Check to ensure there is fuel in the tank, the spark plug is clean and functioning, and the air filter is not clogged. If issues persist, consult the user manual or contact a professional for servicing.
Regular maintenance should be performed after every 25 hours of use. This includes checking the spark plug, cleaning the air filter, and inspecting the fuel filter.
Drain the fuel tank, clean the brushcutter thoroughly, and store it in a dry, cool place. It's also advisable to lubricate moving parts to prevent rust.
Locate the carburetor adjustment screws, typically marked as 'H' (high speed) and 'L' (low speed). Use a screwdriver to adjust these screws while the engine is running until optimal performance is achieved.
Excessive vibration can be caused by a misaligned or damaged cutting attachment. Check the attachment for damage and ensure it is properly secured. Consider balancing the cutting head if necessary.
It is not recommended to use the brushcutter in wet conditions as it can be hazardous and may damage the engine. Always ensure the tool is dry before use.
Always wear protective gear such as safety glasses, gloves, and hearing protection. Keep bystanders at a safe distance, and never operate the tool above shoulder height.
