Optical Operating Fluid Detector for the Optical Detection of Operating Fluid for a Hand-Guided Garden, Forestry and/or Construction Machining Appliance, and Hand-Guided Garden, Forestry and/or Construction Machining Appliance

An optical operating fluid detector for optical detection of operating fluid for a hand-guided garden, forestry and/or construction machining appliance, the operating fluid detector comprising:

• a light source, the light source being designed for radiation of rays of light;
• an operating fluid line, the operating fluid line being designed for optical interaction of the rays of light from the light source with operating fluid in the operating fluid line for the optical detection of operating fluid;
• a light receiver, the light receiver being designed for differing reception of rays of light from the operating fluid line in dependence on a presence or absence of operating fluid in the operating fluid line,
• wherein at least one of:
• the operating fluid detector has at least one optical deflecting device, the at least one optical deflecting device being designed for deflection of the rays of light from the light source to the operating fluid line and/or for deflection of the rays of light from the operating fluid line to the light receiver, and
• the operating fluid line is designed for differing diversion of the rays of light from the light source in dependence on the presence or the absence of operating fluid in the operating fluid line for the optical detection of operating fluid.
