Maintenance:

Use a soft, lint-free cloth or gauze to clean the surface of dust and dirt.

Tips:

• The medium pressure tube can be equipped with quick connector. When using the quick connector, the plug part is connected to the gas supply valve. The socket assembly position is near the decompression valve. When the plug is not inserted into the socket, the cylinder valve is opened and the socket is airtight. The quick connector automatically locks when there is compressed air in the middle pressure tube, if you want to pull out the quick connector, you must first pressure the medium pressure tube;

• Do not immerse the medium pressure tube in water. Only use a soft cloth to scrub. Care must be taken not to immerse the liquid in the hose, especially in winter. After entering the water, it will cause ice inside the hose, causing unnecessary damage and danger;

• Equipment must be inspected at regular intervals, and always after use in practice or in an emergency. It should never be stowed when wet or dirty.
