CUTTING BLADES

General

WARNING! A cutting blade may burst and cause injury to the operator.

A cutting blade should be checked before it is assembled on the saw and frequently during use. Look for cracks, lost segments (diamond blades) or pieces broken off. Do not use a damaged cutting blade.

Test the integrity of each new cutting blade by running it at full throttle for about 1 minute.

Only use original cutting blades designed by Husqvarna for use on this machine.

Husqvarna issues warnings and recommendations for the use and proper care of the cutting blades. Those warnings come with the cutting blades. Read and follow all instructions from Husqvarna.

• This machine is only to be used with Husqvarna´s specially developed diamond blades intended for Cutn-Break. The blades have an integrated belt pulley and are approved for freehand cutting.

• Diamond blades consist of a steel core provided with segments that contain industrial diamonds.

• Always use a sharp diamond blade.

• Ensure the blades are not cracked or damaged in any other way. Replace blades if necessary.

Diamond blades for different materials

WARNING! Never use a cutting blade for any other materials than what it was

intended to cut. Never use a diamond blade to cut plastic

material. The heat produced during cutting may melt the plastic and it can stick to the cutting blade and cause a kickback.

Cutting metal generates sparks that may cause ﬁre. Do not use the machine near ignitable substances or gases.

• Diamond blades are ideal for masonry and reinforced concrete. Ask your dealer for help in choosing the right product.

• 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.

Water cooling

WARNING! Cool diamond blades designed for wet cutting continuously with water to prevent heating, which can deform the diamond blade resulting in damage to the machine and personal injury.

• Water cooling must always be used.

• Using wet cutting blades without water can cause excessive heat build-up, resulting in poor performance, severe blade damage and is a safety hazard.

• Water cools the blade and increases its service life while also reducing the formation of dust.

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 diamond blade causes overheating, which can result in the diamond segments coming loose.

Sharpen the blades by cutting a soft material such as sandstone or brick.

Transport and storage

• Make sure the machine is secured and that the cutting blades are properly protected during the transport and storage of the machine.

• Before use inspect all blades for transport or storage damage.

ASSEMBLY

Assembly

WARNING! Always pull out the plug from the outlet socket before cleaning,

maintenance or assembly.

Assembling the blades

• Husqvarna blades are especially manufactured and approved for freehand cutting with the K 3000 Cut-nBreak. The blades have integrated belt pulley halves and are to be changed in pairs.

• Loosen the nuts and clamping bolt which release the bar. This will position the drive belt in a more favourable position with regard to assembling the new blades.

The drive belt is not clamped so easily.

• Dismantle the old blades by loosening the centre nut. Check the drive belt for wear when the blades are dismantled. When changing the drive belt see the instructions under the heading ”Replacing the drive belt”.

NOTICE! It is very important that the blades rotate when the nut is tightened. This is to ensure that the belt is not clamped between the integrated drive belt halves on the blades when the blades/drive belt are pulled together with the nut. Ideally this is done alternately, i.e. tighten a little, rotate a little and repeat until the blades are secured.

torque for the bolt holding the blade is: 15 Nm (130 in.lb).

NOTICE! Do not forget to tighten the belt and check the belt adjustment before cutting. See the instructions under the heading ”Inspecting and adjusting the drive belt”.

Protection for the blades

• The guards should always be ﬁtted on the machine. Check that the guards are properly secured and work before starting to cut.

• Position the blades on each side of the cutting arm. Make sure that the holes for both guide pins in the drive belt halves are aligned so that they correspond with the holes in the washer, and the nut too. Now ﬁt the bolt and washer unit with guide pins. Tightening

Basic working techniques

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!

Do not pull the power cutter to one side, this can cause the blade to jam or break resulting in injury to people.

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.

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. Never cut plastic materials with a diamond blade!

Cutting metal generates sparks that may cause ﬁre. Do not use the machine near ignitable substances or gases.

Water cooling

Water cooling must always be used. Dry cutting causes immediate overheating and machine and cutting blade failure with a risk of personal injury.

• 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.

• Cut in the same direction when cutting into an existing cut. Avoid cutting at an angle to the previous cut, otherwise there is a risk of the blade jamming or that the machine can ”climb in the cut” and cause a kickback.

• Always cut from top to bottom (A).

• Remove the cutter and use a crowbar to remove the material that remains between the cut (B).

At a low water pressure, for example when the water tank is used, the restrictor can be dismantled to give the correct water ﬂow.

NOTICE! It is important not to use a too high water ﬂow without throttling as the belt can then slip.

Cutting technique

• 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.

14 – English

OPERATING

• Follow the same saw cut, but further in the work piece (C), and repeat the work with the crowbar.

WARNING! When cutting vertically, always cut from the top of the cut and

down. Never cut from the bottom of the cut and up. This can cause a kickback and result in personal injury.

• Repeat this working method until the required cutting depth is achieved (D, E).

• The blade guards are designed to easily adapt to how deep in the work piece the power cutter is moved.

Smooth cutting

To enable smooth cutting, the splash guard must be adjusted.

• Release the latch.

• Slide the splash guard sideways.

• Lock the latch.

Kickback

Kickback is a sudden, rearward motion of the saw that can occur if the blades are stalled (pinched, jammed, twisted) in the so called kickback zone. Most kickbacks are small and felt as small ”jerks” in the front handle. However, kickback can be very powerful. If you are not paying attention or have a poor grip the saw can be thrown all the way back at you.

WARNING! Kickback can be very sudden and viloent, throwing the saw back at you. It can cause serious or even fatal injuries. It is vital you understand what causes kickback and how to aviod it using proper cutting techique.

WARNING! Under all circumstances avoid grinding using the side of the

blade; it will almost certainly be damaged or 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.

English – 15

OPERATING

Cause of kickback

Kickback is caused if you are cutting with the kickback zone of the blade for example when cutting ”upwards” or towards you.

General rules

• Never cut upwards or towards you so that the kickback zone becomes actively cutting.

• Always hold the machine in a ﬁrm grip with both hands. Hold it so that the thumbs and ﬁngers grip round the handles.

• Never cut from a ladder. Use a platform or scaffold if the cut is 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 blades’ lower sections suddenly stop or when the cut closes. (To avoid, see the instructions under the heading ”General rules” and ”Pinching/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.

• Keep a good balance and a ﬁrm foothold.

• When cutting vertically, always cut from the top of the cut and down.

• Always cut at maximum speed.

• Do not cut with the upper quadrant (kickback zone) of the blade. Avoid twisting or pushing the blades sideways in the cut. This can cause kickback.

• Take care when inserting the blade in an existing cut. Make certain that the cut is wide enough and that the blades are not angled in the cut. This can cause kickback.

• Stand at a comfortable distance from the work piece.

• Never cut above shoulder height.

16 – English

Check the engine speed

Use a revolution counter regularly to check the engine speed at the working temperature, at full throttle and without a load.

MAINTENANCE

Cleaning

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.

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.

6 Check the condition of the cutting blade. 7 Check and clean the cooling air openings. 8

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.

Drive belt

NOTICE! The drive belt is fully enclosed and well-protected from dust, dirt and mechanical damage when cutting.

Tensioning the drive belt

• Check the tension of the drive belt. Stick a screwdriver in the notch.

• A correctly adjusted drive belt should have about 5 mm of movement.

• Tighten the drive belt.

• Loosen the two nuts.

• Loosen the clamping bolt.

• 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.

Functional inspection

General inspection

WARNING! Never use damaged cables. They can cause serious, even fatal,
