  • Page 2 To the user In order to use the torque wrench properly and safely, please read this instructions before operation. If any question, please contact a Tohnichi authorized distributor or Tohnichi office. Keep this operating instruction for future use. ! Warning Use only a dedicated charger and storage battery.
  • Page 3 ! Cautions (1) Keep the working place clean and tidy. Working in a messy condition may cause accidents. (2) Keep children away from the product or the work place. As a basic rule, do not let any other person than the user himself should touch the product.
  • Page 4 Doing otherwise may cause injuries. Conduct periodic check on the cord of the charger, and request repair or replacement to the authorized distributor or Tohnichi if damaged. If you keep using the damaged cord, it may cause electric shock, or fire.
  • Page 5 (10) Hold the handle on the effective length line and apply force at right angle to the torque wrench. If you should find any irregular performance of the product, stop using the product immediately and keep it in a safe place. Contact Tohnichi immediately.
  • Page 6 Explanation of words Please refer to the below explanation of words which are used in this operation manuals. - Tightening mode: Tightening mode includes single-spindle tightening mode and production tightening mode. Tightening modes should be selected according to the user conditions. Single-spindle tightening mode is selected at default setting (delivery setting).
  • Page 7 - Tightening torque (setting): This is the tightening torque value to set at the torque tightening stage in the production tightening mode. After passing this torque, the operator will be informed by the blue LED and the buzzer. When it goes over the upper limit, the red LED lights up and another buzzer goes off to alarm the operator.
