remove the cut material while the engine is
running or the cutting equipment is rotating,
as this can result in serious injury. Stop the
engine and cutting equipment before you
remove material that has wound around the
blade as otherwise there is a risk of injury.
The bevel gear can get hot during use and
may remain so for a while afterwards. You
could get burnt if you touch it.
WARNING: Sometimes branches or
grass get caught between the guard and
cutting attachment. Always stop the engine
before cleaning.
Check before starting
• Check the blade to ensure that no cracks have
formed at the bottom of the teeth or by the
centre hole. Discard a blade if cracks are
found.
• Check that the support flange is not cracked
due to fatigue or due to being tightened too
much. Discard the support flange if it is
cracked.
• Ensure the locking nut has not lost its captive
force. The tightening torque of the locking nut
should be 25 Nm.
• Check that the blade guard is not damaged or
cracked. Replace the blade guard if it is
cracked.
WARNING: Never use the machine
without a guard or with a defective guard.
Never use the machine without the
transmission shaft.
Forestry clearing
• 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.
Grass clearing using a grass blade
• Grass blades and grass cutters 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.
• If the blade is angled to the left when clearing
grass, the grass will collect in a line, which
makes it easier to collect, e.g. by raking.
• Try to work rhythmically. Stand firmly with
your feet apart. Move forward after the return
stroke and stand firmly again.
• Let the support cup rest lightly against the
ground. It is used to protect the blade from
hitting the ground.
• Reduce the risk of material wrapping around
the blade by following these instructions:
1. Always work at full throttle.
2. Avoid the previously cut material during the
return stroke.
• Stop the engine, unclip the harness and place
the machine on the ground before you start to
collect the cut material.
Grass trimming with a trimmer head
CAUTION: Do not work with mowing
line longer than the intended diameter. With
a properly mounted guard, the built-in cutter
will automatically adjust the line to its proper
length. Overly long lines can overload the
