Replacing the pressure bottle
Do not use tools to tighten the hand screw at the air
cylinder connection.
Partially emptied air cylinders must be recharged or
replaced before the next use of the extinguisher.
The threads of air cylinder and regulator must be free of
dirt and debris. Clean if necessary, but do not lubricate.
Check the condition of the O-ring at the pressure
regulator. Replace it in case of cracks or loss.
Do not open the cylinder valve before the next use.
Never overfill an air cylinder. Maximum pressure: 300 bar.
Use approved pressure bottles of same size only.
If the air cylinder is opened by mistake, close it again and
discharge the pressure by opening the vent valve of the
lid. The remaining capacity of the air cylinder is still
sufficient. Refill or replace the bottle in case of recurrence.
If necessary, clean the threads of pressure tank and air cylinder
connection with compressed air or a small brush. Do not
lubricate. Check the condition of the O-ring before screwing the
regulator to the compressed air cylinder.
Pressurized vessels represent significant hazard for user and
vicinity in case of negligence or mishandling. Always treat filled
air cylinders and charged extinguishers with due diligence.
