WORKING TECHNIQUES
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.
• 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 area of the blade between 3 o’clock and
5 o’clock so that the direction of rotation of the blade
pushes the bottom of the tree to the left.
• To fell a tree forwards, the bottom of the tree should be
pulled backwards. Pull the blade backwards with a quick,
firm movement.
• 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
!
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.
