2. When using the damper. please ensure that a shaft with
specified angular dimensions is inserted in the damper's shaft
opening. Also, please ensure a tight fit between the shaft
and the damper shaft's opening. Without a tight fit. the play
becomes larger in a closing motion, etc .. and the lid may not
slow down properly. Please see the diagrams to the right for
the recommended shaft dimensions for a damper.

Temperature characteristics
of the FYN-A2 series
3. Damper characteristics vary according to the ambient
temperature. In general the damper characteristics become
weaker as the temperature decreases.This is because the
viscosity of the temperature. When the temperature returns
to normal, The damper characteristics will return to normal
as well The time it takes for the lid to close is shown in the
graph to the right.

4. The damper's working angle is 120"as shown below. Rotating
the damper beyond this angle will cause the damage to the
damper. Please ensure that an external stopper is in place.

5. Because the FYN-A2 series is a self-adjusting type. the torque cannot be adjusted manually. However, by altering the viscosity of
the oil, its damper characteristics can be modified. (Please contact us, as this is a custom order.)6. The direction in which torque
is generated varies according to the model Please select the appropriate model for your purpose.

Precautions for Use
* When using the vane damper. ensure that after having fully opened the lid, move the lid to a point where free fall starts, and then release the
hand from the lid. If the lid is slightly opened and in this state the hand is released, the lid may not be able to sufficiently slow down and the lid
may be closed with force. which could result in an in jury such as getting the hand caught by the lid.
(1) Open the lid fully.
(2) Move the lid to a point
(3)
Release the hand
where free fall starts.
(the lid slows down).
(4)
If the lid is released without
fully opening it, it does not slow
down.
