Stihl MS 150 C-E Instruction Manual - Page 19

special handle design (closely spaced handles), there is an increased risk of injury from loss of control. For this reason this special chain saw should be used only for work in a tree by persons trained in special cutting and working techniques. This type of chain saw is not designed for cutting work on the ground, such as felling and bucking. Because this chain saw is not intended for use on the ground, this manual does not contain instructions for felling or for limbing and bucking felled trees. For instructions on these techniques when using other STIHL chain saw models, see the instruction manuals for these saws or the STIHL Chain Saw Safety Manual, which is available free from your STIHL servicing dealer. Cutting Techniques 1 2 2 1 Logs under strain: 001BA152 KN 001BA151 KN Risk of pinching! Always start relieving cut (1) at compression side. Then make bucking cut (2) at tension side. If the saw pinches, stop the engine and remove it from the log. Only properly trained professionals should work in an area where the logs, limbs and roots are tangled. Working in "blow down" areas is extremely hazardous. Drag the logs into a clear area before cutting. Pull out exposed and cleared logs first. If conditions allow, work from a lift bucket. WARNING Be extremely cautious when cutting limbs under tension (spring poles). The limbs could spring back toward the operator and cause loss of control of the saw and severe or fatal injury to the operator. MAINTENANCE, REPAIR AND STORING Maintenance, replacement, or repair of the emission control devices and systems may be performed by any nonroad engine repair establishment or individual. However, if you make a warranty claim for a component which has not been serviced or maintained properly or if nonapproved replacement parts were used, STIHL may deny coverage. English WARNING Use only identical STIHL replacement parts for maintenance and repair. Use of non-STIHL parts may cause serious or fatal injury. Strictly follow the maintenance and repair instructions in the appropriate section of your instruction manual. Please refer to the maintenance chart in this manual. WARNING Always stop the engine and make sure that the cutting tool is stopped before doing any maintenance or repair work or cleaning the power tool. WARNING Do not attempt any maintenance or repair work not described in your instruction manual. Have such work performed by your STIHL servicing dealer only. For example, if improper tools are used to remove the flywheel or if an improper tool is used to hold the flywheel in order to remove the clutch, structural damage to the flywheel could occur and could subsequently cause the flywheel to burst. Wear gloves when handling or performing maintenance on saw chains. WARNING Use the specified spark plug and make sure it and the ignition lead are always clean and in good condition. Always press spark plug boot snugly onto spark plug terminal of the proper size. (Note: If terminal has detachable SAE adapter MS 150 TC 17
