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.
-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 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 pilled 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
-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 bothhands. 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 willkeep 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.
15
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.
19
20
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.
8
21
In wet cutting, the disc is wetted at an equal rate on both sides by
a trickle of water. DOLMAR 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 (22), 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 (23, 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 (24).
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.
22
Transport and storage
-Always turn off the Power Cut when transporting it or
moving it from place to place on a site (25).
-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 (25). 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
STOP
-Before performing maintenance work switch off the Power
Cut (26) 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
DOLMAR Service.
Use only original DOLMAR spares and accessories.
The use of non-DOLMAR 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
DOLMAR.

V-belt tension will result in premature wear to the V-belt
and V-belt wheel or damage to the clutch bearing.
NOTE: The two fastening nuts (11) must be loosened before
tightening the V-belt or checking the tension.
To increase the belt tension, turn the tightening screw (12) to
the right (clockwise) with the combination wrench included with
the Power Cut.
The belt tension is correctly adjusted when the nut (13) is
centred on the mark (14).

IMPORTANT:
After tightening/inspection, make certain to tighten
the fastening nuts (11) (30 ± 2 Nm).

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 DOLMAR
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 DOLMAR 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.
The correct mixture ratio:
100:1 When using DOLMAR HP 100 high-perfor-
mance two-stroke engine oil, i. e. 100 parts
gasoline to 1 part oil.
50:1When using DOLMAR high-performance two-
stroke engine oil, i. e. 50 parts gasoline to 1
part oil.

requirements:
1 l Best.-Nr. 980 008 107
100 ml Best.-Nr. 980 008 106
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 combustion residues which will pollute
the environment and clog the exhaust channel in the
A
cylinder as well as the muffler. In addition, fuel consumption 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 dry out. 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!

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 filler neck to
keep dirt from getting in the tank.
Place the unit on its side on an even surface.
Unscrew the tank cap and fill tank with fuel mixture. Take care
to avoid spilling.
Tightly screw on the cap.
Clean screw cap and tank after refuelling. Never start or
operate the Power Cut in the same place as it was fuelled!

SPECIAL ACCESSORIES
Diamond cutting discs (1)
DOLMAR 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 DOLMAR 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).
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.
To keep down dust and for better cutting-disc cooling, DOLMAR
offers several options for wetting the disc during operation.
