Method of adjustment of output
8.4.1.
Adjusting the output by rotation speed of the motor
Output value is adjusted by changing the high speed setting of the motor.
If the high speed setting of the motor is increased, the output of the tool becomes bigger, and if it
is decreased, the output becomes smaller.
The setting of rotation speed is saved in the YZ-TH and it is to be changed by the setting
device (PC-1 etc.).

The above is one example of the tester displayed value of YZ-TH900 measured
with our tester YET-1001C.

Motor High Speed Setting (rpm)
Correlation between the motor high speed & tool's output
(
The case of YZ-TH900 with relief valve positioned at shipping)
Value rises up quick but the tightening
torque is unstable.
The high speed setting of the motor should
be decreased.
Output Value
Cut Value
Cut value is not reached or it takes time
to reach to the cut value.
The high speed setting of the motor
should be increased
