General working instructions

IMPORTANT!
This section describes the basic safety precautions for
working with brush cutters and trimmers.
If you encounter a situation where you are uncertain
how to proceed you should ask an expert. Contact your
dealer or your service workshop.
Avoid all usage which you consider to be beyond your
capability.
You must understand the difference between forestry
clearing, grass clearing and grass trimming before use.
Basic safety rules
1 Look around you:
• To ensure that people, animals or other things cannot
affect your control of the machine.
• To ensure that people, animals, etc., do not come into
contact with the cutting attachment or loose objects
that are thrown out by the cutting attachment.
• CAUTION! Do not use the machine unless you are
able to call for help in the event of an accident.
2 Inspect the working area. Remove all loose objects,
such as stones, broken glass, nails, steel wire, string,
etc. that could be thrown out or become wrapped
around the cutting attachment.
3 Do not use the machine in bad weather, such as dense
fog, heavy rain, strong wind, intense cold, etc. Working in
bad weather is tiring and often brings added risks, such
as icy ground, unpredictable felling direction, etc.
4 Make sure you can move and stand safely. Check the area
around you for possible obstacles (roots, rocks, branches,
ditches, etc.) in case you have to move suddenly. Take great
care when working on sloping ground.
5 Always carry this backpack type blower in its shoulder
harness while operating.
6 Keep a good balance and a firm foothold.
7 Always hold the machine with both hands.
8 Keep the cutting attachment below waist level.
9 Switch off the engine before moving to another area.
Fit the transport guard before carrying or transporting
the equipment any distance.

WORKING TECHNIQUES

10 Never put the machine down with the engine running
unless you have it in clear sight.
WARNING! Neither the operator of the
!
machine nor anyone else may attempt to
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 shaft 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! Watch out for thrown objects.
!
Always wear approved eye protection.
Never lean over the cutting attachment
guard. Stones, rubbish, etc. can be thrown
up into the eyes causing blindness or
serious injury.
Keep unauthorised persons at a distance.
Children, animals, onlookers and helpers
should be kept outside the safety zone of
15 metres. Stop the machine immediately
if anyone approaches. Never swing the
machine around without first checking
behind you to make sure no-one is within
the safety zone.
Basic working techniques
Always slow the engine to idle speed after each working
operation. Long periods at full throttle without any load on
the engine can lead to serious engine damage.
WARNING! Sometimes branches or
!
grass get caught between the guard and
cutting attachment. Always stop the
engine before cleaning.
WARNING! Machines fitted with saw
!
blades or grass blades can be thrown
violently to the side when the blade comes
into contact with a fixed object. This is
called blade thrust. A blade thrust can be
violent enough to cause the machine and/
or operator to be propelled in any
direction, and possibly lose control of the
machine. Blade thrust can occur without
warning if the machine snags, stalls or
binds. Blade thrust is more likely to occur
in areas where it is difficult to see the
material being cut.
Avoid cutting with the area of the blade
between the 12 o'clock and 3 o'clock
positions. Because of the speed of
rotation of the blade, blade thrust can
occur if you attempt to cut thick stems
with this area of the blade.
