The windshield washer in Mazda 6, the first generation, is quite fragile and easily broken by adjustment. Each nozzle is divided into two parts, each with two nozziples. The centre of every half of the nozzle has a projection.
In order to minimize the risk of breakage, you need to use thin passages: the nozzle must be seized by the passengers on the central lug and should be adjusted. If there are no passages, you can try to adjust the nozzle by your fingertips, but you will have to make a great effort.
The regulation of the Mazda 6-needle marks is not recommended because it is more likely to lead to breakage.
