Pull out both transmission override levers (a), turn them clockwise (b) and lock them in place, as shown in illustration (II). Once the machine has been moved, disengage the transmission override levers by performing steps (a) and (b) in reverse order.

Installing the operator protection frame (I)

The operator's protective frame must be mounted to the brackets located behind the operator's seat using the mounting screws and nuts. It is prohibited to use the machine without a properly mounted protective frame.

Installing and adjusting the operator's seat

To assemble the operator's seat, follow the instructions below. First, remove all the straps securing the seat assembly and control levers for transport. Be especially careful not to damage the wiring harness connecting the microswitch located under the seat to the operator presence detection system on the seat. Then, unscrew the two screws and two knobs located on the seat base. After completing these steps, the seat should be turned to the correct position and pre-secured to the guides using previously unscrewed screws (a) and knobs (b) as shown in illustration (III). Adjusting the seat to the operator's height is possible in several available positions by securing the seat in the appropriate holes in the guides using the fastening knobs. It is recommended to make the final adjustment of the seat after all the machine components have been completely assembled. After completing the adjustment, tighten the screws and knobs securing the seat to the guides firmly and securely and make sure that the seat does not change its position during operation.

During installation, be careful not to pinch or damage the wiring harness.

Assembly and adjustment of the machine drive control levers

The machine's drive control levers have been lowered or dismantled for transport. Before using the tractor, they must be properly installed and set. These levers can be mounted in one of two available height positions and can be moved forward or backward within the slot in the bracket, adjusting their position to ensure comfortable operation of the machine.

As shown in illustration (IV), attach the lever (a) to the bracket (b), and then attach the connected parts to the lever holder (c) using the mounting screws (d) and nuts (e), without fully tightening the screws. After completing these steps, make sure that the control lever (a) is in line with the lever holder (c), and then repeat the above steps for the other lever so that the other control lever is attached and set in the same position. After completing the adjustment of both control levers, tighten the mounting screws firmly and securely to prevent the levers from moving during operation.

Installing the side discharge guard

CAUTION! Operating the machine without the side discharge guard or with the side discharge guard incorrectly fitted is prohibited. The guard must be in the lowered position during operation.

The connectors can only be connected in one correct way. Make sure that the battery is properly secured to the base in the machine frame using the mounting clamp and mounting screws and that it does not change position during operation.

PREPARING FOR WORK

NOTE! The engine may only have a small amount of oil in it from the factory to protect it during transport and storage. Before first start-up, check the engine oil level and then top up to the required level. The oil level should be checked

EN

regularly and topped up as necessary. Starting the machine without oil or with too little oil in the gearbox can lead to irreversible engine damage.

You should prepare oil intended for four-stroke engines with a viscosity class of SAE 15W40.

Before adding oil, place the machine on a flat surface, open the engine cover, and then, as shown in the illustration (XXII), unscrew the oil filler cap and wipe the attached oil dipstick dry. Fill the tank with oil. When filling, it is recommended to use a funnel or a filler to avoid spilling oil. If oil spills, wipe off any residue before starting the engine. Check that the oil level is correct. To do this, insert the dipstick into the filler hole and screw on the oil filler cap. Then unscrew it and check the oil level on the dipstick. The oil level should be between the maximum and minimum levels on the dipstick (XXII). After making sure that the oil level is correct, close the oil filler hole with the cover.

NOTE! The oil level should be checked before each start of work. Never check the oil level while the engine is running. Stop the engine before adding oil.

After adding oil, add fuel. The fuel is unleaded petrol with an octane rating of at least 95. To add fuel, unscrew the fuel tank filler cap as shown in illustration (XX) and pour fuel into the tank. When adding fuel, it is recommended to use a filler or funnel to reduce the risk of fuel spilling. If fuel spills, wipe off any remaining fuel thoroughly. Wait until the vapors have completely dissipated and start the engine in a different place than where fuel was filled. After adding fuel, close the fuel tank filler cap. After adding oil and fuel, close the engine cover.

The rear axle of the tractor is equipped with pneumatic wheels. The recommended tire pressure is 24 PSI / 1.65 BAR. The tires must be inflated before starting work. Do not exceed the recommended tire pressure. Always inflate the tires to an even pressure. Incorrect or uneven tire pressure can cause uneven mowing and lead to dangerous situations such as the machine tipping over on its side, which can cause serious injury or even death.

NOTE! Before each start of work, check that the air pressure in the tires is correct.

Before starting work, check that the machine is not damaged, is properly assembled and that all safety elements are properly attached. If it is found that the machine is incomplete or damaged, further work is prohibited!

From the work area, remove all visible stones, roots, wires, toys and other obstacles that can be caught by the machine blades and thrown in another direction. Special attention should be paid to electrical wires so that they do not end up in the work area. Leaving electrical wires in the work area can lead to damage to the wires, which can result in electric shock or even death.

Battery charging

CAUTION! The battery must be charged away from sources of fire. Do not smoke while charging the battery. Keep the battery away from sparks. Ignition of gases released from the battery may cause the battery to explode.

CAUTION! Never start the engine unless the battery is fully charged. Before starting the engine, make sure the battery is fully charged.

CAUTION! Before starting charging, make sure that the power supply body, cable and plug are not cracked or damaged. It is forbidden to use a faulty or damaged charger! Only the charger supplied with the machine may be used to charge the battery. Using another charger may cause a fire or irreversible damage to the battery. The battery may only be charged in a closed, dry room protected from access by unauthorized persons, especially children. The charger must not be used without constant adult supervision! If it is necessary to leave the room where charging is taking place, disconnect the charger from the mains by unplugging the power supply from the mains socket. If smoke, a suspicious smell, etc. is emitted from the charger, the charger plug must be removed from the mains socket immediately!

The mower is equipped with a maintenance-free lead-acid battery that does not require electrolyte level control. In the event of longer storage, e.g. during the winter, it is recommended to charge the battery once every three months to prevent damage due to discharge. In the event of a situation in which starting the machine is difficult or impossible, the battery should be charged. If the battery cannot be charged, it should be replaced with a new one. The battery should always be replaced with an original one, identical to the one that was factory-fitted to the mower. The used battery should not be disposed of with household waste, the battery should be disposed of in accordance with local regulations.

To ensure a long battery life, it is important to maintain it carefully. Failure to follow this procedure or charging the battery incorrectly can cause permanent damage to its components. The device's battery must always be charged:

• before using the device for the first time after purchase.
• before leaving the device unused for a long period of time.
• before starting the device after a long period of non-use.
• a discharged battery should be charged as soon as possible.

The machine is equipped with a battery charging socket located under the operator's seat. To charge the battery, raise the operator's seat, connect the charger plug to the battery charging socket, and then connect the charger to the mains socket. The red diode will light up, indicating the charging process. When charging is complete, the red diode will turn off and the green diode will light up, indicating the battery is fully charged. Unplug the charger plug from the mains socket, and then disconnect the charger plug from the battery charging socket. When the battery is charged, close the engine cover.

Below is a description of the machine controls, shown in illustration (VIII):

a. Machine Drive Control Levers - The right and left drive control levers are located on either side of the operator's seat and provide forward (D) and reverse (R) travel. The levers are hinged, allowing them to swing outward to allow the operator to enter or exit the tractor. To start the engine, the levers must be fully outward, in the neutral (N) position, which also engages the parking brake. Each lever controls the corresponding drive transmission – right or left, controlling all the movements of the tractor. Driving and steering the tractor using these levers is different from operating traditional tractors and requires practice. Detailed instructions on how to operate the levers are provided later in the manual.

b. Cutting height adjustment lever – this lever allows you to change the cutting height within the range given in the technical data table. The lever can be set in one of 6 cutting height adjustment positions, where position 1 corresponds to the lowest and position 6 to the highest possible cutting height. To change the cutting height, move the lever sideways by sliding it out of the guide bar socket, and then after setting the desired height, move the lever sideways, locking it in the guide bar socket.

Attention! Attention! Before driving the mower on a road or sidewalk, raise the cutting unit to the maximum cutting height and disengage the blade drive.

c. Ignition switch – used to start and stop the engine using the key. To start the engine, place the key in the ignition, turn and hold the key in the position marked with the start symbol – START, until the engine starts, then immediately release the pressure on the key. To turn the engine off, turn the key to the off position – STOP.

d. Blade drive switch – this switch allows you to engage or disengage the blade drive. Lifting the switch up will engage the blade drive, which will cause the blades to start rotating. Pressing the switch down will disengage the blade drive.

ATTENTION!

The blades may continue to rotate for a few seconds after the blade drive is disengaged.

Before starting the engine, make sure that the blade drive is disengaged – the blade drive switch should be pressed in.

Always keep hands and feet away from rotating blades, discharge chute and moving engine parts.

Before leaving your position, disengage the blade drive and make sure the blades have stopped rotating.

Always disengage the blade drive before driving the machine on a sidewalk or road.

e. Throttle control lever – allows you to increase or decrease engine speed. To start a cold engine, push the throttle lever all the way forward to the choke position, marked with a hare symbol. As the engine warms up, set the lever to a position between the hare symbols (faster RPM) and the tortoise symbols (slower RPM). After each change of throttle lever position, wait until the engine is running smoothly. The speed at which the throttle lever returns depends on the atmospheric conditions in which the engine is started. The lower the ambient temperature, the slower the return must be.

During normal operation and when mowing grass, increase the engine speed by moving the throttle lever to the position marked with the hare symbol. When moving from one mowing area to another, it is recommended to set the lever to the position between the hare and tortoise symbols.

Note! The maximum engine speed that can be set using the throttle lever is factory-set for maximum engine performance. Do not change the sealed engine speed settings. Increasing the factory-set engine speed can damage the machine's engine or even cause a fire.

Machine safety system

The machine is equipped with a safety system that protects the operator from potential hazards during use. If the safety system is not working properly, do not use the machine until it is repaired.

The safety system prevents the engine from starting unless the right and left drive control levers are fully outward in the neutral position and the blade drive is disengaged.

The safety system automatically turns off the engine if the operator leaves the seat with the blade drive engaged.

Note! The blade drive must be disengaged to restart the engine.

The safety system disengages the blade drive and stops the mower blades from rotating if both drive control levers are moved to the reverse position. To re-engage the blade drive, the levers must be in neutral or in the forward position and the blade drive switch must be pressed to disengage the blade drive and then lifted to re-engage the blade drive.

Machine safety system check procedure

Note! Some checks may only be possible after starting the engine. The procedure for starting the internal combustion engine is provided later in this manual.

Regular inspection of the safety system is essential to ensure the machine is working properly. To perform the inspection, follow these steps:

Engage the blade drive. Then momentarily turn the ignition key to the start position – the engine should not start.

Move both drive control levers fully inward to the neutral position, then release the operator seat – the engine should stop.

EN

Set both drive control levers fully out to neutral (with the parking brake engaged), engage the blade drive, then release the operator's seat - the engine should stop.

Start the tractor and set the drive control levers to neutral. Engage the blade drive and slowly move both drive control levers backwards, slowly moving backwards – the blade drive should disengage and the mower blades should stop.

After performing the above tests, make sure that all safety system functions are working properly. If any irregularities are detected, immediately stop using the machine and contact the manufacturer's authorized service.

Checking machine safety and performance

Before starting work, check that the machine is not damaged, is properly assembled and prepared for work and that the safety system is working properly. If it is found that the machine is not properly prepared for work, is incomplete, has damage or any of the safety systems do not work properly, further work is prohibited!

Do not start mowing if you feel excessive vibration from the cutting blades or if you are not sure that the blades are sharp enough. Poorly sharpened blades tear the grass and cause the lawn to turn yellow. A loose, damaged or incorrectly fitted blade can cause vibration and also cause dangerous situations!

Starting the combustion engine

WARNING! The machine is equipped with a safety system to protect the operator. Do not use the machine if any of the safety system components are not working properly. The safety system should be checked regularly to ensure safe operation of the machine.

NOTE! Before starting the engine, make sure that the blade drive is disengaged – the blade drive switch is pressed.

Take the operator position on the seat.

According to illustration (IX):

Make sure the left (a) and right (b) machine drive control levers are fully outward in the neutral position (parking brake engaged). Make sure the blade drive is disengaged – the drive switch (e) is pressed.

Note! If the engine is warm, it may not be necessary to move the throttle lever (c) to the choke position, marked with the hare symbol, to start the engine.

Move the throttle lever (c) fully forward to the choke position, marked with the hare symbol.

Insert the key into the ignition (d) and turn it clockwise to the START position, then release the key immediately after the engine starts. Do not crank the engine continuously for more than 5 seconds. If the engine does not start within this time, turn the key to the STOP position and wait at least 15 seconds for the starter to cool down. After this time, try again. If after several attempts the engine still will not start, do not continue cranking with the throttle valve in the choke position, as this could flood the spark plug and make restarting the engine difficult.

After starting, as the engine warms up, set the throttle lever (c) to a position between the hare symbols (faster RPM) and the tortoise symbol (slower RPM). After each change of the throttle lever position, wait until the engine is running smoothly. The speed of the throttle lever return depends on the weather conditions in which the engine is started. The lower the ambient temperature, the slower the return must be.

Before starting work, make sure that the engine runs smoothly.

Stopping the combustion engine

According to illustration (IX):

Make sure the blade drive is disengaged – the drive switch (e) is pressed.

Make sure the left (a) and right (b) machine drive control levers are fully outward in the neutral position (parking brake engaged).

Set the throttle lever (c) to the mid-position between idle and maximum engine speed.

Turn the ignition key (d) counterclockwise to the STOP position, then remove the key.

Caution! Always remove the key from the ignition after stopping the engine to prevent accidental engine starting and battery discharge when the machine is left unattended.

First use – exercises before starting work

Operating a zero-turn tractor is different from operating a traditional self-propelled tractor. Because a zero-turn tractor is more maneuverable, it takes some practice to master the controls.

It is recommended to designate a suitable, level place for practice in an open area, to which no unauthorized persons or animals will have access. Before starting to use it, it is recommended to practice operating the tractor for about 30 minutes.

Carefully transport the tractor to the designated practice area. The blade drive should be disengaged during practice. During practice, operate the throttle lever at approximately 1/2-3/4 of the full range and do not use maximum speed in either forward or reverse. Practice carefully maneuvering the tractor according to the information below on operating the tractor. Practice until you can safely operate the machine.

Preparing to drive a tractor

WARNING! When operating the machine, avoid sharp turns, excessive speed and sudden stops.

Make sure the operator's seat is adjusted to the most comfortable position to allow easy access to the controls. For detailed seat

EN

adjustment information, refer to the „Assembling and Adjusting the Operator's Seat „ section of the manual.

As shown in illustration (X), move both drive control levers (a) fully inward to the neutral position, which will release the parking brake.

Note! The drive control levers must be moved fully inward to the neutral position before you can start moving forward or reverse. In this position, the parking brake is released. Parking the tractor on uneven ground or on a slope can cause the brakes to lock. If this happens, the tractor will not move until the levers are reset. In this situation, gently move the levers in the opposite direction to relieve the load on the brakes and allow them to release completely.

Note! If the control levers are not in the neutral position, the control levers must be readjusted as described in the instruction section „Assembly and adjustment of the machine drive control levers”.

Move the throttle lever to the maximum engine speed position, marked with the hare symbol.

Note ! Although the machine's engine is designed to operate at its maximum possible RPM, it is recommended to operate the tractor at a lower RPM setting during practice, gradually increasing it as you gain experience.

WARNING! Always keep your hands on the drive control levers. Do not release the levers by releasing them to slow the tractor. Use your hands to move the levers to the neutral position.

To begin moving forward, firmly grasp both drive control levers, then follow the instructions below.

Driving the tractor forward

WARNING! All movements of the drive control levers should be performed slowly and smoothly. Sudden movements of the levers can affect the stability of the tractor and cause it to tip over, which could result in serious injury or death to the operator.

According to the illustration (XI):

Slowly and evenly move both drive control levers (a) slowly forward. The machine will begin to move forward.

The further the drive control levers (a) are moved forward, the greater the tractor's travel speed.

To slow down the machine, move the drive control levers slowly rearward or move them to the neutral position to stop the machine.

WARNING! Always keep your hands on the drive control levers. Do not release the levers by releasing them to slow the tractor.

Use your hands to move the levers to the neutral position.

Turning the tractor while driving forward

WARNING! When changing direction, it is recommended to make gradual U-turns where possible. Sharper turns increase the risk of turf damage and may affect tractor control. Always slow down before making a sharp turn.

To turn the tractor while driving forward, the drive control levers must be moved accordingly – one lever should be moved backwards relative to the other. The tractor will turn in the direction of the lever moved backwards.

To turn left, move the left drive control lever rearward relative to the right, as shown in illustration (XII).

To turn right, move the right drive control lever rearward relative to the left, as shown in illustration (XIII).

The greater the difference in position between the two levers, the sharper the tractor will turn.

To rotate around your own axis, move the lever responsible for the steering direction to the neutral position while simultaneously moving the other lever forward.

Note: Performing a spin on grass can significantly increase the risk of damaging the turf.

Driving a tractor backwards

WARNING! Before reversing, make sure that the area around the machine is clear of obstacles and bystanders, children and animals. Do not turn near building walls, trees or other fixed obstacles to avoid dangerous situations. Be especially careful when reversing and always look to the rear.

Before reversing, stop the tractor by moving both drive control levers to the neutral position (a). Once the machine has come to a complete stop, slowly and evenly move both drive control levers rearward as shown in illustration (XIV). The tractor will begin to move in the opposite direction.

The further the drive control levers are moved rearward, the greater the tractor's travel speed.

To slow down the machine, move both drive control levers slowly forward or move them to the neutral position to stop the machine.

Turning the tractor while driving backwards

To turn the tractor while reversing, the drive control levers must be set correctly – one lever should be moved forward relative to the other. The tractor will turn in the direction of the lever moved forward.

To turn left while reversing, move the left drive control lever forward relative to the right, as shown in illustration (XV).

To turn right while reversing, move the right drive control lever forward relative to the left, as shown in illustration (XVI).

The greater the difference in position between the two levers, the sharper the tractor will turn.

To turn around your own axis, move the lever responsible for the turn direction to the neutral position while simultaneously moving the other lever rearward.

Note: Performing a spin on grass can significantly increase the risk of damaging the turf.

Making a zero radius turn

WARNING! The tractor must be completely stopped when making a zero turn. Making a zero turn while the tractor is moving can significantly reduce control of the machine and lead to serious damage to the lawn.

EN

Stop the tractor by moving both drive control levers to the neutral position.

To turn right (clockwise), move the left drive control lever forward while moving the right lever rearward, as shown in illustration (XVII).

To turn left (counterclockwise), move the right drive control lever forward while moving the left lever rearward, as shown in illustration (XVIII).

Stopping the tractor

Move both drive control levers to the neutral position to stop tractor movement.

Disengage the blade drive by pressing the blade drive switch.

Raise the cutting deck to the highest cutting height using the cutting height adjustment lever.

If it is necessary to leave the tractor, move the drive control levers fully outward to the neutral position, which will engage the parking brake. Then move the throttle lever to the idle position and turn the engine off by turning the ignition key to the STOP position and removing it.

WARNING! Do not leave the operator's seat without first disengaging the blade drive and setting the drive control lever outward to neutral with the parking brake engaged. Always turn off the engine and remove the key from the ignition when leaving the tractor unattended.

Blade drive operation/mowing

WARNING! Do not engage the blade drive when the cutting unit is in a low position on the grass. This can result in premature wear of the belt drive and the blade drive clutch. Before engaging the blade drive, raise the cutting unit completely or move the tractor to an area without grass.

To engage the blade drive:

Move the throttle lever to the medium speed position in the medium speed position.

Lift the blade drive switch to the on position.

Move the throttle lever to the maximum engine speed position.

Move the drive control levers forward slowly and steadily to move the tractor toward the designated point while maintaining the appropriate operating speed.

The operator must remain in the seat at all times when the machine is in operation. If the operator leaves the seat without first disengaging the blade drive, the tractor engine will shut down.

Blade drive cannot be engaged when the tractor is in reverse. Drive will automatically disengage when both drive control levers are moved to the reverse position. To re-engage the blade drive, the levers must be in neutral or forward position and the blade drive switch must be pushed to the disengaged position and then lifted back to the engaged position.

CAUTION! Always keep hands and feet away from the rotating blades, discharge opening and moving engine parts. Before leaving the operator's position, disengage the blade drive and make sure the blades have come to a complete stop. Always disengage the blade drive and raise the cutting unit to the highest position before driving the tractor on a sidewalk or road.

Recommendations when working with a lawn mower

Before starting work, prepare the area where the grass will be cut. Check that the area where the grass will be cut is free of any obstacles that could be caught by the blade and damage the mower or be thrown out and pose a hazard to the operator or bystanders.

Check the work area for electrical cables that could be cut by the blade. Damage to an electrical cable creates a risk of electric shock, which could result in serious injury or death.

Make sure that there are no bystanders or pets in the work area. If such people appear during work, first stop the mower immediately and only then warn them about the danger.

Avoid working on unstable surfaces and use caution when working on slippery surfaces.

When working with the mower, it is recommended to move the rows as shown in the illustration (XIX), maintaining equal strip widths, which should overlap slightly to ensure an even cut and avoid missing any spots.

At the end of each pass, reduce speed or stop the tractor before making a turn. It is recommended to make U-turns unless a zero turn is necessary.

Before performing a zero turn, reduce speed and then come to a complete stop.

The speed of the tractor affects the quality of the cut. Driving too fast can worsen the cutting effect. The speed should be controlled using the drive control lever.

Operate the drive control levers smoothly and avoid sudden movements when starting and stopping.

For better cutting performance and quality, it is recommended to set one of the lowest ground speeds and the highest engine speed.

Check the length of the grass and choose the cutting height. If the grass is very tall or dense, cut it in stages. Never cut more than 1/3 of the grass length. Mowing should be done regularly, making sure that the grass height does not exceed the mower's capacity. Never cut wet grass. Wet grass tends to stick inside the product, which prevents it from collecting in the basket.

Before reversing, make sure that the area around the machine is clear of obstacles and bystanders. Do not turn near building walls, trees or other fixed obstacles to avoid dangerous situations. Be especially careful when reversing.

Check all mower components before starting work. If damage is observed, do not start work until it has been removed or the damaged components have been replaced with new ones. Check that the ventilation holes are clear. If necessary, clean them with

EN

a soft brush or paintbrush. Do not use sharp or metal objects to clean the mower's ventilation holes.

Check that the screw connections are not loose. Tighten if necessary.

Check that the mower controls are clean and free of grease and other contaminants. Clean with a soft cloth if necessary.

Take regular breaks during work to avoid fatigue and overwork. This will allow you to better control the product and reduce the risk of accidents.

For better machine control, always set a safe driving speed.

Exercise particular caution when changing direction.

After finishing work, stop the machine, disengage the blade drive, make sure that both machine drive levers are fully tilted outwards in the neutral position, then stop the engine and remove the ignition key. Wait for the machine to cool down completely, disconnect the spark plug wire and start maintenance.

WARNING! If a foreign object strikes the mower during operation. Immediately stop the machine, disengage the blade drive, make sure that both machine drive levers are fully outward in the neutral position, stop the engine and remove the ignition key. Wait until all components have cooled down completely, then disconnect the spark plug cable. Then check the machine for damage. If damage is detected, do not continue working until it has been repaired. Excessive vibration during operation may be caused by damage to the mower. Stop work, disconnect the spark plug and inspect the product.

Working on the slopes

WARNING! Do not operate on slopes steeper than 10 degrees. The tractor may tip over, causing serious injury or death.

Recommendations for working on slopes

Mow across the slope, not up or down. Be especially careful when changing direction on a slope.

Watch for holes, ruts, bumps, rocks and other hidden obstacles. Uneven terrain can cause the machine to tip over. Tall grass can hide obstacles.

Use low speed. Selecting a suitably low ground speed will avoid having to stop on a slope. If traction is lost, disengage the blade drive and drive carefully down the slope.

All maneuvers on slopes should be performed slowly and smoothly. Sudden changes in speed or direction could cause the front of the tractor to lift or tip over backwards.

Things to avoid

Avoid turning when going downhill if possible. It is recommended to start at the bottom of the slope and work your way up, always slowing down before turning.

Do not mow near slopes, ditches or embankments. The tractor may suddenly tip over if a wheel is on the edge of a drop-off.

Do not attempt to stabilize the machine by placing your foot on the ground.

Do not mow wet grass. Reduced traction can cause the machine to skid.

Refueling

WARNING! Fuel is highly flammable! Observe all safety precautions when handling fuel. Do not fill the fuel tank while the machine is running. Allow the engine to cool before refueling. Do not refuel near an open flame. Do not smoke in the refueling area. Do not spill fuel. If fuel is spilled, wipe up the fuel thoroughly before starting the machine. Tighten the fuel filler cap securely. Store fuel in tightly closed, approved containers away from heat sources and out of the reach of children.

Stop the engine according to the procedure described in "Stopping the Internal Combustion Engine".

Wait for the engine to cool down.

To refuel, unscrew the fuel tank cap as shown in illustration (XX) and pour fuel into the tank. Do not fill the fuel tank above the top of the fuel tank. When filling the fuel, it is recommended to use a filler neck or funnel to reduce the risk of fuel spilling. If fuel spills, wipe off any remaining fuel thoroughly. Do not overfill the fuel tank. Wait until the vapors have completely dissipated and start the engine in a different place than where the fuel was filled. After filling the fuel tank, close the fuel tank filler neck with the cap.

Restart the engine according to the procedure in section „ Starting the combustion engine".

MACHINE MAINTENANCE

WARNING! Before performing maintenance or adjustments on the mower, stop the machine, disengage the blade drive, make sure both machine drive levers are fully outward in the neutral position, disengage the blade drive, stop the engine and remove the ignition key. Allow all components to cool completely, then disconnect the spark plug wire.

Leveling the cutting unit

Transverse leveling of the cutting unit

Note! Before adjusting the level of the cutting unit, check the air pressure in the tractor tires. For detailed information on pressure values, see the PREPARING FOR WORK section.

Always level the cutting unit crosswise (left to right) first, and only then adjust its position lengthwise (front to back). If the blades are not cutting evenly, you can correct the level of the cutting unit by adjusting it crosswise.

Adjust as follows:

Stop the tractor on a firm, level surface. Set the cutting height lever in the middle position, between the lowest and highest cutting heights, then rotate both outer blades so that they are perpendicular to the tractor.

Measure the distance from the tip of the left blade to the ground, then the distance from the tip of the right blade to the ground.

The two measurements should be identical. If the values are different, proceed to the next step.

Loosen the screw (a), adjust the height, and then tighten the nut (b) as shown in illustration (XXXVI).

Note! The rear right mower suspension mount is non-adjustable and is used to assist in adjusting the other suspension mounts.

Longitudinal leveling of the cutting unit

Note! Before adjusting the level of the cutting unit, check the air pressure in the tractor tires. For detailed information on pressure values, see the PREPARING FOR WORK section. Always first level the cutting unit laterally (from left to right), and only then adjust its position longitudinally (front to back).

The front of the cutting unit should be 6-10 mm lower than the rear. If adjustment is necessary, follow these steps:

Stop the tractor on a level, firm surface and set the cutting height adjustment lever in the midway position between the lowest and highest cutting heights.

Turn the blade closest to the discharge opening so that it is parallel to the tractor.

Measure the distance from the front end of the blade to the ground and from the rear end of the blade to the ground. The first measurement should be 6–10 mm less than the second measurement.

Determine the approximate value of the adjustment required and, if necessary, proceed with its execution.

The illustration (XXXVII) shows: (a) nut, (b) bolt. Loosen the nut (a), then adjust the bolt (b). After adjustment, tighten the nut.

Adjusting the front guide wheels of the cutting unit

WARNING! Keep hands and feet away from the cutting unit discharge opening.

The front guide wheels of the cutting unit are designed to prevent scalping of the lawn and should not touch the ground. The height of these wheels relative to the ground should be 6-13 mm after the cutting unit has been set to the desired cutting height.

Use the cutting height adjustment lever to set the cutting unit to the desired working height, then check the distance of the guide wheels from the ground. If adjustment is necessary, follow the steps below:

EN

Visually check the distance between the front guide wheels and the ground.

If the wheels are touching the ground or very close to it, they should be lifted.

If the wheels are more than 12 mm above the ground, they must be lowered.

Unscrew the nut securing one of the front guide wheels and the bolt securing the wheel to the cutting unit. Remove the guide wheel and the securing bolt as shown in illustration (XXXVIII).

Screw the mounting screw into one of the four holes in the guide wheel holder to ensure that the wheel clearance is 6–12 mm from the ground.

Note which hole the first guide wheel is mounted in and adjust the second wheel accordingly so that it is at the same height.
