Checking the chain brake Do not work with the chain saw without first checking the chain brake! - Grasp the tubular handle firmly with one hand and hold the 1 grip with the other. - Start the motor as described (make sure you have a good footing, and place the chain saw on the ground in such a way that the guide bar is free of contact). - Switch on the motor and press the hand guard (1) in the direction of the arrow with the back of your hand until the chain brake engages. The chain should stop immediately. - Switch the motor off Immediately and release the chain brake. Important: If the saw chain does not stop instantly when you carry out this test, do not under any circumstances C use the saw! Take the chain saw to a MAKITA service center. Testing the run-out brake Do not work with the saw without first testing the run-out brake! - Grasp the tubular handle firmly with one hand and hold the grip with the other. - Start the motor as described (make sure you have a good footing, and place the chain saw on the ground in such a way that the guide bar is free of contact). - Switch the motor on and then back off. The chain should come to a full stop within two second of switching off the motor. Important: If the saw chain does not stop within two second when you carry out this test, do not use the saw! Inspect the carbon brushes (see page 19). D Checking the chain lubrication Never saw when a sufficient chain lubrication is not guaranteed. Otherwise the life of the sawing device will be reduced. Before starting work check the oil level in the tank and the oil feeding. Check the fed oil quantity by following the instructions below: - Start the electric chain saw. - Hold the running chain saw approx. 15 cm above a trunk or the ground (use an appropriate surface). If the lubrication is sufficient, you will see a light oiltrace because oil will be centrifuged from the chain saw. Pay attention to the direction the wind is blowing and avoid unnecessary exposure E to the oil spray! 14
