While holding the saw unit securely on the ground, pull the starter grip until the engine attempts to start, but no more than 5 times. The carburetor on your unit has been factory adjusted, but may require fine tuning due to a change in operating conditions. Before adjusting the carburetor, make sure that the provided air/fuel filters are clean and fresh and the fuel properly mixed. When adjusting, take the following steps: Note: Be sure to adjust the carburetor with the bar chain attached. Do not start the engine while the chain saw hangs in one hand. This in very dangerous. GB-9 GZ400 Fine adjustment of the idling speed T Adjust the idle speed with the T-screw. If it is necessary to readjust, turn the T-screw clockwise while the engine is running, until the chain starts to rotate. A correctly adjusted idle speed setting occurs when the engine runs smoothly in every position. It should also be good margin to the rpm when the chain starts to rotate. STOPPING THE ENGINE 1. Release the throttle lever to allow the engine to idle for a few minutes. Switch T-screw Contact your servicing dealer, if the idle speed setting cannot be adjusted so that the chain stops. Do not use the chain saw until it has been properly adjusted or repaired. [Important] Do not put the chain saw on the ground when the chain is still moving. For additional safety, set the chain brake when the saw is not in use. In the event that the ignition switch will not stop the saw, pull the choke knob out to the fully extended position "FULL CHOKE" and engage chain brake to stop the engine. If the ignition switch will not stop the saw when set to the "STOP" position, have the ignition switch repaired before using the chain saw again to prevent unsafe conditions or serious injury. Note: When you are finished using the saw, always re lieve tank pressure by loosening, then retightening, the chain oil and fuel mix caps. Allow the engine to cool before storing. CHAIN BRAKE This machine is equipped with an automatic brake to stop saw chain rotation upon occurrence of kickback during saw cutting. The brake is automatically operated by inertial force, which acts on the weight fitted inside the front guard. This brake can also be operated manually with the front guard turned down to the guide bar. To release the brake, pull up the front guard toward the front handle till a "click" sound is heard. Carburetor anti-freeze mechanism Operating chain saws in temperatures of 0 ­ 5°C at times of high humidity may result in ice forming within the carburetor, and this in turn may cause the output power of the engine to be reduced or for the engine to fail to operate smoothly. This product has accordingly been designed with a ventilation hatch on the right side of the surface of the cylinder cover to allow warm air to be supplied to the engine and to thereby prevent icing from occurring. Under normal circumstances the product should be used in the normal operating mode, i. e. , in the mode to which it is set at the time of shipment.
