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

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 opera-
tion. 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.

FUEL HANDLING
!
Fuelling
WARNING!The following precautions reduce
the risk of fire:
•Do not smoke or place any sources of heat in
the vicinity of the fuel.
•Never refuel when the engine is running.
•Open the fuel cap slowly when fuelling so
that any over pressure is released slowly.
•Tighten the fuel cap carefully after refuelling.
•Always move the machine from the fuelling
place before starting.
•Keep the handle dry, clean
and free from oil and fuel.
•Clean around the fuel cap.
Clean the fuel tank
regularly. The fuel filter
should be changed at least
once per year
Contamination in the tank
can disrupt operations.
Ensure that the fuel is well
mixed by shaking the
container before filling the
tank.
•Always exercise care when
filling the fuel. Move the
power cutter at least three
metres from the filling area
before starting. Make sure
the fuel cap is tightened.
IMPORTANT! The power cutter is equipped with a two-stroke
engine and must always been run using a mixture of gasoline
and two-stroke engine oil. It is important to accurately measure
the amount of oil to be mixed to ensure that the correct mixture
is obtained. When mixing small amounts of fuel, even small
inaccuracies can drastically affect the ratio of the mixture.
Always provide for good ventilation when
handling fuel.
!
Fuelmix
Petrol
•Use good quality unleaded
or leaded petrol.
•The lowest octane
recommended is 90.
•If you run the engine on a
lower octane grade than 90
so-called, knocking can
occur. This gives rise to a
high engine temperature,
which can result in serious
engine damage.
Two-stroke oil
•For the best results use
PARTNER two-stroke oil,
which is especially
developed for power
cutters. Mixing ratio 1:50
(2%).
•If PARTNER two-stroke oil
is not available, you may
use another two-stroke oil of
good quality that is intended
for air cooled engines.
Contact your dealer when
selecting an oil. Mixing ratio
1:33 (3%)-1:25 (4%).
•Never use two-stroke oil
intended for water cooled
outboard engines, so-called,
outboard oil.
•Never use oil intended for
four-stroke engines.
Mixing
•Always mix the petrol and
oil in a clean container
intended for fuel.
•Always start by filling half
the amount of the petrol to
be used. Then add the
entire amount of oil. Mix
(shake) the fuel mixture.
Add the remaining amount
of petrol.
•Mix (shake) the fuel mixture
thoroughly before filling the
saw’s fuel tank.
•Do not mix more than max.
one month’s supply of fuel.
•If the power cutter is not
used for some time the fuel
tank should be emptied and
cleaned.

Pull out the choke.
STARTER THROTTLE
CATCH
Press in the throttle control
and thereafter the starter
throttle catch (A). Release the
throttle control and the throttle
is blocked in half throttle
position. The catch is released
when the throttle control is
pressed in all the way.
DECOMPRESSION VALVE
Press in the valve to reduce
the pressure in the cylinder,
this makes starting the power
cutter easier. The
decompression valve should
always be used when starting.
When the machine has
started the valve automatically
returns to its original position.
Start and stop
WARNING! Before starting observe the
following:
•Do not start the power cutter without the
cutting arm or cutting head fitted. Otherwise
the clutch can come loose and cause perso
nal injury.
•Always move the power cutter from the
filling area before starting.
•Ensure that you and the machine stand
firmly and that the cutting blade rotates
freely.
•Make sure no unauthorised persons are
within the working area.

START AND STOP
Start
Take hold of the front handle
using your left hand. Place
your right foot on the lower
section of the rear handle and
press the power cutter against
the ground. Never twist the
starter cord around your
hand.
Grip the starter with your right
hand, and slowly pull the
starter cord out until you feel
some resistance (the pawls
grip) now pull quickly and
powerfully.
NOTE! Do not pull out the
starter cord completely and do
not release the starter from
the fully extended position.
This can damage the power
cutter.
When the engine starts,
quickly apply full throttle and
the starter throttle catch will
automatically disengage.
WARNING! The cutting blade can rotate when
the engine starts. Make sure it can rotate
freely.

Adjusting the drive belt
• The drive belt is fully
enclosed and well protected
from dust, dirt and
mechanical effects during
the cutting process.
• To tension the drive belt,
remove the belt cover and
loosen the belt tensioner
bolt slightly, then apply firm
thumb pressure on the
tension roller and tighten
the tensioner bolt.
MAINTENANCE
!
Belt tensioning/changing the drive
belt
• Remove the belt cover and
loosen the belt tensioner
bolt slightly. Push back the
tension roller and install the
new belt.
Note: Make sure that the two
belt pulleys are clean before
installing a new belt.
• Apply firm thumb pressure
on the tension roller and
tighten the tensioner bolt.
• To assemble reverse the
procedure for dismantling.
WARNING! Never use a power cutter without a
blade guard over the cutting blade.
Belt pulley and clutch
Never start the engine when the belt pulley and clutch are
remove for maintenance.
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.
Carburetor
Your Partner product has been designed and manufactured to
specifications that reduce harmful emissions.
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. A correctly adjusted idle speed setting occurs
when the engine runs smoothly in every position. It should also
be good margin to the rpm when the blade starts to rotate.
Recommended idling speed: 2 500 rpm.

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 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 an oiled main foam filter
and a paper filter:
1)The foam filter is easily
accessible under the filter
cover A. This filter shall be
checked once a week and
replaced when needed.
•The filter must be replaced
or cleaned and oiled
regularly to obtain a
satisfactory filtering effect.
Use a Partner Foam filter
oil for re-oiling.
•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 paper filter is accessible from under cover B. This filter
shall be checked once a week and replaced when needed.
The paper filter cannot be cleaned and must not be washed.
IMPORTANT INFORMATION!
Insufficient care of the air filter will cause deposits on
the spark plug resulting in abnormal wear to engine
parts.

Replacing a broken or worn starter cord
•Loosen the bolts that hold
the starter against the
crankcase and lift off the
starter unit.
•Remove any remaining rope
from the pulley and check
that the return spring
recoils. Insert the new
starter rope through the
pulley.
•Anchor the rope around the
hub on the pulley as shown
on the illustration. Pull the
rope tight and make sure
that the free end is as short
as possible.
!
Tensioning the recoil spring
•Lift up the starter cord from
the cut out on the pulley and
turn the pulley approx.
7 turns clockwise.
NOTE! Ensure the starter
pulley can be turned at least
a further 1/2 turn when the
starter cord is fully
extended.
Replacing a broken recoil spring
•Lift the starter pulley (see
"Changing a broken or worn
starter cord"
).
•Loosen the screws holding
the spring cassette.
•Disassemble the recoil
spring by tapping the pully

lightly against a working
bench or similar. If the
spring pops out when
assembling, it should be
mounted again, out and in
towards the centre.
•Lubricate the recoil spring
with thin oil. Assemble the
starter pulley, and tension
the recoil spring.
Starter
WARNING!
•The recoil spring sits in its tensioned posi
tion in the starter housing and can with
careless handling fly out and cause personal
