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
mains-operated (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.
WARNING! The machine (Great Britain
110V) is not equipped with a ground fault
circuit interrupter. The machine must
always be used with an isolating
transformer for protection in case an
electrical fault should occur.

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, jeweller y 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 working area or in the material 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
• 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.

Cutting blades
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.
General
• Cutting blades are available in two basic designs;
abrasive baldes 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.

Hand-held, high-speed machines
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.
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 blades
The cutting material on abrasive blades 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.
Ensure the blade it not cracked or damaged in any other
way.
Test the abrasive blade by hanging it on your finger and
tapping it lightly with a screwdriver or the like. If the blade
does not produce a resonant, ringing sound it is
damaged.

Steel, steel alloys and other
hard metals.
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.
Dry cutting with diamond blade
WARNING! Avoid using abrasive blades
with water. The strength is impaired
!
when abrasive blades are exposed to
moisture.
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 core 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 blade is mounted on.
Always use a sharp diamond blade.
Material
Diamond blades are ideal for masonry, reinforced
concrete and other composite materials.
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.
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)
There is a flow limiter in the water connector that gives a
constant flow, irrespective of the water pressure. The flow
limiter may not be dismantled.
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 blades.
Abrasive blades must be stored on a flat, level
surface. If an abrasive blades is stored in humid
conditions, this can cause imbalance and result in
injury.
• Inspect new blades for transport or storage damage.

General working instructions
the material to be cut. This reduces the temperature of
the blade and ensures effective cutting.
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.
• 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.
• 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.
• 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
English – 13

SAFETY INSTRUCTIONS
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.
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.
• 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.

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.
There is an arrow on the machine that indicates the axleís
direction of rotation that the blade is mounted on.
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.
Checking the drive shaft 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.
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.
Do not use warped, notched, indented or dirty flange
washers. Do not use different dimensions of flange
washers.

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 shaft 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.
