While holding the saw unit securely on the ground, pull the starter rope vigorously. Keep clear of the saw chain as it will start rotatIng upon starting of engine. ¦ CHECKING THE OIL SUPPLY Make sure to set up the bar and the chain when checking the oil supply. If not, the rotating parts may be exposed. It is very dangerous. After starting the engine, run the chain at medium speed and see if chain oil is scattered off as shown in the figure. (1) Chain oil The chain oil flow can be changed by inserting a screwdriver in the hole on bottom of the clutch side. Adjust according to your work conditions. (1) Rich (2) Lean (3) Chain oil flow adjusting ¦ ADJUSTING THE CARBURETOR (3) (2) (1) (1) L needle (2) H needle (3) Idle adjusting screw GB-9 G3300 / G3300EZ GB-10 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. 1. H and L needles are restricted within the number of turn as shown below. H needle : -1/4 L needle : -1/4 2. Start the engine and allow it to warm up in low speed for a few minutes. 3. Turn the idle adjusting screw (T) counterclockwise so that the saw chain does not turn. If the idling speed is too slow, turn the screw clockwise. 4. Make a test cut and adjust the H needle for best cutting power, not for maximum speed. 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. When the brake engages during operation, immediately release the throttle lever to stop the engine. ¦ STOPPING THE ENGINE 1. Release the throttle lever to allow the engine to idle for a few minutes. 2. Set the switch to the “O” (STOP) position. (1) ¦ 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 insulator 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. Stop the engine, remove the cylinder cover and install the grommet A to the appropriate position of the mode. See ¦ Maintenance part for how to remove the cylinder cover. (1) (2) (4) (5) (3) (5) ¦ 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. (1) (2) (3) [Caution] Be sure to confirm brake operation during daily inspection. 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. (1) Switch (1) Normal operation mode (2) Anti-freeze mode (3) Insulator (4) Carburetor (5) Grommet A (1) Release (2) Activate (3) Front guard G3300 / G3300EZ 6. Sawing ¦ GUARD AGAINST KICKBACK • Before proceeding to your job, read the section “For Safe Operation”. It is recommended to first practice sawing easy logs. This also helps you get accustomed to your unit. • Always follow the safety regulations. The cha...
