Before using a new saw

•Read the instructions carefully.

•Check cutting equipment is correctly fitted and adjusted. See page 25.

•Refuel and start the saw. Check the carburetor settings. See pages 26-29.

•Do not use the saw until sufficient chain oil has reached the chain, see page 14.

IMPORTANT! If the carburetor mixture is too lean it greatly increases the risk of engine failure.

Poor maintenance of the air filter will cause carbon build-up on the spark plug and lead to difficult starting.

If the chain is badly adjusted it will cause increased wear or damage to the bar, drive sprocket and chain.

Maintenance, replacement, or repair of the emission control devices and systems may be performed by any nonroad engine repair establishment or individual.

!WARNING!

Under no circumstances may the design of the machine be modified without the permis- sion of the manufacturer. Always use genuine spare parts/accessories. Non-authorized modifications and/or accessories can result in serious personal injury or the death of the operator or others.

Your warranty does not cover damage or liability caused by the use of non-authorized accessories or replacement parts.
