Safety Precautions and Working Techniques

Because a special harvester is a high-speed power tool, special safety precautions must be observed to reduce the risk of personal injury.

It is important that you read, fully understand and observe the following safety precautions and warnings. Read the instruction manual and

the safety precautions periodically. Careless or improper use may cause serious or fatal injury.

Have your STIHL dealer show you how to operate your power tool. Observe all applicable local safety regulations, standards and ordinances.

Warning!

Do not lend or rent your power tool without the instruction manual. Be sure that anyone using it understands the information contained in this manual.

Warning!

Use your special harvester only for shaking small trees, branches, bushes and shrubs in order to harvest olives and certain other fruits and nuts. To reduce the risk of personal injury, do not use it for any other purpose.

Warning!

Minors should never be allowed to use this power tool. Bystanders, especially children, and animals should not be allowed in the area where it is in use.

Warning!

To reduce the risk of injury to bystanders and damage to property, never let your power tool run unattended. When it is not in use (e.g. during a work break), shut it off and make sure that unauthorized persons do not use it.

Most of these safety precautions and warnings apply to the use of all STIHL special harvesters. Different models may have different parts and controls. See the appropriate section of your instruction manual for a description of the controls and the function of the parts of your model.

Safe use of a special harvester involves

1. the operator
2. the power tool
3. the use of the power tool.

THE OPERATOR

Physical Condition

You must be in good physical condition and mental health and not under the influence of any substance (drugs, alcohol, etc.) which might impair vision, dexterity or judgment. Do not operate this machine when you are fatigued.

Warning!

Be alert – if you get tired, take a break. Tiredness may result in loss of control. Working with any power tool can be strenuous. If you have any condition that might be aggravated by strenuous work, check with your doctor before operating this machine.

Warning!

The ignition system of the STIHL unit produces an electromagnetic field of a very low intensity. This field may interfere with some pacemakers. To reduce the risk of serious or fatal injury, persons with a pacemaker should consult their physician and the pacemaker manufacturer before operating this tool.

Vibrations

Prolonged use of a power tool (or other machines) exposing the operator to vibrations may produce whitefinger disease (Raynaud's phenomenon) or carpal tunnel syndrome.

These conditions reduce the hand's ability to feel and regulate temperature, produce numbness and burning sensations and may cause nerve and circulation damage and tissue necrosis.

All factors which contribute to white-finger disease are not known, but cold weather, smoking and diseases or physical conditions that affect blood vessels and blood transport, as well as high vibration levels and long periods of exposure to vibration are mentioned as factors in the development of whitefinger disease. In order to reduce the risk of whitefinger disease and carpal tunnel syndrome, please note the following:

- Most STIHL power tools are available with an anti-vibration ("AV") system designed to reduce the transmission of vibrations created by the engine to the operator's hands. An AV system is recommended for those persons using power tools on a regular or sustained basis.

- Wear gloves and keep your hands warm.

• Keep the AV system well maintained. A power tool with loose components or with damaged or worn AV buffers will tend to have higher vibration levels.
• Maintain a firm grip at all times, but do not squeeze the handles with constant, excessive pressure. Take frequent breaks.

All the above-mentioned precautions do not guarantee that you will not sustain whitefinger disease or carpal tunnel syndrome. Therefore, continual and regular users should closely monitor the condition of their hands and fingers. If any of the above symptoms appear, seek medical advice immediately.

Warning

This power tool is equipped with an anti-vibration system. However, owing to the nature of the machine, this system cannot be as

effective in reducing the transmission of vibrations to the handles as normally achieved in other STIHL portable power tools.

Shaft movement and high engine speeds generate severe vibrations in this type of machine, particularly when it is run at full throttle during the shaking process. For this reason the unit should be operated only for short periods at a time and run at full throttle only during the shaking process. The shaking process itself should be kept as short as possible. Always utilize the proper grip. See the sections entitled "Holding and controlling the power tool" and "Operating instructions."

The permissible period of use is influenced by the following factors:

– Personal disposition to poor circulation – symptoms: frequent cold fingers, tingling sensations.
- Special personal stress factors – e.g. smoking, motorcycling in cold weather, use of other vibrating power tools, etc.
- Using the unit at low outside temperatures – STIHL recommends you wear gloves to keep your hands warm.
- The force with which the handles are held. Squeezing the handles of the special harvester with constant, excessive pressure restricts blood circulation and is unfavorable.
– Frequency of breaks – taking regular work breaks is better than long periods of uninterrupted operation.

Therefore, the permissible period of actual use for any one operator should be strictly limited and should not exceed one-and-a-half hours per day.

If the unit is to be operated for longer than one-and-a-half hours per workday, the operators in a work group should share the work by rotating at regular intervals, so that no one operator exceeds the above-mentionend limit.

Warning!

Seek medical advice immediately if any of the symptoms described above appear after prolonged and regular use of the machine. Operators with such symptoms should not use the machine until they have consulted their doctor.

Proper Clothing

Warning!

To reduce the risk of injury, the operator should wear proper protective apparel.

Warning!

To reduce the risk of injury to your eyes never operate your power tool unless wearing goggles or properly fitted protective glasses with adequate top and side protection complying with ANSI Z 87.1 (or your applicable national standard). To reduce the risk of injury to your face STIHL recommends that you also wear a face shield or face screen over your goggles or protective glasses.

Warning!

Power tool noise may damage your hearing. Wear sound barriers (ear plugs or ear mufflers) to protect your hearing. Continual and regular users should have their hearing checked regularly.

Be particularly alert and cautious when wearing hearing protection because your ability to hear warnings (shouts, alarms, etc.) is restricted.

Always wear gloves when handling the machine. Heavy-duty, nonslip gloves improve your grip and help to protect your hands.

Clothing must be sturdy and snug-fitting, but allow complete freedom of movement. Wear long pants made of heavy material to help protect your legs. Do not wear shorts, sandals or go barefoot.

Avoid loose-fitting jackets, scarfs, neckties, jewelry, flared or cuffed pants, unconfined long hair or anything that could become caught on

branches, brush or the moving parts of the unit. Secure hair so it is above shoulder level.

Good footing is very important. Wear sturdy shoes or boots with nonslip soles. Steel-toed safety boots are recommended.

Wear an approved safety hard hat to reduce the risk of injury to your head when there is a danger of head injuries.

STIHL offers a wide range of protective clothing and equipment.

THE POWER TOOL

For illustrations and definitions of the power tool parts see the chapter on "Main Parts and Controls."

Warning!

Never modify this power tool in any way. Only attachments supplied by STIHL or expressly approved by STIHL for use with the specific STIHL model are authorized. Although certain unauthorized attachments are useable with STIHL power tools, their use may, in fact, be extremely dangerous.

If this tool is subjected to unusually high loads for which it was not designed (e.g. heavy impact or a fall), always check that it is in good condition before continuing work. Check in particular that the fuel system is tight (no leaks) and that the controls and safety devices are working properly. Do not continue operating this machine if it is damaged. In case of doubt, have it checked by your STIHL servicing dealer.

THE USE OF THE POWER TOOL Transporting the Power Tool

Carry the unit suspended from the harness. Keep the hot muffler away from your body and the hook behind you.

Warning!

Always switch off the engine and make sure the hook has stopped moving before putting the machine down. When transporting it in a vehicle, properly secure it to prevent turnover, fuel spillage and damage to the power tool.

Fuel

Your STIHL power tool uses an oil-gasoline mixture for fuel (see the chapter on "Fuel" of your instruction manual).

Warning!

Gasoline is an extremely flammable fuel. If spilled and ignited by a spark or other ignition source, it can cause fire and serious burn injury or property

damage. Use extreme caution when handling gasoline or fuel mix. Do not smoke or bring any fire or flame near the fuel or the power tool. Note that combustible fuel vapor may escape from the fuel system.

Fueling Instructions

Warning!

Fuel your power tool in well-ventilated areas, outdoors. Always shut off the engine and allow it to cool before refueling. Gasoline vapor pressure may build up inside the fuel tank depending on the fuel used, the weather conditions and the tank venting system.

In order to reduce the risk of burns and other personal injury from escaping gas vapor and fumes, remove the fuel filler cap on your power tool carefully so as to allow any pressure build-up in the tank to release slowly. Never remove the fuel filler cap while the engine is running.

Select bare ground for fueling and move at least 10 feet (3 m) from the fueling spot before starting the engine. Wipe off any spilled fuel before starting your machine.

Warning!

Check for fuel leakage while refueling and during operation. If fuel leakage is found, do not start or run the engine until the leak is fixed and any spilled fuel has been wiped away. Take care not to get fuel on your clothing. If this happens, change your clothing immediately.

Different models may be equipped with different fuel caps.

Cap with grip

Warning!

In order to reduce the risk of fuel spillage and fire from an improperly tightened fuel cap, correctly position and tighten the fuel cap in the fuel tank opening.

To do this with this STIHL cap, raise the grip on the top of the cap until it is upright at a 90° angle. Insert the cap in the fuel tank opening with the

triangular marks on the grip of the cap and on the fuel tank opening lining up. Using the grip, turn the cap firmly clockwise as far as it will go (approx. a quarter turn).

Fold the grip flush with the top of the cap. If the grip does not lie completely flush with the cap and the detent on the grip does not fit in the

corresponding recess in the filler neck, the cap is not properly seated and tightened and you must repeat the above steps.

Screw cap

Warning!

Unit vibrations can cause an improperly tightened fuel filler cap to loosen or come off and spill quantities of fuel. In order to reduce the risk of fuel spillage and fire, tighten the fuel filler cap by hand as securely as possible.

Before Starting

Warning!

Always check your power tool for proper condition and operation before starting, particularly the throttle trigger, throttle trigger interlock, stop switch and harness. The throttle trigger must move freely and always spring back to the idle position. Never attempt to modify the controls or safety devices.

Warning!

Never use a power tool that is damaged or not properly maintained.

Warning!

Check that the spark plug boot is securely mounted on the spark plug – a loose boot may cause arcing that could ignite combustible fumes and cause a fire.

Keep the handles clean and dry at all times; it is particularly important to keep them free of moisture, pitch, oil, grease or resin in order for you to maintain a firm grip and properly control your power tool.

Warning!

To reduce the risk of injury from breakage and loss of control, never use your unit if the hook or shaft is damaged or cracked. Never attempt to repair a damaged or cracked hook or shaft by welding or straightening.

Adjust the carrying harness and hand grip to suit your size before starting work. To be better prepared in case of an emergency, practice releasing the unit from the harness as quickly as possible.

Starting

Start the engine at least 10 feet (3 meters) from the fueling spot, outdoors only.

Line drawing of a person using a power tool on a construction site (no text or symbols)

For specific starting instructions, see the appropriate section of your manual. Place the power tool on firm ground or other solid surface in an open area. Maintain good balance and secure footing.

Warning!

To reduce the risk of injury from loss of control when starting, be absolutely sure that the hook is clear of you and all other obstructions and objects, including the ground, because when the engine starts at starting-throttle, engine speed will be fast enough for the clutch to engage and the hook to move.

With the engine running only at idle, attach the power tool to the spring hook of your harness (see appropriate chapter of this manual).

Warning!

Your power tool is a one-person machine. Do not allow other persons in the general work area, even when starting.

Warning!

To reduce the risk of injury from loss of control, do not attempt to "drop start" your power tool.

Warning!

When you pull the starter grip, do not wrap the starter rope around your hand. Do not let the grip snap back, but guide the starter rope to rewind it properly. Failure to follow this procedure may result in injury to your hand or fingers and may damage the starter mechanism.

Important Adjustments

Warning!

To reduce the risk of personal injury from loss of control or contact with the moving hook, do not use your unit with incorrect idle adjustment. At correct idle speed, the hook should not move. For directions on how to adjust idle speed, see the appropriate section of your instruction manual.

If you cannot set the correct idle speed, have your STIHL dealer check your power tool and make proper adjustments and repairs.

During Operation

Holding and controlling the power tool

Always hold the unit properly while you are working. When moving between shaking applications and when positioning or repositioning the hook, hold the power tool with your right hand firmly on the control handle and your left hand on the padded grip area of the shaft to maintain proper control. Wrap your fingers and thumbs around the handles. This also applies to left-handers.

During the actual shaking process, you should grip the machine differently because of the intense vibrations transmitted to the handles, especially to the handle hose on the shaft itself.

Line drawing of a person using a handheld device with attached straps (no text or symbols)

When accelerating the engine in order to apply the shaking motion after the hook has been positioned on the stem or branch, always hold the power tool only with your right hand loosely on the control handle, keeping your left hand free of the shaft. When the shaking application is complete, let the power tool return to idle before putting your left hand back on the shaft and repositioning the hook. (See also the vibration warnings in the "Vibrations" and "Operating Instructions" sections of these safety precautions.)

Warning!

Do not overreach. Keep proper footing and balance at all times. Special care must be taken in slippery conditions (dampness, fruit on the ground) and in difficult, overgrown terrain. Watch out for hidden obstacles such as tree stumps, roots and ditches to avoid stumbling. Be extremely cautious when working on slopes or uneven ground.

Warning

To reduce the risk of injury from loss of control, never work on a ladder, in a tree or any other insecure support.

Working conditions

Operate and start your power tool only outdoors in a well ventilated area. Operate it under good visibility and daylight conditions only. Work carefully.

Warning!

As soon as the engine is running, this product generates toxic exhaust fumes containing chemicals (such as unburned hydrocarbons

and carbon monoxide) known to cause respiratory problems, cancer, birth defects, or other reproductive harm. Some of the gases (e.g. carbon monoxide) may be colorless and odorless. To reduce the risk of serious or fatal injury/illness from inhaling toxic fumes, never run the machine indoors or in poorly ventilated locations.

Warning!

If the trees, branches, bushes or shrubs being shaken, or the surrounding ground is coated with a chemical substance (such as an active pesticide or herbicide), read and follow the instructions and warnings that accompanied the substance at issue.

Warning!

Inhalation of certain dusts, especially organic dusts such as mold or pollen, can cause susceptible persons to have an allergic or asthmatic reaction. Substantial or repeated inhalation of dust and other airborne contaminants, in particular those with a smaller particle size, may cause respiratory or other illnesses. Control dust at the source where possible. Use good work practices, such as operating the unit so that the wind or operating process directs any dust raised by the power tool away from the operator. Follow the recommendations of EPA/OSHA/NIOSH and occupational and trade associations with respect to dust (“particulate matter”). When the inhalation of dust cannot be substantially controlled, i.e., kept at or near the ambient (background) level, the operator and any bystanders should wear a respirator approved by NIOSH/MSHA for the type of dust encountered.

Operating instructions

Warning!

Do not operate your power tool using the starting throttle lock, as you do not have control of the engine speed.

In the event of an emergency, switch off the engine immediately – move the slide control / stop switch to 0 or STOP.

Warning

The hook continues to move for a short period after the throttle trigger is released (flywheel effect).

Warning!

Accelerating the engine while movement of the hook is blocked increases the load on the engine and will cause the clutch to slip continuously. This may result in overheating and damage to important components (e.g. clutch, polymer housing components), which can then increase the risk of injury from the hook moving while the engine is idling.

Warning!

To reduce the risk of injury to the operator from vibrations, the unit should be run at full throttle only during the shaking process. In addition, and in order to reduce the likelihood of damage to the stems and branches being shaken, the shaking process itself should be kept as short as possible. Depress the throttle trigger in a short burst or a series of short bursts to apply the shaking motion.

Remember to hold the power tool only with your right hand loosely on the control handle during the shaking process. See the section on “Holding and controlling the power tool” above.

Work calmly and carefully – in daylight conditions and only when visibility is good. Stay alert at all times so as not to endanger others.

Warning!

In order to reduce the risk of serious or even fatal injury to bystanders from falling objects or inadvertent contact with the moving parts of your power tool always keep bystanders out of the reach of the machine.

Danger!

Your power tool is not insulated against electric shock. To reduce the risk of electrocution, never

operate this power tool in the vicinity of any wires or cables (power, etc.) which may be carrying electric current.

Warning

The gearbox becomes hot during operation. To reduce the risk of burn injury, do not touch the gear housing when it is hot.

Warning!

The muffler and other parts of the engine (e.g. fins of the cylinder, spark plug) become hot during operation and remain hot for a while after stopping the engine. To reduce risk of burns do not touch the muffler and other parts while they are hot.

Warning!

To reduce the risk of fire and burn injury, keep the area around the muffler clean. Remove excess lubricant and all debris such as pine needles, branches or leaves. Let the engine cool down sitting on concrete, metal, bare ground or solid wood (e.g. the trunk of a felled tree) away from any combustible substances.

Warning!

Never modify your muffler. The muffler could be damaged and cause an increase in heat radiation or sparks, thereby increasing the risk of fire and burn injury. You may also permanently damage the engine. Have your muffler serviced and repaired by your STIHL servicing dealer only.

Catalytic converter

Warning!

Some STIHL power tools are equipped with a catalytic converter, which is designed to reduce the exhaust emissions of the engine by a chemical process in the muffler. Due to this process, the muffler does not cool down as rapidly as conventional mufflers when the engine returns to idle or is shut off. To reduce the risk of fire and burn injuries, the following specific safety precautions must be observed.

Warning!

Since a muffler with a catalytic converter cools down less rapidly than conventional mufflers, always set your power tool down in the upright position and never locate it where the muffler is near dry brush, grass, wood chips or other combustible materials while it is still hot.

Warning!

An improperly mounted or damaged cylinder housing or a damaged/ deformed muffler shell may interfere with the cooling process of the catalytic converter. To reduce the risk of fire or burn injury, do not continue work with a damaged or improperly mounted cylinder housing or a damaged/ deformed muffler shell.

Your catalytic converter is furnished with screens designed to reduce the risk of fire from the emission of hot particles. Due to the heat from the catalytic reaction, these screens will normally stay clean and need no service or maintenance. If you experience loss of performance and you suspect a clogged screen, have your muffler maintained by a STIHL servicing dealer.

MAINTENANCE, REPAIR AND STORING

Maintenance, replacement, or repair of the emission control devices and systems may be performed by any nonroad engine repair establishment or individual. However, if you make a warranty claim for a component which has not been serviced or maintained properly or if nonapproved replacement parts were used, STIHL may deny coverage.

⚠ Warning!

Use only identical STIHL replacement parts for maintenance and repair. Use of non STIHL parts may cause serious or fatal injury.

Strictly follow the maintenance and repair instructions in the appropriate section of your instruction manual. Please refer to the maintenance chart in this manual.

⚠ Warning!

Always stop the engine before doing any maintenance or repair work or cleaning the power tool. Do not attempt any maintenance or repair work not described in your instruction manual. Have such work performed by your STIHL servicing dealer only.

Warning!

Use the specified spark plug and make sure it and the ignition lead are always clean and in good condition. Always press spark plug boot snugly onto spark plug terminal of the proper size. (Note: If terminal has detachable SAE adapter nut, it must be attached.) A loose connection between spark plug boot and the ignition wire connector in the boot may create arcing that could ignite combustible fumes and cause a fire.

Warning!

Never test the ignition system with the ignition wire boot removed from the spark plug or with a removed spark plug, since uncontained sparking may cause a fire.

Warning

Do not operate your power tool if the muffler is damaged, missing or modified. In improperly maintained muffler will increase the risk of fire and hearing loss.

If your muffler was equipped with a spark-arresting screen to reduce the risk of fire, never operate your power tool if the screen is missing or damaged. Remember that the risk of forest fires is greater in hot or dry weather.

Warning!

Never repair damaged parts by welding, straightening or modifying the shape. This may cause them to break or come off, resulting in loss of control and serious or fatal injuries.

Tighten all nuts, bolts and screws, except the carburetor adjustment screws, after each use.

Store the power tool in a dry and high or locked location out of reach of children.

Before storing for longer than a few days, always empty the fuel tank. See chapter "Storing the machine" in this manual.

Fuel

- Press down the trigger interlock (1) and squeeze the throttle trigger (2) all the way (full throttle position) – this sets the throttle cable correctly.

This engine is certified to operate on unleaded gasoline and the STIHL two-stroke engine oil at a mix ratio of 50:1.

Your two-stroke engine requires a mixture of high-quality gasoline and quality two-stroke air cooled engine oil.

Use mid-grade unleaded gasoline with a minimum octane rating of 89 (R+M/2). If the octane rating of the mid-grade gasoline in your area is lower, use premium unleaded fuel.

Fuel with a lower octane rating may increase engine temperatures. This, in turn, increases the risk of piston seizure and damage to the engine.

The chemical composition of the fuel is also important. Some fuel additives not only detrimentally affect elastomers (carburetor diaphragms, oil seals, fuel lines, etc.), but magnesium castings and catalytic converters as well. This could cause running problems or even damage the engine. For this reason STIHL recommends that you use only nationally recognized high-quality unleaded gasoline!

Use only STIHL two-stroke engine oil or equivalent high-quality two-stroke engine oils that are designed for use only in air cooled two-cycle engines.

We recommend STIHL 50:1 two-stroke engine oil since it is specially formulated for use in STIHL engines.

Do not use BIA or TCW rated (two-stroke water cooled) mix oils or other mix oils that state they are for use in both water cooled and air cooled engines (e.g., outboard motors, snowmobiles, chainsaws, mopeds, etc.).

Take care when handling gasoline. Avoid direct contact with the skin and avoid inhaling fuel vapor. When filling at the pump, first remove the canister from your vehicle and place the canister on the ground before filling. Do not fill fuel canisters that are sitting in or on a vehicle.

The canister should be kept tightly closed in order to avoid any moisture getting into the mixture.

The machine's fuel tank and the canister in which fuel mix is stored should be cleaned as necessary.

Fueling

Fuel mix ages

Only mix sufficient fuel for a few days work, not to exceed 3 months of storage. Store in approved fuel-canisters only. When mixing, pour oil into the canister first, and then add gasoline. Close the canister and shake it vigorously by hand to ensure proper mixing of the oil with the fuel.

The split drive tube enables the machine to be disassembled for easier transportation.

Separating the Drive Tubes

• Disconnect the harness from the carrying rings.
  ●Place the machine on the ground so that it rests on the engine support and the hook.
  ●Turn the hook so that its open side points vertically downward.

Operating Instructions

●Hold the hook steady with the 36 mm open-end wrench (1) and, at the same time, use the 47 mm wrench (2) to loosen the nut (3) at the engine end of the drive tube. Unscrew the nut from the thread.
- Separate the drive tubes. Push the cap (4) onto the front end of the drive tube.
It is important to keep the ends of the drive tube clean.

Connecting the Drive Tubes

• Remove the cap from the front end of the drive shaft and keep it in a safe place.
  ●Place the machine on the ground so that it rests in the engine support.
  ●Inspect the ends of drive tubes for dirt and clean if necessary.
  ●Push the front end of the drive tube as far as stop onto the drive tube at the engine end.
• Rotate the front of the drive tube until until the open side of the hook points vertically downward – use the 36 mm open-end wrench to hold the hook steady for the following operations.
  ●Screw the nut onto the thread and tighten it down firmly with the 47 mm open-end wrench.
  The open side of the hook must now point vertically downward. If not, repeat the steps described above.
• Check swivel range of hook – see "User Checks and Maintenance".
• Attach the harness to the carrying rings.

During break-in period

A factory new machine should not be run at high revs (full throttle off load) for the first three tank fillings. This avoids unnecessary high loads during the break-in period. As all moving parts have to bed in during the break-in period, the frictional resistances in the engine are greater during this period. The engine develops its maximum power after about 5 to 15 tank fillings.

During operation

After a long period of full-throttle operation, allow engine to run for a while at idle speed so that the heat in the engine can be dissipated by flow of cooling air. This protects engine-mounted components (ignition, carburetor) from thermal overload.

After finishing work

Wait for engine to cool down. Drain the fuel tank. Store the machine in a dry place. Check tightness of nuts and screws (not adjusting screws) at regular intervals and retighten as necessary.

Cleaning the Air Filter

Dirty air filters reduce engine power, increase fuel consumption and make starting more difficult.

If there is a noticeable loss of engine power:

• Set the choke knob to
• Press in the tab (1) and remove the filter cover (2).
  ●Clean away loose dirt from inside the cover and around the filter (3).

Motor Management

• Remove the filter element and inspect it – replace if dirty or damaged – do not clean.
  ●Install filter element in the cover.
  ●Refit the filter cover.

Exhaust emissions are controlled by the design of the fundamental engine parameters and components (e.g. carburation, ignition, timing and valve or port timing) without the addition of any major hardware.

Adjusting the Carburetor

General Information

The carburetor comes from the factory with a standard setting.

This setting provides an optimum fuel-air mixture under most operating conditions.

With this carburetor it is only possible to adjust the high speed screw within fine limits.

Adjustments may only be performed when the machine is completely and securely assembled.

Standard Setting

●Shut off the engine.
- Check the air filter and replace if necessary.
- Check adjustment of throttle cable and readjust if necessary – see "Adjusting the Throttle Cable".

Turn the high speed screw (H) counterclockwise as far as stop - max. ^3/_4 turn

●Carefully turn the low speed screw (L) down onto its seat clockwise. Then open it one turn counterclockwise.
●Start and warm up the engine.
- Adjust idle speed with the idle speed screw (LA) so that the hook does not move.

Fine Tuning for Different Operating Conditions

A slight correction of the setting of the high speed screw (H) may be necessary if engine power is not satisfactory when operating at high altitude or at sea level.

Rule of thumb

Turn the high speed screw (H) about one eighth turn for every 3300 ft (1000m) change in altitude.

Conditions for adjustment

●Carry out standard setting.
●Warm up the engine for about 5 minutes.
- Open the throttle wide.

At high altitude

- Turn the high speed screw (H) clockwise (leaner), no further than stop, until there is no noticeable increase in engine speed.

Checking the Spark Plug

At sea level

- Turn the high speed screw (H) counterclockwise (richer), no further than stop, until there is no noticeable increase in engine speed.

⚠ It is possible that maximum engine speed may be reached with the standard setting in each case.

Adjusting Idle Speed

It is usually necessary to change the setting of the idle speed screw (LA) after every correction to the low speed screw (L).

●Warm up the engine.

Engine stops while idling

- Turn idle speed screw (LA) slowly clockwise until the engine runs smoothly – hook must not move.

Hook runs when engine is idling

- Turn idle speed screw (LA) slowly counterclockwise until hook stops moving and then turn the screw about another 1/2 to 1 turn in the same direction.

Erratic idling behavior, engine stops even though setting of LA screw is correct, poor acceleration

Idle setting too lean:

- Turn the low speed screw (L) counterclockwise (about 1/4 turn) until the engine runs and accelerates smoothly.

Erratic idling behavior

Idle setting too rich:

- Turn low speed screw (L) clockwise (about 1/4 turn) until the engine runs and accelerates smoothly.

Wrong fuel mix (too much engine oil in the gasoline), a dirty air filter and unfavorable running conditions (mostly at part throttle etc.) affect the condition of the spark plug. These factors cause deposits to form on the insulator nose which may result in trouble in operation.

Engine Running Behavior

If engine is down on power, difficult to start or runs poorly at idling speed, first check the spark plug.

• Remove spark plug as described in chapter "Starting / Stopping the Engine".
  ●Clean dirty spark plug.
• Check the electrode gap (A) and readjust if necessary – see "Specifications".
  ●Use only resistor type spark plugs of the approved range.

Rectify problems which have caused fouling of spark plug:

●Too much oil in fuel mix.
●Dirty air filter.
●Unfavorable running conditions, e.g. operating at part load.

Fit a new spark plug after approx. 100 operating hours

or earlier if the electrodes are badly eroded.

If engine running behavior is unsatisfactory even though the air filter is clean and the carburetor and throttle cable are properly adjusted, the cause may be in the muffler.

Have your STIHL dealer inspect the muffler for carbonization.

STIHL recommends that maintenance and repair work be carried out only by authorized STIHL dealers.

To reduce the risk of fire and burn injury, use only spark plugs authorized by STIHL. Always press spark plug boot (2) snugly onto terminal (1) of the proper size. (Note: If terminal has detachable SAE adapter nut, it must be attached.) A loose connection between spark plug boot and ignition wire connector in the boot may create arcing that could ignite combustible fumes and cause a fire.

Replacing Starter Rope and Rewind Spring

Replacing a Broken Starter Rope

⚠ The rewind spring may pop out and uncoil during this operation. Take care to avoid injury.

• Remove the screws (1).
  ●Lift away the fan housing.

• Remove the spring clip (2).
  ●Carefully remove the rope rotor with washer (3) and pawl (4).

• Ease the cap (5) out of the starter grip.

• Remove remaining rope from the rotor and grip.
  ●Tie a simple overhand knot in the new rope – see "Specifications" – and then thread it through the top of the grip and the rope bush (6).
  ●Refit the cap in the grip.

●Thread the rope through the rotor and secure it with a simple overhand knot.
- Coat rope rotor bearing bore with non-resinous oil – see "Special Accessories".
- Slip rotor over starter post – turn it back and forth to engage anchor loop of rewind spring.
●Refit the pawl (4).
●Fit the washer (3).
- Install spring clip (2) on starter post and engage it on the pawl's peg – the spring clip must point clockwise.

Tensioning the Rewind Spring

●Make a loop in the unwound starter rope and use it to turn the rope rotor six full revolutions counterclockwise.
- Hold the rotor steady – pull out and straighten the twisted rope.
●Release the rope rotor.

• Let go of rope slowly so that it winds onto the rotor.
  The starter grip must locate firmly in the rope guide bush. If the grip droops to one side: Add one more turn on rope rotor to increase spring tension.

When the starter rope is fully extended it must still be possible to rotate the rotor another 1 1/2 turns.

If this is not the case, the spring is overtensioned and could break.

●Take one turn of rope off the rotor in such a case.
●Fit the fan housing.

Replacing a Broken Rewind Spring

• Remove the rope rotor as described under "Replacing a Broken Starter Rope".
  The bits of spring in the fan housing might still be under tension and could fly apart when you take them out of the housing. To reduce risk of injury, wear eye and face protection and work gloves.

● Take out the screws (7).
- Remove the spring housing and parts of spring.
- Lubricate replacement spring in new spring housing with a few drops of non-resinous oil – see "Special Accessories".

Place the replacement spring with housing in position – bottom plate must face up. If the spring pops out of the housing during installation: Refit it in the clockwise direction, starting outside and working inward.

●Fit the screws.
●Install the rope rotor as described under "Replacing a Broken Starter Rope".
●Tension the rewind spring.
●Fit the fan housing.

Storing the Machine User Checks and Maintenance

For periods of about 3 months or longer:

●Drain and clean the fuel tank in a well ventilated area.
●Dispose of remaining fuel and cleaning solution properly in accordance with local environmental requirements.
- Run engine until carburetor is dry – this helps prevent carburetor diaphragms sticking together.
●Thoroughly clean the machine – pay special attention to the cylinder fins and air filter.
- Store the machine in a dry, high or locked location – out of the reach of children and other unauthorized persons.

Checking Swivel Range of Hook

●Place the machine on the ground so that it rests horizontally on the engine support.
●Turn the front end of the drive tube between the left and right stops. The hook must swing through a range of 270^ .

It must be possible to swing the hook equidistant to the right and left from its vertical centerline. If this is not the case, repeat the steps described in "Assembling the Unit".

Visual Inspection

●Carry out a full visual inspection of the whole machine before each use and after every refueling stop.

Screws and Nuts

- Check tightness of all accessible screws and nuts (not adjusting screws) after about every 25 hours of operation. Important: Check security of drive tube screw unions – see "Assembling the Unit".
