If the textile covering of the FT3 is too tight or difficult to mount, it is often due to low temperatures. In this case, we recommend warming the covering slightly with a hairdryer before mounting. Hold the hairdryer about 20-30 cm away and warm the covering for 1-2 minutes until the material becomes more flexible. After warming, the covering can be easily mounted. Once the material cools down, it will contract back to its original shape.
