All torque values are based on 90-PSI (6,3 bar) air pressure. Torque values 
are estimated data which may differ – depending on the type of screw joint.  
 

Exchange of clutch spring 

(see picture) 

 

 

To avoid loosing individual small parts, it is recommended to 
only disassemble the machine on top of a flat work surface. 

 

 

1.  Disconnect screwdriver from air supply.  
2.  Unscrew clutch bearing 389852 C resp. gearing 389852 A (left-hand 

thread). 

3. 

For screwdriver version with gearing 389852 A:

 Disassemble lock 

ring 800304 and remove intermediate pinion 379110 together with groo-
ve ball bearing 802035 (bore thread M4 in intermediate pinion). 

4.  Remove clutch 389748 A complete. 
5.  Insert hand screwdriver into the half-round bore of the lock ring and turn 

hand screwdriver in clockwise direction, until the adjustment nut comes 
off. 

6.  Remove lock ring. 
7.  Remove clutch spring, replace with required clutch spring and reassem-

ble in reverse order. 

8.  Place clutch into clutch bearing resp. gearing and tighten it to the 

DEPRAG Screwdriver (left-hand thread). 

9.  The clutch can be adjusted again externally (see chapter 

Torque Ad-

justment

).
