Although a brush cutter is obviously not a vehicle, it is necessary to check and change the oil from time to time. Oil becomes dirty over time and must be removed from the engine. Otherwise, parts may be damaged. Fresh oil is golden or amber in color. However, after several months of use, it turns black. This is because heat, dirt and agitated air enter the crankcase and affect the oil. If the oil turns black, it must be removed from the engine as its coating and ability to protect engine components is compromised.

1. when to change the oil

A regular schedule should be established to check and change the oil. Experts suggest that the oil in the engine crankcase be changed every 50 hours of operation or at the end of each mowing season.

Additionally, if the brushcutter is new, the oil must be changed after the first five hours of operation.

Experts also recommend checking the oil every time the brush cutter is used. The most common adverse conditions for brush cutters include wet grass, high dust, high temperatures and rough or mountainous terrain, which can have a negative effect on the oil and may require more frequent oil changes.

2. check the oil level

The oil can be checked when the engine is cold. This condition provides the most accurate readings, since most of the oil is in the crankcase.

Use a level gauge to check the oil level and start the process. For the oil level to be correct, it must appear between the two holes of the level indicator. When changing the oil, be careful not to overfill the engine with oil. Overfilling can be as bad as using old oil. It is important to check the engine oil regularly.

Once the oil has been checked and it has been determined that it needs to be changed, the engine oil must be drained.

3. The oil draining procedure includes.

1) Run the brush cutter engine for 15 minutes to warm up the oil. This is essential to remove all dirty debris from the engine.

2) Stop the engine and disconnect the spark plug wires.

3) Empty the gasoline from the brush cutter or place a plastic bag over the fuel tank and screw the cap on. This is necessary to prevent leaks.

4) Insert the oil inlet pipe and pump the oil out of the engine.

5) Place the old oil in a container.

Now fill the engine with new oil. Fill the crankcase with oil and insert a level gauge into the tube. Take out the level gauge and check that there is the correct amount of oil in the oil tube. After checking that the oil level is correct, insert the level gauge and tighten the level gauge cap.

If fuel has been removed, fill the fuel tank with fresh fuel and reconnect the spark plug wires.
