The battery will discharge rapidly and damage to the unit may occur. 6)During charging, the charger may become slightly warm. This is normal. Do NOT charge the battery for a long period. 7)When storing or carrying the tool, set the Forward/Reverse lever to the center position (switch lock). 8)Do not strain the tool by holding the trigger switch halfway (speed control mode) so that the motor stops. II.ASSEMBLY NOTE: When attaching or removing a bit or socket, disconnect battery pack from tool or place the trigger switch in the center position (switch lock). Attaching or Removing Bit (EY7270) 1. Hold the collar of the quick connect chuck and push it outwards. . Insert the bit into the chuck. 3. The collar will return to its original position when it is released. 4. Pull the bit to make sure it does not come out. 5. To remove the bit, pull back on the collar in the same way. CAUTION: If the collar does not return to its original position or the bit comes out when pulled on, the bit has not been properly attached. Make sure the bit is properly attached before use. Attaching or RemovingSocket (EY7271) 1. Attaching Socket Attach the socket by sliding the female detent on the bottom of the socket to the square drive on the body. Make sure the socket is firmly connected to the body. . Removing Socket Pull out the socket. NOTE: Attaching or Options and Sockets original Removing Original Keep the body above freezing point (0°C 3 °F) when attach or detach to options and sockets the square drive on the body. The cushion rubber in the square drive to push up the ball may get hard under freezing point. This requires extra force in detaching and attaching sockets. -5 EY7270(EU).indb 5 13:24:54 2006/05/25 If the hex quick connect chuck attachment (optional) is attached, the EY7 71 impact wrench can be used in the same manner as driver model EY7 70. Symbol Meaning V Volts Direct current n0 No load speed …/min Revolutions or reciprocation per minutes Attaching or Removing Battery Pack 1. To connect the battery pack: Insert the battery pack. It snaps into place to indicate proper connection. . To remove the battery pack: Press the two battery pack release buttons on the sides of the battery pack. Slide the battery pack out of the tool body. III.OPERATION Select the Impact Mode The tool has an impact mode selection feature. By pressing the impact mode button, the impact strength can be selected according to Hard, Medium or Soft. Pressing the button toggles the mode from Hard > Medium > Soft. (The factory default setting is the Hard impact mode.) In the Soft impact mode the torque is lower to prevent damaging material caused by overtightening. This mode is recommended when you wish to minimize possible damage to small screw heads or to a soft material surface to be fastened by controlling the variable speed control trigger. The Medium impact mode also has a lower torque setting to help prevent damage to materials caused by overtightening. This mode is recommended when you wish to minimize possible damage to screws and screw heads. - The Hard impact mode is for selecting maximum torque and rotational speed. CAUTION: Do not press the impact mode button before rotation has stopped completely.

Recommended Application For hard impact power mode. Fastening long wood screws. Tightening bolts when installing devices, etc. For medium impact power mode. Fastening small diameter screws into hard materials. Driving machine screws wheninstalling devices. For soft impact power mode. Installing gypsum board. Installing soft metal window flame. Installing interior finishings. Switch and Forward/Reverse Lever Operation ReverseForward Switch lock 6 EY7270(EU).indb 6 13:24:57 2006/05/25 CAUTION: To prevent damage, do not operate Forward/Reverse lever until the bit comes to a complete stop. Forward Rotation Switch Operation 1. Push the lever for forward rotation. . Depress the trigger switch slightly to start the tool slowly. 3. The speed increases with the amount of depression of the trigger for efficient tightening of screws. The brake operates and the bit stops immediately when the trigger is released. 4. After use, set the lever to its center position (switch lock). Reverse Rotation Switch Operation 1. Push the lever for reverse rotation. Check the direction of rotation before use. . Depress the trigger switch slightly to start the tool slowly. 3. After use, set the lever to its center position (switch lock). CAUTION: To eliminate excessive temperature increase of the tool surface, do not operate the tool continuously (using two or more battery packs consecutively). Tool needs cool-off time before switching to another pack. LED Light CAUTION: The built-in LED light is designed to illuminate a small work area temporarily. Do not use it as a substitute for a regular flas...
