The listed speed and impact-rate values describe each output setting; trigger pressure controls operating speed. Output settings should not be treated as calibrated final tightening torque values. Where a specified tightening torque is required, verify the final torque with an appropriate torque wrench.
Operating Controls
- Output Selection – Use the mode control to select one of the two forward output levels.
- Variable-Speed Trigger – Press the trigger lightly for a lower speed and increase pressure to increase speed. Release the trigger to stop operation.
- Forward and Reverse – Move the direction selector to change rotation direction. The centre position locks the trigger.
- Continuous Reverse – In continuous reverse mode, the tool runs in reverse while the trigger is held.
- Reverse Auto-Stop – Select reverse and enable the auto-stop function using the control panel. The tool stops reverse rotation when the fastener loosens and resistance drops.
