Page 14 PREPARING FOR CUTTING PROPER GRIP ON HANDLES See Figures 16 and 17. Refer to “S pecific Safety Rules – Safety Apparel” earlier in this manual for appropriate safety equipment. Wear non-slip gloves for maximum grip and protection. Hold the saw firmly with both hands.
Page 15 STOP STOP BASIC OPERATING/CUTTING PROCEDURES Practice cutting a few small logs using the following technique to get the “feel” of using your saw before you begin a major sawing operation. 1. T ake the proper stance in front of the wood with the saw idling.
Page 16 STOP 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 If the engine starts, runs, and accelerates but will not idle, turn the idle speed screw “ T ” clockwise to increase idle speed.

Pick your escape route (or routes in case the in- tended route is blocked).
Page 18 4. Make the backcut level and horizontal, and at a mini- mum of 2 inches (5 cm) above the horizontal cut of the notch. 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).
Page 19 REMOVING BUTTRESS ROOTS See Figure 28. 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 20 BUCKING LOGS UNDER STRESS Make the first bucking cut 1/3 of the way through the log and finish with a 2/3 cut on the opposite side. As you cut the log, it will tend to bend. The saw can become pinched or hung in the log if you make the first cut deeper than 1/3 of the diameter of the log.
Page 21 LIMBING AND PRUNING See Figure 33. 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 36 through 44. 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.
Page 23 6. Lay out the saw chain in a loop and straighten any kinks. The cutters should face in the direction of chain rotation. If they face backwards, turn the loop over . 7. Place the chain drive links into the bar groove as shown. 8. Position the chain so there is a loop at the back of the bar.
Page 24 11. Replace the outer guide bar plate ensuring that the bar pin groove is at the bottom with the upper and lower edges angled away from the guide bar. 12. Replace the clutch cover and bar mounting nuts. 13. Tighten the bar mounting nuts finger tight only.
Page 25 ADJUSTING THE CHAIN TENSION See Figures 45, 46, and 47. W ARNING: Never touch or adjust the chain while the motor is running. The saw chain is very sharp. Always wear protective gloves when performing maintenance on the chain. 1. Stop the engine before setting the chain tension.

Be careful to file all cutters to the specified angles and to the same length, as fast cutting can only be obtained when all cutters are uniform.
Page 27 Fig. 52 Fig. 53 LEFT HAND CUTTERS RIGHT HAND CUTTERS Fig. 54 CAUTION: A dull or improperly sharpened chain can cause excessive engine speed during cutting which may result in severe engine damage. W ARNING: Improper chain sharpening increases the potential of kickback.
Page 28 TOP PLATE FILING ANGLE See Figure 55. CORRECT 30° - file holders are marked with guide marks to align file properly to produce correct top plate angle. LESS THAN 30° – for cross cutting. MORE THAN 30° – feathered edge dulls quickly.
Page 29 Fig. 60 LUBRICA TING HOLE MAINTAINING THE GUIDE BAR See Figure 60. CA UTION: Make sure the chain has stopped before you do any work on the saw. Every week of use, reverse the guide bar on the saw to distribute the wear for maximum bar life. The bar should be cleaned every day of use and checked for wear and damage.
Page 30 STOP STOP MOUNTING THE SAFE-T-TIP® NOSE GUARD See Figures 61 and 62. 1. Mount the SAFE-T-TIP on the bar nose. 2. Fit the locking rivet or tab in the recessed hole in the guide bar. 3. Tighten the screw with your finger. 4. From the finger tight position, tighten the screw an additional 3/4 of a turn using a wrench.
Page 31 STOP STOP STOP STOP CLEANING THE ENGINE See Figures 67 and 68. Clean the cylinder fins and flywheel fins with compressed air or a brush periodically.
Page 32 CLEANING THE SPARK ARRESTING MUFFLER See Figure 71. The muffler is equipped with a sp ark arrestor screen. A faulty spark arrestor screen can create a fire hazard. Through normal use the screen can become dirty and should be inspected weekly and cleaned as required.
