Sweeping
en
• The fan effect of the rotating cord can be
used for quick and easy clearing up. Hold
the cord parallel to and above the area to
be swept and move the tool to and fro.
• When cutting and sweeping you should use
full throttle to obtain the best results.

visibility is poor or in very high
or low temperatures or in freezing
weather.
WARNING: If the cutting tool or
deflector becomes clogged or
stuck, always turn off the engine
and make sure the cutting tool has
stopped before cleaning. Grass,
weeds, etc. should be cleaned
off the cutting tool at regular
intervals.
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 fi rm 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

OPERATION
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, fi rst 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 diffi cult to gain access, cut
the stems high up and let them fall. This will
reduce the risk of jamming.
