Wichtige Hinweise
Die Sicherheit des Gerates muB nach einer Reparatur oder Uberpriifung
erhalten bleiben. Es diirfen deshalb keine konstruktiven Merkmale des
Gerates sicherheitsmindernd verandert werden (z.B. missen
Abdeckungen ordnungsgemaB angebracht sein).
Ersatzteile mussen hinsichtlich ihrer Daten und ihrer Merkmale dem
getauschten Teil entsprechen, damit die Sicherheit des Gerates nicht
vermindert wird. Verwenden Sie deshalb nur Original-Ersatzteile.
Important note
The unit must remain safe after repair or checking. Therefore, no design
features of the unit may be altered which would result in a reduction of
safety (e.g. covers must be properly replaced).
With regards to their data and technical features, spare parts must
correspond with the replaced part, so as not to reduce the safety of the
unit. Therefore, only use original spare parts.
Avvisi importanti
La sicurezza dell’apparecchio deve rimanere conservata anche dopo
una riparazione o un controllo. Percid non é permesso di variare
connotati costruttivi dell’apparecchio in modo che non garantiscono la
sicurezza originaria (p. es. gli schemi di protezione devono essere fissati
a regola d’arte).
| pezzi di ricambio devono corrispondere al pezzo da sostituire nei loro
dati e nei loro connotati per garantire la stessa sicurezza
dell’apparecchio. Usate percio solo ricambi originali SABA.
Recommandations importantes
L’appareil doit remplir les mémes conditions de sécurité aprés une
réparation ou une révision. Aucune caracteristique de construction de
l'appareil ne doit donc étre modifiée de telle sorte que la sécurité de
l'appareil en soit diminuée (par ex., les couvercles doivent étre remis en
place correctement).
Les caractéristiques et les propriétés des piéces de rechange doivent
coincider avec celles de la piéce qui est remplacée afin de ne pas
réduire la sécurité de l’appareil. N’utilisez donc que des piéces de
rechange d’origine.
