This machine produces an electromagnetic field during operation. This field may, under certain circumstances, affect active or non-active medical implants. To reduce the risk of serious injury or death, persons with medical implants should consult their doctor and the manufacturer of the medical implant before using the machine.

The exhaust gases emitted from engine contain dangerous carbon monoxide. Running an engine in an enclosed or badly ventilated area can result in death due to suffocation or carbon monoxide poisoning.

Prolonged exposure to vibrations can cause injuries and neurovascular disorders (also called "Raynaud's syndrome" or "white hand"), especially to people suffering from circulation disorders.

The symptoms can regard the hands, wrists and fingers and are shown through loss of sensitivity, torpor, itching, pain and discolouring of or structural changes to the skin. These effects can be worsened by low ambient temperatures and/or by gripping the handgrips excessively tightly. If the symptoms occur, the length of time the machine is used must be reduced and a doctor consulted.

PERSONAL PROTECTIVE EQUIPMENT

IMPORTANT!

• Approved protective equipment must be worn every time the machine is used. Personal protective equipment cannot eliminate the risk of injury but it will reduce the degree of injury if an accident does happen. Ask the retailer for help in choosing the right equipment.
• Pay attention to warning signals or warning calls when ear protection is being used. Always remove your hearing protection as soon as the engine stops.
• Wear hearing protection which provides sufficient noise reduction. Always wear approved eye protection.
• Gloves should be worn when required.
• Wear safety shoes with steel toes and non-slip soles.
• 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. Tie up hair so it is above shoulder level.

BASIC SAFETY RULES

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

- 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 means increased risk.

- 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.

- Keep a good balance and a firm foothold.

• Always hold the machine with both hands. Hold the machine on the right side of your body.

• Keep the trimmer head below waist level.
• Switch off the engine before moving to another area.
• Never put the machine down with the engine running unless you have it in clear sight.
• It is not permitted for the operator of the machine or anyone else to attempt to remove the cut material while the engine is running or the trimmer head is rotating, as this can result in serious injury.
• Stop the engine and trimmer head before you remove material that has wound around the machine's shaft as otherwise there is a risk of injury.
• The gear drive can become hot during use and remain so for a while. You could get burnt if you touch it.
• Watch out for objects being ejected. Always wear approved eye protection. Never lean over the trimmer guard. Stones, rubbish, etc. can be thrown up towards the eyes and cause blindness or serious injury.
• Keep unauthorised persons at a distance. Children, animals, onlookers and helpers should be kept outside the safety zone of 15 m. 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.

THE MACHINE'S SAFETY EQUIPMENT

WARNING! Never use a machine with safety equipment that is not working. The machine's safety equipment must be checked and maintained according to the instructions in this section. If your machine fails any of these checks contact your service agent to get it repaired.

Vibration damping system

• Your machine is equipped with a vibration damping system that is designed to minimize vibration and make operation easier.
• Vibrations increase when using an incorrectly wound cord or a blunt or faulty blade (wrong type or incorrectly sharpened).
• The machine's vibration damping system reduces the transfer of vibration between the engine unit and the machine's handle.
• Check regularly that the vibration damping devices have not become cracked or damaged.
• Check that the vibration damping element is undamaged and securely attached.

The harness quick-release

There is an easily accessible quick-release alongside the suspension ring. This is a safety device to be used if the engine should begin to catch fire or in other situations where the operator needs to free themselves from the machine.

Trimmer guard

- The trimmer guard is intended to prevent loose objects being thrown towards the operator. The guard also protects the operator from accidental contact with the trimmer head.

• Check that the guard is undamaged and not cracked. Replace the guard if it is damaged.
  • Always use the recommended guard for the trimmer head you are using.
• Never use a trimmer head without an approved guard. 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 operator.
• Never use a machine that has a faulty muffler.
• Regularly check that the muffler is securely attached.
• The inside of the muffler contain chemicals that may be carcinogenic. Avoid contact with these elements in the event of a damaged muffler.
• Remember that the muffler and exhaust fumes from the engine are hot and may contain sparks which can cause a fire. Never start the machine indoors or near combustible material!

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 recommended cords.
• Smaller machines generally require small trimmer heads and vice versa. This is due to the fact that when clearing, the engine has to eject the line radially from the trimmer head, and must be able to handle the resistance from 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 line to the correct length.

IMPORTANT!

• Only use a trimmer reel with the recommended guard! Refer to the instructions for the cutting attachment to check the correct way to load the cord and the correct cord diameter.
• Always stop the engine before carrying out any work on the machine. The trimmer head continues to rotate even after the throttle has been released. Check that the trimmer head has completely stopped and the spark plug lead has been disconnected from the spark plug before carrying out any work on the machine. Using a faulty accessory or faulty trimmer head increases the risk of blade thrust.

HANDLING FUEL

Fuel safety

Never start the machine in the following situations:

• If fuel has spilt onto the machine. Wipe off the spillage and allow remaining fuel to evaporate.
• If fuel has spilt onto your body or clothes. Change clothes and wash the body parts which came into contact with the fuel using soap and water.
• If 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 naked 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 a local petrol station to find out how excess fuel should be disposed of.
• Ensure the machine has been cleaned and that a full service has been carried out before the machine is stored for a long period.
  – Secure the machine during transport.
• To prevent the engine accidentally starting, the spark plug cap must always be removed during long-term storage if the machine is not under constant supervision. This also applies to all service measures.
  — Take care when handling fuel. Bear in mind the risk of fire, explosion and inhaling fumes.

INSTALLATION

Assembling the front handle

Fit the front handle (B) and clamp (C) onto the tube (A) using two sets of washers (D), spring washers (E) and screws (F).

Fitting the pole

1. Align the hole (A1) on the front tube (A) and the locking pin (B).
2. Then pull out the locking pin while inserting the front tube all the way into the connector (D).
3. Release the locking pin. It will spring back to its original position and come out through the hole on the front tube.
4. Check that the front tube cannot be rotated once the locking pin is in the correct position.
5. Turn the locking knob (C) to tighten the front tube securely.

Fitting trimmer heads

If the trimmer head is incorrectly fitted this could lead to serious injury and/or death. Never use a trimmer head without an approved guard. If a faulty or broken guard is fitted, this could lead to serious injury.

Fitting the trimmer guard

1. Use a screw (E) to secure the bracket (F) on the drive shaft tube (B).
2. Hook the guard (A) onto the shaft bracket, and then secure with the clamp (C) and two screws (D).

Fitting trimmer heads

1. Use a wrench (B) for the locking nut (A).
2. Screw on the trimmer head (C) in the opposite direction to the direction of rotation.
3. Follow the instructions in reverse order to dismantle.

Adjusting the brush cutter's working height

1. Adjust the shoulder strap so that the cutting attachment is parallel to the ground.
2. Let the cutting attachment rest lightly on the ground.
3. Adjust the position of the suspension ring to balance the brush cutter correctly. Tighten the side straps so the weight is evenly distributed across both shoulders.

NB

• When the brush cutter is in use it must always be fastened securely to the harness. If it is not, the brush cutter cannot be controlled in a safe manner which could lead to the operator or other people being injured.
• Never use a harness with a defective quick release.
• Use the quick release if the engine for instance catches fire or in other emergency situations where the operator needs to free themselves from the machine or harness.
• A well-adjusted harness and machine makes work much easier. Adjust the harness for the best working position.

OPERATION

Fuel

The machine is equipped with a 2-stroke engine and must always be operated with a mixture of petrol and 2-stroke oil. For best results and performance use 2-stroke engine oil which is specially formulated for air-cooled 2-stroke engines. Never use 2-stroke oil intended for water-cooled engines or oil intended for 4-stroke engines. A low quality oil and/or too much oil in relation to petrol can jeopardise function and reduce the engine's lifespan. It is important to accurately measure the amount of oil to be mixed to ensure that the correct mixture is obtained.

Mixing ratio: 1:40 (2.5%).

Petrol 2-stroke oil 1:40 (2.5%)
1 litre 25 ml
5 litres 125 ml
10 litres 250 ml

NB

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.

Mixing

1. Always start by filling half the amount of the petrol to be used.
2. Then add the entire amount of oil. Mix (shake) the fuel mixture.
3. Add the remaining amount of petrol.
4. Mix (shake) the fuel mixture thoroughly before filling the machine's fuel tank.

Always mix the petrol and oil in a clean container intended for fuel. Do not mix more than one month's supply of fuel at a time. If the machine will not be used for some time, the fuel tank should be emptied and cleaned.

Fuelling

Taking the following precautions, will lessen the risk of fire:

• Do not smoke or place hot objects near the fuel.
  – Always shut off the engine before refuelling.
• Always stop the engine and let it cool for a few minutes before refuelling.
• When refuelling, open the fuel cap slowly so that any excess pressure is released gently.
  – Tighten the fuel cap carefully after refuelling.
• Always move the machine away from the refuelling area before starting.
• Always use a fuel container with an anti-spill valve.
• 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.

USE

Check before starting

• Never use the machine without a guard nor with a defective guard.
• All guards and covers must be correctly fitted and undamaged before you start the machine.
• 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.
• Check that the mounting 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 has not become damaged or cracked. Replace the blade guard if it is exposed to impact or is cracked.

• Check that the trimmer head and trimmer guard have not become damaged or cracked. Replace the trimmer head or trimmer guard if they have been exposed to impact or are cracked.

• 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 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 metres.

Throttle trigger lockout

The throttle lockout is designed to prevent accidental operation of the throttle control. When you press the lock-out (A) (i.e. when you grasp the handle) it releases the throttle trigger (B). When you release the handle the throttle control and the throttle lockout both move back to their original positions. The movement is controlled by two independent return springs. 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 lockout is released. Press the throttle lockout and make sure it returns to its original position when released.

Check that the throttle control and throttle lockout move freely and that the return springs work properly. Start the machine and apply full throttle. Release the throttle and check that the blade stops and remains still. If the cutting attachment rotates with the throttle in the idle position then the carburettor idle setting must be checked.

Cold start

A "cold" start of the engine means starting it after at least 5 minutes from when it was switched off or after refuelling.

1. Press down the "I" side of the engine switch.
2. Press the primer bulb repeatedly until fuel begins to fill the bulb. It does not have to be completely filled.
3. Close the choke.
4. When pressing throttle trigger lock-out and throttle trigger, press the throttle lock button simultaneously, and then release throttle trigger and throttle trigger lock-out.

1. Hold the machine against the ground using your left hand. NB Do not use your foot. Grip the starter handle, pull out the starter cord slowly with your right hand until it begins to tighten and then pull the cord strongly. Never twist the starter cord around your hand. Continue pulling the starter cord until the engine starts.
2. Set the choke to the open position
3. Repeat pulling the cord until engine firing occur. When the engine starts, allow the engine to warm up with the throttle pulled slightly. Then, pressing throttle trigger to release the throttle lock.

NB The throttle lock will automatically release by pressing the throttle trigger again. If you manually turn the choke knob from choke position to run position before releasing the throttle lock, the cutting attachment will start to rotate immediately when the engine is started.

IMPORTANT!

• Do not pull the starter cord all the way out and do not let go of the starter handle when the cord is fully extended. This can damage the machine
• Avoid letting any part of your body enter the marked area. Body contact with this area could result in burns or electrical shock if the spark plug cap is damaged. Always use gloves. A machine which has a damaged spark plug cap must not be used.
• If the starter cord is pulled repeatedly when the choke is on, the engine could be flooded making it difficult to start.
• If the engine does flood, the warm start procedure should be repeated several times until the excess fuel has been removed.

Warm start

Warm start the engine immediately after it has stopped by following steps 1, 2, 4 and 7 according to the procedure above and remember to not press the primer button more than 2 to 3 times.

Switching off

Switch the engine off by setting the engine switch to the "0" position.

GENERAL WORKING INSTRUCTIONS

IMPORTANT! In this section the basic safety measures for working with brush cutters and trimmers are described. If you encounter a situation where you are uncertain how to proceed you should ask an expert. Contact the retailer or service centre if the equipment is not working as intended. You must understand the difference between grass clearing and grass trimming before use.

Basic working techniques

Always allow the engine to slow down to idle speed when not cutting or trimming. Long periods at full throttle without any load on the engine can lead to serious engine damage. Sometimes branches or grass get caught between the guard and cutting attachment. Always stop the engine before cleaning.

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

Hold the trimmer head just above the ground at an angle. Let the end of the cord strike the ground around trees, posts, statues and the like. NB 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 difficult to reach using a normal lawn mower. Keep the line 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.

Clearing up

The rotating fan effect of the line 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 to and fro. When cutting and sweeping you should use full throttle to obtain the best results.

MAINTENANCE

Adjusting idle speed

Check that the air filter is clean. When the idle speed is correct, the cutting attachment should not rotate. If adjustment is required, the idle adjustment screw T must be turned clockwise until the blade begins to rotate. Open (turn anticlockwise) the screw until the cutting attachment stops. The idle speed is correctly set when the engine runs smoothly in all positions, and there is a clear margin to the speed at which the trimmer head starts to rotate. If the idle speed cannot be adjusted so that the trimmer head stops, contact your dealer/service workshop. Do not use the machine until it has been correctly adjusted. If you need to adjust the "L" and/or "H" mixture screw contact your service centre for assistance.

Cleaning the air filter

1. Remove the air filter guard and then the filter.
2. Wash it with warm water and washing-up liquid.
3. Check that the filter has dried out fully before refitting.

Technical illustration of a mechanical assembly with a clamped component and two separate parts (no text or symbols)

The air filter must be regularly cleaned to remove dust and dirt in order to avoid:

– Carburettor malfunction
- 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. 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.

Fuel Filter

When the fuel supply to the engine is interrupted, the fuel cap and fuel filter must be checked to ensure they are not blocked.

Spark plug

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 0.6–0.7 mm. The spark plug should be replaced after about a month in operation or earlier if necessary. Always use the recommended spark plug type! Using the wrong type of spark plug could damage the piston/cylinder. Check that the spark plug is fitted with a suppressor.

The condition of the spark plug is affected by the following factors:

• Incorrect carburettor adjustment.
• An incorrect fuel mixture (too much or incorrect type of oil).
• A dirty air filter.
