THE POWER CUTTER’S SAFETY
EQUIPMENT
This section describes the power cutter’s safety equipment, its
function and how checks and maintenance are carried out to
ensure that it operates correctly. (See the chapter
to locate where this equipment is positioned on your
what“
power cutter.)
WARNING! Never use a power cutter with
!
defective safety equipment. Follow the
control, maintenance and service instructions
described in this manual.
1 Anti-vibration
system
Your power cutter is equipped
with an anti-vibration system.
This is designed to give as low
vibration levels and
comfortable usage as possible.

• LEG PROTECTION (TO
PROTECT AGAINST
SPARKS AND CUTTING
FRAGMENTS)
• ANTI-SLIP BOOTS WITH
STEEL TOE CAPS
The power cutter’s antivibration system reduces the
transfer of vibration between
the engine/cutting equipment
and the cutting trolley. The
engine body including the
cutting equipment is
suspended in a handle system
via anti-vibration elements.

4 Throttle lock
The throttle lock is designed
to prevent accidental operation of the throttle control.
When you press the lock (A)
(i.e. when you grasp the
handle) it releases the throttle
trigger (B). When you release
the handle the throttle trigger
and the throttle lock both
move back to their original
positions. This movement is
controlled by two independent
return springs. This arrangement means that the throttle
control is automatically locked
at the idle setting when you
release the handle.

damage. A damaged cutting blade can cause
personal injury.
WARNING! Never use a power cutter with
defective safety equipment. The power
cutter’s safety equipment should be checked
and maintained as described in this
Operator’s Manual. If your power cutter does
not meet any of these controls you should
contact your service workshop.
2 Press the throttle lock and
make sure it returns to its
original position when you
release it.
3 Check that the throttle
control and throttle lock
move freely and that the
return springs work
properly.
4 Start the power cutter and
apply full throttle. Release
the throttle control and
check that the blade stops
and remains stationary. If
the blade rotates when
the throttle is on idle

• Never start the machine:
• Store the power cutter and fuel so that any leakage or fumes
do not risk coming into contact with sparks or naked flames.
For example, electric machines, electric motors, electrical
switches/power switches, heaters or the like.
• When storing fuel, approved containers intended for this
purpose must be used.
• When storing the power cutter for long periods the fuel tank
must be emptied. Contact your local petrol station to find out
how to dispose of excess fuel.

GENERAL WORKING INSTRUCTIONS
This section takes up the basic safety precautions for working
with the power cutter. Follow these general working instructions,
but never use a machine without the possibility of calling for
help in the event of an accident.
Basic safety precautions
IMPORTANT INFORMATION! Never work with a power
cutter that is defective or incorrectly adjusted. Do not
work with a power cutter that is incomplete or where
assembly has not been carried out in a satisfactory
manner. Check that the cutting blade stops rotating
when the throttle is released. If you encounter a situation
where you are uncertain how to proceed you should ask
an expert.
Avoid all usage which you consider to be beyond your
capability.
• Check that no one is in the immediate vicinity when the
machine is started or while working with the machine to
ensure that people, animals or other things cannot affect your
control of the power cutter.
• Avoid usage in unfavourable weather conditions, for example,
thick fog, heavy rain, strong winds or extreme cold, etc. To
work in bad weather conditions is tiring and can create
dangerous circumstances, e.g. slippery surfaces.
• Never start to work with the power cutter before the working
area is clear and you have a firm foothold. Look out for any
obstacles with unexpected movement. Ensure when cutting
that no material can become loose and fall, causing operating
injury.Take great care when working on sloping ground.
• Make sure clothing and parts of the body do not come into
contact with the cutting blade when the engine is started.
• Maintain a safe distance from the cutting blade when the
engine is running.
• The blade guard should always be fitted when the engine is
running.
• Ensure that the working area is sufficiently illuminated to
create a safe working environment.
• Check the cutting area for buried cables and wires.
• Use a Husqvarna fuel can with an anti-spill device.
WARNING! Fuel and fuel fumes are highly
flammable. Think of the risks of fire, explo-
!
sion and breathing in fumes. Stop the engine
before refuelling. Do not overfill with fuel.
Mop up any spills on the ground or the
machine. If you spill fuel on yourself or your
clothes, change your clothes. Move the
machine at least 3 metres from the refuelling
site before starting.
Only use the machine in areas with good
ventilation. Neglect can result in serious
!
injury or death.

Cutting technique
The technique described below is of a general character. Check
information for each blade regarding individual cutting characteristics. (For example, a diamond blade requires less feeding
pressure than a abrasive blade).
1.Support the work piece in
such away that you can
predict what will happen
and so it will not pinch.
2.Always cut at full throttle.
3.Start cutting gently, do
not force or squeeze the
blade in.
result in blood-vessel or nerve injury to
persons suffering with blood circulation
problems. Seek medical attention if you
experience physical symptoms that can be
related to over exposure to vibrations.
Examples of such symptoms are numbness,
lack of feeling, “tickling“, “pricking“, pain lack
of or a reduction in normal strength, changes
in the colour of the skin or its surfaces. These
symptoms normally appear in the fingers,
hands or wrists.

for petrol-driven power cutters and when
!
Sharpening diamond blades
Blades can become dull when the wrong feeding pressure is
used or when cutting some materials such as heavily reinforced
concrete. To force a dull blade results in overheating and finally
the loss of segments (part of the blade).
Sharpen against a soft material such as sandstone or haydite
brick.
Blade vibration
The blade can become out of shape (not round) and vibrate if a
too high feeding pressure is used or if the blade is pressed into
the work piece.
A lower feeding pressure ought to stop the vibration. Otherwise
replace the cutting blade.
cutting concrete, cools the cutting blade and
increases its service life as well as reduce
dust formation (see the section ”
”). Among the disadvantages are
blades
difficulties at very low temperatures, the risk
of damaging the floor and other sections of
the building and risk for slippage.
Abrasive
Kickback
4.Use a high blade speed.
5.Move the blade slowly
backwards and forwards.
6.Use a small part of the
blade’s cutting edge.
7.Only use the blade’s
cutting edge when
cutting.
8.Cut with the blade fully
vertical – at right angles
to the work piece.
WARNING!
Under all circumstances avoid cutting using

the side of the blade; it will almost certainly
be damaged, break and can cause immense
damage. Only use the cutting section.
WARNING!
Kickback can occur very suddenly and with

upwards and backwards towards the user with immense force.
How to avoid kickback
1.Never cut with the
segment illustrated in the
diagram.
2.Keep a good balance and
a firm foothold.
3.Use both hands and take
a firm grip with the thumb
and fingers around the
handle.
4.Keep the work piece at a
comfortable distance.
5.Use the cutter at full

followed, it can result in serious or even fatal
injury.

WARNING!
Do not lean the blade to the side, this can
cause the blade to jam or break with personal
injury as a consequence.
7.Never cut above shoulder
height.
8.Be alert to movement of
the work piece or anything
else that can occur, which
could cause the cut to
close and pinch the blade.
