Trimmer head
IMPORTANT!
Always ensure the trimmer line is wound tightly and evenly around the drum, other- wise the machine will generate harmful vibration.
SOnly use the recommended cutting at- tachments. See the section on “Technical data”.
SSmaller machines generally require small trimmer heads and vice versa. This is be- cause when clearing using trimmer line the engine must throw out the trimmer line radially from the trimmer head and overcome the resistance of the grass being cleared.
SThe length of the trimmer line is also im- portant. A longer trimmer line requires greater engine power than a shorter
trimmer line of the same diameter.
SMake sure that the cutter on the trimmer
guard is intact. This is used to cut the trimmer line to the correct length.
STo increase the life of the trimmer line it can be soaked in water for a couple of days. This will make the line tougher so that it lasts longer.
