To start the Husqvarna CSA850-28 Brushcutter, ensure the stop switch is in the 'ON' position, pump the primer bulb until it is full of fuel, set the choke lever to the start position, and pull the starter handle until the engine fires. Adjust the choke to 'RUN' once the engine is running smoothly.
Use a 50:1 fuel to oil ratio for the Husqvarna CSA850-28. This means mixing 2.6 ounces of two-stroke oil with one gallon of unleaded gasoline. Always use fresh, high-quality fuel.
To replace the trimmer line, first remove the spool cover by pressing the tabs on the sides. Take out the empty spool and wind the new line in the direction of the arrows on the spool. Secure the line ends in the notches before replacing the spool and cover.
Excessive vibration can be caused by a bent shaft, damaged cutting attachment, or loose parts. Inspect the brushcutter for any visible damage and tighten any loose components. Replace any damaged parts as necessary.
The air filter should be checked before each use and cleaned if necessary. For optimal performance, clean the air filter every 25 hours of operation or more frequently in dusty conditions.
If the engine won't start, check the fuel levels and ensure the choke is set correctly. Inspect the spark plug for fouling, and clean or replace it if necessary. Also, make sure the stop switch is in the 'ON' position.
Regular maintenance is key to ensuring the longevity of your CSA850-28. This includes cleaning the air filter, checking and replacing the spark plug annually, inspecting the fuel filter, and keeping the cutting attachments sharp and balanced.
Always wear protective gear including goggles, gloves, long pants, and sturdy shoes. Ensure the area is clear of bystanders and obstacles. Familiarize yourself with the controls and maintain a firm grip on the brushcutter during use.
Before storing, clean the brushcutter thoroughly and drain any fuel to prevent gumming. Store it in a dry, cool place away from direct sunlight. Consider lubricating metal parts to prevent rust.
Poor cutting performance can be due to a dull blade or incorrect line length. Sharpen or replace the blade as necessary and ensure the trimmer line is at the correct length. Check for any obstructions in the cutting head as well.
