a) FDX view –level cap and seal–
How to change the FDX oil:
To replace the oil is recommended to disassemble the unit from the car. Open the cap bellow, drain it and
close it again. Measure the quantity and put in the same quantity. If you are doing it mounted on the car,
take care, 100 ml will not be possible to add from the cap (shown in the picture b) above). The last 100 ml
have to be added through the venting pipe on top.
Note:

In case of disassembling the unit from the car, the unit must be positioned in vertical position, as
it is shown in the picture a), to avoid any oil leakage.
