GENERAL SAFETY PRECA UTIONS

Steps bef ore using a new power cutter.

Please read the operator’s manual carefully.

• Check the assembly and adjustment of the cutting blade. See the instructions under the heading Assembling the cutting blade.

• Start the engine and check the idling setting, see instructions under the heading Maintenance. When the carburettor is set correctly the cutting blade should be still while idling. Setting of the idle speed is described under the heading Fine adjustment of the idle speed T. Set the correct speed according to these instructions. Do not use the power cutter if the idle speed is not adjusted correctly!

• Let your Husqvarna dealer regularly check the power cutter and make essential adjustments and repairs.

ARNING! Under no circumstances may the

design of the machine be modiﬁed without

the permission of the manufacturer. Always use genuine accessories. Non-authorized modiﬁcations and/or accessories can result in serious personal injury or the death of the operator or others.

ersonal protective equipment

ARNING! 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.

Protective helmet

• Hearing protection

• Protective goggles or a visor

• Breathing mask

ARNING! Use of products which cut, grind,

drill, sand or shape material can generate

dust and vapors which may contain harmful chemicals. Know the nature of the material being worked on and wear appropriate dust mask or respirator protection.

ARNING! A power cutter is a dangerous

tool if used carelessly or incorrectly and can

cause serious, even fatal injuries. It is extremely important that you read and understand the contents of this Operator’s Manual.

ARNING! The ignition system of this

machine produces an electromagnetic ﬁeld

during operation. This ﬁeld may under some circumstances interfere with pacemakers. To reduce the risk of serious or fatal injury, we recommend persons with pacemakers to consult their physician and the pacemaker manufacturer before operating this machine.

Husqvarna Construction Products has a policy of continuous product development. Husqvarna reserves the right to modify the design and appearance of products without prior notice and without further obligation introduce design modiﬁcations.

All information and all data in the Operator’s Manual were applicable at the time the Operator’s Manual was sent to print.

• Heavy-duty, ﬁrm grip gloves.

SAFETY INSTR UCTIONS

Mac hine ′′

This section descr ibes 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.

′′

s safety equipment

ARNING! Never use a machine that has faulty safety equipment! Carry out the inspection, maintenance and service routines listed in this section.

Vibration damping system

our machine is equipped with a vibration damping system that is designed to minimize vibration and make operation easier.

The machine ′ s vibration damping system reduces the transfer of vibration between the engine unit/cutting equipment and the machine ′ s handle unit.

The engine body, including the cutting equipment, is insulated from the handles by vibration damping units.

Stop s witch

Use the stop s witch to switch off the engine.

IMPOR TANT INFORMATION

or mufﬂers it is very important that you follow the instructions on checking, maintaining and servicing your machine. See instructions under the heading Checking, maintaining and servicing the machine’s safety equipment.

ARNING! The inside of the mufﬂer contain

chemicals that may be carcinogenic. Avoid

contact with these elements in the event of a damaged mufﬂer.

Thr ottle lockout

The throttle tr igger lock is designed to prevent accidental operation of the throttle. When the lock (A) is pressed in this releases the throttle (B).

The trigger lock remains pressed in as long as the throttle is pressed. When the grip on the handle is released the throttle trigger and the throttle trigger lock both return to their original positions. This is controlled by two independent return spring systems. This means that the throttle trigger is automatically locked in the idle position.

Mufﬂ er

ARNING! The mufﬂer gets very hot in use

and remains so for a short time afterwards.

Do not touch the mufﬂer if it is hot!

The m ufﬂer is designed to keep noise levels to a minimum and to direct exhaust fumes away from the user.

ARNING! 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!

Guar d for the blade

ARNING! Always check that the blade

guard is ﬁtted correctly before starting the

machine.

This guard is ﬁ tted above the cutting blade and is designed to prevent parts of the blade or cutting fragments from being thrown towards the user.

SAFETY INSTRUCTIONS

General safety precautions

• A power cutter is designed to cut hard materials, such as masonry. Observe the increased risk of kickback when cutting soft materials. See instructions under the heading How to avoid kickback.

• Do not use the power cutter until you have read the entire contents of this Operator’s Manual. All servicing, in addition to the points listed in the section ”Control, maintenance and service of the power cutter’s safety equipment”, should be carried out by trained service specialists.

• 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.

• Never use a machine that has been modiﬁed in any way from its original speciﬁcation.

• 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.

• Never allow anyone else to use the machine without ﬁrst ensuring that they have understood the contents of the operator’s manual.

• Never use the machine indoors. Be aware of the dangers of inhaling the engine’s exhaust fumes.

Transport and storage

Do not store or transport the power cutter with the cutting blade ﬁtted.

Store the power cutter in a lockable area so that it is out of reach of children and unauthorised persons.

All blades should be removed from the cutter after use and stored carefully. Store cutting blades in dry, frost free conditions.

Special care should be taken with abrasive discs. Abrasive discs must be stored on a ﬂat, level surface. If blades are supplied with a backing pad then a spacer should be used to keep them ﬂat. If an abrasive disc is stored in humid conditions, this can cause imbalance and result in injury.

Inspect new blades for transport or storage damage.

Fuel safety

(Refuelling/Fuel mixture/Storage.)

WARNING! Take care when handling fuel. Bear in mind the risk of ﬁre, explosion and

inhaling fumes.

• Never refuel the machine while the engine is running.

• Make sure there is plenty of ventilation when refuelling or mixing fuel (petrol and 2-stroke oil).

• Move the machine at least 3 m from the refuelling point before starting it.

• Never start the machine:

- If you have spilt fuel on it. Wipe off the spillage and allow

remaining fuel to evaporate.

- If you have spilt 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.

• 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.

• Always store fuel in an approved container designed for that purpose.

• When storing the machine for long periods the fuel tank must be emptied. Contact your local petrol station to ﬁnd out where to dispose of excess fuel.

• Always use a Husqvarna fuel container with an anti-spill valve.
