shaft lines should be kept concentric when
the coupling is connected with a motor. The
installation error should not bemore then
the tolerance value of the coupling.
When the output shaft is installed with the
coupling or belt wheel, they should be pressed
into the screw hole on shaft end, or assembled
by heating. No hammering should be done on

set is not suited to work in the environment
of above 40 C, especially more than 45 C when
the temperature goes up.
When the variator starts to work (without
load), the temperature rise higher than normal,
up to 40~50 C above the environment temperature.
After 60-80 hours running, the temperature
will decrease gradually. Finally, the temperature
will be about 20 C higher than surrounding
and keep stable. The high temperature at beginning
do not damage any parts of variator and do
not effect its service life. (Suggestion:
running without load at first.)

up the oil level before use.

leaving the factory. When it starts to work
up to 1000 hours for the first time, its lubricating
oil should be replaced.
lubricating oil level inside the speed variator
should be kept at the height of one-third
in the oil scale. Users should usually check
up the height of oil level.
