SAFETY INSTRUCTIONS

GENERAL WORKING INSTRUCTIONS

This section takes up the basic safety precautions for working

with the power cutter. Follow these general working instructions,

but never use a machine without the possibility of calling for

help in the event of an accident.

Basic safety precautions

IMPORTANT INFORMATION! Never work with a power

cutter that is defective or incorrectly adjusted. Do not

work with a power cutter that is incomplete or where

assembly has not been carried out in a satisfactory

manner. Check that the cutting blade stops rotating

when the throttle is released. If you encounter a situation

where you are uncertain how to proceed you should ask

an expert.

Avoid all usage which you consider to be beyond your

capability.

•Check that no one is in the immediate vicinity when the

machine is started or while working with the machine to

ensure that people, animals or other things cannot affect your

control of the power cutter.

•Avoid usage in unfavourable weather conditions, for example,

thick fog, heavy rain, strong winds or extreme cold, etc. To

work in bad weather conditions is tiring and can create

dangerous circumstances, e.g. slippery surfaces.

•Never start to work with the power cutter before the working

area is clear and you have a firm foothold. Look out for any

obstacles with unexpected movement. Ensure when cutting

that no material can become loose and fall, causing operating

injury.Take great care when working on sloping ground.

•Make sure clothing and parts of the body do not come into

contact with the cutting blade when the engine is started.

•Maintain a safe distance from the cutting blade when the

engine is running.

•The blade guard should always be fitted when the engine is

running.

•Ensure that the working area is sufficiently illuminated to

create a safe working environment.

•Some working positions may create greater stress on the

operator.

•Check the cutting area for buried cables and wires.

WARNING! A safe distance from the power

cutter is 15 metres. You are responsible that

animals and onlookers are not in the working

area. Do not start to work with the power

cutter before the working area is clear and

you have a firm foothold.

•Start cutting with the engine at full throttle.

•Always hold the power cutter firmly, with both hands. Hold

the machine so that the thumb and fingers grip around the

handle.

Cutting

Only use the machine in areas with good

ventilation. Neglect can result in serious

injury or death.

Fuel safety

(Filling/Fuel mixture/Storage)

WARNING! Exercise great care when handling

fuel. Bear in mind the risk of fire, explosions

and inhaling fumes.

•Never fill the machine while

the engine is running.

•Provide good ventilation

when filling or mixing fuel

(gasoline and 2-stroke oil).

•Move the machine at least 3

m from the filling position

before starting.

•Never start the machine:

a) If you have spilt fuel

on it. Wipe up all

spillage.

b) If you have spilt fuel

on yourself or your

clothes. Change your

clothes.

c) If there is a fuel leak.

Make regular checks for

leakage from the fuel

cap and the fuel supply

pipes.

•Store the power cutter and fuel so that any leakage or fumes

do not risk coming into contact with sparks or naked flames.

For example, electric machines, electric motors, electrical

switches/power switches, heaters or the like.

•When storing fuel, approved containers intended for this

purpose must be used.

•When storing the power cutter for long periods the fuel tank

must be emptied. Contact your local fuel station to find out

how to dispose of excess fuel.

not overﬁll with fuel. Mop up any spills on the

ground or machine. If you spill fuel on yourself

or your cloths, change your clothes. Move the

machine at least 3 meters from the refuelling site

before starting.

8– English

Cutting technique

The technique described below is of a general character. Check

information for each blade regarding individual cutting characte-

ristics. (For example, a diamond blade requires less feeding

pressure than a abrasive blade).

1.Support the work piece

in such away that you

can predict what will

happen and so it will not

pinch.

2.Always cut at full throttle.

3.Start cutting gently, do

not force or squeeze the

blade in.

4.Use a high blade speed.

5.Move the blade slowly

backwards and forwards.

6.Use a small part of the

blade’s cutting edge.

7.Only use the blade’s

cutting edge when

cutting.

8.Cut with the blade fully

vertical – at right angles

to the work piece.

SAFETY INSTRUCTIONS

!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.

!WARNING!

Under all circumstances avoid cutting using

the side of the blade; it will almost certainly

be damaged, break and can cause immense

damage. Only use the cutting section.

!WARNING!

Do not lean the blade to the side, this can

cause the blade to jam or break with personal

injury as a consequence.

Water cooling

!WARNING! Water cooling, which is only used

for petrol-driven power cutters and when

cutting concrete, cools the cutting blade and

increases its service life as well as reduce

dust formation (see the section ”

Abrasive

blades

”). Among the disadvantages are

difficulties at very low temperatures, the risk

of damaging the floor and other sections of

the building and risk for slippage.

Sharpening diamond blades

Blades can become dull when the wrong feeding pressure is

used or when cutting some materials such as heavily reinforced

concrete. To force a dull blade results in overheating and finally

the loss of segments (part of the blade).

Sharpen against a soft material such as sandstone, silica or

haydite brick.

Blade vibration

The blade can become out of shape (not round) and vibrate if a

too high feeding pressure is used or if the blade is pressed into

the work piece.

A lower feeding pressure ought to stop the vibration. Otherwise

replace the cutting blade.

Kickback

Kickback can occur very suddenly and with great force. If the

following directives are not followed, it can result in serious or

even fatal injury.

If the sector of the blade illustrated below is used for cutting the

blade can start to climbing and kickback the power cutter

upwards and backwards towards the user with immense force.

How to avoid kickback

1.Never cut with the

segment illustrated in the

diagram.

2.Keep a good balance and

a firm foothold.

3.Use both hands and take

a firm grip with the thumb

and fingers around the

handle.

4.Keep the work piece at a

comfortable distance.

5.Use the cutter at full

throttle.

6.Take care when inserting

the blade in an existing

cut.

7.Never cut above shoulder

height.

8.Be alert to movement of

the work piece or anything

else that can occur, which

could cause the cut to

close and pinch the blade.

English –9

SAFETY INSTRUCTIONS

Pull in

Pull in occurs when the lower part of the blade is suddenly

stopped or when the cut closes. (To avoid this see the section

”

How to avoid kickback

” and

”Pinching/rotation”

below).

Pinching/rotation

Pinching occurs when the cut closes. The power cutter can be

drawn suddenly and powerfully downwards.

How to avoid pinching

Support the work piece in

such a way that the cut

remains open during the

cutting operation and when

the cut is finished.

Drying the blade

After using the blade with

water cooling, let the cutter

run for approx. half a minute

so that the blade dries.

If a damp blade is stored it

can become unbalance and

cause damage.

Check the speed of the

drive shaft

Use a tachometer regularly to

check the speed of the drive

shaft when the cutter is

running at working tempera-

ture and at full throttle without

a load. The maximum speed

is stated on the unit.

Care and storage

General

Husqvarna’s power cutters are robust and durable. However, as

they are used for high speed operations all servicing should be

carried out on time and as specified, so that the power cutter

always works effectively and safely.

Read this Operator’s Manual to determine which service

routines you can carry out and ensure that all other service

work is carried out by an authorised service workshop.

Power Cutter

Always handle the power cutter with care and store it with the

blade removed.

Blades

•All blades should be

removed from the cutter

after use and stored

carefully.

•Special care should be

taken with abrasive

blades.

•Blades must be stored on

a firm, level surface. If

blades are supplied with a

backing pad then a spacer

should be used to keep

them flat.

•Avoid moisture and

temperature extremes.

•Remove the blades before

the cutter is moved or

transported.

•Inspect new blades for

transport or storage

damage.

!WARNING!

If the speed is higher than that stated then the

unit must be adjusted by an authorised

service workshop before it is used.

SAFETY INSTRUCTIONS

CUTTING BLADES Abrasive blades

The cutting material in an abrasive blade consists of abrasive

corn that is held together by an organic bonding agent.

”Reinforced blades” are made up of a fabric or fibre base that

prevents total breakage at maximum working speed if the blade

should be cracked or damaged. (The term reinforced does not

refer to those cutting blades that are only reinforced around the

flange).

A cutting blade’s performance is determined by the type and

size of abrasive corn, and the type and hardness of the bonding

agent.

Characteristics that give the blade a shorter service life and

greater cutting capacity are said to make the blade ”softer”. A

blade with a longer service life and slower cutting capacity is a

blade with a ”harder” effect.

High quality cutting blades are normally more economical.

Lower quality cutting blades usually have an inferior cutting

capacity and shorter service life, which results in higher cost per

processed material.

General

Cutting blades are available in two standard designs; abrasive

blades and diamond blades.

!WARNING!

A cutting blade may burst and cause injury

to the operator.

High speed portable tools

Cutting blades of the make Husqvarna are manufactured for

portable, high speed, power cutters. If other makes of cutting

blades are used, ensure the blades comply with all the

directives and requirements attributed to the specific type of

power cutter.

WARNING!

Never exceed the maximum working speed of

a cutting blade.

Special blades

Some cutting blades are designed for stationary equipment and

for use with attachments. These types of cutting blades must

not be used on portable, power cutters.

WARNING!

Never use a cutting blade for any other

purpose than that it was intended for.

Always contact local authorities and make sure you are

following applicable directives.
