[G3300] 1. Pull the guard towards the front handle to check that the chain brake is not engaged. 2. Loosen the nut and remove the chain cover. 3. Gear the chain to the sprocket and, while fitting the saw chain around the guide bar, mount the guide bar to the power unit. Adjust the position of the chain tensioner. (1) Power unit (2) Bar protector (3) Guide bar (4) Saw chain (5) Plug wrench Open the box and install the guide bar and the saw chain on the power unit as follows: The saw chain has very sharp edges. Use thick protective gloves for safety. Pay attention to the correct direction of the saw chain. (2) (3) (1) (1) Moving direction (2) Tensioner nut (3) Chain cover 4. Fit the chain cover to the power unit and fasten the nut to finger tightness. 5. While holding up the tip of the bar, adjust the chain tension by turning the tensioner screw until the tie straps just touch the bottom side of the bar rail. GB-6 G3300 / G3300EZ GB-7 GB [G3300EZ] 1. Pull the guard towards the front handle to check that the chain brake is not engaged. 2. Loosen the nut assembly and dismount the chain cover. (1) (2) (3) 3. Set the guide bar to the power unit, gear the chain to the sprocket of clutch drum and fit it into the groove of the bar and the sprocket at the tip of the bar. • Pay attention to the correct direction of the saw chain. • Make sure to fit the chain into the groove of the bar and the sprocket. If not, you may fail to tighten the chain. (2) (1) (3) (4) 4. Move the guide bar back and forth to adjust the position of projection A, B and C to fit in each hole. By inserting the projections into the bottom of holes, attach the chain cover securely.

Tighten the nut securely with the bar tip held up (12 ~ 15 N·m). Then check the chain for smooth rotation and proper tension while moving it by hand. If necessary, readjust with the chain cover loose. 7. Tighten the tensioner screw. Note: A new chain will expand its length in the beginning of use. Check and readjust the tension frequently as a loose chain can easily derail or cause rapid wear of itseif and the guide bar. While temporary tightening, you may hear the “click” sound. But do not stop tightening at that time. This sound does not mean that the saw chain and guide bar were assembled. 5. While holding the chain cover, temporary tighten the nut assembly and fix the bar and chain cover. (You can fix them even by tightening the lever.) Check if the saw chain fits on the bar rail. If not, readjust by loosen the nut assembly. (2) (1) (3) (4) (4) 6. After fixing them, attach the bar protector for your safety. Pull the lever up and tighten it securely. Tightening torque: 7.9 ~ 12.8 N·m {80~130kgf-cm} (1) (2) (3) 7. If the chain becomes loose while using the unit, attach the bar protector and loosen the nut assembly around 4 turns. Dismount the protector and check if the chain fits on the bar rail. If not, readjust by loosen the nut assembly. Temporary tighten the nut assembly. The chain is to be tensioned automatically. After fixing the guide bar, mount the protector and tighten the lever securely for fully tightening. (1) (2) NOTE: A new chain will expand its length in the beginning of use. Check and readjust the tension frequently as a loose chain can easily derail or cause rapid wear of itself and the guide bar. • Replace the guide plate when its file is worn.

Fuel and Chain Oil ¦ FUEL • Gasoline is very flammable. Avoid smoking or bringing any flame or sparks near fuel. Make sure to stop the engine and allow it cool before refueling the unit. Select outdoor bare ground for fueling and move at least 3 m (10 ft) away from the fueling point before starting the engine. • The Komatsu Zenoah engines are lubricated by oil specially formulated for air-cooled 2-cycle gasoline engine use. If Komatsu Zenoah oil is not available, use an anti-oxidant added quality oil expressly labeled for air-cooled 2-cycle engine use (JASO FC GRADE OIL or ISO EGC GRADE). • Do not use BIA or TCW (2-stroke water-cooling type) mixed oil. ¦ RECOMMENDED MIXING RATIO GASOLINE 50 : OIL 1 • Exhaust emission are controlled by the fundamental engine parameters and components (eq., carburation, ignition timing and port timing) without addition of any major hardware or the introduction of an inert material during combustion. • These engines are certified to operate on unleaded gasoline. • Make sure to use gasoline with a minimum octane number of 89RON (USA/Canada: 87AL). • If you use a gasoline of a lower octane value than prescribed, there is a danger that the engine temperature may rise and an engine pro...
