TECHNICAL DESCRIPTION OF ASSEMBLY GROUPS.
Engines made by JIKOV are vertical 2-stroke ignition one-cylinder engines with atmospheric filling and forced air
cooling. Crankcase, cylinder, flange and case cap are aluminium castings worked on functional surfaces. Crank shaft is
mounted in two antifriction bearings. Rotor of cooling system fan and cup of engine manual starter are mounted on the
upper end of the shaft. Air cleaner has a high-quality cleaning insert and oil filling in the cleaner body enables operation
even in a very dusty environment. Carburetter with control in on the left side of the engine. It is equipped with a fuel
cock and starting air throttle for easier starting of the cold engine. DV engines are equipped with a decompression
valve for easier start of the engine.
Ignition is located on the front engine face. Dynamo-magneto is on the rotor of ventilator which is under the plastic
tank.
Plastic fuel tank is located above the engine. Fuel system is equipped with a fuel cleaner.
Engine is started by manual starter which is mounted so that the driver can start the engine from the machine operator’s
site. It consists of a cup with incisions, disk with pawls, winding cord and handle.
Exhaust silencer is on the right side and it is provided with a casing to prevent burning of the operator when handling
the engine.
Engine rotations are controlled by an automatic speed-limit device. A lever which falls into incisions in the tank holder
is to control engine rotations in three stages of regulation.
On the lower part of the engine an aluminium flange is screwed on inside which there is a twin-jaw centrifugal clutch
whose design makes it possible to adjust a correct function of clutch switching in dependence on engine rotations by
means of adjustment bolts. Clips of quick-operating clamps by means of which the engine unit is to be secured on the
gearbox are screwed onto the flange.
IV. INSTRUCTIONS FOR USE.
MACHINE ASSEMBLY
The drive unit consists of a complete engine assembly (with clutch, steering members and flange) and handlebars.
The complete engine assembly is first added a holder of handlebars, which is to be screwed onto bolts on the rear side
of the engine by using nuts M8 and washers. Recommended tightening moment is 15.7 Nm.
Carrier tube of handlebars is to be slid into the lower swivel joint on the holder of guide handrails and the handlebars
are to be secured with carriage bolt M10x100, flat and lock washers and tightening crank.
Accelerator lever is to be screwed onto the right handrail in front of the rubber grip with a bolt and nut which are parts
of the accelerator lever. Mount the lever so that it does not bump into the rubber grip but is rather easy to reach even at
the position of adjusted maximum rotations. Bowden of gas control should be led from above through the carrier tube of
handlebars. Gas litz wire is to be set by means of adjustment bolt on the bowden so that the carburetter control has only
a negligible backlash.

ASSEMBLING THE SAFETY IGNITION SWITCH BVA-96
Cable for the safety ignition switch BVA - 96 is a part of the complete engine assembly. Cable eye on the yellow cable
is to be fixed under the left upper nut with which the holder of handlebars is screwed onto the engine. Pass flexible
tubing 12x0.5x300 mm through both cables. Dismount the safety ignition switch BVA-96 from the handlebars. Draw
the two cables through the lower hole in the handlebars carrier tube side up to the tube end. The insulation sleeving
which protects the cables in their lower part should be slid into the carrier tube of handlebars ca. 10 cm deep. Then
mount a plastic plug with hole onto the cables and knock it with its notched end into the upper part of the carrier tube of
handlebars. Pass the insulation sleeving 12x0.5x300 through the two cables again. Tip the rail of handlebars down, pass
the cables through it and mount the connectors into pins on cables leading from the body of the safety switch. Slide the
flexible tubing which protects the cables ca. 10 cm into the tube of handlebars.
Cables must be reaching in the carrier tube of handlebars and rail to such a distance that they are not stressed at
any of the extreme positions of the handlebars.
Connector on the yellow cable is to be mounted into the yellow cable on the switch and connector on the red cable is to
pu mounted into a shorter cable leading from the middle of the BVA-96 safety switch body. Cover the red cable
coupling with insulation sleeving! Put the safety ignitiion switch into the tube of handlebar rai and secure it with bolt
M5x10 with washer.
Correct functioning of the switch can be achieved only with the “live“ contact of the two cables being prevented!
Prior to each machine use check also the function of the BVA-96 safety ignition switch!
Bowden of gas control should be fixed onto the handrail with the plastic tightening tape at the lower bending of handrail
tube.
ASSEMBLING THE SHOCK ABSORBER
The use of shock absorber Model TG-2 which considerably absorbs vibrations generated during the machine
operation and transmitted onto the handlebars is compulsory for working with cutting adapters.
Assembly of the shock absorber "TG-2" is to be made according to Figure 2. Shock absorber foot is to be screwed onto
the lower box-angle plate on the carrier tube of handlebars with two bolts M6x14 with lock washers. The shock
absorber TG-2 (Position 2) is to be screwed onto the engine flange plate (Position 1) with bolts M8x16.
By tightening the rubber silent blocks set the position of handlebars so that it is in the machine axis. the tightening
should be made so that the rubber silent blocks have only a light contact with the surface on the complete assembly of
handrail holder (Position 1). the silent blocks are to be secured by tightening the counternuts.
Page 8
ADJUSTING THE SHOCK ABSORBER TG-2
Basic setting of vibration dampers see the assembly of shock absorber onto handlebars. Correct functioning of the shock
absorber requires de-arrestment of the pin on the swivel holder of handlebars. Tip the arresting-pin-controlling lever
upwards and secure it with the retaining split pin (See Figure 2). The handlebars are in their movement to sides
restricted only by the vibration dampers.

ADJUSTING THE GUIDE HANDLEBARS
Design of handlebars enables their setting to sides and height. Side adjustment is possible by arrestment pivot in the
lower joint of handlebars (Figure 3). There are three holes in the plate, into which the pivot falls thus arresting the
position of guide handlebars. There positions are used in cases when it not desirable that the operator moves on the
worked soil (e.g. at rotary cultivation). Height adjustment can be made at two places on the guide handlebars. Basic
height setting is made by loosening the tightening crank in the lower joint, setting of the carrier tube of handlebars in
the teeth on the carrier tube and lower joint, and by a subsequent tightening of the bolt. Finer height setting of
handlebars height can be made by loosening the tightening crank in the upper joint, slight turning in the teeth on the
carrier tube and in the upper joint of the rail, and by a subsequent tightening of the tightening crank.

MOUNTING THE DRIVE UNIT ONTO GEARBOXES
Drive unit which is a power supply to prime all VARI-System machines is mounted into a flange in the upper part of
the gearboxes.
On the lower face of the complete flange assembly there is a cylindrical part which is to be slid into the gearbox flange
when mounting the drive unit onto the gearbox. A second part to seat the driving unit onto the gearboxes is a pivot on
the holder of handlebar rails, which is to fall into a hole in the console on the gearbox flange. The pivot is to be secured
by screwing in the crank which is a part of the gearbox.
In gearbox Model T - 20 A the drive unit can be installed in two directions, which makes it possible to properly use
engine’s power with respect to gearing of the gearbox.
Methods of drive unit installation for different works are described in the instruction manual for gearbox Model T - 20
A.
In gearbox Model T - 2 and pump Model DZP - 003 the drive unit position on the gearbox is to be secured not by means
of the pivot in the handlebar rail holder but by means of a pin which is pressed into the gearbox flange and which falls
into the hole in the complete flange assembly after the driving unit has been mounted onto the gearbox.
PROCEDURE OF DRIVE UNIT INSTALLATION
1. Get the gearbox with working implements or attachments you wish to use at work ready according to relevant
instructions in the operating manuals for the given machines or implements.
2. Clean the connecting points for the gearbox and the inside of the clutch disk.
Clutch disk in the gearbox must not be greasy since the centrifugal clutch might be slipping and the clutch lining
and engine crankshaft sealing could suffer damage due to higher temperature!
3. Release the tightening crank which retains the pivot (which is a part of the holder of guide handlebars) in the
gearbox.
4. Clean the surface of cylindrical flange and pivot on the holder of guide handlebars from dirt.
5. Hold the driving unit with one hand gripping on the holder located on the front face of the engine while holding it
with the other hand by the upper joint of handlebar rail.
Page 10
6. Put the drive unit on the gearbox so that the cylindrical part of engine flange falls into the gearbox flange and the
pivot on the holder of handlebar rails falls into the hole in the console on the gearbox.
7. Move the drive unit slightly to and fro until it fully sits on the gearbox.
8. Then secure the drive unit by means of two clips of quick-operating clamps. Pawls on the clips of quick-operating
clamps are to be hooked on pins in lugs on the gearbox flange. Lock the quick-operating clamps by pulling on the
eye of the clip towards the engine case surface.
9. Finally, tight the tightening crank which secures the pivot on the holder of guide handlebars in the gearbox.
Removal of the drive unit is made as a reverse procedure. Loosen the clips of quick-operating clamps by disengaging
the quick-operating clamp so that you take a hold of the clip eye from below and pull it upwards. Pawl of the clip is to
be taken out from the pin and the quick-operating clamp should be pushed aside so that it does not stand in the way to
the removal of the drive unit from the gearbox.
Be careful when engaging the quick-operating clamps. Your fingers might be injured. Clips have a high tension
and engagement of them requires force.
Be careful at removing the drive unit and its displacement onto another machine since the exhaust silencer is hot
while in operation.
During the removal or installation the machine should be approached from the left side, i.e. from the side of air
cleaner and carburetter on the drive unit engine.

ADJUSTMENT AND MAINTENANCE OF THE JIKOV ENGINE
1. PREPARATION
a) Fuel: Use only automobile petrols of which the best is currently available Czech petrol grade SPECIAL 91. Two-
stroke engine are lubricated with a fuel mixture consisting of petrol blended with oil at a recommended ratio.
For lubrication of this two-stroke engine the manufacturer recommends a mixture of petrol and oil. Use oil "MOGUL
TS " or “MOGUL TSF” designed for heavy-duty engines, with excellent lubricating properties, at the use of which a
well-set engine exhibits lower values of emissions and smoke density. Blending ratio of the mixture (petrol : oil) is 50 :
1. For the time of running in the engine (ca. 10 hours) it is advisable to reduce the ratio to 33 : 1 .
The mentioned oils are currently available in the network of petrol stations.
Adhere to safety regulations when refuelling. Do not refuel the machine in enclosed spaces, do not smoke and do
not do refuelling in a vicinity of open fire.
Fuel tank should be filled only up to 2.5 cm below the upper edge of the tank neck. Fuel tank volume is 3 litres.
b) Air cleaner: For the correct functioning of the oil air cleaner the body of the air cleaner must be filled with engine
oil. Remove the lower part of oil air cleaner by releasing the tightening sleeve and fill it with engine oil which is
normally used for petrol/oil mixture.
Oil surface is to be max. 0.5 cm above the bottom of the lower part of the oil air cleaner.
It is advisable to make regular checks of oil for its contamination in the lower part of the cleaner. If so, replace it with
new oil without delay.
In the dry season (summer months and at cutting), check the air cleaner every day, otherwise once a week. Practical
results from the machine use indicate that oil must be exchanged after about 30 hours of operation.
Air cleaner should be checked with the engine switched off !
Air cleaner insert wash out in technical petrol –when dirty- and before mounting it back, let it dry properly. The check
is to be made along with the check of oil volume in the oil air cleaner.
2. STARTING THE ENGINE
Start the engine only when it is coupled to a gearbox or another aggregate of the VARI-System!
Do not start the engine in enclosed rooms. Gases generated at fuel combustion are dangerous to life!
When starting the engine, shift the gear to neutral or disengage the travel clutch. Be very careful in aggregates
without a possibility of disconnecting the drive from the machine since the machine may get into motion at
increased starting rotations.
Start is to be made so that you will stand behind the machine in the direction of the starting cord, holding the
handlebars and controlling the accelerator lever with your left hand and making start with your right hand by using
the grip on the starter cord. Engine rotations should be reduced immediately after the start. Safety ignition switch
is in Position 1 at starting.
a) Cold motor:
Open the fuel cock, shut the starting throttle (lever must point upwards) and set the accelerator lever to about a 1/3 of
lever step. Put the starter gearing into engagement by slightly pulling the handle out and start the engine by a rapid pull
on the handle of the self-returning starter. Right after start, open the starting throttle (lever in horizontal position), but
do not load the engine with high rotations.
If the engine does not start at a second try, the starting throttle must be opened, accelerator lever set to full opening and
the start should be repeated.
b) Warmed-up engine:
Open the fuel cock. Set the accelerator lever to about a 1/2 of lever step and start the engine.
It is recommended that the fuel cock on the carburetter is closed even at a shorter break in machine operation.
3. OPERATION
After having been started, the engine can be fully loaded after about a minute. Speed limit governor on the rear face of
the tank serves to set engine rotations according to the used machines or implements or works to be carried out (see
instructions for use of respective implements and machines of the VARI-System).
4. STOPPING THE ENGINE
If you wish to stop the machine, shift the accelerator lever into Position "MIN", the centrifugal clutch will be
disconnected and the machine will come to a stop.
If you wish to switch off the engine, release the lever of safety ignition switch on the left handlebar and the engine will
switch off. This switch will provide for engine switch-off and machine stop in critical situations with danger of collision
or injury to operator.

5. TECHNIQUE OF CONTROLLING THE JIKOV ENGINE WITH AUTOMATIC CENTRIFUGAL
CLUTCH
Coupling of the centrifugal clutch depends on engine rotations. This is why steering of this type of engine requires
technique which differs from that applied in controlling for example an engine with multiple-disk clutch. Two working
positions of accelerator lever are illustrated in Figure 5:
– " MAX " : with accelerator lever in this position the engine has maximum output and the clutch is in full
engagement (provided that the engine is not overloaded and is not runnig at low rotations)
– " MIN " : with accelerator lever in this position the engine has no-load speed and the clutch is out of
engagement. Engine working speed is between 2500 to 4800 RPM. Use maximum engine rotations so that clutch
slippage and hence its damage cannot occur.
Engine rotations should be increased fast so that the engine has higher speed than the rotations at which the clutch gets
into engagement in order to prevent clutch slippage. Centrifugal clutch has a smooth engagement at a rapid increase of
engine rotations.

TECHNIQUE OF CONTROLLING THE SAFETY IGNITION SWITCH
Safety ignition switch Model BVA - 96 meets the standard of safety ignition switches used by manufacturers of small
gardening technology abroad. This switch ensures switching of engine ignition system and hence stoppage of engine
operation immediately after the operator has left its site in a critical situation or for putting the machine out of operation.
The safety ignition switch has three functional positions as follows:
Position 1 is to be used for starting the engine, setting engine speed or for a short-time putting of the machine out of
operation while the engine is still on.
At this position of the safety ignition switch, always shift on neutral gear on the gearbox or switch off the clutch of
travel wheels and disconnect the drive of working implements!
Position 2 is to be used for machine operation. If the machine is in operation, the wire dog has to be always released!
Position 3 is to be used for switching the engine off in critical situations or for putting the machine out of operation. The
engine will switch off after the lever of the safety ignition switch on the left handlebar rail has been released. Putting the
hand away from the handlebar will do to stop the engine on the condition that the wire pawl is released.

V. HANDLING AND MAINTENANCE
Regular treatment of the engine is very important for its long service life and correct functioning. If you adhere to these
fundamental maintenance instructions, the engine will serve you long without any greater problems.
It is advisable to have records on fuel mixture consumption and time of engine operation. The information is a good
indicator of the technical condition of the engine.
Thorough cleaning of the engine is recommended after 50 hours of operation. However, if your engine works in dusty
environment and under high temperatures (such as at rotary cultivation or cutting), the intervals of engine cleaning
should be shorter. Particularly important is to check the oil air cleaner (see page 26), vicinity of the upper part of
cooling fan rotor and fuel cleaner. Should these places be soiled or clogged, the engine output is reduced and the wear
of parts increased.
Take care that the stalks of plants do not get between fan blades and cylinder and head lamination when cutting highgrown swards. Insufficient engine cooling results in overheating and danger of engine seizure.
To clean the engine use only the “environment-friendly“ detergents !
Recommended Czech-made detergents are for example " ARVA - EKO " or " EKOLAN 93 ".
Clean the engine only when it is cold.
Proper engine operation needs correctly adjusted spark plugs. Spark plugs recommended for engines 1453 ISKRA,
1454 VAPE, and for engines 1447 VAPE DV CE, 1454 VAPE DV CE are BRISK N17 ( BRISK N17 C) and BRISK
D17YC respectively.
Spark plug should be cleaned with a wire brush after 50 hours of operation and the spark contact gap should be set to
0,6 - 0,7 mm by using feeler gauges.

DIAGNOSTICS OF DEFECTS AND REMEDIAL ACTIONS
Problem: Cold engine cannot be started:
Reason: a) Defect in fuel piping
b) Spark plug does not spark
c) Blocked main carburetter jet
Rectification:
ad a) Make sure whether there is enough petrol in the tank,
check whether the fuel cock is open and fuel flows through the feeding hose. If not so, clean the fuel system completely.

ad b) Screw out the spark plug, clean electrodes and insulator with a steel brush, set the gap between the
electrodes, check the ignition spark, fix the spark plug to the cable terminal and put the hexagonal block on the spark
plug to the exhaust. there must be a visible sparking to be seen on the spark plug electrode at a trial start.
If not so, use a new spark plug a test it according to the prescribed procedure. If the defect cannot be rectified even after
the spark plug has been exchanged, check the condition of the cable terminal and cable itself. Should the sparking not
occur even now, contact an authorized service shop for repair.
ad c) If the fuel gets into carburetter, the sparking occurs but the engine does not start, the reason may be a clogged
main jet. Dismount the float chamber, screw out the main jet and clean it by blowing it through.
Problem: Engine is warm but cannot be started
Reason: Engine is oversaturated with fuel mixture
Rectification: a) Turn the accelerator lever into Position "MAX"
b) Screw out the spark plug
c) 5times to 6times pull on the starter cord; this makes the engine turning while the excessive mixture
is blown out through the spark plug hole
d) Screw on the spark plug (cleaned) and start the engine
Problem: Engine warming up, not performing well
Reason: Clogged suction channel to carburetter and oil air cleaner, or dirty exhaust piping or clogged engine
cooling system
Rectification: a) Clean the oil air cleaner and piping
b) Clean the cooling system fan and lamination on the cylinder
c) Burn out the exhaust piping
d) Check the contents of tank and carburetter for possible water (water condensate may occur in drops
at the tank bottom or in the lower part of the carburetter).
VI. STORAGE
The machine should be kept at a dry place. Access of unauthorized persons to the machine should be prevented. The
drive unit must be installed onto one of adapters or secured so that its turning upside down and oil getting into the
exhaust or into the air filter and carburetter is prevented. At preparing the drive unit ready for storage, adhere to the
below instructions.
PROCEDURES TO BE CARRIED OUT PRIOR TO THE LONG-TERM STORAGE OF THE ENGINE
a) Wash the engine and clean it from all dirt and dust
b) Tighten all bolts on the flange and on the cylinder head
c) Check the function of spark plug and/or reset the distance of electrodes of the spark gap
d) Clean the carburetter and fuel piping, empty the fuel tank
e) Coat or spray the thoroughly cleaned engine and accessories with a preservative
f) During the long-term storage, put the engine into operation for about 30 minutes at least once in three months.
Before the start, remove all preservatives from the engine.
g) After the test, carry out operations described under items b), d), e).
h) Cover the engine with a suitable material (e.g. canvas or paper).
