The thermometer indicotes the temperoture
of the coolont with the ignition switched on.
The optimum operoting temperoture ronge is
from 75 to 105oC. In
SfOon 105 S, this
ronge
is identified by
the green
zone of the scole.
The fuel gouge
indicotes the level
of the fuel
with the ignition switched on. The scole is
provided with divisions 0 -

The driver is worned by the red worning light
when thene ore less thon 5litres of fuel in the
fuel tonk.
The tochometer indicotes the speed (revol-
utions) of the engine. The
speed should
never
rise to the red zone. When chonging the geors,
on increose of speed within the ronge
of the
yellow zone is permissible.
The porking
lights come on when the switch
is thrown to the first
right-hond position.

1.6 STARTING THE
ENGINE AND CHECKING
ITS CORRECT RUNNING
1. Moke sure thot the geor
lever is in its
neutrol position,
switch on the ignition (pos-
ition I on the switch box) ond wotch the
coming on of the oil pressure ond chorging
worning lights, i.
e. check the function of the
olternotor -
see the informotion in porogroph

Prepore the engine
to its temperoture:
- Storting from cold in
the occelerotor pedol
- Storting from cold in

do not touch
ond use the full choke
summer -
do not touch
ond use only holf of the
Fig. 1.5/1 Hondle ot
Rod (f ronr obove )Spcre
Wheel Lock
crnrl Safety Lotch -
Storting o wormed-up engine -
depress the
occelerotor pedol
slowly to tlre
toe-boord, do
not touch the choke
2. Depress the clutch pedol
(odvisoble
in
summer, necessory in
winter) ond stort
the
engine by turning the ignition key to position
ll.
Let go
of the key os soon os the engine fires
ond releose the occelerotor pedol
{if it hos
been
clepressed).
It the engine ,refuses
to fire, return the key
to the position "0"
ond rePeot the
storting
Pro-
cedure. lf the engine is wormed up, depress the
occelerotor pedol
to obout one third of its totol
trovel. lf the cold engine stolls even
ofter the
second ond third storting ottemPt, enrich the
storting mixture by quickly
depressing the
oc-
celerotor pedol
once or twice to holf of its
trovel during the next storting ottemPt.
Never let tlre storter motor run for more
thon
obout 5 seconds. Woit
some 5 seconds before
repeoting the storting.
Fuel is injected
by every quick
depression of
the occelerotor pedol
ond enriches the mixture
so thot it is difficult to ignite. lf the engine
is flooded, stort
it
with o fully depressed oc-
celerotor pedol.
3. Increose the engine speed corefully while
releosing the clutch pedol. lf the
engine shows
signs of stolling, depress
ogoin the clutch
pedol.

Dissssembly
ond
Reossembly of Pedols
This is usuolly not necessory. The pedols
con
be disossembled ofter removing the oxiol screw
in the pedol
pin
ond slipping off the return
spring. Do not remove the switches if it is not
obsolutely necessory -
see odiustment. On re-
ossembly, lubricote
the pedol
bush with lubri-
coting greose
of the some brond os used for the
steering linkoge -
see Chopter 7.5, por.3.
Pedol Free Trovel
Adiustment
Adjust the free
trovel of pedols
ossembled
with moster cylinders so thot the pedol piston
rod hos o
cleoronce of 0.5
to 1mm
when beoring
ogoinst the piston
heods of the
moster cylin-
ders. The free trovel of the pedol pod
should be
from 3 to 5 mm. lt
con be odiusted by rototing
the eccentric pin
on the pedol
brocket -
see
Fi9.12.111.
For the odjustment of the broke pedol
with
broke booster ond/or levelling of the broke
pedol with the
clutch pedol,
see Chopter 9.6 -
Ad justment.
Adiustment of Switches The switches con be
moved in
the ellipticol
holes of the brocket ofter loosening the fosten-
ing copscrews with ploin
woshers under their
heods. A pocking piece
should be slipped
under
the switch of the broke pedol
trovel worning
light ond the powl
of the switch pin
should be
held down under the fostening copscrew.
Ad just
the stop-light switch
so thot it
switches on the stop lights ot o pedol
trovel
of 10 to 15 mm meosured on the centre of the
pedol pod.
Adiust the pedol
trovel signolling switch so
thot the pushed-in
side push-button
pin
is
re,ecsed ot o pedol
trovel of 100 to 110 mm
mecsured on
the centre of the pedol
pod.
Press
the push
button into
the switch ofter hoving
completed the
odiustment.
12.2 ACCELERATOR PEDAL AND CABLE
The occelerotor pedol
forms o unit with its
self-lubricoting beoring ond the lever.
lt is
bolted to the f
loor tunnel. A coble possing
through the tunnel is ottoched to the pedol
lever ond the reloy
lever on the engine by
meons of clomps- The coble is protected
by
o Bowden tubing.
Pedol Removing ond Refitting
1. Loosen the clomp holding the coble on the
engine-mounted reloy lever. 2.
Remove the copscrews holding
down the
becrring with the pedol,
depress lightly the
pedol, ond lift it out of the f loor
tunnel together
with the beoring. 3. Disconnect the pedol
from the coble ofter
ioosening the clomp.
Removol ond Refitting of Bowden Tubing
ond Cqble
The Bowden tubing is
fostened to
the brocket
irr the floor tunnel by
meons of circlips. After
their removol, pull
the Bowden tubing inside
the cor. On ref
itting the tubing, lubricote it with
o low-viscosity oil (of
the SAE 20
closs). lt hos
been lubricoted with greose
in the foctory.
Fit
the clonrps so thot their longer ports (from
the
screw to their end) ore on the side of the
I evers.
Accelerotor Coble Adiustment
Adjust the coble so
thot it is not
excessively
tensioned or too slock. Loosen the clomps on
the engine side of the coble, move slightly
the
clomp toword the reloy lever,
ond tighten the
screws of the clomp.
12.3 GEAR SHIFT LEVER
AND LINKAGE
The geor shift mechonism consists of two
units: the geor
lever with its housing ond oc-
cessories, ond the geor
shifter rod
ond the
shifter lirrk with joint
(ot the georbox)
for
domping the vibrotion of the power
pock
tronsnritted to the geor
lever.
Removing Geor Lever
Housing ond Link
1. Lift owoy the mot from the floor tunnel in
the front ond reor comportment. lf seporote,
remove the individuol floor mots ofter hoving
prised out their clips with o screwdriver or
o similor tool. lf o one-piece floor
covering is
used, remove the door sill strips
on one side,
tip the seot, ond bend over the
floor covering.
2. Remove the geor
lever housing copscrews
ond prise
out the lid (next
to the clip) between
the seots. Proceed through the
operture to dls-
connect the bolted connection of the link with
the housing shifter rod.
3. Lift
owoy the housing with the lever
through the operture. Swivel the lever so thot
the shifter rod
does not protrude
over the
housing beoring thus obstructiong the removol.
4. Usuolly it is not necessory to remove the
geor shift link from
the cor. lf
obsolutely necess-
ory, the link con be
disconnected only ofter

ond the slip-over ring in posltion.
Fit the
circlip
into the groove
in the shoft, ond drive the slip-
on ring over it. The pinion
with the idler must
move freely olong the shoft.
2. Slip the respective
woshers on the shoft in
their originol sequence (corrier
ring, distonce
ring, fibre ring, distonce ring) ond insert the
ormoture with the engoging lever
into the drive
end shield. 3. Suspend the switch
ormoture into the
pre-engoging lever ond bolt down the switch
lightly. Fit the lever pin
into the drive
end
shield ond lock it in position
with the retoiner.
4. Tighten the copscrews of the switch
ond
fit the stotor on the drive
end shield.
5. Instoll the respective
woshers into
the
commutotor end shield in
their originol se-
quence (the dished wosher with its centre
focing the shield, then the ploin
wosher, the
toothed wosher, ond the drive wosher).
6. Fit the commutotor end shield with lifted
brushes on the shoft (in
the position
occording
to the recess
for the excitotion outlet ond the
notch) ond screw in the clomping bolts.
7. Instoll the brush interconnecting strip ond
bolt it down together with the field winding
outlets to the positive
brush holders, lower the
brushes. 8. Fit the Insuloting strip in position
ond bolt
down the cover. 9. Test the storter mottr.
Diognosing Storter Motor Defects in Cor
o) lf the storter motor refuses
to operote, look

Stort the
engine (feed
current to the terminol "50").
The
volue of the current ot idling speed must
not
exceed 65 omperes (not
considering the peok
ot
the first momentous deflection).
The storter motor must run noiselessly,
smoothly, ond the pinion
must move smoothly
into ond out of the rest position
(engoge
ond
diesengoge). The engoged pinion
must not ro-
tote direct on the foce of the slip-on ring. The
run-out of the storter motor must not lost longer
thon 8 seconds ofter the disconnection of the
switch from the current supply.
Inspect the brush pressure

leost two thirds of their surfoce ond they must
move freely in their cells.
The ormoture should hove o noticeoble oxiol
