To adjust the torque on these Twin Blade Impulse
Wrenches, proceed as follows:
1. Remove the Adjustment Hole Plug.
2. Rotate the Drive Shaft until the Torque Adjustment
Screw is visible in the opening. There is no colored
paint in the head of the Torque Adjustment Screw.
3. Using either a 2 mm or a 1.5 mm hex wrench, rotate
the Adjustment Screw clockwise to increase the torque
output and counterclockwise to decrease the torque
output. Do not rotate the Oil Plug.
Make all final adjustments at the job.
4. Replace the Adjustment Hole Plug.
