Check and fit cylinders
- Check that the protective plug on the cylinder cannot be removed by hand. If it can, take another cylinder and return the other one for filling.
- Remove the protective plugs from cylinder valves with a 23 mm U-spanner.
- Remove the safety plugs on the hand wheel couplings to the regulators and filling hoses.
- Check that the cylinder connections and hand wheel couplings are free from water, particles and other dirt. Make sure the O-rings on the hand wheel couplings are in position.
- Blow the cylinder connections by quickly opening and re-closing the cylinder valves.
Note: WARNING!Blowing noises and pressure impacts can cause hearing impairment. Always wear ear protectors when filling or emptying gas cylinders.
- Place the one-litre cylinders in the cylinder cradles, and make sure the cylinder valve's connection is in the hole on the support arm.
- Tighten and secure the tension strap around the cylinder and park the tension strap's handle in the intended slot.
