seconds) The automatic stopfunction has been activated. Red (For approx. 5minutes) CAUTION: • When the tool stops automatically after the switch is released during impact- mode tightening and then re-engaged within 1 second, the red lamp will light up to indicate the risk of excessive torque application as a result of re-tightening. NOTE • The tightening confirmation lamp will not turn on under the following conditions: • When the torque clutch is set to “F” • During reverse rotation operation • The lamp turns off when the tool is in operation. Control Panel (1) ( ) (3) (1) LED light Pressing the button toggles the LED light on and off. The light illuminates with very low current, and it does not adversely affect the performance of the tool during use or its battery capacity. CAUTION: • The built-in LED light is designed to illuminate the small work area temporarily. • Do not use it as a substitute for a regular flashlight, since it does not have enough brightness. This tool has the built-in LED light. Caution: DO NOT STARE INTO BEAM. Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure. -8 (2) The battery indication lamp • Use the battery indication lamp to check how much power is left in the battery. • Battery life varies slightly with ambient temperature and battery characteristics. The lamp is designed to provide a rough indication of remaining battery life. Battery indication lamp Indicator Battery status Fully charged Approx. 40% or lessremaining Flashing FlashingApprox. 0% or less remaining (indicates needto recharge battery) The battery pack will needto be charged soon. Flashing No chargeThe battery pack needs tobe charged. (The tool’s automatic power-off function will activate at this stage.) Automatic poweroff function • The automatic power-off function is designed to prevent a loss of tightening torque due to reduced battery voltage. Once it has been activated, the tool will not operate until the battery pack has been charged (or replaced with a fresh unit), even if the trigger is depressed. Battery indication lamp Indicator Flashing NOTE: • All 3 bars on the battery indication lamp will flash when the automatic power-off function is activated. • When the battery indication lamp begins flashing, the battery pack should be charged (or replaced with a fresh unit) immediately. • Be sure to fully charge the battery pack in question after activation of the automatic power-off function. Failure to do so may prevent the automatic power-off function from being properly deactivated. (3) The torque control function • The torque control function calculates the load from the motor’s rotational angle during the hammer impact and determines that the bolt has been properly seated when a preset load value is exceeded. Driving is then automatically stopped after a preset number of impacts have been delivered to the bolt. CAUTION: • Always check the tool’s tightening torque before use. Improper tool operation may result in excessive or inadequate tightening. CAUTION: • Always operate the tool with the switch fully engaged. The torque control function will not operate when the switch is not sufficiently engaged, preventing the tool from stopping automatically. • In work where a heavy load comes to bear during tightening, the load may be interpreted as the seating of the bolt, preventing the bolt from being completely tightened. • Repeated tightening of the same bolt may break the bolt or deform the material into which the bolt is being driven as a result of excessive tightening. • The tightening torque value and precision vary with factors such as the material into which the bolt is being driven and the condition of the socket being used. Adjust the torque as necessary for the work being performed. Bolt tightening torque varies due to the factors described below. 1) Bolt • Bolt diameter: Tightening torque generally increases with bolt diameter. • Torque coefficient (indicated by the bolt manufacturer), grade, length, etc. -9 ) Other • Bit and socket condition: Material, amount of play, etc. • Use of a universal joint or socket adapter • User: Manner in which the tool is applied to the bolt, strength with which the tool is held, manner in which the tool’s switch is engaged • Condition of object being tightened: Material, seating surface finish Setting the tool to configuration mode 1. Turn off the control panel. • If the control panel is on, remove and then reinsert the battery pack. . Engage the switch while pushing the button and then release both the button and the switch. • After all the LED lamps have turned off, the control panel will flash and change to configuration mode. NOTE: • Tools ship from the factory set to “F” mode (torque control function off). • The control panel will turn off if the tool is not operated for a period of 5 minutes.
