  • Page 48 The filters must be replaced if they exhibit: ● visible contamination ● mechanical damage ● contact with water If none of the events occurs, the filters must be replaced after 12 months at the latest. Checking the filters The dust filter contamination can be tested from the outside by inspection through the transparent filter fastener. To check the condition of the filters more precisely, the filter fas- tener must be unscrewed. Note: Once a hydrophobic filter has been taken out it must not be re- placed. Recommended tools ● Coin for turning the filter fastener ● Tweezers for removing and inserting the hydrophobic filter and O-ring Changing the filter NOTICE! Risk of contamination New filters, i.e. filters not yet used, must be handled carefully to prevent mechanical damage.
