The machine‘s safety equipment

IMPORTANT INFORMATION

This section describes the machine‘s safety equipment, its

function and how checks and maintenance are carried out to

ensure that it operates correctly. (See the chapter “What is

what“ to locate where this equipment is positioned on your

machine.)

•

Incorrect or careless use of a clearing saw,

brushcutter or trimmer can turn it into a dangerous

tool that can cause serious or even fatal injury to

the operator or others. It is extremely important

that you read and understand the content of this

manual.

WARNING!

Never use a machine with defective safety

equipment. Follow the control,

maintenance and service instructions

described in this section.

•

When using a clearing saw, brushcutter or trimmer,

protective equipment approved by the appropriate

authorities must be used. Personal protective

equipment does not eliminate the risk of

accidents, however, it can reduce the effects of an

injury in the event of an accident. Ask your dealer

for help when choosing protective equipment.

SAFETY INSTRUCTIONS

2. Stop switch

4. Anti-vibration

system

The stop switch should be

used to stop the engine.

Your machine is equipped

with an anti-vibration system

that has been designed to

give as vibration-free and

comfortable usage as

possible.

The use of incorrectly

wound cord or blunt,

incorrect cutting equipment

(incorrect type or incorrectly

sharpened, see section “Filing

the blade”) increases the level

of vibration.

The machine’s vibration

damping system reduces the

transfer of vibrations

between the engine unit/

cutting equipment and the

machine’s handle unit.

WARNING!

Over exposure to vibrations can result in

blood-vessel or nerve injury to persons

suffering with blood circulation problems.

Seek medical attention if you experience

physical symptoms that can be related to

over exposure to vibrations. Examples of

such symptoms are “numbness“, lack of

feeling, “tickling“, “pricking“, “pain“, lack of

or a reduction in normal strength, changes

in the colour of the skin or its surfaces.

These symptoms normally appear in the

fingers, hands or wrists.

3. Cutting

attachment guard

This guard is intended to

prevent objects from being

thrown towards the operator

and to protect the operator

from unintentionel contact

with the cutting attachment.

5. Quick-release

There is an easily accessible,

quick-release catch fitted to

the chest as a safety

precaution in the event of a

fire in the engine or for any

other situation that requires

you to free yourself from the

machine and harness. See the

section “Adjusting the harness

and clearing saw“.

WARNING!

Do not attach any blade to the unit without

proper installation of all required parts.

Failure to use the proper parts can cause

the blade to fly off and seriously injure the

operator and/or bystanders.

Under no circumstances may the cutting

equipment be used without an approved

guard fitted. See the chapter “Technical

data”. If the wrong guard or a defective

guard is fitted this can cause serious

personal injury.

SAFETY INSTRUCTIONS

Sharpening the

grass blade

Cutting equipment

IMPORTANT INFORMATION

• See the cutting

equipment’s packaging for

correct filing instructions.

The section describes how through correct mainte-

nance 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.

• The blades are sharpened

using a single cut flat file.

•

Only use the cutting and guard equipment we

recommend! See chapter “Technical data“.

• Sharpen all edges equally

to maintain the balance of

the blade.

•

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 teeht well and correctly

sharpened! Follow our recommendations. Also

refer to the instructions on the blade packaging.

Trimmer head

Maintain the correct setting. Follow our instruc-

tions and use the recommended filing gauge.

• 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! See chapter

“Technical data“.

WARNING!

Incorrect cutting equipment or an

incorrectly sharpened blade increases

the risk of kickback.

Sharpening the

clearing blade

• See the cutting

equipment’s packaging for

correct filing instructions.

• 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.

• A correctly sharpened

blade is a prerequisite for

working efficiently and to

avoid unnecessary wear to

the blade and clearing saw.

• Make sure that the blade is

well supported when you

use the file. Use a 5,5 mm

round file with a file

holder.

• 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.

• The sharpening angle is

15°. Every other tooth is

sharpened to the right and

the intermediate tooth to

the left. When the blade

has been heavily pitted by

stones the upper side of

the teeth can, in

exceptional cases, need to

be dressed using a flat file.

In such cases this takes

place before sharpening

with the round file.

• 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.

WARNING!

Always stop the engine before starting

work on any part of the cutting equipment.

Dressing the top side must

be carried out equally for

all teeth.

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.

• Adjust the setting. This

should be 1 mm.

SAFETY INSTRUCTIONS

Adjusting the harness and clearing saw

Basic clearing techniques

WARNING!

• Always drop to idling speed after each working operation.

Longer periods running at full throttle without loading the

engine (that is without resistance, which the engine feels

from the cutting equipment when trimming) can lead to

serious engine damage.

When working with the clearing saw it

should always be hooked in the harness. If

this is not done, you cannot control the

clearing saw safely and this can result in

injury to yourself or someone else. Never

use a harness with a defective quick

release catch.

Designations

Quick release

On the front is an easily

accessible, quick release

catch. Use this if the engine

should catch fire or in any

other emergency situation

when you quickly need to

take off the harness and

machine.

• Forestry clearing is a

general term for cutting

small trees where each

stem is cut individually.

A saw blade is used.

• Brush cutting is a general

term for clearing grass.

Grass blades are used for

this purpose.

Even load on the

shoulders

A well-adjusted harness and

clearing saw significantly

facilitates working. Adjust

the harness for the best

working position. Tension

the side straps so that the

weight is evenly distributed

across the shoulders.

• Grass trimming is a

general term for light

clearing, e.g. around

edges or around trees. A

trimmer head or plastic

blade is used.

Correct height

1) Forestry clearing

WARNING!

Sometimes branches, grass or wood can

get caught between the guard and cutting

equipment. Always stop the engine when

cleaning.

Adjust the carrier strap so

that the suspension hook

comes approximately 10

cm under the hip. The

blade should be angled

forward a little.

2)Grass clearing

The suspension hook

should hang

approximately 20 cm

under the hip so that the

blade is parallel to the

ground.

Correct balance

1)Forestry clearing

Move the suspension eye

forwards or backwards. If

the blade is balanced a 10-

20 cm above the ground it

is easier to avoid stones.

2)Grass clearing

Let the blade balance at a

comfortable clearing

height, i.e. close to the

ground.

SAFETY INSTRUCTIONS

Trimming

Grass clearing

using the trimmer

head and plastic

knifes

• The trimmer is ideal to

cut 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.

• Hold the trimmer head

just above the ground at

an angle. It is the end of

the cord that carries out

the work. Let the cord

work at its own pace.

Do not press the cord

into the area to be cut.

• Do not allow the

trimmer head to

• 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.

constantly come into

contact with the ground

during normal cutting

procedures. Constant

contact can cause damage

and wear to the trimmer

head.

• Reduce the risk of

damaging plants by

shortening the cord to

10-12 cm and reducing

the engine speed.

Sweeping

• The rotating cord‘s

fanning effect can be

used for quick and easy

cleaning. Hold the cord

parallel to and above the

area to be swept and

move the trimmer from

side to side.

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. NOTE! This

technique increases the

wear on the cord.

• When cutting and

sweeping you should use

full throttle to obtain the

best results.

WARNING!

Beware of thrown objects. Always wear eye

• 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.

protection. Never lean over the guard.

Stones, rubbish etc. can be thrown up into

the eyes resulting in blindness or other

serious injury.

Keep unauthorised persons at a distance.

Children, animals, onlookers and helpers

should be outside the safety zone of 15

meters (50 feet). Stop the machine

immediately if anyone approaches.

• 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.

FUEL HANDLING

Mixture

Fuel mixture

• Always mix gasoline and oil in a clean container intended for

NOTE!

fuel.

The machine is fitted with a two-stroke engine and must

always be run on a mixture of gasoline 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.

• Always start by filling half the quantity of gasoline required.

Then add the entire oil quantity. Mix (shake) the fuel

mixture. Fill the remaining quantity of gasoline.

• Mix (shake) the fuel mixture carefully before filling in the

machine‘s fuel tank.

WARNING!

Always provide good ventilation when

handling fuel.

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

• If the machine is not used for a long period of time, the fuel

tank should be emptied and cleaned.

Gasoline

• This engine is certified to operate on unleaded gasoline.

NOTE!

Always use an oil-mixed

quality gasoline (at least 87

octane). If your machine is

equipped with a catalytic

converter, (see “technical

data”) an unleaded, oil

mixed quality gasoline

should always be used. A

leaded gasoline will destroy

the catalytic converter.

WARNING!

The catalytic converter muffler gets very hot

during and after use.This also applies

during idling. Be aware of the fire hazard,

especially when handling the saw near

flammable substances or vapours.

Fuelling

WARNING!

The following precautions reduce the risk

of fire:

• This engine is certified to

operate on unleaded

gasoline.

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.

• The lowest recommended

octane rating is 87. If you

run the engine on lower

octane rating than 87 so-

called “knocking“ can

occur. This leads to an

increased engine

temperature, which can

result in a serious engine

breakdown.

• Clean around the fuel cap.

Contamination in the tank

can disrupt operations.

• When working at

continuous high revs a

higher octane rating is

recommended.

• Ensure that the fuel is well

mixed by shaking the

container before filling the

tank.

• 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.

returning it to its original

position.

Discard a blade if cracks

are found.

• 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

torque of the locking nut

should be 35-50 Nm.

• Check that the guard is not

damaged or cracked.

Replace the guard if it is

exposed to impact or is

Correctly adjusted carburetor

A correctly adjusted carburetor means that the machine

accelerates without hesitation and the machine 4-cycles a

little at max speed. Furthermore, the cutting attachment

must not rotate/move at idling. A too lean adjusted low

speed needle L may cause starting difficulties and bad

acceleration.

A too lean adjusted high speed needle H gives lower power =

less capacity, bad acceleration and/or damage to the engine.

A too rich adjustment of the two speed needles L and H gives

acceleration problems or too low working speed.

Then turn, counter-

clockwise until the cutting

attachment stops. A correctly

adjusted idle speed setting

occurs when the engine runs

smoothly in every position.

It should also be good

The high speed needle

affects the machine’s power,

speed, temperature and fuel

consumption. A too lean

adjustment on the high

needle. Therefore dismantle

the cutting equipment, nut,

support flange and disc drive

before adjusting the high speed needle. The high speed needle

is adjusted correctly when the machine ‘splatters’ a little . If the

machine smokes heavily at the same time as it ‘splatters’ heavily

the adjustment is too rich.

NOTE! For optimum setting of the carburetor, contact a

qualified servicing dealer who has a revolution counter at his

disposal.

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 mate-

rial. Some mufflers are

arrest 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

NOTE!

Never use a machine with a

defective muffler.

WARNING!

Mufflers fitted with catalytic converters

become extremely hot during use and

after stopping.This also applies at idling

speeds. Contact can result in burns to

the skin. Be observant to the risk of fire!

Oiling the air filter

Air filter

Always use HUSQVARNA

filter oil, order no. 503 47

73-01. 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 the 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 on the

machine. Never use common

engine oil. This would drain

through the filter quite

The air filter should be

cleaned regularly removing

dust and dirt to avoid:

• carburettor malfunction

• starting problems

• reduced engine power

• unnecessary wear to

engine parts

• abnormal fuel

consumption

Clean the filter after every

quickly and collect in the

bottom.

Cleaning the air filter

240R, 245R/RX

An air filter used for a long

period of time can never be

cleaned completely.

Therefore it is necessary to

replace the filter from time

to time with a new filter. A

damaged air filter must

always be replaced.

Remove the air filter cover

and take out the air filter.

Wash it clean in warm soapy

water. Ensure that the filter

is dry before refitting.

If the machine is used in

dusty conditions the air

filter should be soaked in oil,

see the section on “Oiling

the air filter“.

MAINTENANCE

Angle gear

Filing the grass blade

The angle gear is filled with a

sufficient quantity of grease

at the factory. However,

before using the machine you

should check that the angle

gear is filled to 3/4 with

grease. Use HUSQVARNA

special grease.

WARNING!

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.

Normally, the grease does not

need to be changed except

when the angle gear is

repaired.

• See the cutting equipment’s

packaging for correct filing

instructions.

• The blades are sharpened

using a single cut flat file.

• Sharpen all edges equally to

maintain the balance of the

blade.

Spark plug

The condition of the spark

plug is affected by:

• An incorrect carburettor

setting.

• An incorrect fuel mixture

(too much or faulty oil).

• A dirty air filter.

0,5 mm

WARNING!

Always discard a blade that is bent,

twisted, cracked, shattered or damaged in

any other way. Never attempt to straighten

a twisted blade for use again. Only use

original blades of the prescribed type.

These factors cause deposits

on the spark plug electrode

that may result in

malfunction or starting

difficulties.

If the machine is low on power, difficult to start or runs

poorly while idling always check the spark plug first.

If the spark plug is dirty, clean it and at the same time check

that the electrode gap is 0.5 mm. The spark plug should be

changed after about one month of operation or earlier if

necessary.

NOTE! Always use the recommended type of spark plug. An

incorrect spark plug can damage the cylinder/piston.

MAINTENANCE

NOTE: Use only HUSQVARNA replacement parts. Use of

Sharpening the clearing blade

other brands of replacement parts can cause damage to your

unit or injury to the operator or others. Your warranty does

not cover damage or liability caused by the use of accessories

and/or attachments not specifically recommended by

HUSQVARNA.

WARNING!

Incorrect cutting equipment or an

incorrectly sharpened blade increases

the risk of kickback.

Maintenance schedule

Below you will find some general maintenance instructions.

• See the cutting

equipment’s packaging for

correct filing instructions.

Daily maintenance

• Check throttle trigger and throttle trigger lockout function.

• Check stop switch function.

• Check that blade/trimmer head does not rotate at idling.

• Clean the exterior of the machine.

• Check that the harness is undamaged.

• Check the blade guard for damage or cracks.

• Change the guard in case of impacts or cracks.

• Check that the blade is properly centred, sharp, and without

cracks.

• Make sure that the blade is

well supported when you

use the file. Use a 5.5 mm

round file with a file

holder.

• The sharpening angle is

15°. Every other tooth is

sharpened to the right and

the intermediate tooth to

the left. When the blade

has been heavily pitted by

stones the upper side of the

teeth can, in exceptional

cases, need to be dressed

using a flat file. In such

cases this takes place before

sharpening with the round

file. Dressing the top side

must be carried out equally

for all teeth.

• Check the trimmer head for cracks and chips or damage.

Replace if necessary.

• A non-balanced blade/trimmer head induces heavy

vibrations that may damage the machine.

• Check that the blade nut is sufficiently tightened.

• Make sure that the blade transport guard is undamaged and

that it can be securely fitted.

• Check that nuts and screws are sufficiently tightened.

Weekly maintenance

• Check the starter, especially cord and return spring.

• Clean the carburetor area.

• Clean the exterior of the spark plug.

• Remove it and check the electrode gap.

• Adjust it to 0,5 mm (.020"), or change the spark plug.

• Clean the cooling fins on the cylinder and check that the air

intake at the starter is not clogged.

• Adjust the setting. This

should be 1 mm.

• Check that the angle gear is filled with grease up to 3/4. Use

special grease.

• Clean the air filter.

• Clean or replace the muffler’s spark arrest screen (not on

mufflers with a catalytic converter).

Monthly maintenance

• Clean the fuel tank.

• Clean the exterior of the carburetor and the space around it.

• Clean the fan and the space around it.

• Check fuel hose for cracks or other damage. Change if

necessary.

• Change fuel filter in fuel tank.

• Check clutch, clutch spring and clutch drum for wear.

Change if necessary.

• Check electrical wires and connections.

• Change the spark plug.

• Change the airfilter.

• Check and clean the muffler’s spark arrest screen if necessary

(only mufflers with a catalytic converter).
