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.

⅜ If merely pulling the trigger causes operating

sound of drive bit movement occur, the power

tool is faulty.

⅜ 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

followings.

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 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. 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.

14. 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.

15. 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.

16. 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.

17. 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.

18. Do not use the power tool on scaffoldings, ladders.

The power tool shall not be used for specific

application 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

vehicles and wagons

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. 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.
