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. Set the switch to the "O" (STOP) position. 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. However when the possibility exists that icing may occur, the unit should be set to operate in the anti-freeze mode before use. Anti-freeze mode Normal operating mode Cylinder cover [Caution] Be sure to confirm brake operation during daily inspection. "Sunshine" mark "Snow" mark Continuing to use the product in the anti-freeze mode even when temperatures have risen and returned to normal, may result in the engine failing to start properly or in the engine failing to operate at its normal speed, and for this reason you should always be sure to return the unit to the normal operating mode if there is no danger of icing occurring. How to confirm: 1) Turn off the engine. 2) Holding the chain saw horizontally, release your hand from the front handle, hit the tip of the guide bar to a stump or a piece of wood, and confirm brake operation. Operating level varies by bar size. HOW TO SWITCH BETWEEN OPERATING MODES Cylinder cover Choke knob Icing cap In case the brake is not effective, ask our dealer for inspection and repairs. If the engine keeps rotating at high speed with the brake engaged, the clutch will overheat causing trouble.
