Notes on use
Do not push the wire back faster than the rewind speed of the CONSTON spring. This may loosen the wire, causing a failure.
The oil damper allows the wire to rewind slowly, which is safe. This function is ideal for slowly raising the lighting or ceiling-mounted air conditioner filters after maintenance.
It operates firmly to the end because the returning force (i.e. pulling force) is constant. Thus, motor-like behavior can be obtained.

Note 1: The return speed varies depending on the torque tolerance of the oil damper and the difference in oil viscosity due to temperature. Thus, use these values only for reference.
Note 2: Use the product at 2 cycles/min or less to prevent the oil damper temperature from rising. The life values are the number of times that will result when the product is used at 2 cycles/min or less.
