Failure to follow the warnings and instructions 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. 1) Work area safety 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. 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. 15

16 English 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. 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 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 fi nger on the switch or energising power tools that have the switch on invites accidents. d) Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personal injury. e) Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations. f) Dress properly. Do not wear loose clothing or jewellery. Keep your hair, 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. 16

17 English 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 toolʼs operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools. f) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control. g) Use the power tool, accessories and tool bits etc. in accordance with these instructions, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from those intended could result in a hazardous situation. 5) 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. CAUTION Keep children and infirm persons away. When not in use, tools should be stored out of reach of children and infirm persons. IMPACT WRENCH SAFETY WARNINGS Hold power tool by insulated gripping surfaces, when performing an operation where the fastener may contact hidden wiring or its own cord. Fasteners contacting a live wire may make exposed metal parts of the power tool live and could give the operator an electric shock. ADDITIONAL SAFETY WARNINGS 1. When using the tool at a hight, make sure that there is nobody below. 2. Use earplugs if using for a long time use. 3. Switch the reversing switch only after the motor has stoped when it is necessary to change the direction of the rotation. 4. Use a step up transformer when a long extension cable is used. 5. Confirm the tightening torque by a torque wrench before use in order to assertain the correct tightening torque to be used. 17

18 English 6. Assemble the socket securely to the impact wrench with the socket pin and ring. 7. Confirm whether the socket has any cracks in it. 8. Always hold the handle and side handle of the impact wrench firmly. Otherwise the counterforce produced may result in inaccurate and even dangerous operation. SYMBOLS WARNING The following show symbols used for the machine. Be sure that you understand their meaning before use.

19 OPTIONAL ACCESSORIES (sold separately) 1. Variety of sockets Although the HiKOKI Impact Wrench is delivered with only one standard socket, ample sockets are available to cover impact tightening of various sizes and types of bolts. S D E L English B B (mm) Table 1 Ordinary Socket Long Socket Dimension (mm) Dimension (mm) S D E L Code No. S D E L Code No Extension bar : Code No The extension bar is convenient for working in very restricted spaces or when the socket provided cannot reach the bolt to be tightened. CAUTION When the extension bar is used the tightening torque is reduced slightly compared with the ordinary socket. So it is necessary to operate the tool a little longer to get the same torque. PRIOR TO OPERATION 1. Power source Ensure that the power source to be utilized conforms to the power requirements specifi ed on the product nameplate. 2. Power switch Ensure that the power switch is in the OFF position. If the plug is connected to a receptacle while the power switch is in the ON position, the power tool will start operating immediately, which could cause a serious accident. 19

20 English 3. Extension cord When the work area is removed from the power source, use an extension cord of sufficient thickness and rated capacity. The extension cord should be kept as short as practicable. 4. Check the receptacle If the receptacle only loosely accepts the plug, the receptacle must be repaired. Contact a licensed electrician to make appropriate repairs. If such a faulty receptacle is used, it may cause overheating, resulting in a serious hazard. 5. Confi rming condition of the environment Confi rm that the work site is placed under appropriate conditions conforming to prescribed precautions. 6. Mounting the side handle After loosening the handle, slide it over the main unit and tighten the handle to secure it. When sliding over the main unit, make sure to align the unit s protrusion with the side handle s slot. (Fig. 1) 7. Mounting the socket Select a socket matched to the bolt to be tightened or loosened. Insert the socket on the anvil of the wrench, and secure it with the pin and ring. When dismantling the socket, reverse the sequence. (Fig. 2) O-ring Pin Hex. socket Anvil Protrusion Handle HOW TO USE Fig. 1 Slot 1. Operation of switch (Fig. 3) The switch in this machine functions as a motor switch and rotational direction selector switch. When the switch is set to R indicated on the handle cover, the motor rotates clockwise to tighten the bolt. When the switch is set to L, the motor rotates counterclockwise to loosen the bolt. When the switch is released, the motor stops. CAUTION Be sure to turn the switch OFF and wait until Fig. 2 Switch Fig. 3 Hole the motor completely stops before changing the direction of wrench revolution. Switching while the motor is rotating will result in burning the motor. 20

21 English 2. Tightening and loosening bolts A hex socket matching the bolt or nut must fi rst 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 fi tted to the bolt, the bolt may turn with the nut, therefore preventing 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. Do not touch the bumper or hammer case during continuous operation The bumper and hammer case become hot during continuous screw tightening so be careful not to touch them at that time. 2. Work at a tightening torque suitable for the bolt under impact The optimum tightening torque for nuts and bolts differs with material and size of the nuts and bolts. An excessively large tightening torque for a small bolt may strech or break the bolt. The tightening torque increases proportionally to the operating time. Use the correct operating time for the bolt. 3. Selecting the socket to be matched to the bolt Be sure to use a socket which is matched to the bolt to be tightened. Using an improper socket will result not only 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 fi tting to the nut or anvil, consequently resulting in loss of tightening torque. Pay attention to wear of socket holes, and replace before further wear developes. Matching socket and bolt sizes are shown in Table 1 on page 19. The numerical value of a socket designation denotes the side to side distance (S) of its hex hole. 4. Holding the tool Hold the Impact Wrench fi rmly with both hands by the body handle and the side handle. 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. 5. Confi rm the tightening torque The following factors contribute to a reduction of the tightening torque. So confi rm 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) Line voltage: The tightening torque decreases when the line voltage becomes low. 21

22 English (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 (See Fig. 4). WR22SE WR25SE kgf m N m M22 70 (F10T) kgf m N m M24 70 (F10T) Rating 220V Rating 220V (sec.) (sec.) Tightening time Tightening time Fig. 4 (3) Diameter of bolt: The tightening torque differs with the diameter of the bolt. Generally a larger diameter bolt has a 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 metal through which the bolts are to be tightened. (5) Using optional parts: The tightening torque is reduced a little when an extension bar, universal joint or a long socket is used. (6) Clearance of the socket: A worn or deformed hex or a square-holed socket will not give an adequate tightness to the fi tting 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. Matching socket and bolt sizes are shown in Table 1 on page The protection function To protect the tool, the protection function will be activated, automatically shutting down the unit in the event of any problems. (Table 2 describes each situation for which the aforementioned may occur.) Tightening torque Tightening torque 22

23 23 English Table 2 Indicated Situation Automatic shutdown initiated by excessive load (*1) Automatic shutdown initiated due to the tool s internal temperature exceeding the specifi ed temperature level (*2) *1 Excessive load protection function For excessive load conditions, the tool will shutdown to prevent damage. Discontinue the heavy load task and unplug the power cord from the outlet. When the cord is plugged back in, the tool will recover. *2 Increased temperature protection function Automatic shutdown is activated to prevent damage from high temperatures. The tool s internal temperature will increase for tasks Hook Hanger involving the use of large currents of electricity, or when used in high temperature environments. Please allow the tool to rest for 10 to 15 minutes before continuing a task. 7. Using the hook hanger (WR25SE) When using the hook hanger, make sure the rope or wire is securely fastened to the hanger. (Fig. 5) Fig. 5 CAUTION Always make sure to use a rope or wire with sufficient strength to support the weight of the main unit and withstand impact from dropping. MAINTENANCE AND INSPECTION WARNING Be sure to switch power OFF and disconnect the plug from the receptacle during maintenance and inspection. 1. Inspecting the socket A worn or deformed hex or a square-holed socket will not give an adequate tightness to the fi tting between the nut or anvil, consequently resulting in loss of tightening torque. Pay attention to wear of socket holes periodically, and replace with a new one if needed. 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.

24 English 4. Replacing supply cord If the replacement of the supply cord is necessary, this has to be done by the manufacturer of this agent in order to avoid a safety hazard. 5. Service parts list CAUTION Repair, modification 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. In the operation and maintenance of power tools, the safety regulations and standards prescribed in each country must be observed. 24
