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 carburettor settings. See pages 26-29.

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

IMPORTANT! If the carburettor 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.

!Under no circumstances should you modify the original design of the chain saw without approval from the manufacturer. Always use genuine spare parts. Unauthorized modifications or accessories may lead to serious injury or death.

!A chain saw is a dangerous tool if used carelessly or incorrectly and can cause serious, even fatal injuries. It is very important that you read and understand these instructions.
