Intended use
Power Cut
Use the Power Cut cutoff saw outdoors only, for trimming and cut­ting suitable materials, using cutting discs rated for this machine.
Improper use:
Never use the cutoff saw cutting discs for grinding or sanding (using the side of the cutting disc to remove material). The disc can break! Never use the Power Cut with saw blades, cutter blades, brushes, carbide tipped, wood cutting blades etc.
Unauthorised users:
Persons unfamiliar with the operator’s manual, children, young people, and persons under the inuence of alcohol, drugs or med-
ications must not use the Power Cut.
General precautions
- The operator MUST read this operator’s 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 insufciently 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 operator’s 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 qualied 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 inuence of alcohol, drugs, medi-
cation or other substances which may impair vision, dexterity or judgement.
- A re extinguisher must be available in the immediate vicinity
when working in easily inammable vegetation or when it has not rained for a long time (danger of re).
- Asbestos and other materials that can release toxins may be cut
only with the necessary safety precautions and after notication
of the proper authorities and under their supervision or that of a person appointed by them.
- The use of dust-reduction devices is urgently recommended
(see Accessories, pressure water tank, water tank).
- 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.

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: When using personal protective equipment, ensure com­pliance with ANSI Z87.1!
- The kind of clothing should be appropriate, i. e. it should be
tight-tting 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.

- 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 tough material with sufcient
ame-retardant qualities whenever working with the cutoff saw.
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 res (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 oozes into the soil (environmental protection). Use an appropriate base.
- Refuelling is not allowed in closed rooms. Fuel vapors will ac-
cumulate near the oor (explosion hazard).
- Ensure to rmly 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 rst, 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 inammable materials or
explosive gases! The Power Cut can create sparks leading to re 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 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/Stop (I/O) switch,
choke). Visually inspect the mufer for damage and possible dirt in the mufer area.
- 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)
WARNING! Never use carbide tipped, circular saw blades or any kind of wood cutting blades. Never cut any type of wood. Reactive forces can cause severe personal injury from blade contact or thrown tips.
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 disc! This will break the disc (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 arbor hole of the cutting disc must be an exact t with the arbor or shaft. If the arbor hole is larger, it must be tted with an adapter
ring (available as an accessory).
- The cutting disc must be rated for freehand cutting at up to 4370 rpm or 80 m/sec for 350 mm discs, or up to 5100 rpm or 80 m/s for 300 mm discs. Use only cutting discs that comply with EN 12413, EN 13236.
- 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 oper-
ator’s manual (13). Always place your left foot in the rear handle and grasp the other handle rmly (with thumb and ngers). 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 ies 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 ngers.
- 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).
- WARNING – CARBON MONOXIDE PRODUCED DURING USE
CAN KILL – DO NOT USE POWER CUTTER INDOORS – MAKE SURE THERE IS PROPER VENTILATION WHEN USING POWER CUTTER IN TRENCHES OR OTHER CONFINED SPACES.
- 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 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 inam­mable objects. The mufer is very hot (danger of re).
- IMPORTANT: After wet cutting, rst turn off the water feed and then let the disc run at least 30 seconds, to ing off the remaining water
and prevent corrosion.

Kickback, lock-in and gyroscopic forces
- 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 gure 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.
- Gyroscopic forces come into play when handling a power cutter with a rapidly rotating composite wheel.
- The power cut will react in an uncontrolled manner. There is a danger that injuries may occur.
In order to prevent gyroscopic forces developing, please
note the following: Do not rotate the machine rapidly about its longitudinal axis!
15
16
Working behavior / Method of working
- Check the integrity of the composite wheel both before and after
tting it to the machine.
- Before starting work, check the work area for any hazards
(electrical wires, inammable 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 rmly by the front and
rear handles. Never leave the Power Cut unattended!
- Use the Power Cut at high speed as far as possible (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 ung away by the disc with great speed. Injury hazard!
- When cutting workpieces down to length use a rm 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 using synthetic resin cutting discs, always ob­serve the following:
CAUTION:
- Synthetic resin cutting discs can absorb moisture. This moisture can cause the disc to become unbalanced at high speed. This imbalance can cause the disc to break.
- Do not cool resin cutting discs with water or other uids.
- Do not expose resin cutting discs to high humidity or rain!
Do not use resin cutting discs past their use-by date (expira­tion date)! The date (quarter and year) is stamped on the disc’s arbor ring.
EXAMPLE: 04 / 2018
This cutting disc can be used through the end of the fourth quarter of 2018, if properly stored and correctly used.
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 (19) in order to direct the stream of sparks forward, away from the operator (re hazard).
- Determine the cut line, 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!
Cutting masonry and concrete
IMPORTANT! Always wear approved respiratory protection! Asbestos and other materials that can release toxic sub-
stances 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
CAUTION! If there is a chance that the material is under stress, be pre-
pared 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.

21
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 (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.
- 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 at 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.
23
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
mufer (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. CAUTION: Do NOT clean synthetic
resin cutting discs with water or other uids!
Store them lying down at.
• Avoid dampness, freezing temperatures, direct sunshine,
high temperatures and temperature uctuations, as these
can cause breakage and splintering.
• Before re-using a resin cutting disc, make sure of the use-by
(expiration) date (quarter and year, stamped on the arbor ring). If this date has been exceeded, do NOT use the cutting disc.
- Always check new cutting discs or cutting discs that have
been in storage to make sure that they are free of defects and before the rst cut test-run the tool at top speed for at
least 60 seconds. Keep body parts and people well away out of range of the direction of the cutting disc during this test.

Maintenance
- Before performing maintenance work switch off the Power Cut (27) and pull out the plug cap.
- Allow the Power Cut to cool off before doing any mainte­nance work (burn hazard)!
- 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 modications to the Power Cut! You will only be putting your own safety at risk!
Perform only the maintenance and repair works described in
the operator’s 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.

Sequence
Mounting the cutting disc
Check the integrity of the composite wheel both before and after tting it to the machine.
See SAFETY INSTRUCTIONS, Page 6.
Unscrew screw (9) and remove the spring washer (8). Place the cutting disc (5) on the arbour (7).
NOTE:
The arbor hole of the cutting disc must be an exact t with the
arbor or shaft. Ensure that the composite wheel is seated correctly!
For cutoff discs with 25.4 mm (1”) arbor holes, use the cor­rect size disc holder (supplied only with cutoff discs with 25.4 mm (1”) arbor holes). Non-compliance can cause serious
injury!
Make sure the cutting disc is installed so it turns in the right direction, if a direction is marked on the disc.

Fuels
Caution:
This tool uses petroleum products (gasoline and oil).
Be especially careful when handling gasoline. Do not smoke. Do not allow gasoline to come near ames,
sparks or re (explosion hazard).
Fuel mixture
This tool is powered by a high-performance air-cooled 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 89 (R+M)/2. 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.
To lubricate the engine, use a synthetic oil for two-stroke air-coo­led engines (quality grade JASO FC or ISO-L-EGD), which has to be added to the fuel.
The correct mixture ratio: 50:1 When using MAKITA synthetic two-stroke engine oil, i.
e. 50 parts gasoline to 1 part oil.
50:1 When using other synthetic two-stroke engine
oil (quality grade JASO FC or ISO -L -EGD), i. e. 50 parts gasoline to 1 part oil.

The Storage of Fuel
Fuels have a limited storage life. Fuel and fuel mixtures age through evaporation, especially at high tempera­tures. Aged fuel and fuel mixtures can cause starting problems and damage the engine.
Purchase only that amount of fuel, which will be consu­med over the next few months. At high temperatures, once fuel has been mixed it should be used up in 6-8 weeks.
Store fuel only in proper containers, in dry, cool, secure locations!
MAKITA synthetic two-stroke engine oil (50:1) is available in the following sizes to suit your individual requirements:
2.6 oz. order number T-00745
6.4 oz. order number T-00739
NOTE: For preparing the fuel-oil mixture rst mix the entire oil
quantity with half of the fuel required, then add the remaining fuel.
Thoroughly shake the mixture before lling it into the tank.
Caution: Open the tank cap carefully, as pressure might have built up inside!
It is not wise to add more engine oil than specied to ensure safe operation. This will only result in a higher production of combustion residues which will pollute the environment and clog the exhaust channel in the cylinder as well as the mufer. In addition, fuel consumption will rise and performance will decrease.
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!

Fuel mixture
Refuelling IMPORTANT:
FOLLOW THE SAFETY PRECAUTIONS!
Be careful and cautious when handling fuels. The engine must be turned off and cooled down!
Carefully clean the area around the fuel-tank ller neck to keep
dirt from getting in the tank.
Place the Power Cut on an even surface.
Unscrew the tank cap and ll tank with fuel mixture. Take care
to avoid spilling.
Screw the tank cap back on hand-tight.
Clean screw cap and tank after refuelling. Never start or operate the Power Cut in the same place as it was fuelled!
If fuel gets on your clothing, change clothes immediately.

Warmstart:
As described above for cold starting, but before starting push the combination switch (3) up (Choke position) and
then right away back to the middle “ON” position. This is only
to engage the half-throttle lock. If the engine doesn’t start after
2 or 3 pulls, repeat the entire starting procedure as described for cold starting.
NOTE: If the engine was switched off only for a short time, the saw can be started without using the combination switch.
Important: If the fuel tank has been completely emptied and the engine has stopped due to lack of fuel prime the fuel pump (4) by pressing it several times until you can see fuel in the pump.
Stopping the engine
Depress the combination switch (3). NOTE: After being pressed down, the combination switch will
revert to the ”ON” position again. The engine is switched off, but can be turned on again without moving the combination switch.
IMPORTANT: To cut off the ignition current, push the combi­nation switch all the way down past the resistance point to the safety position (
).

Adjusting the carburetor
NOTE: The grinding parts are equipped with an electronic ignition to limit the speed.
At the factory the idling speed has been set to approx. 2600 rpm, but the running-in process of a new engine may require slight readjustment of the idling speed.
Adjustments to the adjusting screws (L) and (H) may only be made by an authorised MAKITA service center.
SERVICE

For correct adjustment of the idling speed the following steps must be carried out:
T
L
Start the engine and run it until it is warm (about 3 - 5 minutes).
Adjust the carburetor with the screwdriver (7) included with the Power Cut. It has a lug that helps with adjustment.
Readjust the idling speed.
If the cutoff disc turns when the engine is idling, turn the throttle stop screw (T) counter-clockwise in small increments until the disc no longer turns.
If the engine suddenly stops in idle, turn the screw back slightly clockwise.
Switch off the engine.
MAINTENANCE
CAUTION:
Before doing any work on the Power Cut turn off the engine, remove the cutting disc, pull the plug cap off the spark plug and wear protective gloves!
