Using this vacuum motor is quite simple. First, make sure your vacuum cleaner is the Nilfisk Viking commercial model, some Numatic Henry models, or the Cleanfix S10. Then, use the included multifit mounting kit to install the motor in your vacuum. When using the vacuum, always plug it into a proper power source. Avoid using it on wet surfaces to prevent any electrical hazards. For maintenance, it's a good idea to clean the motor fan regularly. You can do this by gently removing any dust or debris with a soft brush. If you notice any strange noises or reduced performance, it might be time to check the motor and contact our support team if needed.
