English Fig. R Fig. U 2 11 2nd CUT OVERBUCK (2/3DIAMETER) TO MEET 1st CUT (TO AVOID PINCHING) 1st CUT UNDERBUCK (1/3 DIAMETER) AVOID SPLINTERING Bucking WARNING: Recommend that first time users should practice cutting on a saw horse. Cutting a felled tree or log into lengths. How you should cut depends on how the log is supported. Use a saw horse (see Figure S) whenever possible. Fig. S • Figure V- When supported at both ends. First, cut 1/3 down from the top overbuck. Then make the finished cut by underbucking the lower 2/3 to meet the first cut. Fig. V 1st CUT OVERBUCK (1/3 DIAMETER) TO AVOID SPLINTERING 2nd CUT UNDERBUCK (2/3 DIAMETER) TO MEET 1st CUT (TO AVOID PINCHING) • Always start a cut with the chain running at full speed. • Place the bottom spike 22 of the chain saw behind the area of the initial cut as shown in Figure T. • Turn the chain saw on then rotate the chain and bar down into the tree, using the spike as a hinge. • Once the chain saw gets to a 45 degree angle, level the chain saw again and repeat steps until you cut fully through. • When the tree is supported along its entire length, make a cut from the top (overbuck), but avoid cutting the earth as this will dull your saw quickly. Fig. T 22 CUT FROM TOP (OVERBUCK) AVOID CUTTING EARTH • Figure U- When supported at one end First, cut 1/3 the diameter from the underside (underbuck). Then make the finishing cut by overbucking to meet the first cut. • When on a slope always stand on the uphill side of the log. When "cutting through", to maintain complete control reduce the cutting pressure near the end of the cut without relaxing your grip on the chain saw handles. Don't let the chain contact the ground. After completing the cut, wait for the saw chain to stop before you move the chain saw. Always stop the motor before moving from cut to cut. CARE AND MAINTENANCE Use only mild soap and damp cloth to clean the tool. Do not use solvents to clean the plastic housing of the saw. Never let any liquid get inside the tool; never immerse any part of the tool into a liquid. IMPORTANT: To assure product SAFETY and RELIABILITY, repairs, maintenance and adjustment should be performed by a DeWALT authorized service center, always using identical replacement parts. Regular maintenance ensures a long effective life for your chain saw. Chain and Bar After every few hours of use, remove the sprocket cover, guide bar and chain and clean thoroughly using a soft bristle brush. Ensure oiling hole on bar is clear of debris. When replacing dull chains with sharp chains it is good practice to flip the chain bar from bottom to top. Saw Chain Sharpening CAUTION: Sharp chain. Always wear protective gloves when handling the chain. The chain is sharp and can cut you when it is not running. 14
