PRECAUTIONS ON USING NAILER

1. Safe operation through correct usageThis tool was designed for driving nails into woodand similar materials. Use it for its intendedpurpose only.

2. Make sure air pressure is within the rated rangeof air pressure.Please make sure that the air pressure is withina range of 4.9 bar – 8.3 bar, and that the air whichis used is clean and dry. If the air pressure isgreater than 8.3 bar, the life of the power toolwill be shortened and dangerous conditions coulddevelop. Tools shall not be connected to pressurewhich potentially exceeds 14 bar.

3. Never operate the equipment with high-pressuregases other than compressed air.Never use carbon dioxide, oxygen or another gasfrom pressurized containers under anycircumstances.

4. Be careful of ignition and explosions.Since sparks may fly during nailing, it is dangerousto use this tool near lacquer, paint, benzine, thinner,gasoline, gas, adhesives and similar inflammablesubstances as they may ignite or explode. Underno circumstances should this tool therefore beused in the vicinity of such inflammable material.

5. Always wear eye protection (protective goggles).When operating the power tool, always wear eyeprotection, and ensure that surrounding peoplewear eye protection too.The possibility of fragments of the nails that werenot properly hit entering the eye is a threat tosight. Eye protection can be bought at anyhardware store. Always wear eye protection whileoperating this tool. Use either eye protection ora wide vision mask over prescription glasses.Employers should always enforce the use of eyeprotection equipment.

6. Protect your ears and head.When engaged in nailing work please wear earmufflers and head protection. Also, depending oncondition, ensure that surrounding people alsowear ear mufflers and head protection.

7. Pay attention to those working close to you.It would be very dangerous if nails that were notproperly driven in should hit other people.Therefore, always pay attention to the safety ofthe people around you when using this tool.Always make sure that nobody’s body, hands orfeet are close to the nail outlet.

8. Never point the nail outlet towards people.Always assume the tool contains fasteners.If the nail outlet is pointed towards people, seriousaccidents may be caused if you mistakenlydischarge the tool. When connecting anddisconnecting the hose, during nail loading orsimilar operations, be sure the nail outlet is notpointed towards anyone (including yourself). Evenwhen no nails are loaded at all, it is dangerousto discharge the tool while pointing it at someone,so never attempt to do so. No horseplay. Respectthe tool as a working implement.

9. Before using the power tool, check the pushlever.Before using the power tool make sure to checkthat the push lever and valve operate properly.Without nails loaded into the power tool, connectthe hose and check the following. If the soundof operation occurs this indicates a fault, so in

such a case do not use the power tool until ithas been inspected and repaired.� If merely pulling the trigger causes operating

sound of drive bit movement occur, the powertool is faulty.

� If merely pushing the push lever against thematerial to be nailed causes the sound of drivebit movement to occur, the power tool is faulty.Furthermore, with regard to the push lever,please note that it must never be modified orremoved.

10. Use specified nails only.Never use nails other than those specified anddescribed in these instructions.

11. Be careful when connecting the hose.When connecting the hose and loading nails inorder not to fire the tool by mistake, make sureof the followings.� 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 alwaysmake sure that no part of the body, hands orlegs 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 exceptwhen actually nailing. If you carry this tool orhand it to someone while having your finger onthe trigger, you may inadvertently discharge a nailand thus cause an accident.

13. Press the nail outlet firmly against the materialto be nailed.When driving in nails, press the nail outlet firmlyagainst the material to be nailed. If the outlet isnot applied properly, the nails may rebound.

14. Keep hands and feet away from the firing headwhen using.It is very dangerous for a nail to hit the handsor feet by mistake.

15. Beware of the tool’s kickbackDo not approach the top of the tool with yourhead etc. during operation. This is dangerousbecause the tool may recoil violently if the nailcurrently being driven in comes into contact witha previous nail or a knot in the wood.

16. Take care when nailing thin boards or the cornersof wood.When nailing thin boards, the nails may pass rightthrough, as may also be the case when nailingthe corners of wood due to deviation of the nails.In such cases, always make sure that there is noone (and nobody’s hands or feet; etc.) behind thethin board or next to the wood you are going tonail.

17. Simultaneous nailing on both sides of the samewall is dangerousUnder no circumstances should nailing beperformed on both sides of a wall at the sametime. This would be very dangerous since thenails might pass through the wall and thus causeinjuries.

18. Do not use the power tool on scaffoldings, ladders.The power tool shall not be used for specificapplication for example:– when changing one driving location to another

involves the use of scafforldings, stairs, laddersor ladder alike constructions, e.g. roof laths,

– closing boxes or crates,

– fitting transportation safety systems e.g. onvehicles and wagons

19. Do not disconnect the hose with your finger onthe trigger.If you disconnect the hose with your finger onthe trigger, the next time the hose is connected,there is a danger that the power tool will fire anail spontaneously, or operate incorrectly.

20. Disconnect the hose and take out any nails leftin the magazine after use.Disconnect tool from air before doing toolmaintenance, cleaning a jammed fastener, leavingwork area, moving tool to another location, orafter use. It is very dangerous for a nail to be firedby mistake.

21. When removing a nail which has become stuck,make sure to first of all disconnect the hose andrelease compressed air.When removing a nail which has become stuckin the nail outlet, first of all make sure to disconnectthe hose and release compressed air inside thepower tool.Accidental firing of the nail could be verydangerous.

22. A female plug (air socket) should not be used inthe body.If a female plug is installed in the body, thecompressed air sometimes can not be drawn whenthe hose is disconnected so avoid this.The tool and air supply hose must have a hosecoupling such that all pressure is removed fromthe tool when the coupling joint is disconnected.

23. When attaching and detaching the nose cap,disconnect the hose.When attaching the accessory nose cap to the tipof the push lever and when detaching it, makesure to disconnect the hose beforehand. It is verydangerous for a nail to be fired by mistake.
