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.

1. Work area safety
   a) Keep the 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 flammable liquids, gases, or dust.
   Power tools create sparks that may ignite 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 the 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.
   The 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.
   The use of an RCD reduces the risk of electric shock

3. 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 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.
   Protective equipment such as a dust mask, non-skid 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 a power source and/or battery pack, picking up or carrying the tool.
   Carrying power tools with your fi nger on the switch or energizing 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 jewelry. Keep your hair and clothing away from moving parts.
   Loose clothes, jewelry, 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.
   The 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.

4. 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 aff ect the power tool 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 diff erent from those intended could result in a hazardous situation.

CORDLESS CIRCULAR SAW SAFETY WARNINGS

Cutting procedures
DANGER: Keep hands away from the cutting area and the blade. Keep your second hand on the auxiliary handle, or motor housing.
If both hands are holding the saw, they cannot be cut by the blade.
b) Do not reach underneath the workpiece.
The guard cannot protect you from the blade below the workpiece.
c) Adjust the cutting depth to the thickness of the workpiece.
Less than a full tooth of the blade teeth should be visible below the workpiece.
d) Never hold the workpiece in your hands or across your leg while cutting. Secure the workpiece to a stable platform.
It is important to support the work properly to minimize body exposure, blade binding, or loss of control.
e) Hold the power tool by insulated gripping surfaces, when performing an operation where the cutting tool may contact hidden wiring or its own cord.
Contact with a “live” wire will also make exposed metal parts of the power tool “live” and could give the operator an electric shock.
f) When ripping, always use a rip fence or straight edge guide.
This improves the accuracy of the cut and reduces the chance of blade binding.
g) Always use blades with the correct size and shape (diamond versus round) of arbor holes.
Blades that do not match the mounting hardware of the saw will run off -center, causing a loss of control.
h) Never use damaged or incorrect blade washers or bolts.
The blade washers and bolt were specially designed for your saw, for optimum performance and safety of operation.

Kickback causes and related warnings

• kickback is a sudden reaction to a pinched, jammed or misaligned saw blade, causing an uncontrolled saw to lift up and out of the workpiece toward the operator;
• when the blade is pinched or jammed tightly by the kerf closing down, the blade stalls and the motor reaction drives the unit rapidly back toward the operator;
• if the blade becomes twisted or misaligned in the cut, the teeth at the back edge of the blade can dig into the top surface of the wood causing the blade to climb out of the kerf and jump back toward the operator. Kickback is the result of saw misuse and/or incorrect operating procedures or conditions and can be avoided by taking proper precautions as given below.

a) Maintain a fi rm grip with both hands on the saw and position your arms to resist kickback forces.
Position your body to either side of the blade, but not in line with the blade.
Kickback could cause the saw to jump backward, but kickback forces can be controlled by the operator, if proper precautions are taken.
b) When the blade is binding, or when interrupting a cut for any reason, release the trigger and hold the saw motionless in the material until the blade comes to a complete stop.
Never attempt to remove the saw from the work or pull the saw backward while the blade is in motion or kickback may occur.
Investigate and take corrective actions to eliminate the cause of blade binding.
c) When restarting a saw in the workpiece, center the saw blade in the kerf so that the saw teeth are not engaged into the material.
If a saw blade binds, it may walk up or kick back from the workpiece as the saw is restarted.
d) Support large panels to minimize the risk of blade pinching and kickback.
Large panels tend to sag under their own weight.
Supports must be placed under the panel on both sides, near the line of cut, and near the edge of the panel.
e) Do not use dull or damaged blades.
Unsharpened or improperly set blades produce narrow kerf causing excessive friction, blade binding, and kickback.
f) Blade depth and bevel adjusting locking levers must be tight and secure before making the cut.
If blade adjustment shifts while cutting, it may cause binding and kickback.
g) Use extra caution when sawing into existing walls or other blind areas.
The protruding blade may cut objects that can cause kickback.

Lower guard function
a) Check the lower guard for proper closing before each use. Do not operate the saw if the lower guard does not move freely and close instantly. Never clamp or tie the lower guard into the open position. If the saw is accidentally dropped, the lower guard may be bent. Raise the lower guard with the retracting handle and make sure it moves freely and does not touch the blade or any other part, in all angles and depths of the cut.
b) Check the operation of the lower guard spring. If the guard and the spring are not operating properly, they must be serviced before use. The lower guard may operate sluggishly due to damaged parts, gummy deposits, or a build-up of debris.
c) The lower guard may be retracted manually only for special cuts such as “plunge cuts” and “compound cuts”. Raise the lower guard by the retracting handle and as soon as the blade enters the material, the lower guard must be released. For all other sawing, the lower guard should operate automatically.
d) Always observe that the lower guard is covering the blade before placing the saw down on a bench or fl poor. An unprotected, coasting blade will cause the saw to walk backward, cutting whatever is in its path. Be aware of the time it takes for the blade to stop after the switch is released.

ADDITIONAL SAFETY WARNINGS

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

2. Never disassemble the rechargeable battery and charger.

3. Never short-circuit the rechargeable battery. Shortcircuiting the battery will cause a great electric current and overheating. It results in burn or damage to the battery.

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

5. When using this unit continuously, the unit may overheat, leading to damage in the motor and switch. Please leave it without using it for approximately 15 minutes.

6. Do not insert objects into the air ventilation slots of the charger. Inserting metal objects or infl flammables into the charger air ventilation slots will result in an electrical shock hazard or a damaged charger.

7. Using an exhausted battery will damage the charger.

8. 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.

9. Wear earplugs to protect your ears during operation.

10. Use only blade diameter specifi ed on the machine.

11. Do not use any abrasive wheel.

12. Do not use saw blades that are deformed or cracked.

13. Do not use saw blades made of high-speed steel.

14. Do not use saw blades that do not comply with the characteristics specifi ed in these instructions.

15. Do not stop the saw blades by lateral pressure on the disc.

16. Always keep the saw blades sharp.

17. Ensure that the lower guard moves smoothly and freely.

18. Never use the circular saw with its lower guard fi fixed in the open position.

19. Ensure that the retraction mechanism of the guard system operates correctly.

20. Never operate the circular saw with the saw blade turned upward or to the side.

21. Ensure that the material is free of foreign matters such as nails.

22. The saw blades range should be from 165 mm to 162 mm.

23. Pull out the battery before carrying out any adjustment, servicing or maintenance.

24. Be careful of brake kickback. This circular saw features an electric brake that functions when the switch is released. As there is some kickback when the brake functions, be sure to hold the main body securely

25. Ensure that the switch is in the OFF position. If the battery is installed on the power tool while the switch is in the ON position, the power tool will start operating immediately, which could cause a serious accident.

26. Avoid cutting in the state where the base has fl rated up from the material. When the blade is binding, or when interrupting a cut for any reason, release the trigger and hold the saw motionless in the material until the blade comes to a complete stop. Never attempt to remove the saw from the work or pull the saw backward while the blade is in motion or KICKBACK may occur. Investigate and take corrective actions to eliminate the cause of blade binding.

27. Support large panels to minimize the risk of blade pinching and KICKBACK. Large panels tend to sag under their own weight (Fig. 3). Supports must be placed under the panel on both sides, near the line of cut and near the edge of the panel as shown in Fig. 2. To minimize the risk of blade pinching and kickback. When cutting operation requires the resting of the saw on the workpiece, the saw shall be rested on the larger portion and the smaller piece cut off.

28. Use extra caution when making a “Pocket Cut” into existing walls or other blind areas. The protruding blade may cut objects that can cause KICKBACK. NEVER place your hand or fi fingers behind the saw (Fig. 4). If kickback occurs, the saw could easily jump backward over your hand, possibly causing severe injury.

29. WARNING: It is important to support the workpiece properly and to hold the saw fi only to prevent loss of control which could cause personal injury. Fig. 5 illustrates the typical hand support of the saw.

30. Place the wider portion of the saw base on that part of the workpiece which is solidly supported, not on the section that will fall off when the cut is made. As an example, Fig. 6 illustrates the RIGHT way to cut off the end of the board, and Fig. 7 the WRONG way. If the workpiece is short or small, the clamp is down. DON’T TRY TO HOLD SHORT PLACES BY HAND!

31. Never attempt to saw with the circular saw held upside down in a vise. This is extremely dangerous and can lead to serious accidents (Fig. 8).

32. When using the guide, do not attempt an inclined cut which would allow the cut material to slip between the saw blade and guide. Doing so could result in injury. (Fig. 12)

33. Should the lever remain loosened, it will create a very hazardous situation. Always thoroughly clamp it. (Fig. 13)

34. It is very hazardous to allow the wing bolts to remain loosened. Always thoroughly clamp it. (Fig. 9)

35. Prior to the cutting operation, make sure the material you are going to cut. If the material to be cut is expected to generate harmful/toxic specks of dust, make sure the dust bag or appropriate dust extraction system is connected with the dust outlet tightly. Wear the dust mask additionally, if available.
    ○ Before starting to saw, confi rm that the saw blade has attained full-speed revolution.
    ○ Should the saw blade stop or make an abnormal noise while operating, promptly turn OFF the switch.
    ○ Using the circular saw with the saw blade facing upwards or sideways is very hazardous. Such uncommon applications should be avoided.
    ○ When cutting materials, always wear protective glasses.
    ○ When fi is finished with a job, pull out the battery.

36. After having attached the saw blade, reconfi rm that the lock lever is fi firmly secured in the prescribed position.

37. Do not use the product if the tool or the battery terminals (battery mount) are deformed. Installing the battery could cause a short circuit that could result in smoke emission or ignition

38. Keep the tool’s terminals (battery mount) free of swarf and dust.
    ○ Prior to use, make sure that swarf and dust have not collected in the area of the terminals.
    ○ During use, try to avoid swarf or dust on the tool from falling on the battery.
    ○ When suspending operation or after use, do not leave the tool in an area where it may be exposed to falling swarf or dust. Doing so could cause a short circuit that could result in smoke emission or ignition.

39. Always use the tool and battery at temperatures between -5°C and 40°C. 40. Use a saw blade that is for cutting wood.

40. Use a saw blade with a displayed speed that is equal to or higher than the rotation speed displayed on the tool

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 firmly 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 fi rst 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 or lights for 1 second, does not light for 0.5 seconds (off for 0.5 seconds). In such a case, fi first let the battery cool, then start charging.
• When the pilot lamp fl ickers in red (at 0.2-seconds intervals), check for and take out any foreign objects in the charger’s battery connector. If there are no foreign objects, it is probable that the battery or charger is malfunctioning. Take it to your authorized Service Center.
• Since the built-in microcomputer takes about 3 seconds to confi rm that the battery being charged with chargers are 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.

MAINTENANCE AND INSPECTION

1. Inspecting the saw blade Since use of a dull saw blade will degrade effi ciency and cause possible motor malfunction, sharpen or replace the saw blade as soon as abrasion is noted.

2. 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.

3. Inspecting the carbon brushes (Fig. 22) The motor employs carbon brushes which are consumable parts. Since an excessively worn carbon brush can result in motor trouble, replace the carbon brushes with new ones having the same carbon brush No. ⓐ shown in the fi gure when it becomes worn to or near the “wear limit” ⓑ. In addition, always keep carbon brushes clean and ensure that they slide freely within the brush holders.
   CAUTION
   When replacing the new carbon brushes, always use genuine HiKOKI carbon brushes with the number specifi ed in the drawing.

4. Replacing carbon brushes Disassemble the brush caps with a slotted-head screwdriver. The carbon brushes can then be easily removed.

5. Motor unit maintenance The motor winding is an important part of this tool. Avoid damage and be careful to avoid contact with cleaning oil or water. After 50 hours of use, clean the motor by blowing into the ventilation holes of the motor housing with dry air from an air gun or other tool (Fig. 25). Dust or particle accumulation in the motor can result in damage.

6. Inspecting and maintaining the lower guard Always make sure that the lower guard moves smoothly. In the event of any malfunction, immediately repair the lower guard. For cleaning and maintenance, use an air gun or other tool to blow clean the space between the lower guard and gear cover as well as the rotation part of the lower guard with dry air (Fig. 25). Doing so is eff active for the emission of chips or other particles. Accumulation of chips or other particles around the lower guard may result in malfunction or damage.
   WARNING
   To prevent dust inhalation or eye irritation, wear protective safety goggles and a dust mask when using an air gun or other tool to clean the lower guard, ventilation holes or other parts of the product.

7. Cleaning the inside of the saw cover Regularly check and clean to make sure that sawdust and other residue do not collect inside of the saw cover. Always remove the saw  blade when checking and cleaning.

8. Inspection of terminals (tool and battery)
   Check to make sure that swarf and dust have not been collected on the terminals.
   On occasion check prior, during, and after the operation.
   CAUTION
   Remove any swarf or dust which may have collected on the terminals.
   Failure to do so may result in malfunction.

9. 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.

10. Storage
    Storing in a place below 40°C and out of the 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.
