Strong musty or unpleasant odour from exhaust air during use.

Safety first: Unplug the machine and wear gloves when handling dirty water components.

• Clean recovery tank: Wash the tank with warm water and mild detergent. Rinse thoroughly and allow to dry.
• Flush hoses: Run warm water with a small amount of disinfectant through the suction hose and tools, then rinse.
• Replace filters: If the exhaust or motor protection filters smell or appear dirty, replace them with genuine Numatic filters.
• Dry thoroughly: Store the machine with tanks and lids removed to allow air circulation and prevent odour build-up.
