DIVATOR.mAInTenAnCe.AnD.RepAIR.mAnuAl. 1. InTRODuCTIOn Divator is a self-contained underwater breathing apparatus (SCUBA). The apparatus is designed to suit every category of diver that works under water with air. Environmental factors such as cold, heat, or type of water (chemical compounds, salt or ice) have little or no effect on the operation of the apparatus.
Parts that are secured with locking compound must be well cleaned and free from grease before the locking Only holders of a valid Interspiro Service Cer- compound is applied. It is advisable to use an alcohol- tificate for the equipment in question may carry...
