3 READ ALL INSTRUCTIONS BASIC SAFETY PRECAUTIONS ■ Do not operate a chain saw with one hand! Use a firm grip with thumbs and fingers encircling the chain saw handles. Serious injury to the operator, helpers, bystanders, or any combination of these persons may result from one-handed operation. A chain saw is intended for two-handed use. ■ Always[...]

4 KICKBACK See Figures 1 and 2. ■ WARNING: Kickback may occur when the moving chain contacts an object at the upper portion of the tip of the guide bar or when the wood closes in and pinches the saw chain in the cut. Contact at the upper portion of the tip of the guide bar can cause the chain to dig into the object and stop the chain for an insta[...]

5 IMPORT ANT SAFETY INSTRUCTIONS PULL PUSH Fig. 3 ■ Push and Pull - This reaction force is always opposite to the direction the chain is moving where wood contact is made. Thus, the operator must be ready to control the PULL when cutting on the bottom edge of the bar, and PUSH when cutting along the top edge. See Figure 3. IN THE CUTTING/WORK ARE[...]

6 UNDERSTANDING YOUR CHAIN SAW SAFETY DEVICES See Figure 4. SAFE-T-TIP® Anti-Kickback Nose Guard The SAFE-T -TIP® prevents kickback from happening, because it covers the tip of the bar where kickback is generated. Never attempt any kind of cutting where the SAFE-T -TIP® would have to be removed from the bar tip. BATTERY SAFETY ■ Battery operat[...]

16 3. Maintain a proper grip on the saw whenever the unit is running. The fingers should encircle the handle and the thumb is wrapped under the handle- bar. 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 sl[...]

17 Fig. 13 PROPER CUTTING STANCE See Figure 13. ■ Weight should be balanced with both feet on solid ground. ■ Keep left arm with elbow locked in a "straight arm" position to withstand any kickback force. ■ Your body should always be to the left of the chain line. ■ Thumb should be on underside of handlebar.

18 W ARNING: 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! ■ Felling a tree - When bucking and felling operations are being performed by two or more persons, at the same time, the felling operation should be sepa- rated from the bucking operation by a dist[...]

19 ■ Felling Backcut. The backcut is always made level and horizontal, and at a minimum of 2 inches (5 cm) above the horizontal cut of the notch. See Figures 15 and 16. ■ Never cut through to the notch. Always leave a band of wood between the notch and backcut (approximately 2 inches (5 cm) or 1/10 the diameter of the tree). This is called &quo[...]

Note that the saw will tend to pull away from you. UNDERBUCKING Begin on the under side of the log with the top of the saw against the log; exert light pressure upward. During underbucking, [...]

22 PRUNING See Figure 23. Pruning is trimming limbs from a live tree. ■ Work slowly, keeping both hands on the chain saw with a firm grip. Always make sure your footing is secure and your weight is distributed evenly on both feet. ■ Do not cut from a ladder, this is extremely danger- ous. Leave this operation for professionals. ■ Do not cut a[...]

25 CHAIN TENSION See Figures 30 and 31. 1. Stop the engine before setting the chain tension. Make sure the guide bar screw is loosened to finger tight, turn the chain tensioner clockwise to tension the chain. Refer to “Assembling the Bar and Chain” earlier in this manual for additional information. A cold chain is correctly tensioned when there[...]

26 CHAIN MAINTENANCE See Figures 32 and 33. Fig. 34 Fig. 33 CHECK FOR WEAR OR DAMAGE Use only low-kickback chain on this saw . This fast- cutting chain will provide kickback reduction when properly maintained. For smooth and fast cutting, chain needs to be main- tained properly . The chain requires sharpening when the wood chips are small and powde[...]

27 W ARNING: Improper chain sharpening increases the potential of kickback. 5. Put a few firm strokes on every tooth. File all left hand cutters in one direction. Then move to the other side and file the right hand cutters in the opposite direction. Occasionally remove filings from the file with a wire brush. TOP PLATE FILING ANGLE See Figure 36. ?[...]

28 Use a Flat File and a Depth Gauge Jointer to lower all gauges uniformly . Depth gauge jointers are available in .020 in. to .035 in. (0.5 mm to 0.9 mm). Use a .025 in. (0.6 mm) depth gauge jointer . After lowering each depth gauge, restore original shape by rounding the front. Be careful not to damage adjoining drive links with the edge of the f[...]
