INTRODUCTION

Dear customer!

Congratulations on your choice to buy a Husqvarna product! Husqvarna is based on a tradition that dates back to 1689,

when the Swedish King Karl XI ordered the construction of a factory on the banks of the Huskvarna River, for production

of muskets. The location was logical, since water power was harnessed from the Huskvarna River to create the water-

powered plant. During over 300 years of continuous operation, the Husqvarna factory has produced a lot of different

products, from wood stoves to modern kitchen appliances, sewing machines, bicycles, motorcycles etc. In 1956, the ﬁrst

motor driven lawn mowers appeared, followed by chain saws in 1959, and it is within this area Husqvarna is working

today.

Today Husqvarna is one of the leading manufacturers in the world of forest and garden products, with quality as our

highest priority. We develop, manufacture and market high quality motor driven products for forestry and gardening as

well as for building and construction industry.

Your purchase gives you access to professional help with repairs and service whenever this may be necessary. If the

retailer who sells your machine is not one of our authorized dealers, ask for the address of your nearest servicing dealer.

It is our wish that you will be satisﬁed with your product and that it will be your companion for a long time. Think of this

operator′s manual as a valuable document. By following its′ content (using, service, maintenance etc) the life span and

the second-hand value of the machine can be extended. If you ever lend or sell this machine, make sure that the

borrower or buyer gets the operator′s manual, so they will also know how to properly maintain and use it.

Thank you for using a Husqvarna product.

Husqvarna AB has a policy of continuous product development and therefore reserves the right to modify the design and

appearance of products without prior notice.

GENERAL SAFETY PRECAUTIONS

Important

Personal protective equipment

IMPORTANT!

The machine is only designed for cutting branches and

twigs.

Incorrect or careless use of a hedge trimmer can turn it

into a dangerous tool that can cause serious or even

fatal injury. It is extremely important that you read and

understand the contents of this operator’s manual.

Never use a machine that has been modiﬁed in any way

from its original speciﬁcation.

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.

Never use the machine if you are tired, if you have drunk

alcohol, or if you are taking medication that could affect

your vision, your judgement or your co-ordination.

Wear personal protective equipment. See instructions

under the heading ”Personal protective equipment”.

GENERAL SAFETY PRECAUTIONS

position then the carburettor idle setting must be adjusted.

See instructions under the heading Maintenance.

Vibration damping system

Your machine is equipped with a vibration damping

system that is designed to reduce vibration and make

operation easier.

Stop switch

The machine′s vibration damping system reduces the

transfer of vibration between the engine unit/cutting

equipment and the machine′s handle unit.

Use the stop switch to switch off the engine.

Regularly check the vibration damping units for cracks or

deformation. Check that the vibration damping element is

undamaged and securely attached.

Hand guard

damage in people who have impaired

circulation. Contact your doctor if you

experience symptoms of overexposure

to vibration. Such symptoms include

numbness, loss of feeling, tingling,

pricking, pain, loss of strength, changes

in skin colour or condition.These

symptoms normally appear in the

ﬁngers, hands or wrists.The risk

increases at low temperatures.

(327HDA65, 327HE3)

The hand guard prevents hands from coming into contact

with the moving blades, for example, if the operator loses

grip on the front handle.

Mufﬂer

The mufﬂer is designed to keep noise levels to a minimum

GENERAL SAFETY PRECAUTIONS

In countries that have a warm and dry climate there is a

WARNING! Bear in mind that:

signiﬁcant risk of ﬁre.We therefore ﬁt certain mufﬂers with

a spark arrestor screen. Check whether the mufﬂer on

your machine is ﬁtted with this kind of screen.

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!

Blades

For mufﬂers it is very important that you follow the

instructions on checking, maintaining and servicing your

machine.

To ensure good cutting results it is important that the

contact pressure between the blades is correct. The

contact pressure is adjusted by turning the screws on the

underside of the bar clockwise as far as they will go.Then

turn the screws anticlockwise a 1/4 turn. Lock the screws

using the locking nut on the top of the bar. Check that the

screws are loose enough to allow the washers under the

screw heads to slide sideways.

Never use a machine that has a faulty mufﬂer.

Regularly check that the mufﬂer is securely attached to

the machine.

When the blades are correctly adjusted the play between

the blades should be 0,2–0,4 mm, measured at the

screws.

The edges of the blades are too hard to be ﬁled. Dull

blades should be sharpened using a grinder.

If the mufﬂer on your machine is ﬁtted with a spark

arrestor screen this must be cleaned regularly. A blocked

screen will cause the engine to overheat and may lead to

serious damage.

Replace the blades if they are bent or damaged.

Blade guard

(327HDA65)

The blade guard (A) is intended to protect against any

part of the body coming into contact with the blades (B).

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.

Check that the blade guard is not damaged or distorted.

Replace the blade guard if it is bent or damaged.

FUEL HANDLING

Gasoline

Fuel safety

Never start the machine:

If you have spilled fuel on it. Wipe off the spillage and

allow remaining fuel to evaporate.

CAUTION! Always use a quality gasoline/oil mixture with

an octane rating of at least 87 octane ((RON+MON)/2). If

your machine is equipped with a catalytic converter (see

chapter on Technical data) always use a good quality

unleaded gasoline/oil mixture. Leaded gasoline will

destroy the catalytic converter.

If 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.

If the machine is leaking fuel. Check regularly for

leaks from the fuel cap and fuel lines.

Use low-emission gasoline, also known as alkylate

gasoline, if it is available.

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.

This engine is certiﬁed to operate on unleaded

gasoline.

•

When storing and transporting fuel always use

approved containers intended for this purpose.

•

The lowest recommended octane grade is 87

((RON+MON)/2). If you run the engine on a lower

octane grade than 87 so-called knocking can occur.

This gives rise to a high engine temperature and

increased bearing load, which can result in serious

engine damage.

When storing the machine for long periods the fuel

tank must be emptied. Contact your local gas 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.

•

When working at continuous high revs a higher octane

rating is recommended.

The transport guard must always be ﬁtted to the

cutting attachment when the machine is being

transported or in storage.

Two-stroke oil

•

Secure the machine during transport.

•

For best results and performance use HUSQVARNA

two-stroke engine oil, which is specially formulated for

our air-cooled two stroke-engines.

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.

•

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.

Mixing ratio

WARNING!Take care when handling fuel.

Bear in mind the risk of ﬁre, explosion

FUEL HANDLING

Fueling

Mixing

•

Always mix the gasoline and oil in a clean container

intended for fuel.

•

Always start by ﬁlling half the amount of the gasoline

to be used. Then add the entire amount of oil. Mix

(shake) the fuel mixture. Add the remaining amount of

gasoline.

WARNING! Taking the following

precautions, will lessen the risk of ﬁre:

•

Mix (shake) the fuel mixture thoroughly before ﬁlling

the machine’s fuel tank.

Do not smoke or place hot objects near

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.

•

Do not mix more than one month’s supply of fuel at a

time.

•

Clean the area around the fuel cap. Contamination in

the tank can cause operating problems.

If the machine is not used for some time the fuel tank

should be emptied and cleaned.

Ensure that the fuel is well mixed by shaking the

container before ﬁlling the tank.

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

working near ﬂammable substances and/

or vapours.

Carburetor

ﬁrst few hours the machine is in use. The carburettor

should then be ﬁnely adjusted. Fine adjustment

should be carried out by a skilled technician.

Your Husqvarna product has been designed and

manufactured to speciﬁcations that reduce harmful

emissions. After the engine has used 8-10 tanks of fuel

the engine will be run-in.To ensure that it continues to run

at peak performance and to minimise harmful exhaust

emissions after the running-in period, ask your dealer/

service workshop (who will have a rev counter at their

disposal) to adjust your carburettor.

CAUTION! If the blades move while the engine is idling

the T screw should be turned anti-clockwise until they

stop.

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.

Function

Adjust the idle speed with the idle adjustment screw T, if

adjustment is necessary. First turn the idle adjustment

screw T clockwise until the blades start to move. Then

turn the idle adjustment screw T anticlockwise until the

blades stop.The idle speed is correctly adjusted when the

engine runs smoothly in every position.There should also

be a clear margin to the speed at which the blades start

to move.

•

The carburetor governs the engine’s speed via the

throttle control. Air and fuel are mixed in the

carburetor. The air/fuel mixture is adjustable. Correct

adjustment is essential to get the best performance

from the machine.

•

The setting of the carburetor means that the engine is

adapted to local conditions, for example, the climate,

altitude, fuel and the type of 2-stroke oil.

The carburetor has three adjustment controls:

L = Low speed jet

H = High speed jet

T = Idle adjustment screw

The blades must also remain stationary when the choke

control is in the start throttle position.

Rec. 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

•

The L and H-jets are used to adjust the supply of fuel

to match the rate that air is admitted, which is

controlled with the throttle. If they are screwed

clockwise the air/fuel ratio becomes leaner (less fuel)

and if they are turned anti-clockwise the ratio

becomes richer (more fuel). A lean mixture gives a

higher engine speed and a rich mixture gives a lower

engine speed.

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

The T-screw regulates the throttle setting at idle

speed. If the T-screw is turned clockwise this gives a

higher idle speed; turning it anti-clockwise gives a

lower idle speed.

cause ﬁre if directed against dry and combustible

material.

Cooling system

To keep the working temperature as low as possible the

machine is equipped with a cooling system.

Some mufﬂers are equipped with a special spark arrestor

screen. If your machine has this type of mufﬂer, you

should clean the screen at least once a week.This is best

done with a wire brush.

The cooling system consists of:

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 if necessary cleaned, monthly. If the

screen is damaged it should be replaced. If the screen

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

screen will cause the machine to overheat and result in

damage to the cylinder and piston.

Air intake on the starter.

Fins on the ﬂywheel.

Cooling ﬁns on the cylinder.

Cylinder cover (directs cold air over the cylinder).

Clean the cooling system with a brush once a week, more

often in demanding conditions. A dirty or blocked cooling

system results in the machine overheating which causes

damage to the piston and cylinder.

CAUTION! Never use a machine with a defective mufﬂer.

Spark plug

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.

The spark plug condition is inﬂuenced by:

•

Incorrect carburetor adjustment.

Remember the risk of ﬁre!

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 0.020 inch (0.5

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 HUSQVARNA 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.

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.

Air ﬁlter

The air ﬁlter must be regularly cleaned to remove dust

and dirt in order to avoid:

Gear

•

Carburettor malfunctions

Starting problems

Loss of engine power

Unnecessary wear to engine parts

Excessive fuel consumption.

There is a grease nipple and a plug for ﬁlling lubricant on

the gear housing. Use a grease gun to ﬁll with grease.

This should be done after every 60 working hours. Use

Husqvarna’s special grease, no. 503 98 96-01.

Clean the ﬁlter every 25 hours, or more regularly if

conditions are exceptionally dusty.

CAUTION! The gear housing must not be ﬁlled

completely with grease. The grease expands as the

machine heats up during operation. If the gear housing

was completely ﬁlled with grease it could damage the

seals and lead to leakage of grease.

The grease in the bevel gear does not normally need to

be changed except if repairs are carried out.

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
