¦ ¦¦¦¦¦Cut only wood or materials made from wood; no sheet metal, no plastics, no masonry, no non-wood building materials. ¦ ¦¦¦¦¦Never allow children to operate your saw. Allow no person to use this chainsaw who has not read this operator’s manual or received adequate instructions for the safe and proper use of this chainsaw. ¦ ¦¦¦¦¦Keep everyone – helpers, bystanders, children, and animals, a SAFE DISTANCE from the cutting area. During felling operations, the safe distance should be a least twice the height of the largest trees in the felling area. During bucking operations, keep a minimum distance of 15 ft (4.5 m). between workers. ¦ ¦¦¦¦¦Always cut with both feet on solid ground to prevent being pulled off balance. ¦ ¦¦¦¦¦Do not cut above chest height as a saw held higher is difficult to control against kick-back forces. ¦ ¦¦¦¦¦Do not fell trees near electrical wires or buildings. Leave this operation for professionals. ¦ ¦¦¦¦¦Cut only when visibility and light are adequate for you to see clearly. ADJUSTING THE CARBURETTOR See Figures 22, 23, and 24. Before adjusting the carburettor, clean the air filter (A) and the starter cover vents (B). Allow the engine to warm up prior to carburettor adjustment. Refer to “Maintenance” later in this manual. The carburettor is factory set and should not require adjusting. The carburettor will permit only limited adjustment of the “L” (Low Jet) and “H” (High Jet) needles. Any adjustment should be done by a Ryobi service dealer. Under no circumstances should the “L” (Low Jet) and “H” (High Jet) needles be forced outside the range of adjustment. CAUTION: Serious damage may occur to the engine if improper adjustments are made to the “L” and “H” needles. Do not force the “L” and “H” needles outside the adjustment range! 11 UK OPERATION OPERATION ADJUSTING IDLING SPEED See Figure 24. ¦ ¦¦¦¦¦If the engine starts, runs, and accelerates but will not idle, turn the idling speed screw “T” clockwise to increase idling speed. ¦ ¦¦¦¦¦If the chain turns at idle, turn the idling speed screw “T” anticlockwise to reduce the idle RPM and stop the chain movement. If the saw chain still moves at idling speed, contact a Ryobi service dealer for adjustment and discontinue use until the repair is made. WARNING: THE SAW CHAIN SHOULD NEVER TURN AT IDLE. Turn the idling speed screw “T” anticlockwise to reduce the idle RPM and stop the chain, or contact a Ryobi service dealer for adjustment and discontinue use until the repair is made. Serious personal injury may result from the saw chain turning at idle. OPERATING THE CHAIN BRAKE See Figures 25 and 26. Refer to “Safety” earlier in this manual for additional information. Check the operating condition of the chain brake prior to each use. 1. Start the engine and grasp the front and rear handles securely with both hands. 2. Pull the throttle trigger to bring the chainsaw up to full speed. Using the back of your left hand, engage the chain brake (A) by pushing the chain brake lever/hand guard toward the bar while the chain is rotating rapidly. See Figure 25. NOTE: The chain brake should engage and stop the chain immediately. If not, stop the saw by placing the ignition switch in the “O” stop position. Take the saw to a Ryobi service dealer for repair and discontinue use until the repair is made. 3. Reset the chain brake back into the RUN position (B) by grasping the right-hand side (from operator’s position) of the chain brake lever/hand guard and pull towards the front handle until you hear a click. See Figure 26. FELLING TREES - HAZARDOUS CONDITIONS See Figure 27. WARNING: Do not fell trees during periods of high wind or heavy precipitation. Wait until the hazardous weather has ended. When felling a tree, it is important that you heed the following warnings to prevent possible serious injury. ¦ ¦¦¦¦¦Wear eye, hearing, and head protection (A) when operating this equipment. ¦ ¦¦¦¦¦Do not cut down trees having an extreme lean or large trees with rotten or dead limbs, loose bark, or hollow trunks. Have these trees pushed or dragged down with heavy equipment, then cut them up. ¦ ¦¦¦¦¦Consider the distribution and weight of heavy limbs (B). ¦ ¦¦¦¦¦Clear out the undergrowth around the tree to be felled (C). ¦ ¦¦¦¦¦Do not cut trees near electrical wires or buildings (D). ¦ ¦¦¦¦¦Consider the direction in which the tree leans (E). ¦ ¦¦¦¦¦Check the tree for damaged or dead branches which could fall and hit you during felling (F). ¦ ¦¦¦¦¦Periodically glance at the top of the tree during the back-cut to assure the tree is going to fall in the desired direction. ¦ ¦¦¦¦¦Keep all bystanders at a safe distance (G) (at least twice the height of the tree). ¦ ¦¦¦¦¦Prepare a path of safe retreat (H). ¦ ¦¦¦¦¦If the tree starts to fall in the wrong direction, or if the saw gets caught or hung up during the fall, leave the saw and save yourself! ¦ ¦¦¦¦¦Consider the wind direction before felling a tree. ¦ ¦¦¦¦¦Do not fell trees near power lines or near buildings which c...
