Maintenance
• Use a correct length of the grass trimmer line. A long
grass trimmer line uses more engine power than a
short grass trimmer line.
• Make sure that the cutter on the cutting attachment
guard is not damaged.
• Soak the grass trimmer line in water for 2 days
before you attach the grass trimmer line to the
product. This increases the life of the grass trimmer
line.
• Refer to the instructions for the cutting attachment to
use the correct procedure to load the cord and the
correct cord diameter.
