CAUTION: • Prevent the oil from coming into contact with the skin and eyes. Contact with the eyes causes irritation. In the event of eye contact, flush the affected eye immediately with clear water, then consult a doctor at once. • Never use waste oil. Waste oil contains carcinogenic substances. The contaminants in waste oil cause accelerated wear of the oil pump, the bar and the chain. Waste oil is harmful to the environment. • When filling the chain saw with chain oil for the first time, or refilling the tank after it has been completely emptied, add oil up to the bottom edge of the filler neck. The oil delivery may otherwise be impaired. 1 2 1. Oil filler cap 2. Strap 014386 To fill the oil, perform the following steps: 1. Clean the area around the oil filler cap thoroughly to prevent any dirt from entering the oil tank. 2. Unscrew the oil filler cap and add oil up to the lower edge of the filler neck. 3. Screw the oil filler cap firmly back in place. 4. Wipe away any spilt chain oil carefully. NOTE: • When the chain saw is used for the first time, it may take up to two minutes for the saw chain oil to begin its lubricating effect upon the saw mechanism. Run the saw without load until it does so (see "CHECKS ").

Check the chain tension frequently, as new chains are subject to elongation. Excessively high tension of saw chain may cause breakage of saw chain, wear of the guide bar and breakage of the adjusting dial. A chain which is too loose can jump off the bar, and therefore presents an accident risk. If the chain is too loose: Refer to the section titled "Adjusting saw chain tension" and adjust the saw chain tension again. Checking the switch action CAUTION: Before plugging in the tool, always check to see that the switch trigger actuates properly and returns to the "OFF" position when released. To prevent the switch trigger from being accidentally pulled, a lock-off button is provided. To start the tool, depress the lock-off button and pull the switch trigger. Release the switch trigger to stop. Do not pull the switch trigger hard without depressing the lock-off button. This may cause switch breakage. Checking the chain brake NOTE: • If the chain saw fails to start, check whether the chain brake is released. To release the chain brake, pull the hand guard backwards firmly until you feel it engage. 3 2 1. Front hand guard 2. Lock 1 3. Unlock 014387 12
