WARNING!
Read the operating manual carefully before using the Guarda Edge Powercutter.
For Operating Techniques,refer to page 9.
WARNING!
The Guarda Edge Powercutter must always be used in conjunction with a vacuum system that
can capture the slurry that the saw produces.
WARNING!
The slurry produced while cutting can be heavy. Only use a 5 metre vacuum hose between the
Guarda Edge Powercutter and Vacuum or Slurry Interceptor.
WARNING!
The Guarda Edge Powercutter uses water to cool the exhaust gases. To prevent water entering
the muffler always:
1 - have the vacuum system on when the water is on,
2 - always stand the machine in the vertical position on its feet when the water is on and the
machine is not being operated.
3- Run the vacuum system for several minutes at completion of job or move it to clear vacuum
lines of any water.

WARNING!
The Guarda Edge Powercutter uses water to cool the exhaust gases. To prevent water
entering the mufer always:
1 have the vacuum system on when the water is on,
2 always stand the Edge Powercutter in the vertical position on its feet when the water is
on and the machine is not being operated.
3 Run the vacuum system for several minutes at completion of job or move it to clear
vacuum lines of any water.
WARNING!
Use only with water and vacuum on full. Refer to start and stop instructions on page 17.
7.5 metre vacuum hose between the
For setup and connection options refer to page 15 and 16
For system start and stop sequence refer to page 17
!
WARNING!
The exhaust fumes are cooled by a combination of water and air ow around the mufer
port. Slurry blockages can impede the ow of air and water. This will stop the air ow which
will prevent exhaust cooling. As a result the hoses will get hot and may melt. Always ensure
that the water supply, and the saws main tap are turned on full and the vacuum is on before
cutting, to minimise the chance of slurry blockages. The main indicator of a blockage will be
slurry running out from the front of the blade guard. If this occurs immediately stop the saw
and clear the blockage to ensure heat buildup from the exhaust does not melt the hoses. If
blockage occurs refer to page 23 for instructions to clear it.
WARNING!
If vacuum automatically shuts off, the exhaust fumes produced by the saw will no longer be
cooled and the hose will melt within 1 minute of operation. If vacuum shuts off, slurry will
ow from the front of the blade guard. In this case ensure the Edge Powercutter is turned
off immediately and vacuum is emptied.
!
!
WARNING!
Only use diamond blades with a steel core blank. Never use abrasive blades.
!
WARNING!
The slurry produced while cutting can be heavy. Ensure you read and follow “set up and
connection options” on pages 15 and 16

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 before the engine
is running.
Ensure that the working area is sufficiently illuminated to
create a safe working environment.
Be aware that some working positions may create greater stress
Check the cutting area for buried cables and wires.
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
The exhaust contains poisonous fumes
such as carbon monoxide.Neglect can
result in serious injury or death. Always place
the vacuum outdoors to vent the fumes
Min 3 m

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.
Water cooling
Cutting technique
The technique described below is of a general character. Check
information for each blade regarding individual cutting characte-
ristics.
b) cut with the guard close
to the workpiece.
c) choose a blade that
doesn't protrude through
the workpiece or place a
cover over the place the
blade will protrude.
1.Support the work piece in
such away that you can
predict what will happen
and so it will not pinch.
2.Start cutting gently, do
not force or squeeze the
blade in.
3.Use a high blade speed.
4.Only use the blade’s
cutting edge when
cutting.
5.Always cut with the blade
at right angles to the work
piece.
6.To minimise dust and
slurry always:
a) cut with the bottom of
the guard against the
workpiece.
WARNING! Water cooling, which should only
be used on petrol-driven power cutters,cools
the cutting blade and increases its service life
as well as reducing dust formation. Among
the disadvantages are difficulties at very low
temperatures and damaging the floor and
other sections of the building and risk for
slippage.
WARNING!
Under all circumstances avoid cutting using
the side of the blade; it will almost certainly
be damaged, break and can cause damage &
personal injury. Only use the cutting section.
WARNING!
Do not lean the blade to the side, this can
cause the blade to jam or break with personal
injury as a consequence.
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, silica 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.
Kickback
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.
If the sector of the blade illustrated below is used for cutting the
blade can start to climb and kickback the power cutter
upwards and backwards towards the user with immense force.
How to avoid kickback
1.Never cut with the
segment highlighted in the
diagram at the top right.
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.

SAFETY INSTRUCTIONS
WARNING!
If the speed is higher than the maximum
speed 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 speed of the
drive shaft
Use a tachometer regularly to
check the speed of the drive
shaft when the cutter is
running at working tempera-
ture and at full throttle without
a load. The maximum speed
is stated on the unit.
Care and storage
General
Guarda’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 with the
blade removed.
Blades
All blades should be
removed from the cutter
after use and stored
carefully.
Never use abrasive blades
Blades must be stored on
a firm, level surface. If
blades are supplied with a
backing pad then a spacer
should be used to keep
them flat.
Avoid moisture and
temperature extremes.
Remove the blades before
the power cutter is moved
or transported.
Inspect new blades for
transport or storage
damage.

OPERATING TECHNIQUE TO MINIMISE DUST AND SLURRY
The Edge powercutter uses water and vacuum to control slurry,
dust and exhaust fumes. Make sure you follow the set up
procedures outlined on page 15 and 16.
The blade guard has 2 water supply jets.
One water jet sprays constantly on the base of the blade guard
when the water supply is turned on. This helps to create a uid
mixture of cutting residue to minimise vacuum line clogging.
This also ensures there is adequate cooling for the exhaust
gases.
The second water jet is
directly onto the cutting
blade. Water volume can be
controlled by the tap on the
saw front handle.
The water jets are designed and positioned to supply water
efciently onto the blade so that when the blade rotates the
water feeds onto the cutting area of the blade.
1 Before cutting. Turn on the water supply to the blade.
Adjust water amount. Rev the engine and make sure an
adequate of water is coming off the blade. A light spray is
sufcient.
3. During cutting.
Keep the blade guard
against the cutting
surface. To help
achieve this the blade
guard is designed
to rotate within the
vacuum shroud so that
the orientation of the
saw can change easily
while keeping the
guard against the wall.
TAP
2 Starting the cut.
Ensure that the bottom
of the guard is close to
the cutting surface and
move the blade into the
material being cut while
keeping the bottom of
the blade guard against
the cutting surface.
WARNING!
Always ensure that the water supply,
and the saws main tap are turned
on full and the vacuum is on before
cutting, to minimise the chance of
slurry blockages. The main indicator
of a blockage will be slurry running out
from the front of the blade guard. If
this occurs immediately stop the saw
and clear the blockage to ensure heat
buildup from the exhaust does not melt
the hoses.

MAINTENANCE
Carburetor
Your Guarda product has been designed and manufactured to
specifications that reduce harmful emissions.
After your unit has been run for 8-10 tanks of fuel the engine has
broken in. To ensure that your unit is at peak performance and
producing the least amount of harmful emissions after break in,
have your authorized servicing dealer, with a revolution counter
at his disposal, check your carburetor for optimum operating
conditions.
Carburetor
T
Contact your servicing dealer, if the idle speed
setting cannot be adjusted so that the blade
stops. Do not use the power cutter until it has
been properly adjusted or repaired.
Final setting of the idling speed T
Adjust the idling speed with the screw T. If it is necessary to re-
adjust, first turn the idle speed adjusting screw T clockwise until
the blade starts to rotate. Then turn counter clockwise until the
blade stops. When correctly adjusted the saw will run in any
orientation.There should also be a good margin between the idle
speed setting and the engine speed required to start the blade
rotating.
Recommended idling speed: 2 500 rpm.
WARNING! Do not start the power cutter
without the cutting arm or cutting head fitted.
Otherwise the clutch can come loose and
cause personal injury.
Functioning, Final setting
Operation
•The carburetor governs the engine speed via the throttle. Air/
fuel are mixed in the carburetor
Jets
The carburetor is equipped with fixed jets to ensure the engine
always receives the correct fuel air mixture.
If the engine lacks power or accelerates poorly do the following:
•Inspect or, if necessary, replace the air filter.
•If this does not help, contact an authorised service workshop.

MAINTENANCE
Fuel filter
•The fuel filter sits inside the fuel tank.
•The fuel tank must be protected from contamination when
filling. This reduces the risk of operating disturbances caused
by blockage of the fuel filter.
•The filter cannot be cleaned but must be replaced with a new
filter when it is blocked. The filter should be changed at
least once per year.

Air filter
The air filter should be
cleaned regularly removing
dust and dirt to avoid:
•Carburettor malfunction
•Starting problems
•Reduced engine power
•Unnecessary wear to
engine parts
•Abnormal fuel consumption
The air filter system consists
of a main filter and a back-up
filter:
1)The main-filter is an oiled
foam filter that is easily
accessible under the filter
cover A. When used in
dusty conditions, this filter
should be checked/
replaced after every second
tank of fuel. The filter must
be cleaned and oiled
regularly to obtain a
satisfactory filtering effect.
There is a special
oil produced for
this purpose.
•Remove the filter. Wash the
filter carefully in tepid,
soapy water. After cleaning
rinse the filter thoroughly in
clean water. Squeeze out
the filter and let the filter
dry. NOTE! Compressed air
at a high pressure can
damage the foam.
•Oil the filter carefully. It is extremely important that the entire
filter is saturated in oil.
2)The back-up filter is a paper filter and is accessible from
under cover B. This filter should be changed/cleaned when
the engine’s output drops or after 1-2 weeks. The filter is
cleaned by shaking or carefully using compressed air. Note
the filter must not be washed!
A filter used for a long period of time can never be completely
cleaned. Therefore all air filters must be replaced periodically
with a new filter. A damaged air filter must always be
replaced.
IMPORTANT INFORMATION!
Insufficient care of the air filter will cause deposits on
the spark plug resulting in abnormal wear to engine
parts.
