This power tool is powered by internal combustion device. This power tool shall only be used with dispensers for combustible gas which are listed in this handling instructions. WARNING Read all safety warnings, instructions, illustrations and specifi cations provided with this power tool. Failure to follow all instructions listed below may result in electric shock, fi re and/or serious injury. Save all warnings and instructions for future reference. The term “power tool” in the warnings refers to your mains- operated (corded) power tool or battery-operated (cordless) power tool.

a) Keep work area clean and well lit. Cluttered or dark areas invite accidents. b) Do not operate power tools in explosive atmospheres, such as in the presence of fl ammable liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes. c) Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.

2) Electrical safety

a) Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodifi ed plugs and matching outlets will reduce risk of electric shock. b) Avoid body contact with earthed or grounded surfaces, such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded. c) Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock. d) Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock. e) When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock. f) If operating a power tool in a damp location is unavoidable, use a residual current device (RCD) protected supply. Use of an RCD reduces the risk of electric shock.

a) Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use a power tool while you are tired or under the infl uence of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious personal injury. b) Use personal protective equipment. Always wear eye protection.

PRECAUTIONS ON USING GAS STRIP 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. Be careful of ignition and explosions.

This tool must not be used in a combustible environment or in presence of fl ammable liquids or gases. This tool produces hot exhaust gases that may ignite fl ammable materials and produces sparks. 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.

3. Explosion and fi re hazard.

The fuel cell is an aerosol dispensers with fl ammable contents. Pressured container and the propellant will remain in the fuel cell. Failure to follow instructions may result in explosion or fi re. MAX 50°C (120°F) Keep the power tool, fuel cells and battery away from sunshine and from temperature exceeding 50°C (120°F). Fuel cell and/or battery may burst, releasing fl ammable gas. Do not pierce or burn the container, even after use. Do not incinerate, refi ll, reclaim or recycle the fuel cell. Do not spray to a naked fl ame or any incandescent material. Keep away from ignition sources – No smoking. Keep out of the reach of children.

4. 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.

5. 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. 000BookNR90GC2.indb9000BookNR90GC2.indb9 2021/07/2011:28:472021/07/2011:28:4710 English

6. Use outside or well-ventilated areas.

This tool exhausts carbon monoxide which are a danger to health when inhaled. This tool shall not be used in enclosed or poorly ventilated areas. Do not inhale.

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 battery or fuel cell, 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. 14. Be sure not to apply the force downward onto the tool to the extent that the push lever is engaged. The Push Lever and Chamber operate in conjunction for this device. Before using the power tool make sure to check that the push lever operate properly. Without nails, fuel cell and battery loaded into the power tool, check the following. If abnormal operation occurs, do not use the power tool until it has been inspected and repaired. ○ Pull the Feeder knob with the device facing upward and press down the Push lever then confi rm that the Push lever securely returns to its original position. The Push lever operation becomes especially heavy in low temperatures and drive operations may not function. ○ With pulling back the feeder knob, the push lever must move smoothly. ○ With pulling back the feeder knob, the trigger must move smoothly. 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 battery.

When connecting the battery and loading nails in order not to fi re the tool by mistake, make sure of the followings. ○ 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.

– Flashing GREEN: Enough power remaining (The light turns steady during operation). – Flashing RED: Insuffi cient power remaining (The light turns steady during operation). – OFF: The battery is extremely empty. Charge the battery.

2. Insert fuel cell into the tool

(1) Pulling the latch and open the cell cover (See Fig. 6). (2) Insert the fuel cell into the tool (See Fig. 7). (3) Insert the stem of fuel cell into the hole of adaptor (See Fig. 8). (4) Close the cell cover.

(1) Insert nail strip into rear of magazine (See Fig. 9). (2) Slide the nail strip forward in the magazine (See Fig. 10). (3) Pull the nail feeder (B) back to engage the feeder knob to the nail strip (See Fig. 11). NOTE Use nail strip of more than 10 nails. The Nailer is now ready to operate. Removing the nails: Pull the feeder knob backward (See Fig. 12). Return the feeder knob forward quietly while pushing the nail feeder (B). Pull out nails from the back of the magazine (See Fig. 13). CAUTION To prevent unintentional operation, never touch the trigger or place the top end of the push lever on a work bench on fl oor. Also, never face the nail outlet toward any part of a person.

HOW TO USE THE NAILER

CAUTION ○ Do not use the housing 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. ○ Squeeze the trigger when drive a nail, otherwise the piston can not return correctly. ○ Make sure the nailing depth when the temperature is above 40°C or below 0°C. ○ Ensure tool is always safely engaged on the workpiece and cannot slip.

1. Nailing procedures

This power tool is equipped with a FULL SEQUENTIAL ACTUATION MECHANISM. (1) Intermittent nailing Depress the nail outlet onto the desired point; then pull the trigger to drive a nail in a single shot (See Fig. 15). After nailing once, nailing will not be possible again until the trigger is released and pressed again. (2) Push lever When depressing the nail outlet, be sure to fully lift the push lever (See Fig. 15) to release the safety lock. Thus, nails cannot be driven without releasing the safety lock even though the trigger is pulled. The machine employs a preventive mechanism for unloaded operation. The machine enters a state where the push lever cannot be pushed up. This takes place when the magazine is not loaded with nails or when the remaining number of nails becomes less than 8 or 9 (NR90GC2), 5 or 6 (NR90GR2). 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. ○ Use caution not to throw the push lever tip onto wood when the push lever cannot be pushed up. NOTE Under low temperature conditions, the tool sometimes does not operate correctly. Always operate the tool at the appropriate ambient temperature.

2. Adjusting the nailing depth (See Fig. 17, 18)

To assure that each nail penetrates to the same depth, be sure that the tool is always held fi rmly against the workpiece. If nails are driven too deep or shallow into the workpiece, adjust the nailing in the following order. Remove the fuel cell and the battery from the nailer (See Fig. 16). If nails are driven too deep, move the push lever to forward (See Fig. 17). If nails are driven too shallow, move the push lever to backward (See Fig. 18). Stop moving the push lever when a suitable position is reached for a nailing test. Connect the fuel cell and the battery to the nailer. ALWAYS WEAR EYE PROTECTOR. Perform a nailing test. Remove the fuel cell and the battery from the nailer. Choose a suitable position for the push lever. 000BookNR90GC2.indb15000BookNR90GC2.indb15 2021/07/2011:28:482021/07/2011:28:4816 English

If nails are jammed in fi ring head, remove it, and adjust the nailing in the following order. Remove the fuel cell and the battery from the Nailer. (See Fig. 16) Lock follower back in magazine and remove fasteners. Remove the bolts with wrench. (See Fig. 19) Pull magazine away from the fi ring head, and clear jam. (See Fig. 20) Connect the fuel cell and the battery to the Nailer. ALWAYS WEAR SAFETY GLASSES. NOTE Hook can be used as a hanger.

INSPECTION AND MAINTENANCE

CAUTION Be sure to remove the battery and fuel cell during clearing jams, inspection, maintenance and cleaning.

1. Inspecting the magazine

DISCONNECT BATTERY and FUEL CELL. Clean the magazine. Remove paper chips or wooden chips which may have accumulated in the magazine. Lubricate it with HiKOKI gas strip nailer lubricant.

2. Check on mounting screws for each part

At regular intervals check every part for loose mounting screws. 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 (See page 11)

○ 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 tool in a warm area. ○ When not in use, the tool should be stored in a warm and dry place. Keep out of reach of children. ○ Store the Nailer in a place in which the temperature is less than 40°C and out of reach of children. NOTE Storing lithium-ion batteries. Make sure the lithium-ion batteries have been fully charged before storing them. Prolonged storage (3 months or more) of batteries with a low charge may result in performance deterioration, signifi cantly reducing battery usage time or rendering the batteries incapable of holding a charge. However, signifi cantly reduced battery usage time may be recovered by repeatedly charging and using the batteries two to fi ve times. If the battery usage time is extremely short despite repeated charging and use, consider the batteries dead and purchase new batteries. CAUTION In the operation and maintenance of power tools, the safety regulations and standards prescribed in each country must be observed. Important notice on the batteries for the HiKOKI cordless power tools Please always use one of our designated genuine batteries. We cannot guarantee the safety and performance of our cordless power tool when used with batteries other than these designated by us, or when the battery is disassembled and modifi ed (such as disassembly and replacement of cells or other internal parts). APPLICABLE LUBRICANTS Use HiKOKI Gas Nailer lubricant. Do not use detergent oil or additives. These lubricants will harm the O-rings and other rubber parts. This will cause the tool malfunction. Noise Information Noise characteristic values in accordance with EN ISO 11148-13:2018: The typical A-weighted single-event sound power level

WA,1s,d = 108 dB The typical A-weighted single-event emission sound pressure level at work station L pA,1s,d = 99 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, 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: 3.5 m/s

The declared vibration total value and the declared noise emission value have been measured in accordance with a standard test method and may be used for comparing one tool with another. They may also be used in a preliminary assessment of exposure. WARNING ○ The vibration and noise emission during actual use of the power tool can diff er from the declared total value depending on the ways in which the tool is used especially what kind of workpiece is processed; and ○ Identify safety measures to protect the operator that are based on an estimation of exposure in the actual conditions of use (taking account of all parts of the operating cycle such as the times when the tool is switched off and when it is running idle in addition to the trigger time). 000BookNR90GC2.indb16000BookNR90GC2.indb16 2021/07/2011:28:482021/07/2011:28:4817 English NOTE Due to HiKOKI’s continuing program of research and development, the specifi cations herein are subject to change without prior notice.
