3. Fit the other end of the saw chain around the sprocket, then attach the guide bar to the chain saw body, aligning the hole on the guide bar with the pin on the chain saw body. Adjusting saw chain tension CAUTION: Do not tighten the saw chain too much. Excessively high tension of saw chain may cause breakage of saw chain and wear of the guide bar. CAUTION: A chain which is too loose can jump off the bar and it may cause an injury accident. The saw chain may become loose after many hours of use.
4. Keep holding the guide bar lightly and tighten the sprocket cover. After refilling, hold the chain saw away from the tree. Start it and wait until lubrication on saw chain is adequate. For chain blade 90PX and 91PX: Make sure that the saw chain does not loose at the lower side. For chain blade 25AP: Make sure that the gap between the center of the lower side of the guide bar and the saw chain is approximately 1 mm to 2 mm. 5. Tighten the retaining nut to secure the sprocket cover.
Pruning trees Bring the chain saw body into contact with the branch to be cut before switching on. Otherwise it may cause the guide bar to wobble, resulting in injury to operator. Saw the wood to be cut by just moving it down by using the weight of the chain saw. If you try to cut off thick branches from the bottom, the branch may close in and pinch the saw chain in the cut. If you try to cut off thick branches from the top without a shallow undercut, the branch may splinter.
Sharpening the saw chain 30 Sharpen the saw chain when: • Mealy sawdust is produced when damp wood is cut; • The chain penetrates the wood with difficulty, even when heavy pressure is applied; • The cutting edge is obviously damaged; • The saw pulls to the left or right in the wood. (caused by uneven sharpening of the saw chain or damage to one side only) Sharpen the saw chain frequently but a little each time. Two or three strokes with a file are usually sufficient for routine resharpening.
Cleaning the sprocket cover 1 Chips and saw dust will accumulate inside of the sprocket cover. Remove the sprocket cover and saw chain from the tool then clean the chips and saw dust. 30 1/5 ► 1. File holder — After sharpening the chain, check the height of the depth gauge using the chain gauge tool (optional accessory). Cleaning the oil discharge hole Small dust or particles may be built up in the oil discharge hole during operation.
Replacing the sprocket CAUTION: A worn sprocket will damage a new saw chain. Have the sprocket replaced in this case. Before fitting a new saw chain, check the condition of the sprocket. 2 1 ► 1.
