death for the operator or bystanders if the

instructions in the manual are not obeyed.

General safety instructions

WARNING: Read the warning instructions

that follow before you use the product.

• A clearing saw, brushcutter or trimmer can be

dangerous if used carelessly or incorrectly and can

cause serious injury or death to the operator or

others. It is extremely important that you read and

understand the contents of this operator’s manual.

• Under no circumstances may the design of the

product be modified without the permission of the

manufacturer. Never use a product that has been

modified in any way from its original specification

and always use original accessories. Non-authorized

modifications and/or accessories can result in

serious personal injury or the death of the operator

or others.

• The inside of the muffler contain chemicals that may

be carcinogenic. Avoid contact with these elements

in the event of a damaged muffler.

• This product produces an electromagnetic field

during operation. This field may under some

circumstances interfere with active or passive

medical implants. To reduce the risk of serious or

fatal injury, we recommend persons with medical

implants to consult their physician and the medical

implant manufacturer before operating this product.

Safety instructions for operation

WARNING: Read the warning instructions

that follow before you use the product.

• You must understand the difference between grass

clearing and grass trimming before use.

• If you encounter a situation where you are uncertain

how to proceed you should ask an expert. Contact

your dealer or your service workshop. Avoid all

usage which you consider to be beyond your

capability.

• Never use a product that is faulty. Carry out the

safety checks, maintenance and service instructions

described in this manual. Some maintenance and

service measures must be carried out by trained and

qualified specialists. Refer to 

Maintenance on page

19

.

• All covers, guards and handles must be fitted before

you start the product. Ensure that the spark plug cap

and ignition lead are undamaged to avoid the risk of

electric shock.

• Never use the product if you are fatigued, while

under the influence of alcohol or drugs, medication

or anything that could affect your vision, alertness,

coordination or judgement.

• Do not use the product in bad weather such as

dense fog, heavy rain, strong wind, intense cold,

etcetera. Working in bad weather is tiring and often

brings added risks, such as icy ground,

unpredictable felling direction, etcetera.

• The only accessories you can operate with this

engine unit are the cutting attachments that we

recommend. Refer to 

Accessories on page 26

.

• Never allow children to use or be in the vicinity of the

product. As the product is equipped with a spring-

loaded start/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 product. This can mean

a risk of serious personal injury. Therefore remove

the spark plug cap when the product is not under

close supervision.

• Running an engine in a confined or badly ventilated

area can result in death due to asphyxiation or

carbon monoxide poisoning.
