SAFETY INSTRUCTIONS
Cutting equipment Sharpening the
grass blade
• See the cutting
equipment’s packaging for
correct filing instructions.
• The blades are sharpened
using a single cut flat file.
• Sharpen all edges equally
to maintain the balance of
the blade.
Trimmer head
• Only use a trimmer head
and trimmer cord that is
recommended. 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
cutting equipment we
recommend! See chapter
“Technical data“.
!
WARNING!
Always stop the engine before starting
work on any part of the cutting equipment.
This continues to rotate even after the
throttle has been released. Ensure that the
cutting equipment has stopped completely
and remove the cable from the spark plug
before you start to work on it.
IMPORTANT INFORMATION
Always ensure the trimmer cord is wound tightly
and evenly around the drum, otherwise harmful
vibrations will occur.
• Generally smaller machines require a small trimmer head
and vice versa. This is because when clearing using a cord
the engine must throw out the cord radially from the
trimmer head and also meet resistance from 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 the knife positioned 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 few days. This will make the line tougher and it will keep
longer.
Sharpening the
clearing blade
• See the cutting
equipment’s packaging for
correct filing instructions.
• A correctly sharpened
blade is a prerequisite for
working efficiently and to
avoid unnecessary wear to
the blade and clearing saw.
• Make sure that the blade is
well supported when you
use the file. Use a 5,5 mm
round file with a file
holder.
• The sharpening angle is
15°. Every other tooth is
sharpened to the right and
the intermediate tooth to
the left. When the blade
has been heavily pitted by
stones the upper side of
the teeth can, in
exceptional cases, need to
be dressed using a flat file.
In such cases this takes
place before sharpening
with the round file.
Dressing the top side must
be carried out equally for
all teeth.
• Adjust the setting. This
should be 1 mm.
IMPORTANT INFORMATION
The section describes how through correct mainte-
nance and through using the right type of cutting
equipment you can reduce the machine‘s tendency to
kickback, obtain maximum clearing capacity and
increase the service life of the cutting equipment.
• Only use the cutting and guard equipment we
recommend! See chapter “Technical data“.
• Refer to the instructions for the cutting
equipment for the correct winding of cord
and for the selection of the right cord diameter.
• Keep the blade’s teeht well and correctly
sharpened! Follow our recommendations. Also
refer to the instructions on the blade packaging.
• Maintain the correct setting. Follow our instruc-
tions and use the recommended filing gauge.
WARNING!
Incorrect cutting equipment or an
incorrectly sharpened blade increases
the risk of kickback.
