PROTECTION AND SAFETY ENGLISH
1. PROTECTION AND SAFETY OF HEALTH AT WORK
The 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 particularly this Operator's manual. When operating the mowing machine follow meticulously the safety
instructions stated in this manual. In case the machine was used at variance with the instructions and information specified in this manual or with legal
regulations, the manufacturer bears no liability for the contingent damages and the user loses his right to the guarantee repair.
Do not use the machine if any of its protective devices is damaged or missing.
All the covers and other protective devices must always be on their places.
So, do not remove or do not put out of operation any machine protective device.
Check regularly the functions of these devices.
It is not allowed to carry out any technical modification on the machine without manufacturer's approval in writing.
Inadmissible changes can conduce to the hazardous conditions of the safety of work and so to the cancellation of the guarantee.
Do not change the adjustment of the engine speed governor or engine speed limit device.
Do not remove safety stickers or labels from the machine.
Before putting the machine into operation make Yourself thoroughly familiar with all its control elements and master the manipulation
with them in such a way that You will be able to stop the machine or to turn off the engine immediately.
Always keep the machine and its equipment in cleanness and in good technical condition.
Machine can only be driven by a person who is above 18 years of age and is acquainted with the instructions included in this manual.
Machine must not be used for a work on slopes having bigger gradient than 10° (17%).
Machine user is responsible for the safety of persons being in the machine working area.
Do not move in the machine vicinity or under it if it is lifted and it is not properly secured against falling down or turning over.
Machine user is responsible for the safety of persons being in the machine working area.
Do not move in the machine vicinity or under it if it is lifted and it is not properly secured against falling down or turning over.
Transport of other persons, animals or burdens directly on the machine is prohibited.
The transport of burdens is only allowed on a trailer whose type was approved by the machine manufacturer.
If You are leaving the machine even for a short time always withdraw the key from the ignition.
If You operate the machine outside the working area where the mowing is performed turn always the mowing mechanism off
and raise it to the transport position.
If the 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 withdraw the key from the ignition if:
• You are cleaning the machine
• You are removing the clogging of the mowing mechanism with grass
•You have run on a foreign object and it is necessary to find out if the machine is not damaged, contingently to remove the damage
• machine is unnaturally vigorously vibrating 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 sparking plugs)
Before You start the work 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 carried out as they could be flung away during the mowing. During the work avoid the molehills, concrete posts, stumps, patch
and pavement kerbs as these must not come into contact with knives in order to prevent from a damage to the mowing mechanisms or the machine mecha-
nism. In case of striking against a solid object, stop, turn off the mowing mechanism as well as the engine and check the whole machine, especially the steering
mechanism. If need be, carry out the repair before restarting the machine. Remove all defects before further use. Check thoroughly, before starting the work,
especially the tension of belts, sharpness of knives and cleanness inside the pressed piece of mowing mechanism. Rotary knives are sharp and can cause an
injury. At any manipulation with them use protective gloves or wrap them. Check regularly the bolts and nuts fixing the knives and see to it that they are
tightened with the correct tightening torque (see the chapter 7.21). Pay increased attention to the 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 stresses, they
can be damaged, their functions worsened and it can happen that objects may fall out from the bin. Check the components regularly and if needed replace
those components which are to be replaced according to the recommendation of the machine manufacturer.
Where it is possible, avoid the work with the machine in the wet grass.
Avoid the obstacles (e.g. a sudden change of the slope gradient, ditches etc.) where the machine could turn over.
Operate the machine during the day light or at a good artificial lighting only.
It is forbidden to run the machine on the public roads.
Do not wear loose clothing and shorts at the machine operation. Use the solid closed shoes.
Do not operate the machine after consuming alcohol, drugs or medicaments affecting the receptiveness.
Do not operate the machine if You suffer from dizziness, faintness or You are otherwise weakened or unconcentrated.
Do not let the engine run in closed spaces. Exhaust fumes contain the substances which though odourless are deadly poisonous.
Do not start the engine without the exhaust.
Observe all requirements concerning the fire safety stated in the chapter 1.1.4.
Noise generated during the mowing does not normally exceed the highest values of acoustic pressure and acoustic power which are stated in the chapter 3.
"Technical parameters" of this manual. However, the level of noise can be increased, in some cases, for a short time at certain conditions and due to the
property of ground. The machine manufacturer recommends wearing of hearing protection as the exposure to an extremely loud noise or long lasting noise
may cause permanent hearing damage.
Warning !
This self-propelled mowing machine can cut hands, legs or shoot out the objects in case of not observing the safety of work.
Do not place the hands or legs under the cover of the mowing device. Always keep parts of your body away from the rotating or moving parts of the mower.

Above illustrated labels and stickers are fastened on 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 dead.
The 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 the maximum gradient up to 10°(17%) and only in the direction of the thalweg, i.e. up and down. The ride along the
contour line is not permitted. The change of direction requires increased caution. Do not turn on a slope unless it is necessary. Beware of holes, roots and uneven-
ness of the ground. Uneven ground may cause the overturn of the machine. The high grass may cover hidden obstacles. Remove beforehand, from this reason,
all the obstructing objects (see the previous chapter 1.1) from the area where the mowing will be carried out. Choose such a speed You will not have to stop on
the slope. Perform all moves on the slope slowly and smoothly. Do not perform any sudden changes of the speed or direction. Avoid starting or stopping on
a slope. In case the wheels are loosing the adhesion, stop the drive of knives and ride slowly downwards. 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 margin of the hollow, ditch or edge which can tear off.
Do not mow wet grass as the reduced adhesion may by a cause of a skidding.
Do not try to keep stability by stepping on the ground.
1.1.3 SAFETY OF CHILDREN
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 relay on that the children stay in the place where You saw them to stand for the last
time.
Do not leave the children without the 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 reversing look behind Yourself and onto 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, masonry, etc.).
1.1.4 FIRE SAFETY
With the use of the mowing machine it is necessary to follow the rules and regulations for the safety of work and fire safety related to the work with this sort of
machines. Remove regularly the inflammable substances (dry grass, leaves, and likewise) from the area of the exhaust, engine, accumulator and from all
places where they could come into contact with petrol or oil, consequently to inflame 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 whose vapours are explosive. Do not smoke
during this work. 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 supply of the petrol before use, do not fill the petrol up to the tank neck. The temperature of the engine and sun as well as the fuel expan-
sivity may result in an overflow and ensuing fire.
To store the combustibles, use only the vessels specified for this purpose. Never store any canister with petrol or the machine inside the 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 accu-
mulator vicinity in order to prevent from serious injuries.

IMPORTANT
Before turning the ignition off, reduce the engine revolutions to the slow speed in case the self-ignition will occur,
not observing this instruction may result in a damage to the engine and exhaust.
WARNING !!!
Never switch off the mowing mechanism by mere getting off the seat. Unless You switch over the ignition key from the "ON" position
to the "OFF" (STOP) position, the part of the electrical installation is still live and this may cause its fault.

6.2.5 MOWING MECHANISM HEIGHT SETTING-UP
Shift the mowing mechanism height setting up lever of 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.
The position "1" is used for following the terrain unevenness. Do not use this height setting up permanently as there is a danger of increased wear of the
mowing mechanism parts.
The mowing mechanism is equipped with 4 traversing wheels which lift the frame with mowing mechanism in case of a terrain unevenness and thus they
serve as the protection of mowing knives against a damage.
6.3 TRAVEL
Before the start of travelling step on the brake pedal 6.1.12 to make Yourself sure that the parking brake is disengaged. The parking brake lever 6.1.13 must
not stay in the "B" position! The by-pass lever 6.1.15 must be set in the position "1", i.e. the by-pass of travel must be disengaged. At travelling to the place
where the mowing 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 mecha-
nism height setting-up must be in the position "7". At crossing the obstacles higher than 8 cm (kerbs, etc.) it is necessary to use the ramps in order to pre-
vent from a damage to the mowing mechanism and gearbox.
Carry out the drive itself in the following way:
• Decrease the speed of the engine by shifting the gas control lever 6.1.3 to the "MIN" position.
• At moving off, step on the travel pedal 6.1.14 slowly in accordance with the desired direction of the drive - at the fast stepping on the pedal there is
a danger of injury.
• The change of the drive direction from forward to backward or vice versa is only possible after the machine is stopped. If the machine is not stopped there
is a danger of the gearbox failure.
• Never use the travel pedal and brake pedal simultaneously - otherwise there is a danger of the gearbox failure.
6.4 TRAVEL SPEED AND MOWING OF GRASS
Set the gas control lever 6.1.3 to the "MAX“ position. Set up the mowing mechanism height by the lever 6.1.17 (see the chapter 6.2.5).
There is a generally accepted rule that the more wet, higher and denser grass the lower the speed is to be used. 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 clogging of discharge tunnel may occur.
If the grass is too high, the mowing should be done several times. The first cut in the maximum height, contingently with reduced width of mowing, and
the next cut already in required height. We recommend to mow in the longitudinal as well as cross direction. The overlapping of the machine preceding
cut enables to increase the efficiency of knives, and also the feature of the mowed area will be improved.
Driving on an uneven surface may result in variation of the speed.
With respect to the conditions, we recommend the following speeds:
6.5 TRAVEL ON A SLOPE
This mowing machine may operate on the slopes up to the gradient of 10° (17%). When working on a slope use always lower speed of travel. Travel only
perpendicularly to the contour line, i.e. upwards and downwards. The travel along the contour line is not permitted. Control the speed of travelling by means
of the gear change lever. Travel downhill and across the obstacles at lower speed. The change of direction 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 of bigger gradient than
10° (17%), it may result in a serious damage to the gearbox. The machine manufacturer does not bear any responsibility for a defect resulted from such use
of the machine.
6.6 DISCHARGING OF GRASS COLLECTING 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.
•At machines equipped with the manual lifting and lowering of the grass bin, shift the lifting lever 18 (see the chapter 4.2.6) up fully, and then use this lever
to tilt the bin. Leave the bin to discharge freely, release it progressively and return it to the basic position.
•At machines equipped with the device for mechanical lifting and lowering of the grass bin, depress the switch to the "LIFTING" position and keep it
depressed until the bin is entirely tilted. After the desired position is reached, release the switch and wait until the bin is discharged. Then switch over
the switch to the "LOWERING" position and keep it depressed until the bin is entirely lowered. After the home position is reached, release the switch.
•After lowering the bin into the home position, switch on the mowing mechanism by the toggle switch 6.1.1. If the machine is equipped with the RESET
switch (6.1.10), depress this switch to activate the mowing mechanism.

WARNING !!!
The machine stopping is only possible by a gradual releasing of the foot from the travel pedal and then by stepping on the brake pedal. At stepping
on the brake pedal, the travel pedal is automatically moving to the neutral position. At this, the braking distance is shorter than 2 m.
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
