Strength classes for all bolts with untreated, non-lubricated sur-
faces.
The values indicate 90% utilisation of the tesile yield strength; at
a friction coefficient of µ =0.14.
total
Tighting torques can be verified with torque wrenches.
The specified values do not apply when using lubricant MoS2.
Renew self-locking nuts after each disassembly.
Important
5.6.3 Bolted connections
When using vibrating machines, it is important that the bolted
connections are checked for tighteness at regular intervals. Ob-
serve tightening torques.
5.6.4 Checking rubber buffers
Check rubber buffers for cracks and other damage as well as for
tighteness and replace immediately if damaged.

Tension the V-belt by shifting the engine bracket (3)
To be noted is that the bracket (3) moves and not only
the buffers are elongated. In this case, the buffers
should be tapped forward lightly with a hammer.
Important
Deflection X: About 15 mm
•
Ensure uniform buffer tension
•
Tighten rubber buffers
•
Crank the drive manually, recheck deflection and correct if
necessary
•
Fit V-belt guard
Do not start engine without V-belt guard, risk of in-
jury.
Danger
•
After about 25 operating hours, recheck the V-belt tension and
retension if necessary.
