The equipment
consists
of two
jets
mounted
on
the scuttle
just
forward
oi the
windscreen
wiper
blades.
A
press button
is situated
within easy
reach on the
right-hand
side
of the
facia,
and
on depressing
this button
the
induction depression
is communicated
to the
diaphragm
of
a
pump on the
reservoir,-which
is a
glass
container
underneath
the
bonn-et.
When
the
button
is released,
the diaphragm
is
returned
under
spring
pressure
and causes two
jets
of
fluid to
be directed
on
to the
windsCreen.
The
screen
wipers
should
then
be switched
on,
when the
screen
will
immediatelv
be cleaned.
The
liquid
in
the
reservoir
has
low surface
tension
and
anti-
freeze
properties.
As
the
pump is actuated
by
the
induction
pipe
depression,
it
is necessary
to ease
the
foot off
the
accelerator
pedal
whilst
the
button is
being depressed,
other-
wise there
may
be insufficient
depression
to
actuate
the
pump.
The
jets
may
readily
be
cleared
if thev ever
become
obstructed
with
foreign
matter,
by slackening
off the
knurled
screw
and operating
the
pumP
in the normal
w&y,
as the
jet
consists
of a
small slot
which
becomes exposed
when
the screw
is slackened
off,
and
any ob-
struction
is therefore
easilv
washed
away.
Adjustment
of the
angle
of
the
jet
is effected
by turning
the
hexagon
portion of the
jet
with
a suitable
spanner.
The
j.t
should
impinge
on
the
wind-
screen
towards
the top of
the
arc
traversed
by the screen
wiper
blades.
Do'not
attempt to dismantle
the
part
of the
jet
attached to
the scuttle,
as
reassembly may
be diffrcult.
Tins
of this special
liquid, which
is
the
reservoir,
are obtainable
from the
Road, Willesden,
N.W.ro, and
