The correct fuel mixture for the Husqvarna 535RJ Brushcutter is 50:1, meaning 50 parts unleaded gasoline to 1 part two-stroke engine oil.
To replace the trimmer line, first turn off the engine and disconnect the spark plug. Remove the trimmer head by unscrewing it, then follow the instructions in the user manual to wind the new line onto the spool and reattach the head.
If the brushcutter won't start, check the fuel level, ensure the spark plug is clean and properly connected, and inspect the air filter for clogs. If the issue persists, consult the user manual or contact a service professional.
The air filter should be checked and cleaned after every 25 hours of use. If you operate the brushcutter in dusty conditions, clean the filter more frequently.
Regular maintenance includes checking and cleaning the air filter every 25 hours, inspecting the spark plug every 100 hours, and lubricating the gear housing and drive shaft as needed. Refer to the user manual for detailed intervals and procedures.
To store the brushcutter, clean it thoroughly, empty the fuel tank, and run the engine until it stops to clear the carburetor. Store it in a dry, well-ventilated area away from direct sunlight or extreme temperatures.
The Husqvarna 535RJ Brushcutter is compatible with grass blades, brush knives, and saw blades. Always ensure the blade is appropriate for the task and fitted securely.
To adjust the idle speed, locate the idle adjustment screw on the carburetor. Turn the screw clockwise to increase idle speed or counterclockwise to decrease it, ensuring the engine runs smoothly without the cutting attachment moving.
Wear protective gear including safety glasses, gloves, long pants, and sturdy footwear. Ensure the area is clear of people and pets, and be aware of potential hazards such as rocks and debris.
Check that the cutting attachment is balanced and securely attached. Inspect the drive shaft and clutch for wear or damage. If vibrations persist, consult the user manual or contact a qualified technician.
