4. After chain tension is correct, tighten guide bar nuts firmly. If not, guide bar will move and loosen chain tension. This will increase the risk of kickback. This can also damage saw. Note: A new chain will stretch. Check new chain after first few minutes of operation. Allow chain to cool down. Readjust chain tension. OPERATING CHAIN SAW WARNING: Read and understand this owner’s manual before operating this saw. Make certain you read and understand all Safety Warnings. Improper use of this chain saw can cause severe injury or death from fire, electrical shock, or body contact with moving chain, or falling wood. Guide Bar Correct Tension Guide Bar Gap Incorrect Tension Guide Bar Nuts OWNER’S MANUAL Figure 8 - Pressing Squeeze Bulb on Oil Cap to Oil Chain OPERATING CHAIN SAW Continued OILING CHAIN Always check oil level before using saw. To oil chain, press squeeze bulb on oil cap. Do not attempt to operate the oiler while cutting with the saw. Oil will feed onto guide bar and chain. Press squeeze bulb on oil cap at least once before each cut. Check oil level often by looking at oil sight level hole. Oil sight level hole is on left side of saw, between front handle and front hand guard. 6. When starting a cut, place moving chain against wood. Hold saw firmly in place to avoid possible bouncing or skating (sideways movement) of saw. 7. Guide saw using light pressure. Do not force saw. The motor will overload and can burn out. 8. Remove saw from a cut with saw running at full speed. Stop saw by releasing trigger. Do not use the chain brake. Make sure chain has stopped before setting saw down. 9. Practice until you can maintain a steady, even cutting rate. Front Hand Guard Switch Trimming a tree is the process of cutting limbs from a living tree. Make sure your footing is firm. Keep feet apart. Divide your weight evenly on both feet. Follow directions below to trim a tree. 1. Make first cut 15 centimeters (six inches) from tree trunk on underside of limb. Use top of guide bar to make this cut. Cut 1/3 through diameter of limb (see Figure 10). 2. Move five to ten centimeters (two to four inches) farther out on limb. Make second cut from above limb. Continue cut until you cut limb off. 3. Make third cut as close to tree trunk as possible on underside of limb stub. Use top of guide bar to make this cut. Cut 1/3 through diameter of stub. 4. Make fourth cut directly above third cut. Cut down to meet third cut. This will remove limb stub. CAUTION: Seek professional help if facing conditions beyond your ability. CUTTING WITH THE CHAIN SAW 1. Connect saw to extension cord. Connect extension cord to power supply. 2. Make sure section of log to be cut is not laying on ground. This will keep chain from touching ground as it cuts through log. Touching ground with moving chain will dull chain. 3. Use both hands to grip saw. Always use left hand to grip front handle and right hand to grip rear handle. Use firm grip. Thumbs and fingers must wrap around saw handles (see Figure 9). 4. Make sure your footing is firm. Keep feet apart. Divide your weight evenly on both feet. Stand slightly to left side of saw. This keeps your body from being in direct line with chain. 5. When ready to make a cut, press in switch lockout with right thumb and squeeze trigger (see Figure 9). This will turn saw on. Releasing trigger will turn saw off. Make sure saw is running at full speed before starting a cut.
