SAFETY INSTR UCTIONS

Steps bef ore using a new power cutter.

This machine is a hydraulically operated power cutter intended for free-hand cutting. The machine should be connected to a hydraulic unit with an oil ﬂow of 35-42 litres/min and a maximum pressure of 150 bar.

• Please read the operator’s manual carefully.

• Check the cutting blade’s mounting, see the chapter ”Assembly”.

Let your Husqvarna dealer check the power cutter and make essential adjustments and repairs.

ARNING! Under no circumstances may the

design of the machine be modiﬁed without

the permission of the manufacturer. Always use genuine accessories. Non-authorized modiﬁcations and/or accessories can result in serious personal injury or the death of the operator or others.

ARNING! Use of products which cut, grind,

drill, sand or shape material can generate

dust and vapors which may contain harmful chemicals. Know the nature of the material being worked on and wear appropriate dust mask or respirator protection.

• Breathing mask

• Heavy-duty, ﬁrm grip gloves.

• Tight-ﬁtting, heavy-duty and comfortable clothing that permits full freedom of movement.

• Use leg-guards recommended for the material to be cut.

• Boots with steel toe-caps and non-slip sole

ARNING! A power cutter is a dangerous

tool if used carelessly or incorrectly and can

cause serious, even fatal injuries. It is extremely important that you read and understand the contents of this Operator’s Manual.

Husqvarna Construction Products has a policy of continuous product development. Husqvarna reserves the right to modify the design and appearance of products without prior notice and without further obligation introduce design modiﬁcations.

All information and all data in the Operator’s Manual were applicable at the time the Operator’s Manual was sent to print.

ersonal protective equipment

ARNING! You must use approved personal

protective equipment whenever you use the

machine. Personal protective equipment cannot eliminate the risk of injury but it will reduce the degree of injury if an accident does happen. Ask your dealer for help in choosing the right equipment.

Protective helmet

• Hearing protection

• Protective goggles or a visor

• Always have a ﬁrst aid kit nearby.

SAFETY INSTR UCTIONS

Switc h lock and ON/OFF valve for the water

The s witch lock is designed to prevent accidental operation of the switch. The ON/OFF valve for the water supply is also controlled with the switch lock.

When the switch lock (A) is pressed in this opens the water valve and releases the switch (B).

As long as the switch is pressed in the switch lock remains pressed in and the water valve open.

When you release your grip on the handle this resets both the switch and the switch lock. This takes place via two independent return spring systems. This position causes the machine to stop and the switch to be locked.

The water valve returns to the stop position when the handle is released.

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 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 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.

• Wear personal protective equipment. See instructions under the heading Personal protective equipment.

• Never use a machine that has been modiﬁed in any way from its original speciﬁcation.

• 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.

• Never allow anyone else to use the machine without ﬁrst ensuring that they have understood the contents of the operator’s manual.

ransport and storage

Do not store or tr ansport 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.

General w orking 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!

Basic safety rules

• Look around you:

- To ensure that people, animals or other things cannot affect your control of the machine.

- To make sure that none of the above might come into contact with the cutting equipment.

• 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.

• 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.

• Make sure that no clothes or parts of the body come in contact with the cutting equipment when it is rotating.

• Keep at a safe distance from the cutting equipment when it is rotating.

• The guard for the cutting equipment must always be on when the machine is running.

• 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.

• 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.

SAFETY INSTRUCTIONS

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

• 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.

• Move the blade slowly backwards and forwards to give a small contact surface between the blade and material to be cut. This will mean the blade temperature is kept down resulting in efﬁcient cutting.

• Feed the machine in line with the blade. Side pressure can destroy the blade and is extremely dangerous.

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.

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 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.

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

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.
