Chain Saw Nomenclature LEFT SIDE Front handle v Rear handle Trigger switch / RIGHT SIDE Oil cap Guide bar nose \ I Guide bar mounting pad Sprocket Bar Tip Guard -An attachment that may be provided on the end of the guide bar to prevent the chain at the end of the guide bar from contacting the wood. Bucking -The process of cross cutting a felled tree or log into lengths. Chain Brake -A device used to stop the chain saw. Chain Saw Powerhead -A chain saw without the saw chain and guide bar. Clutch -A mechanism for connecting and disconnecting a driven member to and from a rotating source of power. Drive Sprocket or Sprocket -The toothed part that drives the saw chain. Felling -The process of cutting down a tree. Felling Back Cut -The final cut in a tree felling operation made on the opposite side of the tree from the notching undercut. Front Handle -The support handle located at or toward the front of the chain saw. Front Handle Guard -A structural barrier between the front handle of a chain saw and the guide bar, typically located close to the hand position on the front handle and sometimes employed as an activating lever for a chain brake. Guide Bar -A solid railed structure that supports and guides the saw chain. Kickback -The backward or upward motion, or both of the guide bar occurring when the saw chain near the nose of the top area of the guide bar contacts any object such as a log or branch, or when the wood closes inand pinches the saw chain in the cut. Kickback, Pinch -The rapid pushback of the saw which can occur when the wood closes in and pinches the moving saw chain in the cut along the top of the guide bar. Kickback, Rotational -The rapid upward and backward motion of the saw which can occur when the moving saw chain near the upper portion of the tip of the guide bar contacts an object, such as a log or branch. Low-Kickback Chain -A chain that complies with the kickback performance requirements of ANSI B175.1 when tested on a representative sample of chain saws. Normal Cutting Position -Those positions assumed in performing the bucking and felling cuts. Notching Undercut -A notch cut in a tree that directs the tree's fall. Oiler Control -A system for oiling the guide bar and saw chain. Rear Handle -The support handle located at or toward the rear of the saw. Reduced Kickback Guide Bar -A guide bar which has been demonstrated to reduce kickback significantly. Replacement Saw Chain -A chain that complies with the kickback performance requirements of ANSI 6175.1 when tested with specific chain saws. It may not meet the ANSI performance requirements when used with other saws. Saw Chain -A loop of chain having cutting teeth, that cut the wood, and that is driven by the motor and is supported by the guide bar. Spiked Bumper (Spike) -The pointed tooth or teeth for use when felling or bucking to pivot the saw and maintain position while sawing. Switch -A device that when operated will complete or interrupt an electrical power circuit to the motor of the chain saw. Lock-Off Button -A movable stop that prevents the unintentional operation of the switch until manually actuated. Installing saw chain and guide bar CAUTION : Always be sure that the tool is switched off and unplugged before installing saw chain and guide bar Use the socket wrench to loosen the hex bolt holding the chain cover. Remove the chain cover. 1 Fig. 2 Fit one end of the chain over the sprocket and the other over the end of the guide bar. Notice that the cutters must be in the direction of the arrow in Fig. 3 and 4. Keep the chain in the guide bar grooves. Install the guide bar so that the lower hole in the guide bar is just over the adjusting pin. Install the chain cover and tighten the hex bolt only tight enough to hold the guide bar temporarily. Adjusting saw chain tension CAUTION : Always be sure that the tool is switched off and unplugged before adjusting chain tension. Grasp the chain in the middle of the guide bar and lift up. The gap between the side link of the chain and the guide bar should be about 3 mm to 4 mm (1/8" -5/32"). Fig. 5 If the gap is not about 3mm to 4mm (1/8" -5/32"), adjust the chain tension. Use a screwdriver to turn the chain tension adjusting screw clockwise for more tension, or counterclockwise for less tension. When adjusting the chain tension, lift the end of the guide bar slightly. Fig. 6 After adjusting the chain tension, use the...
