4.2.9.2 Alignment of the coupling
Any differences in the height adjustment clutch is aligned under the machine feet inserts appropriate shapes
made from sheet steel.
After alignment of the coupling halves and tighten the machine screws fixing the base must be the coupler
checked.
Manufacturer’s tolerances connections should be reduced as much as possible, because the slightest glitch
can cause a disproportionate increase in load bearing and coupler.
Imprecise mechanical connection of the both machines, sets vibrates and roared, damaging the
coupler and bearings.
CAUTION
After starting the machine, and after reaching operating temperature machines (sets), it is necessary
to again check run out of the coupling halves according to paragraph
4.2.9.1
Failing to values listed in Tab. 2 it is necessary to make a correction according to 4.2.9.2 .
