● In certain cases it is not possible to screw the secondary
part with the machine directly, as additional materials like
distance plates, thermal grease and so on, are among sec‐
ondary part and machine. Then a sufficient fastening of the
screw connection must be ensured by the machine manu‐
facturer.
● The effect of liquid screw lock is damaged by loosening or
re-tightening of screws (e.g. due to torque tests) and must
be renewed.
● Use all fastening points to fasten the secondary part.

Tab. 13-3: Tightening torque for the fastening screws of the primary parts
The screw-on surfaces and stop faces must be cleaned and be free of grease
before the primary parts can be screwed on the machine construction. Se‐
cure all screwed connections with screw connection, e.g. Loctite 243.
Mounting instructions:
1. Preparing the threades holes and screws for assembly
2. Fasten the primary part with screws 1, 2, 3...n until the primary part lies
on the slide.
Fasten screws - from inside to outside - 1, 2, 3 ... x with nominal tighten‐
ing torque:
