Moreover, normal wear and change in product with no functional influence are not covered by the warranty. Also, be careful that, if the usage in the instruction manual is not observed as to the mixed gasoline, etc. described therein, it may not be covered by the warranty. ¦ SUPPLYING CHAIN OIL WARNING Running the equipment for long hours with its chain oil run out will accelerate the wear and tear of the chain and guide bar, possibly resulting further in a chain cut and even in a fatal accident leading to death. 1. For chain oil, use a type that is sufficiently viscous and adequately lubricating under the summer-use conditions and another type that shows similar performance under the winter-use conditions. 2. The use of Zonoah genuine chain oil is recommended to make your chain saws last as long as possible. If no genuine chain oil is available, please use commercially available chain oil, which is commonly used. CAUTION Using waste oil, recycled oil, or anything similar causes a breakdown and also proves harmful to the human body and environment. Please do not under any circumstances use any such material. IMPORTANT Use chain oil of vegetable origin. Before storing it for a long period, remove the chain oil from the blade and chain groove and clean them. If not, the chain may become rusted. Chain rust will cause the chain to become rigid or to become viscous at the tip. G2500 5. Operating the Engine WARNING It is very dangerous to run a chainsaw that mounts broken parts or lacks any parts. Before starting engine, make sure that all the parts including bar and chain are installed properly. ¦ STARTING THE ENGINE 1. Fill fuel and chain oil tanks respectively, and tighten the caps securely. Fuel Chain oil 2. Continuously push the priming bulb until fuel comes in the bulb. 3. Set the switch to “I” position. Throttle Switch interlock Throttle lever 4. Pull out the choke knob to the second-stage position. The choke will close and the throttle lever will then be set in the starting position. Choke When the engine is cool knob When the engine is warm up After the engine starts NOTE When restarting immediately after stopping the engine, set the Choke knob in the first-stage position (choke open and throttle lever in the starting position). Once the choke knob has been pulled out, it will not return to the operating position even if you press down on it with your finger. When you wish to return the choke knob to the operating position, pull out the throttle lever instead. 5. While holding the saw unit securely on the ground, pull the starter rope vigorously. G B WARNING Do not start the engine while the chain saw hangs in one hand. The saw chain may touch your body. This in very dangerous. 6. When engine has ignited, first push in the choke knob to the first-stage position and then pull the starter again to start the engine. 7. Allow the engine to warm up with the throttle lever pulled slightly. ¦ CHECKING THE OIL SUPPLY WARNING 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. 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. Rich Chain oil flow Lean adjusting shaft The oil tank should become nearly empty by the time fuel is used up. Be sure to refill the oil tank every time when refueling the saw. GB-11 G2500 ¦ ADJUSTING THE CARBURETOR WARNING Idle adjusting screw H needle L needle 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. ¦ CHAIN BRAKE The chain brake is a device which stops the chain instantaneously if the chain saw recoils due to kickback. Normally, the brake is activated automatically by inertial force. It can also be activated manually by pushing the brake lever (left-hand guard) down toward the front. When the brake operates, a yellow cone pops up from the base of the brake lever. Releasing the Brake Pull the brake lever up toward the left-hand handle until it clicks into place. • When the brake operates, release the throttle lever to slow down the engine speed.
