# Pressure and / or Torque Adjustment

The torque of hydraulic torque wrenches is proportional to the pressure. This is why before tightening or loosening bolted connections the maximum pressure of the machine and thus the maximum torque of the torque tool must be adjusted.

1. Do not place the hydraulic tool on either bolts or nuts.

2. Switch on the motor by pushing the I-button on the remote control and keep the I push-button pressed down – the tool piston extends.

3. After reaching the end position of the tool piston, the maximum pressure of the system can be increased by turning the adjustment knob (a) on the pressure adjustment valve (b) clockwise until the required pressure is reached. The current system pressure is displayed on the manometer.

4. By releasing the I push-button, the tool piston retracts.

5. Checking the setting: after reaching the end position a second time, press the I push-button again in order to extend the tool piston completely and to keep it until the maximum pressure is reached.

6. Bring it below the desired pressure mark and turn the adjustment knob (a) on the pressure adjustment valve (b) clockwise again to reach the required pressure point.

7. When the required pressure is reached, the setting is secured by tightening the wing nut (c) on the pressure adjustment valve (b).

Please check torque pressure chart of each tool carefully for setting the pressure. Different size tools will deliver different torque at same pressure.
