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.

5) Battery tool use and care

a) Recharge only with the charger specified by the manufacturer. (Original instructions) 01Eng_WH14DBAL2_WE 7/10/12, 16:146English

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.

5. Check that the socket is not cracked or broken.

Broken or cracked sockets are dangerous. Check the socket before using it.

6. Secure the socket with the socket pin and the ring.

If the socket pin or ring securing the socket is damaged, the socket may come off from the impact wrench, which is quite dangerous. Do not use socket pins or rings that are deformed, worn out, cracked, or in any other way damaged. Always make sure to install the socket pin and ring in the correct position.

7. Check the tightening torque.

The appropriate torque for tightening a bolt depends on the material the bolt is made of, its dimensions, grade, etc. Also, the tightening torque generated by this impact wrench depends on the materials and dimensions of the bolt, how long the impact wrench is applied for the way in which the socket is installed, etc. Also the torque when the battery has just been charged and when it is about to run out are slightly different. Use a torque wrench to check that the bolt has been tightened with the appropriate torque.

8. Stop the impact wrench before switching the

direction of rotation. Always release the switch and wait for impact wrench to stop before switching the direction of rotation.

9. Never touch the turning part.

Do not allow the turning socket section to get near your hands or any other part of your body. You could be cut or caught in the socket.

(2) Regarding the temperatures of the rechargeable battery The temperatures for rechargeable batteries are as shown in Table 2, and batteries that have become hot should be cooled for a while before being recharged. Table 2 Recharging ranges of batteries (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) NOTE: The charging time may vary according to temperature and power source voltage.

4. Disconnect the charger’s power cord from the

5. Hold the charger firmly and pull out the battery.

NOTE: After operation, pull out batteries from the charger first, and then keep the batteries properly. 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 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. CAUTION: 䡬 When the battery charger has been continuosly used, the battery charger will be heated, thus constituting the cause of the failures. Once the charging has been completed, give 15 minutes rest until the next charging. 䡬 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. 䡬 When the pilot lamp flickers 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 your authorized Service Center.

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 firmly. If it is at all loose it could come off and cause an accident.

3. Installing the bit (WH14DBAL2 / WH18DBAL2)

Always follow the following procedure to install driver bit. (Fig. 5) (1) Pull the guide sleeve away from front of the tool. (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.

4. Selecting the socket matched to the bolt

(WR14DBAL2 / WR18DBAL2) Be sure to use a socket which is matched to the bolt to be tightened. Using an improper socket will not only result in insufficient tightening but also in damage to the socket or nut. A worn or deformed hex. or square-holed socket will not give an adequate tightness for fitting to the nut or anvil, consequently resulting in loss of tightening torque. Pay attention to wear of socket hole, and replace before further wear has developed.

5. Installing a socket (WR14DBAL2 / WR18DBAL2)

Select the socket to be used. 䢇 Pin, O-ring type (1) Align the hole in the socket with the hole in the anvil and insert the anvil into the socket. (2) Insert the pin into the socket. (3) Attach the ring to the groove on the socket. 䢇 Plunger type (Fig.6) Align the plunger located in the square part of the anvil with the hole in the hex. socket. Then push the plunger, and mount the hex. socket on the anvil. Check that the plunger is fully engaged in the hole. When removing the socket, reverse the sequence. 䢇 Retaining ring type (1) Align the square portions of the socket and the anvil with each other. (2) Make sure to firmly install the socket by pushing it all the way into the anvil. (3) When removing the socket, pull it out of the anvil. CAUTION: 䡬 Please use the designated attachments which are listed in the operations manual and HiKOKI’s catalog. Accidents or injuries could result from not doing so.

䡬 Make sure to firmly install the socket in the anvil. If the socket is not firmly installed it might come out and cause injuries.

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. 7) (The

marks are provided on the body.)

䡬 When the trigger switch is depressed, the tool rotates. When the trigger is released, the tool stops. 䡬 The rotational speed of the drill 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. NOTE: A buzzing noise is produced when the motor is about to rotate. This is only a noise, not a machine failure.

The hook is used to hang up the power tool to your waist belt while working. CAUTION: 䡬 When using the hook, hang up the power tool firmly not to drop accidentally. If the power tool is dropped, it may lead to an accident. 䡬 When carrying the power tool with hooked to your waist belt, do not fit any bit to the tip of power tool. If the sharp bit such as drill is fitted to the power tool when carrying it with hooked to your waist belt, you will be injured. 䡬 Install securely the hook. Unless the hook is securely installed, it may cause an injury while using. (1) Removing the hook. Remove the screws fixing the hook with Philips screw driver. (Fig. 8) (2) Replacing the hook and tightening the screws. Install securely the hook in the groove of power tool and tighten the screws to fix the hook firmly. (Fig. 9)

4. 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.10) When releasing your finger 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. As the remaining battery indicator shows somewhat differently depending on ambient temperature and battery characteristics, read it as a reference. NOTE: 䡬 Do not give a strong shock to the switch panel or break it.It may lead to a trouble. 䡬 To save the battery power consumption, the remaining battery indicator lamp lights while pressing the remaining battery indicator switch.

5. 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. 11) To prevent the battery power consumption, turn off the LED light frequently. CAUTION: Do not expose directly your eye to the light by looking into the light. If your eye is continuously exposed to the light, your eye 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.

6. Tightening mode selector function (Fig. 12)

CAUTION: 䡬 Do not subject the switch panel to shock or damage. 䡬 Select high/low mode while the trigger switch is released. Failure to do so could result in malfunction. (1) High/Low selector switch The rotation speed changes in 4 steps (900, 1500, 2200, 2800/2900 min

) each time the high/low selector switch is pressed. NOTE: 䡬 The appropriate mode differs depending on the screw and the material being screwed. Drive in a few test screws and adjust the mode setting accordingly. 䡬 The high/low selector switch can only be set after the battery has been installed in the driver and the trigger switch has been pulled once. 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. 01Eng_WH14DBAL2_WE 7/10/12, 16:1412English

7. Tightening and loosening screws (WH14DBAL2 /

WH18DBAL2) 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 impact driver just enough to keep the bit fitting the head of the screw. CAUTION Applying the impact driver for too long tightens the screw too much and can break it. Tightening a screw with the impact driver 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 impact driver lined up straight with the screw.

8. Tightening and loosening bolts

A hex. socket matching the bolt or nut must first be selected. Then mount the socket on the anvil, and grip the nut to be tightened with the hex. socket. Holding the wrench in line with the bolt, press the power switch to impact the nut for several seconds. If the nut is only loosely fitted to the bolt, the bolt may turn with the nut, therefore mistaking proper tightening. In this case, stop impact on the nut and hold the bolt head with a wrench before restarting impact, or manually tighten the bolt and nut to prevent them slipping. OPERATIONAL CAUTIONS

1. Resting the unit after continuous work

After use for continuous bolt-tightening work, rest the unit for 15 minutes or so when replacing the battery. The temperature of the motor, switch, etc., will rise if the work is started again immediately after battery replacement, eventually resulting in burnout. NOTE: Do not touch the metal parts, as it gets very hot during continuous work.

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. Use a tightening time suitable for the screw

The appropriate torque for a screw differs according to the material and size of the screw, and the material being screwed etc., so please use a tightening time suitable for the screw. In particular, if a long tightening time is used in the case of screws smaller than M8, there is a danger of the screw breaking, so please confirm the tightening time and the tightening torque beforehand.

4. Work at a tightening torque suitable for the bolt

under impact The optimum tightening torque for nuts or bolts differs with material and size of the nuts or bolts. An excessively large tightening torque for a small bolt may stretch or break the bolt. The tightening torque increases in proportion to the operaton time. Use the correct operating time for the bolt.

Hold the impact wrench firmly with both hands. In this case hold the wrench in line with the bolt. It is not necessary to push the wrench very hard. Hold the wrench with a force just sufficient to counteract the impact force.

6. Confirm the tightening torque

The following factors contribute to a reduction of the tightening torque. So confirm the actual tightening torque needed by screwing up some bolts before the job with a hand torque wrench. Factors affecting the tightening torque are as follows. (1) Voltage When the discharge margin is reached, voltage decreases and tightening torque is lowered. (2) Operating time The tightening torque increases when the operating time increases. But the tightening torque does not increase above a certain value even if the tool is driven for a long time. (3) Diameter of bolt The tightening torque differs with the diameter of the bolt. Generally a larger diameter bolt requires larger tightening torque. (4) Tightening conditions The tightening torque differs according to the torque ratio; class, and length of bolts even when bolts with the same size threads are used. The tightening torque also differs according to the condition of the surface of workpiece through which the bolts are to be tightened. When the bolt and nut turn together, torque is greatly reduced. (5) Using optional parts (WR14DBAL2 / WR18DBAL2) The tightening torque is reduced a little when an extension bar, universal joint or a long socket is used. (6) Clearance of the socket (WR14DBAL2 / WR18DBAL2) A worn or deformed hex. or a square-holed socket will not give an adequate tightness to the fitting between the nut or anvil, consequently resulting in loss of tightening torque. Using an improper socket which does not match to the bolt will result in an insufficient tightening torque. (7) Tightening torque varies, depending on the battery’s charge level. Examples of tightening mode selector function settings Low 1 Low 2 Medium High Rotation speed 2800 min

Use “Delicate work” Tightening small diameter screws (M6 or similar), etc. “Light load work” Affixing plasterboard (select according to the hardness of the base material) etc. “Heavy load work” Tightening long screws, coach screws, bolts, etc. 01Eng_WH14DBAL2_WE 7/10/12, 16:1413English

Using a broken bit or one with a worn out tip is dangerous because the bit can slip. Replace it.

2. Inspecting the socket (WR14DBAL2 / WR18DBAL2)

A worn or deformed hex. or a square-holed socket will not give an adequate tightness to the fitting between the nut or anvil, consequently resulting in loss of tightening torque. Pay attention to wear of a socket holes periodically, and replace with a new one if needed.

3. 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 may result in serious hazard.

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.

5. Cleaning of the outside

When the impact driver is stained, wipe with a soft dry cloth or a cloth moistened with soapy water. Do not use chloric solvents, gasoline or paint thinner, as they melt plastics.

Store the impact driver 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 be charged when used, if stored for a long period.
