Сетуп
1. Распакивање и преглед
Carefully remove the lawn mower and all components from the packaging. Inspect for any shipping damage. Ensure all parts listed in the packing list are present.
2. Склоп ручке
Unfold the handle and secure it in the operating position using the provided knobs or levers. Ensure the handle is locked firmly to prevent movement during operation.

Figure 2: The foldable handle design allows for compact storage. Ensure it is securely locked before use.
3. Додавање моторног уља
Locate the oil fill cap. Remove the cap and slowly pour the recommended engine oil (typically SAE 30 or 10W-30, refer to engine manual for exact type and quantity) into the engine until it reaches the 'FULL' mark on the dipstick. Do not overfill.

4. Додавање горива
WARNING: Use fresh, unleaded gasoline with an octane rating of 87 or higher. Do not use E85 or fuel containing more than 10% ethanol. Never refuel indoors or near open flames.
Remove the fuel cap and fill the fuel tank with gasoline. Do not fill to the brim; leave space for fuel expansion. Securely replace the fuel cap.
5. Attaching Grass Bag (for Rear Bagging)
Lift the rear discharge door and hook the grass bag onto the mower chassis. Ensure it is securely attached to prevent grass clippings from escaping.
Упутство за употребу
1. Провере пре рада
- Проверите ниво моторног уља.
- Уверите се да је резервоар за гориво довољно напуњен.
- Inspect the blade for sharpness and damage.
- Clear the mowing area of any debris, rocks, or foreign objects.
- Ensure all guards and safety devices are in place and functioning correctly.
2. Подешавање висине кошења
The mower features a 6-position height adjustment system. To adjust, pull the single lever located near the wheels outwards and move it to the desired height setting (from 1.5 inches to 3.9 inches). Ensure all wheels are set to the same height.

3. Покретање мотора
- Уверите се да је жица свећице добро повезана.
- Притисните пумпу за гориво (ако је уграђена) 3-5 пута док се гориво не види.
- Померите ручицу сауга у положај „САУГ“ (за хладан старт).
- Hold the engine brake lever against the handle.
- Чврсто и равномерно повуците стартно уже док се мотор не покрене.
- Када се мотор покрене, постепено померајте ручицу сауга у положај „RUN“.
4. Укључивање самоходног погона
Once the engine is running, engage the self-propel lever (typically located on the handle) to activate the rear-wheel drive system. The mower will begin to move forward, reducing the effort required to push it.

5. Mowing Techniques and 3-in-1 System
For best results, mow in overlapping rows. The 3-in-1 system allows for versatile grass management:
- Задње хватање: Collects grass clippings in the attached bag. Empty the bag regularly to maintain collection efficiency.
- Бочно пражњење: Directs clippings out of the side chute. Attach the side discharge chute when not using the bag or mulching.
- Малчирање: Finely cuts and redistributes clippings back onto the lawn as natural fertilizer. Ensure the mulching plug is inserted and the side discharge chute and grass bag are removed.

6. Заустављање мотора
Release the engine brake lever. The engine will stop automatically. Wait for all moving parts to come to a complete stop before approaching the mower.
Одржавање
WARNING: Always turn off the engine and disconnect the spark plug wire before performing any maintenance or cleaning.
1. Редовно чишћење
After each use, clean the underside of the mower deck to prevent grass buildup, which can affect cutting performance. Use a stiff brush or scraper. Clean the engine cooling fins to ensure proper airflow.
2. Моторно уље
Check the oil level before each use. Change the engine oil after the first 5 hours of operation, then every 25 hours or annually, whichever comes first.
3. Филтер за ваздух
Inspect the air filter every 25 hours or more frequently in dusty conditions. Clean or replace as necessary to ensure proper engine performance.
4. Спарк Плуг
Inspect the spark plug annually or every 50 hours. Clean or replace if fouled or worn. Ensure the gap is set correctly according to the engine manual.
5. Нега сечива
Inspect the blade regularly for sharpness, cracks, or bends. A dull blade tears grass, leading to an unhealthy lawn. Sharpen or replace the blade as needed. Always use genuine replacement parts.
6. Складиштење
For long-term storage (over 30 days), drain the fuel tank or add a fuel stabilizer to prevent fuel degradation. Clean the mower thoroughly. Store in a dry, well-ventilated area. The foldable handle allows for more compact storage.
