.
*
The friction coefficient of 0.10 applies to oiled sheets, cast iron,
hardened surfaces, greased threads, etc. The higher value of 0.13
applies to dry sheets.
Torques for bolts and nuts with serrated lower edges 10% extra, such
as:
•
Tensilock (K100)
•
Whizlock.
Exceptions to this table are listed in the parts and/or instruction
manual.

Nuts and bolts could become loose through vibrations. Check the nuts
and bolts regularly to prevent damage the machine and possible
injury, especially after maintenance.
Check all bolt and nut connections:
Turn all nut and bolt connections up to the point as given in the
chart below:
•
