Operating the Tool

1. Attach cord to the K-Series Driver. Make sure notch in plug lines up with the notch on the socket. Tighten knurled ground 

ring. Attach cord to the transformer. Make sure notch in plug lines up with the notch on the socket.  Tighten knurled 
ground ring.  

2. Select a bit. Retract the bit collar. Insert the bit and release the retracted collar. To avoid damaging fasteners, make 

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.

STC 30 Plus Transformer -

Features a HIGH & LOW speed button. Select the appropriate speed for your 

application. 

6. Turn driver on and check for proper rotation. FOR-clockwise, REV-counterclockwise.
7. To apply torque, squeeze the lever (Push-to-Start models - place light downward pressure on the nose of the driver). The 

driver will automatically stop when the preset torque has been reached.

8. To remove the screw, turn the FOR/REV switch to REV.

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.

CARE

1. The K-Series screwdrivers are a precision torque control instrument and should be handled with care at all times.
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.  

4. Keep away from moisture.  Never use in high humid, moist or damp environment.
