USER MANUAL C18DMR HiKOKI

WARNING Read all safety warnings and all instructions. Failure to follow the warnings and instructions may result in electric shock, fire 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 flammable 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. Unmodified 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 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 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 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, clothing and gloves 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.

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 the battery pack from the power tool before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally. 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. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tools 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. (Original instructions) 01Eng_C18DMR_DL_WE 7/1/13, 10:36 AM89 English

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.

a) Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained. PRECAUTION Keep children and infirm persons away. When not in use, tools should be stored out of reach of children and infirm persons.

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 piece being cut in your hands or across your leg. 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 only, 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 eccentrically, 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, bound 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 bound 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 firm 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 and check that saw teeth are not engaged into the material. If saw blade is binding, 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. f) Blade depth and bevel adjusting locking levers must be tight and secure before making 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. 01Eng_C18DMR_DL_WE 7/1/13, 10:36 AM910 English Lower guard function a) Check lower guard for proper closing before each use. Do not operate the saw if lower guard does not move freely and close instantly. Never clamp or tie the lower guard into the open position. If saw is accidentally dropped, 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) Lower guard may be retracted manually only for special cuts such as “plunge cuts” and “compound cuts”. Raise lower guard by retracting handle and as soon as 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 saw down on bench or floor. 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.

1. Always charge the battery at a temperature of 10

– 40°C. A temperature of less than 10°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 – 25°C.

2. When one charging is completed, leave the charger

for about 15 minutes before the next charging of battery. Do not charge more than two batteries consecutively.

3. Do not allow foreign matter to enter the hole for

connecting the rechargeable battery.

4. Never disassemble the rechargeable battery and

5. Never short-circuit the rechargeable battery. Short-

circuiting the battery will cause a great electric current and overheat. It results in burn or damage to the battery.

6. Do not dispose of the battery in fire.

If the battery is burnt, it may explode.

7. 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.

8. Do not insert object into the air ventilation slots

of the charger. Inserting metal objects or inflammables into the charger air ventilation slots will result in electrical shock hazard or damaged charger.

9. Using an exhausted battery will damage the

10. 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.

11. Wear earplugs to protect your ears during

Otherwise the counterforce produced may result in inaccurate and even dangerous operation.

13. Do not use saw blades which are deformed or

14. Do not use saw blades made of high speed steel.

15. Do not use saw blades which do not comply with

the characteristics specified in these instructions.

16. Do not stop the saw blades by lateral pressure

17. Always keep the saw blades sharp.

18. Ensure that the lower guard moves smoothly and

19. Never use the circular saw with its lower guard

fixed in the open position.

20. Ensure that the retraction mechanism of the guard

system operates correctly.

21. The saw blades body must be thinner than the

riving knife and the width of cut, or kerf (with teeth set) must be greater than the thickness of the riving knife.

22. Never operate the circular saw with the saw blade

turned upward or the side.

23. Ensure that the material is free of foreign matters

24. The riving knife should always be used except

when plunging in the middle of the workpiece.

25. The saw blades range should be from 165 mm

26. 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.

27. Avoid cutting in the state where the base has

floated up from the material. 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.

28. 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 as shown in Fig. 1. To minimize the risk of blade pinching and kickback. When cutting operation requires the resting of the saw on the work piece, the saw shall be rested on the larger portion and the smaller piece cut off.

Actual charge time may vary. “x” Indicates that the battery pack is not compatible with that specific charger. NEVER place your hand or fingers behind the saw (Fig. 3). If kickback occurs, the saw could easily jump backwards over your hand, possibly causing severe injury.

30. WARNING: It is important to support the work

piece properly and to hold the saw firmly to prevent loss of control which could cause personal injury. Fig. 4 illustrates typical hand support of the saw.

31. Place the wider portion of the saw base on that

part of the work piece which is solidly supported, not on the section that will fall off when the cut is made. As examples, Fig. 5 illustrates the RIGHT way to cut off the end of board, and Fig. 6 the WRONG way. If the work piece is short or small, clamp is down. DON’T TRY TO HOLD SHORT PLACES BY HAND!

32. 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. 7).

33. When the brake becomes ineffective, replace the

carbon brushes with new ones.

CAUTION ON LITHIUM-ION BATTERY

To extend the lifetime, the lithium-ion battery equips with the protection function to stop the output. In the cases of 1 and 2 described below, when using this product, even if you are pulling the switch, the motor may stop. This is not the trouble but the result of protection function.

1. When the battery power remaining runs out (The

battery voltage drops to about 12V (C18DL)), the motor stops. In such case, charge it up immediately.

5. Hold the charger firmly and pull out the battery

NOTE Be sure to pull out the battery from the charger after use, and then keep it. CAUTION 䡬 If the battery is charged while it is heated because it has been left for a long time in a location subject to direct sunlight or because the battery has just been used, the pilot lamp of the charger lights up green. In such a case, first let the battery cool, then start charging. 䡬 When the pilot lamp flikers in red quickly (at 0.2- second intervals), check for and take out any foreign objects in the charger’s battery installation hole. If there are no foreign objects, it is probable that the battery or charger is malfunctioning. Take it to your Authorized Service Center. 䡬 Since the built-in micro computer takes about 3 seconds to confirm that the battery being charged with UC24YFA and UC18YRL are taken out, wait for Charger

Rechargeable batteries Ni-Cd batteries –5°C – 55°C Ni-MH batteries 0°C – 45°C –5°C – 50°C Li-ion batteries x 0°C – 50°C 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. 〈UC18YG〉 Before using the power tool, charge the battery as follows.

1. Connect the charger power cord to the receptacle

Connecting the power cord will turn on the charger.

2. Insert the battery into the charger

Insert the battery firmly while observing its direction, until it contacts the bottom of the charger (the pilot lamp lights up). CAUTION If the pilot lamp does not light up, pull out the power cord from the receptacle and check the battery mounting condition. About 50 minutes is required to fully charge the battery at a temperature of about 20°C. The pilot lamp goes off to indicate that the battery is fully charged. The battery charging time becomes longer when a temperature is low or the voltage of the power source is too low. When the pilot lamp does not go off even if more than 120 minutes have elapsed after starting of the charging, stop the charging and contact your HiKOKI AUTHORIZED SERVICE CENTER. CAUTION If the battery is heated due to direct sunlight, etc., just after operation, the charger pilot lamp may not light up. At that time, cool the battery first, then start charging.

3. Disconnect the charger power cord from the

4. Hold the charger tight and pull out the battery

The cutting position can be regulated by moving the guide to the left or right after loosening its knob bolt. The guide may be mounted on either the right or left side of the tool.

(switch trigger and light switch) (1) For safe operation of the machine, a “switch lock” is provided on the side of a handle. If the “switch trigger” is pulled in a state where “switch lock” is pressed in the direction of the arrow mark, the main switch can be turned ON. And the “switch lock” is used as the “light switch”. If the “switch lock (light switch)” is pressed in a state, the light is turned ON. (2) After the switch is turned ON, even when you release your hand from the switch lock, the body continues running and the light continues being turned ON as long as you keep on pulling the switch trigger. (3) If you release the switch trigger, you can turn OFF the switch and the “switch lock” returns to the original position automatically and the light turns OFF too. CAUTION 䡬 Do not fix and secure the switch lock. Besides, keep your finger 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. 䡬 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. 䡬 If the main body is left as it is with the battery inserted, there can be a case where the [switch lock] touches the floor 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 in about 3 hours.

2. Cutting procedures

CAUTION 䡬 Recheck that the saw blade is securely clamped. 䡬 Confirm that the wing nut for adjusting the slot depth, the wing bolt for adjusting the angle of inclination are securely clamped. (1) Place the base on the material, then align the premarked line and the sawblade with the notch at the front of the base (Fig. 16). When the base is not slanted, use the large cutout as the guide (Fig. 16, Fig. 19(A)). If the base is slanted (45 degrees), use the small front scale as the guide (Fig. 16, Fig. 19(B)). (2) Ensure that the switch is turned to the ON position before the saw blade comes in contact with the lumber. The switch is turned ON when the trigger is squeezed; and OFF when the trigger is released. Moving the saw straight at a constant speed will produce optimum cutting. As the internal chemical substance of new batteries and batteries that have not been used for an extended period is not activated, the electric discharge might be low when using them the first and second time. This is a temporary phenomenon, and 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.

1. Setting up and checking the work environment

Check if the work environment is suitable by following the precautions.

2. Prepare a wooden workbench (Fig. 13)

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. CAUTION To avoid possible accident, always ensure that the portion of lumber remaining after cutting is securely anchored or held in position.

ADJUSTING THE SAW PRIOR TO USE

CAUTION Pull out battery before doing any adjusting.

1. Adjusting the cutting depth

As shown in Fig. 14, hold the handle with one hand while loosening the wing nut with the other. The cutting depth can be adjusted by moving the base to the desired position. In such manner adjust the cutting depth and then securely retighten the wing nut.

2. Adjusting the angle of inclination

As shown in Fig. 15 by loosening the wing bolt on the incline gauge, the saw blade may be inclined to a maximum angle of 50° in relation to the base. After having completed the adjustment, reconfirm that the wing bolt are firmly tightened. NOTE 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. 01Eng_C18DMR_DL_WE 11/21/08, 11:151415 English CAUTIONS 䡬 Before starting to saw, ensure that the saw blade has reached full speed revolution. 䡬 Should the saw blade be stopped or made an abnormal noise during operation, turn off the switch immediately. 䡬 When finished with a job, pull out the battery from the main body. 䡬 Twisting and forcibly pressing the saw during cutting can result in unreasonable pressure on the motor, so try to go straight quietly. 䡬 In the situation where the circular saw is continuously operated while replacing the battery with stocked spare batteries one after another, the motor tends to overheat. Therefore, whenever the housing becomes hot, give the saw a break for a while. 䡬 Avoid cutting operation in a state where the base bottom is afloat from the material being cut. Otherwise, the motor can get locked.

MOUNTING AND DISMOUNTING THE SAW

BLADE CAUTION To avoid serious accident, ensure the switch is in the OFF position, and pull out the battery.

1. Dismounting the saw blade

(1) Set the cutting volume at maximum, and place the Circular Saw as shown in Fig. 20. (2) Depress the lock lever, lock the spindle, and remove the left-hand bolt and washer (B) with the box wrench. (3) While holding the lower guard lever to keep the lower guard fully retracted into the saw cover, remove the saw blade (Fig. 21).

2. Mounting the Saw Blade

CAUTION If the left-hand bolt is worked using other tools than the provided box wrench, excessive tightening and insufficient tightening may take place resulting in injury. (1) Thoroughly remove any sawdust which has accumulated on the spindle, bolt and washers. (2) As shown in Fig. 22, the side of Washer (A) with a projected center the same diameter as the inner diameter of the saw blade and the concave side of Washer (B) must be fitted to the saw blade sides.

• Washer (A) is supplied for 2 types of saw blades with the hole diameters of 16 mm and 30 mm. (When buying the Circular Saw, one type of washer (A) is spplied.) In case the hole diameter of your saw blade does not correspond to that of washer (A), please contact the shop where you purchased the Circular Saw. (3) To assure proper rotation direction of the saw blade, the arrow direction on the saw blade must coincide with the arrow direction on the saw cover. (4) Using the fingers, tighten the left-hand bolt retaining the saw blade as much as possible. Then depress the lock lever, lock the spindle, and thoroughly tighten the left-hand bolt. CAUTION After having attached the saw blade, reconfirm that the lock lever is firmly secured in the prescribed position.

REPLACING LIGHT BULB

CAUTION 䡬 Make absolutely sure that the battery is removed from the main body before replacing the light bulb. 䡬 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. 䡬 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.

1. Detaching light bulb

(1) Remove the convex part of the light cover from the concave part of the handle cover, and then pull out the light cover in the arrow-marked direction as shown in Fig. 23. (2) Push the back of the socket, and remove the socket and the light bulb together from the handle cover (Fig. 24). (3) Remove the light bulb from the socket (Fig. 25).

2. Attaching light bulb

Take procedures here that are contrary to the detaching procedures. NOTE 䡬 When attaching the light bulb to the socket, insert the light bulb until it lightly bumps against the socket. 䡬 When attaching the socket to the handle cover, align the socket with the hole of housing while watching the back of the socket shown in Fig. 25, and insert the socket until it lightly bumps against the handle cover.

MAINTENANCE AND INSPECTION

CAUTION Pull out battery before doing any inspection or maintenance.

1. Inspecting the saw blade

Since use of a dull saw blade will degrade efficiency 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. Fail- ure to do so could result in serious hazard.

3. 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.

4. Performance checkup and maintenance of lower

guard Keep the lower guard in good shape for smooth performance at all times. Be sure to make prompt repair in case of any malfunction. For safe and proper working, always keep the machine and ventilation slots clean. The lower guard must always be able to more freely and retract 01Eng_C18DMR_DL_WE 7/1/13, 10:36 AM1516 English automatically. Therefore, always keep the area around the lower guard clean. Remove dust and chips by blowing out with compressed air or with a brush.

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. 26) 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 Make sure that the battery is fully charged when stored for a long period (3 months or more). The battery with smaller capacity may not be able to be charged when used, if stored for a long period. NOTE Storing lithium-ion batteries Make sure the lithium-ion batteries have been fully charged before storing them. Prolonged storage 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.

8. Service and repairs

All quality powe r tools will eventually require servicing or replacement of parts because of wear from normal use. To assure that only genuine replacement parts must be used, all service and repairs must be performed by a HiKOKI AUTHORIZED SERVICE CENTER, ONLY.
