13.18 FOG
LAMPS AND
OTHER OPTIONAL
EQUIPMENT
Fog lomps
The fog lomps ore optionol equipment. When
f itting them on the cor, refer to the wiring dio-
grom while observing notionol regulotions (in-
ternotionol regulotions
hove not yet
been uni-
fied os for os individuol requirements ore
con-
cerned) ond the following informotion. In
Czechoslovokio, the Decree
No.100/1975 of the
Book of Stotutes, porogroph
51, is opplicoble. Switching
reloy
Use o switching reloy of the some design
os
for the ouxiliory heodlomps (on
cors with twin
heodlomps) or onother reloy operoting in the
some woy. Any ploce
con be chosen for its
in-
corporotion into the circuit.
Cobles For worning lomps ond the reloy
switching
circuit use cobles with o section of 0.75 mm2,
for the remoining electricol equipment 1.5 mm2
section cobles.
R,ELAY SWITCHING OF HEADLAMPS
Optionol equipment moy include on incorpor-
crted reloy for switching in the heodlomps. In
some countries (for
exomple Sweden), this
reloy is required by regulotions. For the re-
spective connections see the following wiring
diogrom.

Prising off Door Ponel
When it is roining or when woshing the cor,
woter runs down the gloss
ond penetrotes
into the inner spoce of the door. The
foil is
supposed to prevent
the forming of under-
pressure in the cor interior ond to prevent
the woter from sooking the interior trims ond
running down into the cor. Therefore,
it hos
to be stuck on by rubber cement os shown
in Figs. 14.512 ond 14.5/3 (cross hotching).
First slip the lower port
of the insulotion
(foil), the inner end, inside the door, ond
then opply o seoling compound on to
the
door inner metol-sheet ponel
ond the insu-
lotion os indicoted in the illustrotion (block
dots ) .
Close both doors
on the side to be adjusted
and visually assess which areas of each door
require re-positioning to produce
an even
contour joining
the front and rear
wing body
lines in relation to the door
heights.
With careful adjustment of hinges, satisfactory
body lines
can be obtained.
Hinges can
be moved on the door pillar in
the
following ways.
1 . Up and down after slackening bolts.
Result:
height of door in relation to door ap_erture.
2. In and out after slackening bolts. Result:
Position of
the door leading edge in
relation to bodY aPerture'
3. Shims Pt.
No. 1 13-98B9OO between
hinges and pillar
a) Shims under
both hrnges moves
the door
rearwards and
increases the gap
between
the door leading
edge and the
wing
(Front door).
b) Shims under the bottom hinge
only, will
lift the lower edge
of the door.
c) Shims under the top
hinge only, will
have the reverse effect.
It is
sometimes preferable to remove
the door
catch (On pillar)
to remove misleading stresses
being placed
on the door. This part
being re-
fitted and adjusted so
that both stages of
the lock are
working and
ensuring door is not
being stressed by
excessive tension
up or
down, in or out.
Adjust the door
catch to ensure when
the door
is closed, it will
not ride up or down'
Ensure the door does not catch the door pillar,
wing, other door etc., when both are open or
closed.
Door top half
lf you-have correctly
adjusted the
bottom half
of thb door you
may find that the window frame
top half still needs an adjustment.
Here it will be necessary to
lower the moving
window and carefully bend the
frame of the
window to match the frame
of the door'

Repair of Window Regulator Defects
lf the windows are difficult to wind up and
down (the
maximum torque applied on the
spindle of the window regulator with the glass
installed in the doors exceeds 2.5 Nm) (1.77
tt
lbs), it is recommended that the following steps
are taken as regards both the front
and rear doors:
1. Disconnect the regulator driving plate
from
the window glass
channel. Push the glass
upward
and try the relieved regulator by turning the
regulator crank. lf the regulator does not work
smoothly (jamming,
rattling) or if
a torque higher
than O.7 Nm/(O.495 ft lbs) in front and 1.1
Nm/(0.78 ft lbs) in the rear is required for its
operation, replace the whole regulator with a new
one working satisfactorily.
2. Adjust the centre pillar position
in the door
using the jig
as per
drawing No. A1-1 5417-S.
Loosen the top screw of the centre pillar
and
retighten it while pressing
the centre pillar
against the window glass
wound up to its upper-
most position.
Loosen the bottom screw of the
centre pillar
and retighten it while pressing
the
centre pillar
against the
window glass. 5417

3. When bolting together the regulator driving
plate with the window glass
channel make sure
that the holes in these two parts
coincide along
the whole length of the channel. lf it is not so,
move the
channel into a satisfactory position.
4. lf the regulator is
not lubricated, lubricate the
regulator cable in the
tubing with grease
and
apply oil to the regulator
crank spindle.
To Remove ond Reinstoll Reor Door Fixed
Window
Agoin remove first the door trimming. The
gloss is only inserted
into the door frome ond
supported by o bolted-down holder with o rub-
ber pocking piece.
The gloss
con be moved in
the door
covity ond withdrown through the
door frome.
14.7 TRIMMING UPHOLSTERY AND WEATHERSTRIPS
Ponel-type Trimming
This type of trimming is used for
the doors -
see Chopter 14.5, Fig.14.511- ond for
the front
ond reor window posts.
Ponel-type trimming
fostened by clips (flexible
spocing pins)
covers
olso the porcel
troy below the reor window, the
outer guideroils
of the front seots, the front
wheel orches, ond the focia. On centre posts,
the trimming is fostened by screws.

After hoving wiped oll vornished ports
of the
bodywork dry, polish
them with o soft (flonnel)
duster. Do not use polish
of ony kind.
lf the bodywork is so dirty thot it connot be
woshed cleon with woter, use cor
shompoo.
lf it is necessory to refreshen the gloss
of the
finish, use o cor polish
occording to instructions
of its monufocturer. To wosh the underbody,
use o hose ond
running woter, worm or cold; never use petrol,
kerosene, diesel oil, etc.
Remove greose
spots with o cloth, dry or
sooked in petrol
if necessory. To
remove tor, dip
the cloth in kerosene or o speciol
tor removing
preporotion, ond rub the spots. Then
immediotely
wosh owoy oll troces of

o cor polish.
TOUCHING.UP VARNISH
Preporotion:
Removol of Polishes etc.
When touching up o repoired bodywork (dom-
oged surfoce
finish), it is
importont to olso
cleon the surrounding vornish
to prevent
the
touching-up point
from floking off loter on in
ploces of overlopping.
Remove cor polishes
with o shompoo. Silicone
oil, contoined in some bronds
of polishes
ond
preventing the odhesion of the touching-up
point, con be woshed owoy only with o speciol
preporotion. !n Czechoslovokio, this is
for
exomple VENEDIN. Rub with this preporotion
olso vornished oreos which will be roughened
by grinding
where the bore ploces
poss
into
ground ond cemented oreos.
Removol of Rust
Remove rust mechonicolly by grinding
or
rubbing with emery poper
ond woshing with
c derusting ogent (for
exomple SK 2,
which is
bosicolly o 300/s phosphoric
ocid).
Procedure: f irst cleon the rusty spot with
emery poper
No.80 ond 100
or using o grinder.
Then rub the spot with o 15 0/6
solution of
phosphoric ocid (SK 2 deruSter)
heoted up to
40oC. When using o cold solution,
its concen-
trotion must be obout 300/e (undiluted
SK 2
deruster). Work in rubber gloves.
After hoving removed the rust, wosh
the spot
twice. First
with tepid or cold woter,
soft or softened
by odding 2
to 2.501s of sodo,
then
with o solution of chromium trioxide (1 gr.
to
1 litre of soft
woter) heoted
up
to 80oC (thls
is
the so-colled possivoting
rinse). Now let the
spot dry.
Degreosing Degreose the spot to be touched up by rub-
bing it down with trichloroethylene or technicol
petrol.
1. Touching-up with low-boking points -
the most perfect procedure
o) Cleon the touched-up spot, derust
ond
degreose it (see
the previous
porogrophs
on
preporotion)
b) Sproy over with priming point
c) Let the priming point
dry ot 80oC to 110oC
for o period
of 50
or 15 minutes (50 minutes
ot 85oC, 15
minutes ot 110oC)
d) Coot over with synthetic cement or poly-
ester cement
e) Let the cement dry ot 85oC or 110oC for
o period
of 50 or 15 minutes respectively;
when using polyester
cement, the drying
period con be shortened -
this cement dries
of normol temperoture
f ) Grind under
woter with emery poper
No.280
to320till the spot is perfectly
flot ond even,
ond let it dry
g) Sproy with top-coot vornish
h) Let it dry ot 80oC to 110oC for
o period
of
15 or 50 minutes respectively; ofter boking,
the vornish hos
o high gloss
ond it is not
necessory to polish
it
i) Use o polish
to remove
ony visible troces of
tronsition between the originol ond the
new
vornish.
2. Touching-up with
nitro-combinotion vornish
o) Cleon, grind,
derust, ond degreose the spot
to be touched up
b) Apply priming
point with o brush or o
sproy-gun
c) Level up, if
necessory, with on oil-bose
cement (once
or twice)
d) Let
it dry lor 24 hours ond then grind
with
emery poper
No.220
e) Sproy
the entire touched-up oreo with
sproying cement ond let it dry for 24 hours
f) Grind with
emery poper
No. 280 ond 320
under woter till the oreo is perfectly
smooth
ond flot, ond let it dry
g) Sproy the touched-up spot with o vornish
prepored by mixing low-boking

oll, ploce
it into
the holcier so thot
there is
o suff icient distonce
(wide enough to
insert o

The cylinder heod
bolts should be tightened
in the running-in period before
the gosket gets
settled ond then
ofter every replocement of the
gosket, i.e., ofter
obout 1,000
kilometres' For

Alwoys turn the engine clockwise to eliminote ony ploy
in the distributor drive geor
ond to
ovoid loosening of the bolt. To relieve the
com-
pression resistonce, it
is recommended to bock
off the sporking plugs.
b) Stroboscopic method:
When using this method, the volues of the
bosic ignition timing ond
the odvonce con-
trolled by the centrifugol timing control (for
its
diogrom refer to Chopter 13.5) should be odded
upwhile multiplying bytwo
the odded upvolues
occording to the diogrom. Any effect of the
vocuum control must be
eliminoted by discorr-
necting the respective hose (connecting
the
distributor vocuum unit with the corburettor).
The meosuring procedure
is indicoted by the
diognostic equipment itself.
To Adiust ldling Speed
Use the oir-correction screw (speed
cor-
rection screw). The speed decreoses when ro-
toting the screw clockwise ond increoses when
rototing it onticlockwise.
Adiust the idling speed in occordonce with
the tochometer ond within the limits specified
in the following porogroph "To
Adiust ldle
Run". The engine must be wormed-up
before
storting the odjusting procedure (see
olso the
following porogrophs) ond its ignition must be
in perfect
condition (distributor
contoct-breoker
points, sporking plug
electrodes, ond ignition
odvonce).
