Lifting
the cor with o
Power iock -
When
r-rsing o service
Power iock, let the
cor rest on
the points
shown in Fi1.1.412.
To tow the cor, hook the towing rope on
to
the brocket under
the cor nose. Threod the pin
through the loop of the rope
ond the brocket
lugs ond secure the pin
with o cotter pin (both
thL pin
ond the cotter pin
ore included in the
cor occessories).
1.5 SPARE WHEEL
AND FUEL TANK
Spore wheel -
After having opened the
lug-
goge boot lid, pull the hondle of the spore
wheel corrier releose
rod.
The corrier is
re-
leosed ond swings
down (speciol equipment of
the cor includes
o sofety lotch behind the
bumper which hos to be pushecl
oside to
releose the corrier
) . After
hoving closed the corrier (by
lifting it),
push the releose lever under
the bumper to the
right os for os it will go.
Fuel tonk -
The filler neck with cop is in the
reor on the right-hond
side of the cor- lt con
be locked ond unlocked by meons of
the re'
spective key.
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
4.
Prepore the engine
to its temperoture:
- Storting from cold in
the occelerotor pedol
- Storting from cold in
the occelerotor pedol
choke for
storting occording
winter -
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.

Ihe permissible
out-of-bolonce must not ex-
ceed 50 grommes
on the rim rodius. Every new
tyre is provided
with o coloured dot on its side,
indicoting its lightest point.
Fit the tyre olwoys
with this dot focing
the tube volve.
ln this
position, the volve octs os on odditionol weight
compensoting the wheel overoll unbolonce to
o consideroble extent.
lf dynomic boloncing of the wheel is not
possible, bolonce the wheel stoticolly with the
greotest possible qssuroc|.
Boloncing weights
of 30, 50, 75,
ond 100 grommes
ore ovoiloble.
10.4 TUBED TYRES
For mounting,
dismounting,
ond repoirs of
conventionol tyres with inner tubes (for
por-
ticulors, see the preceding
Chopters), the usuol
procedures ore opplicoble. The permissible run-
out (untrue
running)
of the rim is the some os
for tubeless tyres (Chopter
10.5).
10.5 TUBELESS TYRES
The oir-tight seoling of these tyres requires
more core ond o different hondling thon thot of
the tyres with inner
tubes.
Preporotlon of Rirrr
13elore mounting the tyre, inspect the rim for
ony technicol defects. The points
to be checked
ore the rim shoulder ond the moting foce for
the tyre beods,
in oddition to the overoll con-
dition of the rim. lf ony defects ore found, the
rim must be reconditioned.
A sotisfoctory rim
nrust comply with the following conditions:
o) The
rim shoulder ond the tyre volve hole
must not be distorted;
there must be no
shcrp edges or protrusions
likely to domoge
the tyre beod. Minor unevennesses
con be
hornmered flot ond smoothed
with o file.
The moximum eccentric running
of the rim
side must not exceed 1.5 mm.
b) The moting surfoces
must be obsolutely
cleon (free
from stuck-on rubber, rust,
etc.).
Cleon them with emery poper
or o wire brush
ond coot them with point.
lnstolling of Tyre
Volve
Cleon the rim with o dry rog. Push
the rubber
volve into
the hole in the rim
or pull
it in
by
its threod using, for exomple,
o lever
os illus-
troted in Fig. 10.5/1. Fig. 10.5/1

Pulling Tyre Volve
irrto Wheel Rim
Mounting the Tyre
For mounting the tyre, use speciol mochines
ond procedures,
depending on the type of the
nrochine. lf such o mochine is not ovoiloble, in-
stoll the tyre using speciol tyre levers.
Ensure
thot the boloncing dot is next to the volve.
Tyre leverrs for fitting tubeless tyres
differ in
shope from conventionol levers. They
ore thin-
ner, without edges, ond polished.
Use them core-
fully in order not to domoge the
beod seoling
rubber bose. Insert the levers
under the beod
ot
short distonces ond refroin from using force. To
focilitote sliding of the tyre cosing beods over
the rim shoulder, moisten them with woter ond
top them with o rubber
mollet when eosing
them over the rim shoulder. Inflote
the mounted
tyre immediotely. Check the tyre for propei'
bedding in the rim ond
squore seoting
on it.
Holding the wheel perpendiculorly,
strike it
severol times ogoinst the f loor ot severol points
to force the tyre beods
to bed
correctly on the
bcad seots.
lnf lotion
Remove the volve
core to increose
the diom-
eter of the hole for oir inlet (oir
should be
iniected in quick
shots to force
the beods
on
to the beod seots) ond inflote the tyre. Use
o compressor with oir receiver, the
compressed-
.oir line of the
workshop, or
compressed-oirr
cylinders. The relief volves hove to be odiusted
to o pressure
of 350 kPo (3.5
kg/cmz).
Never ollow the inflotion pressure
to rise
unnecessorily. As soon os the tyre hos snopped
into position
on the rim
ond is free from leoks,
odiust the pressure
to 250 -
350 kPo (2.5 -
3.5
kg/cmz). lf the tyre refuses to
bed properly
on
the rim,
for exomple due to distorted beods or
beods compressed due to incorrect storoge,
press the tyre circumference inword to open
wide the beods which will then bed properly
on the rim. Use either o length of
rope or
o speciol tightener. Slip the rope over the
tyre
circumference with o certoin cleoronce, insert
o stick
between the tyre ond the rope, ond
twist the rope.
Adiust the tyre pressure
to specif
icotions ond
submerge the wheel in woter to check the
tyre
for oir leoks.

ond the slip-over ring in posltion.
Fit the

with the idler must
move freely olong the shoft.
2. Slip the respective
woshers on the shoft in

ormoture with the engoging lever
into the drive

Diognosing Storter Motor Defects in Cor
o) lf the storter motor refuses
to operote, look
first for on interrupted connection between
the bottery ond

motor, the engine
eorthing ond the storter
motor, or the engine
eorthing ond the bottery. lf these connec-
tions ore in order (current

b) lf the storter motor
continues running
even
ofter the ignition key hos been switched in
the switch box from the position "START",
it hos to be stopped without ony deloy by
disconnecting the bottery (using
its eorthed
pole).
c) lf the storter motor hos no power

Tentotive Checking of
Storter Motor

Connect the terminol "30'of
the storter
motor to o properly
chorged bottery ond incor'
porote on ommeter with o wide
meosuring ronge
into the circuit -
see Fig. 13.10/3.
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
springs. The
brushes must
beor on the commutotor by ot
leost two thirds of their surfoce ond they must
move freely in their cells.
The ormoture should hove o noticeoble oxiol
cleoronce (ploy)
not exceeding 0.7 mm.
At
o slight rototion of the pinion
in the direction
of the storter motor rototion,
the idlor must
slip
freely.
