[faq]

What is the Dirtkiller 70 repair kit used for?|To regenerate the Dirtkiller 70 turbo nozzle (rotary nozzle) and restore correct operation of the working subassembly.

Does the repair kit replace the complete rotary nozzle?|No. It is a set of service parts for repairing the subassembly, not a complete turbo nozzle.

How do I confirm the kit is compatible with my accessory?|Most reliably by checking the Dirtkiller 70 designation, MPN 410979, and compliance with the manufacturer’s technical documentation.

When is regeneration better than replacing the entire nozzle?|When the body and main structural elements are in good condition, and wear concerns consumable parts intended for replacement.

What should be done after completing the service?|After installation, perform a leak test and a working-pressure test to confirm correct assembly and stable nozzle operation.
