5.4 Adjusting the spring balancer

The spring balancers can be finely adjusted
using the adjusting screw (2) on the housing
(see Fig.).
Before adjusting the bearing
load, attach the load with the
rope fully pulled in.
Adjustment in direction "Plus"
(+) increases the bearing load.
Adjustment in direction
"Minus" (-) reduces the
bearing load.
The correct setting is achieved
when the attached load can be
pulled easily to the required
position and, on releasing it,
returns to its initial position.
Fig. 6: Spring balancer
Insert the Allen key in the adjusting screw (2).
Use the Allen key to set the required setting
within the permissible adjusting range. The
adjusting screw (2) acts on the spring catch (1)
which is provided with a marking on the
outside. The adjustment can be observed
according to this marking.
