Common faults and causes of brush cutters: maintenance and handling methods for brush cutters

Fault 6: The brush cutter has poor grass collection effect. The cause analysis and handling methods are as follows:

1. Long term use of grass collection bags without cleaning results in uncleanness and lack of breathability, leading to poor grass collection. Exclusion method: Clean the straw bag thoroughly.

2. If the grass outlet is not cleaned for a long time, it will be blocked by accumulated grass, resulting in poor grass drainage. Troubleshooting method: Clean the grass outlet thoroughly.

3. The blade is excessively worn, and the blade wings cannot effectively collect grass. Troubleshooting method: Replace the blade.

4. Engine wear, excessive power loss, and low blade rotation speed result in poor grass collection effect. Troubleshooting method: Repair or adjust the engine to achieve the rated speed.

Fault 7: The cause of engine smoke. The cause analysis and handling methods are as follows:

1. Black smoke: The reason for producing black smoke is that the mixture density of the intake combustion is too deep, with more fuel entering and less air entering. Exclusion method: Clean or update the air filter; If the fault is not resolved, the carburetor of the engine needs to be adjusted or cleaned.

2. Blue smoke: The cause of blue smoke is the participation of engine oil in combustion. Troubleshooting method: After discovering the fault, first check the oil dipstick to see if there is excessive oil; If excessive, drain the excess oil and run for another ten minutes; If the fault is still not resolved, the engine needs to be repaired.

3. White smoke: The reason for emitting white smoke is that water participates in combustion. Exclusion method: Low weather temperature is a normal phenomenon; If there is water in the fuel, replace it with a new anhydrous fuel.
