Preventing damage to wiper arm bracket

NOTE
When angling the wiper arm (1) to the front, check that the wiper
blade is hanging free.
When angling the wiper arm (1) to the front, such as when wip-
ing the glass clean, if the wiper arm (1) is angled with the wiper
blade (2) locked to the arm (the bottom of the blade is caught on
2
the arm), abnormal force is brought to bear on the mounting
bracket and the bracket may break.
