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.

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. Protective equipment such as a dust mask, non-skid safety shoes, hard hat or hearing protection used for appropriate conditions will reduce personal injuries. (Original instructions) 000BookG1812DAEU.indb6000BookG1812DAEU.indb6 2022/08/3015:34:292022/08/3015:34:297 English 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 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.

OFF OPERATIONS a) This power tool is intended to function as a grinder or cut-off tool. 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. b) Operations such as sanding, wire brushing, polishing or hole cutting are not recommended to be performed with this power tool. Operations for which the power tool was not designed may create a hazard and cause personal injury. c) Do not convert this power tool to operate in a way which is not specifi cally designed and specifi ed by the tool manufacturer. Such a conversion may result in a loss of control and cause serious personal injury. d) Do not use accessories which are not specifi cally designed and specifi ed by the tool manufacturer. Just because the accessory can be attached to your power tool, it does not ensure safe operation. e) The rated speed of the accessory must be at least equal to the maximum speed marked on the power tool. Accessories running faster than their rated speed can break and fl y apart. f) The outside diameter and the thickness of your accessory must be within the capacity rating of your power tool. Incorrectly sized accessories cannot be adequately guarded or controlled. g) The dimensions of the accessory mounting must fi t the dimensions of the mounting hardware of the power tool. Accessories that do not match the mounting hardware of the power tool will run out of balance, vibrate excessively and may cause loss of control. h) Do not use a damaged accessory. Before each use inspect the accessory such as abrasive wheels for chips and cracks, backing pad for cracks, tear or excess wear, wire brush for loose or cracked wires. If power tool or accessory is dropped, inspect for damage or install an undamaged accessory. After inspecting and installing an accessory, position yourself and bystanders away from the plane of the rotating accessory and run the power tool at maximum no-load speed for one minute. Damaged accessories will normally break apart during this test time.

i) Wear personal protective equipment. Depending

on application, use face shield, safety goggles or safety glasses. As appropriate, wear dust mask, hearing protectors, gloves and workshop apron capable of stopping small abrasive or workpiece fragments. The eye protection must be capable of stopping fl ying debris generated by various operations. The dust mask or respirator must be capable of fi ltrating particles generated by your operation. Prolonged exposure to high intensity noise may cause hearing loss. j) Keep bystanders a safe distance away from work area. Anyone entering the work area must wear personal protective equipment. Fragments of workpiece or of a broken accessory may fl y away and cause injury beyond immediate area of operation. k) Hold the power tool by insulated gripping surfaces only, when performing an operation where the cutting tool may contact hidden wiring. Contact with a “live” wire will also make exposed metal parts of the power tool “live” and could give the operator an electric shock. l) Position the cord clear of the spinning accessory. If you lose control, the cord may be cut or snagged and your hand or arm may be pulled into the spinning accessory. 000BookG1812DAEU.indb7000BookG1812DAEU.indb7 2022/08/3015:34:292022/08/3015:34:298 English m) Never lay the power tool down until the accessory has come to a complete stop. The spinning accessory may grab the surface and pull the power tool out of your control. n) Do not run the power tool while carrying it at your side. Accidental contact with the spinning accessory could snag your clothing, pulling the accessory into your body. o) Regularly clean the power tool’s air vents. The motor’s fan will draw the dust inside the housing and excessive accumulation of powdered metal may cause electrical hazards. p) Do not operate the power tool near fl ammable materials. Sparks could ignite these materials. q) Do not use accessories that require liquid coolants. Using water or other liquid coolants may result in electrocution or shock.

KICKBACK AND RELATED

WARNINGS Kickback is a sudden reaction to a pinched or snagged rotating wheel, backing pad, brush or any other accessory. Pinching or snagging causes rapid stalling of the rotating accessory which in turn causes the uncontrolled power tool to be forced in the direction opposite of the accessory’s rotation at the point of the binding. For example, if an abrasive wheel is snagged or pinched by the workpiece, the edge of the wheel that is entering into the pinch point can dig into the surface of the material causing the wheel to climb out or kick out. The wheel may either jump toward or away from the operator, depending on direction of the wheel’s movement at the point of pinching. Abrasive wheels may also break under these conditions. Kickback is the result of power tool 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 power tool and position your body and arm to allow you to resist kickback forces. Always use auxiliary handle, if provided, for maximum control over kickback or torque reaction during start-up. The operator can control torque reactions or kickback forces, if proper precautions are taken. b) Never place your hand near the rotating accessory. Accessory may kickback over your hand. c) Do not position your body in the area where power tool will move if kickback occurs. Kickback will propel the tool in direction opposite to the wheel’s movement at the point of snagging. d) Use special care when working corners, sharp edges etc. Avoid bouncing and snagging the accessory. Corners, sharp edges or bouncing have a tendency to snag the rotating accessory and cause loss of control or kickback. e) Do not attach a saw chain woodcarving blade, segmented diamond wheel with a peripheral gap greater than 10 mm or toothed saw blade. Such blades create frequent kickback and loss of control.

OFF OPERATIONS a) Use only wheel types that are specifi ed for your power tool and the specifi c guard designed for the selected wheel. Wheels for which the power tool was not designed cannot be adequately guarded and are unsafe. b) The grinding surface of centre depressed wheels must be mounted below the plane of the guard lip. An improperly mounted wheel that projects through the plane of the guard lip cannot be adequately protected. c) The guard must be securely attached to the power tool and positioned for maximum safety, so the least amount of wheel is exposed towards the operator. The guard helps to protect the operator from broken wheel fragments, accidental contact with wheel and sparks that could ignite clothing. d) Wheels must be used only for specifi ed applications. For example: do not grind with the side of cut-off wheel. Abrasive cut-off wheels are intended for peripheral grinding, side forces applied to these wheels may cause them to shatter. e) Always use undamaged wheel fl anges that are of correct size and shape for your selected wheel. Proper wheel fl anges support the wheel thus reducing the possibility of wheel breakage. Flanges for cut-off wheels may be diff erent from grinding wheel fl anges. f) Do not use worn down wheels from larger power tools. A wheel intended for larger power tool is not suitable for the higher speed of a smaller tool and may burst. g) When using dual purpose wheels always use the correct guard for the application being performed. Failure to use the correct guard may not provide the desired level of guarding, which could lead to serious injury.

OFF OPERATIONS a) Do not “jam” the cut-off wheel or apply excessive pressure. Do not attempt to make an excessive depth of cut. Overstressing the wheel increases the loading and susceptibility to twisting or binding of the wheel in the cut and the possibility of kickback or wheel breakage. b) Do not position your body in line with and behind the rotating wheel. When the wheel, at the point of operation, is moving away from your body, the possible kickback may propel the spinning wheel and the power tool directly at you. c) When the wheel is binding or when interrupting a cut for any reason, switch off the power tool and hold it motionless until the wheel comes to a complete stop. Never attempt to remove the cut- off wheel from the cut while the wheel is in motion otherwise kickback may occur. Investigate and take corrective action to eliminate the cause of wheel binding. d) Do not restart the cutting operation in the workpiece. Let the wheel reach full speed and carefully re-enter the cut. The wheel may bind, walk up or kickback if the power tool is restarted in the workpiece. 000BookG1812DAEU.indb8000BookG1812DAEU.indb8 2022/08/3015:34:292022/08/3015:34:299 English e) Support panels or any oversized workpiece to minimize the risk of wheel pinching and kickback. Large workpieces tend to sag under their own weight. Supports must be placed under the workpiece near the line of cut and near the edge of the workpiece on both sides of the wheel. f) Use extra caution making a “pocket cut” into existing walls or other blind areas. The protruding wheel may cut gas or water pipes, electrical wiring or objects that can cause kickback. g) Do not attempt to do curved cutting. Overstressing the wheel increases the loading and susceptibility to twisting or binding of the wheel in the cut and the possibility of kickback or wheel breakage, which can lead to serious injury.

– Attach the side handle fi rmly, hold the housing and the side handle with both hands, and support the tool body securely. (Fig. 2) – Check that speed marked on the wheel is equal to or greater than the rated speed of the grinder; – Ensure that the wheel dimensions are compatible with the grinder; – Inspect the grinding wheel before use, do not use chipped, cracked or otherwise defective products; – Ensure that mounted wheels and points are fi tted in accordance with the manufacturer’s instructions; – Ensure that blotters are used when they are provided with the bonded abrasive product and when they are required; – Ensure that the abrasive product is correctly mounted and tightened before use and run the tool at no-load for 30 seconds in a safe position, stop immediately if there is considerable vibration or if other defects are detected. If this condition occurs, check the machine to determine the cause; – If a guard is equipped with the tool never use the tool without such a guard; – Do not use separate reducing bushings or adapters to adapt large hole abrasive wheels; – For tools intended to be fi tted with threaded hole wheel, ensure that the thread in the wheel is long enough to accept the spindle length; – Do not use cutting off wheel for side grinding; – Ensure that sparks resulting from use do not create a hazard e.g. do not hit persons, or ignite fl ammable substances; – Ensure that ventilation openings are kept clear when working in dusty conditions, if it should become necessary to clear dust, fi rst disconnect the tool from the mains supply (use non metallic objects) and avoid damaging internal parts; – Always use eye and ear protection. Other personal protective equipment such as dust mask, gloves, helmet and apron should be worn; – Pay attention to the wheel that continues to rotate after the tool is switched off . – When using dual-purpose (combined grinding and cut- off wheels), use only the type A wheel guard. (See page 247) – When using a type A wheel guard for lateral grinding, the guard may interfere with the workpiece causing poor control. – When using a type B wheel guard for cutting-off operations with bonded cut-off wheels, there is an increased risk of exposure to emitted sparks and particles, as well as exposure to wheel fragments in the event of a wheel burst. – When using a type A, B wheel guard for cutting-off operations or lateral grinding in concrete or masonry, there is an increased risk of exposure to dust and loss of control resulting in kickback. – Do not use any segmented diamond cut-off wheels with segment slits >10 mm. Only negative segment cutting angles are permitted. – The workpiece must lay fl at and be secured against slipping, e.g. using clamps. Large workpieces must be suffi ciently supported. – Observe the specifi cations of the tool or accessory manufacturer. Protect wheels from grease or impact. – Accessories must be stored and handled with care in accordance with the manufacturer's instructions. WARNING – When using a cutting-off wheel, be sure to attach a type A wheel guard. – When using a grinding wheel, be sure to attach a type B wheel guard. – For safety reasons, only use the wheel guard provided for the respective accessory. Using an incorrect wheel guard can lead to loss of control and serious injuries. See also page 247.

*1 If the red lamp continues to blink even after the charger has been attached, check to confi rm that the battery has been fully inserted. *2 Although charging will start once the battery has cooled down even when left in situ, the best practice is to remove the battery and allow it to cool down in a shaded, well-ventilated location before charging.

○ Fully insert the battery. ○ Check to confi rm that no foreign matter is stuck to the battery mount or terminals. <If charging takes a long time> ○ Charging will take longer at extremely low ambient temperatures. Charge the battery in a warm location (such as indoors). ○ Do not block the air vent. Otherwise the interior will overheat, reducing the charger’s performance. ○ If the cooling fan is not operating, contact a HiKOKI Authorized Service Center for repairs. (2) Regarding the temperatures and charging time of the rechargeable battery The temperatures and charging time will become as shown in Table 2. Table 2 Model UC18YSL3 Type of battery Li-ion Charging voltage 14.4–18 V Temperatures at which the battery can be recharged 0°C–50°C Charging time, for battery capacity, approx. (At 20°C)

4. Disconnect the charger’s power cord from the

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 fi rst and second time. This is a temporary phenomenon, and 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. 000BookG1812DAEU.indb13000BookG1812DAEU.indb13 2022/08/3015:34:312022/08/3015:34:3114 English (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 charge indicator lamp of the charger lights for 0.3 seconds, does not light for 0.3 seconds (off for

0.3 seconds). In such a case, fi rst let the battery cool,

then start charging. ○ When the charge indicator lamp fl ickers (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, it is probable that the battery or charger is malfunctioning. Take it to your authorized Service Center. ○ Since the built-in micro computer takes about 3 seconds to confi rm that the battery being charged with UC18YSL3 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.

Selecting accessories ― 249 *1 sold separately *2 WARNING Before use, be sure to tighten the wheel nut with the included wrench. Failure to tighten could result in the wheel nut loosening when the brake is activated during a stop. NOTE The wheel washer is specifi cally for this product. Do not use it for any other product. *3 Grinding angle and grinding method Press down the machine evenly on the surface and move back and forth so that the surface of the workpiece does not become too hot. Rough grinding: position the machine at an angle of 15°–30° for the best working results. When the grinding stone is new, its corner may dig in when it is pushed forward, so pull back during use. (Fig. 10-a) Once the wheel edge is worn, the workpiece can be ground in both directions. (Fig. 10-b). *4 Cutting work Always work against the run of the disc. Otherwise there is the danger of the machine kicking back from the cut out of control. Guide the machine evenly at a speed suitable for the material being processed. Do not tilt, apply excessive force or sway from side to side.

MAINTENANCE AND INSPECTION

WARNING Be sure to turned off the switch and remove the battery before maintenance and inspection.

1. Inspecting the depressed center wheel

Ensure that the depressed center wheel is free of cracks and surface defects.

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. Filter cleaning and inspection (Fig. 12)

WARNING Wear protective glasses and a dust mask when cleaning the fi lter with an air gun. Failure to do so may result in inhalation or exposure of the eyes to debris or dust. After use, remove any debris or dust adhered to the fi lter using a soft brush. Check the fi lter periodically to ensure that it is free of scratching, chipping, or tearing. Replace with a new fi lter if the fi lter is damaged in any way. NOTE ○ If the mesh is clogged and the debris or dust cannot be removed, detach the fi lter and clean it with an air gun, etc. ○ After cleaning, make sure to securely attach the fi lter.

4. 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. NOTE In order to expel debris and dust, periodically run the motor with no load.

5. Inspection of terminals (tool and battery)

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

6. Cleaning on the outside

When the cordless disc grinder 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.

Store the power tool and battery in a place in which the temperature is less than 40°C and out of reach of children. 000BookG1812DAEU.indb14000BookG1812DAEU.indb14 2022/08/3015:34:312022/08/3015:34:3115 English NOTE Storing lithium-ion batteries. Make sure the lithium-ion batteries have been fully charged before storing them. Prolonged storage (3 months or more) of batteries with a low charge may result in performance deterioration, signifi cantly reducing battery usage time or rendering the batteries incapable of holding a charge. However, signifi cantly reduced battery usage time may be recovered by repeatedly charging and using the batteries two to fi ve times. If the battery usage time is extremely short despite repeated charging and use, consider the batteries dead and purchase new batteries. CAUTION In the operation and maintenance of power tools, the safety regulations and standards prescribed in each country must be observed. Important notice on the batteries for the HiKOKI cordless power tools Please always use one of our designated genuine batteries. We cannot guarantee the safety and performance of our cordless power tool when used with batteries other than these designated by us, or when the battery is disassembled and modifi ed (such as disassembly and replacement of cells or other internal parts). GUARANTEE We guarantee HiKOKI Power Tools in accordance with statutory/country specifi c 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. Information concerning airborne noise and vibration The measured values were determined according to EN60745 and declared in accordance with ISO 4871. Measured A-weighted sound power level: 96 dB (A) Measured A-weighted sound pressure level: 85 dB (A) Uncertainty K: 3 dB (A). Wear hearing protection. Vibration total values (triax vector sum) determined according to EN60745. Sanding steel plate: Vibration emission value a

The declared vibration total value and the declared noise emission value have been measured in accordance with a standard test method and may be used for comparing one tool with another. They may also be used in a preliminary assessment of exposure. WARNING ○ The vibration and noise emission during actual use of the power tool can diff er from the declared total value depending on the ways in which the tool is used especially what kind of workpiece is processed; and ○ Identify safety measures to protect the operator that are based on an estimation of exposure in the actual conditions of use (taking account of all parts of the operating cycle such as the times when the tool is switched off and when it is running idle in addition to the trigger time). ○ The grinding thin sheets of metal or other easily vibrating structures with a large surface can result in a total emission much higher (up to 15 dB) than the declared noise emission values. Such workpieces should as far as possible be prevented from emitting sound by suitable measures such as the application of heavy fl exible damping mats. The increased noise emission is also to be considered for both the risk assessment of noise exposure and selecting adequate heating protection.
