Page 10 W ARNING: Always shut off engine before fueling. Never add fuel to a machine with a running or hot engine. Move at least 30 ft. (9 m) from refueling site before starting the engine. DO NOT SMOKE! Failure to heed this warning can result in possible personal injury.
Page 11 ADDING OIL See Figures 9 and 10. Use HOMELITE Bar and Chain Oil. It is designed for chains and chain oilers, and is formulated to perform over a wide temperature range with no dilution required. Chain saw should use approximately one tank of oil per tank of fuel.
Page 12 STARTING THE ENGINE See Figures 13 through 19. W ARNING: Keep your body to the left of the chain line. Never straddle the saw or chain, or lean over past the chain line. 1. Place the chain saw on level ground and ensure that no objects or obstructions are in the immediate vicinity that could come in contact with the bar and chain.
Page 13 7 . When the temperature is above 50° F, pull the STARTER GRIP until the engine attempts to start, but no more than 3 times. When the temperature is below 50° F, pull the STARTER GRIP until the engine attempts to start, but no more than 5 times.
Page 14 PREPARING FOR CUTTING PROPER GRIP ON HANDLES See Figure 22 and 23. Ref er to “Specific Saf ety Rules – Safety Apparel” earlier in this manual for appropriate safety equipment. ■ ■ ■ ■ ■ W ear non-slip gloves f or maximum grip and protection.
Page 15 BASIC OPERATING/CUTTING PROCEDURES Practice cutting a f ew small logs using the f ollowing 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 w ood with the saw idling.
Page 16 W ARNING: Weather conditions and altitude may affect carburetion. Do not allow bystanders close to the chain saw while adjusting the carburetor. ADJUSTING IDLE SPEED See Figure 28. ■ ■ ■ ■ ■ If the engine starts, runs, and accelerates but will not idle, turn the idle speed screw “ T ” clockwise to increase idle speed.
Page 17 PROPER PROCEDURE FOR TREE FELLING See Figures 30, 31, 32, and 33. 1. Pick your escape route (or routes in case the in- tended route is blocked). Clear the immediate area around the tree and make sure there are no obstruc- tions in your planned path of retreat.
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 34. A b uttress root is a large root e xtending 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 See Figure 37. Make the first b ucking cut 1/3 of the wa y 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 39. ■ 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 41 through 51. 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. La y out the saw chain in a loop and straighten an y kinks. The cutters should face in the direction of chain rotation. If the y face bac kwards , turn the loop over . 7. Place the chain drive links into the bar groove as shown in figure 46.
Page 24 14. Remove all slack from the chain using the chain tensioning screw. Place a slotted screwdriver in the slot and turn clockwise until the chain seats snugly against the bar with the drive links in the bar groove. CHAIN TENSIONING SCREW MAINTENANCE Fig.
Page 25 ADJUSTING THE CHAIN TENSION See Figures 52, 53, and 54 . 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.
Page 26 CUTTING CORNER SIDE PLATE DEPTH GAUGE TOE GULLET HEEL RIVET HOLE TOP PLATE Fig. 57 ■ Raker (depth gauge) clearance. 1. Too low increases the potential for kickback.
Page 27 Fig. 59 Fig. 60 LEFT HAND CUTTERS RIGHT HAND CUTTERS Fig. 61 CA UTION: 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 62. ■ 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. 66 MAINTAINING THE GUIDE BAR See Figure 67. 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 ev er y day of use and chec ked f or wear and damage.
Page 30 CA UTION: Never run the engine without the air filter, serious damage could result. Make sure the air filter is correctly placed in the air filter cover before reassembly. ■ Clean the pre-filter every 25 tanks of fuel or sooner, if required.
Page 31 CLEANING THE ENGINE See Figures 74 and 75. Clean the cylinder fins and flywheel fins with compressed air or a brush periodically. Dangerous overheating of the engine may occur due to impurities on the cylinder. W ARNING Never run the saw without all the parts, including the drivecase cover and starter housing, securely in place.
Page 32 CLEANING THE SPARK ARRESTING MUFFLER See Figure 78. The muffler is equipped with a spark 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.
Page 33 PROBLEM POSSIBLE CAUSE SOLUTION Engine will not start. (Make sure Ignition Switch is in start position “I”.) Engine starts but will not accelerate properly. Engine starts but will not run properly at high speed . Engine does not reach full speed and/or emits excessive smoke.
Page 34 PROBLEM POSSIBLE CAUSE SOLUTION Engine starts, runs, and accelerates but will not idle. Chain turns at idle. Bar and chain running hot and smoking. Engine starts and runs, but chain is not rotating. Carburetor requires adjustment. Carburetor requires adjustment.
