SAFETY INSTRUCTIONS  
Electrical safety  
General safety warnings  
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.  
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.  
!
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.  
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.  
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.  
Work area safety  
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.  
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.  
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.  
Keep children and bystanders away while operating a  
power tool. Distractions can cause you to lose control.  
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 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.  
Do not use an extension cord while it is rolled up to avoid  
overheating.  
Ensure when cutting that no material can become loose  
and fall, causing operating injury.Take great care when  
working on sloping ground.  
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 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.  
WARNING! 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.

SAFETY INSTRUCTIONS  
Personal safety  
Power tool use and care  
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.  
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.  
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.  
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.  
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.  
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.  
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.  
Keep cutting tools sharp and clean. Properly maintained  
cutting tools with sharp cutting edges are less likely to  
bind and are easier to control.  
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.  
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.  
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.  
Never use a machine that has been modified in any way  
from its original specification.  
Remain at a distance from the blades when the engine is  
running.  
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.  
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.  
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  
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.

Switch  
The power switch should be used to start and stop the  
machine.  
Gradual start and overload protection  
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.  
Checking the power switch  
Start the machine, release the power switch and check  
that the engine and the cutting blade stop.  
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  
A defective power switch should be replaced by an  
authorized service workshop.  
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.

General  
Cutting blades are available in two basic designs;  
abrasive discs and diamond blades.  
Check the ground fault circuit interrupter  
Connect the machine to the socket. Push the RESET  
button (green) and the red LED lights up.  
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.

SAFETY INSTRUCTIONS  
Blade vibration  
Diamond blades  
The blade can become out-of-round and vibrate if an  
excessive feed pressure is used.  
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.  
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.  
!
Diamond blades consist of a steel body provided with  
segments that contain industrial diamonds.  
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.  
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.  
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.  
There is an arrow on the rear of the machine that indicates the  
axles direction of rotation that the disc is mounted on.  
Ensure the blade it not cracked or damaged in any other way.  
Always use a sharp diamond blade.  
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.  
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.  
Abrasive discs for different materials  
Disc type  
Material  
Sharpening diamond blades  
Concrete, asphalt, stone masonry,  
cast iron, aluminium, copper,  
brass, cables, rubber, plastic, etc.  
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.  
Concrete disc  
Steel, steel alloys and other hard  
metals.  
Metal disc  
Sharpen the blade by cutting in a soft material such as  
sandstone or brick.  
WARNING! Avoid using abrasive discs with  
water.The strength is impaired when  
abrasive discs are exposed to moisture.

SAFETY INSTRUCTIONS  
Dry cutting with diamond blade  
General working instructions  
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.  
!
WARNING! This section describes basic  
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.  
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!  
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.  
Cutting technique  
WARNING! Diamond blades get very hot  
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).  
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.  
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.  
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. Le limiteur  
de débit ne peut être démonté.  
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  
 
 
SAFETY INSTRUCTIONS  
The guard for the cutting equipment should be adjusted so  
General rules  
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.  
Never start to cut with the upper quadrant of the blade as  
shown in the figure, also known as the kickback zone.  
Feed down the machine in line with the blade. Pressure  
from the side can damage the blade and is very  
dangerous.  
Always hold the machine in a firm grip with both hands.  
Hold it so that the thumbs and fingers grip round the  
handles.  
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.  
!
Keep a good balance and a firm foothold.  
Always cut at maximum speed.  
Do not pull the power cutter to one side, this  
can cause the blade to jam or break  
resulting in injury to people.  
Stand at a comfortable distance from the work piece.  
Take care when inserting the blade in an existing cut.  
Never cut above shoulder height.  
How to avoid kickback  
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 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.  
!
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  
What is kickback?  
If the cut is pressed together this can lead to jamming. The  
machine can be pulled down suddenly with a very powerful  
jerk.  
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.  
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.

ASSEMBLY  
Checking the drive axle and flange  
washers  
Assembly  
Check that the threads on the drive shaft are undamaged.  
WARNING! Always pull out the plug from the  
outlet socket before cleaning, maintenance  
or assembly.  
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.  
!
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.  
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.  
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.  
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 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! 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*  
*/ NationalToxicology 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.
