GENERAL SAFETY PRECAUTIONS
Sharpening grass knifes and grass
blades
• See the cutting attachment packaging for correct
sharpening instructions. Sharpen blades and knifes
using a single-cut flat file.
• Sharpen all edges equally to maintain the balance of
the blade.
WARNING! Always discard a blade that is
!
bent, twisted, cracked, broken or
damaged in any other way. Never attempt
to straighten a twisted blade so that it
can be reused. Only use original blades
of the specified type.
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. This will make the line
tougher so that it lasts longer.
