The tightness categories relate to bolts with untreatet, unlibri-
cated surface.
The figures result in 90% exploitation of the limit of elasticity for a
friction coefficient µ =0.14.
ges
Use a torque wrench to check that the tightening torques are
observed.
The figures indicated do not apply if lubricant MoS2 is used.
Hinweis
Self tighted nuts have to be replaced after every disassambly.
5.7.3 Screw connections
With vibration equipment, it is important to check the screwed
connections periodically to ensure that they are screwed tight.
Observe tightening torques.
5.7.4 Checking rubber buffer

It is important to ensure that the frame is also actually pushed on
the rubber buffer contact surfaces and not just that the rubber
61
elements are stretched and then spring back. If necessary, apply
106
light blows with a hammer to knock the rubber buffers forward.
– Both buffers should be equally pre-tensioned.
173

269
–
Crank the drive manually and recheck tension and correct if
368
necessary.
