Make sure that all screw connections are tight and secure and will not change position during operation.

A correctly assembled tiller should look as shown in illustration (I).

Preparing for work

-refi lling fuel

The tiller is powered by a fuel mixture designed for two-stroke engines. It is forbidden to use gasoline alone. Gasoline should be mixed with oil in the proportions of gasoline: oil - 25: 1. The mixture should be mixed before pouring into the fuel tank. Mixing and pouring fuel should be carried out away from sources of fire. Do not smoke while refueling. Refueling should be carried out at a distance of at least 3 meters from the place where the device is started and operated.

To protect your engine, use good quality unleaded petrol and good quality oil designed for

two-stroke, air-cooled engines. Do not use oil intended for four-stroke engines. Do not use oil intended for liquid-cooled engines. If fuel is spilled, wipe up any remaining fuel before starting the machine.

Do not use a mixture older than 30 days.

After refueling the tank, close the filler cap firmly and tightly.

- height adjustment of transport wheels (V)

Adjusting the height of the transport wheels involves setting them in one of the three grooves located in the connecting plate. During operation, the wheels should be in the highest groove, while during breaks or transport to and from the workplace - in the middle or lower groove, depending on the height of the operator. To change the position, pull down on the marked point (A) to release the spring and set the appropriate position, then release to lock the wheels in the selected position.

Preparing the workplace

The tiller is used only for tilling the soil. The soil cannot be too hard. If the soil is too hard or dry, it should be moistened before starting work and wait until the water has soaked into the soil.

It is prohibited to work on hard surfaces such as concrete or wood.

Before starting work, remove all visible stones, roots, wires and other things that can damage the tiller blades. Pay special attention to electrical cables. Keep in mind that electrical cables may be hidden underground.

The tiller only works properly when driven forward. Avoid reversing the machine.

Starting and stopping the machine (I)

CAUTION! Do not operate the tiller without the blades and blade guard properly installed.

WARNING! Do not press the throttle lever when starting the machine. Pressing the lever will cause the cutting blades to rotate, which could result in loss of control of the machine, which could result in serious injury. Before starting the engine, make sure that the throttle lever is fully released.

WARNING! To prevent serious injury, never lift or carry the tiller while the engine is running. Always turn the engine off before moving the tiller to another location.

EN

Place the tiller at the starting point. The tiller can only be started when it is in a vertical position.

The tiller's auxiliary wheels should be moved to the upper position as described in the section „Adjusting the height of the transport wheel”.

Warning! The wheel position can only be changed when the engine is switched off.

Set the slotting depth limiter to one of the available positions.

Warning! The limiter position can only be changed when the engine is switched off.

Turn the switch on the right handle to the "I - on" position.

Press the fuel pump 10 times.

Move the choke lever to the upper "CLOSED" position.

Holding the machine handle with one hand, use the other hand to pull the starter rope briskly several times until the engine starts.

Move the choke lever to the "OPEN" position and pull the starter rope briskly until the engine starts.

Do not unwind the rope to its full length, as this may cause it to break. Be careful to pull the starter rope along the axis of the hole, pulling the rope at an angle will lead to premature wear of the starter rope.

To stop the engine, release the throttle button, wait until the cutting element stops rotating, and then turn the switch to the "O - off" position. If you hear any suspicious sounds or feel any vibrations, immediately turn off the tiller by switching the switch to the "O - off" position.

Note! When starting a warm engine, e.g. during short breaks in work lasting up to several minutes, it is not necessary to move the choke lever to the „OPEN” position.

If there is a need to stop the engine in an emergency, the switch should be moved to the „O - off” position, which will stop the engine and consequently the cutting element. However, it should be taken into account that after the machine is switched off, the cutting element may continue to rotate for some time. It is forbidden to stop the cutting element by pressing it to the ground or hitting obstacles.

Working with a tiller

With the engine running and the blades off the ground, pull the throttle lever toward the operating handle to increase engine speed. Caution! Increasing engine speed will cause the blades to rotate. Keep your feet and hands away from rotating parts of the machine.

Holding both handles firmly, slowly lower the tiller until the blades touch the ground. When the tines start to rotate in the soil, drive the machine forward at a moderate pace, allowing the blades to gradually penetrate the ground. After loosening the soil, continue working until you have fully mastered the operation and guidance of the tiller. If you feel resistance, you can stop the machine for a moment, allowing the blades to dig in deeper on their own, or retract it slightly.

When working, you need to be prepared for unexpected situations. The blades may hit a previously invisible stone, root or other obstacle. In such a case, you should immediately turn off the machine, wait for it to cool down and start inspecting. If any damage is detected, further work is prohibited.

Do not apply excessive pressure to the tiller. The blades should not penetrate more than 3 to 4 centimeters.

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.

Attention! Always push the tiller during operation, never pull it towards yourself. Pulling the machine causes the operator to move backwards, which means that he does not control the area behind him.

The tiller should be pushed slowly, always walking, never running. This will provide better control over the machine and reduce the time it takes to react to unexpected events.

When working, move in rows (VI). Keep the rows of equal width, slightly overlapping so as not to miss any space. Be especially careful when changing direction.

Warning! If a foreign object hits the machine during operation. Immediately turn off the machine, wait until the blades stop and the machine cools down. Then check whether the tiller has not been damaged. If damage is detected, do not continue working until it has been repaired. Excessive vibration during operation may be caused by damage to the machine. Stop working, wait until the blades and engine stop. Then wait until the machine cools down and check the product.
