Risk of damage to the suspension struts due to insufficient lubrication.
It is difficult to inject the oil. Even so, do not fill oil through the sight glass
connections. If you do this, the oil will not reach all the lubricating points.
•
Check whether oil is visible in the centre of the sight glass (1) on each
suspension strut.
If the oil level is too low
•
Open the connection (2) – oil escapes – and quickly connect the press with
the hose.
•
Inject oil until it reaches the middle of the sight glass.
•
Remove the hose and quickly close the connection (2).
