Torque adjustment The Yokota YZ-T series are battery hydraulic shut-off impulse wrenches with electronic controlled shut-off. The electronics measure the load on the motor of each impulse. The load on the motor is called “value”. The higher the value, the higher the torque in the joint. The number of impulses are counted also. - Page 4 Measured value Maximum value Cut value Start value Minimum number of impulses Maximum number of impulses Number of impulses Value too high Number of impulses too low Value too low Number of impulses too high Cycle OK The torque (reached in the joint) is depending on 3 settings: The motor speed: Output value Cut value...

Page 10: Maintenance
Changing the speed and or the cut value will have an influence on the number of impulses. F or Yokota impulse wrenches we advise to do a preventive oil change maintenance after 250.000 cycles. 1 cycle is 0.5 seconds impulsing (hard joint). Oil change is including replacing the service kit. - Page 11 Trouble Probable cause Action The tool does not operate. The motor is over-heated. Wait until the motor cools down and the LED switches The battery pack is over-discharged. The battery voltage falls below a certain level and protective function is activated. Charge the battery pack.
