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 Instruction Manual, children, young

people, and persons under the in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 us-

ing cutoff saws). It is important to be familiar with the opera-

tion 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 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 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, medica

-

tion 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).

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-

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.

- 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.

6

- 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 im

-

mediately. 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 pre-

scriptions. 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 inspec

-

tion. Never use the Power Cut when it is not completely as-

sembled.

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 dur-

ing 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 3850

rpm or 80 m/sec for 400 mm discs, 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 foot

-

ing.

- Put the Power Cut into operation only as described in this instruc

-

tion 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, 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 inam

-

mable 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 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 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, 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 “Tech-

nical 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 de-

signed!

- Use cutting discs only for the materials for which they are de-

signed. 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 rota-

tion.

- 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.

When using synthetic resin cutting discs, always ob-

serve 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 (expira-

tion date)! The date (quarter and year) is stamped on the disc’s

arbor ring.

EXAMPLE: 04 / 2013

This cutting disc can be used through the end of the fourth quarter

of 2013, 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 supervi-

sion 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 pos-

sible (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 circumfer-

ential 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 mate

-

rial 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 ac

-

cident 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 respon-

sible 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.

10

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 pos-

sible (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 trolley (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 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 cut

-

ting 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. Before transporting in a vehicle, allow the Power Cut

to cool off completely. Note: Mufers with catalytic converters

take longer to cool off!

- 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 mainte-

nance work (burn hazard)!

- Power Cuts with catalytic converter take longer to cool

down!

- 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.

- Do not operate the Power Cut with a defective or modied

mufer.

- 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 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.

First aid

For the event of a possible accident, please make sure that a

rst aid kit is always immediately available close by. Immediately

replace any items used from the rst aid box.

When calling for help, give the following information:

- Place of the accident

- What happened

- Number of injured people

- Kind of injuries

- Your name!

NOTE

Individuals with poor circulation who are exposed to excessive

vibration may experience injury to blood vessels or the nervous

system.

Vibration may cause the following symptoms to occur in the n-

gers, hands or wrists: ”Falling asleep” (numbness), tingling, pain,

stabbing sensation, alteration of skin colour or of the skin. If any

of these symptoms occur, see a physician!

Disposal and environmental protection

Be mindful of the environment!

Dispose of worn-out or defective cutting discs in accordance with

your local disposal regulations. To protect unusable cutting discs

from misuse, destroy them before disposal.

When the Power Cut is worn out or damaged beyond repair, have

it disposed of or recycled in an environmentally sound manner. If

necessary, consult your local authorities.

Insert the Allen key (2) as far as it will go. The shaft is now

blocked.

Tighten the screw with the combination wrench (1)

NOTE: Tighten the screw rmly (30 ± 2 Nm), as otherwise

the cutting wheel may slip during cutting.

Mounting the cutting disc

Inspect the disc for damage.

See SAFETY INSTRUCTIONS, Page 7.

Unscrew screw (9) and remove the spring washer (8).

Place the cutting disc (5) on the arbour (7).

Hinweis: 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 (*).

Make sure the cutting disc is installed so it turns in the right

direction, if a direction is marked on the disc.

PUTTING INTO OPERATION

CAUTION:

Always turn off the engine and pull off the spark plug cap

before doing any work on the Power Cut! Always wear

protective gloves!

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 87 (R+M)/2. In case no such fuel is avail-

able, 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.

Gasoline

50:1

+

The correct mixture ratio:

50:1 When using DOLMAR High Performance two-

stroke engine oil, i. e. 50 parts gasoline to 1

part oil.

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 unit on its side 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 op-

erate the Power Cut in the same place as it was fuelled!

If fuel gets on your clothing, change clothes immediately.

Fuel mixture

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!

DOLMAR High Performance two-stroke engine oil (50:1) is

available in the following sizes to suit your individual require-

ments:

2.6 oz. order number 986 100 100

6.4 oz. order number 986 100 101

NOTE: For preparing the fuel-oil mixture rst mix the entire oil

quantity with half of the fuel required, then add the remaining

fuel. Shake the nished mixture thoroughly before pouring 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.

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.

Use only approved and marked containers for transport

and storage. Store fuel only in dry, cool and secure

locations!

18

Starting the engine

This model is tted with a semiautomatic decompression valve

(1) to make starting easier. Press the rubber cover until you

can feel it engage. This pushes in the deompression valve

behind it. This in turn reduces the compression, so that it takes

less force to pull the starter cord to accelerate the engine to its

starting speed.

The high pressure in the combustion chamber after the rst

ignition automatically closes the decompression valve.

if

necessary

CAUTION:

Observe the SAFETY INSTRUCTIONS on page 4 and 5!

Start the Power Cut only after complete assembly and

inspection!

Move at least 3m (10 feet) away from the place where you

fuelled the Power Cut.

Make sure you have a good footing, and place the Power

Cut on the ground in such a way that the cutting disc is

not touching anything.

3 meters

Move the protective hood (3) into the proper position for the

work you intend to do (see illustration).

Grasp the grip (2). The hood (3) can swing in both ways within

its range of motion.

Caution:

Always make sure that the straight outer edge of the impact plate

(4) and the edge of the hood are parallel (see arrows).

If this is not the case, take the tool to a service center.

19

Stopping the engine

Push the combination switch (6) down to position .

Warm starting:

As described above for cold starting, but before starting push

the combination switch (6) up (Choke position) and then right

away back to the middle “I” 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.

Do not leave switch in the choke position when hot

starting!

Cold starting:

Grasp front handle rmly with one hand and press the Power

Cut against the ground.

Place left toe in the rear handguard.

Push the combination switch (6) up (choke position). This will

automatically activate the half-throttle lock.

NOTE: If the Power Cut is mounted on the trolley, do not

operate the gas lever (throttle) on the side of the trolley!

Pull the starter cable out slowly until you feel resistance (piston

is now just before top dead center).

Press in the decompression valve (5).

Pull starter cable quickly and rmly, until you hear the rst

ignition, but to a max. of 3-5 pulls!

Important: Do not pull the starter cable out more than about

50 cm / 20”, and guide it back slowly by hand (instead of letting

it snap back).

Press in the decompression valve (5).

Move the combination switch (6) to the middle “I” position.

Again pull the starter cable quickly and rmly.

As soon as the engine is running, grasp the rear handle (the

safety lock switch (8) will be depressed by the palm of your hand)

and tap the throttle (9). The half-throttle lock will be disengaged

and the engine will run in idle.

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.

2500 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 DOLMAR service center. Accor-

dingly, the holes for the two screws are sealed shut.

For correct adjustment of the idling speed the following

steps must be carried out:

Start the engine and run it until it is warm (about 3 - 5

minutes).

Adjust the carburetor with the screwdriver (1, Order No. 944

340 001) included with the Power Cut. It has a lug that helps

with adjustment.

Readjust the idling speed.

If the cut-off disc is still turning when the engine is running,

unscrew the adjusting screw of the throttle valve (2) until the

cut-off disc is no longer turning. When the engine is left running

at idling speed, tighten the screw a little.

Switch off the engine
