Overview
Star arm replacement kit for the HydraMaster RX-20 rotary extractor, HydraMaster part number 078-067.
The star arms carry the vacuum heads around the rotary path. They take the impact when the tool meets a threshold, a tack strip or a piece of furniture, and they are a normal replacement item on a working machine rather than a fault.
Compatibility
Fits all RX-20 generations.
When to replace
Look for uneven wear across the vacuum heads, a change in the sound of the tool under load, or visible play at the arm. Replacing a bent arm early protects the head and the shoe, which cost more.
