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.

GENERAL SAFETY PRECAUTIONS

Important

WARNING! Never allow children to use or

be in the vicinity of the machine. As the

machine is equipped with a spring-

loaded 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.

IMPORTANT!

The machine is only designed for trimming grass.

The only accessories you can operate with this engine

unit are the cutting attachments we recommend in the

chapter on Technical data.

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”.

Personal protective equipment

Never use a machine that has been modiﬁed in any way

from its original speciﬁcation.

IMPORTANT!

Never use a machine that is faulty.Carry out the 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 heading Maintenance.

A clearing saw, brushcutter or 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.

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.

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.

The machine operator must ensure that no people or

animals come closer than 15 metres 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 metres.

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.

Do an overall inspection of the machine before use, see

maintenance schedule.

GENERAL SAFETY PRECAUTIONS

GLOVES

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.

Gloves should be worn when necessary, e.g., when ﬁtting

cutting attachments.

Throttle lockout

BOOTS

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.

Wear sturdy, non-slip boots.

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.

Make sure the throttle control is locked at the idle setting

when the throttle lockout is released.

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.

Press the throttle lockout and make sure it returns to its

original position when you release it.

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 servicing dealer.

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.

Check that the throttle trigger and throttle lockout move

freely and that the return springs work properly.

GENERAL SAFETY PRECAUTIONS

See instructions under the heading Start. Start the

Mufﬂer

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.

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.

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 screen. Check whether the mufﬂer on

your machine is ﬁtted with this kind of screen.

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.

For mufﬂers it is very important that you follow the

instructions on checking, maintaining and servicing your

machine.

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.

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 screen this must be cleaned regularly. A blocked

screen will cause the engine to overheat and may lead to

serious damage.

GENERAL SAFETY PRECAUTIONS

Trimmer head

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.

IMPORTANT!

Always ensure the trimmer cord is wound tightly and

evenly around the drum, otherwise the machine will

generate harmful vibration.

Remember the risk of ﬁre!

•

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.

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!

•

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.

Cutting equipment

This section describes how to choose and maintain your

cutting equipment in order to:

The length of the cord is also important. A longer cord

requires greater engine power than a shorter cord of

the same diameter.

•

Reduce the risk of blade thrust.

•

Make sure that the cutter on the trimmer guard is

intact.This is used to cut the cord to the correct length.

Obtain maximum cutting performance.

Extend the life of cutting equipment.

To increase the life of the cord it can be soaked in

water for a couple of days. This will make the line

tougher so that it lasts longer.

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.

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

HT lead from the spark plug before you

start to work on it.

WARNING! A faulty cutting attachment

may increase the risk of accidents.
