General Hints to Danger STOP D A N G E R ! With assembly and disassembly of the clamping set it has to be made sure that the entire drive train is protected against unintentional engagement. You can be seriously hurt by rotating parts. Please make absolutely sure to read through and observe the following safety instructions. • All operations on and with the clamping set have to be performed taking into account "safety first". • Please make sure to disengage the power pack before you perform your work at the clamping set. • Protect the power pack against unintentional engagement, e. g. by providing hints at the place of engagement or removing the fuse for current supply. • Do not touch the operation area of the machine as long as it is in operation. • Please protect the rotating drive parts against unintentional touch. Please provide for the necessary protection devices and caps. Proper Use You may only assemble and disassemble the clamping set if you • have carefully read through the mounting instructions and understood them • and if you are authorized and have proper skills The clamping set may only be used in accordance with the technical data (see CLAMPEX® catalogue). Unauthorized modifications on the clamping set are not admissible. We do not take any warranty for resulting damages. To further develop the product we reserve the right for technical modifications. The CLAMPEX® clamping set described in here corresponds to the technical status at the time of printing of these mounting instructions.

Castrol 4 in 1 or Klüber Quitsch Ex). ! C A U T I O N ! Do not use oils and greases with molybdenum disulphide or high pressure additions as well as slide grease pastes. • Detach the screws slightly. To make the assembly easier, fix the pressure rings in the front and in the back via the respective forcing thread by 2 clamping screws (see picture 3 and 4). Insert clamping set KTR 400 between shaft and hub. picture 3: fixing of the front pressure ring picture 4: fixing of the back pressure ring • Remove the clamping screws used for the fixing and screw them into the threads of the back pressure ring. • Slightly tighten the clamping screws manually and align the clamping set with hub part. • At KTR 400 please make sure that the pressure rings are parallel to each other and in an angle of 90° to the shaft/hub. • Tighten the clamping screws evenly and crosswise. Increase the tightening torque step by step. This procedure must be repeated until the tightening torque indicated in table 1 is reached with all clamping screws.

Loosened or falling drive parts can cause injuries to persons or damages to the machines. Safe the drive parts before the disassembly. • Loose all clamping screws evenly one after the other and unscrew them. • Screw the clamping screws into the forcing threads of the front pressure ring (component 1) (see picture 5). • Tighten the clamping screws evenly and crosswise. Increase the impression torque step by step until the front pressure ring (component 1) and the external ring (component 3) are separated. • Screw the clamping screws into the forcing threads of the external ring (component 3) (see picture 6). • Tighten the clamping screws evenly and crosswise. Increase the impression torque step by step until the back pressure ring (component 2) and the external ring (component 3) are separated. • Remove the unscrewed clamping set between shaft and hub. picture 5: disassembly of the front pressure ring picture 6: disassembly of the back pressure ring !
