Forestry clearing using a saw blade
• The risk of kickout increases with increasing
stem size. You should therefore avoid cutting
with the area of the blade between 12 o’clock
and 3 o’clock ( Fig.16 ).
• 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.
• 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.
Using the circular saw blade
WARNING: Circular saw blades are suitable
for thinning brush and cutting small trees up
to a diameter of 5 cm. Do not attempt to cut
trees with larger diameters, since the blade
may catch or jerk the clearing saw forward.
This may cause damage to the blade or loss of
control of the clearing saw which may result
in serious injury.
WARNING: A saw blade can only be used in
connection with the proper guard (see table
pag.38) a twin handle and double harness
with release mechanism.
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.
8. TRANSPORTING
