SAFETY INSTRUCTIONS

Vibration damping system

Your 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 vibrations.

WARNING! Overexposure to vibration can lead to circulatory damage or nerve damage

in people who have impaired circulation. Contact your doctor if you experience symptoms of overexposure to vibration. Such symptoms include numbness, loss of feeling, tingling, pricking, pain, loss of strength, changes in skin colour or condition. These symptoms normally appear in the ﬁngers, hands or wrists. The risk increases at low temperatures.

Mufﬂer

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

WARNING! Bear in mind that:

Engine exhaust fumes contain carbon

monoxide, which can cause carbon monoxide poisoning. For this reason you should 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 indoors or near combustible material!

WARNING! The inside of the mufﬂer contain chemicals that may be carcinogenic. Avoid

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

Checking, maintaining and servicing

s safety

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 mesh. Check whether the mufﬂer on your machine is ﬁtted with this kind of mesh.

For 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.

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. Remember the risk of ﬁre!

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.

Stop switch

• Start the engine and make sure the engine stops when you move the stop switch to the stop setting.
