LUBRICATION
Speed variators are supplied with lubrication oil for assembly position B5, for other positions it will be necessary to
add oil, see following table.
ACCESSORIES
Gravitational indicator
The gravitational indicator must be inserted into the handwheel and with a numerical scale it shows a reference
link to the speed. Set the indicator moving the two hands to zero and put it into the handwheel after setting the
variators to minimum speed.
The gravitational indicator doesn’t work with vertical handwheel
axis.
USE AND MAINTENANCE
The screws under the handwheel are well adjusted, don’t touch
them. Don’t adjust the handwheel when the motor is off, this can cause internal
breaking. Speed variators are filled with oil, check the level
before running. After the running-in the oil must be changed, check
the level periodically. The temperature after the running-in can reach
50/55°C over room temperature.
When the variator is supplied without motor make sure that the assembled one is at least “normal”
class quality and the connection is not forced. Speed variators are supplied with closed oil
plugs.When the variator is used for continuous work replace the closed plug with the supplied breather
plug. |
