GENERAL SAFETY PRECAUTIONS

Trimmer head

IMPORTANT!
Always ensure the trimmer cord is wound tightly and
evenly around the drum, otherwise the machine will
generate harmful vibration.
• 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 before use. This will make
the cord tougher so that it lasts longer.
