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.

1) In the FYT-H1 (H2) and FYN-H1 (H2) series, the amount
of generated torque can be adjusted with the adjustment
knob located towards the rear of the main body. Insert a
screwdriver in the minus groove to turn.
2) Turn the adjustment knob in the H direction to increase torque.
3) Turn the adjustment knob in the L direction to reduce torque.
4) Do not turn the adjustment knob more than 360
°
. Turning
the knob more than 360
°
causes the adjustment shaft to
slip out. resulting in oil leakage.
5) Once the adjustment is complete, secure with a lock
screw. Using the damper without securing it may result in
fluctuating torque.
