bent. This can impair the correct functioning of the wiper. If
the wiper must be replaced, always remove the wiper arm
as follows.
1. If necessary, remove the covering cap of the drinking
valve and then remove it from the cap together with the
frame.
2. Loosen the screws (see figure F-1 on the fold-out page)
and remove the wiper handle (see figure E-6 on the fold-
out page).

the front port by pulling it upwards over the drinking valve.
The drinking valve remains in the front port.
