	Funding: This work is supported by Strategic Priority Research Program of CAS (XDA0302)and National Natural Science Foundation of China (91026004) Within the framework of the C-ADS project, IMP has proposed a 162.5MHz HWR Superconducting cavity for low energy section(β=0.09) of high power proton linear accelerators. A compact slow tuner has been developed for final tuning of the resonance frequency of the cavity after cooling down to operating temperature and to compensate microphonics and Lorentz force detuning. The slow tuner is driven by an external stepper motor and gear box for coarse cavity adjustment. To reduce the force requirements of the actuator, a lever arm and scissor jack mechanism have been applied. The tuner design and recent results of warm tests as the first prototype are presented.
