WARNING
Danger of poisoning from toxic vapors
Igniting and heating synthetic operating fluid generates toxic vapors. Danger of poisoning if inhaled.
►
Observe the application instructions and precautions.
►
Do not allow tobacco products to come into contact with the operating fluid.
NOTICE
Destruction of the turbopump due to incorrect operation when filling with operating fluid
The operating fluid filling quantity depends on the selected spatial position of the turbopump. The fill-
er screws are located at clearly marked positions on both sides of the operating fluid pump of the tur-
bopump. Confusion with other screw plugs leads to impurities, damage to the turbopump, up to and
including its destruction.
►
Only fill the turbopump with operating fluid after mechanical installation.
►
Fill the turbopump with operating fluid via one of the filler screws marked with an oil can symbol
only.
