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

or do maintenance.

• Use head protection when you operate a product

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.

• 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.

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.
