GENERAL SAFETY PRECAUTIONS

Cutting equipment

Grass blades and grass cutters are in-

tended for cutting coarse grass.

A trimmer head is intended for trimming

grass.

Blade retainer nut

A blade retainer nut is used to secure

some types of cutting attachment.

When fitting, tighten the nut in the opposite

direction to the direction of rotation of the

cutting attachment. To remove it, undo the

nut in the same direction as the cutting

attachment rotates.

CAUTION!

The nut

has a left--hand thread. Tighten the nut

using the wrench (provided).

WARNING:

Engine exhaust

fumes contain carbon monoxide,

which can cause carbon monoxide

poisoning. DO NOT start or run the

machine indoors, or anywhere that

is poorly ventilated. The exhaust

fumes from the engine are hot and

may contain sparks which can start

a fire. Never start the machine in-

doors or near combustible material!

IMPORTANT!

Only use cutting attachments with the guards

we recommend! See the section on

“Technical data”.

Refer to the instructions for the cutting attach-

ment to check the correct way to load the

trimmer line and the correct line diameter.

Maintain the correct blade setting! Follow our

instructions and recommendations.

WARNING:

Always stop the en-

gine 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

lead from the spark plug before

you start to work on it.

WARNING:

Using an incorrect

cutting attachment increases the

risk of blade thrust.

Cutting equipment

This section describes how to choose and

maintain your cutting equipment in order to:

Reduce the risk of blade thrust.

Obtain maximum cutting performance.

Extend the life of cutting equipment.

CAUTION:

Mufflers fitted with catalyt-

ic 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. Remem-

ber the risk of fire!

WARNING:

The inside of the

muffler contains chemicals that may

be carcinogenic. Avoid contact with

these elements in the event of a

damaged muffler.
