4. Damper characteristics vary according to the ambient
temperature. In general, the damper characteristics become
weaker as the temperature increases, and become stronger as
the temperature decreases. This is because the viscosity of the
oil inside the damper varies according to the temperature. When
the temperature returns to normal, the damper characteristics
will return to normal as well. The changes in the time it takes for
the lid to close are shown in the graph to the right

5. The damper's working angle is 110
°
, as shown below. Rotating the damper beyond this angle will cause damage to the damper. Please
ensure that an external stopper is in place. The working angle is based on the width across flat for fixing, located towards the rear end of
the main body. The position where the rotation is complete is at 90
°
with respect to the width across flat.

6. The FYN-D1 series is a fixed type: its torque is non-adjustable. However. a customized order for a torque between the range of 2
~20N·m is possible by changing the oil viscosity.
7. The direction in which torque is generated varies according to the model. Please select the appropriate model for your purpose.
