Spring shafts
Installation
Mount guides and bearings. Insert spring shaft in the bearing and fasten. Attention! For this purpose, the direction must be observed. The arrows on the housings point in the rolling shutter or rolling grill direction. Then install rolling shutter/grill and screw on with the hangers on the spring housing. The guide tubes of the spring housing have 6 holes each left and right, on one side for clamping the hook wrench (on the other side for insertion and removal of the locking pin).
The hook wrench is hooked in and pulled from top to bottom. The number of holes is counted while doing this (six holes = 1 revolution). Marking on the guide tube and axle tube facilitates the counting. When tightening or readjusting the hook wrench, the locking pin is removed or inserted. This process, the tightening and readjusting is repeated until the required spring tension has been reached.
