2. Loosen the screws on the cable clamp (5), set the desired cable length, then retighten the
screws.
ADJUSTING THE LOAD
CAUTION!

 To make load adjustments, a 6-mm Allen wrench is required.
 Press the Allen wrench into the shaft (8), then rotate wrench to set
the load as appropriate within the approved adjusting range.
 X = maximum number of turns permitted in the "minus" direction,
starting from the factory-preset "maximum load" setting. (=> page 18)

 To make load adjustments, the following tools are required:
17-mm socket wrench
 Apply the wrench to the adjusting screw (10), then rotate to set the
load as appropriate within the approved adjusting range. However,
the following restrictions must be observed:
CAUTION!
NOTICE!

 Prior to making load adjustments, attach your working load to the fully
retracted cable.
 All zero gravity balancers are factory-preset to "maximum load".
 Adjusting in the "minus" (-) direction reduces the load (spring tension).
 Adjusting in the "plus" (+) direction increases the load (spring tension).
 The correct setting is achieved when the suspended load can be effort-
lessly pulled into the desired position and remains in this position when
set free.
 We recommend you to document your settings in writing in order to en-
sure that both the permissible "maximum load" and "minimum load"
limits are always respected when making readjustments. Regarding
these limits, it is essential to pay attention to the type-specific preload
information provided in the "X" column of the tables on pages 18 and 19
below. Failure to comply with this requirement can destroy the spring
inside the housing!
 7228 only: Upon pressing the shaft (8) inwards, you'll feel the spring
preload acting on your adjusting tool, so be sure to hold the tool firmly!
For types 7235/36, 7241, and 7251: Setting the balancer to "minimum load"
is permitted only if the cable has been fully retracted or pulled out no
more than 1.0 m.
For type 7261: Setting the balancer to "minimum load" is permitted only if
the cable has been fully retracted or pulled out no more than 0.5 m.
The adjusting screw (10) acts on a transmission gear which in turn acts
on the shaft (8). To let you check at a glance how many turns of the shaft
(8) have been made, the cover disk (12) attached has been color-marked
next to the shaft (8) (in the case of type 7248, the disk has a small hole).
