Instructions for Use – Zero Gravity Balancers
INSTALLATION
CAUTION!
1. Using the safety suspension (2), fasten the zero gravity balancer to a suspension structure that
provides adequate stability.
2. Make sure that the balancer cannot slip out of the safety hook (2) => tighten lock nut (7228,
7235/36, 7245) or close the hook's safety catch (7230, 7241, 7248, 7251, 7261).
3. Fasten the anti-crash safety device (3) to an independent suspension structure (other than that of
the safety suspension), making sure that
• the range of movement of the zero gravity balancer is not in any way restricted,
• the falling distance does not exceed 100 mm if the balancer drops down!
ADJUSTING THE CABLE LENGTH
If the zero gravity balancer is delivered with a cable wedge fitted to the cable, it is possible to use
the excess cable length available:
1. To lengthen the cable, pull it through the cable wedge (6), making sure that a minimum distance
of 100 mm is maintained between the cable wedge (6) and the cable clamp (5) (see illustration
below).
2. Following length adjustment, press the ferrule (7) supplied in place on the cable.
3. Cut off the cable end extending beyond the ferrule (7).

ADJUSTING THE CABLE STOP BUFFER
CAUTION!
1. Attach an appropriate load and pull out the cable to the desired posi-
tion.
 Only specially authorized and trained persons are permitted to install
the zero gravity balancer and make cable length or load adjustments.
 Balancers with a plastic housing must not be installed in the immedi-
ate vicinity of hot-air blowers.
 If the zero gravity balancer is to be operated with welding tongs, insu-
lated suspension is required to provide isolation from leakage cur-
rents. Be sure to observe your national/local regulations.
 The suspension structures to which the zero gravity balancer and the
anti-crash safety device are to be fitted must be designed with a safe-
ty factor of at least 5 (i.e. 5 x [own weight of balancer + maximum
permissible load]).
