The tightness categories relate to bolts with untreatet,
unlibricated surface.
The figures result in 90% exploitation of the limit of elasticity for a
friction coefficient µ =0.14.

Use a torque wrench to check that the tightening torques are
observed.
The figures indicated do not apply if lubricant MoS2 is used.
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
Check the rubber buffer for cracks and fractures and for a tight fit;
replace immediately if damaged.
