The outer dimension and mounting method of the crank lever which is commonly used for the Spatial Filter type Speed Detector such as [LC1100/2100/3110/3210], [SF660B/760B], and [DL2100/2200], etc. are as follows.

Please attach the right side of [crank lever "S type"] at the very beginning. The lever position can be moved to any angle by pulling up the lever after temporary attachment of the screw and rotating it.

At first, rotate the level while pulling out and adjust the S type crank lever and L type crank lever facing reverse from each other. This process enables to prevent the mechanical interaction between levers.
