Wind Deflector Inspection

INFOID:0000000001328047

1.

Make sure the wind deflector is properly raised by manual. If a
malfunction is detected, remove and visually check it. If it is
damaged, replace it with a new one. If no damage is found, rein-
stall it properly.

Link and Wire Assembly

INFOID:0000000001328048

NOTE:
Before replacing a suspect part, carefully ensure it is the source of noise being experienced.
1.

Check link to determine if coated film has peeled off to such an extent that substrate is visible. Check also
to determine if link is the source of noise. If it is, replace it.

2.

Visually check to determine if a sufficient amount of grease has been applied to wire or rail groove. If not,
add grease as required.

3.

Check wire for any damage or deterioration. If any damage is found, replace wire.
