SEQUENCE OF WORKS
1. Use a needle or paper clip to turn the jets in the desired direction. To do this, carefully insert the tip of the needle into the jet hole and turn it to the desired position.

Fig. 3.23. When adjusted correctly, the water jet from the nozzle should be directed above the middle part of the glass
2. The jets should be installed so that the water jets are directed above the middle part of the glass (Fig. 3.23), then even at high speed (with the corresponding air flow pressure) the sprayed jet hits the entire washed surface of the glass. If the jets are directed too low, then in the frequent operation mode of the cleaner the liquid will not have time to wash the entire working surface of the glass.
