
in the system whichever is higher.
Nailing frequency (timeslmin )
CAUTION:
Lowairoutput of thecompressor,or a longor smallerdiameterair hoseinrelationtothe nailingfrequency
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.
Whenan air set is not used,oilthe toolwith pneumatictool
oil by placing
2 (two) or 3 (three)drops into the air fitting.
This should bedone beforeand after use. For proper lubri-
cation,the tool must befired a couple of times after pneu-
matic tool oil is introduced.

Nose adapter
CAUTION :
Always lock the trigger and disconnect the hose before installing or removing the nose adapter.
When nailingworkpieces with easily-marred surfaces, use
the noseadapter. It isfactory installedat the rearof the tool.
Attach the noseadapter to the contactarm(see right). When
not in use, store the nose adapter at the rear of the tool to
keep it from being lost.

Loading nailer
CAUTION:
Always lock the trigger and disconnect the hose before loading the nailer.
Select nailssuitablefor your work. Depressthe latchlever
and open the door and magazine cap.
Lift and turn the coil support plate to set it to the correct
step. When loading
57 or 65 mm (2-1/4”, 2-1/2”) long nails,
use the bottom step. When loading 45 or
50 mm (1-3/4”,
2”) long nails, use the middle step. When loading 32 or
38 mm(1-1/4”, 1-1/2”) long nails, usethe top step.
If thetool

To adjust the depth of nailing, turn the adjuster so that the
arrow abovetheadjuster will point
to the number indicated
on the adjuster. The depth of nailing is the deepest when
the arrow points
to the number 1. Itwill become shallower
as the arrow points
to higher number. The depth can be
changed inapprox.
1.0 mm (1/32”) incrementsper gradua-
tion.
If nailscannot be driven deep enough even when the
arrow points
to the number 1, increase the air pressure. If
nailsare driven too deepeven when the arrow points to the
number
9, decreasethe air pressure. Generally speaking,
the
tool service lifewill be longerwhen the tool is usedwith
lower air pressure and the adjuster set
to a lower number.
Connecting air hose
Lockthe trigger. Slipthe air socket of the air hoseontothe
