W gear units
Running-in
period
Spiroplan

and helical-worm gear units require a running-in period of at least 24 hours
before reaching their maximum efficiency. A separate running-in period is required for
each direction of rotation if the gear unit is operated in both directions of rotation. The
table displays the average power reduction during the running-in period.
5.2
Startup of helical, parallel shaft helical and helical-bevel gear units
There are no special startup notes that have to be observed for helical gear units,
parallel shaft helical gear units and helical-bevel gear units, if the gear units have been
mounted according to the section "Mechanical Installation."
Note: The direction of rotation for the output shaft has been changed from CW to CCW
for helical-worm gear units S..7 series compared to the S..2 series. Switch two motor
feeder cables to change the direction of rotation.
