GENERAL OPERATIONAL PRECAUTIONS 1. Operate the power tool safely for correct uses. Do not use the power tool for uses other than those

speci ed in this instructions. 2. For safe operation handle the power tool correctly. Please follow the instructions given in this instruction

manual and correctly handle this tool so as to ensure safe operation. Never let the tool be use by children or people who do not know enough to be able to handle it correctly, or let it be used by people who cannot operate it correctly.

3. Con rm the safety of the workshop. Keep unauthorized people away from the workshop.

Especially children should be kept away. 4. The right parts in the right places. Do not remove any of the covers or screws. Keep them

in place as they have their functions. Moreover, because it would be dangerous, never

make modi cations to the tool or use it after making modi cations.

5. Check the tool before using it. Before using the tool, always check that no parts of it

are broken, that all screws are completely tight, and that no parts are missing or rusty.

6. Excessive work could cause accidents. Do not make tools and accessories work beyond their

abilities. Excessive work not only damages the power tool but also is dangerous in itself.

7. Stop operation immediately if abnormalities are noticed.

Stop operation if you notice abnormalities, or if the power tool does not work properly; have the power tool inspected and serviced.

8. Look after the power tool carefully. If you drop or knock the power tool against things, the

outer frame may be deformed and cracks or other kinds of damage may occur, so please handle it with su cient care. Also, do not scratch or engrave signs on the power tool. Owing to high pressure air inside the tool, cracks in the surface are dangerous.

Never use the power tool if a crack develops or if air is escaping from a crack.

9. Take good care for a long life. Always take good care of the power tool and keep it

clean. 10. Inspection at regular intervals is essential for

safety. Inspect the power tool at regular intervals so that the

power tool can be operated safety and e ciently at all times.

11. Consult an authorized service agent if repair or parts replacement is necessary.

Ensure that the power tool is serviced by authorized service agent only, and that only genuine replacement parts are used.

12. Keep the power tool in a proper place. When not in use, the power tool should be kept in a dry

place out of the reach of children. Put into the body 5-10 drops oil through the hose joint to protect the tool from rust.

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. Fastener driving tools operated by compressed air shall

only be connected to compressed air lines where the maximum allowable pressure cannot be exceeded by a factor of more than 10% which can for example be achieved by a pressure reduction valve which includes a downstream safety valve.

(For model NR83A5, 110% of rated maximum allowable pressure is 0.91 MPa = 9.1 bar)

Fastener driving tools operated by compressed air should only be operated at the lowest pressure required for the work process at hand, in order to prevent unnecessarily high noise levels, increased wear and resulting failures.

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 y during nailing, it is dangerous

to use this tool near lacquer, paint, benzine, thinner, gasoline, gas, adhesives and similar in ammable substances as they may ignite or explode. Under no circumstances should this tool therefore be used in the vicinity of such in 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 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.

6. Protect your ears and head. When engaged in nailing work please wear ear mu ers

and head protection. Also, depending on condition, ensure that surrounding people also wear ear mu ers 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. Therefore, always pay attention to the safety of the people around you when using this tool. Always make sure that nobodys 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. 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 modi ed or removed.

10. Use speci ed nails only. Never use nails other than those speci ed and

described in these instructions. 11. Be careful when connecting the hose. When connecting the hose and loading nails in order not

to re the tool by mistake, make sure of the followings. Do not touch the trigger. Do not allow the ring head to contact with any

surface. Keep the 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.

12. Do not carelessly place your nger on the trigger. Do not place your nger on the trigger except when

actually nailing. If you carry this tool or hand it to someone while having your nger on the trigger, you may inadvertently discharge a nail and thus cause an accident.

13. Press the nail outlet rmly against the material to be nailed.

When driving in nails, press the nail outlet rmly 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 ring head when using.

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

15. Beware of the tools 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 nobodys 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 sca oldings, ladders. The power tool shall not be used for speci c application

for example: when changing one driving location to another

involves the use of sca orldings, stairs, ladders or ladder alike constructions, e.g. roof laths,

closing boxes or crates, tting transportation safety systems e.g. on

vehicles and wagons 19. Do not disconnect the hose with your nger on the

trigger. If you disconnect the hose with your nger on the

trigger, the next time the hose is connected, there is a danger that the power tool will re 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 red by mistake.

21. When removing a nail which has become stuck, make sure to rst of all disconnect the hose and release compressed air.

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

Accidental ring 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.

APPLICATIONS Floor and wall framing. Truss build-up, Window build-up. Sub ooring and roof decking. Wall sheathing. Mobile home and modular housing construction.

PREPARATION PRIOR TO OPERATION 1. Prepare the hose Be sure to use the hose provided with minimum 8 mm

inside diameter. NOTE The air supply hoses must have a minimum working

pressure rating of 1.28 MPa (12.8 bar) or 150 percent of the maximum pressure produced in the air supply system, whichever is higher.

2. Check on safety CAUTION Unauthorized persons (including children) must be kept

away from the equipment. Wear eye protector. Check the retaining screws which x the exhaust cover,

etc. for tightness. Check the nailer for air leaks and defective or rusty

parts. Check whether or not the push lever works correctly.

Also check whether or not any dirt has adhered to the moving parts of the push lever.

Recheck on operational safety.

BEFORE USE 1. Check the air pressure CAUTION The air pressure must be constantly maintained at 0.49

0.83 MPa (4.9 8.3 bar). Adjust the air pressure between 0.49 to 0.83 MPa

(4.9 8.3 bar) 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 speci ed limit. Note that excessive pressure may a ect overall performance, service life, and safety.

2. Lubrication (1) Prior to operating this nailer, be sure to provide an

air set between the air compressor and this device. Lubrication through the air set o ers 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 di erent oils.

3. Load nails (1) Pull the nail feeder back until it latches (See Fig. 2). (2) Insert nail strips one by one from above the magazine

(See Fig. 3). Two strips can be loaded at one time. (3) Press the stop lever and slide the nail feeder forward

until it contacts the nail strip (See. Fig. 4) NOTE Quietly push the nail feeder against the nail. If the nail feeder is released from backward the

magazine and bumped against the nail, the connecting plastic of the nail can be damaged.

Use nail strip of the more than 5 nails.

The Nailer is now ready to operate.

Removing the nails: Press the stop lever and slide the nail feeder forward

quietly. Pull out nails from the top of the magazine.

CAUTION To prevent unintentional operation, never touch the

trigger or place the top end of the push lever on a work bench on oor. Also, never face the nail outlet toward any part of a person.

HOW TO USE THE NAILER CAUTIONS Never use the head or body of this device as a hammer. Take precautions to ensure the safety of persons in the

vicinity during operation. 1. Nailing procedures This HiKOKI nailer is equipped with a nailer operation

switching device. Use SINGLE SEQUENTIAL ACTUATION MECHANISM

or CONTACT ACTUATION MECHANISM in accordance with the work to be performed.

When shipped, the tool's drive mode is locked to SINGLE SEQUENTIAL ACTUATION MECHANISM with the lock pin.

By removing the lock pin as shown below, the tool can be switched between SINGLE SEQUETIAL ACTUATION and CONTACT ACTUATION.

(1) How to remove the lock pin Use a pair of pliers like the one shown below to pull o

the lock pin (See. Fig. 5). (2) Intermittent nailing Select SINGLE SEQUENTIAL ACTUATION MODE

according to the following steps. Open the change stopper by pushing the bottom of

trigger. Grasp the change rod between two ngers (one on

each side of the trigger) and slide it down (See. Fig. 6). Con rm that the change stopper has completely returned

to original position inside the trigger (See. Fig. 7). Depress the nail outlet onto the desired point; then pull

the trigger to drive a nail in a single shot (See Fig. 8). After nailing once, nailing will not be possible again until

the trigger is released and pressed again. WARNING A nail will re each time the trigger is depressed as long

as the push lever remains depressed. CAUTION 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.

(2) Push lever When depressing the nail outlet, be sure to fully lift the

push lever (See Fig. 8) to release the safety lock. Thus, nails cannot be driven without releasing the safety lock even though the trigger is pulled.

(3) Disconnect the air hose. When the hook is attached, do not operate with contact

actuation mechanism. (4) Continuous nailing Select CONTACT ACTUATION MECHANISM MODE

according to the following steps. Open the change stopper by pushing the bottom of

trigger. Grasp the change rod between two ngers (one on

each side of the trigger) and slide it up (See. Fig. 9). Con rm that the change stopper has completely returned

to original position inside the trigger (See. Fig. 10). First, pull the trigger. Then depress the devise onto

the desired position to automatically drive nails (See Fig. 11).

The SINGLE SEQUENTIAL ACTUATION MECHANISM is for use where precision fastener placement is desired.

The SINGLE SEQUENTIAL ACTUATION MECHANISM may reduce the possibility of bodily injury to you or others in the work area compared to the CONTACT ACTUATION MECHANISM. This is because it is less likely to drive an unwanted nail if you keep the trigger pulled and accidentally bump the push lever against yourself or others. The SINGLE SEQUENTIAL ACTUATION MECHANISM may also reduce the speed of operation compared to the CONTACT ACTUATION MECHANISM. The SINGLE SEQUENTIAL ACTUATION MECHANISM is recommended to inexperienced users.

CAUTION Exercise care when nailing corners of lumber. When

continuous nailing corners of lumber, a nail may go astray or break through the corner.

Do not drive a nail on another nail. Do not drive a nail on metal parts. 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 damper, magazine, and nail feeder.

To avoid no-load operation, occasionally con rm the amount of remaining nails. On the other hand, all nails should be removed after using this nailer.

Always handle nails and package carefully. If nails are dropped, collating bond may be broken.

After nailing: (1) disconnect air hose from the nailer; (2) remove all nails from the nailer; (3) supply 5 10 drops of HiKOKI pneumatic tool

lubricant into the air plug on the nailer; and (4) open the petcock on the air compressor tank to

drain any moisture. Under low temperature conditions, the machine

sometimes does not operate correctly. Always operate the machine at the appropriate ambient temperature.

2. Adjusting the nailing depth (See Fig. 12) To assure that each nail penetrates to the same depth,

be sure that: (1) the air pressure to the Nailer remains constant

(regulator is installed and working properly), and (2) the Nailer is always held rmly against the

workpiece. If nails are driven too deep or shallow into the workpiece,

adjust the nailing in the following order. DISCONNECT AIR HOSE FROM NAILER. If nails are driven too deep, turn the adjuster to the

shallow side. If nails are driven too shallow, turn the adjuster to

the deep side. Stop turning the adjuster when a suitable position is

reached for a nailing test. Connect the air hose.

ALWAYS WEAR EYE PROTECTOR. Perform a nailing test.

DISCONNECT AIR HOSE FROM NAILER. Choose a suitable position for the adjuster.

3. Rafter hook With the nailer, an included hook can be attached by

using three M5 16 ange bolts which are included with the tools.

When the tool is detached from the hose and not in use, the hook can be used to store the unit.

(1) How to attach the hook. When attaching, use a hexagonal bar wrench for M5

(separate). Fix the hook to main unit in three locations using M5

ange bolts (See. Fig. 13). Fastening Torque

8.30.5 N m 6.10.4 ft.lbs 855 kgf cm

The hook can be attached in any direction. Adjust the hook according to the operating environment

(See. Fig. 14). (2) How to detach the hook. Detach the hook by reversing the aforementioned step

for attaching the hook. CAUTION When the hook attached, operate only with SINGLE

SEQUENTIAL ACTUATION MECHANISM and not with CONTACT ACTUATION MECHANISM.

Disconnect the air hose when hook the unit. Do not hook on high or unstable locations. Also, do

not hook it to the body, clothing, belt or other personal items.

INSPECTION AND MAINTENANCE CAUTION Be sure to disconnect the hose during cleaning jams,

inspection, maintenance and cleaning. 1. Inspecting the magazine

DISCONNECT AIR HOSE. Clean the magazine. Remove paper chips or wooden

chips which may have accumulated in the magazine. Lubricate it with HiKOKI pneumatic tool lubricant.

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. 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. Storing 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 0.83 MPa (8.3 bar), be sure to provide a reducing valve between the air compressor and nailer. Then, adjust the air pressure within the operating range of 0.49 0.83 MPa (4.9 8.3 bar). If the air set is installed, lubrication is also possible, thus providing additional convenience.

OILER-FILTER-REDUCING VALVE (Air Set) So that the equipment can be operated under an optimum condition to ensure extended service life, it is recommended to use an oiler lter reducing valve. Please limit the length of the hose between the unit and the air set to within 10 m when using (See Fig. 15).
