The built in snubbers must be adjusted when the suspended equipment has its working condition. The adjustment is done by turning the upper part of the housing until a distance (A) of 2 mm is reached between the house and the snubbing cushions.

The height (H) of the mount should be between 105 – 115 mm, depending on the load.

With correctly adjusted snubbers the maximum movement will be ± 4 mm in all directions.
