Never run the gear unit when the shrink disc protective guard is not fitted.
5.1.5 ANCHORING THE TORQUE ARM
For shaft-mounting solutions the gear unit can be equipped with a torque arm on request.
This device, which is made of electrowelded steel and equipped with damper bushes, assures the
highest guarantees of functionality of the assembly because it is designed and sized specifically for
the job.
5.1.6 GEAR UNIT EQUIPPED WITH MANIFOLD FLANGE
Thoroughly clean and degrease the mating areas between the gear unit flange and
driven machine flange. The correct execution of this procedure is essential for safe torque
transmission. Do not use solvent with dirty rags to degrease the surfaces.
Do not use molybdenum disulphide or any other type of grease, as this would
significantly lower the friction coefficient in the contact area and therefore impair the
functionality of the coupling.
Tighten the bolts fully down, working in a crosswise sequence and applying the
maximum tightening torque shown in the chart by means of a torque wrench.
