The use and maintenance of garden machinery

The use and maintenance of garden machinery

I. Use and Maintenance of Four-stroke Lawn Mowers 

1. Use unleaded gasoline of grade 90 or above. Never use leaded gasoline, blended gasoline or polluted gasoline. (Note: Refueling should be done outdoors. Smoking is strictly prohibited while the engine is running. Refueling is not allowed during engine operation.) It is recommended to use engine-specific lubricating oil for garden machinery. Four-stroke motorcycle oil is strictly prohibited. 

2. Before using the new lawn mower, it must be run for 2-3 hours for warm-up. For every 45-60 minutes of operation, the machine needs to be shut down for 5-15 minutes. After the warm-up process, the engine oil must be replaced and new oil added. The amount of oil added should not exceed the upper limit indicated on the scale, but must not be lower than the lower limit. Before each use, the oil level must be checked. The engine oil should be changed once every 30 hours (it is best to do this while the machine is hot). 

3. After each use, check the filter element. The machine should have its paper filter replaced or cleaned, and its sponge filter cleaned every 30 hours of operation. In case of severe contamination, it should be cleaned or replaced in advance. 

4. The machine should be shut down for 5 to 15 minutes every 45 to 60 minutes of operation. After each use, the engine and chassis of the machine need to be cleaned. 

5. It is strictly prohibited to use it on slopes with an inclination angle greater than 25°. Due to the excessive slope angle, the oil splash wheel cannot reach the oil, which may result in cylinder seizure (or locking). 

6. Before using the machine, it is essential to clear all debris in the lawn, such as stones, bricks, iron wires, wooden stakes, sprinkler heads, steel pipes, and other objects. 

Safety first! The three key points for maintenance: "Check the oil, clean the filter, and clean the chassis." 

II. Usage and Maintenance of Two-Stroke Hedge Trimmers, Lawn Mowers and Chainsaws 

1. Use gasoline with grade 90 or above. It is best to use two-stroke gasoline engine-specific lubricating oil for garden machinery. Pure gasoline must not be used. 

2. This machine uses a mixture of gasoline and engine oil as fuel. The specific ratio of specialized garden machinery oil is 25:1 or 50:1 (depending on the quality of the oil). 

3. Before using the new machine, it must be run for 1 hour. Every 20-30 minutes of operation, the machine should be shut down for 5-10 minutes. 

4. Every 20 hours of use, you must replenish the grease for the gearbox, transmission, and working head, etc. 

5. Every 40 hours of use, it is necessary to check whether all the screws are loose. If any are loose, please make sure to tighten them. 

6. Before using the machine, the work area should be cleared to prevent any stones, wires, or other debris from being present and potentially endangering the safety of operation. 

7. Maintenance of hedge trimmer blades: Regularly (every 25 hours) check the gap between the upper and lower blades and adjust it in time (the gap is the half-turn pitch of the bolt), to keep the blade edges sharp. Add engine oil to the blade every hour of operation, and trim branches with a diameter of less than 10mm. 

8. Maintenance of the blade head of the brush cutter: The nylon rope head should be kept at a length less than 15 cm. When using the blade, ensure its balance and minimize the vibration of the handle. Never use a blade with vibration when the vibration is significant. 

Safety first! The three key points for maintenance: "Add mixed oil first, add butter second, and clean the filter and blade third."
