Trimmer head
WARNING: Always make sure the trimmer
line is wound tightly and evenly around the
drum to prevent harmful vibration.
(Fig. 30 )
Only use recommended trimmer heads and trimmer
lines.
Only use recommended cutting attachments.
Smaller machines requires small trimmer heads and
vice versa.
The length of the trimmer line is important. A longer
trimmer line requires greater engine power than a
shorter trimmer line of the same diameter.
Make sure that the cutter on the trimmer guard is
intact. This cuts the trimmer line to the correct
length.
Soak the trimmer line in water for a couple of days
before use to increase the life length.
Blades
Use the product with an approved blade. Do not use
a blade without proper installation of all required
parts. Make sure that the installation is done

with a blade.
A blade can cause injury when it spins after the
engine is stopped or the throttle trigger is released.
Make sure that the blade has completely stopped
rotating before maintenance.
Stop the engine before you do work on the cutting
attachment. Make sure the cutting attachment fully
stops. Disconnect the lead from the spark plug.
Keep the teeth of the blade correctly sharpened.
(Fig. 31 )
Do not use a damaged cutting attachment.
Attach the transport guard to the blade when you
transport or store the product.
Blade thrust
A blade thrust is a sudden movement of the product
to the side, forward or rearward. A blade thrust
occurs when the grass blade or saw blade hits an
object that cannot be cut. In areas where it is not
easy to see the material being cut the risk of blade
thrust increases.
When a blade thrust occurs, there is a risk that the
product or the operator moves out of position. A
blade that moves can hit bystanders and there is a
risk of injuries.
If a blade is bent, has cracks, is broken or damaged,
discard the blade.
Use a sharp blade. The risk of blade thrust increases
when a blade is not sharp.

ditches and obstacles more than necessary.
Move in a direction where the wind makes the cut
vegetation fall in the cleared area.(Fig. 49 )
Move along slopes, not up and down.
To forestry clear with a saw blade
1. The risk of blade thrust increases with increasing
stem size. therefore avoid cutting with the area of the
blade between 12 o'clock and 3 o'clock.(Fig. 50 )
2. To fell to the left, the bottom of the tree should be
pushed to the right. Tilt the blade and bring it
diagonally down to the right, exerting firm pressure.
At the same time push the stem using the blade
guard. Cut with the area of the blade between 3
o'clock and 5 o'clock. Apply full throttle before
advacing the blade. (Fig. 51 )
3. To fell to the right, the bottom of the tree should be
pushed to the left. Tilt the blade and bring it
diagonally up to the right. Cut with the areas of the
blade between 3 o'clock and 5 o'clock so that the
directions of rotations of the blade pushes the
bottom of the tree to the left.(Fig. 52 )
4. To fell a tree forwards, the bottom of the tree should
be pulled backwards. Pull the blade backwards with
a quick, firm movement. (Fig. 53 )
5. Large stems must be cut from two sides. First
determine which direction the stem will fall. Make the
first cut on the felling side. Then finish cutting the
stem from the other side. Adjust the cutting pressure
to match the size of the stem ant the hadness of the
wood. Small stems requre more pressure, while
large stems requre less pressure. (Fig. 54 )(Fig. 55 )
6. If the stems are tightly packed, adapt your walking
pace to suit.
7. If the blade jams in a stem, never jerk the machine
free. If you do this the blade, bevel gear, shaft or
handlebar may be damaged. Release the handles,
grip the shaft with both hands and gently pull the
machine free.
Brush cutting with a saw blade
To fell to the left, push the bottom of the tree to the right.
Cut down thin trees and brush.
Move the product from side to side.
Cut many trees in one movement.
For groups of thin trees:(Fig. 56 )
a) Cut the outer trees high up.
b) Cut the outer trees to the correct height.
c) Cut from the center. If you cannot get access to
the center, cut the outer trees high up and let
them fall. This decreases the risk that the saw
blade becomes blocked.
To clear grass with a grass blade
1. Grass blades and grass cutters must not be used on
woody stems.
2. A grass blade is used for all types of tall or coarse
grass.
3. The grass is cut down with a sideways, swinging
movement, where the movement from right-to-left is
the clearing stoke and the movement from left-to-
right is the return stoke. Let the left-hand side of the
blade (between 8 and 12 o'clock) do the cutting.
4. if the blade is angled to the left when clearing grass,
the grass will collect in a line, which makes it easier
to collect, e.g. by raking.

462 - 002 - 07.02.2018
5. Try to work rhythmically. Stand firmly with your feet
apart. Move forward after the return stoke and stand
firmly again.
6. Let the support cup rest lightly against the ground. It
is used to protect the blade from hitting the ground.
7. Reduce the risk of material wrapping around the
blade by always work at full throttle and avoid the
previously cut material during the return stoke.
8. Stop the engine, unclip the harness and place the
machine on the ground before you start to collect the
cut material.
To trim the grass
1. Hold the trimmer head immediately above the
ground at an angle.(Fig. 57 ) Do not push the grass
trimmer line into the grass.
2. Decrease the length of the grass trimmer line by
10-12 cm (4-4.75 in) and decrease engine speed to
decrease the risk of damage to plants.
3. Use 80 % throttle when you cut grass near objects.
(Fig. 58 )
To cut the grass
1. Make sure that the grass trimmer line is parallel to
the ground when you cut.(Fig. 59 )
2. Do not push the trimmer head to the ground. The
ground and the product can be damaged.
3. Do not let the trimmer head touch the ground
continuously, it can cause damage to the trimmer
head.
4. Use full throttle when you move the product from
side to side to cut grass. (Fig. 60 ) Make sure that
the grass trimmer line is parallel to the ground.
To sweep the grass
The airflow from the rotating trimmer line can be used to
remove cut grass from an area.
1. Hold the trimmer head and its trimmer line parallel to
the ground and above the ground.
2. Apply full throttle.
3. Move the trimmer head from side to side and sweep
the grass.
WARNING: Clean the trimmer head cover
each time you assemble new trimmer line to
prevent unbalance and vibrations in the
handles. Also do a check of the other parts
of the trimmer head and clean it if
necessary.
