Give special attention to logs under stress to prevent the bar and chain from pinching. OVERBUCKING See Figure 29. Begin on the top side of the log with the bottom of the saw against the log; exert light pressure downward. Note that the saw will tend to pull away from you. UNDERBUCKING See Figure 30. Begin on the under side of the log with the top of the saw against the log; exert light pressure upward. During underbucking, the saw will tend to push back at you. Be prepared for this reaction and hold the saw firmly to maintain control. OPERATION LOG SUPPORTED AT ONE END LOAD FINISHING CUT 1ST CUT 1/3 DIA LOG SUPPORTED AT BOTH ENDS 1ST CUT 1/3 DIA LOAD FINISHING CUT Fig. 28 OVERBUCKING Fig. 29 UNDERBUCKING Fig. 30 LIMBING AND PRUNING See Figures 31 - 32. n Work slowly, keeping both hands on the saw with a firm grip. Maintain secure footing and balance. ¦n Keep the tree between you and the chain while limbing. n Do not cut from a ladder. This is extremely dangerous. Leave this operation for professionals. ¦n Do not cut above chest height. A saw held higher than chest height is difficult to control against kickback. WARNING: Never climb into a tree to limb or prune. Do not stand on ladders, platforms, rooftops, a log, or in any position which can cause you to lose your balance or control of the saw. ¦n When pruning trees it is important not to make the flush cut next to the main limb or trunk until you have cut off the limb further out to reduce the weight. This prevents stripping the bark from the main member. • Underbuck the branch 1/3 through for your first cut. • Overbuck the branch to drop it. • Finish by cutting smoothly and neatly against the main member so the bark will grow back to seal the wound. WARNING: If the limbs to be pruned are above chest height, hire a professional to perform the pruning. CUTTING SPRINGPOLES See Figure 33. A springpole is any log, branch, rooted stump, or sapling which is bent under tension by other wood so that it springs back if the wood holding it is cut or removed. On a fallen tree, a rooted stump has a high potential of springing back to the upright position during the bucking cut to separate the log from the stump. Watch out for springpoles — they are dangerous. WARNING: Springpoles are dangerous and could strike the operator, causing the operator to lose control of the chain saw. This could result in severe or fatal injury to the operator. OPERATION SECOND CUT LOAD FIRST CUT 1/3 DIAMETER FINISHING CUT Fig. 31 CUT LIMBS ONE AT A TIME AND LEAVE SUPPORT LIMBS UNDER TREE UNTIL LOG IS CUT Fig. 32 SPRINGPOLE Fig. 33 MAINTENANCE WARNING: Make sure the on/stop switch is in the STOP “ ” position and the chain has stopped before performing any maintenance on the saw. Failure to do so may result in serious personal injuries. WARNING: Muffler surfaces are very hot during and after operation of the chain saw; keep all body parts away from the muffler. Serious burns may occur if contact is made with the muffler. WARNING: When servicing, use only identical Homelite replacement parts. Use of any other parts may create a hazard or cause product damage. WARNING: Aways wear eye protection with side shields marked to comply with ANSI Z87.1, along with hearing and head protection. Failure to do so could result in objects being thrown into your eyes and other possible serious injuries. GENERAL MAINTENANCE Avoid using solvents when cleaning plastic parts. Most plastics are susceptible to damage from various types of commercial solvents and may be damaged by their use. Use clean cloths to remove dirt, dust, lubricant, grease, etc. WARNING: Do not at any time let brake fluids, gasoline, petroleum-based products, penetrating oils, etc., come in contact with plastic parts. Chemicals can damage, weaken or destroy plastic which may result in serious personal injury. LUBRICATION All of the bearings in this product are lubricated with a sufficient amount of high grade lubricant for the life of the unit under normal operating conditions. Therefore, no further lubrication is required. RUN POSITION Fig. 34 Fig. 35 SPROCKET CLUTCH COVER Fig. 36 REPLACING THE GUIDE BAR AND CHAIN See Figures 34 - 43. DANGER: Never start the engine before installing the guide bar, chain, clutch cover, and clutch drum. Without all these parts in place, the clutch can fly off or explode, exposing the user to possible serious injury. WARNING: To avoid serious personal injury, read and understand all the safety instructions in this section. n Always place the switch in the STOP “” position before you work on the saw. n Make sure the chain brake is not set by pulling the chain brake lever/hand guard towards the front handle to the run position. NOTE: When replacing the guide bar and chain, always use the specified bar and chain listed in the Bar and Chain Combinations section later in this manual. n Wear gloves when handling the chain and bar. These components are sharp and may contain burrs. n Press in on the clutch cover loc...
