meter. If necessary, readjust the torque up or down, following the
above instructions.
This tool can achieve a maximum torque of approximately. 4.5 N-m
and a minimum torque of approximately 1.5 N-m.
Setting the Indicator Ring
Once the desired torque is confirmed with a torque meter, use the
wireform tool to set the indicator ring. Place the wireform tool about
1/4" into the holes on the front ring and turn the front ring until the
numbers on the ring match the torque setting indicated by the torque
meter (Figure 5).Setting the indicator ring will also seal the
adjustment holes and prevent dirt from getting into the tool.
NOTE: Adjusting the indicator ring does not change the torque
setting of the tool.
