SAFETY INSTRUCTIONS – ACCIDENT PREVENTION
CAUTION!
No changes may be made to the balancer or its accessories without the express written consent

must previously have been informed about the potential hazards involved in performing these
tasks.
The balancer may only be serviced and repaired by qualified personnel that has been specially
trained or authorized by the manufacturer.
Taking the balancer apart is extremely dangerous and therefore strictly forbidden.
The fixtures to which the zero gravity balancer and the anti-crash safety device are to be fastened
must provide sufficient stability!

Never operate the zero gravity balancer without the safety equipment supplied (anti-crash safety
36
device) in place.
