WINDSHIELD WIPER SYSTEM
8-79
If the blades do not park in the desired
Y2 cycle
but require 1% cycles to park, the procedure of going
through the switching operation must be repeated as
follows:
(a) Turn the switch to the "ON" position and al-
low the wiper system to operate for a few cycles.
(b) Turn the switch to the "OFF" position, only
this time allow the timing of operating the switch to
occur at a position in respect to wiper blade travel
that is slightly later than the first operation. Again,
note the cycle requirement to reach park.
Having parked the wiper system in Y2 cycle of mo-
tor operation note whether the wiper blades have
traveled well below the normal wipe pattern. If they
have not, replacement of the parking cam, spring and
spring trip is indicated. If they have, but have not met
the requirements for proper park position, a wiper
arm adjustment is required.
Parking Spring Lubrication-
Variable Speed
To insure satisfactory life of the parking mecha-
nism use only Led-Plate, Part
No.
2275437 to lubri-
cate the parking spring during service. It is essential
to thoroughly coat all rubbing surfaces of the spring
and pin area. Use of any other lubricant than Led-
Plate (such as lubriplate, etc.) will result in noisy op-
eration, rapid wear of components and premature
failure of the parking mechanism.
