INSPECT JAM PROTECTION FUNCTION

NOTICE:
Be careful not to be caught any part of your body when
checking.
HINT:
When performing resetting of the limit switch, do checking after
repeating up and down of the glass with automatic operation.
(a)

Confirmation of AUTO up operation:
Confirm that the window will be fully closed with AUTO up
operation.

(b)

Checking operation of the jam protection function:
(1)

Move up the window with AUTO up operation and
check that the window will go down when it touches
the inserted handle of the hammer.

(2)

Confirm that the window will then stop going down
about 200 mm (7.87 in.).

HINT:
When removing the glass, glass guide, regulator, etc. be sure
to perform checking of the jam protection function.
If the jam protection is not functioning properly, adjust the power
window motor limit switch and pulse switch.
