Maintenance
NOTICE
Damage to components!
The gas detector contains components at risk of charging.
► Before opening the gas detector to exchange the sensor, make sure that the
operator is earthed in order to prevent damage to the gas detector. For example,
earthing may be ensured by an ESD workplace (electro static discharge).
1. Switch off the gas detector.
2. Loosen 6 screws (Torx T8) on the rear housing cradle.
3. Carefully pry apart the front and rear housing cradles (e.g. with a coin).
NOTICE
Damage to the sealing contours!
Tools with sharp edges may damage the sealing contours.
► Do not use tools with sharp edges to remove the rear housing cradle.
