1. OPERATOR’S MANUAL – Included with unit. Read before operation and keep for future reference to learn proper, safe operating techniques. 2. FRONT HAND GUARD – Guard between the front handle and the saw chain for protecting the hand from injuries and aiding in control of the chain saw if the hand slips off the handle. This guard is used to activate the chain brake which is to stop the saw chain rotation. 3. REAR HANDLE (FOR THE RIGHT HAND) – Support handle located towards the rear of the engine housing. 4. THROTTLE TRIGGER LOCKOUT – A safety lever which must be depressed before the throttle trigger can be activated in order to prevent the accidental operation of the throttle trigger. 5. REAR HAND GUARD – Extension on the lower part of the rear handle for protecting the hand from the chain if it breaks or degrooves. 6. THROTTLE TRIGGER – Device activated by the operator’s finger, for controlling the engine speed. 7. CHOKE CONTROL KNOB – Device for enriching the fuel/air mixture in the carburettor to aid cold starting.
13. CHAIN – Chain, serving as a cutting tool. 14. CYLINDER COVER – The cooling air flow grill. It covers the cylinder, spark plug, silencer and air cleaner. 15. FRONT HANDLE (FOR THE LEFT HAND) – Support handle located at the front of the engine housing. 16. OIL TANK CAP – For closing the oil tank. 17. STARTER HANDLE – The grip of the starter, for starting the engine. 18. FUEL TANK CAP – For closing the fuel tank. 19. IGNITION SWITCH – Device for connecting and disconnecting the ignition system and thus allowing the engine to be started or stopped. 20. AIR CLEANER COVER – Covers air filter. 21. CLEANER COVER KNOB – Device for installing the air cleaner cover. 22. GUIDE BAR COVER – Remove device for covering the guide bar and saw chain during transport and other times when the chain saw is not in use
8. CLUTCH COVER – Protective cover to the guide bar, saw chain, clutch and sprocket when the chain saw in use. 9. CHAIN TENSION ADJUSTER – This is device to adjust chain tension. 10. CHAIN CATCHER – A projection designed to reduce the risk of the operator’s right hand from being hit by a chain which has broken or derailed from the guide bar during cutting. 11. SPIKED BUMPER – Devise, fitted in front of the guide bar mounting point, acting as a pivot when in contact with a tree or log. 12. GUIDE BAR – The part that supports and guide the saw chain.

GENERAL CUTTING INSTRUCTIONS (CONTINUED) Start the engine, see that is running properly. Squeeze the trigger to open the throttle wide open, then start the cut. It is not necessary to press down hard to make the saw cut. If the chain is properly sharpened, the cutting should be relatively effortless. Pushing the saw too hard will slow the engine and cutting will actually be more difficult. Some material may adversely affect the housing of your chain saw. (Example: palm tree acid, fertilizer etc.) To avoid housing deterioration carefully remove all packed saw dust around clutch and guide bar FELLING A TREE area and wash with water.
The felling cut is made on the side opposite the notch. Make the felling cut placing spiked bumper 2.5 cm to 5cm above the bottom of the notch and stop cutting at approximately 1/10 of diameter to the inner edge of the notch (See figure C) in order to leave the uncut portion of the wood as a hinge. Do not try to cut through to the notch with the felling cut. The remaining wood between the notch cut and felling cut will act as a hinge when the tree falls, guiding it in the desired direction.

SHARPENING (CONTINUED)
• Drive link serves to remove sawdust from the groove of the guide bar. • When setting of the chain is finished, soak it in oil and wash away filings completely before using. • When chain has been filed on the bar, supply sufficient oil to it, and rotate the chain slowly to wash away the filings before using again. • If the chain saw is operated with filings clogged in the groove, the saw chain and the guide bar will be damaged prematurely. • If the saw chain becomes soiled with resin for instance, clean it with kerosene and soak it in oil. STORAGE
h. Remove the spark plug and pour 1/2 tablespoon of fresh, clean, two-stroke engine oil into the cylinder through the spark plug hole. • Place a clean cloth over the spark plug hole. • Pull the recoil starter handle 2 or 3 times to distribute the oil inside the engine. • Observe the piston location through the spark plug hole. • Pull the recoil starter handle slowly until the piston reaches the top of its travel and leave it there. i. Install the spark plug (do not connect ignition cable). j. Cover the chain and the guide bar with the guide bar cover before putting them in storage.
