FORD 2002 F-550 v.2 - Manual (Page 66)

WINDSHIELD WIPER/WASHER CONTROLS
Rotate the windshield wiper control
to the desired interval, low or high
speed position.
The bars of varying length are for
intermittent wipers. When in this
position rotate the control upward
for fast intervals and downward for
slow intervals.
Push (tap) the end of the stalk
briefly for a single swipe (no wash).
Push and hold the end of the stalk
to activate washer. The wash cycle
will continue for up to ten seconds
or until released. After release,
there will be three clearing wipes.
Windshield wiper blades
Check the wiper blades for wear at least twice a year or when they seem
less effective. Substances such as tree sap and some hot wax treatments
used by commercial car washes reduce the effectiveness of wiper blades.
Checking the wiper blades
If the wiper blades do not wipe properly, clean both the windshield and
wiper blades using undiluted windshield wiper solution or a mild
detergent. Rinse thoroughly with clean water. To avoid damaging the
blades, do not use fuel, kerosene, paint thinner or other solvents.
