Adjusting the spring tension:
WARNING!
Danger of impact and crushing!
During the barrier movement, energy is saved in the springs. The springs are
not tight and thus energy-free only in barrier position OPEN.
 Mount and dismount the springs in barrier position OPEN only. If
necessary move the barrier manually into position OPEN.
WARNING!
Risk of crushing
During the barrier movement crushing points arise at many points of the
barrier mechanics.
 Before installation, maintenance or repair work at the barrier mechanics
turn the power supply off and secure it against unintentional restarting.
