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.
• Do not move the power cutter with the blade rotating.
• Make sure that no pipes or electrical cables are routed in the
area to be cut.
WARNING! A safe distance from the power
cutter is 15 metres. You are responsible that
animals and onlookers are not in the working
area. Do not start to work with the power
cutter before the working area is clear and
you have a firm foothold.
• Start cutting with the engine at full throttle.
• Always hold the power cutter firmly, with both hands. Hold
the machine so that the thumb and fingers grip around the
handle.
Cutting
Only use the machine in areas with good
ventilation. Neglect can result in serious
injury or death. Carbon monoxide in the
exhaust fumes causes suffocation.

SAFETY INSTRUCTIONS
!
Over exposure to vibrations can 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.
!
Cutting technique
The technique described below is of a general character.
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 push the
blade in.
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!
Do not lean the blade to the side, this can
cause the blade to jam or break with personal
injury as a consequence.
Kickback
If the sector of the blade illustrated below is used for cutting the
blade can start to climbing and kickback the power cutter
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
throttle.
6.Take care when inserting
the blade in an existing
cut.
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.
!
WARNING!
Kickback can occur very suddenly and with
great force. If the following directives are not
followed, it can result in serious or even fatal
injury.
English – 9
SAFETY INSTRUCTIONS
!
WARNING!
If the speed is higher than that stated then the
unit must be adjusted by an authorised
service workshop before it is used.
Pull in
Pull in occurs when the lower part of the blade is suddenly
stopped or when the cut closes. (To avoid this see the section
”
How to avoid kickback
” and
”Pinching/rotation”
below).
Pinching/rotation
Pinching occurs when the cut closes. The power cutter can be
drawn suddenly and powerfully downwards.
How to avoid pinching
Support the work piece in
such a way that the cut
remains open during the
cutting operation and when
the cut is finished.
Check the engine speed
Use a tachometer regularly
to check the engine speed
when the cutter is running at
working temperature and at
full throttle without a load.
The maximum engine speed
is stated on the machine.
Care and storage
General
Partner’s power cutters are robust and durable. However, as
they are used for high speed operations all servicing should be
carried out on time and as specified, so that the power cutter
always works effectively and safely.
Read this Operator’s Manual to determine which service
routines you can carry out and ensure that all other service
work is carried out by an authorised service workshop.
Power Cutter
Always handle the power cutter with care and store it in the
wooden carrying case in which it is delivered.
Blade
• Inspect new blades for
transport or storage
damage.
!
WARNING!
Cool a diamond blade continously with water
to prevent overheating, which can cause the
blade to break and pieces being thrown off
resulting in injury and damage.
Diamond blades
Diamond blades are manufactured from industrial diamonds
held together by a bonding agent.
Low cost per
cutting operation. Constant
cutting depth.
Less dust.
Increases the
blades service
life.
All brickwork,
reinforced
concrete and
other composite
materials. NOT
recommended for
metal.
DIAMOND BLADES
General char- Material Water cooling
acteristics
Water cooling
!
WARNING! Water cooling, which is used when
cutting concrete, cools the cutting blade and
increases its service life as well as reduce
dust formation. Among the disadvantages are
difficulties at very low temperatures, the risk
of damaging the floor and other sections of
the building and risk for slippage.
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.
