What are the maintenance jobs of lawn mower?

Abstract: Lawn machine refers to a kind of mechanical equipment and environmental protection equipment used for mowing and greening. It can cut grass and weeds in the garden, dry them, and use the recovered hay as animal feed. When using the lawn mower, you need to pay attention to the correct mowing method, and it is forbidden to operate with one hand, so pay attention to safety when using it. How to maintain the lawn mower after use? The maintenance of lawn machine includes daily maintenance, regular maintenance and maintenance. Let's take a look at the use and maintenance of lawn mower! Matters needing attention in the operation and use of lawn mower

take effect

1. If the machine vibrates abnormally during operation, the engine must be stopped immediately and the operation must be suspended.

2. The machine must be operated with both hands, and it is forbidden to operate with one hand.

3. Never put your hands or feet near the rotating blades when the engine is running.

4. One side of the engine muffler should be outward to avoid scalding.

Correct mowing method

1. Because the blade turns left, the efficient working direction is to mow the grass from left to right.

2. The most effective mowing method is to mow weeds by two thirds of the blade diameter.

After surgery

1, wrap the blade after use, so as not to injure others or yourself by mistake.

2. If you don't need to clean the fuel tank for several days in a row, so as to avoid oil leakage and fire.

3. Before cleaning, maintenance and inspection, ensure that the blade stops completely.

4. Remove the spark plug wire to avoid accidental fire.

Please wait until the engine is completely cooled before storing.

6. Store the machine in a cool and dry place and keep it away from children.

7. Replenish the gearbox with lubricating oil every 25 hours or three and a half days to lubricate the internal and external pipelines.

8. Clean the air filter and spark plug every 50 hours or 8 days.

9. Clean the muffler and drum every 100 hour or 15 days.

10, when not used for a long time, butter the blade to prevent the blade from rusting.

Maintenance of lawn machine

The maintenance of lawn mower is much more important than the maintenance after the lawn mower is damaged. Maintenance is the most basic work for any machine to get the best performance. It can greatly reduce the premature wear and bite of parts, reduce unpredictable machine damage and expensive maintenance costs, and prolong the service life of lawn mower. The maintenance of lawn mower can be divided into three parts. The first is routine maintenance, mainly routine inspection and cleaning. The second is regular maintenance, including replacing all kinds of oil products, replacing all kinds of filter elements, checking all adjustments, such as braking, testing all functions of the machine and making necessary maintenance. The last part is maintenance, including replacing damaged parts, checking all adjustments, such as braking, testing all functions of the machine, and making necessary maintenance, cleaning and lubricating the machine.

Daily maintenance of lawn machine

1, flushing

Rinse the machine with medium-pressure and medium-flow water. Washing with high-pressure water will make water and impurities penetrate into the bearing through the seal. Try to avoid washing hot machines with cold water. Because quenching will form a vacuum cavity in the bearing, it will suck water in.

Do not flush electrical components, radiators, oil coolers, high-temperature engines and exhaust devices with water. When cleaning the machine, check whether the parts are damaged or loose. At the same time, check whether there is leakage of hydraulic oil and engine oil, and the degree of wear and damage of hydraulic pipeline.

Step 2 purify

Clean the screen, radiator and oil cooler with low-pressure compressed air of about 50Psi(3.4bar). Blow clean the instrument panel and electrical components. Blow out the tool box and spare parts box. For the engine area, first clean the engine box by hand, and then purge it with compressed air. Check the radiator hose, fuel pipe and filter for leakage and damage. Remove the debris from the radiator and cooler every day, and once every hour if the working conditions are too dusty and dirty. Check the condition and tension of all exposed belts, adjust them if necessary, and remove and clean the air pre-filter.

Unless they have received appropriate training, lawn mowers are not allowed to disassemble and clean the air filter without authorization. Because if the air filter is cleaned and maintained too much, it may cause unnecessary seal damage, and improper installation will also lead to impurities entering the engine.

3. Safety interlock test

Most lawn machinery has some safety interlocking devices to protect the operator and the machine itself from injury. The test of these safety interlocks should be completed by mowers, who should be responsible for the safety of themselves and the people around them. Generally speaking, when starting the machine, the drive pedal should be in neutral and the mower unit is not engaged, otherwise it cannot be started. To start the machine, the handbrake must be disengaged, and the operator must sit in the chair, otherwise the engine will stall.

In addition, different machines will have some different interlocking devices, please refer to the operation manual. Please note that if the machine fails these interlock tests, it cannot be used. In the recommendation table for regular maintenance, it is required to replace all safety interlock switches every two years or after a certain period of operation.

Step 4 bribe

After each cleaning of the machine, it is required to add a little butter to the hob or rotary cutter head. Please refer to the operation manual for the location of the grease nipple and the type of grease. When adding grease, rotate the drum, hob or rotary knife by hand, which is helpful to evenly distribute grease and check the contact and operation of bearings.

General lubricating points must be lubricated regularly with No.2 general lithium salt grease. If the machine is used under normal conditions, lubricate the bearings and bushings every 50 hours. When the working conditions are particularly dusty and extremely dirty, bearings and bushings must be lubricated every day. Dirty operating environment may cause dust to enter bearings and bushings, thus increasing wear. Lubricate bearings and bushings immediately after each flushing, regardless of the specified time interval.

5, anti-corrosion and anti-clogging

Biting threads and parts is a headache. After each cleaning, exposed threads and pivots should be sprayed with lubricant. For those coastal courses, due to the high salt content of sea breeze and water, it is easy to cause premature corrosion of the machine, so it is best to blow dry the exposed parts such as the knife set after each cleaning, and then spray rust inhibitors (note that some rust inhibitors may damage the lawn, so please choose carefully or clean them before mowing). ?

6, liquid level check

Generally, four levels should be checked, namely, oil level, hydraulic oil level, coolant level and fuel level.
