The use of protective clothing does not eliminate injury risks, but reduces the injury effects in case of accident. Consult your trusted supplier to choose equipment in compliance with legislation. The clothing must be proper and not an obstacle. Wear adherent protective clothing. Protective jackets and dungarees leggings are ideal. Do not wear clothes, scarves, ties or bracelets that may get stuck into twigs. Tie up and protect

long hair (example with foulards, cap, helmets, etc.). Safety boots having skid-

proof sole and anti-piercing insert. Wear protective goggles or face screens. Use protections against noises: for example, noise reduction ear guards or earplugs.

The use of protections for the ear requires much more attention and caution, because the perception of audible warning signals (screaming, alarms, etc.) is limited. Always remove your hearing protection as soon as the engine stops. Wear gloves that permit the maximum absorption of vibrations.

• Only allow others to use this brush cutter who have read this Operator’s Manual or received adeguate instructions for the safe and proper use of this brush cutter.

• Check the brush cutter each day to ensure that each device, whether for safety or otherwise, is functional.

• Never use a damaged, modiﬁ ed, or improperly repaired or assembled brush cutter. Do not remove, damage or deactivate any of the safety devices. Only use cutting tools indicated in the table (page 10). Always replace cutting tools or safety devices immediately if it becomes damaged, broken or is otherwise removed.

• Carefully plan your operation in advance. Do not start cutting until you have a clear work area, secure footing, and a planned retreat path.

• All brush cutter service, other than the operations shown in the present manual, have to be performed by competent personnel.

• The brush cutter must only be used for trimming grass, grass clearing and / or forestry clearing. It is unadvisable to cut other types of material.

• It is unadvisable to hitch tools or applications to the P.t.o. that are not speciﬁ ed by the manufacturer.

SAFETY RULES

Fuel Handling

WARNING: Gasoline is an extremely ﬂ ammable fuel. Use extreme caution when handling gasoline or fuel mix. Do not smoke or bring any ﬁ re or ﬂ ame near the fuel or the brush cutter.

WARNING: Fuel and fuel fumes can cause serious injury when inhaled or allowed to come in contact with the skin. For this reason observe caution when handling fuel and make sure there is adequate ventilation.

WARNING: Beware of carbon monoxide poisoning.

WARNING! – Mufﬂ ers ﬁ tted with catalytic converters get very hot during use and remain so for some time after stopping. This also applies at idle speed. Contact can result in burns to the skin. Remember the risk of ﬁ re!

• Tighten fuel cap securely after refuelling.

Unit vibration can cause an improperly tightened fuel cap to loosen or come off and spill quantities of fuel.

• Wipe spilled fuel from the unit and allow

remaining fuel to evaporate. Move 10 feet (3 m) away from refuelling site before starting engine.

• Never attempt to burn off spilled fuel under

any circumstances.

• Do not smoke while handling fuel or while

operating the brush cutter.

• Store fuel in a cool, dry, well ventilated

place.

• Never place the brush cutter in a

combustible area such as dry leaves, straw, paper, etc.

• Store the unit and fuel in an area where

fuel vapors cannot reach sparks or open ﬂ ames from water heaters, electric motors or switches, furnaces, etc.

• Never take the cap off the tank when the

engine is running.

• Never use fuel for cleaning operations.

• Take care not to get fuel on your clothing.

If you have spilt fuel on yourself or your clothes, change your clothes. Wash any part of your body that has come in contact with fuel. Use soap and water.

• Don’t expose fuel tank to direct sunlight.

• Keep fuel out of reach of children.

Operation and Safety

• To reduce the risk of ﬁ re and burn injury, handle fuel with care. It is highly ﬂ ammable.

• Mix, store and transport fuel in a container approved for gasoline.

• Mix fuel outdoors where there are no sparks or ﬂ ames.

• Select bare ground, stop engine, and allow to cool before

refuelling.

• Loosen fuel cap slowly to release pressure and to keep fuel from escaping around the cap.

WARNING: Always hold the brush cutter with both hands when the engine is running. Use a ﬁ rm grip with thumbs and ﬁ ngers encircling the brush cutter handles (Fig. 2).

SAFETY RULES

brush cutter, use the appropriate blade guard (Fig. 3). When transporting in a vehicle, keep blade covered with the guard. Properly secure your brush cutter to prevent turnover, fuel

spillage and damage.

• Do not operate a brush cutter with one hand! Serious injury to the operator, helpers, bystanders, or any combination of these persons may result from one-handed operation. A brush cutter is intended for two-handed use.

• Before you start the engine, make sure the cutting attachment is not contacting any object.

• Shut off the engine before setting down the brush cutter. Do not leave the engine running unattended.

• Only use the brush cutter in well-ventilated places, do not operate the brush cutter in explosive or ﬂ ammable atmospheres or in closed environments. Beware of carbon monoxide poisoning.

• Do not operate brush cutter from a ladder or in a tree. Always cut from a ﬁ rm-footed and safe position.

WARNING: Take great care when working on sloping ground.

• Do not cut near electric cables.

• Keep the handles dry, clean, and free of oil or fuel mixture.

• Never cut with the brush cutter above shoulder height.

• Never use the brush cutter without blade guard or the head guard.

• Do not start the engine with the arm not mounted.

Precautions Against Kickout

WARNING: Avoid kickout which can result in serious injury. Kickout is the sideward, or

sudden forward motion of the machine occurring when the blade contacts any object such as a log or stone, or when the wood closes in and pinches the saw blade in the cut. Contacting a foreign object can also result in loss of brush cutter control.

Reduce the Risk of Kickout

WARNING: Recognize that kickout can happen. With a basic understanding of kickout, you can reduce the element of surprise which contributes to accidents.

• Never let the moving blade contact any object.

• Keep the working area free from obstructions such as other trees, branches, rocks, fences, stumps, etc. Eliminate or avoid any obstruction that your blade could hit while you are cutting.

• Keep your blade sharp. Follow manufacturer’s blade sharpening and maintenance instructions.

• Begin and continue cutting at full speed. If the blade is moving at a slower speed, there is greater chance of kickout

occurring.

Maintain Control

• Keep a good, ﬁ rm grip on the brush cutter with both hands when the engine is running and don’t let go (Fig. 2). A ﬁ rm grip will help you reduce kickout and maintain control of the brush cutter.

Keep the ﬁ ngers encircling the handle.

• Stand with your weight evenly balanced on both feet.

• Do not overreach. You could be drawn or thrown off balance and lose control of the brush cutter.

SAFETY RULES

Safety equipment checking

WARNING: Never use a machine with faulty safety equipment. The machine’s safety equipment must be checked and maintained as described in this section. If your machine fails any of these checks contact your service agent to get it repaired.

Throttle lock

The throttle lock is designed to prevent accidental operation of the throttle control. This arrangement means that the throttle control is automatically locked at the idle setting. Make sure the throttle control is locked at the idle setting when the throttle lock is released. Press the throttle lock and make sure it returns to its original position when you release it. Check that the throttle control and throttle lock move freely and that the return springs work properly.

Stop switch

Use the stop switch to switch off the engine. Start the engine and make sure the engine stops when you move the stop switch to the stop setting.

Cutting attachment guard

This guard is intended to prevent loose objects from being thrown towards the operator. The guard also protects the operator from accidental contact with the cutting attachment. Check that the guard is undamaged and not cracked. Replace the guard if it has been exposed to impact or is cracked. Always use the recommended guard for the cutting attachment you are using. See chapter on Technical data.

WARNING: Never use a cutting attachment without an approved guard. See the section on Technical Data. Use of an incorrect or faulty guard may lead to serious personal injury.

Precautions to Reduce Vibration Risk

• The brush cutter is provided with antivibration (AV) system; never alter or modify it.

• Wear gloves and keep your hands warm.

• Keep the blade sharp and the brush cutter, including the AV system, well maintained. A dull blade will increase the vibrations transmitted to your hands.

• When using a string cord attachment check that the cord is correctly wound; an unbalanced attachment will highly increase the vibration level.

• Maintain a ﬁ rm grip at all times, but do not squeeze the handles with constant, excessive pressures, take frequent breaks. All the above mentioned precautions do not guarantee that you will not sustain whiteﬁ nger disease or carpal tunnel syndrome. Therefore, continual and regular users should monitor closely the condition of their hands and ﬁ ngers. If any of the above symptoms appear, seek medical advice immediately.

Maintenance Precaution

WARNING: Never operate a brush cutter that is damaged, improperly adjusted, or is not completely and securely assembled.

• Be sure that the cutting attachment stops moving when the throttle control trigger is released. If the cutting attachment moves

at idle speed, the carburetor may need adjusting, see Operation-Carburetor Adjusting Section. If the cutting attachment still moves at idle speed after adjustment

has been made, contact a Servicing Dealer for adjustment and discontinue use until the repair is made.

WARNING: All brush cutter service, other than items in the Operator’s Manual maintenance instructions, must be performed by competent brush cutter service personnel. (If improper tools are used to remove the ﬂ ywheel or clutch, or if an improper tool is used to hold the ﬂ ywheel in order to remove the clutch, structural damage to the ﬂ ywheel could occur which could cause the ﬂ ywheel to burst and serious injury could result.)

• Never modify your brush cutter in any way.

• Keep the handles dry, clean, and free of oil or fuel mixture.

SAFETY RULES

WARNING: Use only recommended accessories and replacement parts.

• Never touch the cutting attachment or attempt to service the brush cutter while the engine is running.

• Never use fuel for cleaning operations.

• Keep the brush cutter in a dry place, off the ground with the blade guard on and the tanks empty.

• If your brush cutter is no longer usable, dispose of it properly without damaging the environment by

handing it in to your local Dealer who will

arrange for its correct disposal.

• Replace immediately any safety device when damaged or broken.

OPERATION

Fueling

Do Not Smoke!

This product is powered by a 2-cycle engine and requires pre-mixing gasoline and 2-cycle oil. Pre-mix unleaded gasoline and 2-cycle engine oil in a clean container approved for gasoline. RECOMMENDED FUEL: THIS ENGINE IS CERTIFIED TO OPERATE ON UNLEADED GASOLINE INTENDED FOR AUTOMOTIVE USE WITH AN OCTANE RATING OF 89 ([R + M] / 2) OR HIGHER. Mix 2-Cycle Engine Oil with gasoline according to the instructions on the package. We strongly recommend the use of 2% (50:1) Efco Two Cycle Engine Oil, which is speciﬁ cally formulated for all Efco air-cooled two-stroke engines. The correct oil / fuel proportions shown in the table below are suitable when using the Efco Two Cycle Engine Oil or an equivalent highquality engine oil (JASO speciﬁ cation FD or ISO speciﬁ cation L-EGD). When oil speciﬁ cations are NOT equivalent or unknown use 4% (25:1) fuel / oil mixing ratio.

CAUTION - For the mixture, never use a fuel with an ethanol percentage higher than 10%; gasohol (mixture of gasoline and ethanol) up to 10% ethanol or E10 fuel are acceptable.

When using an oxygenated gasoline a good practice of fuel management is necessary. Gasoline oxygenated with alcohol readily takes up water when it is present; the water may be condensed out of humid air or be a contaminant in the fuel system, including tank. The use of oxygenated gasoline may cause the occurrence of vapor-lock easier.

NOTE - Prepare only the quantity of mixture required for immediate use; do not leave fuel in the tank or a container for a long time. Were commend the use of the additive Emak ADDITIX 2000 code 001000972 if the mixture is to be stored for 30 days.

Alkylate gasoline

CAUTION: DO NOT USE AUTOMOTIVE OIL OR 2-CYCLE OUTBOARD OIL.

CAUTION:

- Match your fuel purchases to your consumption; don’t buy more than you will use in one or two months;

- Store gasoline in a tightlyclosed validate container in a cool, dry place.

CAUTIONS – Alkylate fuels have different density than normal fuel. Therefore engines, set with normal fuel, need different H jet regulation to avoid critical issues. For this operation it’s necessary turned at a Licensed Service Dealer.

Filling the Tank

WARNING: Follow safety instruction for fuel handling. Always shut off engine before fuelling. Never add fuel to a machine with a running or hot engine. Move at least 10 feet (3 m) from refuelling site before starting engine. DO NOT SMOKE!

1. Clean surface around fuel cap to prevent contamination.

2. Loosen fuel cap slowly.

3. Carefully pour fuel mixture into the tank. Avoid spillage.

4. Prior to replacing the fuel cap, clean and inspect the gasket.

5. Immediately replace fuel cap and hand tighten. Wipe up any fuel spillage.

WARNING: Check for fuel leaks, if any are found, correct before use. Contact a Servicing Dealer if necessary.

WARNING: To use the blades with the brush cutters DS 2200 S and DS 2400 S must be purchased the kit p.n. 61370224.

WARNING: When using rigid blades (only S and T models), avoid cutting close to fences, sides of buildings, tree trunks, stones or other such objects that could cause the brush cutter to kick out or could cause damage to the blade. We recommends use of the nylon line heads for such jobs. In addition, be alert to an increased possibility of ricochets in such situations.

WARNING: The brush cutter is normally to be used at ground level with the cutting attachment parallel to the ground. Use of a brush cutter above ground level or with the cutting attachment perpendicular to the ground may increase the risk of injury, since the cutting attachment is more fully exposed and the brush cutter may be more difﬁ cult to control. Never use your brush cutter as a hedge trimmer.

WARNING: If the blade loosens after being properly tightened, stop work immediately. The retaining nut may be worn or damaged and should be replaced. Never use unauthorized parts to secure the blade. If the blade continues to loosen, see your dealer. Never use a brush cutter with a loose blade.

Basic Cutting Procedure

1. Wear non-slip gloves for maximum grip and protection.

WARNING: Hold the brush cutter ﬁ rmly with both hands (Fig. 2). Always keep your body to the

left of tube. Never use a crosshanded grip. Left-handers should follow these instructions too. Keep a proper cutting stance.

2. Maintain a proper grip (Fig. 2) on the brush cutter whenever the engine is running. The ﬁ ngers should encircle the handlebar and the thumb is wrapped under the handlebar.

Fitting the harness

DS 2200 T – DS 2400 T models

Into S models, the harness is optional (not included but available separately). On these models the harness attachment point is not adjustable (19B, Fig.1). Correct adjustment of the harness permits the brush cutter to be properly balanced and at an appropriate height from the ground (Fig. 10).

- Put on the single harness.

- Hook the brush cutter to the harness using the hook (A, Fig. 10).

- Position the hook (19B, Fig. 1) to obtain the best brush cutter balance (only T model).

- Position the buckle (C, Fig. 11) to obtain the correct brush cutter height.

Correct balance

1 Forestry clearing

The machine is balanced by moving the support ring on the machine forwards or backwards. The machine is correctly balanced when it freely hangs horizontally from the support hook. In this way the risk of hitting stones is reduced if you need to release the handlebar.

2 Grass clearing

Let the blade balance at a comfortable cutting

OPERATION

height, i.e. close to the ground.

Work Area Precautions

WARNING: Cut only grass or weed. Do not cut metal, plastics, masonry, or non-wood building materials.

• Never allow children to operate your brush cutter. Only allow others to use this brush cutter who have read this Operator’s Manual or received adequate instructions for the safe and proper use of this brush cutter.

• Keep everyone - helpers, bystanders, children, and animals at a safe distance from the cutting area. During operations, keep a minimum distance of 50 feet (15 m) between workers.

• Always cut with both feet on solid ground to prevent being pulled off balance.

• Make sure you can move and stand safely. Check the area around you for possible obstacles (roots, rocks, branches, ditches, etc.) in case you have to move suddenly. Take great care when working on sloping ground.

• Do not cut above chest height, as a brush cutter held higher is difﬁ cult to control against kickout forces.

• Do not work near electrical wires. Leave this operation for professionals.

• Cut only when visibility and light are adequate for you to see clearly.

• Do not cut from a ladder, this is extremely

dangerous.

• Stop the brush cutter if the blade strikes a foreign object. Inspect the brush cutter and repair parts as necessary.

• Keep the blade out of dirt and sand. Even a small amount of dirt will quickly dull a blade and increase the possibility of kickout.

• Stop the engine before setting the brush cutter down.

OPERATION

• Be particularly cautious and alert while wearing hearing protection because such equipment may restrict your ability to hear sounds indicating danger (calls, signals, warnings, etc).

• Be extremely cautious when working on slopes or uneven ground.

WARNING: Never use rigid blades when cutting in stony areas. Thrown objects or damaged blades may result in serious or fatal injury to the operator or bystanders. Watch out for thrown objects. Always wear approved eye protection. Never lean over the cutting attachment guard. Stones, rubbish, etc. can be thrown up into the eyes causing blindness or serious injury. Keep unauthorised persons at a distance. Children, animals, onlookers and helpers should be kept outside the safety zone of 50 ft (15 m). Stop the machine immediately if anyone approaches. Never swing the machine around without ﬁ rst checking behind you to make sure no-one is within the safety zone.

WARNING: Never cut when visibility is poor or in very high or low temperatures or in freezing weather.

Starting The Engine

WARNING: When the engine is started with the choke in either the choke or start throttle positions the cutting attachment will start to rotate immediately.

• Place the brush cutter on level ground and ensure that no objects or obstructions are in immediate vicinity which could come in contact with the cutting attachment. Hold the body of the machine on the ground using your left hand (CAUTION! Not with

your foot!), see Fig. 12.

Start-up procedure

1) Slowly push the purge bulb 6 times (9, Fig.1).

2) Pull the choke lever (15, Fig.1) in the CLOSE position (A, Fig.13). In so doing, it also activates automatically halfthrottle.

3) Place the brush cutter on the ground in a stable position. Check that the blade is free. Holding the brush cutter down (Fig.12), pull the starter rope until the ﬁ rst kick over of the engine is heard (no more than 3 pulls). A new unit may require additional pulls.

4) Push the choke lever (15, Fig.1) in OPEN (I) position (B, Fig.13).

5) Pull the starter cord to start the engine. Once the machine is started, warm up the machine for about few seconds, without touch the throttle lever. The machine could need more seconds to warm up with cold weather or at high altitudes. Finally, put the choke lever (18, Fig.1) for deactivate the automatic half-throttle.

CAUTION:

- Never wrap the starter cord around your hand.

- When pulling the starter rope, do not use the full extent of the rope as this can cause the rope to break.

- Do not let starter rope snap back. Hold the starter handle (14, Fig.1) and let the rope rewind slowly.

WARNING: Do not cut material with the choke lever at the CLOSE

position. Do not operate your brush cutter with the starting throttle lock engaged. Cutting with the starting throttle lock engaged does not permit the operator proper control of the brush cutter.

NOTE - STARTING WARM ENGINE: Follow above starting instructions, but do not use the CLOSE position for start up again.

WARNING: Weather conditions and altitude may affect carburetion. Do not allow bystanders close to the brush cutter while adjusting the carburetor.

Keep the engine at full throttle the entire time you are cutting.

NOTE: It is normal for smoke to be emitted from a new engine during and after ﬁ rst use.

Breaking-in the Engine

OPERATION

Difﬁ cult Starting (or starting a ﬂ ooded engine)

The engine may be ﬂ ooded with too much fuel if it has not started after 10 pulls. Flooded engines can be cleared of excess fuel by following the warm engine starting procedure listed above. Ensure the ON/STOP switch is in the ON position. Starting could require pulling the starter rope handle many times depending on how badly the unit is ﬂ ooded. If engine fails to start refer to the TROUBLESHOOTING TABLE (page 31).

Engine is Flooded

• Set the on/off switch to STOP.

• Engage a suitable tool in the spark plug boot.

• Pry off the spark plug boot.

• Unscrew and dry off the spark plug.

• Open the throttle wide.

• Pull the starter rope several times to clear the combustion chamber.

• Reﬁ t the spark plug and connect the spark plug boot, press it down ﬁ rmly – reassemble the other parts.

• Set the on/off switch to I, the starting position.

• Set the choke lever to OPEN position – even if engine is cold.

• Now start the engine.

The engine reaches the maximum power after 5-8 hours of activity. During this period of breaking-in do not make the machine function idly at full throttle, to avoid excessive functioning stress.

CAUTION! – During the breakingin period do not vary the carburetion to obtain a presumed power increment; the engine can be damaged.

Stopping The Engine

Release the throttle trigger (18, Fig. 1) and let the engine return to idle. To stop the engine, push the switch (17). Do not put the brush cutter on the ground when the cutting attachment is still moving. In the event that of the switch will not function, pull the choke lever in the CLOSE position (A, Fig. 13) to stop the engine.

OPERATION

Pre-operation checking

WARNING: THE CUTTING ATTACHMENT SHOULD NEVER TURN AT IDLE. Turn the idle speed screw “T” counter-clockwise to reduce the idle RPM, or contact a Servicing Dealer for adjustment and discontinue use until the repair is made. Serious personal injury may result from the cutting attachment turning at idle.

A damaged clutch may cause a cutting attachment to rotate at idle speed and increase the risk of personal injury from loss of control and from contact with the cutting tool.

Working Techniques

General working instructions

WARNING: This section describes the basic safety precautions for working with brush cutter and trimmers. If you encounter a situation where you are uncertain how to proceed you should ask an expert. Contact your dealer or your service workshop. Avoid all usage which you consider to be beyond your capability. You must understand the difference between forestry clearing, grass clearing and grass trimming before use.

Basic safety rules

1. Look around you:

• To ensure that people, animals or other things cannot affect your control of the

machine.

• To ensure that people, animals, etc., do not come into contact with the cutting attachment or loose objects that are thrown out by the cutting attachment.

WARNING: Do not use the machine unless you are able to call for help in the event of an accident.

2. Do not use the machine in bad weather,

such as dense fog, heavy rain, strong wind, intense cold, etc. Working in bad weather is tiring and often brings added risks, such as icy ground, unpredictable felling direction, etc.

3. Make sure you can move and stand safely.

Check the area around you for possible obstacles (roots, rocks, branches, ditches, etc.) in case you have to move suddenly. Take great care when working on sloping ground.

4. Switch off the engine before moving to

another area.

5. Never put the machine down with the

engine running.

• Always use the correct equipment.

• Make sure the equipment is well adjusted.

• Follow the safety precautions.

• Organise your work carefully.

• Always use full throttle when starting to cut with the blade.

• Always use sharp blades.

• Avoid stones.

WARNING: Neither the operator of the machine nor anyone else may attempt to remove the cut material while the engine is running or the cutting equipment is rotating, as this can result in serious injury. Stop the engine and cutting equipment before you remove material that has wound around

OPERATION

the blade shaft as otherwise there is a risk of injury. The bevel gear can get hot during use and may remain so for a while afterwards. You could get burnt if you touch it.

WARNING: Watch out for thrown objects. Always wear approved eye protection. Never lean over the cutting attachment guard. Stones, rubbish, etc. can be thrown up into the eyes causing blindness or serious injury. Keep unauthorised persons at a distance. Children, animals, onlookers and helpers should be kept outside the safety zone of 50 ft (15 m). Stop the machine immediately if anyone approaches. Never swing the machine around without ﬁ rst checking behind you to make sure no-one is within the safety zone.

or cracked. Replace the blade guard if it is cracked.

• Check that the trimmer head and trimmer

guard are not damaged or cracked. Replace the trimmer head or trimmer guard if they have been cracked.

WARNING: Never use the machine without a guard or with a defective guard.

WARNING: The complete clutch cover and shaft must be ﬁ tted before the machine is started, otherwise the clutch can come loose and cause personal injury. Ensure the cutting attachment cannot come into contact with any object. Make sure no unauthorised persons are in the working area, otherwise there is a risk of serious personal injury. The safety distance is 50 ft (15 metres).

WARNING: Sometimes branches or grass get caught between the guard and cutting attachment. Always stop the engine before cleaning.

Check before starting

• Check the blade to ensure that no cracks have formed at the bottom of the teeth or by the centre hole. Discard a blade if cracks are found.

• Check that the support ﬂ ange is not cracked due to fatigue or due to being tightened too much. Discard the support ﬂ ange if it is cracked.

• Ensure the locking nut has not lost its captive force. The tightening torque of the locking screw should be 18 ftlb (25 Nm).

• Check that the blade guard is not damaged

Working methods

WARNING: Avoid cutting with the area of the blade between the 12 o’clock and 3 o’clock positions. Because of the speed of rotation of the blade kickout can occur if you attempt to cut thick stems with this area of the blade.

Forestry clearing

• Before you start clearing, check the clearing area, the type of terrain, the slope of the ground, whether there are stones, hollows etc.

• Start at whichever end of the area is easiest, and clear an open space from

OPERATION

which to work.

• Work systematically to and fro across the area, clearing a width of around 13-16 ft (4-5 m) on each pass. This exploits the full reach of the machine in both directions and gives the operator a convenient and varied working area to work in.

• Clear a strip around 250 ft (75 m) long. Move your fuel can as work progresses.

• On sloping ground you should work along the slope. It is much easier to work along a slope than it is to work up and down it.

• You should plan the strip so that you avoid going over ditches or other obstacles on the ground. You should also orient the strip to take advantage of wind conditions, so that cleared stems fall in the cleared area of the stand.

Grass clearing using a grass blade

• Grass blades and grass cutters must not be used on woody stems.

• A grass blade is used for all types of tall or coarse grass.

• The grass is cut down with a sideways, swinging movement, where the movement from right-to-left is the clearing stroke and the movement from left-to-right is the return stroke. Let the left-hand side of the blade (between 8 and 12 o’clock) do the cutting.

• If the blade is angled to the left when clearing grass, the grass will collect in a line, which makes it easier to collect, e.g. by raking.

• Try to work rhythmically. Stand ﬁ rmly with your feet apart. Move forward after the return stroke and stand ﬁ rmly again.

• Let the support cup rest lightly against the ground. It is used to protect the blade from hitting the ground.

• Reduce the risk of material wrapping around the blade by following these instructions:

1. Always work at full throttle.

2. Avoid the previously cut material during

the return stroke.

• Stop the engine, unclip the harness and place the machine on the ground before

you start to collect the cut material.

Grass trimming with a trimmer head

CAUTION: Do not work with mowing line longer than the intended diameter. With a properly mounted guard, the built-in cutter will automatically adjust the line to its proper length. Overly long lines can overload the engine, resulting in damage to the clutch mechanism and nearby parts.

Trimming

• Hold the trimmer head just above the ground at an angle. It is the end of the cord that does the work. Let the cord work at its own pace. Never press the cord into the area to be cut.

• The cord can easily remove grass and weeds up against walls, fences, trees and borders, however it can also damage sensitive bark on trees and bushes, and damage fence posts.

• Reduce the risk of damaging plants by shortening the cord to 4 - 4.7 in (10-12 cm) and reducing the engine speed.

Clearing

• The clearing technique removes all unwanted vegetation. Keep the trimmer head just above the ground and tilt it. Let the end of the cord strike the ground around trees, posts, statues and the like. (Fig. 14)

CAUTION: This technique increases the wear on the cord.

• The cord wears quicker and must be fed forward more often when working against stones, brick, concrete, metal fences, etc., than when coming into contact with trees and wooden fences.

• When trimming and clearing you should use less than full throttle so that the cord lasts longer and to reduce the wear on the trimmer head.

Cutting

• The trimmer is ideal for cutting grass that is difﬁ cult to reach using a normal lawn mower. Keep the cord parallel to the ground when cutting. Avoid pressing the trimmer head against the ground as this can ruin the lawn and damage the tool. (Fig. 15)

• Do not allow the trimmer head to constantly come into contact with the ground during normal cutting. Constant contact of this type can cause damage and wear to the trimmer head.

Sweeping

• The fan effect of the rotating cord can be used for quick and easy clearing up. Hold

OPERATION

the cord parallel to and above the area to be swept and move the tool to and fro. (Fig.

16)

• When cutting and sweeping you should use full throttle to obtain the best results.

WARNING: Never cut when visibility is poor or in very high or low temperatures or in freezing weather.

WARNING: If the cutting tool or deﬂ ector becomes clogged or stuck, always turn off the engine and make sure the cutting tool has stopped before cleaning. Grass, weeds, etc. should be cleaned off the cutting tool at regular intervals.

Cutting Attachment Maintenance

WARNING: It is absolutely essential to comply with the angles and dimensions speciﬁ ed below. If the blade is incorrectly sharpened there is a risk of increased kickout of the brush cutter and increase risk of thrown object, with resulting risk of injury. Failure to replace or repair damaged cutting attachment can cause serious injury. The blades are very sharp, always wear protective gloves when performing maintenance to the blades.

General rules

• Only use cutting attachments with

the guards we recommend! See

Recommended cutting attachments (Page 10).

• Keep the teeth of the blade correctly sharpened! Follow our instructions and use the recommended ﬁ le gauge. An incorrectly sharpened or damaged blade increases the risk of accidents. (Fig. 17)

• Check the cutting attachment for damage or cracks. A damaged cutting attachment should always be replaced.

• Resharpen frequently, take away as little material as possible – two or three strokes of the ﬁ le are usually enough.

MAINTENANCE

WARNING: Never repair damaged cutting attachments by welding, straightening or modifying the shape. This may cause parts of the cutting tool to come off and result in serious or fatal injuries.

Sharpening grass cutters and grass blades

• See the cutting attachment packaging for correct sharpening instructions. Sharpen blades and cutters using a single-cut ﬂ at ﬁ le.

• Sharpen all edges equally to maintain the balance of the blade. (Fig. 17)

Trimmer head

CAUTION: Always ensure the trimmer cord is wound tightly and evenly around the drum, otherwise the machine will generate harmful vibration.

To avoid out-of-balance:

• Resharpen the cutters uniformly – do not alter the contour of the parent blade in any way.

• After resharpening about 5 times, have blade checked by your dealer.

• Only use the recommended trimmer heads and trimmer cords. These have been tested by the manufacturer to suit a particular engine size. This is especially important when a fully automatic trimmer head is used. Only use the recommended cutting attachment. See Recommended cutting

attachments (Page 10).

MAINTENANCE

• Smaller machines generally require small trimmer heads and vice versa. This is because when clearing using a cord the engine must throw out the cord radially from the trimmer head and overcome the resistance of the grass being cleared.

• The length of the cord is also important. A longer cord requires greater engine power than a shorter cord of the same diameter.

• Make sure that the cutter on the trimmer guard is intact. This is used to cut the cord to the correct length.

• To increase the life of the cord it can be soaked in water for a couple of days. This will make the line tougher so that it lasts longer.

• Only use line of the same diameter as the original to avoid overloading the engine (Fig.18).

• In order to get more line out of the cutting head, tap it lightly on the ground while working. NOTE: never hit the nylon head against hard spots such as concrete or stones, it could be dangerous.

Replacing the nylon line on the UNIVERSAL trimmer head (Fig.27) DS 2200 TR: cut two pieces long 8 in (200

mm) of nylon line Ø 0.08 in (2.0 mm).

1. Inserting a line into the hole indicated with LINE (1) until it is released about 0.4 in (10 mm) from the opposite side (2).

2. Repeat operation with the other line (3).

from the opposite side (Fig.20.2).

2. Divide the line into two equal parts (Fig.

20.3) and then load the trimmer head by turning the knob (Fig. 20.4).

Carburetor Adjustment

Before adjusting the carburetor, clean the cover vents and air ﬁ lter as shown in Illustration Fig. 23, refer to Operation-Starting Unit and Maintenance-Air Filter Sections for details. Allow the engine to warm up prior to carburetor adjustment. This engine is designed and manufactured in order to comply with EPA (Environmental Protection Agency) Phase 3 regulations.

The carburetor (Fig. 21) is designed to permit only the adjustement of L and H screws in a range of 1/4 round; the ± 1/8 round the hall range admissible for L and H screws is determined by the manufacturer and you can not modify it.

WARNING: Don’t try to force the screws outside the range!

WARNING: Don’t modify the carburetor in any way in such case the engine will not run in compliance with emissions regulations.

Replacing the nylon line on the LOAD&GO trimmer head (Fig.20) DS 2200 S - DS 2200 T (Ø 4.3 in / 110 mm):

cut 13 ft (4 m) of nylon line Ø 0.09 in (2.4 mm). DS 2400 S - DS 2400 T (Ø 5.1 in / 130 mm): cut 28 ft (8.5 m) of nylon line Ø 0.09 in (2.4 mm).

1. Align the arrows and insert the line into the trimmer head (Fig. 20.1) until it is released

Idle Speed Adjustment

• If the engine starts, runs, and accelerates but will not idle; turn the idle speed screw

“T” clockwise to increase idle speed (Fig.

21).

• If the cutting attachment turns at idle, turn the idle speed screw “T” counter-clockwise to reduce the idle RPM and stop the cutting attachment movement. If the cutting attachment still moves at idle speed, contact
