a properly mounted guard, the built-in cutter
will automatically adjust the line to its proper
length. Overly long lines can overload the
engine, resulting in damage to the clutch
mechanism and nearby parts.
Trimming
• Hold the trimmer head just above the ground
at an angle. It is the end of the cord that does
the work. Let the cord work at its own pace.
Never press the cord into the area to be cut.
• The cord can easily remove grass and weeds
up against walls, fences, trees and borders,
however it can also damage sensitive bark on
trees and bushes, and damage fence posts.
• Reduce the risk of damaging plants by
shortening the cord to 10-12 cm and reducing
the engine speed.
Clearing
• The clearing technique removes all unwanted
vegetation. Keep the trimmer head just above
the ground and tilt it. Let the end of the cord
strike the ground around trees, posts, statues
and the like.
CAUTION: This technique increases the
wear on the cord.
• The cord wears quicker and must be fed
forward more often when working against
stones, brick, concrete, metal fences, etc., than
when coming into contact with trees and
wooden fences.
• When trimming and clearing you should use
less than full throttle so that the cord lasts
longer and to reduce the wear on the trimmer
head.
Cutting
• The trimmer is ideal for cutting grass that is
difficult to reach using a normal lawn mower.
Keep the cord parallel to the ground when
cutting. Avoid pressing the trimmer head
against the ground as this can ruin the lawn
and damage the tool.
• Do not allow the trimmer head to constantly
come into contact with the ground during
normal cutting. Constant contact of this type
can cause damage and wear to the trimmer
head.
Sweeping
• 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.
WARNING: Never cut, when visibility is
poor or in very high or low temperatures or in
freezing weather.
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
