8.3. MAINTENANCE OF THE MAGNUM LIGHT SPEED SOFTPACK

Throughout the dismantling – or assembly process never use violence or bring tension on the acti-
vation cord! All steps must be made smooth. Otherwise the rocket will activate!
During your work put the shooting out opening always away from yourself and check before star-
ting work that there are no persons or object in shooting out opening! If possible, all works should
be done outside.
Please note, that for all works done yourself are without warranty of function or security, besides
they have been proved by anybody authorized from Junkers Profly GmbH.
All work done by yourself are at your own risk and responsibility.
The rescue system is free of maintenance works (if used appropriately) for the duration of 6 years.
After activating the system or after this span of 6 years, the rescue system has to be sent to the
manufacturer.
This check may only be executed by the manufacturer.
For every damage during the use, which might endanger the safety of the product, Junkers Profly
assures repair of the rescue system and its reduction into the original condition. Every damage
must be communicated to Junkers Profly.
It is recommended to change all fixing cords out of Kevlar or Polyamide after 12 years or after 18
years.
