SAFETY INSTRUCTIONS

Basic working techniques

Always slow the engine to idle speed after each working
operation. Long periods at full throttle without any load on
the engine can lead to serious engine damage.

Terms

Forestry clearing is a general term for cutting small trees,
during which each stem is cut individually. A saw blade is
used.

Brush cutting is a general term for clearing grass. Grass
blades and grass cutters are used for this purpose.

Grass trimming is a general term for light clearing, e.g.
around edges or around trees. A trimmer head or plastic
blades are used.

The ABC of clearing

Always use the correct equipment.

Make sure the equipment is well adjusted.

Follow the safety precautions.

Organise your work carefully.

Always use full throttle when starting to cut with the blade.

Always use sharp blades.

Avoid stones.

Control the felling direction (take advantage of the wind).

Working methods

Before you start clearing, check the clearing area, the
type of terrain, the slope of the ground, whether there are
stones, hollows etc.

Start at whichever end of the area is easiest, and clear an
open space from which to work.

Work systematically to and fro across the area, clearing a
width of around 4-5 m on each pass. This exploits the full
reach of the machine in both directions and gives the
operator a convenient and varied working area to work in.

Clear a strip around 75 m long. Move your fuel can as
work progresses.

On sloping ground you should work along the slope. It is
much easier to work along a slope than it is to work up and
down it.

You should plan the strip so that you avoid going over
ditches or other obstacles on the ground. You should also
orient the strip to take advantage of wind conditions, so
that cleared stems fall in the cleared area of the stand.

Forestry clearing using a saw blade

The risk of kickback increases with increasing stem size.
You should therefore avoid cutting with the area of the
blade between 12 o’clock and 3 o’clock.

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 advancing the blade.

!

WARNING! Sometimes branches or grass
get caught between the guard and cutting
attachment. Always stop the engine before
cleaning.

!

WARNING! Avoid cutting with the area of the
blade between the 12 o’clock and 3 o’clock
positions. Because of the speed of rotation
of the blade kickback can occur if you
attempt to cut thick stems with this area of
the blade.
