14 GENERAL SAFETY RULES WARNING! Read all instructions Failure to follow all instructions listed below may result in electric shock, fi re and/or serious injury. The term power tool in all of the warnings listed below refers to your mains operated (corded) power tool or battery operated (cordless) power tool. SAVE THESE INSTRUCTIONS 1) Work area a) Keep work area clean and well lit. Cluttered and 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 of 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. 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 influence of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious personal injury. b) Use safety equipment. Always wear eye protection. Safety equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries. c) Avoid accidental starting. Ensure the switch is in the off position before plugging in. Carrying power tools with your fi nger on the switch or plugging in power tools that have the switch on invites accidents. 14 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 these devices 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 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 and in the manner intended for the particular type of power tool, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from intended could result in a hazardous situation. 5) Battery tool use and care a) Ensure the switch is in the off position before inserting battery pack. Inserting the battery pack into power tools that have the switch on invites accidents. b) 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 fi re when used with another battery pack. c) Use power tools only with specifically designated battery packs. Use of any other battery packs may create a risk of injury and fi re.

15 d) 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. e) 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. 6) Service 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. PRECAUTIONS FOR ELECTRONIC PULSE DRIVER 1. This is portable tool for drilling, tightening and loosenig screws. Use it only for these operation. 2. Use the earplugs if using for a long time. 3. One-hand operation is extremely dangerous; hold the unit fi rmly with both hands when operating. 4. After installing the driver bit, pull lightly out the bit to make sure that it does not come loose. If the bit is not installed properly, it can come loose during use, which can be dangerous. 5. Use the bit that matches the screw. 6. Tightening a screw with the tool at an angle to that tool can damage the head of the screw and the proper force will not be transmitted to the screw. Tighten with this tool lined up straight with the screw. 7. Always charge the battery at a temperature of 0 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 greater than 40 C. The most suitable temperature for charging is that of C. 8. Do not use the charger continuously.

(2) Regarding the temperatures of the rechargeable battery The temperatures for rechargeable batteries are as shown in the Table 2, and batteries that have become hot should be cooled for a while before being recharged. Table 2 Recharging ranges of batteries Rechargeable batteries Temperatures at which the battery can be recharged BSL1430, BSL C 50 C (3) Regarding recharging time Depending on the combination of the charger and batteries, the charging time will become as shown in Table 3. Table 3 Charging time (At 20 C) Charger UC18YRSL Battery BSL1430, BSL1830 Approx. 45 min. NOTE: The charging time may vary according to temperature and power source voltage. 4. Disconnect the charger s power cord from the receptacle. 5. Hold the charger firmly and pull out the battery. NOTE: After operation, pull out batteries from the charger fi rst, and then keep the batteries properly. 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. 18 CAUTION When the battery charger has been continuously used, the battery charger is heated, thus constituting the cause of the failures. Once the charging has been completed, give 15 minutes rest until the next charging. If the battery is recharged when it is warm due to battery use or exposure to sunlight, the pilot lamp map light in green. The battery will not be recharged. In such a case, let the battery cool before charging. When the pilot lamp fl ickers in red (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 HiKOKI authorized Service Center. PRIOR TO OPERATION 1. Preparing and checking the work environment Make sure that the work site meets all the conditions laid forth in the precautions. 2. Checking the battery Make sure that the battery is installed fi rmly. If it is at all loose it could come off and cause an accident. 3. Installing the bit Driver bit Always follow the following procedure to install driver bit. (Fig. 5) (1) Pull the guide sleeve back. (2) Insert the bit into the hexagonal hole in the anvil. (3) Release the guide sleeve and it returns to its original position. CAUTION If the guide sleeve does not return to its original position, then the bit is not installed properly. Drill bit A drill with hexagonal shank can be attached directly to the tool. To attach a drill without hexagonal shank, you need to have the drill chuck adapter set sold separately. (1) Insert the drill bit into the chuck. (2) Use the chuck key to secure the drill bit, tightening the chuck by each of the three holes in turn. (Fig. 11) Use an iron drill to make a pilot hole for a wood screw or a 10 mm or smaller hole. (1) Insert the drill bit into the chuck. (2) Use the chuck key to secure the drill bit, tightening the chuck by each of the three holes in turn. (Fig. 11)

19 HOW TO USE 1. Mode selection function WARNING Use this tool with the mode selection dial set to the correct position (it should be clicked and locked in place). Ignoring this may cause an unexpected behavior of the tool and result in breaking materials/screws or injury. CAUTION Do not apply strong impact to the mode selection dial. The operation mode can be changed by turning the mode selection dial on the tool and aligning it with the triangular mark. The operation mode can be selected from fi ve different modes described in the below table. NOTE: The tightening torque obtained by each mode varies according to the screw and material being screwed. Adjust the mode selection dial after test-tightening a few screws. Use the bolt mode to tighten bolts. Turning the mode selection dial with the tool switched on does not change the mode. Switch off the tool before changing the operation mode. Example of mode selection Operation mode Marking Maximum torque Application Notes 3 Diagonal tightening of 75 mm screw Electronic pulse Wood screw 2 mode tightening Tightening of mm screw 1 Tightening screw shorter than 50 mm 30 N m Bolt mode 33 N m *1 Bolt tightening Self drilling 2 Self drilling screw tightening (ø 5 or ø 6) screw mode 1 Self drilling screw tightening (ø 3.5 or ø 4) *2 Drill mode 11 N m Drilling N m *3 Electronic clutch mode * N m Machine screw (M6) or tapping screw tightening, Gypsum board fi xing Use the bit and socket which are suitable for the screw diameter. When using the drill mode, be sure not to stop the motor rotation. *1: WM14DBL: 30 N m, WM18DBL: 33 N m. *2: Before fi xing a thin plate with a self drilling screw, make sure that the thickness of the plate is suitable for the screw diameter. *3: With the electronic clutch mode 4 or 5 the tool may execute reverse rotation briefl y when the load increases in order to reduce a risk of screw-head damage. *4: The tool starts up in low rotation speed and tightens softly. The motor automatically stops rotating when the torque reaches to the number set on the dial in order to reduce over tightening. The clutch sound such as of the mechanical type will not be generated. 2. Characteristics of Electronic Pulse Driver Unlike a conventional impact driver, the electronic pulse driver generates the striking force by rotating the motor in regular and reverse directions repeatedly. This mechanism has helped to provide quieter operation. The following characteristics are uncommon to a conventional impact driver, however these are not signs of malfunction. The tool tends to be heated by continuous screw tightening. To protect the motor and electronic parts that control the motor operation, this tool is equipped with a temperature protection circuit. Depending on the screw and material being screwed, the striking operation may start early. Since the striking operation causes temperature increase of the motor and electronic parts, the temperature protection circuit may be activated early. Refer to "1. Continuous operation" on page 21 for recovering from the operation stop caused by the temperature protection circuit. Also, the electronic pulse driver controls the motor rotation consistently to provide the optimum operation for each mode. Because of this, the following cases can occur during operation. The behavior at operation start differs by the mode. The self drilling screw mode (1) gradually increases the speed. The electronic clutch mode (regular rotation) rotates the motor at a very slow speed for a certain period after the start and then increases the speed. On the other hand, the electronic clutch mode (reverse rotation) meets the preset rotation speed immediately after the start. 19

20 Rotation speed Electronic pulse mode, self drilling screw mode (2) and drill mode Self drilling screw mode (1) Bolt mode Electronic clutch mode (reverse rotation) Electronic clutch mode (regular rotation) Elapsed time after switching on The tool may not return to the initial status from the striking operation. When the bit or socket is removed from the screw or bolt while the switch is being pulled, the tool may continue the striking operation. To return to the initial status, turn off the switch and then start the next operation. Motor rotation speed does not decrease even when the remaining battery power becomes low. Since this tool adopts the constant-speed control, the rotation speed is almost unchanged even when the remaining amount of the battery becomes low. This allows users to operate the tool efficiently until the battery runs down. However, it is difficult to know the remaining battery power from the rotation speed and the tool may stop suddenly during work. Check the remaining battery power by pressing the remaining battery indicator switch at times. The tool stops automatically when the electronic clutch is actuated. Quiet screw tightening can be performed without clutch sound generated by the mechanical type. The tool stops automatically when the clutch is actuated. If you continue to use the tool, turn off the switch once and turn it on again. When the tool does not operate even without load, the remaining amount of the battery is low. In this case, recharge the battery immediately. 3. Check the rotational direction The bit rotates clockwise (viewed from the rear side) by pushing the R-side of the push button. The L-side of the push button is pushed to turn the bit counterclockwise. (See Fig. 6) (The and marks are provided on the body.) CAUTION The push button can not be switched while the tool is turning. To switch the push button, stop the tool, then set the push button. 4. Switch operation When the trigger switch is depressed, the tool rotates. When the trigger is released, the tool stops. The rotational speed can be controlled by varying the amount that the trigger switch is pulled. Speed is low when the trigger switch is pulled slightly and increases as the trigger switch is pulled more. 5. Using the hook The hook is used to hang up the power tool to your waist belt while working. CAUTION When using the hook, hang up the power tool fi rmly not to drop accidentally. If the power tool is dropped, it may lead to an accident. When carrying the power tool hooked to your waist belt, do not fi t any bit to the tip of power tool. If the sharp bit such as drill is fi tted to the power tool when carrying it hooked to your waist belt, you will be injured. Install securely the hook. Unless the hook is securely installed, it may cause an injury while being used. (1) Removing the hook. Remove the screws fi xing the hook with Philips screw driver.(fig. 7) (2) Replacing the hook and tightening the screws. Install securely the hook in the groove of power tool and tighten the screws to fi x the hook fi rmly. (Fig. 8) 6. About Remaining Battery Indicator When pressing the remaining battery indicator switch, the remaining battery indicator lamp lights and the battery remaining power can be checked. (Fig. 9) When releasing your fi nger from the remaining battery indicator switch, the remaining battery indicator lamp goes off. The Table 4 shows the state of remaining battery indicator lamp and the battery remaining power. Table 4 State of lamp Battery Remaining Power The battery remaining power is enough. The battery remaining power is a half. The battery remaining power is nearly empty. Re-charge the battery soonest possible. As the remaining battery indicator shows somewhat differently depending on ambient temperature and battery characteristics, read it as a reference. NOTE: Do not give a strong shock to the switch panel or break it. It may lead to a trouble. To save the battery power consumption, the remaining battery indicator lamp lights while pressing the remaining battery indicator switch. 7. How to use the LED light Every time you press the light switch on the switch panel, the LED light lights or goes off. (Fig. 10) To prevent the battery power consumption, turn off the LED light frequently. CAUTION Do not expose directly your eyes to the light by looking into the light. If your eyes are continuously exposed to the light, your eyes will be hurt. NOTE: To prevent the battery power consumption caused by forgetting to turn off the LED light, the light goes off automatically in about 15 minutes. 8. Tightening and loosening screws Install the bit that matches the screw, line up the bit in the grooves of the head of the screw, then tighten it. Push the tool just enough to keep the bit fi tting the head of the screw. 20

21 CAUTION Applying the tool for too long tightens the screw too much and can break it. Tightening a screw with the tool at an angle to that screw can damage the head of the screw and the proper force will not be transmitted to the screw. Tighten with this tool lined up straight with the screw. Use the bit that fi ts the cross recess on the screw head. Make sure to use an appropriate bit especially when tightening self drilling screws since using an inappropriate bit can topple the screws. 9. Work amount possible with one charging The following table shows the approximate amount of work to be carried out by the tool with one charging. (The number of screws tightened and that of boring operations differ slightly according to the hardness of wood or metal, the ambient temperature, the charger properties, etc.) Operation mode Operation Model WM14DBL WM18DBL Electronic pulse mode Wood screw tightening ø Lauan Approx. 240 Approx. 290 Bolt mode Bolt tightening M10 30 S10C Approx. 750 Approx. 900 Self drilling screw mode Self drilling screw tightening ø 5 19 C-channel t2.3 + SPCC t1.6 Approx. 160 Approx. 190 Woodwork drilling ø 15 American pine t18 Approx. 450 Approx. 540 Drill mode Steel drilling ø 6.5 SPCC t1.6 Approx. 120 Approx. 145 Mortar drilling ø 6 30 Mortar Approx. 80 Approx. 95 Electronic clutch mode Machine screw tightening M6 12 S10C Approx Approx OPERATIONAL CAUTIONS 1. Continuous operation When you perform the striking operation continuously, the temperature protection circuit may be activated early. (Refer to "2. Characteristics of Electronic Pulse Driver" on page 19.) When the activated temperature protection circuit stops the tool, the LED light fl ashes to indicate that the tool is heated to high temperature. The LED light goes off automatically after approx. 30 seconds. When you perform continuous operation, allow the tool to rest for around 15 minutes at a replacement of rechargeable battery. NOTE: When the tool is stopped by the activated temperature protection circuit, allow the tool to cool sufficiently. You can use the tool again when it cools down. While the tool is not cooled sufficiently, it cannot start up by turning the switch to on. The LED light fl ashes while the switch is turned on. Please wait until the tool cools down sufficiently. Do not touch the nose part of the tool during continuous operation. It is heated to high temperature. 2. Cautions on use of the speed control switch This switch has a built-in, electronic circuit which steplessly varies the rotation speed. Consequently, when the switch trigger is pulled only slightly (low speed rotation) and the motor is stopped while continuously driving in screws, the components of the electronic circuit parts may overheat and be damaged. 3. Holding the tool and applying the pressing force Make sure to hold the tool securely with your both hands, and keep the tool straight to a screw or bolt. There is no need to press the tool excessively against materials. Be careful not to apply excessive pressing/prying force to the tool. It may damage the tool. MAINTENANCE AND INSPECTION 1. Inspecting the tool Since use of a dull tool will degrade efficiency and cause possible motor malfunction, sharpen or replace the tool 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 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. Cleaning of the outside When the 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. 5. Storage Store the tool in a place in which the temperature is less than 40 C and out of 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 becharged when used, if stored for a long period. 6. Service parts list CAUTION Repair, modifi cation and inspection of HiKOKI Power Tools must be carried out by a HiKOKI Authorized Service Center. This Parts List will be helpful if presented with the tool to the HiKOKI Authorized Service Center when requesting repair or other maintenance.
