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.

trol depressed.
Sparkssometimesfly 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 areashould besufficiently illuminatedtoassure
safe operations.
The area should be clear and litter- free.
Be espe-
cially carefultomaintain good footing and 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 mustbecomplied
with by keepingnoiselevels
within prescribed limits. In certain cases, shutters
should be used to contain noise.
Do nottamper with the toolor attempt touse it for
other than nailing. Do not play with the contact
element;
it preventsaccidentaldischarge, 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.
Operatethe tool within the specified air pressureof
4.0 - 8.5 kgf/cm*G (60 - 120 PSIG) for safety
and longertoollife.
Do not exceedthe recommended
max. operating pressure of
8.5 kgf/cm’G (120
PSIG). Thetool should notbeconnected toasource
whose pressure potentially exceeds
14.0 kgf/cm’G
(200 PSIG).
Never usethe tool with other than compressed air.
If high-pressuregas (carbondioxide, oxygen, nitro-
gen, hydrogen, propane, acetylene, etc.) is used as
a power 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 notoperate if only
the trigger is pulled or if only the contact element
ispressedagainstthe wood.
It must work only when
bothactions are performed. Test for possiblefaulty
operation
with nails unloaded and with the pusher
locked at fully pulledposition. (Seepage
11 for the
method of locking the pusher.)
*Check walls, ceilings, floors, roofing and the like
carefully to avoid possible electrical shock, gas
leakage, explosions, etc. caused by striking lives

.Make sure no one is nearby before nailing. Never
attempt to nail from boththe inside and outside at
the sametime. Nails may ripthrough and/or fly off,
presenting a grave danger.
Watch your footing and maintainyour 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 canperformnailingoperationswithless
fatigue by doing
so.
A nail will be bent or the tool can becomejammed
ifyou mistakenly nailon top of another nailor 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.

inside the tool that can be dangerous if a crack is
causedby rough handling (droppingor striking).
Do
not attempt to carve or engrave on the tool.
Stop nailing operations immediately if you notice

TOOL INSTALLATION INSTRUCTIONS AND USE
Lubrication
To insure maximum performance, install an air set (oiler,
regulator, air filter) as close as possibletothe 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 shouldbedone beforeand after use. For proper
lubrication, the tool must be fired a couple of times after
pneumatic tool oil is introduced.
