SAFETY PRECAUTIONS

General precautions

-The operator MUST read this instruction manual to ensure safe operation (even if you already have experience in using cutoff saws). It is important to be familiar with the operation of this particular cutoff saw. Users insufficiently informed will endanger themselves as well as others due to improper handling.

-Let only persons who have experience in using cutoff saws work with this unit. When letting another person use the Power Cut, this instruction manual must be provided along with it.

-First-time operators should ask a specialist to instruct them in working with gasoline-powered cutoff saws.

-Children and persons under 18 years of age must not be allowed to use this Power Cut. Persons over the age of 16 years may, however, use the Power Cut for the purpose of being trained as long as they are under the supervision of a qualified trainer.

-Working with the Power Cut requires high concentration.

-Operate the Power Cut only if you are in good physical condition. If you are tired, your attention will be reduced. Be especially careful at the end of a working day. Perform all work calmly and carefully. The user has to accept liability for others.

-Never work while under the influence of alcohol, drugs, medication or other substances which may impair vision, dexterity or judgement.

-A fire extinguisher must be available in the immediate vicinity when working in easily inflammable vegetation or when it has not rained for a long time (danger of fire).

-Asbestos and other materials that can release toxins may be cut only with the necessary safety precautions and after notification of the proper authorities and under their supervision or that of a person appointed by them.

Protective equipment

-In order to avoid head, eye, hand or foot injuries as well as to protect your hearing the following protective equipment must be used during operation of the Power Cut:

-The kind of clothing should be appropriate, i. e. it should be tight-fitting but not be a hindrance. Clothing in which grains of material can accumulate (trousers with cuffs, jackets and trousers with wide-open pockets, etc.) must not be worn, particularly when cutting metal.

-Do not wear any jewellery or clothing that can get caught or distract from the operation of the Power Cut.

-It is necessary to wear a protective helmet whenever working with the Power Cut. The protective helmet (A) is to be checked in regular intervals for damage and is to be replaced after 5 years at the latest. Use only approved protective helmets.

-The helmet visor (B) protects the face from dust and material grains. In order to prevent injuries to eyes and face, always wear protective goggles (C) or visor when using the Power Cut.

-To prevent hearing damage, always wear suitable personal hearing protection. (ear muffs (D), ear plugs, etc.). Octave brand analysis upon request.

-When dry-cutting dust-producing materials such as stone or concrete, always wear approved respiratory protection (E).

-Work gloves (F) of tough leather are part of the required work kit of the Power Cut and must always be worn when working with the Power Cut.

-Always wear safety shoes or boots (G) with steel toes, non-skid soles, and leg protectors when working with the Power Cut. Safety shoes equipped with a protective layer provide protection against cuts and ensure a secure footing.

-Always wear a work suit (H) of sturdy material.

Fuels / Refuelling

-Go to a safe, level place before refuelling. Never refuel while on scaffolding, on heaps of material, or in similar places!

-Switch off the engine before refuelling the Power Cut.

-Do not smoke or work near open fires (6).

-Let the engine cool down before refuelling.

-Fuels can contain substances similar to solvents. Eyes and skin should not come in contact with mineral oil products. Always wear protective gloves when refuelling (not the regular work gloves!). Frequently clean and change protective clothes. Do not breathe in fuel vapors. Inhalation of fuel vapours can be hazardous to your health.

-Do not spill fuel. If a spill occurs, clean off the Power Cut immediately. Fuel should not come in contact with clothes. If your clothes have come in contact with fuel, change them at once.

-Ensure that no fuel is spilled into the soil (environmental protection). Use an appropriate surface.

-Refuelling is not allowed in closed rooms. Fuel vapors will accumulate near the floor (explosion hazard).

-Ensure to firmly tighten the screw cap of the fuel tank.

-Before starting the engine, move to a location at least 3 meters (approx. 10 feet) from where you fuelled the Power Cut (7), but not within the extended swing range of the cutting disc (direction of sparks).

-Fuel cannot be stored for an unlimited period of time. Buy only as much as will be consumed in the near future.

-When making up the gasoline/oil mixture, always put the oil in the mixing container first, and then the gasoline.

-Use only approved and marked containers for the transport and storage of fuel.

-Keep fuel away from children!

Putting into operation

-Do not work on your own. There must be someone around in case of an emergency (within shouting distance).

-Observe all anti-noise regulations when working in residential areas.

-Never use the Power Cut near inflammable materials or explosive gases! The Power Cut can create sparks leading to fire or explosion!

-Make sure that all persons within 30 meters (100 feet), such as other workers, are wearing protective gear (see "Protective Equipment") (8). Children and other unauthorized persons must remain more than 30 meters (100 feet) away from the working area. Keep an eye out for animals as well (9).

-Before starting work the Power Cut must be checked for perfect function and operating safety according to the prescriptions.

In particular, make sure that the cutting wheel is in good condition(replace immediately if torn, damaged or bent), the cutting wheel is properly mounted, the protective hood is locked in place, the hand guard is properly mounted, the V-belt has the proper tension, the throttle moves easily and the half-throttle lock button functions properly, the grips are clean and dry, and the combination switch functions properly.

-Start the Power Cut only after complete assembly and inspection. Never use the Power Cut when it is not completely assembled.

Cutoff discs

-The protection hood must always be on! Change discs only with the engine off!

-There are two basic types of cutoff discs:

-For metal (hot cutting)

-For masonry (cold cutting)

NOTE:

When using diamond cutoff discs, always make sure to observe the "direction of rotation" markings. Diamond discs should only be used for cutting masonry/brick/ concrete etc.

-Cutoff discs are intended only for radial loading, i.e. for cutting. Do not grind with the sides of the cutting disk! This will break the disk! (10)!

Caution!

Never change direction (turning radius less than 5 meters / 16 feet), exert lateral (sideways) pressure, or tip the Power Cut during cutting (11)!

-Use a cutting disc only for cutting the materials it is intended for. The proper type of disc must be used, for either metals or masonry.

-The arbour hole (bore) of the cutting disc must fit the shaft exactly. If the arbour hole is larger than the shaft diameter, a spacer ring must be used.

-Use only cutting wheels approved by the DSA (German Abrasive Disc Committee) or equivalent organisation for freehand cutting at up to 4370 RPM (= 80 m/sec. at circumference) for 14"/350 mm discs, or up to 5100 RPM (= 80 m/sec. at circumference) for 12"/300 mm discs.

-The disc must be free of defects (12). Do not use defective cutting discs.

Always tighten the cutting disc mounting bolt to a torque of 30 Nm. Otherwise, the cutting disc can twist.

-Before starting the cutting disc, make sure you have a steady footing.

-Put the Power Cut into operation only as described in this instruction manual (13). Always place your left foot in the rear handle and grasp the other handle firmly (with thumb and fingers). Other starting methods are not allowed.

-When starting the Power Cut it must be well supported and securely held. The cutting disc must not be touching anything.

-If the cutting disc is new, test it by running it at least 60 seconds at top speed. When doing this, make sure that no persons or body parts are in the extended swing range of the disc, in case it is defective and flies apart.

-When working with the Power Cut always hold it with both hands. Take the back handle with the right hand and the tubular handle with the left hand. Hold the handles tightly with your thumbs facing your fingers.

-CAUTION: When you release the throttle lever the disc will keep spinning for a short period of time (free-wheeling effect).

-Continuously ensure that you have a safe footing.

-Hold the Power Cut such that you will not breathe in the exhaust gas. Do not work in closed rooms or in deep holes or ditches (danger of poisoning by fumes).

-Switch off the Power Cut immediately if you observe any changes in its operating behavior.

-Switch off the engine before inspecting the V-belt tension or tightening it, replacing the cutting wheel, repositioning the cutter attachment (side or middle position) or eliminating faults (14).

-Turn off the engine immediately and check the disc if you hear or feel any change in cutting behaviour.

-Turn off the Power Cut when taking a break or stopping work (14). Place the unit in such a way that the disc is not touching anything and cannot endanger anyone.

-Do not put the overheated Power Cut in dry grass or on any inflammable objects. The muffler is very hot (danger of fire).

-IMPORTANT: After wet cutting, first turn off the water feed and then let the disc run at least 30 seconds, to fling off the remaining water and prevent corrosion.

Kickback and lock-in

-When working with the Power Cut there is a danger of kickback and lock-in.

-Kickback occurs when the top of the cutting disc is used for cutting (15).

-This causes the Power Cut to be thrown back toward the user with great force and out of control. Risk of injury!

To prevent kickback, observe the following:

-Never cut with the section of the cutting disc shown in figure 15.

Be especially careful when reinserting the disc into cuts that have already been started!

-Lock-in occurs when the cut narrows (crack, or workpiece under stress).

-This causes the Power Cut to suddenly jump forward, out of control and with great force. Risk of injury!

To prevent lock-in, observe the following:

-When reinserting the disc into previous cuts, have the Power Cut running at top speed. Always cut at top speed.

-Always support the workpiece so that the cut is under tension (16), so that the cut does not press together and jam the cutting disc as it proceeds through the material.

-When starting a cut, apply the disc to the workpiece with care. Do not just shove it into the material.

-Never cut more than one piece at a time! When cutting, make sure that no other workpiece comes into contact.

Working behavior / Method of working

-Before starting work, check the work area for any hazards (electrical wires, inflammable substances). Clearly mark the work area (for example with warning signs or by cordoning off the area).

-When working with the Power Cut hold it firmly by the front and rear handles. Never leave the Power Cut unattended!

-Whenever possible run the Power Cut at the rated arbour speed (see ”Technical Data”).

-Only use the Power Cut during good light and visibility periods. Be aware of slippery or wet areas, and of ice and snow (risk of slipping).

-Never work on unstable surfaces. Make sure that there are no obstacles in the working area, risk of stumbling. Always ensure that you have a safe footing.

-Never cut above your shoulder height (17).

-Never stand on a ladder to cut (17).

-Never use the Power Cut while standing on scaffolding.

-Do not lean over too far when working. When putting down and picking up the Power Cut, do not bend over from the waist, but instead bend in the knees. Save your back!

-Guide the Power Cut in such a way that no part of your body is within the extended swing range of the disc (18).

-Use cutting discs only for the materials for which they are designed!

-Use cutting discs only for the materials for which they are designed. Do not use the Power Cut to lift up and shovel away pieces of material and other objects.

Important! Before cutting, remove all foreign objects, such as rocks, gravel, nails etc. from the cutting area. Otherwise, such objects can be flung away by the disc with great speed. Injury hazard!

-When cutting workpieces down to length use a firm support. If necessary, secure the workpiece from slipping, but do not steady it with your foot or allow another person to hold it.

-When cutting round items, always secure them against rotation.

-When guiding the Power Cut by hand, use the side mounting position of the cutter attachment only when actually necessary. Otherwise, always use the central position. This gives the unit a better balance, for reduced operator fatigue.

Cutting metals

IMPORTANT!

Always wear approved respiratory protection!

Materials that can release toxic substances may be cut only after notifying the proper authorities and under their supervision or that of a person appointed by them.

CAUTION!

The rapid rotation of the cutting disc heats metal and melts it at the point of contact. Swing the guard as far down as possible behind the cut (19) in order to direct the stream of sparks forward, away from the operator (fire hazard).

-Determine the direction of cutting, mark the cut and apply the disc to the material at moderate speed, to cut a guide groove before going to top speed and applying more pressure to the Power Cut.

-Keep the disc straight and vertical. Do not tip it, as this can break it.

-The best way to get a good, clean cut is to pull or move the Power Cut back and forth. Do not simply press the disc into the material.

-Thick round stock is best cut in stages (20).

-Thin tubing and pipes can be cut with a simple downward cut.

-Cut large-diameter pipes as for round stock. To prevent tipping and for better control, do not let the disc sink too deeply into the material. Instead, always cut shallow around the whole piece.

-Worn discs have a smaller diameter than new discs, so that at the same engine speed they have a lower effective circumferential speed and therefore do not cut as well.

-Cut I-beams and L-bars in steps; see Figure 21.

-Cut bands and plates like pipes: along the wide side with a long cut.

-When cutting material under stress (supported material or material in structures), always make a notch in the thrust (pressure) side, and then cut from the tension side, so that the disc does not lock in. Secure cutoff material from falling!

CAUTION!

If there is a chance that the material is under stress, be prepared for it to kick back. Make sure you can get out of the way if you have to!

Be particularly careful in scrap-metal yards, junkyards, at accident sites, and with haphazard piles of material. Precariously balanced pieces or pieces under stress can act in unpredictable ways, and may slide, jump out, or burst. Secure cutoff material from falling! Always exercise extreme caution and use only equipment that is in perfect working order.

Observe the accident-prevention rules and regulations of your employer and/or insurance organization.

Cutting masonry and concrete

IMPORTANT!

Always wear approved respiratory protection!

Asbestos and other materials that can release toxic substances may be cut only after notifying the proper authorities and under their supervision or that of a person appointed by them. When cutting prestressed and reinforced concrete piles, follow the instructions and standards of the responsible authorities or the builder of the structural member. Reinforcement rods must be cut in the prescribed sequence and in accordance with applicable safety regulations.

NOTE:

Mortar, stone, and concrete develop large quantities of dust during cutting. To increase the lifetime of the cutting disc (by cooling), to improve visibility, and to avoid excessive dust creation, we strongly recommend wet cutting instead of dry cutting.

19

20

21

8

In wet cutting, the disc is wetted at an equal rate on both sides by a trickle of water. MAKITA offers the right accessories for all wet cutting applications (see also "SPECIAL ACCESSORIES").

-Remove foreign objects such as sand, stones and nails found within the working area. Caution: Watch out for electric wires and cables!

The rapid rotation of the cutting disc at the point of contact throws fragments out of the cut groove at high speed. For your safety, swing the protection hood down as far as possible behind the cut (23), so that material fragments are thrown forward, away from the operator.

-Mark the cut, and then make a groove about 5 mm (just under 1/5") along the entire length of the planned cut. This groove will then guide the Power Cut accurately guring the actual cutoff.

NOTE:

For long, straight cuts we recommend using a cart (24, see also "SPECIAL ACCESSORIES"). This makes it much easier to guide the unit straight.

-Perform the cut with a steady back-and-forth motion.

-When cutting slabs to size, you need not cut through the entire material thickness (creating unnecessary dust). Instead, simply make a shallow groove, and then knock off the excess material cleanly on a flat surface (25).

CAREFUL!

When cutting into lengths, cutting through material, making cutouts, etc., always make sure to plan the direction and sequence of cuts in such a way that the disc does not get jammed by the cut-off piece, and that no persons can be injured by falling pieces.

Transport and storage

-Always turn off the Power Cut when transporting it or moving it from place to place on a site (26).

-Never carry or move the unit with the engine on or the disc moving!

-Carry the unit only by the tubular (middle) handle with the cutting disc pointing behind you (26). Avoid touching the exhaust muffler (burn hazard!)

-When moving the Power Cut over longer distances, use a wheelbarrow or wagon.

-When transporting the Power Cut in a vehicle, make sure it is securely positioned in such a way that no fuel can leak out. Always remove the cutting disc before transporting the unit in a vehicle.

-The Power Cut should be stored safely in a dry place. It must not be left outdoors! Always dismount the cutting disc before storage. Keep the Power Cut away from children.

-Before long-term storage and before shipping the Power Cut, follow the instructions in the chapter on "Periodic care and maintenance". ALWAYS empty the fuel tank and run the carburetor dry.

-When putting cutting discs in storage, be careful to:

-Clean and dry them well.

-Store them lying down flat.

-Avoid dampness, freezing temperatures, direct sunshine, high temperatures and temperature fluctuations, as these can cause breakage and splintering.

-Always check new cutting discs or cutting discs that have been in storage to make sure that they are free of defects.

Maintenance

-Before performing maintenance work switch off the Power Cut (27) and pull out the plug cap.

-Always check the Power Cut before using it to make sure that it is in good working order. In particular, make sure that the cutting disc is properly mounted. Make sure that the cutting wheel is undamaged and suitable for the job it will be used for.

-Operate the Power Cut only at a low noise and emission level. For this ensure the carburetor is adjusted correctly.

-Clean the Power Cut regularly.

-Check the fuel tank cap regularly for good sealing.

Observe the accident prevention instructions issued by trade associations and insurance companies. NEVER make any modifications to the Power Cut! You will only be putting your own safety at risk!

Perform only the maintenance and repair works described in the instruction manual. All other work must be carried out by MAKITA Service.

Use only original MAKITA spares and accessories.

The use of non-MAKITA spares, accessories, or cutting discs increases the risk of accident. We cannot accept any responsibility for accidents or damage occurring in association with the use of cutting discs or accessories other than original MAKITA.

Fuels

Caution:

The Power Cut uses mineral-oil products (gasoline and oil).

Be especially careful when handling gasoline.

Do not smoke. Do not allow gasoline to come near flames, sparks or fire (explosion hazard).

Fuel mixture

The Power Cut is powered by a high-performance two-stroke engine. It runs on a mixture of gasoline and two-stroke engine oil.

The engine is designed for unleaded regular gasoline with a min. octane value of 91 ROZ. In case no such fuel is available, you can use fuel with a higher octane value. This will not affect the engine.

In order to obtain an optimum engine output and to protect your health and the environment use unleaded fuel only. Gasoline which contens alcohol should not used in MAKITA products.

To lubricate the engine, use a two-stroke engine oil (quality grade TC-3), which is added to the fuel. The engine is designed for the use of MAKITA HP 100 high-performance two-stroke engine oil at a mixture ratio of only 100:1 to protect the environment. In addition, this ensures a long service life and reliable operation with minimum exhaust emissions.

1 l Best.-Nr. 980 008 607

100 ml Best.-Nr. 980 008 606

NOTE: For preparing the fuel-oil mixture first mix the entire oil quantity with half of the fuel required, then add the remaining fuel. Shake the finished mixture thoroughly before pouring it into the Power Cut tank.

Caution: Open the tank cap carefully, as pressure might have built up inside!

It is not wise to add more engine oil than specified to ensure safe operation. This will only result in a higher production of combus-tion residues which will pollute the environment and clog the exhaust channel in the cylinder as well as the muffler. In addition, fuel consump-

tion will rise and performance will decrease.

Fuel storage

Fuels have only a limited shelf-life. Buy only as much as you will use in 4 weeks.

Store fuel only in approved and marked containers.

AVOID SKIN AND EYE CONTACT

Mineral oil products degrease your skin. If your skin comes in contact with these substances repeatedly and for an extended period of time, it will desiccate. Various skin deseases may result. In addition, allergic reactions are known to occur. Eyes can be irritated by contact with oil. If oil comes into your eyes, immediately wash them with clear water.

If your eyes are still irritated, see a doctor immediately!

SPECIAL ACCESSORIES

Diamond cutting discs (1)

MAKITA diamond cutting discs meet the highest demands in working safety, ease of operation, and economical cutting performance. They can be used for cutting all materials except metal.

The high durability of the diamond grains ensures low wear and thereby a very long service life with almost no change in disc diameter over the lifetime of the disc. This gives consistent cutting performance and thus high economy. The outstanding cutting qualities of the discs make cutting easier.

The diamond discs give highly concentric running for minimal vibration during use.

The use of diamond cutting discs reduces cutting time significantly. This in turn leads to lower operating costs (fuel consumption, wear on parts, repairs, and last but not least environmental damage).

Guide cart (2)

The MAKITA guide cart makes it much easier to do straight cuts, while simultaneously enabling almost untiring working. It can be adjusted for the operator´s height, and can be operated with the cutting attachment mounted in the middle or on the side.

For easier refuelling when using the cart, we recommend adding an angled tank filler neck (3).

A depth limiter can be added for still easier and more accurate cutting. It makes it possible to maintain a precise predetermined cut depth (4).

To keep down dust and for better cutting-disc cooling, MAKITA offers several options for wetting the disc during operation.

1

6

3

Water tank (5)

The water tank is designed to be mounted on the guide cart. Its high capacity makes it especially suitable for situations involving frequent site changes. For filling or for fast changing to reserve tanks, the tank can be simply lifted off the cart.

The water tank comes with all necessary connections and hoses. Mounting to the cart and Power Cut are very fast and simple.

Mains/pressure water system (6)

The mains/pressure water system is designed to be mounted on the Power Cut. It can be used with or without the cart, but is especially suitable for applications involving hand-held, stationary cutting. The water line has a fast-release connection, and can be fed either from a mains supply or from a pressure tank (7).

The water system comes with all necessary connections and lines. It can be quickly and easily mounted on the Power Cut.

See “Accessories” for order number.
