use the power tool until it has been inspected and
repaired.
If merely pulling the trigger causes operating
sound of drive bit movement occur, the power
tool is faulty.
If merely depressing the push lever against the
material to be nailed causes the sound of drive
bit movement to occur, the power tool is faulty.
Furthermore, with regard to the push lever, please
note that it must never be modified or removed.
10. Use specified nails only.
Never use nails other than those specified and de-
scribed in this handling instructions.
11. Be careful when connecting the hose.
When connecting the hose and loading nails in order
not to fire the tool by mistake, make sure of the
following.
Do not touch the trigger.
Do not allow the firing head to contact with any
surface.
Keep the firing head down.
Strictly observe the above instructions, and al-
ways make sure that no part of the body, hands
or legs is ever in front of the nail outlet.
12. Do not carelessly place your finger on the trigger.
Do not place your finger on the trigger except actu-
ally nailing. If you carry this tool or hand it to
someone while having your finger on the trigger,
you may inadvertently firing a nail and thus cause an
accident.
13. Completely Close the nail guide and do not open it
during operation.
If nailing is attempted when the nail guide is open,
nails will not be driven into the timber, and there is
a risk of dangerous discharge.
14. Press the nail outlet firmly against the material to be
nailed.
When driving in nails, press the nail outlet firmly
against the material to be nailed. If the outlet is not
applied properly, the nails may rebound.
15. Keep hands and feet away from the firing head
when using.
It is very dangerous for a nail to hit the hands or feet
by mistake.
16. Beware of the tool's kickback
Do not approach the top of the tool with your head
etc. during operation. This is dangerous because the
tool may recoil violently if the nail currently being
driven in comes into contact with a previous nail or
a knot in the wood.
17. Take care when nailing thin boards or the corners of
wood.
When nailing thin boards, the nails may pass right
through, as may also be the case when nailing the
corners of wood due to deviation of the nails. In such

cases, always make sure that there is no one (and
nobody's hands or feet; etc.) behind the thin board
or next to the wood you are going to nail.
18. Simultaneous nailing on both sides of the same
wall is dangerous
Under no circumstances should nailing be per-
formed on both sides of a wall at the same time.
This would be very dangerous since the nails might
pass through the wall and thus cause injuries.
19. Do not use the power tool on scaffoldings, ladders.
The power tool shall not be used for specific appli-
cation for example:
– when changing one driving location to another
involves the use of scafforldings, 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
20. Do not disconnect the hose with your finger on the
trigger.
If you disconnect the hose with your finger on the
trigger, the next time the hose is connected, there
is a danger that the power tool will fire a nail
spontaneously, or operate incorrectly.
21. Disconnect the hose and take out any nails left in
the magazine after use.
Disconnect tool from compressed air before doing
tool maintenance, cleaning a jammed fastener,
leaving work area, moving tool to another location,
or after use. It is very dangerous for a nail to be fired
by mistake.
22. When removing a nail which has become stuck,
make sure to first of all disconnect the hose and
release compressed air.
When removing a nail which has become stuck in
the nail outlet, first of all make sure to disconnect
the hose and release compressed air inside the
power tool.
Accidental firing of the nail could be very danger-
ous.
23. To avoid hazards caused by falling nails, never
open the magazine with the nail outlet facing
downward while loading nails.
24. A female plug (air socket) should not be used in the
body.
If a female plug is installed in the body, the com-
pressed air sometimes can not be drawn when the
hose is disconnected so avoid this.
The tool and air supply hose must have a hose
coupling such that all pressure is removed from the
tool when the coupling joint is disconnected.
25. Do not remove the dust cover
Never operate with the dust cover removed in order
to avoid the danger of breakage of the wire or
plastic retaining the nails or missed-fired nails fly-
ing about.
