Alpine I
To obtain the best operating sweep, the recom­
mended procedure is to fit the wiper arm to the
serrated spindle so that, with the glass wet, the
full extent of the sweep away from the parked
position brings the wiper arms to an angle of 41
degs. from the vertical; In this position the tip
of the wiper blade on the driver's side will be
approximately 3 inches (75 mm) from the outside
edge of the glass. It should be observed that
when the wiper blades are in the parked position
they are a littlf away from, and at a slight angle to,
the base of the screen.

onwards
A larger wheel-box fitted to wiper motors on the
driver's side of the car has resulted In an increased
arc of wipe on that side to 122 degs., and I 03 degs.
on the passengers side.
This Improvement has been introduced from
Chassis Number 8.9104616 R.H.D. B.9104783
L.H.D. (U.S.A. and Canada only) and 8.9108012

_.
H.D. (Remaining countries taking L.H.D. cars).
To ensure the correct position of wiper arms on
this model, proceed as follows:-
Remove both wiper arms and blade assemblies.
Switch ON the ignition and with the screen wet
operate the windscreen wiper switch ON and
OFF to position the serrated spindles in the parked
condition.
Flt the wiper arms, complete with blades, on to
the serrated spindles with the lower edge of the
wiper blade positioned approximately ¼ inch
(6 mm) away from the base of the screen.
Any attempt to obtain a parked position with the
wiper blades against the screen moulding will
result in noisy operation and a reduced arc of wipe.
Slight adjustments to the parked position of the
wiper blades may be carried out as described
above.

Combined Windscreen Wiper Switch and
Washer Control (Later Models)
Integral with the switch on later models Is a
windscreen washer pump unit, the control knob
for the windscreen wipers also actuating, when
depressed, the bellows of the pump unit.
The switch unit and bellows unit are separable
from each other, so that where one unit becomes
defective In service it can be dismounted from its
mating unit and a new unit installed. All that is
necessary to detach the bellows unit from the
switch, Is to unscrew the unit leaving the switch
In position. Before detaching Lucar connectors ·
from the rear of the switch, always disconnect the
positive (earth) terminal from the battery. The
complete assemble Is retained to the facia panel by
a chromium plated ring-nut which Is situated at
the front of the facla Immediately In front of the
facia control knob; to detach the control knob,
first depress the spring-loaded catch which ex­
tends from the control shaft Into the shank of
the knob.
Do not attempt further disassembly as no pro­
vision Is made for the repair of defective units.
