1. In troduction
-Takeover of the motorcycle
Control the outfit for completeness according to the documentation when taking
over the motorcycle.
-Control the serial number if
it coincides with the documentation-the serial num-
ber is located on the upper part of the frame and is readable from th e right side of the
motor. The motor number need not be identical with the number of the chassi
s. Get
acquainted with the main parts and control elements before your first drive (fig. 1).
-AT T E NT I 0 N -You have bought a two-stroke engine. It is therefore neces-
sary to mix the main fuel -gasoline with oil in the ratio 1:33 when breaking-in and
1:40 after breaking- in the engine. Use fuel with octane number 95 and oil SHELL-
SUPER
2T . When using synthetic oil SHELL SUPER 2TX the mixing ratio is 1:50.

4. Instructions for driving
Fill the tank with the gas-oil mixture befo re drivi ng as follows:
Unscrew the cap of the tank and release the air-release valve which is in the upper
rear part of the frame. Fill t
he tank up to the mark which is a wire sieve in the filler
neck. Close the air-release valve after refilling by tightening the screw and put on the
fi ll er cap.
AT TENT I 0 N I The air-release valve can not be loosened after fi lling the tank. it
could cause fuel leaking through the ventilation hole of the filler cap. If it is not possi-
ble to fill the ga s-oil mixture automatically at the petrol station mix the fuel in a vessel
before refilling the
ta nk.
Check th e following before dr iv in g:
-correct function of the brakes
- inflation pressure
- function of lights
- ti ghening of th e chain
Drive wi
th the heal ig ht on according to the traffic r eg ul ations.

Starti ng the moped
You can start the moped in two ways: a) on the stand
b) with moving vehicle by pedaling
a)
Starting with stationary vehicle is more common:
Turn the fuel cock
in the position ,OPEN" or ,RESERVE". Place the vehicle on the
central stand so that it stands on its front wheel (the rear wheel is in the air).
Approach t
he vehicle fr om the left side and put the pedal in such a position that it is
with the road at
an angle of 60o in the front posit ion. Press the lever of the starting
clutch 6 fig. 2 with the left hand and the choke 3 fig. 2 with the right hand. Put your
foot
on the pedal and pustll it quickly downward. Release the lever of the starting
clutch when the pedal is in the bottom position. The engine starts runni ng. Keep the
choke depressed for a short time which is necessary to warm up the engine.
Do not
use the choke with warm engine. If the start
is not successful repeat it.
A T T E NTI O N!
Do not use the choke to swich off the r un n ing engine.

b)
Starting by pedaling
Put the fuel cock into the position ,OPEN" or ,RESERVE". Use the pedals to start
moving. When you reach a sufficient speed press the clutch lever with t
he left hand
and the choke wi
th the thumb of your right hand at the same time. Release both lev-
ers after the engine starts. Turn the twist grip to continue driving. By full turning of the
twistgrip the throttle of the carburettor opens fully and the vehicle reaches its maxi-
mum speed.
Do not start with moving vehicle if the weather conditions are bad (wet road, ice
etc.).
Stopping the engine
Lower the rotations of the engine, apply brakes and stop the vehicle.
The engine is idling. Press the engine cut-off 8 fig. 2 (red push button on the right
side of the handlebar) and the engine stops.
Breaking-in a new engine
Prepare the fuel mixture by mixing gas and oil in the ratio 1 :40 . Drive the first 500
km with a maximal speed of 35 km/h.
5. Maintenance and adjustment
For cleaning the varnished and chromium plated vehicle parts use only water and
det e rg e nts. After washing , wipe these parts dry. Do not use kerosene and other sol-
vents when cleaning parts of plastics or rubber because they have detri men tal effect
on such parts.
12

Take a short ride after washing the vehicle and dry the brakes by repeated short
breaking.
Exhaust silencer - it
is almost not contaminated if you use the corrext gas-oil
mixture.
You do not have to clean it after the fi rst 5000 km. It is necessary to remove the
carbon deposi
ts if the gas-oil ratio was wrong and after several years of driving.
Adjustment of brakes
The front and rear brakes have two ad justment elements. Use the adjustment
elements at the end of the bowdens fig 4a, b for rough adjustment and the elements
on the control levers fig. 3a, b for fine adjustment. Set the adjusting screw 1 fig. 3a, b
on the handlebars into medium screwed position before rough adjustment.
Procedure: Put the brake lock into such a position that the jaws are fully open.
Loosen it slightly and fix it
in th is position by means of the adjustment element
(screw, nut). Press the brake lever.
13

If the play is too small: the lock of the brake has to be loosened more by means of
the adjustment screw on the handlebars.
If the play is too big: Find the right positi on by ,f ine" turning of the adjustment element
on the lever so that the knurled screw determines the right posi
tion and fix
it with the plastic nut.
The brakes are correctly adjusted when the levers have a play
of about 10 mm
from the grip after being depressed. The brakes must be adjusted again when this
distance decreases to about 2
mm due to the wear of the brake lining.

Tighte ning of chains of th efoot and eng i ne tra nsmi ss ion
Correct tightening of chains has an influence on the quality of driving and life of
parts. It should be therefore done with great care. Optimal tightening allows the chain
to sag about
10 mm under thumb pressur e. Both chains -the engine and foot chain -
must be
done at the same time.
15 -

Procedure :
Loosen the axle of t he rear
wheel and tighten the engine
chain and foot chain fig.
5b by
means of the tighteners 2. If the
tighteni
ng arm of the foot chain
pulley has a sufficient play of
about 15-30o , tighten the
rear.
wh ee l axle. If the tightening pul-
ley of the foot chain has a small
or
no possibilty of tightening,
loosen the nut of the pin
an d
tu rn the pin into such a position
wh ich makes t he movement of
the tightening pulley possible.

Adjustment of the carburettor
The B
IN G carburettor is adjusted by the manufacturer to give optimal parame-
ters. It
is therefore undesirable to change the setting because it could.influence its
optimal setting.
If the carburettor is out of order it is recommended to have it repaired in an au-
thorized repair shop.
Oil change in gear-box:
Recommended oil
is SHELL DONAX TA. Oil filling is done by producer for life
cycle of vehicle.
In case of any other repairs where oil must be changed, contact your
dealer.
Adjustment
of the ignition
Optimal ajdustment of t he ignition ensures optimal output of the engine. The ad-
justment has to be carri
ed out with utmost care and accuracy and should be done in
an authorized repair shop
18

Adjustment of the starting clutch
The starting clutch is adjusted by the manufacturer. After a certain ti me when the
friction material of the clutch wears out the clutch starts to slide and
it has to be read-
justed.
In order to readjust the clutch we must decrease the ,free movement" of the sta rt -
ing clutch lever. The free movevent should be 20
mm and we can set it by partially
unscrewing the screw of the clutch bowden 1 fig. 6 and its securing with the plastic
nut 2 fig. 6.
The second adjustment place is the bowden support in the lo wer part of the
frame (fig. 7).
