GENERAL POWER TOOL SAFETY WARNINGS

WARNING
Read all safety warnings and all instructions. Failure to follow the warnings and instructions 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.

1. Work area safety

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

2. Electrical safety

   • 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. Unmodified plugs and matching outlets will reduce the risk of electric shock.
   • 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.
   • Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
   • Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep the cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock.
   • When operating a power tool outdoors, use an extension cord suitable for outdoor use. The use of a cord suitable for outdoor use reduces the risk of electric shock.
   • If operating a power tool in a damp location is unavoidable, use a residual current device (RCD) protected supply. The use of an RCD reduces the risk of electric shock.

3. Personal safety

   • 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 influence of drugs, alcohol or medication.
     A moment of inattention while operating power tools may result in serious personal injury.

   • Use personal protective equipment. Always wear eye protection.
     Protective equipment such as dust masks, non-skid safety shoes, hard hats, or hearing protection used for appropriate conditions will reduce personal injuries.

   • Prevent unintentional starting. Ensure the switch is in the off position before connecting to the power source and/or battery pack, picking up or carrying the tool. Carrying power tools with your finger on the switch or energising power tools that have the switch on invites accidents.

   • Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personal injury.

   • Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.

   • Dress properly. Do not wear loose clothing or jewellery. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts.

   • If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. The use of dust collection can reduce dust-related hazards.

4. Power tool use and care

   • Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and safer at the rate for which it was designed.
   • Do not use the power tool if the switch does not turn it on and off . Any power tool that cannot be controlled with the switch is dangerous and must be repaired.
   • Disconnect the plug from the power source and/or the battery pack from the power tool before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.
   • Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool. Power tools are dangerous in the hands of untrained users.
   • Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tool operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools.
   • Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
   • Use the power tool, accessories tool bits etc. under these instructions, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from those intended could result in a hazardous situation.

5. Battery tool use and care

   • Recharge only with the charger specifi ed by the manufacturer. A charger that is suitable for one type of battery pack may create a risk of fire when used with another battery pack.
   • Use power tools only with specifi cally designated battery packs. Use of any other battery packs may create a risk of injury and fi re.
   • When the battery pack is not in use, keep it away from other metal objects, like paper clips, coins, keys, nails, screws or other small metal objects, that can make a connection from one terminal to another. Shorting the battery terminals together may cause burns or a fi re.
   • Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact accidentally occurs, flush with water. If liquid contacts the eyes, additionally seek medical help. Liquid ejected from the battery may cause irritation or burns.

6. Service

   • Have your power tool serviced by a qualifi ed repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained.

PRECAUTION
Keep children and infi rm persons away.
When not in use, tools should be stored out of reach of children and infi rm persons.

CORDLESS BRAD NAILER SAFETY WARNINGS

1. Always assume that the tool contains fasteners. Careless handling of the nailer can result in unexpected fi ring of fasteners and personal injury.
2. Do not point the tool towards yourself or anyone nearby. Unexpected triggering will discharge the fastener causing an injury.
3. Do not actuate the tool unless the tool is placed firmly against the workpiece. If the tool is not in contact with the workpiece, the fastener may be deflected away from your target.
4. Disconnect the tool from the power source when the fastener jams in the tool. While removing a jammed fastener, the nailer may be accidentally activated if it is plugged in.
5. Use caution while removing a jammed fastener. The mechanism may be under compression and the fastener may be forcefully discharged while attempting to free a jammed condition.
6. Do not use this nailer for fastening electrical cables. It is not designed for electric cable installation and may damage the insulation of electric cables thereby causing electric shock or fi re hazards.

ADDITIONAL SAFETY WARNINGS

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. Since sparks may fl y during nailing, it is dangerous to use this tool near lacquer, paint, benzene, 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.

3. 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.

4. Protect your ears and head.
   When engaged in nailing work please wear ear muffl ers and head protection. Also, depending on the condition, ensure that surrounding people also wear ear mufflers and head protection.

5. Pay attention to those working close to you.
   It would be very dangerous if nails that were not properly driven 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.

6. 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, 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.

7. Check the push lever before use.
   Make sure the push lever operates properly. (The push lever may be called “Safety”.) Never use the Nailer unless the push lever is operating properly, otherwise the Nailer could drive a fastener unexpectedly. Do not tamper with or remove the push lever, otherwise the push lever becomes inoperable.

8. The choice of triggering method is important.
   Read and understand the section titled “HOW TO USE THE NAILER” on page 16.

9. Before using this product, make sure that it is operating properly under the content of “Testing the nailer” on page 15.

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

11. Be careful when connecting the battery.
    When connecting the battery and loading nails in order not to fire 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.

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

13. 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.

14. 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.

15. 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.

16. Be careful of double fi re due to recoil.

    • If the push lever is unintentionally allowed to re-contact the workpiece following the recoil, an unwanted fastener will be driven.
    • In order to avoid this undesirable double fire,
    • Intermittent operation (Trigger fi ring)
    1. Set the switching device to SINGLE SEQUENTIAL ACTUATION MECHANISM.
    2. Pull the trigger rapidly and fi rmly.
    3. Continuous operation (Push lever fi ring)
    4. Do not press the nailer against the wood with excessive force.
    5. Separate the nailer from the wood as it recoils after fastening.

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 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.

19. Do not use the power tool on scaff oldings, or ladders. The power tool shall not be used for specifi c applications for example:

    • when changing one driving location to another involves the use of scaffoldings, stairs, ladders or ladder-alike constructions, e.g. roof laths,
    • closing boxes or crates,
    • fitting transportation safety systems e.g. on vehicles and wagons

20. Remove all remaining fasteners and battery from the nailer when:

21. doing maintenance and inspection;

22. checking proper operation of the push lever and trigger;

23. attaching or removing the nose cap;

24. clearing a jam;

25. it is not in use;

26. leaving the work area;

27. moving it to another location; and

28. handing it to another person.
    Never attempt to clear a jam or repair the Nailer unless you have removed the battery and all remaining fasteners from the Nailer.
    The Nailer should never be left unattended since people who are not familiar with the Nailer might handle it and injure themselves.

29. Remove battery from nailer when:

30. loading nails;

31. turning the adjuster.

32. Disconnect the battery.

    • When attaching and detaching the nose cap, disconnect the battery.
    • When attaching the accessory nose cap to the tip of the push lever and when detaching it, make sure to disconnect the battery beforehand. It is very dangerous for a nail to be fi red by mistake.

33. The operating environment for this device is between 0°C and 40°C so ensure use within this temperature range. The device may fail to operate below 0°C or above 40°C.

34. Always charge the battery at an ambient temperature of 0–40°C.
    A temperature of less than 0°C will result in overcharging which is dangerous. The battery cannot be charged at a temperature greater than 40°C. The most suitable temperature for charging is that of 20–25°C.

35. Do not use the charger continuously. When one charging is completed, leave the charger for about 15 minutes before the next charging of the battery.

36. Do not allow foreign matter to enter the hole for connecting the rechargeable battery.

37. Never disassemble the rechargeable battery or charger.

38. Never short-circuit the rechargeable battery. Short-circuiting the battery will cause a great electric current and overheat. It results in burn or damage to the battery.

39. Do not dispose of the battery in fi re. If the battery is burnt, it may explode.

40. Using an exhausted battery will damage the charger.

41. Bring the battery to the shop from which it was purchased as soon as the post-charging battery life becomes too short for practical use. Do not dispose of the exhausted battery.

42. Do not insert objects into the air ventilation slots of the charger. Inserting metal objects or fl ammable into the charger air ventilation slots will result in an electrical shock hazard or damage to the charger.

43. NEVER allow magnets (or similar magnetic devices) to be adjacent to the nailer, because the nailer has a magnetic sensor inside. Doing so will cause a failure or risk of injury by malfunction.

44. Resting the unit after continuous work.

45. The power tool is equipped with a temperature protection circuit to protect the motor. Continuous work may cause the temperature of the unit to rise, activating the temperature protection circuit and automatically stopping operation. If this happens, allow the power tool to cool before resuming use.

CHARGING

Before using the power tool, charge the battery as follows.

1. Connect to the power source. (Fig. 3)

   • Connect the charger’s power cord to the receptacle. When connecting the plug of the charger to a receptacle, the pilot lamp will blink in red (At 1- 1-second intervals).
     CAUTION
     Do not use the electrical cord if damaged. Have it repaired immediately.

2. Insert the battery into the charger.
   Firmly insert the battery into the charger as shown in Fig. 3.

3. Charging
   When inserting a battery in the charger, charging will commence and the pilot lamp will light up continuously in red. When the battery becomes fully recharged, the pilot lamp will blink in red. (At 1-second intervals) (See Table 1)

4. Pilot lamp indication
   The indications of the pilot lamp will be as shown in Table 1, according to the condition of the charger or the rechargeable battery.
   Table 1

5. Regarding the temperatures of the rechargeable battery The temperatures for rechargeable batteries are as shown in Table 2, and batteries that have become hot should be cooled for a while before being recharged.
   Table 2 Recharging ranges of batteriesRechargeable batteries| Temperatures at which the battery can be recharged
   ---|---
   BSL1820M| 0°C–50°C

6. Regarding recharging time
   Depending on the combination of the charger and batteries, the charging time will become as shown in Table 3.
   Table 3 Charging time (At 20°C)Charger/Battery| UC18YFSL
   ---|---
   BSL1820M| Approx. 30 min

NOTE
The recharging time may vary according to the ambient temperature and power source voltage.
CAUTION
When the battery charger has been continuously used, the battery charger will be heated, thus constituting the cause of the failures. Once the charging has been completed, give 15 minutes rest until the next charging.

4. Disconnect the charger’s power cord from the receptacle.
5. Hold the charger fi rmly and pull out the battery.
   NOTE
   Be sure to pull out the battery from the charger after use, and then keep it.

Regarding electric discharge in case of new batteries, etc.
As the internal chemical substance of new batteries and batteries that have not been used for an extended period is not activated, the electric discharge might be low when using them the first and second time. This is a temporary phenomenon, and the normal time required for recharging will be restored by recharging the batteries 2–3 times.

How to make the batteries perform longer

1. Recharge the batteries before they become completely exhausted.
   When you feel that the power of the tool becomes weaker, stop using the tool and recharge its battery. If you continue to use the tool and exhaust the electric current, the battery may be damaged and its life will become shorter.

2. Avoid recharging at high temperatures.
   A rechargeable battery will be hot immediately after use. If such a battery is recharged immediately after use, its internal chemical substance will deteriorate, and the battery life will be shortened. Leave the battery and recharge it after it has cooled for a while.

CAUTION

• If the battery is charged while it is heated because it has been left for a long time in a location subject to direct sunlight or because the battery has just been used, the pilot lamp of the charger lights up green. In such a case, fi rst let the battery cool, then start charging.
• When the pilot lamp fl ickers in red (at 0.2-second intervals), check for and take out any foreign objects in the charger’s battery connector. If there are no foreign objects, the battery or charger is probably malfunctioning. Take it to your authorized Service Center.
• Since the built-in microcomputer takes about 3 seconds to confirm that the battery being charged with the charger is taken out, wait for a minimum of 3 seconds before reinserting it to continue charging. If the battery is reinserted within 3 seconds, the battery may not be properly charged.
• If the pilot lamp does not blink in red (every second) even though the charger cord is connected to the power, it indicates that the protection circuit of the charger may be activated.
  Remove the cord or plug from the power and then connect it again after 30 seconds or so. If this does not cause the pilot lamp to blink in red (every second), please take the charger to the HiKOKI Authorized Service Center.

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.

Explanation of the various nailing operations

• SINGLE SEQUENTIAL ACTUATION MECHANISM: First, press the push lever against the wood; next, pull the trigger to drive the nail.
  After nailing once, nailing will not be possible again until the trigger is released and pressed again.

• CONTACT ACTUATION MECHANISM:

  1. Pull the trigger.
  2. Press the push lever against the wood to drive the nail.
  3. If the trigger is held back, a nail will be driven each time the push lever is pressed against the wood.

• Nailing procedures
  This Nailer is equipped with a push lever and does not operate unless the push lever is depressed.
  There are two methods of operation to drive nails with this Nailer.
  They are:

  1. Intermittent operation (Trigger fire):
  2. Continuous operation (Push lever fire):

1. Intermittent operation (Trigger fire)
   Use the SINGLE SEQUENTIAL ACTUATION MECHANISM setting. (See Fig. 12)

WARNING

• For intermittent operation, Set the nailing operation switch to SINGLE SEQUENTIAL ACTUATION MECHANISM (Nailing operation indicator is light in blue.) (i.e. Set to SINGLE ACTUATION MECHANISM.)
• To avoid double fi ring or accidental fi ring due to recoil.
  1. Set to SINGLE SEQUENTIAL ACTUATION MECHANISM.
  2. Pull the trigger rapidly and firmly.

1. Set the nailing operation switch to SINGLE SEQUENTIAL ACTUATION MECHANISM (The nailing operation indicator is light in blue.)
2. Position the nail outlet on the workpiece with your finger off the trigger.
3. Depress the push lever firmly until it is completely depressed.
4. Pull the trigger to drive a nail.
5. Remove the finger from the trigger and lift the tool off the wood surface completely.
   To continue nailing in a separate location, move the nailer along the wood, repeating steps 1– 2 as required.

NOTE
Operations 3 and 4 should be done within 4 seconds of each other. If more than 4 seconds pass after, the Nailer will not work properly. If this happens, retry from 3.

Continuous operation (Push lever fi re)
Using CONTACT ACTUATION MECHANISM (See Fig. 13)

WARNING
To avoid double fi ring or accidental fi ring due to recoil.

1. Do not press the nailer against the wood with excessive force.
2. Separate the nailer from the wood as it recoils after nailing.
3. Set the nailing operation switch to CONTACT ACTUATION MECHANISM (The nailing operation indicator is blinks in blue.)
4. Pull the trigger with the Nailer off the workpiece.
5. Depress the push lever against the workpiece to drive a nail.
6. Move the Nailer along the workpiece with a bouncing motion. Each depression of the push lever will drive a nail.

As soon as the desired number of nails has been driven, remove the finger from the trigger.

NOTE
Operations 2 and 3 should be done within 2 seconds of each other. If more than 2 seconds pass after 2, the Nailer will not work properly. If this happens, retry from 2.

WARNING

• Keep your fi nger off the trigger except during nailing operation, because serious injury could result if the push lever accidentally contacts you or others in work area.
• Keep hands and body away from the discharge area. This HiKOKI nailer may bounce from the recoil of driving a nail and an unwanted subsequent nail may be driven, possibly causing injury.

NOTE

• If all warnings and instructions are followed, safe operation is possible with all two systems: SINGLE SEQUENTIAL ACTUATION MECHANISM, CONTACT ACTUATION MECHANISM.
• Always handle nails and package carefully. If nails are dropped, collating bond may be broken, which will cause mis-feeding and jamming.

After nailing:

1. remove battery from the Nailer;
2. remove all nails from the Nailer;

Adjusting the nailing depth
To assure that each nail penetrates to the same depth, be sure that the Nailer 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.

1. Remove the battery from the Nailer.
2. If nails are driven too deep, turn the adjuster to the shallow side. (See Fig. 14) Adjustments are in half-turn increments.
   If nails are driven too shallow, turn the adjuster to the deep side. (See Fig.

3. Stop turning the adjuster when a suitable position is reached for a nailing test.
4. Connect the battery to the Nailer. ALWAYS WEAR SAFETY GLASSES. Perform a nailing test.
5. Remove the battery from the Nailer.
6. Choose a suitable position for the adjuster.

Using the hook (See Fig. 16)

WARNING
When using the hook, turn off the power switch (green light “OFF”). Pay sufficient attention so that the main equipment does not fall. If the tool falls, there is a risk of an accident.

The hook can be installed on the left or right side.

1. Remove the battery, then remove all remaining nails from the magazine.
2. Securely hold the main unit and remove the screw using a screwdriver.
3. Remove the hook.
4. Install the hook on the other side and securely fasten it with a screw.

NOTE
The hook can be used as a hanger.

WARNING
When attaching or detaching the nose cap, be sure to remove your finger from the trigger and remove all remaining fasteners and the battery from the nailer.

If you like to protect the surface of the workpiece against scratches or markings made by the push lever, attach the accessory nose cap to the push lever.

1. Remove all remaining fasteners and batteries from the nailer.
2. Put the nose cap on the toe of the push lever.
3. When not using the nose cap, secure it in the storage compartment located on the reverse side of the magazine.

NOTE
The nose cap may reduce nailing depth due to its thickness. Re-adjustment of nailing depth is required.

Clearing a jam
If nails are jammed in the ring head, remove it, and adjust the nailing in the following order.

CAUTION
Remove the battery from the Nailer.

1. Remove the battery from the Nailer.
2. Remove all nails.
3. Release the Lock lever and open the guide plate. (See Fig. 18)
4. Remove the jammed nail with a slotted-head screwdriver. (See Fig. 19)

CAUTION

• NEVER hit the driver’s blade.
• NEVER point the tool at yourself or another person, to avoid risk of injury by mis-fi ring. Even if the battery is removed from the nailer, there is still energy of compressed air remaining inside.

Close the guide plate and latch.

NOTE

MAINTENANCE AND INSPECTION

CAUTION
Be sure to remove all remaining fasteners and batteries from the nailer before maintenance and inspection.

1. Inspecting the magazine

2. Remove the battery from the Nailer.

3. Clean the magazine. Remove dust and wooden chips which may have accumulated in the magazine.
   CAUTION
   Check that the nail feeder slides smoothly by pulling it with a finger.
   If not smooth, nails can be driven at an irregular angle and hurt someone.

4. Inspecting the mounting screws
   Regularly inspect all mounting screws and ensure that they are properly tightened. Should any of the screws be loose, retighten them immediately. Failure to do so could result in serious hazards.

5. Maintenance of the motor
   The motor unit winding is the very “heart” of the power tool. Exercise due care to ensure the winding does not become damaged and/or wet with oil or water.

6. Cleaning on the outside
   When the power tool is stained, wipe with a soft dry cloth or a cloth moistened with soapy water. Do not use chloric solvents, gasoline or paint thinner, for they melt plastics.

7. Storage
   Store the power tool 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, significantly reducing battery usage time or rendering the batteries incapable of holding a charge.
• However, significantly reduced battery usage time may be recovered by repeatedly charging and using the batteries two to five 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 those designated by us, or when the battery is disassembled and modified (such as disassembly and replacement of cells or other internal parts).

GUARANTEE
We guarantee HiKOKI Power Tools per statutory/country specific regulation. This guarantee does not cover defects or damage due to misuse, abuse, or normal wear and tear. In case of complaint, please send the Power Tool, undismantled, with the GUARANTEE CERTIFICATE found at the end of this Handling instruction, to a HiKOKI Authorized Service Center.

Noise Information
Noise characteristic values following EN60745:

• The typical A-weighted single-event sound power level LWA,1s,d = 79 dB
• The typical A-weighted single-event emission sound pressure level at workstation LpA,1s,d = 68 dB
• Uncertainty KpA: 3 dB

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 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 using clamping or covering, etc.

In special cases, it is necessary to wear hearing protection equipment.

Vibration Information

• The typical vibration characteristic value by EN60745: 2.1 m/s2
• Uncertainty K: 1.5 m/s2

This value is a tool-related characteristic value and does not represent the influence to the hand-arm system when using the tool. An influence to the hand- arm system when using the tool will for example depend on the gripping force, the contact pressure force, the working direction, the adjustment of energy supply, the workpiece, and the workpiece support.

• The declared vibration total value has been measured by a standard test method and may be used for comparing one tool with another.
• It may also be used in a preliminary assessment of exposure.

WARNING

• The vibration emission during actual use of the power tool can differ from the declared total value depending on how the tool is used.
• 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).

NOTE
Due to HiKOKI’s continuing program of research and development, the specifications herein are subject to change without prior notice.
