9. Before using the power tool, check the push lever.
Before using the power tool make sure to check that
the push lever and valve operate properly. Without
nails loaded into the power tool, connect the hose
and check the following. If the sound of operation
occurs this indicates a fault, so in such a case do not
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 pushing 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
described in these 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 always
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 when
actually nailing. If you carry this tool or hand it to
someone while having your finger on the trigger,
you may inadvertently discharge 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
performed 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 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.
20. Disconnect the hose and take out any nails 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 nail to be fired by
mistake.
21. 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 dangerous.
22. To avoid hazards caused by falling nails, never
open the magazine with the device facing
downward while loading nails.
23. 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 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.
