5.7 Maintenance work on the machine
5.7.1 Cleaning
Clean the machine thoroughly daily.
5.7.2 Torque information
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
ges
=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.
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.

Important
It is important to ensure that the frame is also actually
pushed on the rubber stop contact surfaces and not
just the rubber elements are stretched and then spring
back again. If necessary apply light blows with a
hammer to knock the rubber stops downwards.
