sure the proper bit is suitable for the head of the fastener.
3. The torque limit is determined by the tension of the coil spring housed in the torque adjustment nut.
4. Rotate the torque adjustment nut to set the torque limit. Turn clockwise to increase torque and counter clockwise to
decrease torque.The scale adjacent to the Torque Adjustment Nut is a reference guide. The torque output from the
driver can change depending on various fastening factors like friction, type of joint, and the type material being used like
a washer.
5. Plug in transformer and check power indicator. If it is not on, check fuse in the transformer.

HOW TO REPLACE THE CARBON BRUSH
WARNING:
When replacing the carbon brushes, detach the cord from the driver body or unplug the transformer from the
power outlet.
1. The carbon brush piece is 1/3" long when new. Change the pair when they are worn to about half the original length.
2. Insert a flat tip screwdriver into the slot in the carbon brush cap and unscrew the cap.
3. Replace the worn brushes with new pair. The contact surface of the brush is concave. Insert the brush so that the concave
end properly aligns with rounded surface of motor comutator.

2. Only use the transformers listed in the Mountz catalog for appropriate K-Series driver model (If you have any questions
regarding the appropriate transformer set-up, contact Mountz Customer Service Department).
3. Operate under safe conditions. Do not place in operation where such objects as hair, strings, clothing, etc. can become
tangled in the rotating bit.
