Using your Volta Tornado U4501 or U4501P vacuum cleaner hose is easy. First, connect the end with the 35mm diameter to the machine. Just push it in and use the small square push - to - release button if you need to remove it later. Then, attach the bent end piece with a 31mm diameter to your standard 32mm pipe. Make sure it's firmly connected. When using the vacuum, avoid sharp bends in the hose as it might affect the suction power. For maintenance, after each use, check the hose for any blockages. You can use a long, thin object to gently push out any debris. Also, keep the hose away from heat sources to prevent damage. If you notice any cracks or significant wear, it's time to consider a replacement.
