The switch box is completed with a
removable switch key. Confusion of
switch keys is not possible. First turn the
key in the RUN position. A red signal
lamp indicates that the electric circuit on
the chipper is on and properly
interconnected with the tractor wiring.
For proper functionality of the loading
rolls it is necessary to turn the key in the
START position and finally to release the
key. A yellow signal lamp lights up that
means the machine safety circuit is
activated. After any interruption of the
safety circuit, or for repeated starting, this
circuit must be activated again.
The safety frame for material loading
serves as an actuator for the loading
rolls control, i.e. for their stopping to
protect attending persons against their
getting caught by loaded materials.
The additionally installed buttons can
control reversing and putting the rolls
in motion repeatedly.
