with the product!
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 etc.
Unauthorised users:
Persons unfamiliar with the Instruction Manual, children, young
people, and persons under the inß uence of alcohol, drugs or medi-
cations must not use the Power Cut.
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 opera-
tion of this particular cutoff saw. Users insufÞ 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 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 qualiÞ 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 inß uence of alcohol, drugs, medica-
tion or other substances which may impair vision, dexterity or
judgement.
- A Þ re extinguisher must be available in the immediate vicinity
when working in easily inß ammable vegetation or when it has
not rained for a long time (danger of Þ re).
- Asbestos and other materials that can release toxins may be cut
only with the necessary safety precautions and after notiÞ 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).
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-
Þ 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.
4
- 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 tough material with sufÞ cient
ß 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 Þ 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 accumulate near the ß oor (explosion hazard).
- Ensure to Þ rmly tighten the screw cap of the fuel tank.
- Before starting the engine, move to a location at least 3 meters
(approx. 3 1/4 yards) 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 Þ 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 inß ammable materials or
explosive gases! The Power Cut can create sparks leading
to Þ re or explosion!
- Make sure that all persons within 30 meters (33 yards), 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 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).
- 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 disc! This will break
the disc (10)!
Caution!
Never change direction (turning radius less than 5 meters /
5 1/2 yards), 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 Þ t with the
arbor or shaft. If the arbor hole is larger, it must be Þ 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 instruction manual (13). Always place your left foot in the rear handle
and grasp the other handle Þ rmly (with thumb and Þ 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 ß 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 Þ 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).
- Switch off the Power Cut immediately if you observe any
changes in its operating behavior.
- Switch off engine before refuelling, changing the cutoff disc, work
breaks, transporting or moving the Power Cut, taking it out of
operation, or dealing with malfunctions. Before any maintenance
work, move the combination switch to the lock symbol (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
inß ammable objects. The mufß er is very hot (danger of Þ re).
- IMPORTANT: After wet cutting, Þ rst turn off the water feed and
then let the disc run at least 30 seconds, to ß ing 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 Þ 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.
Working behavior / Method of working
- Before starting work, check the work area for any hazards
(electrical wires, inß 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 Þ 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 ß ung away by the disc with great speed. Injury
hazard!
- When cutting workpieces down to length use a Þ 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 ß 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 / 2015
This cutting disc can be used through the end of the fourth quarter
of 2015, 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 (Þ 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!
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.

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
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 ß 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.
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
mufß 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 ß uids!
• Store them lying down ß at.
• Avoid dampness, freezing temperatures, direct sunshine,
high temperatures and temperature ß 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 Þ 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.
