How to use

Detach the damaged hose from the vacuum body and accessories by releasing any locking collars or clips, then align the replacement hose ends with the vacuum inlet and accessory coupling. Push firmly until the hose seats on both ends and any locking mechanism engages. Test the connection by turning the vacuum on and checking for consistent airflow; if necessary, reseat the ends or secure the locking collars to eliminate air leaks.

Usage recommendations

Inspect hose connections periodically for wear or cracks and replace the hose if airflow decreases or visible damage appears. Avoid excessive bending near the ends and prevent sharp objects from contacting the hose surface. For best performance, use the hose with accessories and fittings compatible with Invest 400/321 style couplings and keep the hose clean from debris that may obstruct airflow.
