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 fi nger 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.

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 toolʼs 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. 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.

GENERAL POWER TOOL SAFETY

WARNINGS 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.

5) Battery tool use and care

a) 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 fi re when used with another battery pack. b) 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. 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 fi re. d) Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact accidentally occurs, fl ush 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 modifi ed. Damaged or modifi ed batteries may exhibit unpredictable behaviour resulting in fi re, explosion or risk of injury. f) Do not expose a battery pack or tool to fi re or excessive temperature. Exposure to fi re 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 specifi ed in the instructions. Charging improperly or at temperatures outside the specifi ed range may damage the battery and increase the risk of fi re.

a) 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. b) Never service damaged battery packs. Service of battery packs should only be performed by the manufacturer or authorized service providers. 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 CIRCULAR SAW SAFETY

WARNINGS Cutting procedures

DANGER: Keep hands away from cutting area

and the blade. Keep your second hand on 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 cut and reduces the chance of blade binding. g) Always use blades with correct size and shape (diamond versus round) of arbour holes. Blades that do not match the mounting hardware of the saw will run off -centre, causing loss of control. h) Never use damaged or incorrect blade washers or bolt. 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 backwards, but kickback forces can be controlled by the operator, if proper precautions are taken. b) When 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, centre 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 kickback from the workpiece as the saw is restarted. d) Support large panels to minimise 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. 0000BookC18DSL.indb30000BookC18DSL.indb3 2019/02/2215:06:542019/02/2215:06:544 English 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 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. 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 bench or fl oor. An unprotected, coasting blade will cause the saw to walk backwards, cutting whatever is in its path. Be aware of the time it takes for the blade to stop after switch is released.

ADDITIONAL SAFETY WARNINGS

1. Always charge the battery at a temperature of

0°C – 40°C. A temperature of less than 0°C will result in over charging which is dangerous. The battery cannot be charged at a temperature higher than 40°C. The most suitable temperature for charging is that of 20°C – 25°C.

upward or to the side.

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

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

23. Since the saw blade will extend beyond the lower surface

of the lumber, place the lumber on a workbench when cutting. If a square block is utilized as a workbench, select level ground to ensure it is properly stabilized. An unstable workbench will result in hazardous operation. (Fig.3) To avoid possible accident, always ensure that the portion of lumber remaining after cutting is securely anchored or held in position.

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. Do not fi x and secure the switch lock. Besides, keep

your fi nger off the switch trigger when the circular saw is being carried around. Otherwise, the main body switch can be inadvertently turned ON, resulting in unexpected accidents.

26. Prior to cutting operation, make sure the material you

are going to cut. If the material to be cut is expected to generate harmful / toxic dusts, make sure the dust bag or appropriate dust extraction system is connected with dust outlet tightly. Wear the dust mask additionally, if available.

27. Before starting to saw, ensure that the saw blade has

reached full speed revolution.

28. Should the saw blade be stopped or made an abnormal

noise during operation, turn off the switch immediately.

29. Twisting and forcibly pressing the saw during cutting can

result in unreasonable pressure on the motor, so try to go straight quietly.

30. Avoid cutting operation in a state where the base bottom

is afl oat from the material being cut. Otherwise, the motor can get locked.

31. Preparing and checking the work environment. Make

sure that the work site meets all the conditions laid forth in the precautions.

32. Make sure that the battery is installed fi rmly. If it is as all

loose it could come off and cause an accident.

34. After having attached the saw blade, reconfi rm that the

lock lever is fi rmly secured in the prescribed position.

35. If the left-hand bolt is worked using other tools than

the provided box wrench, excessive tightening and insuffi cient tightening may take place resulting in injury.

36. After adjusting cutting depth, make sure to securely

tighten the butterfl y nut. Failure to do so may result in injury. (Fig.4)

37. After adjusting the angle of inclination, make sure to

securely tighten the butterfl y nut. Failure to do so may result in injury. (Fig.5) 0000BookC18DSL.indb40000BookC18DSL.indb4 2019/02/2215:06:542019/02/2215:06:545 English

38. Values of the inclined gauge provided on the base merely

serve as a rough guideline. For cutting operation at an inclined posture, use the circular saw after adjusting the angle between the base and the saw blade with a protractor, etc.

39. Pull out battery before carrying out any adjustment,

servicing or maintenance.

40. Ensure that the switch is in the OFF position. If the battery

installed to power tool while the switch is in the ON position, the power tool will start operating immediately, which could cause a serious accident.

41. If the main body is left as it is with the battery inserted,

there can be a case where the [switch lock] touches the fl oor and/or wall surface and lights up continuously, depending on the direction of the body. Be careful, since continuous lighting can easily make a full-charged battery go dead.

42. 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. 11).

43. Keep the light ON during cutting operation only. If

it is lit ON in other cases, the main body switch can be inadvertently turned ON, resulting in unexpected accidents.

44. Immediately after the light is turned OFF, the bulb retains

high temperature. Make sure to cool down the light bulb thoroughly before replacing it so as to prevent burns.

45. When replacing the light bulb, check the shape of base

as well as the rating (12 V, 5 W), and then carry out perfect mounting. Otherwise, the light bulb can come off and/or cause overheat.

MAINTENANCE AND INSPECTION

1. Inspecting the saw blade

Since use of as dull saw blade will degrade effi ciency and cause possible motor malfunction, sharpen or replace the saw blade as soon as abrasion is noted. CAUTION If a dull saw blade is used, reactive force is increased during cutting operation. Avoid the use of the dull saw blade without repair.

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 hazard.

3. Motor unit maintenance

The motor winding is an important part of this tool. Avoid damaging 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. 17). Dust or particle accumulation in the motor can result in damage.

4. 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. 17). Doing so is eff ective 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. Ensure smooth movement of lower guard Rotation part of the lower guard Housing vent Space between lower guard and gear cover Air gun Fig. 17

5. Adjusting the base and saw blade to maintain

perpendicularity The angle between the base and the saw blade has been adjusted to 90°, however should this perpendicularity be lost for some reason, adjust in the following manner: (1) Turn the base face up (Fig. 15) and loosen the wing-bolt. (2) Apply a square to the base and the saw blade and turning the slotted set screw with a slotted-head screwdriver, shift the position of the base to produce the desired right angle.

Dust may be removed with a clean rag or a cloth dampened with soapy water. Do not use bleach, chlorine, gasoline or thinner, for they may damage the plastics.

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. 0000BookC18DSL.indb80000BookC18DSL.indb8 2019/02/2215:06:542019/02/2215:06:549 English
