To start the Husqvarna 525L Trimmer, ensure the stop switch is in the "on" position. Prime the engine by pressing the air purge bulb 5-10 times until fuel is visible. Set the choke lever to the choke position. Pull the starter handle until the engine fires, then set the choke to the run position and pull the starter again until the engine starts.
The Husqvarna 525L Trimmer requires a fuel mix of 50:1, which means 2.6 ounces of 2-stroke oil per gallon of unleaded gasoline. Use high-quality 2-stroke oil and fresh, unleaded gasoline with a minimum octane rating of 89.
Clean the air filter of the Husqvarna 525L Trimmer after every 5 hours of operation or more frequently in dusty conditions. Remove the air filter cover, take out the filter, and clean it with warm soapy water. Allow it to dry completely before reinstalling.
If the trimmer line is not advancing, check for the following: Ensure the line is not tangled or welded inside the trimmer head. Verify that the line is wound correctly and that the spool is not damaged. Replace the line if it is too short or worn out.
To replace the trimmer line on the Husqvarna 525L, remove the trimmer head by unscrewing the cap. Take out the spool and remove any remaining old line. Cut two lengths of line about 10 feet each, insert them into the spool, and wind them tightly in the direction indicated. Reassemble the head.
If the engine runs roughly or stalls, check the fuel quality and ensure the fuel mixture is correct. Inspect the air filter for dirt and clean it if necessary. Examine the spark plug for wear or damage and replace it if needed. Adjust the carburetor settings as per the user manual.
To adjust the idle speed on the Husqvarna 525L Trimmer, locate the idle speed screw near the carburetor. Turn the screw clockwise to increase the idle speed or counterclockwise to decrease it. Adjust until the engine idles smoothly without the cutting attachment moving.
After each use, clean the trimmer by removing grass and debris from the cutting attachment, air vents, and engine. Check for loose screws or parts and tighten them if necessary. Inspect the guard and trimmer head for damage and replace if needed.
To store the Husqvarna 525L Trimmer for the off-season, empty the fuel tank and run the engine until it stops. Clean the trimmer thoroughly and check for any need for repairs. Store it in a dry, well-ventilated area away from direct sunlight.
For the Husqvarna 525L Trimmer's gearcase, use a high-quality grease or lubricant specifically designed for trimmer gearcases. Check your user manual for recommended brands and specifications. Apply the lubricant according to the maintenance schedule.
