English
○ If merely pulling the trigger causes operating sound of
drive bit movement occur, the power tool is faulty.
○ If merely pushing the push lever against the material
into which a screw is to be driven 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 modifi ed or removed.
10. Use specifi ed screws only.
Never use screws other than those specifi ed and
described in these instructions.
11. Be careful when connecting the hose.
When connecting the hose and loading screws in order
not to fi re the tool by mistake, make sure of the following.
○ Do not touch the trigger.
○ Do not allow the fi ring head to contact with any
surface.
○ Keep the fi ring head down.
Strictly observe the above instructions, and always
make sure that no part of the body, hands or legs is
ever in front of the screw outlet.
12. Do not carelessly place your fi nger on the trigger.
Do not place your fi nger on the trigger except when
actually driving screw. If you carry this tool or hand it
to someone while having your fi nger on the trigger, you
may inadvertently discharge a screw and thus cause an
accident.
13. Completely Close the screw guide and do not open
it during operation.
If driving screw is attempted when the screw guide is
open, screws will not be driven into the timber, and there
is a risk of dangerous discharge.
14. Press the screw outlet fi rmly against the material to
be drived a screw.
When driving in screws, press the screw outlet fi rmly
against the material into which a screw is to be driven.
If the outlet is not applied properly, the screws may
rebound.
15. Keep hands and feet away from the fi ring head when
using.
It is very dangerous for a screw 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 screw currently being driven in
comes into contact with a previous screw or a knot in the
wood.
17. Take care when driving screw thin boards or the
corners of wood.
When driving screw thin boards, the screws may pass
right through, as may also be the case when driving
screw the corners of wood due to deviation of the screws.
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 screw.
18. Simultaneous driving screw on both sides of the
same wall is dangerous
Under no circumstances should driving screw be
performed on both sides of a wall at the same time. This
would be very dangerous since the screws might pass
through the wall and thus cause injuries.

19. Do not use the power tool on scaff oldings, ladders.
The power tool shall not be used for specifi c application
for example:
– when changing one driving location to another
involves the use of scaff orldings, stairs, ladders or
ladder alike constructions, e.g. roof laths,
– closing boxes or crates,
– fi tting transportation safety systems e.g. on vehicles
and wagons
20. Do not disconnect the hose with your fi nger on the
trigger.
If you disconnect the hose with your fi nger on the trigger,
the next time the hose is connected, there is a danger
that the power tool will fi re a screw spontaneously, or
operate incorrectly.
21. Disconnect the hose and take out any screws left in
the magazine after use.
Disconnect tool from 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 screw to be fi red by mistake.
22. When removing a screw which has become stuck,
make sure to fi rst of all disconnect the hose and
release compressed air.
When removing a screw which has become stuck in the
screw outlet, fi rst of all make sure to disconnect the hose
and release compressed air inside the power tool.
Accidental fi ring of the screw could be very dangerous.
23. To avoid hazards caused by falling screws, never
open the magazine with the device facing downward
while loading screws.
24. A female plug (air socket) should not be used in the
body.
If a female plug is installed in the body, the compressed
air sometimes cannot 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 screws or missed-fi red screws fl ying about.
26. Disconnect the air hose before operating the nose
switch lever.
Be sure to disconnect the air hose before operating
the nose switch lever. Otherwise, you run the risk of
accidentally fi ring screws.
27. When attaching and detaching the nose cap,
disconnect the hose.
When attaching the accessory nose cap to the tip of
the push lever and when detaching it, make sure to
disconnect the hose beforehand. It is very dangerous for
a screw to be fi red by mistake.
28. Use a compressor and an air hose intended for
high-pressure nailers.
This screw driver is designed to operate with air pressure
higher than that for general nailers. Therefore, use a
compressor and an air hose intended for use with a high-
pressure nailer. The main unit of this screw driver, its air
plug, and the air socket used to connect the compressor
and air hose are exclusively designed for use with high-
pressure parts, and cannot be connected to standard-
pressure parts. Do not modify the air plug and air socket.
Using other parts may result in an accident.
