SAFETY INSTRUCTIONS
General safety warnings
WARNING! Read all safety warnings and all
instructions. Failure to follow the warnings
!
and instructions may result in electrtic
shock, fire and/or serious injury.
Save all warnings and instructions for future reference.
The term ”power tool” in the warnings refers to your mainsoperated (corded) power tool or battery-operated (cordless)
power tool.
Work area safety
• Keep work area clean and well lit. Cluttered or dark areas
invite accidents.
• Do not operate power tools in explosive atmospheres,
such as in the presence of flammable liquids, gases or
dust. Power tools create sparks which may ignite the dust
or fumes.
• Keep children and bystanders away while operating a
power tool. Distractions can cause you to lose control.
• 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.
• Ensure when cutting that no material can become loose
and fall, causing operating injury.Take great care when
working on sloping ground.
WARNING! The safety distance for the power
cutter is 15 metres. You are responsible to
!
ensure that animals and onlookers are not
within the working area. Do not start cutting
until the working area is clear and you are
standing firmly.
Electrical safety
• Power tool plugs must match the outlet. Never modify the
plug in any way. Do not use any adapter plugs with
earthed (grounded) power tools. Unmodified plugs and
matching outlets will reduce the risk of electric shock.
• Avoid body contact with earthed or grounded surfaces,
such as pipes, radiators, ranges and refrigerators. There
is an increased risk of electric shock if your body is
earthed or grounded.
• The power tool should not be exposed to more moisture
than what is supplied by the low flushing water system. Do
not expose the power tool to rain. Water entering a power
tool will increase the risk of electric shock.
• Do not abuse the cord. Never use the cord for carrying,
pulling or unplugging the power tool. Keep cord away from
heat, oli, charp edges or moving parts. Damaged or
entangled cords increase the risk of electric shock.
• When operating a power tool outdoors, use an extension
cord suitable for outdoor use. Use of cord suitable for
outdoor use reduces the risk of electric shock.
• Check that the cord and extension cord are intact and in
good condition. Never use the machine if the cord is
damaged, hand it in to an authorized service workshop for
repair.
• Do not use an extension cord while it is rolled up to avoid
overheating.
• When using an extension cable, use only certified
extension cables with sufficient reach. For more
information, see "Recommended cable dimensions" in the
"Technical data" section. An undersized cable means a
risk of reduced machine capacity and overheating.
• The machine should be connected to an earthed outlet
socket. Check that the mains voltage corresponds with
that stated on the rating plate on the machine.
• Ensure the cord is behind you when you start to use the
machine so that the cord will not be damaged.

SAFETY INSTRUCTIONS
Personal safety
• Stay alert, watch what you are doing and use common
sense when operaing a power tool. Do not use a power
tool while you are tired or under the influence of drugs,
alcohol or medication. A moment of inattention while
operating power tools may result in serious personal
injury.
• Use personal protective equipment. Always wear eye
protection. Protetctive equipment such as dust mask,
non-skid safety shoes, hard hat, or hearing protection
used for appropriate conditions will reduce personal
injuries.
• Prevent unintentional starting. Ensure the switch is in the
OFF-position before connecting to power source and/or
battery pack, picking up or carrying the tool. Carrying
power tools with your finger on the switch or energising
power tools that have the switch on invites accidents.
• Remove any adjusting key or wrench before turning the
power tool on. A wrench or a key left attached to a rotating
part of the power tool may result in personal injury.
• Do not overreach. Keep proper footing and balance at all
times. This enables better control of the power tool in
unexpected situations.
• Dress properly. Do not wear loose clothing or jewellery.
Keep your hair, clothing and gloves away from moving
parts. Loose clothes, jewellery or long hair can be caught
in moving parts.
• If devices are provided for the connection of dust
extraction and collection facilities, ensure that these are
connected and properly used. Use of dust collection can
reduce dust-related hazards.
• Remain at a distance from the blades when the engine is
running.
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.
Power tool use and care
• Do not force the power tool. Use the correct power tool for
your application. The correct power tool will do the job
better and safer at the rate for which it was designed.
• Do not use the power tool if the switch does not turn it on
and off. Any power tool that cannot be controlled with the
switch is dangerous and must be repaired.
• Disconnect the plug from the power source and/or the
battery pack from the power tool before making any
adjustments, changing accessories, or storing power
tools. Such preventive safety measures reduce the risk of
starting the power tool accidentally.
• Store idle power tools out of the reach of children and do
not allow persons unfamiliar with the power tool or these
instructions to operate the power tool. Power tools are
dangerous in the hands of untrained users.
• Maintain power tools. Check for misalignment or binding
of moving parts, breakage of parts and any other
condition that may affect the power tool´s operation. If
damaged, have the power tool repaired before use. Many
accidents are caused by poorly maintained power tools.
• Keep cutting tools sharp and clean. Properly maintained
cutting tools with sharp cutting edges are less likely to
bind and are easier to control.
• Use the power tool, accessories and tool bits etc. in
accordance with these instructions, taking into account
the working conditions and the work to be performed. Use
of the power tool for operations different from those
intended could result in hazardous situations.
• Never use a machine that has been modified in any way
from its original specification.
• Make sure that no pipes or electrical cables are routed in
the area to be cut.
• Always check and mark out where gas pipes are routed.
Cutting close to gas pipes always entails danger. Make
sure that sparks are not caused when cutting in view of
the risk of explosion. Remain concentrated and focused
on the task. Carelessness can result in serious personal
injury or death.
• The guard for the cutting equipment must always be on
when the machine is running.
Service
8 – English
• Have your power tool serviced by a qualified repair person
unsing only identical replacement parts. This will ensure
that the safety of the power tool is maintained.

• A defective power switch should be replaced by an
authorized service workshop.
Power switch lock
The power switch lock is designed to prevent accidental
operation of the switch. When the lock (A) is pressed in the
power switch (B) is released.
The machine is equipped with electronically controlled
gradual start and overload protection.
The engine starts to pulsate if the machine is loaded above a
specific level. If the load is reduced the engine reverts to its
normal state and cutting can resume.
The electronics will cut the current after a set time if the
machine continues to be run with a pulsating engine. The
higher load the faster the shutoff.
The electronics cut the current immediately if the blade jams.
Guard for the blade
This guard is fitted above the cutting blade and is designed to
prevent parts of the blade or cutting fragments from being
thrown towards the user.
Checking the blade guard
The power switch lock remains depressed as long as the
power switch is depressed. When the grip on the handle is
released both the power switch and power switch lock are
reset. This movement is controlled by two independent return
springs. This position results in the machine stopping and the
power switch being locked.
WARNING! Always check that the guard is
correctly fitted before starting the machine.

purpose than that it was intended for.
General
• Cutting blades are available in two basic designs;
abrasive discs and diamond blades.
• High-quality blades are often most economical. Lower
quality blades often have inferior cutting capacity and a
shorter service life, which results in a higher cost in
relation to the quantity of material that is cut.
• 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.
• Start the machine.
• Push the TEST button (blue).
• The ground fault circuit interrupter should trip and the
machine switch off instantly. If not, contact your dealer.

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.
10 – English
Page 11
SAFETY INSTRUCTIONS
Blade vibration
The blade can become out-of-round and vibrate if an
excessive feed pressure is used.
A lower feed pressure can stop the vibration. Otherwise
replace the blade. The blade must be of the recommended
type for the material to be cut.
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.
A cutting blade’s performance is determined by the type and
size of abrasive corn, and the type and hardness of the
bonding agent.
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.
Diamond blades
WARNING! Cutting plastics with a diamond
blade can cause kickback when the material
!
melts due to the heat produced when cutting
and sticks to the blade.
Diamond blades consist of a steel body provided with
segments that contain industrial diamonds.
Diamond blades ensure lower costs per cutting operation,
fewer blade changes and a constant cutting depth.
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 machine that indicates the axleís
direction of rotation that the disc is mounted on.
Ensure the blade it not cracked or damaged in any other way.
Test the abrasive disc by hanging it on your finger and tapping
it lightly with a screwdriver or the like. If the disc does not
produce a resonant, ringing sound it is damaged.
Abrasive discs for different materials
Disc type Material
Concrete, asphalt, stone masonry,
Concrete disc
Metal disc
!
cast iron, aluminium, copper,
brass, cables, rubber, plastic, etc.
Steel, steel alloys and other hard
metals.
WARNING! Avoid using abrasive discs with
water. The strength is impaired when
abrasive discs are exposed to moisture.
Always use a sharp diamond blade.
Material
Diamond blades are ideal for masonry, reinforced concrete
and other composite materials. Diamond blades are not
recommended for cutting metal.
Diamond blades are available in several hardness classes. A
"soft" diamond blade has a relatively short service life and
large cutting capacity. It is used for hard materials such as
granite and hard concrete. A "hard" diamond blade has a
longer service life and reduced cutting capacity, and should
be used for soft materials such as brick and asphalt.
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 blunt diamond
blade causes overheating, which can result in the diamond
segments coming loose.
Sharpen the blade by cutting in a soft material such as
sandstone or brick.

SAFETY INSTRUCTIONS
Dry cutting with diamond blade
WARNING! Diamond blades get very hot
when used. A heated blade can be deformed
!
and cause damage to the machine as well as
the user.
When dry cutting, lift the blade out from the
cut every 30–60 seconds and let it rotate in
the air for 10 seconds to let it cool.
Wet cutting with diamond blade (K3000 Wet)
Water cooling, which is used when cutting concrete, cools the
blade and increases its service life while also reducing the
formation of dust.
WARNING! Diamond blades get very hot
when used. A heated blade can be deformed
!
and cause damage to the machine as well as
the user.
When wet cutting, the blade is continuously
cooled to prevent overheating.
Water connection with flow limiter (K3000 Wet)
General working instructions
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!
Cutting technique
The technique described below is of a general character.
Check information for each blade regarding individual cutting
characteristics (for example, diamond blades requires less
feeding pressure than an abrasive discs).
• Support the work piece in such a way that it is possible to
predict what will happen, and so that the cut remains open
while cutting.
There is a flow limiter in the water connector that gives a
constant flow, irrespective of the water pressure. Le limiteur
de débit ne peut être démonté.
Transport and storage
• Do not store or transport the power cutter with the cutting
blade fitted. All blades should be removed from the cutter
after use and stored carefully.
• Special care should be taken with abrasive discs.
Abrasive discs must be stored on a flat, level surface. If an
abrasive disc is stored in humid conditions, this can cause
imbalance and result in injury.
• Inspect new blades for transport or storage damage.
• Ensure that the cutting blade is fitted correctly.
• Always hold the machine in a firm grip with both hands.
Hold it so that the thumbs and fingers grip round the
handles.
• Check that the blade is not in contact with anything when
the machine is started
• Start cutting with the machine running at maximum
speed.
• Start cutting smoothly, allowing the machine to work
without forcing or pressing in the blade. Always cut at
maximum speed.
• Move the blade slowly forwards and backwards to achieve
a small contact area between the blade and the material
to be cut. This reduces the temperature of the blade and
ensures effective cutting.
12 – English
Page 13
SAFETY INSTRUCTIONS
• The guard for the cutting equipment should be adjusted so
that the rear section is flush with the work piece. Spatter
and sparks from the material being cut are then collected
up by the guard and led away from the user.
• Feed down the machine in line with the blade. Pressure
from the side can damage the blade and is very
dangerous.
WARNING! Under all circumstances avoid
grinding 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.
How to avoid kickback
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.
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.
General rules
• Never start to cut with the upper quadrant of the blade as
shown in the figure, also known as the kickback zone.
• Always hold the machine in a firm grip with both hands.
Hold it so that the thumbs and fingers grip round the
handles.
• Keep a good balance and a firm foothold.
• Always cut at maximum speed.
• 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 disc’s lower section suddenly stops or
when the cut closes. (To avoid, see the heading ”Basic rules”
and ”Jamming/rotation”, here below.)
Pinching/rotation
If the cut is pressed together this can lead to jamming. The
machine can be pulled down suddenly with a very powerful
jerk.
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.

Fitting the cutting blade
Husqvarna’s blades are approved for hand-held power
cutters. Blades are manufactured with three different
diameters of centre holes: 20 mm (0.787"), 22.2 mm (7/8")
and 25.4 mm (1"). Bushings can be fitted on the machine axle
to adjust the machine to the centre hole of the blade. Use a
bushing with the correct diameter! The blades are marked
with the diameter of the centre hole.
Checking the drive axle and flange
washers
Check that the threads on the drive shaft are undamaged.
Check that the contact surfaces on the blade and the flange
washers are undamaged, of the correct dimension, clean,
and that they run properly on the drive axle.
Do not use warped, notched, indented or dirty flange
washers. Do not use different dimensions of flange washers.
The blade is placed on the bushing (C) between the inner
flange washer (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 machine that indicates the axleís
direction of rotation that the disc is mounted on.
Guard for the blade
The guard must always be fitted on the machine.
The guard for the cutting equipment should be adjusted so
that the rear section is flush with the work piece. Spatter and
sparks from the material being cut are then collected up by
the guard and led away from the user.
When the blade is replaced with a new one, check the flange
washers and the drive axle. See instructions under the
heading Checking the drive axle and flange washers.

WARNING! K3000 is not equipped with
ground fault circuit interrupter. Do not wash
!
the machine with water, as water can enter
the electrical system or the engine and
cause damage to the machine or short
circuit.

WARNING! Do not use a high pressure
washer when rinsing the inside of the
!
machine.
The machine can withstand taking in damp air and splashes
during the cutting process. Clean water does not affect the
machine’s function.
When cutting materials such as concrete or brick, which can
contain salt, you must rinse the machine after the work is
finished. The cleaning reduces the risk for accretions building
up inside the engine, which can cause leakage current
between electric components, which in turn can cause the
ground fault circuit interrupter to turn off without intention.
• Clean the machine daily by rinsing it with clean water after
the work is finished.
• Place the machine with the rear handle facing upwards.
Rinse the air intakes at the rear handle with clean water.
The water will run out through the front air outlets.
• Connect the plug and run the engine dry for approx. 30
sec in order to speed up the drying of the engine.
• 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.

MAINTENANCE
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 The sealing ring
3 Support flange for the guard
4 Guard for the blade
5 The four screws holding the shield. Lift the shield together
with the drive wheel unit out of the gear housing.
Checking the drive axle and flange
washers
Check that the threads on the drive shaft are undamaged.
Check that the contact surfaces on the blade and the flange
washers are undamaged, of the correct dimension, clean,
and that they run properly on the drive axle.
Do not use warped, notched, indented or dirty flange
washers. Do not use different dimensions of flange washers.
Checking water connection with
flow limiter
Check and clean the filter in the connection regularly and
change it when needed.
1 Unscrew the connector.
2 Press out the filter (A) using a screwdriver or the like.
3 Clean or change the filter.
4 When refitting - make sure that the flow limiter (B) is
correctly adjusted, with the concave face turned towards
the clutch connection.
6 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.
Daily maintenance
1 Check that nuts and screws are tight.
2 Check that the power switch unit works smoothly.
3 Clean the outside of the machine.
4 Checking the blade guard
5 Check the condition of the cutting blade.
6 Check and clean the cooling air openings.
7 Check that the cord and extension cord are intact and in
good condition.

WARNING! Cutting, especially when DRY
cutting, generates dust that comes from the
!
material being cut, which frequently
contains silica. Silica is a basic component
of sand, quartz, brick clay, granite and
numerous other minerals and rocks.
Exposure to excessive amount of such dust
can cause:
Respiratory disease (affecting your ability to
breath), including chronic bronchitis,
silicosis and pulmonary fibrosis from
exposure to silica. These diseases may be
fatal;
Skin irritation and rash.
Cancer according to NTP* and IARC*
*/ National Toxicology Program, International
Agency for Resaearch on Cancer
Take precautionary steps:
Avoid inhalation of and skin contact with
dust, mist and fumes.
Wear and ensure that all bystanders wear
appropriate respiratory protection such as
dust masks designed to filter out
microscopic particles. (See OSHA 29 CFR
Part 1910.1200)
Wet cut when feasible, to minimize dust.
