Question about PRO 6 litres

maintenance-free, has a pressure gauge, if no longer in the green range, replace it. lasts for years. i then recommend a private exercise with it in the garden, e.g. fire bowl and then recycling. greetings from a member of the fire brigade.

Check the pressure on the pressure gauge every year, otherwise no maintenance is necessary. For safety reasons, I would replace the fire extinguisher after 10 years, as it doesn't cost the earth.

There is no expiry date. You just have to keep an eye on the pressure (there is the pressure gauge, the needle of which must always be in the green zone).
I'm not sure, but it seems to me that it has to be sent to the Swiss importer for maintenance (filling in case it runs out over time or use).

unfortunately i don't know. the fire extinguisher arrived defective, damaged in transit, and was not replaced. since then it has been lying defective in the cellar, too bad....
