1. Throttle trigger lock

The throttle trigger lock is designed to prevent the throttle from accidentally being engaged. When the trigger lock (

is pressed into the handle (= when you hold the handle) the throttle (B) is released. When the grip on the handle is

released the throttle and the throttle trigger lock return to their original positions. This takes place via two indepen-

dent return spring systems. This means that the throttle is automatically locked in its "idling" position.

2. Stop switch

The stop switch should be used to stop the engine.

3.Debris shield

This debris shield is intended to prevent objects from being thrown

towards the operator and to protect the operator from unintentionel contact with the cutting attachment.

WARNING!

Under no circumstances may the cutting equipment be used without an approved debris shield fitted.

CONTROL AND SERVICE OF THE MACHINE’S SAFETY EQUIPMENT

1. Throttle trigger lock

• Check that the throttle is locked in the "idling position" when the throttle trigger lock is in its original position.

• Press in the throttle trigger lock and make sure it returns to its original position when released.

• Ensure that the throttle and throttle trigger lock move easily and that their return spring systems function.

• See section "Start". Start the machine and apply full throttle. Release the throttle and check that the cutting equip-

ment stops and remains at a standstill. If the cutting equipment rotates with the throttle in the idling position then the

carburetor's idling setting must be checked.

• 2. Stop switch

• Start the engine and make sure that the engine stops when the stop switch is moved to the stop

3. Debris shield

• Check that the shield is undamaged and not cracked.

• Replace the shield if it has been exposed to impact or is cracked.

• Always use the prescribed blade and shield combination.

• 4. Blade and Trimmer head

• 1) Grass blades are intended for brush cutting.

• 2) The trimmer head is intended for trimming grass.

• 5. Locking nut

• A locking nut is used to secure some types of cutting equipment on the output shaft

6. Muffler

The muffler is designed to give the lowest possible noise level and to direct

the engine's exhaust fumes away from the operator. .

In countries that have a warm and dry climate the risk of fire is obvious.

We have therefore fitted certain mufflers with a spark arrestor screen. Make

sure that your muffler is fitted with this kind of screen.

It is extremely important that the instructions for checking, maintaining

and servicing the muffler are followed.

CUTTING EQUIPMENT

IMPORTANT INFORMATION

The section describes how through correct maintenance and through using the right type of cutting equipment you

can reduce the machine's tendency to kickback, obtain maximum clearing capacity and increase the service life of

the cutting equipment.

• Only use the cutting and guard equipment we recommend!

• Refer to the instructions for the cutting equipment for the correct winding of cord and for the selection of the right

cord diameter.

• Keep the blade's teeth well and correctly sharpened! Follow our recommendations. Also refer to the instructions

on the blade packaging.

WARNING!

Incorrect cutting equipment or an incorrectly sharpened blade increases the risk of kickback.

Filing the blade

The blades are sharpened using a single cut flat file.

Sharpen all edges equally to maintain the balance of the blade.

Always stop the engine before starting work on any part of the cutting equipment. This continues to rotate even after

the throttle has been released. Ensure that the cutting equipment has stopped completely and remove the cable

from the spark plug before you start to work on it.

Trimmer head

Only use a trimmer head and trimmer cord that is recommended.

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 cutting equipment we recommend!

Generally smaller machines require a small trimmer head and vice versa.

This is because when clearing using a cord the engine must throw out the

cord radially from the trimmer head and also meet 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 the knife positioned 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 few days.

This will make the line tougher and it will keep longer.

IMPORTANT INFORMATION

Always ensure the trimmer cord is wound tightly and evenly around the drum, otherwise harmful vibrations will occur.

NOTE!

The machine is fitted with a two-stroke engine and must always be run on a mixture of petrol and two-stroke oil. It

is important to measure the quantity of oil accurately, to ensure the correct mixture ratio. Small discrepancies in the

amount of oil have a great bearing on the proportions of the fuel mixture when mixing small amounts of fuel.

WARNING!

Always provide good ventilation when handling fuel.

Petrol

NOTE!

• Always use an oil-mixed quality petrol (at least 90 octane).

• recommended octane rating is 90. If you run the engine on a petrol with a lower octane rating than 90 so-called

"knocking" can occur. This leads to an increased engine temperature, which can result in a serious engine break-

down.

• When working at continuous high revs a higher octane rating is recommended.

www.daewoopower.bg

Two-stroke oil

• For the best results use high level two-stroke oil. Mixing ratio 1:25 (4%).

• Never use oil intended of four-stroke engines.

Mixture

• Always mix petrol and oil in a clean container intended for petrol.

• Always start by filling half the quantity of petrol required. Then add the entire oil quantity. Mix (shake) the fuel mixtu-

re. Fill the remaining quantity of petrol.

• Mix (shake) the fuel mixture carefully before filling in the machine's fuel tank.

• Do not mix more than max. one month's supply of fuel.

• If the brush cutter is not used for a long period of time, the fuel tank should be emptied and cleaned.

Fuelling

WARNING!

The following precautions reduce the risk of fire:

Do not smoke or place any sources of heat in the vicinity of the fuel. Never refuel when the engine is running. Always

stop the engine and let it cool for a few minutes before refuelling. Open the fuel cap slowly when fuelling so that any

over pressure is released slowly. Tighten the fuel cap carefully after refuelling. Always move the machine from the

fuelling place before starting.

Clean around the fuel cap. Contamination i the tank can disr operations.

Ensure that the fuel is well mixed by shaking the container before filling the tank.

who has a revolution counter at his disposal, to adjust your carburetor for optimum operating conditions.

WARNING!

The complete clutch cover with shaft must be fitted before the machine is started, otherwise the clutch can become

loose and cause personal injury.

Operation

• The carburetor governs the engine's speed via the throttle. Air/fuel is mixed in the carburetor. The air/fuel mixture

is adjustable. To take advantage of the engine's optimal output the adjustment must be correct.

• The setting of the carburetor means that the engine is adapted to local conditions, for example, the climate, altitu-

de, petrol and the type of 2-stroke oil.

Idle speed adjustment

Check that the air filter is clean. When the idle speed is correct, the trimmer head will not rotate. If adjustment is

required, close (clockwise) the T-screw, with the engine running, until the trimmer head starts to rotate (3 400 rpm).

Open (counterclockwise) the screw until the trimmer head stops. You have reached the correct idle speed (about

2500 rpm) when the engine runs smoothly in all positions well below the rpm when the trimmer head starts to rotate.

Note: The carburetor adjustment should be carried by qualified specialists

WARNING!

Contact your servicing dealer, if the idle speed setting cannot be adjusted so that the cutting attachment stops. Do

not use the machine until i t has been properly adjusted or repaired.

NOTE! The machine should only be used for short periods at its highest speed.

Muffler

The muffler is designed to dampen the noise level and to direct the exhaust fumes away from the user. The exhaust

fumes are hot and can contain sparks, which can result in fire if the exhaust fumes are directed towards a dry and

inflammable material. Some mufflers are equipped with a special spark arrestor screen. If your machine is fitted with

this type of screen it should be cleaned regularly. This is done using a wire brush. On mufflers without a catalytic

converter the screen should be cleaned weekly, or replaced if necessary. On mufflers fitted with a catalytic converter

the screen should be checked and cleaned monthly. If the screen is damaged it should be replaced.

If the screen is frequently blocked, this can be a sign that the function of the catalytic converter is impaired. Contact

your dealer to inspect the muffler. A blocked screen will cause the engine to overheat resulting in damage to the

cylinder and piston. Also see under "Maintenance".

NOTE! Never use a machine with a defective muffler.

Cooling system

To maintain as low an operating temperature as possible the engine is equipped with a cooling

system. The cooling system consists of:

1. An air intake on the starter unit.

2. Cooling fins on the flywheel.

3. Cylinder cover (leads cold air onto the cylinder).

Clean the cooling system using a brush at least once a week, in difficult conditions more often.

A dirty or blocked cooling system leads to the engine overheating resulting in damage to the cylinder and piston.

Air lter

The air filter should be cleaned regularly removing dust and dirt to avoid:

• carburetor malfunction

• starting problems

• reduced engine power

• unnecessary wear to engine parts

• abnormal fuel consumption

Clean the filter after every 25 hours or more regularly if operating conditions are exceptionally dusty.
