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 4.9 bar – 8.3 bar (70 ~ 120 psi.), and that the air which is used is clean and dry. If the air pressure is greater than 8.3 bar (120 psi.), the service life of the power tool will be shortened and dangerous condi- tions could develop. Tools shall not be connected to pressure which potentially exceeds 14 bar (200 psi.).

3. Never operate the equipment with high-pressure

gases other than compressed air. Never use carbon dioxide, oxygen or other gases from pressurized containers under any cir- cumstances.

4. Be careful of ignition and explosions.

Since sparks may fly during nailing, it is dangerous to use this tool near lacquer, paint, benzine, thinner, gasoline, gas, adhesives and similar inflammable substances as they may ignite or explode. Under no circumstances should this tool therefore be used in the vicinity of such inflammable 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 prescrip- tion glasses. Employers should always enforce the use of eye protection equipment.

6. Protect your ears and head.

When engaged in nailing work, please wear ear mufflers and head protection. Also, depending on condition, ensure that surrounding people also wear ear mufflers and head protection.

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. There- fore, 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 toward people.

Always assume the tool contains fasteners. If the nail outlet is pointed toward people, serious accidents may be caused if you mistakenly operate 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 operate 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.

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 not2 English use the power tool until it has been inspected and repaired. 䡬 If merely pulling the trigger causes operating sound of drive bit movement occur, the power tool is faulty. 䡬 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. 䡬 Do not touch the trigger. 䡬 Do not allow the firing head to contact with any surface. 䡬 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.

1. Check the air pressure

CAUTION: The air pressure must be constantly maintained at 4.9 – 8.3 bar (70 – 120 psi.). Adjust the air pressure between 4.9 to 8.3 bar (70 – 120 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 specified limit. Note that excessive pres- sure may affect overall performance, service life, and safety.

(1) Prior to operating this nailer, be sure to provide an air set between the air compressor and this device. Lubri- cation through the air set offers smooth operation, extended service life, and anticorrosion. Adjust the oiler so that a single drop of oil is supplied at intervals of 5 to 10 nailing cycles. (2) It is recommended using the recommended oil (SHELL TONNA). Other applicable oils are listed. Never mix two or more types of different oils.

(1) Load nails in the magazine 䡬 Grip the nail guide and knob with fingers. Then depress the knob to open the nail guide towards the left. (See Fig. 1.) Nail Min. Max.

(.071”) Nail Guide4 English 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, the nail jams. If the cover is forcibly closed without adjusting the position of the nail holder, the nail holder may be damaged. (2) Load nails in the guide Extend the nail line from the magazine. Insert the first nail into the driving hole and the second nail between the pawls of the feeder. Insert the nail so that the nail head engages the guide slot. (Fig. 5) Fig. 5 (3) Close nail guide After making sure that the cover is closed, hook your finger to the nail guide and the knob, and while pushing the knob down, turn the nail guide clockwise to completely close it. (Fig. 6) The above operation completes the loading of nails. Fig. 6 NOTE: The nail guide may not close properly or the nails may not advance properly if the linked bands or nails do not enter into the indicated position or the nails come away from the guide surface or the wire linked nails are warped. CAUTION: To prevent unintentional operation, never touch the trigger or place the top end of the push lever on a work bench or floor. Also, never face the nail outlet toward any of a person. 䡬 Adjust the position of the nail holder according to the length of the nail. (Fig. 2) Fig. 2 For adjustment, turn the nail holder 1 counterclockwise about 90 degrees. Move the nail holder 2 up and down, adjust to the length of a nail to be used, and adjust the surface of the nail holder to the marked position of the magazine. Turn the nail holder 3 clockwise (about 90 degrees) until it goes click. (Fig. 3) Fig. 3 䡬 Load the nails in the magazine.

HOW TO USE THE NAILER

CAUTIONS: 䡬 Never use the head or body of this nailer as a hammer. 䡬 Take precautions to ensure the safety of persons in the vicinity during operation.

1. Nailing procedures

(1) Method of intermittently driving nails (single shot) The single-contact change lever is in the single shot position (see Fig. 8). This nailer includes a single shot structure to allow driving of a single nail by pushing down the push lever and pulling the trigger (see Fig. 7). CAUTIONS: 䡬 [Method of intermittently driving nails (single shot)] explained here is not [Sequential fire]. When Single- contact Change Lever is at the Single shot position, if the push lever is pushed up in a state where the trigger is pulled, only one piece of nail in the shooting muzzle is fired: Be careful! In the event it is used by Sequential fire, use the Sequential Fire Parts Set of Optical Accessory. 䡬 If you do not pull the trigger quickly and crisply while in the single shot mode, the nailer will bounce and shoot several nails instead of just one. To avoid this, be sure to pull the trigger quickly and crisply. Fig. 7 Fig. 8 䡬 Push lever When depressing the nail outlet, be sure to fully lift the push lever (see Fig. 7) to release the safety lock. Thus, nails cannot be driven without releasing the safety lock even though the trigger is pulled. (2) Method for consecutive driving of nails (contact drive) The single-contact change lever is in the contact driv- ing position (see Fig. 10). Use the accessory hexagon bar wrench to turn the single-contact change lever to the contact driving position. First pull back the trigger. Then press the nail outlet on the workpiece. Driving of nails will start. (Fig. 9) Fig. 9 Fig. 10 CAUTION: Exercise care when nailing corners of lumber. When consecutive nailing is carried out at corners of lumber, a nail may go astray or break through the corner. NOTES: 䡬 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 confirm the amount of remaining nails. On the other hand, all nails should be removed after using this nailer. 䡬 After completing operation, put into the body about 2cc oil through the hose joint to protect the tool from rust. 䡬 Under low temperature conditions, the machine some- times does not operate correctly. Always operate the machine at the appropriate ambient temperature.

2. Adjusting the nail-driving depth

CAUTION: When making adjustments, be sure to remove your finger from the trigger. When making adjustments, be Trigger Push Lever Single Shot Position Single-Contact Change Lever First, pull the Trigger Next, depress the nail outlet Contact Driving Position Single-Contact Change Lever6 English sure that the nail outlet is not facing downward and that body parts or other persons are not in the path of the nail outlet. 䡬 Adjusting the adjuster (Fig. 11) 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. 11, 12). The ajuster moves 0.5 mm every time it is rotated with a click. Fig. 11 Fig. 12 NOTES: 䡬 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. 䡬 The nail-driving depth can also be adjusted by chang- ing 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 service life of this nailer.

3. Changing the exhaust direction.

The direction of the exhaust vent can be changed within 360° by turning the head ring. (Fig. 13) Fig. 13

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 nail outlet and tap the rod with a hammer. (Fig. 14) (2) Remove the jammed nail with slotted-head screw- driver. (Fig. 15) Fig. 14 Fig. 15 (3) Cut off the defective part of the steel wire which links the nails with cutting nippers, correct the deforma- tion, then load the nail roll in the magazine. (4) In case of frequent jam, consult the Authorized Serv- ice Center from which you bought this nailer.

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 nailer with loose screws untightened will incur a hazard.

3. Inspecting the push lever

Check if the push lever can slide smoothly. (Fig. 16) Clean up the sliding area of the push lever and use the provided oil for lubrication from time to time. Lubri- cation enables smooth sliding and simultaneously serves to prevent the formation of rust. Hammer Rod Nail outlet Adjuster Deep Shallow Too deepFlush Too shallow Exhaust Vent Adjustable range of exhaust direction Head Ring Nail Slotted-head Screwdriver7 English Fig. 16

4. Inspecting the feeders

(1) Occasionally clean the knob sliding part and then apply the recommended oil. (See Fig. 17.) Fig. 17 (2) Open the nail guide and remove dust, etc., as shown in Fig. 18. Apply lubricant to the sliding groove of the feeder and feeder shaft. Check nail stopper (A) and nail stopper (B) slide smoothly by pushing them with your finger. Fig. 18 (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 stop- pers before use. If movement is uneven, nails could be fired at an irregular angle, presenting a hazard to the operator and others nearby.

5. Inspecting the muffler

This Nailer has a built-in muffler in the exhaust to reduce noise and stirred-up dust during exhaust. When the mesh of the muffler is filled or the muffler is damaged, replace the muffler with a new one. To replace the muffler, contact our Authorized Service Center. Fig. 19

6. Inspecting the magazine

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

䡬 When not in use for an extended period, apply a thin coat of the lubricant to the steel parts to avoid rust. 䡬 Do not store the Nailer in a cold weather environment. Keep the Nailer in a warm area. 䡬 When not in use, the Nailer should be stored in a warm and dry place. Keep out of reach of children.
