About this manual

The Cangtai CTA40 is a water‑mediated self‑cooling hydraulic retarder designed for auxiliary braking on truck chassis. It uses water as the working medium to provide high‑power, long‑duration, wear‑free braking by converting vehicle kinetic energy into heat.

This service manual covers the retarder’s installation position, component assembly, internal structure and operating principle, as well as detailed instructions for the display screen, cabin panel switches, water and antifreeze filling, self‑check procedures, fault diagnostics, regular cleaning, and torque specifications for all fasteners. This manual is written in Chinese.
