INTRODUCTION
Dear Customer,
Thank you for choosing a McCulloch product.You are thereby part of a story that started long ago, when the McCulloch Corporation started its manufacturing of engines during World War II. In 1949, when McCulloch introduced its first light one-man chainsaw, woodworking would never be the same again.
The line of innovative chainsaws would continue over the decades, and business was expanded, first by airplane and kart engines in the 1950s, then by mini chainsaws in the 1960s. Later, in the 1970s and 80s, trimmers and blower vacs were added to the range.
Today, as a part of the Husqvarna group, McCulloch continues the tradition of powerful engines, technical innovations, and strong designs that have been our hallmarks for more than half a century. Lowering fuel consumption, emissions and noise levels are of top priority to us, as is improving safety and user-friendliness.
We certainly hope that you will be satisfied with your McCulloch product, as it is designed to be your companion for a long time. By following this operators manual’s advice on usage, service, and maintenance, its lifespan can be extended. If you should need professional help with repair or service, please use the Service Locator at www.mcculloch.com.
McCulloch has a policy of continuous product development and therefore reserves the right to modify the design and appearance of products without prior notice.
This manual can also be downloaded at www.mcculloch.com.

Never use a machine that is faulty. Carry out the safety checks, maintenance and service instructions described in this manual. Some maintenance and service measures must be carried out by trained and qualified specialists. See instructions under the
Maintenance heading.
All covers, guards and handles must be fitted before starting. Ensure that the spark plug cap and ignition lead are undamaged to avoid the risk of electric shock.
The machine operator must ensure that no people or animals come closer than 15 meters while working. When several operators are working in the same area the safety distance should be at least twice the tree height and no less than 15 meters.
National or local regulations may regulate the use. Comply to given regulations.
Carry out an overall inspection of the machine before use. See the maintenance schedule.
WARNING! This machine produces an ! electromagnetic field during operation.
This field may under some circumstances interfere with active or passive medical implants.To reduce the risk of serious or fatal injury, we recommend persons with medical implants to consult their physician and the medical implant manufacturer before operating this machine.
WARNING! Running an engine in a ! confined or badly ventilated area can
result in death due to asphyxiation or carbon monoxide poisoning.
WARNING! Never allow children to use or
! be in the vicinity of the machine. As the machine is equipped with a springloaded stop switch and can be started by low speed and force on the starter handle, even small children under some circumstances can produce the force necessary to start the machine. This can mean a risk of serious personal injury. Therefore remove the spark plug cap when the machine is not under close supervision.
Personal protective equipment
IMPORTANT!
A grass trimmer can be dangerous if used incorrectly or carelessly, and can cause serious or fatal injury to the operator or others. It is extremely important that you read and understand the contents of this operator’s manual.
You must use approved personal protective equipment whenever you use the machine. Personal protective equipment cannot eliminate the risk of injury but it will reduce the degree of injury if an accident does happen. Ask your dealer for help in choosing the right equipment.
WARNING! Listen out for warning signals ! or shouts when you are wearing hearing protection. Always remove your hearing protection as soon as the engine stops.
HELMET
Wear a protective helmet where there is a risk of falling objects
HEARING PROTECTION
Wear hearing protection that provides adequate noise reduction.

GENERAL SAFETY PRECAUTIONS
GLOVES
Gloves should be worn when necessary, e.g. when fitting cutting attachments.
BOOTS
Wear boots with steel toe-caps and non-slip sole.
CLOTHING
Wear clothes made of a strong fabric and avoid loose clothing that can catch on twigs and branches. Always wear heavy, long pants. Do not wear jewellery, shorts sandals or go barefoot. Secure hair so it is above shoulder level.
FIRST AID KIT
Always have a first aid kit nearby.
Machine′s safety equipment
This section describes the machine′s safety equipment, its purpose, and how checks and maintenance should be carried out to ensure that it operates correctly. See the ”What is what?” section to locate where this equipment is positioned on your machine.
The life span of the machine can be reduced and the risk of accidents can increase if machine maintenance is not carried out correctly and if service and/or repairs are not carried out professionally. If you need further information please contact your nearest service workshop.
IMPORTANT!
All servicing and repair work on the machine requires special training. This is especially true of the machine′s safety equipment. If your machine fails any of the checks described below you must contact your service agent. When you buy any of our products we guarantee the availability of professional repairs and service. If the retailer who sells your machine is not a servicing dealer, ask him for the address of your nearest service agent.
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 lockout
The throttle lockout is designed to prevent accidental operation of the throttle control. When you press the lock
(A) (i.e. when you grasp the handle) it releases the throttle control (B). When you release the handle the throttle control and the throttle lockout both move back to their original positions. This movement is controlled by two independent return springs.This arrangement means that the throttle control is automatically locked at the idle setting.
A
B
Make sure the throttle control is locked at the idle setting when the throttle lockout is released.
Press the throttle lockout and make sure it returns to its original position when you release it.
Check that the throttle trigger and throttle lockout move freely and that the return springs work properly.
See instructions under the heading Start. Start the machine and apply full throttle. Release the throttle and check that the cutting attachment stops and remains at a standstill. If the cutting attachment rotates with the throttle in the idle position then the carburettor idle setting must be checked. See instructions under the heading Maintenance.

GENERAL SAFETY PRECAUTIONS
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
In countries that have a warm and dry climate there is a significant risk of fire.We therefore fit certain mufflers with a spark arrestor mesh. Check whether the muffler on your machine is fitted with this kind of mesh.
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 chapter on Technical data. If an incorrect or faulty guard is fitted this can cause serious personal injury.
Muffler
The muffler is designed to keep noise levels to a minimum and to direct exhaust fumes away from the user. A muffler fitted with a catalytic converter is also designed to reduce harmful exhaust gases.
For mufflers it is very important that you follow the instructions on checking, maintaining and servicing your machine.
Never use a machine that has a faulty muffler.
Regularly check that the muffler is securely attached to the machine.
If the muffler on your machine is fitted with a spark arrestor mesh this must be cleaned regularly. A blocked mesh will cause the engine to overheat and may lead to serious damage.
WARNING! Mufflers fitted 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 fire!
WARNING! The inside of the muffler
! contain chemicals that may be carcinogenic. Avoid contact with these elements in the event of a damaged muffler.
! |
WARNING! Bear in mind that: |
|
The exhaust fumes from the engine are hot and may contain sparks which can start a fire. Never start the machine indoors or near combustible material!

GENERAL SAFETY PRECAUTIONS
Locking nut
A locking nut is used to secure some types of cutting attachment.
When fitting, tighten the nut in the opposite direction to the direction of rotation of the cutting attachment. To remove it, undo the nut in the same direction as the cutting attachment rotates. (CAUTION! The nut has a left-hand thread.) Tighten the nut using the socket spanner.
Cutting equipment
This section describes how to choose and maintain your cutting equipment in order to:
•Reduce the risk of blade thrust.
•Obtain maximum cutting performance.
•Extend the life of cutting equipment.
IMPORTANT!
Only use cutting attachments with the guards we recommend! See the chapter on Technical data.
Refer to the instructions for the cutting attachment to check the correct way to load the cord and the correct cord diameter.
Keep the teeth of the blade correctly sharpened! Follow our recommendations. Also refer to the instructions on the blade packaging.
WARNING! Always stop the engine
! before doing any work on the cutting 
attachment.This continues to rotate even
after the throttle has been released.
Ensure that the cutting attachment has stopped completely and disconnect the spark plug cap before you start to work on it.
WARNING! Using an incorrect cutting
! attachment or an incorrectly sharpened blade increases the risk of blade thrust.
Cutting equipment
Grass blades and grass knifes are intended for cutting coarse grass.
A trimmer head is intended for trimming grass.
General rules
Only use cutting attachments with the guards we recommend! See the chapter on Technical data.
Keep the teeth of the blade correctly sharpened! Follow our instructions and use the recommended file gauge. An incorrectly sharpened or damaged blade increases the risk of accidents.
Check the cutting attachment for damage or cracks. A damaged cutting attachment should always be replaced.
English – 9
GENERAL SAFETY PRECAUTIONS
Sharpening grass knifes and grass blades
•See the cutting attachment packaging for correct sharpening instructions. Sharpen blades and knifes using a single-cut flat file.
•Sharpen all edges equally to maintain the balance of the blade.
WARNING! Always discard a blade that is
! bent, twisted, cracked, broken or damaged in any other way. Never attempt to straighten a twisted blade so that it can be reused. Only use original blades of the specified type.
Trimmer head
IMPORTANT!
Always ensure the trimmer cord is wound tightly and evenly around the drum, otherwise the machine will generate harmful vibration.
•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 the chapter on Technical data.
•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 before use. This will make the cord tougher so that it lasts longer.

FUEL HANDLING
Fuel safety
Never start the machine:
1If you have spilled fuel on it. Wipe off the spillage and allow remaining fuel to evaporate.
2If you have spilled 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.
3If the machine is leaking fuel. Check regularly for leaks from the fuel cap and fuel lines.
Transport and storage
•Store and transport the machine and fuel so that there is no risk of any leakage or fumes coming into contact with sparks or open flames, for example, from electrical machinery, electric motors, electrical relays/ switches or boilers.
•When storing and transporting fuel always use approved containers intended for this purpose.
•When storing the machine for long periods the fuel tank must be emptied. Contact your local petrol station to find out where to dispose of excess fuel.
•Ensure the machine is cleaned and that a complete service is carried out before long-term storage.
•The transport guard must always be fitted to the cutting attachment when the machine is being transported or in storage.
•Secure the machine during transport to prevent loss of fuel, damage or injury.
•In order to prevent unintentional starting of the engine, the spark plug cap must always be removed during long-term storage, if the machine is not under close supervision and when performing all service measures.
WARNING!Take care when handling fuel. ! Bear in mind the risk of fire, explosion
and inhaling fumes.
Fuel
CAUTION! The machine is equipped with a two-stroke engine and must always be run using a mixture of petrol and two-stroke oil. It is important to accurately measure the amount of oil to be mixed to ensure that the correct mixture is obtained. When mixing small amounts of fuel, even small inaccuracies can drastically affect the ratio of the mixture.
WARNING! Fuel and fuel fumes are ! highly inflammable and 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.
Petrol
CAUTION! Always use a quality petrol/oil mixture at least 90 octane (RON). If your machine is equipped with a catalytic converter (see chapter on Technical data) always use a good quality unleaded petrol/oil mixture. Leaded petrol will destroy the catalytic converter.
Use low-emission petrol, also known as alkylate petrol, if it is available.
Ethanol blended fuel, E10 may be used (max 10% ethanol blend). Using ethanol blends higher than E10 will create lean running condition which can cause engine damage.
•The lowest octane recommended is 90 (RON). If you run the engine on a lower octane grade than 90 socalled knocking can occur. This gives rise to a high engine temperature, which can result in serious engine damage.
•When working at continuous high revs a higher octane rating is recommended.
Two-stroke oil
•For best results and performance use Universal, Universal powered by McCULLOCH two-stroke engine oil, which is specially formulated for our aircooled two-stroke engines.
•Never use two-stroke oil intended for water-cooled engines, sometimes referred to as outboard oil (rated TCW).
•Never use oil intended for four-stroke engines.
•A poor oil quality and/or too high oil/fuel ratio may jeopardise function and decrease the life time of catalytic converters.

• Clean the area around the fuel cap. Contamination in the tank can cause operating problems.
• Ensure that the fuel is well mixed by shaking the container before filling the tank.
English – 15
STARTING AND STOPPING
Check before starting
•Check the blade to ensure that no cracks have formed at the bottom of the teeth or by the centre hole. The most common reason why cracks are formed is that sharp corners have been formed at the bottom of the teeth while sharpening or that the blade has been used with dull teeth. Discard a blade if cracks are found.
• Never use the machine without a guard nor with a defective guard.
• All covers must be correctly fitted and undamaged before you start the machine.
Starting and stopping
•Check that the support flange is not cracked due to fatigue or due to being tightened too much. Discard the support flange if it is cracked.
•Ensure the locking nut has not lost its captive force. The nut lock should have a locking force of at least 1.5 Nm.The tightening torque of the locking nut should be 35-50 Nm.
•Check that the blade guard is not damaged or cracked. Replace the blade guard if it is exposed to impact or 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 exposed to impact or are cracked.
WARNING! The complete clutch cover ! and shaft must be fitted before the
machine is started, otherwise the clutch can come loose and cause personal injury.
Always move the machine away from the refuelling area and source before starting. Place the machine on a flat surface. 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 15 meters.

General working instructions
IMPORTANT!
This section describes the basic safety precautions for working with brush cutters 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.
•CAUTION! Do not use the machine unless you are able to call for help in the event of an accident.
2Inspect the working area. Remove all loose objects, such as stones, broken glass, nails, steel wire, string, etc. that could be thrown out or become wrapped around the cutting attachment.
3Do 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.
4Wear harness before operation.
5Make 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.
6Keep a good balance and a firm foothold. Do not overreach. Keep proper footing and balance at all times.
7Always hold the machine with both hands. Hold the machine on the right side of your body.
8Keep all parts of your body away from the rotating cutting attachment.
9Dress properly. Do not wear loose clothing or jewellery. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts.
10Keep the cutting attachment below waist level.
11Switch off the engine before moving to another area. Fit the transport guard before carrying or transporting the equipment any distance.
12Never put the machine down with the engine running unless you have it in clear sight.
13Never use the machine if you are fatigued, while under the influence of alcohol or drugs, medication or anything that could affect your vision, alertness, coordination or judgement.
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 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
15 metres. Stop the machine immediately if anyone approaches. Never swing the machine around without first checking behind you to make sure no-one is within the safety zone.

WORKING TECHNIQUES
Basic working techniques
Always slow the engine to idle speed after each working operation. Long periods at full throttle without any load on the engine can lead to serious engine damage.
WARNING! Sometimes branches or
! grass get caught between the guard and cutting attachment. Always stop the engine before cleaning.
WARNING! Machines fitted with grass
! blades can be thrown violently to the side when the blade comes into contact with a fixed object.This is called blade thrust. A blade thrust can be violent enough to cause the machine and/or operator to be propelled in any direction, and possibly lose control of the machine.
Blade thrust can occur without warning if the machine snags, stalls or binds. Blade thrust is more likely to occur in areas where it is difficult to see the material being cut.
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, blade thrust can occur if you attempt to cut thick stems with this area of the blade.
Grass clearing using a grass blade
•Grass blades and grass knifes must not be used on woody stems.
•Grass blade is used for all kinds of high or thick grass. The more teeth the blade got the better will the cutting result be.
•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 firmly with your feet apart. Move forward after the return stroke and stand
firmly 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:
1Always work at full throttle.
2Avoid 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
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 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. CAUTION! This technique increases the wear on the cord.
20 – English
WORKING TECHNIQUES
•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 (80%) 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 difficult 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.
•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 the cord parallel to and above the area to be swept and move the tool side to side.
•When cutting and sweeping you should use full throttle to obtain the best results.

MAINTENANCE
Carburettor
Adjustment of the idle speed
Before any adjustments are made, make sure that the air
filter is clean and the air filter cover is fitted.
Adjust the idle speed using the idle adjustment screw T, if it is necessary to readjust. First turn the idle adjustment screw T clockwise until the cutting attachment starts to rotate. Then turn the screw anticlockwise until the cutting attachment stops. The idle speed is correctly adjusted when the engine will run smoothly in every position. The idle speed should also be well below the speed at which the cutting attachment starts to rotate.
Recommended idle speed: See the Technical data section.
WARNING! If the idle speed cannot be
! adjusted so that the cutting attachment stops, contact your dealer/service workshop. Do not use the machine until it has been correctly adjusted or repaired.
Muffler
CAUTION! Some mufflers are fitted with a catalytic converter. See chapter on Technical data to see whether your machine is fitted with a catalytic converter.
The muffler is designed to reduce the noise level and to direct the exhaust gases away from the operator. The exhaust gases are hot and can contain sparks, which may cause fire if directed against dry and combustible material.
22 – English
Some mufflers are equipped with a special spark arrestor mesh. If your machine has this type of muffler, you should clean the mesh at least once a month. This is best done with a wire brush. On mufflers without a catalytic converter the mesh should be cleaned weekly, or replaced if necessary. On mufflers fitted with a catalytic converter the mesh should be checked, and if necessary cleaned, monthly. If the mesh is damaged it should be replaced. If the mesh is frequently blocked, this can be a sign that the performance of the catalytic converter is impaired. Contact your dealer to inspect the muffler. A blocked mesh will cause the machine to overheat and result in damage to the cylinder and piston.
NOTE!
Rear housing shown removed for clarity only. It is not recommended to remove cover for maintenance of screen.
CAUTION! Never use a machine with a defective muffler.
WARNING! Mufflers fitted 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 fire!
Cooling system
To keep the working temperature as low as possible the machine is equipped with a cooling system.
2
1
The cooling system consists of: 1 Air intake on the starter.
2Cooling fins on the cylinder.
MAINTENANCE
Clean the cooling system with a brush annually or more often in demanding conditions. A dirty or blocked cooling system results in the machine overheating which causes damage to the piston and cylinder.
Spark plug
The spark plug condition is influenced by:
•Incorrect carburettor adjustment.
•An incorrect fuel mixture (too much or incorrect type of oil).
•A dirty air filter.
These factors cause deposits on the spark plug electrodes, which may result in operating problems and starting difficulties.
If the machine is low on power, difficult to start or runs poorly at idle speed: always check the spark plug first before taking any further action. If the spark plug is dirty, clean it and check that the electrode gap is 0.65 mm. The spark plug should be replaced after about a month in operation or earlier if necessary.
0,65
CAUTION! Always use the recommended spark plug type! Use of the wrong spark plug can damage the piston/ cylinder. Check that the spark plug is fitted with a suppressor.
Two-piece shaft
The drive shaft end in the lower shaft should be lubricated with grease every 30 hours. There is a risk that the drive shaft ends (splined coupling) on models with two-piece shafts will seize if they are not lubricated regularly.
Air filter
The air filter must be regularly cleaned to remove dust and dirt in order to avoid:
•Carburettor malfunctions
•Starting problems
•Loss of engine power
•Unnecessary wear to engine parts.
•Excessive fuel consumption.
Clean the filter every 25 hours, or more regularly if conditions are exceptionally dusty.
Cleaning the air filter
Remove the air filter cover and take out the filter. Wash it clean in warm, soapy water. Ensure that the filter is dry before refitting it.
An air filter that has been in use for a long time cannot be cleaned completely. The filter must therefore be replaced with a new one at regular intervals. A damaged air filter must always be replaced.
If the machine is used in dusty conditions the air filter should be soaked in oil. See instructions under the heading Oiling the air filter.
Oiling the air filter
Always use filter oil, art. no. 531 00 92-48. The filter oil contains a solvent to make it spread evenly through the
filter. You should therefore avoid skin contact.
Put the filter in a plastic bag and pour the filter oil over it.
Knead the plastic bag to distribute the oil. Squeeze the excess oil out of the filter inside the plastic bag and pour off the excess before fitting the filter to the machine. Never use common engine oil.This would drain through the filter quite quickly and collect in the bottom.
English – 23
MAINTENANCE
Bevel gear
The bevel gear is filled with the right quantity of grease at the factory. However, before using the machine you should check that the bevel gear is filled three-quarters full with grease. Use HUSQVARNA special grease.
The grease in the bevel gear does not normally need to be changed except if repairs are carried out.
Checking and adjusting of throttle wire
Make sure the throttle cable is tight enough without giving the product gas and cutting equipment starts rotate. The throttle cable should not be too loose so the product does not reached full throttle.
Adjust the nut on the throttle cable with the nut. Then tighten the lock nut.

INLEDNING
Bäste kund!
Tack för att du använder en McCulloch-produkt! Du är därmed en del av en historia som tog sin början för länge sedan, när McCulloch Corporation startade sin tillverkning av motorer under andra världskriget. Från och med 1949, när McCulloch lanserade den första lätta enmansmotorsågen, skulle skogsarbetet aldrig bli sig likt igen.
Utvecklingen av innovativa motorsågar skulle fortsätta genom årtiondena, och verksamheten utökades, först med motorer för flygplan och gokarts på 1950-talet, och sedan med minimotorsågar på 1960-talet. På 1970och 80-talet utökades sortimentet med trimmers och lövblåsare.
Idag bygger McCulloch som en del av Husqvarna-koncernen vidare på den tradition av kraftfulla motorer, tekniska innovationer och utmärkande design som varit vårt kännetecken i mer än ett halvsekel. Minskad bränsleförbrukning, minskade utsläpp och lägre ljudnivåer är av högsta prioritet för oss, på samma sätt som att förbättra säkerheten och användarvänligheten.
Vi hoppas att du kommer att vara nöjd med din McCulloch-produkt, som är utformad för att vara din följeslagare under en lång tid framöver. Genom att följa råden i bruksanvisningen gällande användning, service och underhåll kan produktens livslängd utökas. Om du behöver professionell hjälp med reparation eller service, kan du använda dig av vår Service Locator på www.mcculloch.com.
McCulloch arbetar ständigt med att vidareutveckla sina produkter och förbehåller sig därför rätten till ändringar beträffande bl.a. form och utseende utan föregående meddelande.
Den här bruksanvisningen kan också laddas ned från www.mcculloch.com.
