deformations.  
Basic safety rules  
Look around you:  
-To ensure that people, animals or other things cannot affect  
your control of the machine.  
General safety precautions  
- To make sure that none of the above might come into  
contact with the cutting equipment.  
A power cutter is designed to cut hard materials, such as  
masonry. Observe the increased risk of kickback when  
cutting soft materials. See instructions under the heading  
How to avoid kickback.  
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 the power cutter until you have read the entire  
contents of this Operator’s Manual.  
All servicing, in addition to the points listed in the section  
”Control, maintenance and service of the power cutter’s  
safety equipment”, should be carried out by trained  
service specialists.  
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.  
Never use the machine if you are tired, if you have drunk  
alcohol, or if you are taking medication that could affect  
your vision, your judgement or your co-ordination.  
Make sure that no clothes or parts of the body come in  
contact with the cutting equipment when it is rotating.  
Wear personal protective equipment. See instructions  
under the heading Personal protective equipment.  
Keep at a safe distance from the cutting equipment when  
it is rotating.  
Never use a machine that has been modified in any way  
from its original specification.  
The guard for the cutting equipment must always be on  
when the machine is running.  
Never use a machine that is faulty. Carry out the checks,  
maintenance and service instructions described in this  
manual. Some maintenance and service measures must  
be carried out by trained and qualified specialists. See  
instructions under the heading Maintenance.  
Ensure that the working area is sufficiently illuminated to  
create a safe working environment.  
Do not move the machine when the cutting equipment is  
rotating.  
Never allow anyone else to use the machine without first  
ensuring that they have understood the contents of the  
operator’s manual.  
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.  
Transport and storage  
Do not store or transport the power cutter with the blade fitted.  
Store the power cutter in a lockable area so that it is out of  
reach of children and unauthorised persons.  
The blade should be removed from the machine after use and  
stored well. Store the blade in the dry.

SAFETY INSTRUCTIONS  
Move the blade slowly backwards and forwards to give a  
Cutting  
small contact surface between the blade and material to  
be cut.This will mean the blade temperature is kept down  
resulting in efficient cutting.  
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.  
!
General  
Feed the machine in line with the blade.Side pressure can  
destroy the blade and is extremely dangerous.  
Start cutting with the machine running at maximum  
speed.  
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  
cutting with the side of the blade, as this will  
definitely result in damage, breakage or can  
cause serious injuries. 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! 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.  
!
Cutting depth  
K3600 MKII can cut up to a depth of 260 mm (10 inches).  
Making a guide cut of 50-70 mm (2-3 inches) first, gives you  
better control of the machine. This means the water disc can  
penetrate into the workpiece and help control the machine.  
Attempting to saw the entire depth in one run takes longer.  
Working with several runs, 3 to 4 when the cut is 260 mm (10  
inches) in depth, is much quicker.  
Cutting technique  
The technique described below is of a general character.  
Check the details of each blade concerning individual cutting  
characteristics.  
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.  
Check that the blade is not in contact with anything when  
the machine is started.  
Always cut at maximum speed.  
Start cutting gradually, let the machine work without  
forcing or pressing the blade.

SAFETY INSTRUCTIONS  
Large work  
How to avoid kickback  
Cuts exceeding 1 m - secure a batten along the line to be cut.  
The batten acts as a guide. Use this guide to make a marking  
cut along the entire length of the cut, 50-70 mm (2-3 inches)  
in depth. Remove the guides once the marking cut has been  
made.  
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.  
Small work  
First make a shallow marking cut, max 50-70 mm (2-3 inches)  
in depth. Now make the final cut.  
Cutting sequence  
First make the lower horizontal cut.Now make the two vertical  
cuts. Finish with the upper horizontal cut.  
Remember to divide the blocks up into manageable pieces so  
that they can be transported and lifted safely.  
General rules  
Never start to cut with the upper quadrant of the blade as  
shown in the figure, also known as the kickback zone.  
CAUTION! If the upper horizontal cut is made before the  
lower horizontal cut, the work piece will fall on the blade and  
jam it.  
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.

SAFETY INSTRUCTIONS  
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.  
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.  
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.  
!
Sharpen the blade by cutting in a soft material such as  
sandstone or brick.  
Pull in  
Vibrations on diamond blades  
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.)  
The blade can become out of round and vibrate if a too high  
feed pressure is used.  
A lower feed pressure can stop the vibration. Otherwise  
replace the blade.The blade shall be intended for the material  
to be cut.  
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.  
Diamond blades  
Diamond blades consist of a steel body provided with  
segments that contain industrial diamonds.  
Always use a sharp diamond blade. Sharpen the blade by  
cutting in a soft material such as sandstone or brick.  
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.  
Diamond blades are ideal for masonry, reinforced concrete  
and other composite materials. Diamond blades are not  
recommended for cutting metal.  
Water cooling  
WARNING! Cool diamond blades  
continuously with water to prevent  
overheating that can cause the diamond  
blade to break and pieces being thrown off  
resulting in injury and damage.  
!
Diamond blades should be sprinkled with water while cutting  
to cool the blade and to bind dust that forms while cutting.

SETTINGS AND ADJUSTMENTS  
Drive  
Fitting the blade  
On account of the machine’s unique design the driving power  
is not transferred at the centre of the blade.The flanges on the  
two guide rollers run in the blade’s grooves. Springs on the  
guide rollers press out the rollers, which in turn press the V-  
shaped edge on the inside diameter of the blade against the  
V-shaped groove in the drive wheel. The drive wheel is fitted  
on an axle which is driven by the hydraulic motor.  
WARNING! Always disconnect the power  
cutter from the hydraulic connection when  
performing a service. Unexpected blade  
movements can cause serious injuries.  
!
We offers a number of blades for different materials in its  
range.Check with your Husqvarna dealer to see which blades  
are best suited for your usage.  
This allows a total cutting depth of 260 mm (10 inches) with a  
350 mm (14 inches) diamond blade.  
WARNING! It is forbidden to reconstruct a  
used blade. A used blade may be weakened.  
A reconstructed blade can crack or break  
into pieces and seriously injury the operator  
or other persons.

the guide rollers still enter the blade’s grooves correctly.  
Now tighten the three screws fully.  
Pull out the lock for the front handle and move the handle  
to the service position.  
Rotate the blade and make sure that the support rollers  
are not clamped against the blade.  
Remove the three screws holding the support roller guard  
using a 6 mm hex key and lift off the cover.  
Adjust the adjuster screws so that the support rollers  
make contact against the blade.  
Fit the blade.  
Adjust so you can easily stop the support rollers using  
your thumb when the blade is rotated.The support rollers  
should only follow the blade occasionally.  
CAUTION! The blade has a groove (A) on one side that  
acts a the guide groove for the support rollers.Ensure that  
theV-shaped edge of the blade enters the drive wheel and  
that the blade’s guide groove fits in the guide rollers. Also  
see under the heading Drive.  
Tighten the locking nuts on the support roller guard.  
Press in the guide roller if necessary, so that it climbs into  
the groove on the blade.

SETTINGS AND ADJUSTMENTS  
CAUTION!The machine should be upright. If the machine  
lies on its side the weight of the blade makes it difficult to  
make a correct adjustment.  
Water hose  
Connect the water hose to the water supply.The water flow is  
activated by opening the check valve. Minimum water flow: 4  
l/min Note that the machine’s hose nipple is fitted with a filter.  
Tighten the knobs fully and the machine is ready to use.  
Water supply  
When you press in the switch lock (A) the water valve opens.  
The water valve remains open and the switch lock (A) remains  
pressed in as long as the switch (B) is held pressed in.  
Hydraulic hoses  
WARNING! The power cutter must not be  
connected to a hydraulic pressure  
exceeding 150 bar (3000 psi).  
!
Before connecting the hoses: Ensure that the couplings  
are clean, both on the machine and the hoses.  
Connect the pressure hose (A) from the hydraulic system  
to the female coupling on the machine.  
Water dosage  
The water flow can be adjusted during operations with your  
thumb.  
Connect the other hydraulic coupling (B) to the male  
coupling. This hose leads oil back to the container.  
Ample water flow is needed for maximal blade life.  
CAUTION! Two hose kits can be connected when hose  
lengths exceeding 18 m are required. Do not connect more  
than two kits as the couplings cause large power loss.See the  
Technical data.  
CAUTION! The water pressure and water flow is extremely  
important for the blade’s cooling and service life. Inadequate  
cooling shortens the life of the guide rollers, drive wheel and  
the blade.  
CAUTION! Make sure that the hoses can not be loosened  
accidentally by turning the safety catches on the couplings to  
the locked position before using the machine.  
WARNING!When the machine is in operation  
the hoses are under extreme pressure. Do  
not try to connect or disconnect the hoses  
when the hydraulic system is operational.  
This can result in serious personal injuries.

MAINTENANCE  
Reconstructing the blade  
WARNING! Ring cutter blades must not be  
reconstructed. Due to its design, a ring  
cutter blade is exposed to other strains than  
a centre driven 14 inch diamond blade.  
Firstly, the drive wheel is driven on the inner  
diameter of the blade so that both the  
surfaces of the drive wheel and the blade are  
exposed to wear.The core of the blade  
becomes thinner and the guide wider, which  
prevents the blade being driven by the  
wheel. Secondly, the blade is exposed to  
loads from the rollers and from the actual  
cutting process when the blade is not held  
completely straight. Strain builds up in the  
blade until it cracks or breaks if it has been  
reconstructed. A shattered blade can cause  
serious personal injuries to the user or other  
persons. For this reason Husqvarna does  
not approve ring cutting blades that have  
been reconstructed. Contact your  
!
Husqvarna dealer for instructions.
