PRECAUTIONS ON USING NAILER

1. Safe operation through correct usage

This tool was designed for driving nails into wood and similar materials. Use it for its intended purpose only.

2. Make sure air pressure is within the rated range of

air pressure. Please make sure that the air pressure is within a range of 12 bar – 23 bar (170 ~ 320 psi), and that the air which is used is clean and dry. If the air pressure is greater than 23 bar (320 psi), the life of the power tool will be shortened and dangerous conditions could develop. Tools shall not be connected to pressure which potentially exceeds 26 bar (370 psi).

3. Never operate the equipment with high-pressure

gases other than compressed air. Never use carbon dioxide, oxygen or another gas from pressurized containers under any circumstances.

4. Be careful of ignition and explosions.

Since sparks may fl y during nailing, it is dangerous to use this tool near lacquer, paint, benzine, thinner, gasoline, gas, adhesives and similar infl ammable substances as they may ignite or explode. Under no circumstances should this tool therefore be used in the vicinity of such infl ammable material.

5. Always wear eye protection (protective goggles).

When operating the power tool, always wear eye protection, and ensure that surrounding people wear eye protection too. The possibility of fragments of the wire or plastic linking the nails or nails that were not properly hit entering the eye is a threat to sight. Eye protection can be bought at any hardware store. Always wear eye protection while operating this tool. Use either eye protection or a wide vision mask over prescription glasses. Employers should always enforce the use of eye protection equipment. 0000NV90HMC.indb400000NV90HMC.indb40 2019/07/3111:33:442019/07/3111:33:4441 English

6. Protect your ears and head.

When engaged in nailing work please wear ear muffl ers and head protection. Also, depending on condition, ensure that surrounding people also wear ear muffl ers and head protection. Unprotected exposure to high noise levels can cause permanent, disabling, hearing loss and other problems such as tinnitus (ringing, buzzing, whistling or humming in the ears). Risk assessment and implementation of appropriate controls for these hazards are essential. Appropriate controls to reduce the risk may include actions such as damping materials to prevent workpieces from “ringing”. Operate and maintain the tool as recommended in these instructions, to prevent an unnecessary increase in noise levels.

7. Pay attention to those working close to you.

It would be very dangerous if nails that were not properly driven in should hit other people. Therefore, always pay attention to the safety of the people around you when using this tool. Always make sure that nobody’s body, hands or feet 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, serious accidents may be caused if you mistakenly discharge the tool. When connecting and disconnecting the hose, during nail loading or similar operations, be sure the nail outlet is not pointed towards anyone (including yourself). Even when no nails are loaded at all, it is dangerous to discharge the tool while pointing it at someone, so never attempt to do so. No horseplay. Respect the tool as a working implement.

9. Before using the power tool, check the push lever.

You may rest the tool on a level surface as shown in Fig.12. Be sure not to apply the force downward onto the tool to the extent that the push lever is engaged. 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 modifi ed or removed.

10. Use specifi ed nails only.

Never use nails other than those specifi ed and described in these instructions.

11. Do not modify the fastener driving tool.

Modifi cations may reduce the eff ectiveness of safety measures and increase the risks to the operator and/or bystander.

12. Be careful when connecting the hose.

When connecting the hose and loading nails 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 nail outlet.

13. Be careful when handling fasteners, especially

when loading and unloading, as the fasteners have sharp points which could cause injury.

14. Do not carelessly place your fi nger on the trigger.

Do not place your fi nger on the trigger except when actually nailing. If you carry this tool or hand it to someone while having your fi nger on the trigger, you may inadvertently discharge a nail and thus cause an accident.

15. 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.

16. Press the nail outlet fi rmly against the material to

be nailed. When driving in nails, press the nail outlet fi rmly against the material to be nailed. If the outlet is not applied properly, the nails may rebound.

17. Keep hands and feet away from the fi ring head

when using. It is very dangerous for a nail to hit the hands or feet by mistake.

18. During operation, debris from workpiece and

fastening/collation system may be discharged.

19. 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.

20. 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.

21. 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.

22. 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

23. 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 nail spontaneously, or operate incorrectly.

24. 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 fi red by mistake. 0000NV90HMC.indb410000NV90HMC.indb41 2019/07/3111:33:442019/07/3111:33:4442 English

25. When removing a nail which has become stuck,

make sure to fi rst of all disconnect the hose and release compressed air. When removing a nail which has become stuck in the nail outlet, fi rst of all make sure to disconnect the hose and release compressed air inside the power tool. Accidental fi ring of the nail could be very dangerous.

26. To avoid hazards caused by falling nails, never

open the magazine with the device facing downward while loading nails.

27. 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.

28. While using a tool, the operator shall adopt a

suitable but ergonomic posture. Maintain secure footing and avoid awkward or off - balanced postures.

29. If the operator experiences symptoms such as

persistent or recurring discomfort, pain, throbbing, aching, tingling, numbness, burning sensation, or stiff ness, do not ignore these warning signs. The operator shall consult a qualifi ed health professional regarding overall activities.

30. Long time continuous and repetitive work may

lead to muscular-skeletal disorders. Do not keep working with a same posture or by applying excessive force for a long time. And take some rest regularly and especially when you feel tired.

31. Slips, trips and falls are major causes of workplace

injury. Be aware of slippery surfaces caused by use of the tool and also of trip hazards caused by the airline hose.

32. Proceed with additional care in unfamiliar

surroundings. Hidden hazards may exist, such as electricity or other utility lines.

33. Make sure there are no electrical cables, gas pipes

etc. that could cause a hazard if damaged by use of the tool.

34. Risk assessment should include dust created by

the use of the tool and the potential for disturbing existing dust.

35. Direct the exhaust so as to minimize disturbance

of dust in a dust fi lled environment.

36. Where dust or exhaust hazards are created, the

priority shall be to control them at the point of emission.

37. Information to conduct a risk assessment of

these hazards and implementation of appropriate controls is essential.

38. Exposure to vibration can cause disabling damage

to the nerves and blood supply of the hands and arms.

39. Wear warm clothing when working in cold

conditions, keep your hands warm and dry.

40. If you experience numbness, tingling, pain or

whitening of the skin in your fi ngers or hands, seek medical advice from a qualifi ed occupational health professional regarding overall activities.

41. Operate and maintain the tool as recommended

in these instructions, to prevent an unnecessary increase in vibration levels.

42. Hold the tool with a light, but safe, grip because

the risk from vibration is generally greater when the grip force is higher.

43. 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-fi red nails fl ying about.

44. 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 nails.

45. 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 nail to be fi red by mistake.

46. Use a compressor and an air hose intended for

high-pressure nailers. This nailer 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 nailer, 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.

1. Check the air pressure

CAUTION Use a compressor designed for high-pressure operation. The air pressure must be constantly maintained at 12 – 23 bar (170 – 320 psi). Adjust the air pressure between 12 to 23 bar (170 – 320 psi) according to the diameters and length of nails and hardness of the wood being nailed. Pay special attention to the output pressure, capacity, and piping on the air compressor, so that air pressure does not exceed the specifi ed limit. Note that excessive pressure may aff ect overall performance, service life, and safety.

2. Lock mechanism of the trigger

This device has a lock mechanism to prevent the trigger from pulling. Set the lock lever to “Lock” position to lock the trigger in place. To drive a nail, turn the lock lever to the “Free” position. When not driving nails set the lever to the “Lock” position (Fig. 2). CAUTION Keep the trigger locked at all times except when driving nails.

(1) Be sure to lubricate this nailer at least twice a day. To lubricate, pour 10 to 15 drops of oil into the air plug before and after using this nailer. The oil applied before use lubricates this nailer; the oil applied after use prevents rust. (2) It is recommended using the recommended oil (SHELL TONNA). Other applicable oils are listed. Never mix two or more types of diff erent oils.

4. Nose Selection and Switching

This nailer allows you to switch the nail outlet between two sizes to extend the range of usable types and sizes of nails. Set the nose switch lever to select the outlet size matching the head diameter of the nail to be used as shown below (Fig. 3). Head Diameter Outlet size ø 6.0 mm – ø 7.5 mm (0.236" – 0.295") Small ø 7.5 mm – ø 8.6 mm (0.295" – 0.339") Large CAUTION Be sure to disconnect the air hose before operating the nose switch lever. NOTE Be sure to switch to the appropriate nose for the nails to be used. Selecting an inappropriate nose may cause defective nailing or sparking. It may also cause a nail jam, damage to this nailer or personal injury.

(1) Grip the nail guide and knob with fi nger. Press the knob down and swing the nail guide open. And open the magazine cover (Fig. 4). (2) Adjust the position of the nail holder according to the nail length (Fig. 5). The nail will not feed smoothly if the nail holder is not correctly adjusted (Fig. 6). a. Turn the nail holder about 90 degrees counterclockwise. b. Slide in vertical direction possible. Lift or lower the nail holder to accept diff erent length nails. 0000NV90HMC.indb430000NV90HMC.indb43 2019/07/3111:33:442019/07/3111:33:4444 English c. Adjust the plate to the nail length reference points on the magazine cover and turn the nail holder 90 degrees clockwise until you hear “click”. (3) Place the nail coil into the magazine. Uncoil enough nails to reach the driving hole (Fig. 7). When using wire collated nails Insert the fi rst nail into the driving hole and the second nail between the two pawls of the feeder. Fit the nail head in the guide slot (Fig. 8). When using plastic sheet collated nails Insert the fi rst nail into the driving hole and the second nail between the two pawls of the feeder. Fit the nail head and upper side of the plastic sheet in the guide slot. Fit the lower side of the plastic sheet in the guide slot for plastic sheets (Fig. 9). (4) Close the magazine cover fi rst and swing the nail guide closed (Fig. 10). (5) Lock the knob correctly. NOTE Be careful not to deform the collated wires and not to disengage the nails with the guide surface. Otherwise, the nail guide will not close correctly. CAUTION To prevent unintentional operation, never touch the trigger or place the top end of the push lever on a work bench or fl oor. Also, never face the nail outlet toward any part of a person. NOTE Before loading the nails in the magazine, position the nail holder according to the length of the nail. If the nail holder position is not adjusted properly, nail feed may jam. If the cover is forcibly closed without adjusting the position of the nail holder, the nail holder may be damaged.

HOW TO USE THE NAILER

CAUTION ○ Do not use the body or any portion of the tool as a hammer as nails may be discharged unexpectedly or the tool may become damaged and serious injury could occur. ○ Take precautions to ensure the safety of persons in the vicinity during operation. ○ Ensure tool is always safely engaged on the workpiece and cannot slip. ○ Never carry a pneumatic tool by its hose. ○ Never drag a pneumatic tool by its hose.

1. Set the lock lever to “Free” position

Turn the lock lever and align it with the “Free” position (Fig. 11).

2. How to drive nails

This product is a nailer using SINGLE SEQUENTIAL ACTUATION MECHANISM. If you pull the trigger fi rst, nothing will happen even if you press the push lever up against an object. Depress the nail outlet onto the desired point; then pull the trigger to drive a nail in a single shot (See Fig. 13). After nailing once, nailing will not be possible again until the trigger is released and pressed again. You cannot drive a nail by fi rst pulling on the trigger and then pressing the push lever against an object (continuous nailing). WARNING A nail will fi re each time the trigger is depressed as long as the push lever remains depressed. CAUTION Exercise care when nailing corners of lumber. When continuous nailing corners of lumber, a nail may go astray or break through the corner. NOTE ○ Precautions on no-load operation. Sometimes nailing will continue after driving in all nails previously contained in the magazine. This is termed “no-load operation”. Such operation may deteriorate the bumper, magazine, and nail feeder. To avoid no-load operation, occasionally confi rm the amount of remaining nails. On the other hand, all nails should be removed after using this nailer. ○ After completing operation, put into the body about 2 cc oil through the hose joint to protect the tool from rust. ○ Under low temperature conditions, the machine sometimes does not operate correctly. Always operate the machine at the appropriate ambient temperature.

3. Driving nails into steel plating

CAUTION ○ Use C-beam steel with a thickness of 3.2 mm or less. ○ Use hardened nails designed for use with steel plating. ○ Place the nailer vertically over the location into which the nail is to be driven. ○ Do not drive nails directly into C-beam steel or attach wire mesh laths, galvanized steel etc. directly onto it. ○ Do not use the nailer on roofs or ceilings. ○ Make sure that the thickness of the hardened nails designed for use with steel plating are of the correct thickness for the C-beam steel. NOTE Use the single shot setting to improve the fi nish after the nails have been driven in. Refer to the following table to select the correct nail shaft diameter and length. [Selecting Nail Shaft Diameter] C-Beam Steel Thickness Nail Shaft Diameter

2.3 mm or less 2.8 mm

3.2 mm or less 3.0 mm

[Selecting Nail Length] Material Thickness Nail Length 14 to 35 mm 45 mm 15 to 45 mm 50 mm C-beam Steel (Thickness: 1.6 mm to a maximum of 3.2 mm) Material Thickness Approximately 10 to 35 mm NOTE ○ Holding power will be greatly decreased if nails are driven too hard into steel plating. Rotate the adjuster downwards to adjust the depth of the nails. ○ There are cases in which the nails will not be driven in suffi ciently depending on a combination of the hardness and thickness of the C-beam or material. 0000NV90HMC.indb440000NV90HMC.indb44 2019/07/3111:33:442019/07/3111:33:4445 English The external material and steel plating is not deformed. The external material and steel plating is deformed.

4. Driving nails into concrete

CAUTION ○ Use hardened nails designed for use with concrete. ○ Place the nailer vertically over the location into which the nail is to be driven. ○ Do not drive nails directly into concrete or attach metal plates directly onto it. ○ Do not drive nails into the edge of concrete. ○ Do not use the nailer in locations from which other items are suspended (suspended pipes, etc.). NOTE Only use the nailer on concrete that has not yet set, soon after it has been poured. Using the nailer on hardened concrete may result in bent nails and nails being insuffi ciently driven in. [Selecting hardened nails for use with concrete] Select nails with a concrete intrusion depth of between 10 to 15 mm. Reference Examples Wood Thickness Length of Nails to be Used Concrete Intrusion Depth 30 mm 45 mm Approx. 15 mm 35 mm 50 mm Approx. 15 mm 45 mm 57 mm Approx. 12 mm 50 mm 65 mm Approx. 15 mm Length of Nails to be Used Wood Thickness Concrete Intrusion Depth 10 to 15 mm NOTE The nails will not be driven in suffi ciently if the concrete intrusion depth is deeper than 15 mm.

5. Adjusting the nail-driving depth

CAUTION When making adjustments, be sure remove your fi nger from the trigger. When making adjustments, be sure that the nail outlet is not facing downward and that body parts or other people are not in the path of the nail outlet. ○ Adjusting the adjuster (Fig. 14) Carry out test driving. If the nails are too deep, turn the adjuster to the shallow side ( mark). If the nail depth is too shallow, turn the adjuster to the deep side ( mark) (See Fig. 14, 15). Depth is changed 1 mm with each rotation of the adjuster. NOTE ○ When adjusting the adjuster, it does not rotate more than 3 mm from the deepest point where a nail goes down. Do not rotate the adjuster by force beyond that point. ○ The nail-driving depth can also be adjusted by changing the air pressure used. Carry this out together with movement of the adjuster. Using a high air pressure that does not match the nail-driving resistance will shorten the life of this nailer.

6. Cutting off the sheet

CAUTION ○ Be sure to release your fi nger from the trigger before using the blow nozzle. ○ Do not point the air outlet at a person. ○ Do not use the blow nozzle with the push lever left fi t. This Nailer has a blow nozzle that blows out wood shavings which occur during work. Press the knob with your thumb to use the blow nozzle (See Fig. 17). NOTE ○ When the blow nozzle is used for a long time, the nailing force may degrade temporarily. In this case, allows the air supply pressure to stabilize before starting work. ○ Oil in the body or drained water from the compressor can sometimes spout out of the air outlet. It is recommended that you once conduct a test before use and see if such phenomenon happens at an environment where spouted oil will cause any inconvenience.

8. How to use nosecap

CAUTION Remove the hose from the nailer and release the compressed air before installing or removing the nosecap to prevent accidental nail ejection. ○ Attach the nose cap on the tip of the push lever when you wish to protect the surface of wood, etc., from scratches. (1) Attaching and detaching nose cap The nose cap can be attached by simply pressing it into the push lever. Press it in until a convex part inside the nose cap enters into a hole of the push lever. (Fig. 18) For removal, insert a thin rod such as a screw driver into the gap on the back of the push lever, and then pull it out. (2) Safekeeping of nose cap Put the removed nose cap in a space behind the magazine for safekeeping. (Fig. 19)

INSPECTION AND MAINTENANCE

CAUTION Be sure to disconnect the hose during cleaning jams, inspection, maintenance and cleaning.

1. Countermeasure for nail jamming

(1) Remove the nail roll from the magazine, open the nail guide, insert a rod into the outlet and tap the rod with a hammer (Fig. 20). (2) Remove the jammed nail with slotted screw driver (Fig. 21). (3) Cut off the defective part of the steel wire which links the nails with cutting nippers, correct the deformation, then load the nail roll in the magazine. (4) In case of frequent jams, consult the Authorized Service Center from which you bought this machine. 0000NV90HMC.indb450000NV90HMC.indb45 2019/07/3111:33:442019/07/3111:33:4446 English

2. Check on mounting screws for each part

At regular intervals check every part for loose mounting screws and whether or not there are any air leaks. Retighten any loose screws. Operating the equipment with loose screws untightened will incur a hazard.

3. Inspecting the push lever

Check if the push lever can slide smoothly (Fig. 22). Clean up the sliding area of the push lever and use the provided oil for lubrication from time to time. Lubrication enables smooth sliding and simultaneously serves to prevent the formation of rust.

4. Inspecting the feeders

(1) Occasionally clean the knob sliding part and then apply the recommended oil (See Fig. 22). (2) Open the nail guide and remove dust, etc., as shown in Fig. 23. Apply lubricant to the sliding groove of the feeder and shaft. Check the nail stopper (A) and nail stopper (B) slide smoothly by pushing them with your fi nger. (3) Also, apply the recommended oil to the feeding sur face of the nose and nail guide after cleaning. This promotes smooth operation and retards corrosion. CAUTION Check for smooth movement of the feeders and stoppers before use. If movement is uneven, nails could be fi red at an irregular angle, presenting a hazard to the operator and others nearby.

5. Inspect the Trigger

Periodically clean the sliding parts of the trigger, and make sure that the trigger moves smoothly (Fig. 24).

6. Inspecting the muffl er

This Nailer has a built-in muffl er in the exhaust to reduce noise and stirred-up dust during exhaust. When the mesh of the muffl er is fi lled or the muffl er is damaged, replace the muffl er with a new one. To replace the muffl er, contact our Authorized Service Center (Fig. 25).

7. Inspecting the magazine

Clean the magazine. Remove dust of wooden chips which may have accumulated in the magazine.

○ When not in use for an extended period, apply a thin coat of the lubricant to the steel parts to avoid rust. ○ Do not store the Nailer in a cold weather environment. Keep the Nailer in a warm area. ○ When not in use, the Nailer should be stored in a warm and dry place. Keep out of reach of children. CAUTION In the operation and maintenance of power tools, the safety regulations and standards prescribed in each country must be observed. COMPRESSOR CAUTION When the maximum, operating pressure of the air compressor exceeds 23 bar (320 psi), be sure to provide a reducing valve between the air compressor and nailer. Then, adjust the air pressure within the operating range of 12 – 23 bar (170 – 320 psi). If the air set is installed, lubrication is also possible, thus providing additional convenience. APPLICABLE LUBRICANTS Type of lubricant Name of lubricant Recommended oil SHELL TONNA Motor oil SAE10W, SAE20W Turbine oil ISO VG32 - 68 (#90 - #180) Noise Information Noise characteristic values in accordance with EN ISO 1114 8-13:2018: The typical A-weighted single-event sound power level

WA,1s,d = 98.9 dB. The typical A-weighted single-event emission sound pressure level at work station

pA,1s,d = 93.0 dB. Uncertainty K: 2.5 dB (A) These values are tool-related characteristic values and do not represent the noise development at the point of use. Noise development at the point of use will for example depend on the working environment, the workpiece, the workpiece support and the number of driving operations, etc. Depending on the conditions at the workplace and the form of the workpiece, individual noise attenuation measures may need to be carried out, such as placing workpieces on sound-damping supports, preventing workpiece vibration by means of clamping or covering, adjusting to the minimum air pressure required for the operaion involved,etc. In special cases it is necessary to wear hearing protection equipment. Vibration Information The typical vibration characteristic value in accordance with EN ISO 11148-13:2018, 2000 : 6.5 m/s
