3. For safe operation
instructions. Sharpen blades and cutters 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.
3. 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.
