Husqvarna 520iLX Operator's Manual page 9

Trimmer head
• Always use the correct trimmer head, cutting
attachments and always use the recommended
trimmer line. Refer to
the assembly in the end of the Manual.
• Make sure that the cutter on the trimmer guard is not
damaged.
• Make sure that the trimmer line is wound tightly and
equally around the drum to prevent unusual
vibrations from the product. Different cord lengths
can result in vibrations that are not necessary. Tap
the trimmer head to get correct length on the cord.
To increase the life of the cord it can be soaked in water
for 2 days or more before assembly. This will make the
cord more resistant.
