use the power tool until it has been inspected and

repaired.

⅜ If merely pulling the trigger causes operating

sound of drive bit movement occur, the power

tool is faulty.

⅜ 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.

⅜ Do not touch the trigger.

⅜ Do not allow the firing head to contact with any

surface.

⅜ 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.
