Machine ′s safety equipment

This section describes the machine′s safety equipment, its purpose, and how checks and maintenance should be carried out to ensure that it operates correctly. See the ”What is what?” section to locate where this equipment is positioned on your machine.

WARNING! Never use a machine that has faulty safety equipment! Carry out the
inspection, maintenance and service routines listed in this section.

Switch

The switch is used to start and stop the machine.

Switch lock and ON/OFF valve for the water

The switch 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.

Blade guard

This guard is fitted above the blade and is designed to prevent parts of the blade or cutting fragments from being thrown towards the user.

Checking, maintaining and servicing the machine′s safety equipment

WARNING! All servicing and repair work on the machine requires special training. This is especially true of the machine′s safety equipment. If your machine fails any of the checks described below you must contact your service agent. When you buy any of our products we guarantee the availability of

General working 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 within reach of your saw or be injured by falling trees.
• 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.

Cutting

WARNING! The safety distance for the power cutter is 15 meters. 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.

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 color 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.
• 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.
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.

Large work

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.

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.

CAUTION! If the upper horizontal cut is made before the lower horizontal cut, the work piece will fall on the blade and jam it.

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

• 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.

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.

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.

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.

Vibrations on diamond blades

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.
