result in electrical shock. Do not use a
machine with a damaged spark plug cap.
(Fig. 45 )
To start a warm engine
1. Set the stop switch to the start position.
2. Press the air purge 10 times. The bulb must not be
completely filled.(Fig. 46 )
3. Return the choke control to the run position.
4. Pull the cord quickly and powerfully. Repeat until the
engine starts.
To stop
• Switch off the ignition to stop the engine.(Fig. 47 )
To operate the grass trimmer
CAUTION: Make sure that you slow the
engine to idle speed after each operation. A
long period at full throttle without a load on
the engine can cause damage to the engine.
Note: Clean the cover of the trimmer head when you
attach a new trimmer line to prevent vibrations. Examine
other parts of the trimmer head and clean if it is
necessary.
General work instructions
WARNING: Be careful when you cut a tree
that is in tension. It can spring back to its
normal position before or after the cut and
hit you or the product, and cause injury.
• Clear an open space at one end of the work area,
and start the work from there.
• Move in a regular pattern across the work area.(Fig.
48 )
• Move the product fully to the left and right, to clear a
width of 4–5 m (13-16 ft) on each turn.
• Clear a length of 75 m (250 ft) before you turn and
go back. Move the fuel can along with you as you
continue.
• Move in a direction where you do not go across
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.
