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.
total
Use a torque wrench to check that the tightening torques are ob-
served.
The figures indicated do not apply if lubricant MoS2 is used.
Self tighted nuts have to be replaced after every
disassambly.

5.9.3 Screw connections
With vibration equipment, it is important to check the screwed
connections periodically to ensure that they are screwed tight.
Observe tightening torques.
5.9.4 Checking rubber buffer
Check the rubber buffer for cracks and fractures and for a tight fit;
replace immediately if damaged.

It is important to ensure that the frame is also actually
pushed on the rubber buffer contact surfaces and not
just that the rubber elements are stretched and then

spring back. If necessary, apply light blows with a ham-
mer to knock the rubber buffers forward.
–
Both buffers should be equally pre-tensioned.
–
Tighten nuts.
–
Crank the drive manually and recheck tension and correct if
necessary.
Do not start the engine without V-belt guard. Dan-
ger of injuries.

–
Replace V-belt guard.
Check the tension of the V-belt after 25 op. hrs. again.
Adjust the tension if necessary.
