STARTING
5.1 Series RS, RT
The worm gearbox originates the following rotations of input and output shafts, with worm shaft upwards:
•
inverse rotation
one-stage gearboxes (RS, RT);
•
original rotation
helical/worm gearboxes (RA, TA);
•
inverse rotation
two-stage gearboxes
(RS/RS, RT/RT).
Worm shaft downwards: opposite situations.
5.2 Series RC, RD, RP, XA, VR
The helical gearbox and the variator originate the following rotations of input and output shafts:
•
inverse rotation
odd-stage gearboxes (one, three, etc.)
and variators with odd-stages;;
•
original rotation
even-stage gearboxes (two, four, etc.)
and variators without stages or even-stages.
6 INSPECTIONS AND MAINTENANCE
6.1 Intervals
Although the units are no-load run tested in the factory before despatch, it is advisable not to run them at maximum load
for the first 20-30 hours to allow proper running in.
For variators, run throughout the full speed range at reduced load before the full load is applied.
The units are delivered already filled with synthetic long-life oil: no servicing or refilling within the average lifetime of
15,000 hours for operation according to SF1.0.
Refer to the Catalogues as appropriate to the right definition of Service Factor.
Variators Series VR run dry and bearings are lifetime grease packed; thereore, there is no part needing periodical
maintenance, the friction ring replacement excepted on normal wearing conditions.
6.2 Maintenance Servicing

Periodically check the state of seals and possible evidence of lubricant leakages.
If lubricant replacement or topping is required, do not mix with mineral based lubricants.
Variation section, dry running and with lifetime grease-packed bearings, does not require any periodic servicing, excepted
the friction ring replacement on normal wearing conditions.
