All blades should be removed from the cutter after use and
stored carefully. Store cutting blades in dry, frost free
conditions.
Special care should be taken with abrasive discs. Abrasive
discs must be stored on a flat, level surface. If blades are
supplied with a backing pad then a spacer should be used to
keep them flat.
If an abrasive disc is stored in humid conditions, this can
cause imbalance resulting in injury.
Inspect new blades for transport or storage damage.
General working instructions
Basic safety rules
• Look around you:
- To ensure that people, animals or other things cannot
affect your control of the machine.
- To make sure that none of the above come into contact
with the cutting blade.
• Do not use the machine in bad weather, such as dense
fog, rain, strong wind, intense cold, etc. Working in bad
weather is tiring and can lead to dangerous conditions,
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.
• Always ensure you have a safe and stable working
position
• Make sure that no pipes or electrical cables are routed in
the area to be cut.
• Ensure the cord is behind you when you start to use the
machine so that the cord will not be damaged.
• The machine should be connected to an earthed outlet
socket.
Cutting
General
• Start cutting with the engine at full throttle.
• Always hold the power cutter in a firm grip with both
hands. Hold the machine so that the thumb and fingers
grip around the handle.
!
WARNING! This section describes basic
safety directions for using a power cutter.
This information is never a substitute for
professional skills and experience. If you get
into a situation where you feel unsafe, stop
and seek expert advice. Contact your dealer,
service agent or an experienced power
cutter user. Do not attempt any task that you
feel unsure of!
!
WARNING! The safety distance for the power
cutter is 15 metre. You are responsible that
animals and onlookers are not in the

SAFETY INSTRUCTIONS
Cutting technique
The technique described below is of a general character.
Check information for each blade regarding individual cutting
characteristics (for example, a diamond blades requires less
feeding pressure than an abrasive discs).
• Support the work piece in such away that you can predict
what will happen and so it will not pinch.
• Check that the blade is not in contact with anything when
the machine is started
• Always cut at full throttle.
• Start cutting gently, do not force or squeeze the blade in.
• Move the blade slowly backwards and forwards.
Use a small part of the blade’s cutting edge.
• Cut with the blade fully vertical – at right angles to the
work piece.
• The guard should be adjusted so that the rear section
rests against the work piece. Abrasive particles and
sparks are then collected by the guard and led away from
the user.
Sharpening diamond blades
Diamond blades can become dull when the wrong feeding
pressure is used or when cutting certain materials such as
heavily reinforced concrete. Working with a dull blade causes
overheating and finally the loss of a segment (part of a cutting
blade).
Sharpen against a soft material such as sandstone or 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.
How to avoid kickback
What is kickback?
The word kickback is used to describe the sudden reaction
that causes the power cutter and cutting blade to be thrown
from an object when the upper quadrant of the blade, known
as the kickback zone, touches an object.
Kickback only occurs when the cutting blades kickback zone
touches an object.
General rules
• Never cut with the cutting blades upper quadrant, i.e. the
kickback zone.
!
WARNING! Overexposure to vibration can
lead to circulatory damage or nerve damage
in people who have impaired circulation.
Contact your doctor if you experience
symptoms of overexposure to vibration.
These symptoms include numbness, loss of
feeling, tingling, pricking, pain, loss of
strength, changes in skin colour or
condition. These symptoms normally appear
in the fingers, hands or wrists.
!
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.
Do not pull the power cutter to one side, this
can cause the blade to jam or break
resulting in injury to people.
!
WARNING! Kickback can happen very
suddenly and violently; kicking the power
cutter and cutting blade back at the user. If
this happens when the cutting blade is
moving it can cause very serious, even fatal
injuries. It is vital you understand what
causes kickback and that you can avoid it by
taking care and using the right working
technique.

SAFETY INSTRUCTIONS
• Always hold the power cutter in a firm grip with both
hands. Hold the machine so that the thumb and fingers
grip around the handle.
• Keep a good balance and a firm foothold.
• Always cut at full throttle.
• Stand at a comfortable distance from the work piece.
• Take care when inserting the blade in an existing cut.
• Never cut above shoulder height.
• 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.
Pull in
Pull in occurs when the discs lower section suddenly stops or
when the cut closes. (To avoid, see the heading ”Basic rules”
and ”Jamming/rotation”, here below.)
Pinching/rotation
Pinching occurs when the cut closes. The power cutter can be
pulled down suddenly with a very powerful movement.
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.
Cutting blades
The machine must not be used with a rescue blade. The risk
of kick-back is greater with this type of cutting blade, as the
machine does not have a slipping clutch.
General
Cutting blades are available in two basic designs; abrasive
discs and diamond blades.
Always remove the cutting blade when the machine is
transported.
Make sure that the right bushing is used for the cutting blade
to be fitted on the machine. See the instructions under the
heading Assembling the cutting blade.
High speed portable tools
Our cutting blades are manufactured for high-speed, portable
power cutters. If blades from other manufacturers are used,
ensure that the blades conform to all regulations and
demands that concern this type of power cutter.
Special blades
Some cutting blades are designed for stationary equipment
and for use with attachments.Such cutting blades must not be
used on portable power cutters.
Always contact local authorities and make sure you are
following applicable directives.
Abrasive discs
The cutting material on abrasive discs consists of grit bonded
using an organic binder. ”Reinforced blades” are made up of
a fabric or fibre base that prevents total breakage at maximum
working speed if the blade should be cracked or damaged.
(The term reinforced does not refer to those cutting blades
that are only reinforced around the flange).
A cutting blade’s performance is determined by the type and
size of abrasive corn, and the type and hardness of the
bonding agent.
Characteristics that give the blade a shorter service life and
greater cutting capacity are said to make the blade ”softer”. A
blade with a longer service life and slower cutting capacity is
a blade with a ”harder” effect.
High quality cutting blades are normally more economical.
Lower quality cutting blades usually have an inferior cutting
capacity and shorter service life, which results in higher cost
per processed material.
!
WARNING! A cutting blade may burst and
cause injury to the operator.
Never use a cutting blade at a lower speed
rating than that of the power cutter.
Never use a cutting blade for any other
materials than that it was intended for.
Page 9
English

SAFETY INSTRUCTIONS
Check that the blade is approved for the same or higher
speed according to the aproval plate of the engine. Never use
a cutting blade with a lower speed rating than that of the
power cutter.
Ensure the blade it not cracked or damaged in any other way.
Test the abrasive disc by hitting it lightly with a piece of wood.
If the blade does not give a full-sounding ring then it is
damaged.
Diamond blades
Diamond blades for dry cutting are a new generation of
blades that do not require water cooling. However, the blades
are still damaged by excessive heat. It is good economics to
let the blade cool by simply lifting the blade from the cut every
30-60 seconds and let it rotate in the air, for 10 seconds to
cool.
Always use a sharp diamond blade.
General properties
Diamond blades give a lower cost per cutting operation, less
blade replacement, constant cutting depth and less dust.
When using diamond blades make sure that it rotates in the
direction indicated by the arrow on the blade.
There is an arrow on the rear of the machine that indicates the
axles direction of rotation that the disc is mounted on.

Diamond blades are ideal for masonry, reinforced concrete
and other composite materials. Diamond blades are not
recommended for cutting metal.

ASSEMBLY
Fitting the cutting blade
Partner cutting blades are manufactured and approved for
freehand cutting. The paper labels on each side of the blade
are there to distribute the pressure from the flange washer
and prevent the blade from slipping.
Fit the right bushing on the drive axle and then the cutting
blade on the bushing.
Different cutting blades have different inside measurements,
which is why different bushings must be used. Ensure that the
bushing to be used has the outside diameter intended for the
cutting blades inner diameter. The inner diameter
measurement is marked on the cutting blade.
The blade is placed between the flange hub (A) and the
flange washer (B). The flange washer is turned so that it fits
on the axle.
Tightening torque for the bolt holding the blade is: 15-25 Nm
(130-215 in.lb).
The cutting blade/axle can be locked by holding in the locking
button on the rear of the machine. The button is spring-loaded
and is reset when button is released.
When a diamond blade is mounted on the power cutter make
sure that the diamond blade will rotate in the direction
indicated by the arrow on the blade.
There is an arrow on the rear of the machine that indicates the
axles direction of rotation that the disc is mounted on.
When the cutting blade is replaced with a new blade check
the flanges and drive axle, see the instructions under the
heading Checking the drive axles and flanges.
Checking the drive shaft and flanges
Check that the threads on the drive shaft are undamaged.
Check that the contact surfaces of the cutting blade and
flanges are flat, run correctly on the spindle and are free from
foreign objects.
Do not use flanges that are twisted, have damaged edges,
untrue or dirty. Do not use different size flanges..
Blade guard
The blade guard should always be fitted on the machine.
The guard should be adjusted so that the rear section rests
against the work piece. Abrasive particles and sparks are
then collected by the guard and led away from the user.
!
WARNING! Always pull out the plug from the
outlet socket before cleaning, maintenance
or assembly.

MAINTENANCE
Maintenance
Partner’s power cutters are robust and durable. However, as
they are used at a high processing rate all service procedures
must be carried out at the times and in the manner described,
so that the machine always works efficiently and safely.
Cooling system
The machine is equipped with an efficient fan to cool the
motor.
Cooling air which is drawn in through the grille by the
machines rear handle passes over the stator and rotor and
out through the front of the motor housing.
In order for the machine to always be cooled sufficiently the
cooling air openings must be kept clear and clean. Blow down
the machine regularly with compressed air.
Replacing the carbon brushes
Check the carbon brushes at least once a month. The carbon
brushes should be replaced with new brushes if they are
worn, cracked or in any other way deformed.
All carbon brushes must be replaced when the brushes are
replaced.
• Remove both inspection covers by loosening both screws.
• Unscrew the cable holding the carbon brush. Now lift up
the spring and then lift out the carbon brush from the
brush retainer.
• Clean the brush retainers with a dry brush.
• Carefully blow away the dust.
• Fit the new carbon brushes and, at the same time, check
that they slide easily in the brush retainers.
• Fold down the springs and tighten the cable.
• New carbon brushes must be run in for approximately 40
minutes while idling.
Bevel gear
The grease in the gear housing should be changed every 4
months. Use high quality gear grease
The gear housing must not be filled completely with grease.
The grease expands as the machine heats up during
operation. If the gear housing was completely filled with
grease it could damage the seals and lead to leakage of
grease.
The gear housing should contain 90 g of grease in total.
Changing the grease
The following parts must be dismantled to change the grease
in the gear housing:
1 Flange washers holding the cutting blade
2 Support flange for the guard
3 Guard
4 The four screws holding the shield. Lift the shield together
with the drive wheel unit out of the gear housing.
5 Wipe out the grease and fill with new, good quality gear
grease. The gear housing should contain 90 g of grease
in total.
CAUTION! Exercise care when dismantling so as not to
damage the gaskets. These are used both as seals and
spacers for the gear setting.
!
WARNING! Inspection and/or maintenance
should be carried out with the motor
switched off and the plug disconnected.
