and bearing load adjustment of the spring balancers.
• Types with plastic housings must not be positioned in direct vicinity to hot air fans.
• The fixture to which the spring balancers and the fall protection device (4) are attached
must be designed with at least a safety factor of 5
(5 × [spring balancer intrinsic weight + maximum permitted capacity]).
Use the safety suspension (2) to suspend the spring balancer .
1. Ensure that the spring balancers do not slip out of the safety suspension (2), could
tighten –> retaining nut (2.1).
2. Fasten the fall protection device (4) at the suspension fixture:
