PROTECTION AND SAFETY ENGLISH

1. PROTECTION AND SAFETY OF HEALTH AT WORK

AJ 102 and AG 122 types of self-propelled mowing machines with the commercial name STARJET are manufactured in accordance with the effective Euro­pean safety standards.

1.1 SAFETY INSTRUCTIONS

Before the first use of your mowing machine, study this User‘s manual thoroughly. When operating the mowing machine follow the safety instructions stat­ed in this manual duly. In case the machine was used in conflictwith the instructions and information specified in this manual or legal regulations, the man­ufacturer bears no liability for the contingent damages and the user loses his right to the guaranteed repair.

Do not use the machine if any of its protective devices are damaged or missing.
All the covers and other protective devices must always bein place.
Therefore, do not remove or disablen any machine protective device.
Check the functions of these devices on a regular basis.
It is prohibited to performany technical modification on the machine without the manufacturer's approval in writing.
Unpermitted changes can lead to hazardous conditions of work safetyand thus to the cancellation of the guarantee.
Do not change the adjustment of the engine speed regulator or engine speed limit device.
Do not remove safety stickers or labels from the machine.
Before starting up the machine make sure you are thoroughly familiar with all of its control elements and their manipulation in such a way that you will be
able to stop the machine or turn the engine off immediately.
Always keep the machine and its equipment clean and in good technical condition.
The machine can only be driven by a person who is above 18 years of age and is acquainted with the instructions contained in this manual.
The machine must not be used for work on slopes with a gradient greater than 10° (17%).
The machine user is responsible for the safety of persons within the machine working area.
Do not move in the vicinity of the machine or under it if it is lifted and it is not properly secured against falling or turning over.
The machine user is responsible for the safety of persons within the machine working area.
Do not move in the vicinity of the machine or under it if it is lifted and it is not properly secured against falling or turning over.
Transport of other persons, animals or loads directly on the machine is prohibited.
The transport of loads is only allowed on a trailer whose type was approved by the machine manufacturer.
If you leave the machine unattended even for a short time, always removethe key from the ignition.
If you operate the machine outside the working area where the mowing is performed, always turn the mowing mechanism off and raise it to the transport
position.
If mowing is turned off, the mowing mechanism must always be in the transport position.

Always turn off the mowing mechanism as well as the engine and removethe key from the ignition if:

• you are cleaning the machine

• you are removing the grass clogging the mowing mechanism

• you have run over a foreign object and it is necessary to find out if the machine is not damaged, or to remove the damage

• the machine is vibrating unnaturally in a vigorous manner and it is necessary to find out the cause of vibrations

• you are repairing the engine or other movable parts (disconnect also the cables from the spark plugs)

Before you start t working with the machine, remove all stones, pieces of wood, wires, bones, fallen branches and other foreign objects from the area on
which the mowing will be performed as they can fly out whilemowing. Whenworking, avoid molehills, concrete posts, stumps, garden bed and pavement
curbs as these must not come into contact with the blades in order to prevent damage to the mowing mechanisms or the machine mechanism. In case of
hitting a solid object, stop, turn off the mowing mechanism as well as the engine and check the entire machine, primarily the steering mechanism. If need
be, carry out repairs before restarting the machine. Remove all defects before further use. Before starting the work, thoroughly check the tension of belts,
sharpness of blades and whether it is cleans inside the pressed piece of mowing mechanism. Rotary blades are sharp and can cause injury. Use protective
gloves or wrap the blades when handling them. Check the nuts and bolts fixing the blades on a regular basis and make sure they are tightened with the cor­rect tightening torque (see sectionsection 7.21). Pay increased attention to self-locking nuts. The self-locking ability of the nut is reduced after its second loos­ening, therefore the nut has to be replaced with a new one. The components of the grass collector are subject to strains, they can be damaged, their func­tions worsened and objects may fall out from the bin. Check the components regularly and if needed, replace those components which need to be replaced
according to the recommendation of the machine manufacturer.
Where possible, avoid working with the machine on wet grass.
Avoid obstacles (e.g. a sudden change inslope gradient, ditches etc.) where the machine could turn over.
Operate the machine in day light or under conditions ofgood artificial lighting only.
It is forbidden to run the machine on the public roads.
Do not wear loose clothing and shorts when operating the machine. Use solid, fully closed shoes.

The above illustrated labels and stickers are affixed to the machine.

1.1.1 WORK ON A SLOPE

Slopes are the main cause of accidents, loss of control over the machine or subsequent turning over of the machine that can result in a serious injury or death.
Mowing on a slope always requires increased attention. If you are not sure, or it is above your capabilities, do not mow on a slope. The self-propelled mowing
machine may be used on slopes with a maximum gradient of up to 10°(17%) and only in the direction of the thalweg, i.e. up and down. Riding along the contour
line is not permitted. Changing directions requires increased caution. Do not turn on a slope unless it is necessary. Beware of holes, roots and uneven ground.
Uneven ground may cause the machine to overturn. High grass may cover hidden obstacles. For this reason, remove all obstructing objects beforehand (see pre­vious section 1.1) from the area where the mowing will be performed. Choose such a speed that you will not have to stop on the slope. Perform all moves on the
slope slowly and smoothly. Do not perform any sudden changes in speed or direction. Avoid starting or stopping on a slope. In case the wheels are losing adhe­sion, stop the blade power and ride downwards slowly. When on a slope, be careful and set the mower in motion slowly to prevent from making a "jump." Always
reduce the machine travel speed when approaching a slope, especially when riding downwards. Reduce the travel speed to the minimum in order to utilize the
brake effect of the gearbox.

1.1.2 DO NOT PERFORM

Do not mow near a dump, hollow or banks. The mower may overturn suddenly if a wheel gets over the border of the hollow, ditch or edge, and can tear off.
Do not mow wet grass as the reduced adhesion may cause the machine toskid.
Do not try to maintain stability by stepping on the ground.

1.1.3 CHILDREN’S SAFETY

A tragic accident can happen if the mowing machine operator is not prepared for the presence of children.
The movement of the mowing machine attracts their attention. Never rely on the fact that the children have remainedin the place where you last sawt them
standing.
Do not leave children without supervision in the place where you are mowing the grass.
Be alert and turn off the machine in case the children are approaching it.
Before and during reverse look behind yourself and at the ground.
Never transport children as they can fall down and get seriously injured, or they could hazardously interfere in the machine control. Never permit children
to operate the machine.
Pay extra attention in places with limited visibility (in the vicinity of trees, bushes, walling, etc.).

1.1.4 FIRE SAFETY

With the use of the mowing machine it is necessary to follow the rules and regulations of work and fire safety related to work with this type of machine. Remove

inflammable substances (dry grass, leaves, and likewise) on a regular basis from the area of the exhaust, engine, accumulator and from all places where they
could come into contact with petrol or oil, consequently ignite and set the machine on fire.
Let the engine of the mowing machine cool down before You store it in a closed space.
Pay extra attention when working with petrol, oil and other combustibles. They are highly inflammable matters with explosive vapours. Do not smoke while
working . Never unscrew the cap of the tank and refill the petrol when the engine is running, or if the engine is hot or if the machine is in a closed space.
Check the petrol supply before use, do not fill the petrol up to the tank neck. The temperature of the engine and sun as well as fuel expansivity may result
in an overflow and ensuing fire.
To store combustibles, only use the vessels specified for this purpose. Never store any canister with petrol or the machine inside a building in the vicinity of
any source of heat.
Pay extra attention when handling the accumulator. The gas in the accumulator is highly explosive, therefore do not smoke or use an open fire in the vicni­ty of the accumulator in order to prevent serious injuries.

MACHINE CONTROL ENGLISH

6.2.5 MOWING MECHANISM HEIGHT ADJUSTMENT

Shift the mowing mechanism height adjustment lever 6.1.17 upwards if you want to set up the mowing mechanism higher above the ground, or shift the
lever downwards if you want to set up the mowing mechanism closer to the ground. Position "1" is used to follow terrain unevenness. Do not use this
height adjustmentpermanently as there is danger of increased wear of mowing mechanism componentss. The mowing mechanism is equipped with 4
traversing wheels which lift the frame with mowing mechanism in case of terrain unevenness and thus they serve as protection of the mowing blades
against damage. If you want to lower the controlling force of the mowing system (type AG122)
change the mount of the auxiliary spring to the left side (see pic.).
This setting is applied to all machines by the manufacturer.

6.3 TRAVEL

Before the onsetof travelling, step on the brake pedal 6.1.12 to make sure that the parking brake is disengaged. The parking brake lever 6.1.13 must not remain
in position "B"! The by-pass lever 6.1.15 must be set in position "1", i.e. the by-pass of travel must be disengaged. When travelling to the place where mow-
ing is to be carried out, the mowing mechanism must be switched off and lifted to the highest position, i.e. the lever of the mowing mechanism height adjust­ment must be in position "7." When crossing obstacles higher than 8 cm (curbs, etc.) it is necessary to use ramps in order to prevent damage to the mow­ing mechanism and gearbox.
Perform the drive in the following way:

• Decrease the speed of the engine by shifting the gas control lever 6.1.3 to the "MIN" position.

• When getting started, step on travel pedal 6.1.14 slowly in accordance with the desired direction of the drive - abruptly stepping down on the pedal
increases thedanger of injury.

• Change in drive direction from forward to backward or vice versa is only possible once the machine has stopped. If the machine has not stopped there isdan-

ger of gearbox failure.

• Never use the travel pedal and brake pedal simultaneously - otherwise there is danger of gearbox failure.

6.4 TRAVEL SPEED AND GRASS MOWING

Set the gas control lever 6.1.3 to the "MAX“ position. Adjust the mowing mechanism height using lever 6.1.17 (see section 6.2.5). There is a generally accept-
ed rule that thewetter, higher and denser grass is the lower the speed to be used is. If the speed of the machine is too high, or in the case of a heavy load,
the turning speed of knives decreases, the quality of mowing goes down and the discharge tunnel may become clogged. In such conditions, always set the
motor rpm to maximum. If the grass is too high, the mowing should be done several times. The first cut in the maximum height, or with reduced width of
mowing, and the next cut in the required height. We recommend mowing in the lengthwise as well as crosswise direction. Machine overlapping of thepre­ceding cut enables an increase in the efficiency of knives, and also the look of the mowed area will be improved. Driving on an uneven surface may result in
the variation of speed. With respect to the conditions, we recommend the following speeds:

6.5 TRAVEL ON A SLOPE

This mowing machine may operate on slopes with a gradient of up to 10° (17%). When working on a slope always use a lower speed of travel. Only travel
vertically to the contour line, i.e. upwards and downwards. Travel along the contour line is not permitted. Control the speed of travelling using the gear change
lever. Travel downhill and across the obstacles at lower speed. Changing directions and turning around on a slope requires increased caution. When stopping
the machine on a slope, always use the parking brake. When the machine is being overloaded on slopes with a gradient greater than 10° (17%), it may result
in serious damage to the gearbox. The machine manufacturer does not bear any responsibility for a defect resulting from such use of the machine.

6.6 DISCHARGING OF GRASS COLLECTION BIN

• Stop, apply the brake, and use the parking brake if you are on a slope.

• Switch off the mowing mechanism by the toggle switch 6.1.1. If the AUT/MAN switch is installed in the machine, leave this switch in the "AUT" position.

• Set the gas control lever 6.1.3 to the "MIN" position.

• For machines equipped with manual lifting and lowering of the grass bin, shift the lifting lever 18 up fully (see section 4.2.6), and then use this lever to
tilt the bin. Leave the bin to discharge freely, release it gradually and return it to the initial position.

• For machines equipped with a device for mechanical lifting and lowering of the grass bin, press the switch to
the "LIFTING" position and keep it pressed until the bin is entirely tilted. After the desired position is
reached, release the switch and wait until the bin is discharged. Then switch the switch to the "LOWERING"
position and keep it pressed until the bin is entirely lowered. Once the initial position is reached, release the
switch.

• After lowering the bin into the initial position, switch on the mowing mechanism using the toggle switch

6.1.1. If the machine is equipped with the RESET switch (6.1.10), press this switch to activate the mowing
mechanism.

• The level of basket fullness is signalized by the flap (see pic.). Shift the moveable part of the flap to increase
or decrease the arm length to change the level of basket filling. This is primarily appreciated by persons with
a weaker physique. (The moveable part inserted = maximum level of basket filling and vice versa).

Vegetation condition Recommended speed

high, dense and wet 2 km/hour
average conditions 3 – 5 km/hour
low, dry vegetation < 5 km/hour
travel with disengaged mowing mechanism < 7 km/hour

WARNING !!!

Stopping the machine is only possible by gradually releasing the foot from the travel pedal and then by stepping on the brake pedal. When stepping

on the brake pedal, the travel pedal is automatically moved into neutral position. Upon this, the braking distance is shorter than 2 m. Avoid hard impacts

to the front wheels (hard obstacles etc.). You may damage the front axle, primarily if the impact happens at highspeed!

7.8 FUSE REPLACEMENT

Lift the front bonnet and remove the protective cover. Remove the fuse and insert a new one withthe
same value as the original fuse, i.e. 15A or 20 A. If it is not possible to start the engine or put the
mowing mechanism into operation even after the fuse has been replaced, contact anauthorized
service.

7.9 MACHINE JACK UP

If you want to jack up the mowing machine, use a jack and supports.
When jacking up, proceed as follows:

• Place the jack under the gearbox on the rear axle and jack up the rear part of the machine.

• Put two supports under both ends of the axle inside the side of the rear wheels.

• Jack up the front part of the machine and put two supports under the ends of both front wheel pintles.

• Never try to tilt the machine on the carburettor side. Motor oil may get inside the air filter!

7.10 REPLACEMENT OF MOWING MECHANISM BLADES

The mowing blades must be sharp, statically balanced and straight. These conditions are important for the evenness of the height of mowing and the qual­ity of the cut. A blunt cutting edge worsens both the quality of mowing and the result of mowed grass collection.

Replace the blades as follows:

• Tilt the machine toward the right side and support it. If necessary, dismantle the mowing mechanism.

• Unscrew both blades, clean them and sharpen them. Check the static balance of the blades (see the figure above).

• When reassembling, make sure the bendings of the blades are pointing upwards into the cassing of the mowing mechanism.
Do not confuse the left blade with the right one. The right blade is provided with the screw that has a left-hand thread.

• Check the condition of the shear pins which serve as the protection of the mowing mechanism against damage.
If the shear pins are damaged replace them immediately.

• Tighten the fixing screws of blades thoroughly with the specified tightening torque of 30앐3 Nm. This tightening torque is attained in the moment
when the spring washer under the blade fixing screw is fully pressed and the screw is not further tightened as of this moment.

CAUTION !!

When the blades hit a solid obstacle, stop the engine immediately and check the blades! The shear pins may be damaged or cut.

Replace the cut pins with new ones provided with the machine equipment.

Also check if the fixing screws of the blades are tightened with the tightening torque as specified.

MACHINE MAINTENANCE ENGLISH

7.10.1 SHARPENING THE BLADES

a) The blade may be sharpened with a file or a grinder. Do not performthe sharpening directly on the mowing mechanism. Pay great attention to the align-

ment and balancing of the blades. The vibrations generated by unaligned and unbalanced blades can cause serious damage to the engine or mowing
mechanism. When balancing, insert a screwdriver into the centering hole and set the blade into the horizontal position (see figure 7.10). If the blade
remains in this position, it is balanced. If one of the blade ends is overbalancing, grind this side until the blade is balanced. The permitted static inbal-

ance may be 2g at maximum.

b) TRIPLEX knives

Dismantle the individual blades from the holder and sharpen them separately. Particular care should be taken whenreassembling in order not to con­fuse individual blades. The difference in weight of individual blades can be 2g at maximum.

7.11 STEERING UNIT MAINTENANCE

Check on a regular basis inadmissable clearance between the gear seg­ment of steering and pinion of the steering wheel shaft. If bigger clearance
is detected, eliminate it. Negligence of this maintenance may result in
damage tosteering unit components. When eliminating the clearance, first,
loosen the two M12 nuts 1 on the screw of the eccentric. Apply a suitable
spanner to the eccentric hexagonal head 2 and turn it until the clearance
is eliminated to the minimum. Then, retighten both M12 nuts 1.

7.12 CHECK AND ADJUSTMENT OF TRAVEL DRIVE BELT

The belt is tensioned correctly if it sags approx. by 1.5 cm when the force of 4 kg
is applied in the mid distance between pulleys 1 and 2.

Designation of parts in the figure:

1. engine pulley

2. guiding pulley

3. tension pulley

4. gearbox pulley

Adjustment of belt tension is performed by tightening of nut on the screw tensioning the tension
spring, and then by readjusting screw 3 (fig. 7.11) so that the spring will be tensioned to the length
of 50앐1 mm. Do not overtighten the belt. Too much tension lowers the belt’s operational life!

7.13 CHECK AND ADJUSTMENT OF MOWING

MECHANISM ADJUSTMENT

The correct adjustmentof the mowing mechanism is important to ensurehigh quality mowing.

ORDERING SPARE PARTS ENGLISH

8.1 ORDERING SPARE PARTS

We recommend only using original spare parts which ensure safety and replaceability. Always order spare parts at the authorized dealer or service organization
which is informed of the actual technical changes executed in the products during manufacturing. In the order, always state the serial number to enableeasy,
quick and exact identification of the needed spare part. You will find the serial number recorded on the second page of this manual cover. Also state the year
of machine production which is included on the identification plate located under the seat.

8.2 GUARANTEE

The conditions of guarantee are specified on the certificate of guarantee which is always handed over with the product by the dealer.

9. AFTER-SEASON MAINTENANCE, MACHINE STORAGE

After the end of the season, or if the machine is not used for more than 30 days, it is advisable to prepare it immediately for the storage.
If the fuel stays in the tank without motion for more than 30 days, sticky sediment may form.
This can have an adverse effect upon the carburettor and be a cause of improperfunction of the engine.
This is the reason for emptying the tank.

Recommended procedure of preparations for storing the mowing machine:

• Clean the whole machine thoroughly.

• Replace the faulty or worn out parts and tighten all loosened screws and nuts.

• Prepare the engine forstorage according to the engine operating and maintenance instructions.

• Lubricate all lubricating points according to the lubricating plan (see section 7.6).

• Slacken the V-belt of the mowing mechanism drive (see section 7.14)

• Take out the accumulator, clean it, refill it with distilled water up to the lower parts of filling holes rings and charge it fully.
An uncharged accumulator may freeze and burst. Store the accumulator, if need be, in a cold and dry place.
Charge the accumulator every 30 days and check its voltage regularly.

• Store the mowing machine covered in a clean and dry place.

The best way to ensure the maximum serviceability of the mowing machine for the next season is an annual check and adjustment by an authorized service.

10. MACHINE DISPOSAL

The mowing machine user is obliged to dispose of the machine after the end of its service life. This may be done in two ways:
a) To hand the machine over to a firm which is engaged in this activity (scrap yard, car yard, etc.)

You will receive the due document of handing the machine over to the disposal.

b) To dispose the machine by yourself. In this case we recommend proceeding in the following way:

• Carry out the disposal using secondary raw materials in accordance with the applicable regulations on waste materials.

• Dismantle the machine completely.

• Clean the parts which can be still utilized, conserve and store them for further use.

• Separate the other parts to parts which are ecologically harmless and to parts endangering the environment, e.g. the rubber parts (sealing rings),

residues of lubricants in bearings or gearings. Ecologically harmful components have to be treated in accordance with the applicable regulation­son waste materials valid in the country of the machine user, e.g. in the Czech Republic it is the Law on waste materials no. 185/2001 Coll.

• Separate the disposed material according to Waste Classification in compliance with the applicable regulation. Ecologically harmless parts may

be treated as scrap.

WARNING !!!

Never store the mowing machine with the full tank inside buildings or in badly ventilated spaces where there are fuel vapours,

open fire, sparking or ignition flames, furnace, central heating, dry rags, etc.
