How to change the seals on your STERWINS high pressure cleaner

It is important to check the condition of the seals on your STERWINS high pressure cleaner regularly.
When damaged, the seals can cause a sealing problem, often accompanied by a drop in pressure. At the first sign of wear (whitening, cracks), replace them easily using a lubricant of your choice.
That's why we've shown you how to change them on our ST1, ST3, ST5 and ST7 high-pressure cleaners.
