Page 16 W ARNING: Weather conditions and altitude may affect carbure- tion. Do not allow bystanders close to the chain saw while adjusting the carburetor. ADJUSTING IDLE SPEED See Figure 26.

Pick your escape route (or routes in case the in- tended route is blocked).
Page 18 Note: Never cut through to the notch. Always leave a band of wood between the notch and back cut (approxi- mately 2 inches (5 cm) or 1/10 the diameter of the tree). This is called "hinge" or "hingewood". It controls the fall of the tree and prevents slipping or twisting or shoot- back of the tree off the stump.
Page 19 REMOVING BUTTRESS ROOTS See Figure 31. A buttress root is a large root extending from the trunk of the tree above the ground. Remove large buttress roots prior to felling. Make the horizontal cut into the buttress first, followed by the vertical cut.

Page 21 LIMBING AND PRUNING See Figure 36. Work slowly, keeping both hands on the saw with a firm grip. Maintain secure footing and balance. Keep the tree between you and the chain while limbing. Do not cut from a ladder, this is extremely dangerous.
Page 22 ASSEMBLING THE BAR AND CHAIN See Figures 38 through 48. D ANGER: Never start the engine before installing the guide bar, chain, drivecase cover, and clutch drum. Without all these parts in place, the clutch can fly off or explode exposing the user to possible serious injury.
