Trimmer head
Only use the recommended trimmer heads and 
trimmer cords. These have been tested by the 
manufacturer to suit a particular engine size. This is 
especially important when a fully automatic trimmer 
head is used. Only use the recommended cutting 
attachment. See the chapter on Technical data.
Smaller machines generally require small trimmer 
heads and vice versa. This is because when clearing 
using a cord the engine must throw out the cord 
radially from the trimmer head and overcome the 
resistance of the grass being cleared.
The length of the cord is also important. A longer cord 
requires greater engine power than a shorter cord of 
the same diameter.
Make sure that the cutter on the trimmer guard is 
intact. This is used to cut the cord to the correct length.
To increase the life of the cord it can be soaked in 
water for a couple of days. This will make the line 
tougher so that it lasts longer.
IMPORTANT!
Always ensure the trimmer cord is wound tightly and 
evenly around the drum, otherwise the machine will 
generate harmful vibration.
