1. Lås op: Pull down the unlocking adjustment wheel located at the base of the handle. This disengages the locking mechanism, allowing for torque adjustment.
2. Justere: Rotate the handle to align the desired torque value with the indicator line on the scale. The scale displays values in both Newton-meters (N.m) and inch-pounds (in-lbs).
3. Låse: Once the desired torque is set, release the unlocking adjustment wheel. It will spring back into place, locking the setting. Ensure the wheel is fully engaged to prevent accidental changes during use.

The torque scale is clearly marked for easy reading. For example, to set 0.8 N.m, rotate the handle until the 0.8 mark aligns with the indicator.

4. Betjeningsvejledning

Follow these steps for proper operation of your GOYOJO GMS8 torque screwdriver:

1. Prepare the Fastener: Ensure the fastener and the mating thread are clean and free of debris.
2. Placer værktøjet: Place the installed bit onto the head of the fastener. Apply steady, downward pressure to keep the bit engaged.
3. Påfør moment: Rotate the screwdriver handle clockwise (for right-hand threads) smoothly and steadily.
4. Listen for the Click: Continue rotating until you hear and feel a distinct "click." This indicates that the preset torque value has been reached.
5. Stop Applying Force: Immediately stop applying rotational force once the click is heard. Further tightening will result in over-torquing.
6. Fjern værktøjet: Carefully remove the screwdriver from the fastener.

For left-hand threads, rotate counter-clockwise. Always ensure the bit is fully seated in the fastener head to prevent cam-out and damage.
