RESIDUAL RISKS
- Even if you use this product in compliance with all safety requirements, the potential risks of
injury and damage remain. Always be vigilant when using this product, so that you can
recognize and manage the risks rather. The following hazards may arise in the structure and
design of this product:
- There are adverse health consequences resulting from the emission of vibration if the product is
used for long periods of time or not managed properly and properly maintained.
- There is a risk of injury and property damage due to attachments or broken the sudden impact
of hidden objects when using cutting.
- Risk of injury to persons and property caused by flying objects.
- Risk of hearing loss due to a long exposition to noise emitted by the machine.
Prolonged use of this product exposes the operator to vibration and can produce so-called "white
finger" disease. To reduce the risk, wear gloves and keep your hands warm.
If any of the symptoms of "white finger syndrome" occur, seek immediate medical attention.
Symptoms of the "white finger" include numbness, loss of sensitivity, tingling, and pain, loss of
strength, color changes or skin condition. These symptoms usually appear on the fingers, hands, or
wrists. Risk increases at low temperatures.

6. OIL AND FUEL FILLING
WARNING! Engine delivered without oil or fuel: Fill up with petrol and oil before starting the engine.
1) FUEL
Recommended fuel: unleaded petrol with an octane rating of at least 87.
Open the fuel tank cap. Pour the fuel carefully into the tank without overflowing. Never exceed the
maximum level. Then close the tank with its cap.
Wipe off any fuel that may have spilled.
WARNING! Petrol is extremely flammable.
Store fuel in cans specifically designed for this.
Fill the fuel tank only outdoors and before starting the engine. Do not smoke when filling the fuel
tank or handling fuel.
Never open the fuel tank cap and never add fuel when the engine is running or when it is hot.
If fuel has spilled, do not start the engine, move the tool away from where the fuel was spilled, and
take care not to create a spark or flame until the fuel vapors have dissipated.
Close all fuel tank and canister caps completely.
Before tilting the mower to service the blade or drain the oil, empty the fuel tank.
WARNING: Never fill the fuel tank indoors when the engine is running or before the engine has
been able to cool for at least 15 minutes after use.
CAUTION: Do not use unapproved petrol, such as E15 and E85. Do not mix oil with petrol or
modify the engine to run on alternative fuels. Using unapproved fuels will damage engine parts and
void the engine warranty.
To protect the fuel system from scale build-up, add a fuel stabilizer to the fuel.
2) OIL
Recommended oil: SAE 15W-40 4-stroke oil, 0.5L.
Open the oil tank cap. Pour the oil into the tank to the limit. Never exceed the tank limit. Then close
the tank with the cap.
Wipe off any overflow.
OIL LEVEL CHECK
- Check the oil level after the engine has stopped.
- Remove the plug / dipstick from the oil tank and wipe it off.
- Insert the oil tank cap / dipstick into the tank neck without screwing it back, then remove it to check
the oil level.
- If the oil level is close to or below the lower limit of the dipstick, remove the cap / dipstick and fill
the recommended oil tank to the upper limit of the dipstick (lower edge of the neck). Do not overfill.
- Replace the oil tank cap / dipstick

7. OPERATION
Before starting the petrol engine, keep the clutch handle of rotary tiller to the disengaged position.
1) Pull down the supporting wheel frame, detach the limit round rod of support wheel frame from
the slot and rotate upward to the gear position of Cultivation (Fig. 34).
2) Set up the required depth of tilling. 3 different positions are possible. (Fig. 34-1, see the section:
Install the drag strut)
3) Engine cold start
a) Press the primer button 3 times
b) Turn the ON/OFF lever to the CHOKE position (Fig. 35).
c) Pull the starter rope by hand to start the engine and turn the throttle switch to the Working
position (Slow or fast position Fig.36).
Allow the engine to warm for one minute before starting work.
4) Engine hot start
a) Turn the ON/OFF lever to the Slow or Fast position.
b) Pull the starter rope by hand to start the engine
Fig. 33 Fig. 34 Fig. 34-1
Fig. 35 Fig. 36
5) Utilization
a) Do not start walking the rotary tiller until it reaches the predetermined speed, then press the
Supporting
wheel frame
Throttle cable
assembly

clutch handle (Fig. 37) and slowly press its supporting rod into the soil, so that the rotary
blade goes into the soil.
Fig. 37
b) To prevent damage to the rotary blade and related parts, it is strictly forbidden to make the
rotary tiller walk directly when the rotary blade stays in the soil. Do not lower the rotary tiller
rapidly. After the rotary blade goes into the soil, do not go backwards, and make a turn. If
the power supply is not cut off when turning around on end rows, release the clutch handle
of rotary tiller, and at the same time, appropriately reduce the engine speed. Before
crossing fields or walking a long distance, the rotary tiller should be powered off, and the
support wheels should be kept at the hand-push position (Fig. 33). When the rotary tiller is
running, no one is allowed to approach rotating parts, and we should be in a safe place
behind the rotary tiller.
c) Power off before checking the rotary tiller. The engine must be turned off before replacing
rotating parts such as blades. During plowing, the forward speed should be preferably 2~3
km/h in dry fields, and 4~5 km/h in ploughed or harrowed fields. Remember to avoid high
speed to prevent damage to the power take-off shaft due to engine overload. If, during the
operation, the cutter shaft is wrapped with too much grass, stop in time to clean up, so as
not to increase the load of the machine. During rotary tillage, pay attention to the stones in
the soil which may cause accidental damage to the rotary tiller.
6) Stop the engine
Put the ON/OFF lever to the "O”position. Move the wheels down (Fig.33) to move the tiller

8. INSPECTION AND MAINTENANCE
Warning! Always clean the appliance after use. Failure to clean it properly may cause
damage to the unit or cause malfunction.
Warning! Injuries may occur during work on teeth. Wear protective gloves.
Before carrying out any maintenance, switch off the appliance and allow it to cool down.
GENERAL MAINTENANCE
- Check that the tool is not damaged.
- Check that there are no materials or objects that could be jammed on the blades.
- Clean the body with a damp cloth or a soft brush. Remove all materials and objects that may
obstruct ventilation.
- Check transmission lubricant after each use or after 40 hours of operation. Replace lubricant if
necessary.
- Check the condition of the cutting teeth and make sure that all connections are tight. If the teeth
are dull, contact a specialist workshop to repair them if necessary.
- Whenever possible, clean the appliance immediately after you have finished working.
- Clean the underside of the housing around the teeth and the protective plate as well as the
bumper with a brush and brush or a soft cloth soaked in mild soap mixed with water. Never
splash with water!
- Remove dirt and debris from teeth and transmission, use a brush or damp cloth.
- Worn teeth make the performance bad and may cause the engine to overload; Remove them to
clean them. Once cleaned, wipe the teeth and shaft, and apply a light coat of oil.
PERIODIC / SEASONAL MAINTENANCE
- After 150 hours: clean the gear housing and replace the oil.
- After 800 hours: Check all parts of the tool and have it repaired or replaced by a qualified
technician if necessary.
- Once a season: Grease the teeth and the tree.
- At the end of the season, check the unit and have it serviced in a specialized workshop.
MAINTENANCE OF THE AIR FILTER
Warning! Do not use petrol or abrasive products to clean the air filter.
A dirty air filter prevents air from entering the carburetor and prevents proper operation of the
carburetor. Air filters must be maintained regularly:
- Press the buckle and remove the air filter cover, and then remove the air filter.
- Using a mild soap solution and water to clean the air filter. Dry it.
- Replace the air filter and cover.
9. TRANSPORTATION AND STORAGE
Clean the unit thoroughly before storing.
Do not lift the machine, move it by rolling it while holding both handles.
Store the device in a clean and dry place. The machine must be turned off and cooled.
The fuel or oil may leak during transport. Secure the unit properly and take preventative
measures to protect the environment from contamination.
