  • Page 11: Operation

    FUEL ANd REFUELING HANdLING THE FUEL SAFELy WARNING: Check for fuel leaks. If any are found, correct them before using the saw to prevent fire or burn injury.  Always handle fuel with care; it is highly flammable.  Always refuel outdoors and do not inhale fuel vapors.  Do not let gasoline or oil come in contact with skin.
  • Page 12 AddING bAR ANd CHAIN OIL See Figure . 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 13 STARTING THE ENGINE See Figures  - 11. Starting the product differs depending on whether the engine is cold or warm. WARNING: Keep your body to the left of the chain line. Never straddle the saw or chain, or lean over past the chain line.  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 14  Push choke lever to HALF choke position.  Pull starter grip until engine runs. NOTE: Allow the saw to run in this position 15-30 sec- onds, depending upon the temperature.  Push choke lever all the way in to the RUN position.  Squeeze and release the throttle trigger to return the engine to idle after a total run time of at least 30 sec- onds.
  • Page 15 AdJUSTING IdLE SPEEd See Figure 1.  If the engine starts, runs, and accelerates, but will not idle, turn the idle speed screw “T” clockwise to increase idle speed.  If the chain turns at idle, turn the idle speed screw “T” counterclockwise to reduce the idle RPM and stop the chain movement.
  • Page 16: Preparing For Cutting

    KICKbACK PRECAUTIONS See Figures 1 - 1. Rotational kickback occurs when the moving chain contacts an object at the Kickback Danger Zone of the guide bar. The result is a lightning-fast reverse reaction, which kicks the guide bar up and back towards the operator. This reaction can cause loss of control, which can result in serious injury.
  • Page 17 PROPER CUTTING STANCE See Figure 1.  Balance your weight with both feet on solid ground.  Keep left arm with elbow locked in a “straight arm” posi- tion to withstand any kickback force.  Keep your body to the left of the chain line.  Keep your thumb on underside of handlebar.
  • Page 18: Felling Trees

    FELLING TREES HAzARdOUS CONdITIONS WARNING: Do not fell trees during periods of high wind or heavy precipitation. Wait until the hazardous weather has ended. When felling a tree, it is important that you heed the following warnings to prevent possible serious injury.  Do not cut down trees having an extreme lean or large trees with rotten limbs, loose bark, or hollow trunks.
  • Page 19  On large diameter trees, stop the back cut before it is deep enough for the tree to either fall or settle back on the stump. Then insert soft wooden or plastic wedges into the cut so they do not touch the chain. Drive wedges in, little by little, to help jack the tree over.
  • Page 20 bUCKING WITH A WEdGE See Figure . If the wood diameter is large enough for you to insert a soft bucking wedge without touching the chain, you should use the wedge to hold the cut open to prevent pinching. NOTE: When bucking or felling with a wedge, you may need to remove the SAFE-T-TIP anti-kickback device to allow the bar to be drawn through the cut.
  • Page 21 UNdERbUCKING See Figure 0. Begin on the under side of the log with the top of the saw against the log; exert light pressure upward. During under- bucking, the saw will tend to push back at you. Be prepared for this reaction and hold the saw firmly to maintain control.
  • Page 22: Maintenance

    WARNING: When servicing, use only identical Homelite replacement parts. Use of any other parts may create a hazard or cause product damage. WARNING: Always wear safety goggles or safety glasses with side shields during power tool operation or when blowing dust.
  • Page 23  Lay out the new 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.  Place the chain drive links into the bar groove as shown.
  • Page 24: Adjusting The Chain Tension

     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.  Replace the clutch cover and bar mounting nuts.  Finger-tighten the bar mounting nuts. The bar must be free to move for tension adjustment.
  • Page 25  Retension the chain whenever the flats on the drive links hang out of the bar groove. NOTE: During normal saw operation, the temperature of the chain increases. The drive links of a correctly ten- sioned warm chain will hang approximately .050 in. out of the bar groove.
  • Page 26 SHARPENING THE CUTTERS See Figures  - . 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. WARNING: The saw chain is very sharp. Always wear protective gloves when performing maintenance to the chain to prevent serious personal injury.
  • Page 27 TOP PLATE FILING ANGLE See Figure .  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. SIdE PLATE ANGLE See Figure .
  • Page 28 MAINTAINING THE GUIdE bAR See Figure . CAUTION: 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 29 CLEANING THE AIR FILTER See Figures 1 - .  For access to the air filter and carburetor area, loosen the three screws holding the cylinder cover.  Activate chain brake.  Lift the front of the cylinder cover past chain brake lever.
  • Page 30: Adjusting The Carburetor

    AdJUSTING THE CARbURETOR See Figures  - . before adjusting the carburetor:  Use a brush or compressed air to clean the starter cover vents.  Clean the air filter. Refer to Cleaning the Air Filter in the Maintenance section of this manual.  Allow the engine to warm up prior to adjustment of engine idle speed.
  • Page 31 CLEANING THE ENGINE See Figures  - . 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. WARNING Never run the saw without all the parts, including the drivecase cover and starter housing, securely in place.
  • Page 32: Maintenance

    INSPECTING/CLEANING THE SPARK ARRESTOR SCREEN See Figure 1. 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. Always keep the muffler and spark arrestor on the saw in good condition.
