Now you are ready to pick up the saw. Use the proper grip for both handles, refer to “Operation” for additional information. STOPPING THE ENGINE See Figure 15. Release the throttle trigger and let the engine return to idle. To stop the engine, move the ignition switch to the “ ” stop position. Do not put the chain saw on the ground when the chain is still moving. 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. Important: When you are finished using the saw, relieve tank pressures by loosening the CHAIN OIL and FUEL MIX caps. Then retighten the caps. Allow the engine to cool before storing. STOPSTOPFig. 15 IGNITION SWITCH IN THE STOP POSITION Page 13 Page 14 PREPARING FOR CUTTING PROPER GRIP ON HANDLES See Figures 16 and 17. Refer to “Specific Safety Rules – Safety Apparel” earlier in this manual for appropriate safety equipment. Wear non-slip gloves for maximum grip and protection. Hold the saw firmly with both hands. Always keep your LEFT HAND on the front handle and your RIGHT HAND on the rear handle so that your body is to the left of the chain line. WARNING: Never use a left-handed (cross-handed) grip or any stance that would place your body or arm across the chain line. Maintain a proper grip on the saw whenever the engine is running. The fingers should encircle the handle and the thumb is wrapped under the handlebar. This grip is least likely to be broken (by a kickback or other sudden reaction of the saw). Any grip in which the thumb and fingers are on the same side of the handle is dangerous because a slight kick of the saw can cause loss of control. WARNING: DO NOT operate the throttle trigger with your left hand and hold the front handle with your right hand. Never allow any part of your body to be in the chain line while operating a saw. PROPER CUTTING STANCE See Figure 18. Balance your weight with both feet on solid ground. Keep left arm with elbow locked in a “straight arm” position to withstand any kickback force. Keep your body to the left of the chain line. Keep your thumb on underside of handlebar. CHAIN LINE PROPER GRIP STRAIGHT THUMB ON CHAIN LINE ARM UNDERSIDE OF HANDLE BAR Fig. 18 Fig. 16 Fig. 17 OPERATION OPERATION OPERATION Practice cutting a few small logs using the following technique to get the “feel” of using your saw before you begin a major sawing operation. 1. Take the proper stance in front of the wood with the saw idling. 2. Accelerate the engine to full throttle just before entering the cut by squeezing the throttle trigger. 3. Begin cutting with the saw against the log. 4. Keep the engine at full throttle the entire time you are cutting. 5. Allow the chain to cut for you; exert only light downward pressure. Forcing the cut could result in damage to the bar, chain, or engine. 6. Release the throttle trigger as soon as the cut is completed allowing the engine to idle. Running the saw at full throttle without a cutting load can result in unnecessary wear to the chain, bar, and engine. 7. Do not put pressure on the saw at the end of the cut. WORK AREA PRECAUTIONS See Figure 19. . 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 chain saw who has not read this operator's manual or received adequate instructions for the safe and proper use of this chain saw. . 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 feet (4.5m) between workers. Fig. 19 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 kickback 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 CARBURETOR See Figures 20 and 21. Before adjusting the carburetor, clean the air filter and the starter cover vents. Allow the engine to warm up prior to carburetor adjustment. Refer to “Maintenance” later in this manual. STOPSTOPThe carburetor is factory set and should not require adjusting. The carburetor will permit only limited adjustment of the “L” (Low Jet) and “H” (High Jet) needles. Any adjustment should be done by a Homelite Service Center. Under no circumstances should the “L” (Low Jet) and “H” (High Jet) needles be forced outside the range of adjustment. CAUTION: Serious damage can 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!
