Failure to follow this procedure may result in injury to hand or fingers and may damage the starter mechanism. 5 10 feet 5a 6a Chain saw operating instructions For assembly follow the procedure in the appropriate section "Mounting Guide Bar and Chain" of this manual. DOLMAR chain, guide bar and sprocket must match each other (see the appropriate section in this manual). WARNING! Proper tension of the chain is extremely important. In order to avoid false setting the tensioning procedure must be followed as described in this manual. Always make sure the hexagonal nut(s) for the sprocket guard is (are) tightened securely after tensioning the chain. Check chain tension once more after having tightened the nuts and thereafter at regular intervals (always before starting to work). If the chain becomes loose while cutting, shut off the engine and then tighten. Never try to tighten the chain while the engine is running! Fueling Your DOLMAR saw uses on oil-gasoline mixture for fuel (see chapter "Fuel" of this manual). Important adjustments Important adjustments At correct idle speed, chain should not turn. For directions to adjust idle speed, see the appropriate section of this instruction manual. Do not use a saw with incorrect idle speed adjustment. Adjust the idle speed yourself according to the appropriate section of this manual. Have your DOLMAR dealer check your saw and make proper adjustments or repairs. Check the saw chain tension frequently, especially just after installing a new chain. New chains may stretch more during their initial use. A properly adjusted saw chain can be pulled freely around the guide bar by hand without sagging. Always stop the engine and wear gloves when checking or adjusting the chain tension. Working conditions Operateyourchainsawonlyoutdoors. Operatethe saw under good visibility and daylight conditions only. WARNING! Take extreme care in wet and freezing weather (rain, snow, ice). Put off the work when the weatheris windy, stormy or rainfall is heavy. Clear the areawhere you are working. WARNING! Avoid stumbling on obstacles such as stumps, roots or rocks and watch out for holes or ditches. Be extremely cautious when working on slopes or uneven ground. There is increased danger of slip ping on freshly debarked logs. Cutting instructions Always hold the saw firmly with both hands when the engine is running. Place your left hand on the tubular handle and your right hand on grip and throttle lever. Left-handers should follow these instructions too. 7 Wrap your fingers tightly around the handles, keeping the handles cradled between your thumb and forefinger (fig. 7). With your hands in this position, you can best oppose and absorb the push, pull and kickback forces of your saw without having it slip out of your grip (see section of reactive forces). Make sure your chain saw handle and grip are in good condition and free of moisture, pitch, oil or grease. Always start a cut with the chain running at full speed and the spike bar in contact with the wood. WARNING! Never use the saw with one hand. You cannot control reactive forces (see pages 10 to 12) and may lose control of the saw. 8 WARNING! Do not operate your chain saw in semi-throttle position. Cutting in this position does not permit the operator proper control of the saw or chain speed. WARNING! Never come too close to a rotating chain with your hands or body. WARNING! Do not cut any material other than wood or wooden objects. Use your chain saw for cutting only. It is not designed for prying or shoveling away limbs, roots or other objects. When sawing, make sure that the saw chain does not touch any foreign materials such as rocks, nails and the like (fig. 8). Such objects may be flung off, damage the saw chain or cause the saw to kickback. 10 Position the chain saw in such a way that your body is clear of the cutting attachment whenever the engine is running (fig. 10). Don’t put pressure on the saw when reaching the end of a cut. The pressure may cause the bar and rotating chain to pop out of the cut or kerf, go out of control and strike the operator or some other object. If the rotating chain strikes some other object a reactive force (see pages 11 to 13 ) may cause the chain to strike the operator. Reactive forces during the cut, including kickback WARNING! Reactive forces, that may occur during any cut are kickback, pushback and pull-in. Reactive forces can be dangerous! In any chain saw, the powerful force used to cut wood can be reversed (and work against the operator). If the rotating chain is suddenly stopped by contact with any solid object like a log or branch or is pinched, the reactive forces instantly occur. These reactive forces may result in loss of control which may, in turn, cause serious or fatal injury. An understanding of the causes of these reactive forces may help you avoid loss of control. The most common reactive forces are - kickback, - pushback, - pull-in. In order to keep control of your saw, always ma...
