GeneralTool 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 activate 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 isactivated.
8. Do not operate the tool with any power source other than that specified in the tool
operatingkafety instructions.
*An improperly functioning tool must not be used.

all times.
There may be local regulations concerning noise

Never usethe tool with other than compressedair.
If bottled gas (carbon dioxide, oxgen, nitrogen,
hydrogen, air, etc.) or combustible gas (hydrogen,
propane,acetylene, etc.) isusedas a power source
for thistool, the tool will explodeand causeserious
injury.

Use only nailsspecified in this manual. The use of
any other nailsmay cause malfunction of the tool.

Do not permit those uninstructed to use the tool.
.Make sure no one is nearby before nailing. Never
attempt tonailfrom boththe inside and outsideat
thesame time. Nailsmay ripthroughand/orfly off,
presentinga grave danger.
Watchyour footingandmaintainyour 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
moveforward.
It iseasy to loseyour footing if you
nail while inching backward. When nailing against
perpendicular surface, nail from the top to the
bottom. You can performnailingoperations
with less
fatigue by doing so.
A nail will be bent or the tool can becomejammed
ifyou mistakenly nailon topof another nailor strike
a knot in the wood. The nailmay bethrownand hit
someone, or the tool itself can react dangerously.
Place the nails
with care.
Do not leave the loadedtool or the air compressor
under pressurefor alongtime out
in thesun. Be sure
that dust, sand, chips and foreign matter
will not
enter thetool
in theplacewhere you leave it setting.
*Do not point the ejection port at anyone in the
vicinity. Keephandsandfeet awayfromtheejection
port area.

When the air hose is connected, do not carry the
tool
with your finger on the trigger or hand it to
someoneinthis 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 byroughhandling (dropping or striking).
Do
not attempt to 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:
1. When unattended.
2. Before performing any maintenance or repair.
3. Before cleaning a jam.
4. Before moving the tool to a new location.

TOOL INSTALLATIONINSTRUCTIONS AND USE
Selecting compressor
The air compressor mustcomply with the requirements of
Select acompressor that has ample pressureand air output
to assure cost-efficient operation. The graph shows the
relation betweennailingfrequency, applicable pressureand
compressor air output. Thus, for example, if nailingtakes
place at a rateof approximately 50times per minute at a
compression of 5 kgf/cm2G
(70 PSIG), a compressor with
an air output over 30 literdminute is required. Pressure
regulators must be used to
limit air pressure to the rated
pressure of thetool where air supply pressure exceeds the
tool's rated pressure. Failuretodo
so may result in serious
injury to tool operator or persons
in the vicinity.
ANSI 819.3
- 1981.
Selecting air hose
Usean air hoseas large and as short as possible toassure
continuous, efficient nailingoperation. Withanair pressure
of
5 kgf/cm2G (70 PSIG), an air hose with an internal
diameter
of over 6.5 mm(17/64") and a lengthof lessthan
20 m (6.6 ft.) is recommendedwhenthe intervalbetween
each nailing is 0.5 seconds. Air supply hoses shall have a
minimum working pressure rating of 10.7 kgf/cm2G(150
PSIG) or 150percent of the maximumpressure produced
in the system whichever is higher.

Nailing frequency (timesh")
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 tothe tool. Adjust
the oiler
so that one drop of oil will be provided for every
50nails.
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 bedone before andafter use. For proper
lubrication, the tool must be fired a couple of times after
pneumatic tool
oil is introduced.
