IDENTIFICATION OF SYMBOLS Starting Reminder Move ON/STOP switch to the ON position. Pull the starter rope sharply 5 times with your right hand. Slowly press primer bulb 6 times. Push the choke/fast idle lever in to the HALF CHOKE position. Pull choke/fast idle lever out to the full extent (to the FULL CHOKE position). Pull the starter rope sharply with your right hand until the engine starts. SAFETY RULES S Always use approved hearing protection.
S Make sure the chain will not make contact with any object while starting the engine. Never try to start the saw when the guide bar is in a cut. S Do not put pressure on the saw at the end of the cut. Applying pressure can cause you to lose control of the chain saw when the cut is completed and may cause serious personal injury. S Stop the engine before setting the saw down. S Do not operate a chain saw that is damaged, improperly adjusted, or not completely and securely assembled.
S Mix and pour fuel in an outdoor area on bare ground; store fuel in a cool, dry, well ventilated place; and use an approved, marked container for all fuel purposes. Wipe up all fuel spills before starting saw. S Move at least 10 feet (3 meters) from fueling site before starting engine. S Turn the engine off and let saw cool in a non-combustible area, not on dry leaves, straw, paper, etc. Slowly remove fuel cap and refuel unit.
Symmetrical Guide Bar Large Radius Tip Elbow locked S Low--Kickback Chain, designed with a contoured depth gauge and guard link which deflect kickback force and allow wood to gradually ride into the cutter. Thumb on underside of handlebar Low-Kickback Chain Contoured Depth Gauge Elongated Guard Link Deflects Kickback Force And Allows Wood To Gradually Ride Into Cutter S Keep a good, firm grip on the saw with both hands when the engine is running and don’t let go.
ASSEMBLY Protective gloves (not provided) should be worn during assembly. 4. Turn the adjusting screw by hand counterclockwise until the adjusting pin just touches the stop. This should allow the pin to be near the correct position. 5. Slide guide bar on bar bolts until guide bar stops against clutch drum sprocket. ATTACHING THE BUMPER SPIKE The bumper spike may be used as a pivot when making a cut. 1. Loosen and remove the bar nuts and the clutch cover from the saw. 2.
1. Loosen bar nuts until they are finger tight against the clutch cover. 2. Turn adjusting screw clockwise until chain solidly contacts bottom of guide bar rail. Clutch Cover Adjusting Screw Adjusting Pin Lower Hole 3. Using bar tool, roll chain around guide bar to ensure all links are in bar groove. 4. Lift up tip of guide bar to check for sag.

mixed with a good quality 2-cycle air-cooled engine oil designed to be mixed at a ratio of 40:1. A 40:1 ratio is obtained by mixing 0,125 liter of oil with 5 liters of unleaded gasoline. DO NOT USE automotive or boat oil. These oils will cause engine damage. When mixing fuel follow the instructions printed on the container. Always read and follow the safety rules relating to fuel before fueling your unit. NOTE: Do not cut material with the choke/fast idle lever at the FULL CHOKE position.
DIFFICULT STARTING (or starting a flooded engine) The engine may be flooded with too much fuel if it has not started after 10 pulls. Flooded engines can be cleared of excess fuel by pushing the choke/fast idle lever in completely (to the OFF CHOKE position) and then following the warm engine starting procedure listed above. Ensure the ON/ STOP switch is in the ON position. Starting could require pulling the starter rope handle many times depending on how badly the unit is flooded.
Natural conditions that can cause a tree to fall in a particular direction include: S The wind direction and speed. S The lean of the tree. The lean of a tree might not be apparent due to uneven or sloping terrain. Use a plumb or level to determine the direction of tree lean. S Weight and branches on one side. S Surrounding trees and obstacles. Look for decay and rot. If the trunk is rotted, it can snap and fall toward the operator. Make sure there is enough room for the tree to fall.
Using a support stand 2nd Cut Overcutting begins on the top side of the log with the saw against the log. When overcutting use light downward pressure. Overcutting 1st Cut Undercutting Undercutting involves cutting on the underside of the log with top of saw against the log. When undercutting use light upward pressure. Hold saw firmly and maintain control. The saw will tend to push back toward you. WARNING: Never turn saw upside down to undercut. The saw cannot be controlled in this position.
S Make your fist cut 1/3 of the way through the bottom of the limb. S Next make a 2nd cut all the way through the limb. Then cut a third overcut leaving a 3 to 5 cm collar from the trunk of the tree. Second cut Third cut Collar First cut Pruning technique SERVICE AND ADJUSTMENTS WARNING: Improper maintenance could result in serious engine damage or in serious injury. Cylinder Cover Air Filter Cover WARNING: Disconnect the spark plug before performing maintenance, except for carburetor adjustments.
excess heating or burring of the rails occurs. If replacement is necessary, use only the guide bar specified for your saw in the repair parts list or on the decal located on the chain saw. SPARK PLUG The spark plug should be replaced each year to ensure the engine starts easier and runs better. Ignition timing is fixed and nonadjustable. 1. Loosen 3 screws on cylinder cover. 2. Remove the cylinder cover. 3. Pull off the spark plug boot. 4. Remove spark plug from cylinder and discard. 5.
Too Much Hook Angle Squared Off Corner S Turn idle speed screw (T) clockwise to increase engine speed. S Turn idle speed screw (T) counterclockwise to decrease engine speed. STORAGE Wrong WARNING: Maintain the proper hook angle according to the manufacturer’s specifications for the chain you are using. Improper hook angle will increase the chance of kickback which can result in serious injury. 4. Check and lower depth gauges. File Depth Gauge Tool Depth Gauge S Place gauge tool on cutter.
