WORKING TECHNIQUES
24 – English
•
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 side. Adjust the cutting pressure to
match the size of the stem and the hardness of the
wood. Small stems require more pressure, while large
stems require less pressure.
•
If the stems are tightly packed, adapt your walking
pace to suit.
•
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
•
Thin stems and brush are mown down. Work with a
sawing movement, swinging sideways.
•
Try to cut several stems in a single sawing movement.
•
With groups of hardwood stems, first clear around the
group. Start by cutting the stems high up around the
outside of the group to avoid jamming. Then cut the
stems to the required height. Now try to reach in with
the blade and cut from the centre of the group. If it is
still difficult to gain access, cut the stems high up and
let them fall. This will reduce the risk of jamming.
Grass clearing using a grass blade
•
Grass blades and grass knifes must not be used on
woody stems.
•
A grass blade is used for all types of tall or coarse
grass.
•
The grass is cut down with a sideways, swinging
movement, where the movement from right-to-left is
the clearing stroke and the movement from left-to-
right is the return stroke. Let the left-hand side of the
blade (between 8 and 12 o’clock) do the cutting.
