MACHINE´S SAFETY EQUIPMENT

English

–

General

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.

Throttle trigger lockout

The throttle trigger lock is designed to prevent accidental operation of the throttle. When the lock (A) is pressed in this releases the throttle (B).

The trigger lock remains pressed in as long as the throttle is pressed. When the grip on the handle is released the throttle trigger and the throttle trigger lock both return to their original positions. This is controlled by two independent return spring systems. This means that the throttle trigger is automatically locked in the idle position.

Checking the throttle lockout

• Make sure the throttle control is locked at the idle setting when the throttle lockout is released.

• Press the throttle lockout and make sure it returns to its original position when you release it.

• Check that the throttle trigger and throttle lockout move freely and that the return springs work properly.

• Start the power cutter and apply full throttle. Release the throttle control and check that the cutting blade stops and remains stationary. If the cutting blade rotates when the throttle is in the idle position you should check the carburettor’s idle adjustment. See instructions in the section "Maintenance".

Stop switch

Use the stop switch to switch off the engine.

Checking the stop switch

• Start the engine and make sure the engine stops when you move the stop switch to the stop setting.

WARNING! Never use a machine that has faulty safety equipment! If your machine fails any checks contact your service agent to get it repaired.

The engine should be switched off, and the stop switch in STOP position.

MACHINE´S SAFETY EQUIPMENT

8 – English

Blade guard

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.

Checking the blade and the blade guard

• Check that the guard over the cutting blade is not cracked or damaged in any other way. Replace when damaged.

• Check that the cutting blade is ﬁtted correctly and does not show signs of damage. A damaged cutting blade can cause personal injury.

Vibration damping system

• Your machine is equipped with a vibration damping system that is designed to minimize vibration and make operation easier.

• The machine ′ s vibration damping system reduces the transfer of vibration between the engine unit/cutting equipment and the machine ′ s handle unit. The engine body, including the cutting equipment, is insulated from the handles by vibration damping units.

Checking the vibration damping system

• Check the vibration damping units regularly for cracks or deformation. Replace them if damaged.

• Check that the vibration damping element is securely attached between the engine unit and handle unit.

Mufﬂer

The mufﬂer is designed to keep noise levels to a minimum and to direct exhaust fumes away from the user.

Inspecting the mufﬂer

Check regularly that the mufﬂer is complete and secured correctly.

WARNING! Always check that the guard is correctly ﬁtted before starting the machine.

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. Such 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. These symptoms may be increased in cold temperatures.

WARNING! The engine should be switched off, and the stop switch in STOP position.

WARNING! Never use a machine without a mufﬂer, or with a faulty mufﬂer. A damaged mufﬂer may substantially increase the noise level and the ﬁre hazard. Keep ﬁre ﬁghting equipment handy.

The mufﬂer gets very hot during and after use as well as when idling. Be aware of the ﬁre hazard, especially when working near ﬂammable substances and/ or vapours.

Keep ﬁre ﬁghting equipment handy.

CUTTING BLADES

English

–

General

• Cutting blades are available in two basic designs; abrasive blades and diamond blades.

• 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 Fitting the cutting blade.

Suitable cutting blades

For more information, see the ”Technical data” section. *Without water **Diamond blades for dry cutting only

Cutting blades for different materials

Follow the instructions supplied with the cutting blade concerning the suitability of the blade for various applications, or consult your dealer in case of doubts.

* Only specialty blades.

Hand held, high speed machines

• Many cutting blades that might ﬁt this power cutter are intended for stationary saws and have a lower speed rating than is needed for this hand-held saw. Cutting blades with a lower speed rating shall never be used on this saw.

• Husqvarna cutting blades are manufactured for highspeed, portable power cutters.

• 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.

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

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

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.

CUTTING BLADES

10 – English

Blade vibration

• The blade can become out-of-round and vibrate if an excessive feed pressure is used.

• A lower feed pressure can stop the vibration. Otherwise replace the blade.

Abrasive blades

• The cutting material on abrasive blades 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.

• A cutting blade’s performance is determined by the type and size of abrasive corn, and the type and hardness of the bonding agent.

• Ensure the cutting blade is not cracked or damaged.

• Test the abrasive blade by hanging it on your ﬁnger and tapping it lightly with a screwdriver or the like. If the blade does not produce a resonant, ringing sound it is damaged.

Abrasive blades for different materials

Rail cutting

Only use specially intended cutting blades for rail cutting.

Diamond blades

General

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

• 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.

Diamond blades for different materials

• Diamond blades are ideal for masonry, reinforced concrete and other composite materials.

• Diamond blades are available in several hardness classes.

• Special blades should be used when cutting metal. Ask your dealer for help in choosing the right product.

Sharpening diamond blades

• Always use a sharp diamond blade.

• 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 blade by cutting in a soft material such as sandstone or brick.

WARNING! Do not use abrasive blades with water. The strength is impaired when abrasive blades are exposed to water or moisture, which results in an increased risk of the blade breaking.

Blade type Material

Concrete blade

Concrete, asphalt, stone masonry, cast iron, aluminium, copper, brass, cables, rubber, plastic, etc.

Metal blade

Steel, steel alloys and other hard metals.

Blade for rail cutting Rail

WARNING! 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.

Diamond blades become very hot when used. An overheated blade is a result of improper use, and may cause deformation of the blade, resulting in damage and injuries.

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

CUTTING BLADES

English – 11

Diamond blades and cooling

• During cutting the friction in the cut causes the diamond blade to be heated up. If the blade is allowed to get too hot this can result in loss of blade tensioning or core cracking.

Diamond blades for dry cutting

• Although no water is required for cooling, dry cutting blades must be cooled with air ﬂow around the blades. For this reason dry cutting blades are recommended only for intermittent cutting. Every few seconds of cutting the blade should be allowed to run 'free” with no load to allow the air ﬂow around the blade to dissipate the heat.

Diamond blades for wet cutting

• Wet cutting diamond blades must be used with water to keep the blade core and segments cool during sawing.

• Wet cutting blades should NOT be used dry.

• 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.

Toothed blades (Rescue)

Use of this power cutter with a carbide tipped blade is a violation of work safety regulations.

Due to the hazardous nature and exigent circumstances involved with ﬁre ﬁghting and rescue operations

conducted by the various highly trained public safety forces, safety professionals (ﬁre departments), Husqvarna is aware that they may use this power cutter with carbide tipped blades in certain emergency situations due to the ability of carbide tipped blades to cut many different types of obstructions and materials in combination without having to take time to switch blades or machines. When using this power cutter be aware at all times that carbide tipped blades are more kickback prone than abrasive or diamond blades if not used properly. Carbide tipped blades can also throw pieces of material away from the blade.

For these reasons, a power cutter equipped with a carbide tipped blade should never be used except by highly trained public safety professionals who are aware of the risks associated with its use and then only in those exigent circumstances when other tools are deemed inefﬁcient and ineffective to for ﬁre or rescue operations. A power cutter equipped with carbide tipped blade should never be used to cut wood in non-rescue operations. For these applications a chainsaw or a circular saw is the proper tool.

Transport and storage

• 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.

• Store cutting blades in dry, frost free conditions. Special care should be taken with abrasive blades. Abrasive blades must be stored on a ﬂat, level surface. If an abrasive blades is stored in humid conditions, this can cause imbalance and result in injury.

• Inspect new blades for transport or storage damage.

WARNING! Never use toothed blades such as wood cutting blades, circular toothed blades, carbide tipped blades etc. The risk of kickback is signiﬁcantly increased and tips can be torn off and thrown at high speed. Carelessness can result in serious personal injury or even death.

Government regulation requires a different type of guarding for carbide tipped blades not available on power cutters – a so called 360 degree guard. Power Cutters (this saw) use Abrasive or Diamond blades and have a different guarding system which does not provide protection against the dangers presented by wood cutting blades.

ASSEMBLING AND ADJUSTMENTS

12 – English

General

Husqvarna’s blades are high speed blades approved for hand held power cutters.

Checking the spindle shaft and ﬂange washers

When the blade is replaced with a new one, check the ﬂange washers and the spindle shaft.

• Check that the threads on the spindle shaft are undamaged.

• 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 spindle shaft.

Use only ﬂange washers supplied by Husqvarna, min. diameter 105 mm/4.1".

Do not use warped, notched, indented or dirty ﬂange washers. Do not use different dimensions of ﬂange washers.

Checking the arbor bushing

The arbor bushings are used to ﬁt the machine to the centre hole in the cutting blade.

The machine is supplied with either a bushing that can be ﬂipped over to ﬁt blades with either 20 mm or 1” (25,4 mm) centre holes, or with a ﬁxed bushing. A decal on the blade guard indicates which bushing has been factory ﬁtted together with appropriate blade speciﬁcation.

• Check that the bushing on the machine's spindle shaft corresponds with the centre hole of the cutting blade. The blades are marked with the diameter of the centre hole.

Use only bushings supplied by Husqvarna. Those bushings have been designed for your power cutter.

Checking the direction of the blade rotation

• When using diamond blades make sure that it rotates in the direction indicated by the arrow on the blade. The direction of rotation for the machine is shown by arrows on the cutting arm.

Fitting the cutting blade

• The blade is placed on the bushing (A) between the inner ﬂange washer (B) and the ﬂange washer (C). The ﬂange washer is turned so that it ﬁts on the axle.

• Lock the shaft. Insert a tool in the hole in the cutting head and rotate the blade until it is locked.

• Tightening torque for the bolt holding the blade is: 25 Nm (18,5 ft-Ibs).

WARNING! The engine should be switched off, and the stop switch in STOP position.

ASSEMBLING AND ADJUSTMENTS

English – 13

Blade guard

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.

The blade guard is friction locked.

• Press the ends of the guard against the work piece or adjust the guard with the adjustment handle. The guard must always be ﬁtted on the machine.

Reversible cutting head (K 1270)

The machine is ﬁtted with a reversible cutting head allowing cutting close to a wall or at ground level, restricted only by the thickness of the blade guard.

In the event of a kickback it is harder to control the machine when cutting with the cutting head reversed. The cutting blade is further away for the centre of the machine which means the handle and the cutting blade are no longer in alignment. It is more difﬁcult to restrain the machine if the blade gets jammed or stuck in its kickback danger zone. See under the "Kickback" heading in the "Operating" section for additional information.

Some of the machine’s good ergonomic features are jeopardised such as balance. Cutting with the cutting head reversed should only occur with cuts that are not possible in a standard manner.

• First release the two bolts and then the adjuster screw to release the belt tension.

• Now unscrew the bolts and dismantle the belt guard.

• Remove the belt from the belt pulley.

• The cutting head is now loose and can be removed from the machine.

• Remove the cutting head and attach it to the other side of the cutting arm.

• Fit the belt guard to the reversed cutting head.

• Tighten the drive belt. See instructions in the section "Maintenance".

• Assemble the water hose nipple and the hose on the opposite upper side of the blade guard.

FUEL HANDLING

14 – English

General

Fuel

Petrol

• Use good quality unleaded or leaded petrol.

• The lowest octane recommended is 90 (RON). If you run the engine on a lower octane grade than 90 socalled knocking can occur. This gives rise to a high engine temperature, which can result in serious engine damage.

• When working at continuous high revs a higher octane rating is recommended.

Environment fuel

HUSQVARNA recommends the use of alkylate fuel, either Aspen two-stroke fuel or environmental fuel for four-stroke engines blended with two-stroke oil as set out below. Note that carburettor adjustment may be necessary when changing the type of fuel (see the instructions under the heading Carburettor).

Ethanol blended fuel, E10 may be used (max 10% ethanol blend). Using ethanol blends higher than E10 will create lean running condition which can cause engine damage.

Two-stroke oil

• For best results and performance use HUSQVARNA two-stroke engine oil, which is specially formulated for our air-cooled two-stroke engines.

• Never use two-stroke oil intended for water-cooled engines, sometimes referred to as outboard oil (rated TCW).

• Never use oil intended for four-stroke engines.

Mixing

• Always mix the petrol and oil in a clean container intended for fuel.

• Always start by ﬁlling half the amount of the petrol to be used. Then add the entire amount of oil. Mix (shake) the fuel mixture. Add the remaining amount of petrol.

• Mix (shake) the fuel mixture thoroughly before ﬁlling the machine’s fuel tank.

• Do not mix more than one month’s supply of fuel at a time.

Mixing ratio

• 1:50 (2%) with HUSQVARNA two-stroke oil or equivalent.

• 1:33 (3%) with oils class JASO FB or ISO EGB formulated for air-cooled, two-stroke engines or mix as per recommendation from the oil manufacturer.

WARNING! Running an engine in a conﬁned or badly ventilated area can result in death due to asphyxiation or carbon monoxide poisoning. Use fans to ensure proper air circulation when working in trenches or ditches deeper than one meter.

Fuel and fuel fumes are ﬂammable and can cause serious injury when inhaled or allowed to come in contact with the skin. For this reason observe caution when handling fuel and make sure there is adequate ventilation.

The exhaust fumes from the engine are hot and may contain sparks which can start a ﬁre. Never start the machine indoors or near combustible material!

Do not smoke and do not place any hot objects in the vicinity of fuel.

NOTICE! The machine is equipped with a two-stroke engine and must always be run using a mixture of petrol and two-stroke oil. It is important to accurately measure the amount of oil to be mixed to ensure that the correct mixture is obtained. When mixing small amounts of fuel, even small inaccuracies can drastically affect the ratio of the mixture.

FUEL HANDLING

English – 15

Fueling

Never start the machine:

• If you have spilled fuel or engine oil on the machine. Wipe off the spill and allow the remaining fuel to evaporate.

• If you have spilled fuel on yourself or your clothes, change your clothes. Wash any part of your body that has come in contact with fuel. Use soap and water.

• If the machine is leaking fuel. Check regularly for leaks from the fuel cap and fuel lines.

• Unless the fuel cap is securely tightened after refueling.

Transport and storage

• Store and transport the machine and fuel so that there is no risk of any leakage or fumes coming into contact with sparks or open ﬂames, for example, from electrical machinery, electric motors, electrical relays/ switches or boilers.

• When storing and transporting fuel always use approved containers intended for this purpose.

Long-term storage

• When storing the machine for long periods the fuel tank must be emptied. Contact your local petrol station to ﬁnd out where to dispose of excess fuel.

WARNING! Taking the following precautions, will lessen the risk of ﬁre:

Do not smoke and do not place any hot objects in the vicinity of fuel.

Always stop the engine and let it cool for a few minutes before refuelling. The engine should be switched off, and the stop switch in STOP position.

When refuelling, open the fuel cap slowly so that any excess pressure is released gently.

Clean the area around the fuel cap.

Tighten the fuel cap carefully after refuelling.

If the cap is not properly tightened the cap might vibrate lose and fuel may escape from the fuel tank creating a ﬁre hazard.

Move the machine at least 3 m from the refuelling point before starting it.

Work area safety

• Observe your surroundings to ensure that nothing can affect your control of the machine.

• Ensure that no one/nothing can come into contact with the cutting equipment or be hit by parts thrown by the blade.

• Do not use the machine in bad weather, such as dense fog, heavy 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 machine 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 injury to the operator.Take great care when working on sloping ground.

• Ensure that the working area is sufﬁciently illuminated to create a safe working environment.

• Make sure that no pipes or electrical cables are routed in the working area or in the material to be cut.

• If cutting into a container (drum, pipe, or other container) you must ﬁrst make sure it does not contain ﬂammable or other volatile material.

Basic working techniques

• The machine is designed and intended for cutting with abrasive blades or diamond blades intended for high speed handheld machines. The machine shall not be used with any other type of blade, or for any other type of cutting.

• Check that the cutting blade is ﬁtted correctly and does not show signs of damage. See the instructions in the sections "Cutting blades" and "Assembly and adjustments".

• Check that the correct cutting blade is used for the application in question. See instructions in the section "Cutting blades".

• Never cut asbestos materials!

• Hold the saw with both hands; keep a ﬁrm grip with thumbs and ﬁngers encircling the handles. The right hand should be on the rear handle and the left hand on the front handle. All operators, weather right or left handed shall use this grip. Never operate a power cutter holding it with only one hand.

WARNING! Unauthorized modiﬁcations and/or accessories may lead to serious injury or death to the user or others. Under no circumstances may the design of the machine be modiﬁed without the permission of the manufacturer.

Do not modify this product or use it if it appears to have been modiﬁed by others.

Never use a machine that is faulty. Carry out the safety 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 Maintenance heading.

Always use genuine accessories.

WARNING! This machine produces an electromagnetic ﬁeld during operation. This ﬁeld may under some circumstances interfere with active or passive medical implants. To reduce the risk of serious or fatal injury, we recommend persons with medical implants to consult their physician and the medical implant manufacturer before operating this machine.

WARNING! The safety distance for the power cutter is 15 metres (50 foot). 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 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 or break and can cause immense damage. Only use the cutting section.

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.

OPERATING

18 – English

• Stand parallel to the cutting blade. Avoid standing straight behind. In the event of a kickback the saw will move in the plane of the cutting blade.

• Maintain a safe distance from the cutting blade when the engine is running.

• Never leave the machine unsupervised with the motor running.

• Never move the machine when the cutting equipment is rotating.

• 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. The guards for the cutting equipment must always be ﬁtted when the machine is running.

• Never use the kickback zone of the blade for cutting. See instructions under the heading "Kickback".

• Keep a good balance and a ﬁrm foothold.

• Never cut above shoulder height.

• Never cut from a ladder. Use a platform or scaffold if the cut is above shoulder height. Do not overreach

• Stand at a comfortable distance from the work piece.

• Check that the blade is not in contact with anything when the machine is started

• Apply the cutting blade gently with high rotating speed (full throttle) Maintain full speed until cutting is complete.

• Let the machine work without forcing or pressing the blade.

• Feed down the machine in line with the blade. Pressure from the side can damage the blade and is very dangerous.

• 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.

Managing dust (Applies only for K 1270)

The machine is ﬁtted with a low ﬂushing water kit that offers maximum dust suppression.

Use wet cutting blades with water cooling when possible for optimal dust management. See instructions in the section "Cutting blades".

Adjust water ﬂow using the tap to bind the cutting dust. The volume of water required varies depending on the type of job at hand.

If water hoses loosen from their supply sources, this indicates that the machine is connected to a water pressure that is too high. See instructions under the "Technical data" heading for recommended water pressure.

Rail cutting

General

Assembling the rail ﬁxture

• Mount the rail ﬁxture onto the rail. Screw the lock handle tight.

• Mount the power cutter with its right side to the ﬁxture. The mounting on the power cutter is ﬁtted closest to the spindle on the cutting blade when assembling from this side. Assembly should therefore be carried out primarily from this direction.

Cutting guide

The cutting guide is used to facilitate guiding the blade to where the cut is to be made. The ﬁrst time you use the power cutter, you must cut the guide.

• Fold out the cutting guide.

• Fix the cutting guide parallel to the rail in an appropriate manner.

• Carefully cut off the guide.

Work procedure

• Fold out the cutting guide.

• Align the saw cut and fold in the guide.

• Begin the cutting process by swinging the machine back and forth horizontally. This way the cutting blade’s contact surface to the rail is minimised, which reduces the risk of the blade glazing.

• When you have cut through the head (A), you continue cutting the rib (B) and foot (C).

If the cut cannot be completed from one side, the power cutter must be turned around.

• Shut off the machine.

• Dismantle the power cutter from the ﬁxture.

NOTICE! The rail ﬁxture must not be mounted on the machine during transport or when handling the equipment.

The rail ﬁxture is a precision tool that can be damaged if not handled with care which results in less precise cuts.

NOTICE! The rail ﬁxture must be ﬁrst ﬁtted to the rail before the power cutter is ﬁtted to the rail ﬁxture. This is done to guarantee that the ﬁxture is attached at right angles to the rail.

B C

OPERATING

20 – English

• Fit the power cutter with its left side to the rail ﬁxture.

• Guide the cutting blade down towards the rail and check that the cutting blade is centred in the cut. If necessary, adjust the movable bushing so that the blade ends up centred in the middle of the cut.

• Now cutting can proceed.

• When the cut is completed, ﬁrst dismantle the power cutter from the rail ﬁxture. Secondly, dismantle the rail ﬁxture from the rail and store the ﬁxture and the machine separately in the supplied plywood box.

General tips

• Only use specially intended cutting blades for rail cutting.

• Apply full throttle until the blade reaches top speed. Reduce throttle to drop below the speed limitation which reduces cutting blade vibrations when initiating a cut to thereby produce straighter cuts. Apply full throttle and maintain full speed until the cutting process is completed.

• Hold the machine’s handle so that the hands are in line with the cutting blade. This to achieve maximum cutting speed, blade service life and a straight cut.

• Mount the power cutter primarily with its right side to the ﬁxture, for the best chance of producing a straight cut.

• When performing the cutting process correctly, it takes about one minute to cut a 50 kg/m-rail and about one and a half minute to cut 60 kg/m-rail. If it takes longer, review your cutting technique. Problems which arise are often the result of incorrect cutting technique or poor cutting blades.

Kickback

Kickback is the sudden upward motion that can occur if the blade is pinched or stalled in the kickback zone. Most kickbacks are small and pose little danger. However a kickback can also be very violent and throw the power cutter up and back towards the user in a rotating motion causing serious or even fatal injury.

Reactive force

A reactive force is always present when cutting. The force pulls the machine in the opposite direction to the blade rotation. Most of the time this force is insigniﬁcant. If the blade is pinched or stalled the reactive force will be strong and you might not be able to control the power cutter.

Never move the machine when the cutting equipment is rotating. Gyroscopic forces can obstruct the intended movement.

WARNING! Kickbacks are sudden and can be very violent. The power cutter can be thrown up and back towards the user in a rotating motion causing serious or even fatal injury. It is vital to understand what causes kickback and how to avoid it before using the machine.

OPERATING

English – 21

Kickback zone

Never use the kickback zone of the blade for cutting. If the blade is pinched or stalled in the kickback zone, the reactive force will push the power cutter up and back towards the user in a rotating motion causing serious or even fatal injury.

Climbing kickback

If the kickback zone is used for cutting the reactive force drives the blade to climb up in the cut. Do not use the kickback zone. Use the lower quadrant of the blade to avoid climbing kickback.

Pinching kickback

Pinching is when the cut closes and pinches the blade. If the blade is pinched or stalled the reactive force will be strong and you might not be able to control the power cutter.

If the blade is pinched or stalled in the kickback zone, the reactive force will push the power cutter up and back towards the user in a rotating motion causing serious or even fatal injury. Be alert for potential movement of the work piece. If the work piece is not properly supported and shifts as you cut, it might pinch the blade and cause a kick back.

Pipe cutting

Special care should be taken when cutting in pipes. If the pipe is not properly supported and the cut kept open through out the cutting, the blade might be pinched in the kickback zone and cause a severe kickback. Be especially alert when cutting a pipe with a belled end or a pipe in a trench that, if not properly supported, may sag and pinch the blade.

Before starting the cut the pipe must be secure so it does not move or roll during cutting.

If the pipe is allowed to sag and close the cut, the blade will be pinched in the kick back zone and a severe kick back might develop. If the pipe is properly supported the end of the pipe will move downward, the cut will open and no pinching will occur.

Proper sequence cutting a pipe

1 First cut section I. 2 Move to side II and cut from section I to bottom of the

pipe.

3 Move to side III and cut the remaining part of the pipe

ending at the bottom.

How to aviod kickback

Avoiding kickback is simple.

• The work piece must always be supported so that the cut stays open when cutting through. When the cut opens there is no kickback. If the cut closes and pinches the blade there is always a risk of kickback.

• Take care when inserting the blade in an existing cut.

• 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.

• Start throttle position and choke is obtained by pulling out the choke control completely.

• Decompression valve: Press in the valve to reduce the pressure in the cylinder, this is to assist starting the power cutter. The decompression valve should always be used when starting. The valve

automatically returns to its initial position when the machine starts.

• Grip the front handle with your left hand. Put your right foot on the lower section of the rear handle pressing the machine against the ground. Pull the starter handle with your right hand until the engine starts.

Never twist the starter cord around your hand.

• The machine stops when the engine ﬁres because the choke control is pulled out.

• Press the choke control and the decompression valve.

• Pull the starter handle until the engine starts.

• When the machine starts, press the throttle trigger to disengage the start throttle, and the machine will idle.

WARNING! Note the following before starting: Please read the operator’s manual carefully and make sure you understand the instructions before using the machine.

Wear personal protective equipment. See under heading ”Personal protective equipment”.

Do not start the machine without the belt and belt guard ﬁtted. Otherwise the clutch could come loose and cause personal injuries.

Check that the fuel cap is properly secured, and that there is no fuel leakage.

Make sure no unauthorised persons are in the working area, otherwise there is a risk of serious personal injury.

WARNING! The cutting blade rotates when the engine is started. Make sure it can rotate freely.

NOTICE! Pull with your right hand out the starter cord slowly until you feel a resistance (as the starter pawls engage) and then pull ﬁrmly and rapidly.

Do not pull the starter cord all the way out and do not let go of the starter handle when the cord is fully extended. This can damage the machine.

STARTING AND STOPPING

24 – English

With a warm engine:

• Make sure that the stop switch (STOP) is in the left position.

• The correct choke/start throttle setting is obtained by pulling the choke control to the choke position and then pushing it in again. This only engages the start throttle setting without any choke.

• Decompression valve: Press in the valve to reduce the pressure in the cylinder, this is to assist starting the power cutter. The decompression valve should always be used when starting. The valve automatically returns to its initial position when the machine starts.

Never twist the starter cord around your hand.

• When the machine starts, press the throttle trigger to disengage the start throttle, and the machine will idle.

Stopping

• Stop the engine by moving the stop switch (STOP) to the right.

NOTICE! Pull with your right hand out the starter cord slowly until you feel a resistance (as the starter pawls engage) and then pull ﬁrmly and rapidly.

Do not pull the starter cord all the way out and do not let go of the starter handle when the cord is fully extended. This can damage the machine.

WARNING! When the engine is running the exhaust contains chemicals such as unburned hydrocarbons and carbon monoxide. The content of the exhaust fumes is known to cause respiratory problems, cancer, birth defects or other reproductive har

Carbon monoxide is colorless and tasteless and is always present in exhaust fumes. The onset of carbon monoxide poisoning is distinguished by a slight dizziness which may or may not be recognized by the victim. A person may collapse and lapse into unconsciousness with no warning if the concentration of carbon monoxide is sufﬁciently high. Since carbon monoxide is colorless and odorless, its presence can not be detected. Any time exhaust odors are noticed, carbon monoxide is present. Never use a petrol powered power cutter indoors or in trenches more than 3 foot (1 meter) deep or in other areas with poor ventilation. Ensure proper ventilation when working in trenches or other conﬁned areas.

CAUTION! The cutting blade continues to rotate up to a minute after the motor has stopped. (Blade coasting.) Make sure that the cutting blade can rotate freely until it is completely stopped. Carelessness can result in serious personal injury.
