• 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.

• 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.

• 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 be complied with by keeping noise lev-

els within prescribed limits. In certain cases, shut-

ters 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 controls is inop-

erable, disconnected, altered, or not working prop-

erly.

• Operate the tool within the specified air pressure of

0.44 – 0.83 MPa (4.4 – 8.3 bar) for safety and longer

tool life. Do not exceed the recommended max.

operating pressure of 0.83 MPa (8.3 bar). The tool

should not be connected to a source whose pres-

sure potentially exceeds 1.37 MPa (13.7 bar).

• Make sure that the pressure supplied by the com-

pressed air system does not exceed the maximum

allowable pressure of the fastener driving tool. Set

the air pressure initially to the lower value of the

recommended allowable pressure (see SPECIFICA-

TIONS).

• 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.

• 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 arm is

pressed against the wood. It must work only when

both actions are performed. Test for possible faulty

operation with staples unloaded.

• 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.

• Use only staples specified in this manual. The use

of any other staples may cause malfunction of the

tool.

• Never use fastener driving tools marked with the

symbol “Do not use on scaffoldings, ladders” for

specific application for example:

- when changing one driving location to another

involves the use of scaffoldings, stairs, ladders,

or ladder alike constructions, e.g. roof laths;

- closing boxes or crates;

- fitting transportation safety systems e.g. on vehi-

cles and wagons.

• Do not permit those uninstructed to use the tool.

• Make sure no one is nearby before stapling. Never

attempt to staple from both the inside and outside

at the same time. Staples may rip through and/or fly

off, presenting a grave danger.

• 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.

• On rooftops and other high locations, staple as you

move forward. It is easy to lose your footing if you

staple while inching backward. When stapling

against perpendicular surface, staple from the top

to the bottom. You can perform stapling operations

with less fatigue by doing so.

• A staple will be bent or the tool can become

jammed if you mistakenly staple on top of another

staple or strike a knot in the wood. The staple may

be thrown and hit someone, or the tool itself can

react dangerously. Place the staples with care.

• 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.

• Do not point the ejection port at anyone in the

vicinity. Keep hands and feet away from the ejec-

tion port area.

• 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 (dropping or striking).

Do not attempt to carve or engrave on the tool.

• Stop stapling 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 staples:

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 cleaning and maintenance right after fin-

ishing the job. Keep the tool in tip-top condition.

Lubricate moving parts to prevent rusting and min-

imize friction-related wear. Wipe off all dust from

the parts.

• Do not operate this tool if it does not contain a legi-

ble WARNING LABEL.
