Motor High Speed Setting (rpm)

​The above shows the influence of the motor speed on the torque output, this is an example of the YZ-T900 tested on the static torque tester YET-1001C.

​Relief valve adjustment:

Adjusting the tool's output with the relief valve, mechanical adjustment on the impulse mechanism.
Always take off the battery when adjusting the torque output with the relief valve on the impulse mechanism.
Use the TF pin (2mm x 90mm, supplied with the tool in the box).
Rotate the main shaft until the adjust screw is visible, turn left to increase the torque output and turn right to decrease the torque output.
