Personal safety 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 influence 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. Protective equipment such as a dust mask, nonskid safety shoes, hard hat or hearing protection used for appropriate conditions will reduce personal injuries. c) Prevent unintentional starting. Ensure the switch is in the off-position before connecting to 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. d) 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. e) Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations. f) Dress properly. Do not wear loose clothing or jewellery. Keep your hair and clothing away from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts. g) If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Use of dust collection can reduce dust-related hazards. h) Do not let familiarity gained from frequent use of tools allow you to become complacent and ignore tool safety principles. A careless action can cause severe injury within a fraction of a second.
Power tool use and care a) 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. b) 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. c) Disconnect the plug from the power source and/or remove the battery pack, if detachable, 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. d) 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.

e) Maintain power tools and accessories. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tool’s operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools.
f) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
g) Use the power tool, accessories and tool bits etc. in accordance with 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.
h) Keep handles and grasping surfaces dry, clean and free from oil and grease. Slippery handles and grasping surfaces do not allow for safe handling and control of the tool in unexpected situations.
5) Battery tool use and care a) Recharge only with the charger specified 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. b) Use power tools only with specifically designated battery packs. Use of any other battery packs may create a risk of injury and fire. c) When 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 fire. d) Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact accidentally occurs, flush with water. If liquid contacts eyes, additionally seek medical help. Liquid ejected from the battery may cause irritation or burns. e) Do not use a battery pack or tool that is damaged or modified. Damaged or modified batteries may exhibit unpredictable behaviour resulting in fire, explosion or risk of injury. f) Do not expose a battery pack or tool to fire or excessive temperature. Exposure to fire or temperature above 130°C may cause explosion. g) Follow all charging instructions and do not charge the battery pack or tool outside the temperature range specified in the instructions. Charging improperly or at temperatures outside the specified range may damage the battery and increase the risk of fire.

CHAIN SAW SAFETY WARNINGS
1. Keep all parts of the body away from the saw chain when the chain saw is operating. Before you start the chain saw, make sure the saw chain is not contacting anything. A moment of inattention while operating chain saws may cause entanglement of your clothing or body with the saw chain.
2. Always hold the chain saw with your right hand on the rear handle and your left hand on the front handle. Holding the chain saw with a reversed hand configuration increases the risk of personal injury and should never be done.
3. Hold the chain saw by insulated gripping surfaces only, because the saw chain may contact hidden wiring. Saw chains contacting a “live” wire may make exposed metal parts of the chain saw “live” and could give the operator an electric shock.
4. Wear eye protection. Further protective equipment for hearing, head, hands, legs and feet is recommended. Adequate protective equipment will reduce personal injury from flying debris or accidental contact with the saw chain.
5. Do not operate a chain saw in a tree, on a ladder, from a rooftop, or any unstable support. Operation of a chain saw in this manner could result in serious personal injury.
6. Always keep proper footing and operate the chain saw only when standing on fixed, secure and level surface. Slippery or unstable surfaces may cause a loss of balance or control of the chain saw.
7. When cutting a limb that is under tension, be alert for spring back. When the tension in the wood fibres is released, the spring loaded limb may strike the operator and/or throw the chain saw out of control.
8. Use extreme caution when cutting brush and saplings. The slender material may catch the saw chain and be whipped toward you or pull you off balance.
9. Carry the chain saw by the front handle with the chain saw switched off and away from your body. When transporting or storing the chain saw, always fit the guide bar cover. Proper handling of the chain saw will reduce the likelihood of accidental contact with the moving saw chain.
10. Follow instructions for lubricating, chain tensioning and changing the bar and chain. Improperly tensioned or lubricated chain may either break or increase the chance for kickback.
11. Cut wood only. Do not use chain saw for purposes not intended. For example: do not use chain saw for cutting metal, plastic, masonry or non-wood building materials. Use of the chain saw for operations different than intended could result in a hazardous situation.
12. Do not attempt to fell a tree until you have an understanding of the risks and how to avoid them. Serious injury could occur to the operator or bystanders while felling a tree.

13. Follow all instructions when clearing jammed material, strong or servicing the chain saw. Make sure the swithch is off and the battery pack is removed. Unexpected actuation of the chain saw while clearing jammed material or servicing may result in serious personal injury.
Causes and operator prevention of kickback: (Fig. 2) Kickback may occur when the nose or tip of the guide bar touches an object, or when the wood closes in and pinches the saw chain in the cut. Tip contact in some cases may cause a sudden reverse reaction, kicking the guide bar up and back towards the operator. Pinching the saw chain along the top of the guide bar may push the guide bar rapidly back towards the operator. Either of these reactions may cause you to lose control of the saw which could result in serious personal injury. Do not rely exclusively upon the safety devices built into your saw. As a chain saw user, you should take several steps to keep your cutting jobs free from accident or injury. Kickback is the result of chain saw misuse and/or incorrect operating procedures or conditions and can be avoided by taking proper precautions as given below:
Maintain a firm grip, with thumbs and fingers encircling the chain saw handles, with both hands on the saw and position your body and arm to allow you to resist kickback forces. Kickback forces can be controlled by the operator, if proper precautions are taken. Do not let go of the chain saw.
Do not overreach and do not cut above shoulder height. This helps prevent unintended tip contact and enables better control of the chain saw in unexpected situations.
Only use replacement guide bars and saw chains specified by the manufacturer. Incorrect replacement guide bars and saw chains may cause chain breakage and/or kickback.
Follow the manufacturer’s sharpening and maintenance instructions for the saw chain. Decreasing the depth gauge height can lead to increased kickback.
ADDITIONAL SAFEY WARNINGS
1. Work without pressure. In addition, always keep your body warm.
2. Before commencing work, reflect fully on the work procedures involved and work to avoid accidents, otherwise injury may occur.
3. Do not use in the event of bad weather, such as strong wind, rain, snow, fog, or in areas prone to rockfall or avalanches. In bad weather, judgment may be impaired and the vibration may result in disaster.
4. When visibility is poor, such as during bad weather or night, do not use the unit. In addition, do not use it in rain or in a location exposed to rain. Unstable foothold or loss of balance may result in an accident.
5. Check the guide bar and saw chain before starting the unit.
If the guide bar or saw chain is cracked, or the product is scratched or bent, do not use the unit.
Check if the guide bar and saw chain are securely installed. If the guide bar or saw chain is broken or dislodged, this may result in an accident.
6. Before starting work, check to ensure the switch does not engage unless the lock-off button is pressed. If the unit does not working properly, immediately stop using and request repair from your HiKOKI Authorized Service Center.

7. Install the saw chain properly, in accordance with the instruction manual. If installed incorrectly, the saw chain will come off the guide bar and injury may occur.
8. Never remove any of the safety devices equipped on the chain saw (chain brake, lock-off button, chain catcher etc.). In addition, do not alter or immobilize them. Injury may occur.
9. In the following cases, switch the unit off and ensure the saw chain is no longer moving:
When not in use or being repaired. When shifting to a new work location. When inspecting, adjusting or replacing the saw chain,
guide bar, chain case and any other part. When refilling the chain oil. When removing dust etc. from the body. When removing obstacles, trash or sawdust generated
from work from the work area. When you take off the unit, or when you get away from
the unit. Otherwise, if you sense danger or anticipate risk.
If the saw chain is still moving, an accident may occur. 10. Work should generally be performed individually.
When multiple individuals are involved, ensure sufficient spacing between them. In particular, when felling standing trees or working on a slope, if you anticipate trees falling, rolling or sliding, ensure there is no danger to other workers. 11. Remain more than 15 m away from other people. In addition, when working with multiple persons, remain 15 m or more apart. There is a risk of impact with scatters and other accidents. Prepare a whistle alert etc. and determine appropriate contact method for other workers beforehand. 12. Before felling standing trees, ensure the following: Determine a safe evacuation location prior to felling. Remove obstacles (e.g., branches, shrubs) in advance. Based on a comprehensive evaluation of the state of the tree to be felled (e.g., trunk bend, tension of branches) and the surrounding situation (e.g., state of adjacent trees, presence of obstacles, terrain, wind), decide on the direction in which the standing tree will fall and then plan the felling procedure. Careless felling may result in injury. 13. When felling standing trees, ensure the following: During work, be very careful of the direction in which trees fall. When working on a slope, ensuring the tree will not roll, always work from the uphill side of the terrain. When the tree starts falling, switch the unit off, alert the surroundings, and immediately retreat to a safe location. During work, if the saw chain or guide bar become entangled in the tree, switch off and use a wedge. 14. During use, if the unit performance deteriorates, or you notice any abnormal sound or vibration, immediately switch off and discontinue use, and return to your HiKOKI Authorized Service Center for inspection or repair. If you continue using, injury may occur. 15. If the unit is accidentally dropped or exposed to impact, inspect carefully for damage or cracks and ensure there is no deformation. If the unit is damaged, cracked or deformed, injury may occur. 16. When transporting the unit by car, secure the unit to prevent it moving. There is a risk of accident.

17. Do not switch the unit on while the chain case is attached. Injury may occur.
18. Ensure there are no nails and other foreign objects in the material. If the saw chain impact on the nail etc., injury may occur.
19. To avoid the guide bar becoming entangled with the material when chopping on a verge or when subject to the weight of material while cutting, install a supporting platform close to the cutting position. If the guide bar becomes entangled, injury may occur.
20. If the unit is to be transported or stored after use, either remove the saw chain, or attach the chain case. If the saw chain comes into contact with your body, injury may occur.
21. Adequately care for the unit. To ensure work can be performed safely and efficiently,
care for the saw chain to ensure it provides optimal cutting performance. When replacing the saw chain or guide bar, maintaining the body, filling oil etc., follow the instruction manual. 22.

Removing the saw chain and guide bar (Fig. 7) Rotate the tension dial in the “-” direction to introduce a small amount of slack in the saw chain, then detach from the sprocket. Detach along with the guide bar in the direction indicated by the arrow. 3. Engaging the new saw chain in the sprocket (Fig. 8) Attach the saw chain from the guide bar tip. Make sure the saw chain is oriented so that the blade faces in the direction shown in the illustration below the sprocket. Insert the bolt and chain tensioner boss into the hole in the guide bar while holding the chain and guide bar tip. Engage the end of the saw chain to the sprocket and mount the guide bar to the saw body. 4. Installing the side cover (Fig. 9) Attach the side cover by inserting the lug into the slot in the saw body. Make sure the saw chain does not come loose from the guide bar. Rotate the knob once to temporarily fix it. Remove any dirt around the side cover before reattaching. 5. Adjusting the saw chain tension (Fig. 10) While lifting the guide bar tip, turn the tension dial to adjust the saw chain tension. Turn the tension dial to the “+” to increase the saw chain tension, and to the “-” to decrease it. 6. Checking the saw chain tension (Fig. 11) Adjust the saw chain tension so that the gap between the saw chain drive link and the guide bar is 0.5 to 1 mm when you lift the saw chain slightly near the center of the guide bar. 7. Securing the knob (Fig. 12) When adjustment is complete, lift up the guide bar, and fully tighten the knob.

INSPECTION AND PREPARATION
PRIOR TO USE
Prior to use, make the following inspection and preparation. WARNING To prevent accidents, always perform steps 1 to 3
ensuring the storage battery is removed from the body. Do not secure the lock- off button while it is pressed.
If the switch is accidentally engaged, the unit may unexpectedly start and injury may occur. 1. Ensuring the switch is off If you insert the storage battery without knowing whether the switch is engaged, the unit may unexpectedly start, which may result in an accident. When the switch is engaged while pressing the lockoff button, the unit switches on, and when the switch is released, the unit switches off. 2. Checking the saw chain tension If the saw chain tension is incorrect, there is a risk of damage to the saw chain or guide bar and malfunction. Referring to steps 5 to 7 “Installing (replacing) saw chain,” ensure an appropriate tension is set. While the saw chain is still new, it is particularly stretchy, so periodically check the tension and adjust as required. Also check the knob is securely tightened. 3. Checking the chain oil This unit is delivered without chain oil inside. Ensure the oil tank is filled with the chain oil provided before use. (Fig. 13) Periodically check the oil sight glass during work and replenish oil as required. If the chain oil supplied runs out, use HiKOKI chain oil sold separately or equivalent chain oil on the market. The chain oil lubricates automatically. The discharge rate for auto lubrication is factory preset to the maximum. To reduce the discharge rate, turn the oil pump adjuster on the right side of the oil sight glass clockwise. (Fig. 14) NOTE The oil tank capacity is about 100 ml. Make sure no oil leaks or overflows from the oil tank when replenishing the chain oil. We recommend that you stock up with chain oil. If you continue working without chain oil, the saw chain may burn through, or the motor may fail. Be careful to avoid dust or other foreign matter from entering the oil tank. If dust and other foreign matter enter the oil tank, the unit may fail. Chain oil left in the tank may leak due to the structure of this unit. Although this does not indicate a malfunction, it may soil the storage location, so be careful. When storing, empty the oil from the oil tank, and place an item under the main body which can absorb any leaks. 4. Installing the storage battery (Fig. 4) As shown in Fig. 4, push firmly until it clicks into place. CAUTION Securely attach the storage battery. If the storage battery is not securely attached, it may come off and injury may occur.

5. Checking operation of chain brake (Fig. 15) WARNING Although the chain brake is an emergency stop device,
this is not completely reliable. Operate carefully to avoid the risk of kickback. The chain brake is intended for use in emergencies and when starting up. Do not use it indiscriminately. To avoid impaired movement of the chain brake due to buildup of sawdust etc., clean regularly. The chain brake is an important component to ensure safe use. If you have any concern regarding the chain brake operation, request repair from your HiKOKI Authorized Service Center.
The chain brake is an emergency stop device that stops the saw chain when the unit is subject to kickback etc., to reduce risk. (Refer to “Causes and operator prevention of kickback.”) Push the chain brake ( ) in the direction indicated by the arrow to apply the chain brake and stop the saw chain. To release the chain brake, release the switch and pull back on the chain brake. CAUTION
The chain brake functions only when power is turned on. Check chain brake function in a location with no people or obstructions nearby. Press the switch while pressing the lock-off button. Once the saw chain begins turning, push the chain brake forward toward the saw chain. If the saw chain stops, the chain brake is functioning as it should. To release the brake, release the switch and pull back on the chain brake. 6. Checking chain oil discharge (Fig. 16) When switching the unit on, chain oil automatically lubricates the saw chain and guide bar. If oil does not seem to emerge 2 to 3 minutes after the unit starts, check if any sawdust has accumulated around the oil spout. (Refer to “Cleaning the chain oil spout.”) (Refer to “Checking the chain oil.”)

REMAINING BATTERY INDICATOR

You can check the battery’s remaining capacity by pressing the remaining battery indicator switch to light the indicator lamp. (Fig. 17, Table 1) The indicator will shut off approximately 3 seconds after the remaining battery indicator switch is pressed. It is best to use the remaining battery indicator as a guide since there are slight differences such as ambient temperature and the condition of the battery. Also, the remaining battery indicator may vary from those equipped to a tool or charger (Battery is not included, sold separately).

battery indicator lamp lights while pressing the remaining battery indicator switch.
CUTTING PROCEDURES
WARNING Prior to operation, ensure that chain brake works. During use, grip the handle securely with both hands. When cutting timber from the bottom, ensure the saw
chain does not impact with the timber. If the unit is pushed back, injury may occur. During work breaks or after work, always switch the unit off, and remove the storage battery from the main body.
Always monitor the workplace and surrounding area, ensure there are no objects which could cause injuries, accidents or failure, and if any are present, remove them in advance. In particular, when establishing a foothold for working, ensure there is no instability or any object which could be tripped over. When felling standing trees, always pay careful attention to the direction in which the tree will fall or roll, and determine a safe evacuation area and escape route for yourself in advance.
Ensuring the unit is switched off If the storage battery is inserted while the switch is unknowingly engaged, the unit may unexpectedly start, which may result in an accident. Installing the storage battery (Fig. 4) As shown in Fig. 4, push firmly until it clicks into place. Engaging the switch Ensuring the saw chain is not in contact with the timber, engage the switch, and start cutting when the saw chain speed has increased. CAUTION When switching the unit on, ensure the saw chain does not contact with material or anything else. During use, be careful to ensure the saw chain does not contact with other material or object. In particular, when you have finished cutting, be careful to ensure it does not touch the ground. NOTE Refill the oil tank early to prevent the unit running out of oil.

Precaution for cutting work

Do not cut all the way thorough the wood by starting from the bottom since there is the danger of the guide bar flying up out of control when the cut is finished.
Always prevent the operating chain saw from touching the ground or wire fences.
2. Branch cutting (1) Cutting branches from a standing tree:
A thick branch should initially be cut off at a point away from the trunk of the tree. First cut in about one third of the way from below, and then cut off the branch from above. Finally, cut off the remaining portion of the branch even with the trunk of the tree. (Fig. 22) CAUTION Always be careful to avoid falling branches. Always be alert for chain saw recoil. (2) Cutting branches from fallen trees: First cut off branches that do not touch the ground, then cut off those which touch the ground. When cutting thick branches that touch the ground, first cut in about half of the way from above, then cut the branch off from below. (Fig. 23) CAUTION

For large-scale operation or non-stop work This tool comes with an over-heat protection circuit that protects the electronic parts that control the rechargeable battery. During sustained use or during operations under high loads generated by pressure against the tool, tool temperature will rise and eventually trigger the over-heat protection circuit, which will shut down the tool. If this happens, let the tool cool for a length of time. When the temperature drops, it will again become possible to use the tool. When the rechargeable battery has to be exchanged during continuous operation, let the tool rest for about 15 minutes.
Gripping/pushing force of chain saw Always grip the chain saw securely. In addition, do not force the chain saw more than necessary. When cutting, additional force exerted on the chain saw will not accelerate the cutting speed. This will strain the motor, impair the performance, and damage or cause malfunction of the motor or guide bar. Use the unit in the range where the saw chain is at a reasonable speed.

When cutting off branches which touch the ground, be careful that the guide bar does not become bound by pressure.
During the final cutting stage, beware of the log suddenly rolling.
3. Log cutting When cutting a log positioned as shown in Fig. 24, first cut in about one third of the way from below, then cut down all the way from above. When cutting a log that

When the sharpness of saw chains deteriorates, the motor and each part of the body are burdened and the efficiency declines. For optimal performance of the unit, frequent maintenance is necessary to keep the saw chain sharp. 1. Blade sharpening
Use a 4 mm diameter round file. The round file should be held against the chain blade so that one-fifth of its diameter extends above the top of the blade, as shown in Fig. 29. Sharpen the blades by keeping the round file at a 30° angle in relation to the guide bar, as shown in Fig. 30. File the blades by gently pushing the round file in the direction of the grip. Make sure the round file does not touch the saw chain when drawing back the file. Ensure that all saw blades are filed at the same angle, or the cutting efficiency of the tool will be impaired. Appropriate angles for sharpening the blades correctly are shown in Fig. 31. (Round file is sold separately.) 2. Adjustment of depth gauge WARNING Do not sand the top part of the bumper tie strap and bumper drive link, nor cause the shape of said parts to deform. Adjustment of depth gauges must be in line with the predetermined dimensions and shapes, otherwise the risk of kickback may increase, causing an injury.

Bumper tie strap

Bumper drive link

Depth gauges shall be all lined up in the same manner because they are used to adjust depth at the position where the cutter inlays into the wood. When sharpening the saw chain, be sure to check the depth gauge every two or three times. (Fig. 32) Place a depth gauge jointer on the saw chain, leave the gauge visible at the groove, and use a flat file to bevel the portion out of the depth gauge jointer. (Fig. 33) (Depth gauge jointer and flat file are sold separately.) After filing away the depth gauge, round off the front side of the depth gauge as it was. (Fig. 34) After sharpening the saw chain, place it into chain oil to wash off the filings. If filings are not cleaned off, the saw chain and guide bar will quickly wear while in use. The depth gauge jointer can also be used when dressing with a round file. (Fig. 35)
MAINTENANCE AND INSPECTION
After operation, perform inspection and maintenance of each part when storing the unit. WARNING
During maintenance and inspection, always switch off the unit and remove the storage battery from the main body. In addition, disconnect the power plug of the charger from the outlet. CAUTION Always wear thick gloves when handling the saw chain. 1. Inspection of saw chains Occasionally inspect the saw chain. In the event of any abnormality, replace it with a new one referring to “Installing (replacing) saw chain” . Inspect the chain tension and check If it is correctly tightened.

Stop using the unit when the saw chain becomes blunt and sharpen it referring to “Sharpening of the chain blade”.
After use, carefully lubricate the saw chain and guide bars with oil for rust- proofing.
NOTE When cleaning the side cover, sprocket, chain oil spout, and guide bar, see the procedure “Installing (replacing) saw chain” and remove the saw chain.
2. Cleaning the side cover and sprocket (Fig. 36) Clean and remove any swarf or dust left inside the parts.
3. Cleaning the chain oil spout (Fig. 37) Before cleaning the chain oil spout, remove the side cover and guide bar.
4. Cleaning the guide bar (Fig. 38) When sawdust and similar become clogged in the groove of the guide bar or oil spout, the oil may not flow, which may result in the unit failing. Remove the guide bar and clean any sawdust clogged in the groove after use and when replacing the saw chain. (Refer to “Installing (replacing) saw chain.”)
5. Cleaning the chain brake (Fig. 39) Use a brush to remove any swarf from the gap to the saw body.
6. Inspecting the chain catcher (Fig. 40) The chain catcher is designed to protect the operator from being struck by the saw chain if the chain comes loose or is severed. The chain catcher is integrated into the side cover. Check to confirm that the chain catcher is not damaged.
7. 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 hazard.
8. 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.
9. Cleaning the battery installation compartment and the battery (Fig. 41) Use a brush or air blow gun to remove any swarf or dust and keep the saw clean.
NOTE Allowing swarf and dust to build up during use may
cause the storage battery to fall off or other accidents. Allowing swarf and dust to build up can also result in malfunctions, including faulty contact between the battery and the terminals. After cleaning, check to confirm that the storage battery can be easily detached and reattached to the tool body. 10. Cleaning of the outside When the chain saw 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. 11. Storage Clean all parts thoroughly. Coat metal parts with a thin layer of corrosion inhibitor. Be sure to repair any damaged areas before storing. When storing the unit, perform cleaning and maintenance of each part and mount the chain case to the guide bar. Store the chain saw in a place where 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.

16

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.

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

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 modified (such as disassembly and replacement of cells or other internal parts).
