What are the situations in which the brush cutter needs to be replaced?

The situations in which brush cutters need to be replaced mainly include:

‌Blade wear or damage‌: The blade is the core component of the brush cutter. If the blade is worn or damaged due to long-term use or impact, it will seriously affect the cutting efficiency of the brush cutter. At this time, a new blade needs to be replaced.

Air filter or air intake blockage‌: Air filter or air intake blockage will cause the power of the brush cutter to decrease, affecting its normal operation, so it is necessary to clean or replace the air filter in time‌.

Fuel system problem‌: If there is water in the fuel or there is a problem with the fuel system, such as too thin or too rich a mixture, it will also cause the brush cutter to have insufficient power or unstable operation. At this time, it is necessary to check and replace the relevant parts of the fuel system‌.

‌Spark plug problem‌: If the spark plug is aged, or damaged or the ignition time is incorrect, it will affect the starting and running performance of the brush cutter. New spark plugs need to be replaced in time‌.

Crankshaft, piston, and cylinder wear‌: If the crankshaft, piston, and cylinder are worn due to long-term use, it will cause the brush cutter to run unsteadily or the power to decrease. At this time, the relevant parts need to be replaced‌.

Guard is blocked‌: If the guard is not cleaned for a long time, it will to poor grass-collecting effect and affect the efficiency of the brush cutter. The guard should be cleaned or replaced regularly‌. ‌

Damage of throttle cable and flameout cable‌: Damage or improper installation of throttle cable and flameout cable will cause the brush cutter to fail to start or flame out normally. These parts need to be checked and replaced‌. ‌

Degradation of safety performance‌: If the safety performance of the brush cutter is reduced due to aging or damage of parts, such as problems with the brake system, protective devices, etc., the relevant parts should be repaired or replaced in time to ensure safe use‌. ‌

Regular inspection and maintenance are the keys to ensuring the normal operation of the brush cutter. When the brush cutter encounters any of the above situations, it should be inspected and replaced in time to maintain its good working condition and safety.
