Replace the guard if it has been exposed to impact or is cracked.
GENERAL SAFETY PRECAUTIONS If the mufﬂer on your machine is ﬁtted with a spark arrestor screen this must be cleaned regularly. A blocked screen will cause the engine to overheat and may lead to serious damage. WARNING! Mufﬂers ﬁtted with catalytic converters get very hot during use and remain so for some time after stopping.
GENERAL SAFETY PRECAUTIONS General rules Only use cutting attachments with the guards we recommend! See the chapter on Technical data. Keep the teeth of the blade correctly sharpened! Follow our instructions and use the recommended ﬁle gauge. An incorrectly sharpened or damaged blade increases the risk of accidents.

STARTING AND STOPPING Check before starting • Check the blade to ensure that no cracks have formed at the bottom of the teeth or by the centre hole. The most common reason why cracks are formed is that sharp corners have been formed at the bottom of the teeth while sharpening or that the blade has been used with dull teeth.
STARTING AND STOPPING CAUTION! Do not pull the starter cord all the way out and do not let go of the starter handle when the cord is fully extended. This can damage the machine. CAUTION! Do not put any part of your body in marked area. Contact can result in burns to the skin, or electrical shock if the spark plug cap has been damaged.
General working instructions IMPORTANT! This section describes the basic safety precautions for working with clearing saws and trimmers. 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.
WARNING! Machines ﬁtted with saw blades or grass blades can be thrown violently to the side when the blade comes into contact with a ﬁxed object. This is called blade thrust. A blade thrust can be violent enough to cause the machine and/or operator to be propelled in any direction, and possibly lose control of the machine.
Sweeping • The fan effect of the rotating cord can be used for quick and easy clearing up. Hold the cord parallel to and above the area to be swept and move the tool to and fro. • When cutting and sweeping you should use full throttle to obtain the best results.
