CAUTION

Make sure that the rotor yoke is firmly fastened to the drive shaft
with the rotor knob.

Since the rotor is not fastened onto the shaft when these parts are loose,excessive
vibrations will occur and damage the equipment and the rotor may fly off inflicting
physical injury.

mark of the rotor does not align with the drive pin,

the groove at the bottom surface of the rotor and drive pin do not fit.

In such a case, reinstall the rotor.

Do not start it in the condition
that the rotor knob got loose.

3. Fix the rotor yoke by rotor knob,

and then tighten by turning the
rotor knob clockwise.

4. After installation of the rotor, hold

the rotor yoke and attempt to move
