ATTENTION!
Risk of material damage posed by use of incorrect screws!
Cross wipers/carriages may become damaged.
• Safe functionality of the steel plugs is only guaranteed with the use
of DIN 912/ISO 4762 high-headed screws to fasten the guide rails.
• Any markings on the screw-head must not be raised.
Disassembly
Once properly installed, the steel plugs are fixed into the guide rail fixing holes
very firmly. We therefore recommend that disassembly is carried out using an
appropriate extracting device. A standard Allen screw is suitable for this purpose.
For recommended screw and core hole diameters, see Table „Dimensions of MRZ
steel plugs" on page 70.
1. Make a punch mark in the centre of the plug and then drill through the plug at this
point using a portable drill. Take care not to damage the guide rail fastening screw.
The drill diameter should be selected in accordance with the Allen screw used.
2. Use a thread cutter to cut a thread into the plug. Remove any swarf from the thread.
3. Screw the Allen screw into the plug by hand until the tip of the screw comes into
contact with the head of the guide rail fastening screw.
