3. Operating Instructions
Power and Suction Control:
The CT 36 features intuitive push-button controls for easy operation. You can adjust the suction power across five levels to match the requirements of your specific task or tool. This variable speed control is available on all Festool dust extractors, allowing for optimized performance and reduced noise when full suction is not required.
Automatic Tool-Triggered Operation:
Designed for seamless integration with corded power tools, the dust extractor automatically starts when the connected tool is activated and stops shortly after the tool is turned off. This ensures continuous dust extraction during operation and clears the hose after use.
Bluetooth Connectivity:
The integrated Bluetooth module allows the dust extractor to start automatically when used with Festool Bluetooth battery packs or an optional remote control. This feature enhances convenience, especially for occasional cleanup tasks or when working with cordless tools.

4. Maintenance
Filter System:
The CT 36 comes standard with HEPA filtration and self-cleaning filter bags. The HEPA filter captures 99.97% of particles 0.3 microns in size, ensuring clean air. The self-cleaning mechanism helps maintain optimal suction performance by preventing filter clogging.
Filter Bag Replacement:
To replace the disposable filter bag, open the main compartment of the dust extractor. The bags are designed for easy and clean removal, minimizing exposure to collected dust. Replace the bag when it is full or when suction performance noticeably decreases.
