3. When connecting the rotating shaft to other parts. please

ensure a tight fit between them. Without a tight fit.  the lid

will not slow down properly when closing.

4. The  time  it  takes  for  a  lid  with  a  damper  to  close

variesaccording  to  the  ambient  temperature.  As  the

temperature  increases.  it  takes less time. and as  the

temperature  decreases.  it will take longer for the lid to

close. This is because the  viscosity  of the oil inside the

damper changes according to the temperature. When the

temperature returns to normal, the required time will return

to normal as  well.  The temperature characteristics  are

shown in the graph below.

5. The  standard  for a  damper's  working  angle  is  180

° 

with

respect to the main body's attachment flange. Rotating the

damper beyond this angle will cause damage to the damper.

Please make sure that an external stopper is in place.

<FYN-M1-R> 

Position of the rotating shaft when 

the damping process is complete 

6. The direction in which torque is generated varies according

to the model. Please select the appropriate model for your

purpose.
