GENERAL SAFETY RULES
GB
WARNING! When using gas tools, basic safety precautions, including the following, should always be followed to
reduce the risk of serious personal injury and/or damage to the unit.
Read all these instructions before operating this product and save these instructions.
1. DO NOT operate a chain saw with one hand! Serious injury to the operator, helpers, bystanders, or any combination of these persons may result from one­handed operation. A chain saw is intended for two­handed use.
2. DO NOT operate a chain saw when you are fatigued.
3. Use safety footwear, snug-fitting clothing, protective gloves, and eye, hearing and head protection devices.
4. Use caution when handling fuel. Move the chain saw at least 10 feet (3m) from the fueling point before starting the engine.
5. DO NOT allow other persons to be near when start­ing or cutting with the chain saw. Keep bystanders and animals out of the work area.
6. DO NOT start cutting until you have a clear work area, secure footing, and a planned retreat path from the falling tree.
7. Keep all parts of your body away from the saw chain when the engine is running.
8. Before you start the engine, make sure that the saw chain is not contacting anything.
9. Carry the chain saw with the engine stopped, the guide bar and saw chain to the rear, and the muffler away from your body.
10. DO NOT operate a chain saw that is damaged, improperly adjusted, or not completely and securely assembled. Be sure that the saw chain stops moving when the throttle control trigger is released.
11. Shut off the engine before setting the chain saw down.
12. Use extreme caution when cutting small size brush and saplings because slender material may catch the saw chain and be whipped toward you or pull you off balance.
13. When cutting a limb that is under tension, be alert for springback so that you will not be struck when the tension in the wood fibers is released.
14. Keep the handles dry, clean, and free of oil or fuel mixture.
15. Operate the chain saw only in well-ventilated areas.
16. DO NOT operate a chain saw in a tree unless you have been specifically trained to do so.
17. All chain saw service, other than the items listed in the user manual safety and maintenance instructions, should be performed by competent chain saw service personnel.
18. When transporting your chain saw, use the appropri­ate guide bar scabbard (when supplied).
19. DO NOT operate your chain saw near or around flammable liquids or gases whether in or out of doors. An explosion and/or fire may result.
20. Do not tank fuel, oil or lubrication when the engine of chain saw is running.
21. USE THE RIGHT TOOL: Cut wood only. Do not use the chain saw for purposes for which it was not intended. For example, do not use the chain saw for cutting plastic, masonry, or nonbuilding materials.
NOTE: This appendix is intended primarily for the con­sumer or occasional user. These models are intended for infrequent use by homeowners, cottagers, and campers, and for such general applications as clearing, pruning, cutting firewood, etc. They are not intended for prolonged use. If the intended use involves prolonged periods of operation, this may cause circulatory problems in the user’s hands due to vibration. It may be appropriate to use a saw having an anti-vibration feature such as the models covered in this manual with the suffix Anti-Vibration.
Kickback may occur when the nose or tip of the guide bar touches an object, or when the wood closes in and pinch­es the saw chain in the cut. If the bar tip contacts, it may cause a lightning-fast reverse reaction, kicking the guide bar up and back towards the operator. Pinching the saw chain along the top of the guide bar may push the guide bar rapidly back towards the operator. Either of these reactions may cause you to lose control of the saw, which could result in serious personal injury. Do not rely exclu­sively upon the safety devices built into your saw. As a chain saw user, you should take several steps to keep your cutting jobs free from accident or injury.
1. With a basic understanding of kickback, you can reduce or eliminate the element of surprise. Sudden surprise contributes to accidents.
2. Keep a good firm grip on the saw with both hands, the right hand on the rear handle, and the left hand on the front handle, when the engine is running. Use a firm grip with thumbs and fingers encircling the chain saw handles. A firm grip will help you reduce kickback and maintain control of the saw. Don’t let go.
3. Make sure that the area in which you are cutting is free from obstructions. Do not let the nose of the guide bar contact a log, branch, or any other obstruc­tion which could be hit while you are operating the saw.
4. Cut at high engine speeds.
5. Do not overreach or cut above shoulder height.
6. Follow manufacturer’s sharpening and maintenance instructions for the saw chain.
7. Only use replacement bars and chains specified by the manufacturer or the equivalent.

• TOOLS FOR ASSEMBLY
You will need these tools to assemble your chain saw:
1. Combination wrench-screwdriver (contained in your user’s kit).
2. Heavy duty work gloves (user supplied).
• ASSEMBLY REQUIREMENTS
Your new chain saw will require adjustment of chain, filling the fuel tank with correct fuel mixture and filling the oil tank with lubricating oil before the unit is ready for operation. Read the entire user manual before attempting to operate your unit. Pay particular attention to all safety precautions.
Your user manual is both a reference guide and hand­book provided to furnish you with general information to assemble, operate and maintain your saw.
• GUIDE BAR / SAW CHAIN / CLUTCH COVER INSTALLATION
TO INSTALL GUIDE BAR:
To ensure the bar and chain receive oil, ONLY USE THE ORIGINAL STYLE BAR with the oil passage hole (A) as illustrated below (Fig. 3A).
1. Make sure the Chain brake lever is pulled back into the DISENGAGED position (Fig. 3B)
2. Remove the 2 bar retaining nuts (B). Loosen the 2 screws at the rear of the clutch cover (C). Remove the cover (Fig. 3C).
3. Using a screwdriver, run the adjustment screw (D) COUNTERCLOCKWISE until the TANG (E) (pro­jecting prong) is to the end of its travel toward the clutch drum and sprocket (Fig. 3D).
4. Place the slotted end of the guide bar over the 2 bar bolts (F). Position the bar so that the adjustment TANG fits into the lower hole (G) on the guide bar (Fig. 3E).
TO INSTALL SAW CHAIN:
1. Spread chain out in a loop with cutting edges (A) pointing CLOCKWISE around loop (Fig. 4A).
2. Slip the chain around the sprocket (B) behind the clutch (C). Make sure the links fit between the sprocket teeth (Fig. 4B).
3. Guide the drive links into the groove (D) and around the end of the bar (Fig. 4B).
NOTE: The saw chain may droop slightly on the lower part of bar. This is normal.
4. Install the clutch cover and tighten the 2 screws. Make sure the chain does not slip off of the bar. Install the 2 nuts hand tight and follow tension adjustment instructions in Section SAW CHAIN
TENSION ADJUSTMENT.
NOTE: The guide bar retaining nuts are installed only
hand tight at this point because saw chain adjustment is required. Follow instructions in Section SAW CHAIN
TENSION ADJUSTMENT.
• SAW CHAIN TENSION ADJUSTMENT
Proper tension of saw chain is extremely important and must be checked before starting, as well as during any cutting operation.
Taking the time to make needed adjustments to the saw chain will result in improved cutting performance and prolonged chain life.
TO ADJUST SAW CHAIN:
1. Hold nose of guide bar up and turn adjustment screw (D) CLOCKWISE to increase chain tension. Turning screw COUNTERCLOCKWISE will decrease amount of tension on chain. Ensure the chain fits snugly all the way around the guide bar (Fig. 5).
2. After making adjustment, and while still holding nose of bar in the uppermost position, tighten the bar retaining nuts securely. Chain has proper tension when it has a snug fit all around and can be pulled around by gloved hand.
NOTE: If chain is difficult to rotate on guide bar or if it binds, too much tension has been applied. This requires minor adjustment as follows:
A. Loosen the 2 bar retaining nuts so they are finger
tight. Decrease tension by turning the bar adjustment screw COUNTERCLOCKWISE slowly. Move chain back and forth on bar. Continue to adjust until chain rotates freely, but fits snugly. Increase tension by turning bar adjustment screw CLOCKWISE.
B. When saw chain has proper tension, hold nose of
bar in the uppermost position and tighten the 2 bar retaining nuts securely.
ASSEMBLY INSTRUCTIONS
WARNING:
DO NOT start saw engine until
unit is properly prepared.
WARNING: Always wear protective gloves when handling chain.

WARNING: Always wear heavy duty gloves when handling saw chain or making saw chain adjustments.
• CHAIN BRAKE MECHANICAL TEST
Your chain saw is equipped with a Chain brake that reduces possibility of injury due to kickback. The brake is activated if pressure is applied against brake lever when, as in the event of kickback, operator’s hand strikes the lever. When the brake is actuated, chain movement stops abruptly.
TO TEST CHAIN BRAKE:
1. The Chain brake is DISENGAGED (chain can move) when BRAKE LEVER IS PULLED BACK AND LOCKED (Fig. 7A).
2. The Chain brake is ENGAGED (chain is stopped) when brake lever is in forward position. You should not be able to move chain (Fig. 7B).
NOTE: The brake lever should snap into both positions. If strong resistance is felt, or lever does not move into either position, do not use your saw. Take it immediately to a professional Service Center for repair.
• FUEL
Use regular grade unleaded gasoline mixed with 2-cycle engine oil in 25:1 ratio for best results. Use mixing ratios in Section FUEL MIXING TABLE.
• MIXING FUEL
Mix fuel with Talon brand 2 cycle oil in an approved container. Use mixing table for correct ratio of fuel to oil. Shake container to ensure thorough mix.
• FUEL AND LUBRICATION
• FUEL MIXING TABLE
• RECOMMENDED FUELS
Some conventional gasolines are being blended with oxygenates such as alcohol or an ether compound to meet clean air standards. Your Talon engine is designed to operate satisfactorily on any gasoline intended for automotive use including oxygenated gasolines.
• CHAIN AND BAR LUBRICATION
Always refill the chain oil tank each time the fuel tank is refilled. We recommend using Talon Chain, Bar and Sprocket Oil, which contains additives to reduce friction and wear and to assist in the prevention of pitch formation on the bar and chain.
Fig. 6

CAUTION: A new saw chain stretches, requiring adjustment after as few as 5 cuts. This is normal with a new chain, and the interval between future adjustments will lengthen quickly.
Fig. 5
B
CAUTION: If saw chain is TOO LOOSE or TOO TIGHT, the sprocket, bar, chain, and crankshaft bearings will wear more rapidly. Study Fig. 6 for information concerning correct cold tension (A), correct warm tension (B), and as a guide for when saw chain needs adjustment (C).
WARNING: The purpose of the chain brake is to reduce the possibility of injury due to kickback; however, it cannot provide the intended measure of protection if the saw is operated carelessly. Always test the chain brake before using your saw and periodically while on the job.

FUEL AND LUBRICATION
WARNING: Never use straight gasoline in your
unit. This will cause permanent engine damage and void the manufacturer’s warranty for that product. Never use a fuel mixture that has been stored for over 90 days.
WARNING: If 2-cycle lubricant other than Talon Custom Lubricant is to be used, it must be a pre­mium grade oil for 2-cycle air cooled engines mixed at a 25:1 ratio. Do not use any 2-cycle oil product with a recommended mixing ratio of 100:1. If insufficient lubrication is the cause of engine damage, it voids the manufacturer’s engine warranty for that occurrence.
WARNING:
Lack of lubrication voids engine
warranty.

• SAW CHAIN / BAR LUBRICATION
Adequate lubrication of the saw chain is essential at all times to minimize friction with the guide bar. Never starve the bar and chain of oil. Running the saw with too little oil will decrease cutting efficiency, shorten saw chain life, cause rapid dulling of chain, and cause excessive wear of bar from overheating. Too little oil is evidenced by smoke, bar discoloration or pitch build-up.
NOTE: Saw chain stretches during use, particularly when it is new, and it will occasionally be necessary to adjust and tighten it. New chain will require adjustment after about 5 minutes of operation.
• AUTOMATIC OILER
Your chain saw is equipped with an automatic gear driven oiler system. The oiler automatically delivers the proper amount of oil to the bar and chain. As the engine speed increases, so does the oil flow to the bar pad. There is no flow adjustment. The oil reservoir will run out at approximately the same time as the fuel supply runs out.
• FELLING
Felling is the term for cutting down a tree. Small trees up to 6-7 inches (15-18cm) in diameter are usually cut in a single cut. Larger trees require notch cuts. Notch cuts determine the direction the tree will fall.
FELLING A TREE:
NOTE: Direction of fall (B) is controlled by the notching cut. Before any cuts are made, consider the location of larger branches and natural lean of the tree to determine the way the tree will fall.
GENERAL GUIDELINES FOR FELLING TREES:
Normally felling consists of 2 main cutting operations, notching (C) and making the felling cut (D). Start making the upper notch cut (C) on the side of the tree facing the felling direction (E). Be sure you don t make the lower cut too deep into the trunk. The notch (C) should be deep enough to create a hinge (F) of sufficient width and strength. The notch should be wide enough to direct the fall of the tree for as long as possible.
Never saw completely through the trunk. Always leave a hinge. The hinge guides the tree. If the trunk is completely cut through, control over the felling direction is lost.
Insert a wedge or felling lever in the cut well before the tree becomes unstable and starts to move. This will prevent the guidebar from binding in the felling cut if you have misjudged the falling direction. Make sure no bystanders have entered the range of the falling tree before you push it over.
FELLING CUT:
1. Use wooden or plastic wedges (A) to prevent binding the bar or chain (B) in the cut. Wedges also control felling (Fig. 14A).
2. When diameter of wood being cut is greater than the bar length, make 2 cuts as shown (Fig. 14B).
GENERAL CUTTING INSTRUCTIONS
WARNING: A retreat path (A) should be planned
and cleared as necessary before cuts are started. The retreat path should extend back and diagonally to the rear of the expected line of fall, as illustrated in Fig. 12.
CAUTION: If felling a tree on sloping ground, the chain saw operator should keep on the uphill side of the terrain, as the tree is likely to roll or slide downhill after it is felled.
Fig. 12
B
A
WARNING: Do not cut down a tree during high or changing winds or if there is a danger to prop­erty. Consult a tree professional. Do not cut down a tree if there is a danger of striking utility wires; notify the utility company before making
WARNING:
Never walk in front of a tree that has been notched. Make the felling cut (D) from the other side of the tree and 1.5 - 2.0 inches (3-5 cm) above the edge of the notch (C) (Fig. 13)
Fig. 13
WARNING: Before making the final cut, always recheck the area for bystanders, animals or obstacles.
Fig. 14B
Fig. 14A

Limbing a tree is the process of removing the branches from a fallen tree. Do not remove supporting limbs (A) until after the log is bucked (cut) into lengths (Fig. 15). Branches under tension should be cut from the bottom up to avoid binding the chain saw.
• BUCKING
Bucking is cutting a fallen log into lengths. Make sure you have a good footing and stand uphill of the log when cutting on sloping ground. If possible, the log should be supported so that the end to be cut off is not resting on the ground. If the log is supported at both ends and you must cut in the middle, make a downward cut halfway through the log and then make the undercut. This will prevent the log from pinching the bar and chain. Be careful that the chain does not cut into the ground when bucking as this causes rapid dulling of the chain. When bucking on a slope, always stand on the uphill side.
1. Log supported along entire length: Cut from top (overbuck), being careful to avoid cutting into the ground (Fig. 16A).
2. Log supported on 1 end: First, cut from bottom (underbuck) 1/3 diameter of log to avoid splintering. Second, cut from above (overbuck) to meet first cut and avoid pinching (Fig. 16B).
3. Log supported on both ends: First, overbuck 1/3 diameter of log to avoid splintering. Second, underbuck to meet first cut and avoid pinching (Fig. 16C).
NOTE: The best way to hold a log while bucking is to use a sawhorse. When this is not possible, the log should be raised and supported by the limb stumps or by using supporting logs. Be sure the log being cut is securely supported.
• BUCKING USING A SAWHORSE
For personal safety and ease of cutting, the correct position for vertical bucking is essential (Fig. 17).
VERTICAL CUTTING:
A. Hold the saw firmly with both hands and keep the
saw to the right of your body while cutting.
B. Keep the left arm as straight as possible. C. Keep weight on both feet.
All chain saw service, other than items listed here in your user manual maintenance instructions, should be performed by a professional.
• PREVENTIVE MAINTENANCE
A good preventive maintenance program of regular inspection and care will increase life and improve performance of your Talon chain saw. This maintenance checklist is a guide for such a program. Cleaning, adjustment, and parts replacement may be required, under certain conditions, at more frequent intervals than those indicated.
• AIR FILTER
TO CLEAN AIR FILTER:
1. Remove the top cover (A) by loosening the cover retaining screws. Cover will lift off.
2. Lift the air filter (B) out of air-box (C) (Fig. 18).
3. Clean air filter. Wash filter in clean, warm, soapy water. Rinse in clear, cool water. Air dry completely.
NOTE: It is advisable to have a supply of spare filters.
4. Install air filter. Install engine / air filter cover. Make sure cover fits properly. Tighten the cover retaining screws securely.
WARNING:
Never cut tree limbs while
standing on tree trunk.

FUEL AND LUBRICATION. Install fuel cap.
• SPARK ARRESTER SCREEN (Fig. 20A)
NOTE: A clogged spark arrester screen will dramatically
reduce engine performance.
1. Remove the 2 bar retaining nuts (A) and loosen the 2 screws (B) that secure the chain brake cover (Fig. 20A).
2. Remove the chain brake cover. Remove the 3 screws that hold the muffler to the cylinder. The muffler will lift off after retaining screws are removed (Figure 7-4B).
3. Separate muffler halves (C). Remove the metal baffles (D) and spacer tubes (E).
4. Discard the used spark arrester screen and replace it with a new one (F) (Fig. 20B).
5. Reassemble the muffler components and install the muffler to the cylinder. Tighten screws securely.
• SPARK PLUG NOTE: For efficient operation of saw engine, spark plug
must be kept clean and properly gapped.
1. Push STOP switch down.
2. Disconnect the wire connector (A) from the spark plug (B) by pulling and twisting at the same time (Fig. 21).
3. Remove spark plug with spark plug socket wrench. DO NOT USE ANY OTHER TOOL.
4. Reinstall a new spark plug, gapped at .635mm.
• CARBURETOR ADJUSTMENT
The carburetor was pre-set at the factory for optimum performance. If further adjustments are necessary, please take your unit to the nearest professional.
• STORING A CHAIN SAW
Storing a chain saw for longer than 30 days requires storage maintenance. Unless the storage instructions are followed, fuel remaining in the carburetor will evapo­rate, leaving gum-like deposits. This could lead to diffi­cult starting and result in costly repairs.
1. Remove the fuel tank cap slowly to release any pressure in tank. Carefully drain the fuel tank.
2. Start the engine and let it run until the unit stops to remove fuel from carburetor.
3. Allow the engine to cool (approx. 5 minutes).
4. Using a spark plug wrench, remove the spark plug.
5. Pour 1 teaspoon of clean 2-cycle oil into the combustion chamber. Pull starter rope slowly several times to coat internal components. Replace spark plug (Fig. 22).
NOTE: Store the unit in a dry place and away from possible sources of ignition such as a furnace, gas hot water heater, gas dryer, etc.

NOTE: The condition of the oil passages can be easily checked. If the passages are clear, the chain will automatically give off a spray of oil within seconds of starting the saw. Your saw is equipped with an automatic oiler system.
• CHAIN MAINTENANCE CHAIN TENSION:
Check the chain tension frequently and adjust as often as necessary to keep the chain snug on the bar, but loose enough to be pulled around by hand.
BREAKING IN A NEW SAW CHAIN:
A new chain and bar will need chain readjustment after as few as 5 cuts. This is normal during the break-in period, and the interval between future adjustments will begin to lengthen quickly.
CHAIN LUBRICATION:
Always make sure the automatic oiler system is working properly. Keep the oil tank filled with Talon Chain, Bar and Sprocket Oil. Adequate lubrication of the bar and chain during cutting operations is essential to minimize friction with the guide bar. Never starve the bar and chain of lubricating oil. Running the saw dry or with too little oil will decrease cutting efficiency, shorten saw chain life, cause rapid dulling of chain, and lead to excessive wear of bar from overheating. Too little oil is evidenced by smoke or bar discoloration.
CHAIN SHARPENING:
Chain sharpening requires special tools to ensure that cutters are sharpened at the correct angle and depth. For the inexperienced chain saw user, we recommend that the saw chain be professionally sharpened by the nearest professional Service Center. If you feel comfortable sharpening your own saw chain, special tools are available from the professional Service Center.

• REMOVING A UNIT FROM STORAGE
1. Remove spark plug.
2. Pull starter rope briskly to clear excess oil from com­bustion chamber.
3. Clean and gap spark plug or install a new spark plug with proper gap.
4. Prepare unit for operation.
5. Fill fuel tank with proper fuel / oil mixture. See FUEL AND LUBRICATION Section.
Lubrication of the sprocket tip is recommended after 10 hours of use or once a week, which ever occurs first. Always thoroughly clean guide bar sprocket tip before lubrication.
TOOLS FOR LUBRICATION:
The Lube Gun (optional) is recommended for applying grease to the guide bar sprocket tip. The Lube Gun is equipped with a needle nose tip which is necessary for the efficient application of grease to the sprocket tip.
TO LUBRICATE SPROCKET TIP:
1. Move the STOP switch down.
NOTE: It is not necessary to remove the saw chain to lubricate the guide bar sprocket tip. Lubrication can be done on the job.
2. Clean the guide bar sprocket tip.
3. Using the Lube Gun (optional), insert needle nose into the lubrication hole and inject grease until it appears at outside edge of sprocket tip (Fig .23).
4. Rotate saw chain by hand. Repeat lubrication proce­dure until the entire sprocket tip has been greased.
GUIDE BAR MAINTENANCE:
Most guide bar problems can be prevented merely by keeping the chain saw well maintained.
Insufficient guide bar lubrication and operating the saw with chain that is TOO TIGHT will contribute to rapid bar wear.
To help minimize bar wear, the following guide bar main­tenance procedures are recommended.
CHAIN SHARPENING - The pitch of the chain (Fig. 24) is 3/8” LoPro x .050”.
Sharpen the chain using protective gloves and a round file of ø3/16” (4.8mm).
Always sharpen the cutters only with outward strokes (Fig. 25) observing the values given in Fig. 24.
After sharpening, the cutting links must all have the same width and length.
After every 3-4 times the cutters have been sharpened you need to check the height of the depth gauges and, if necessary, lower them using a flat file and template, then round off the front corner. (Fig. 26)
GUIDE BAR - The bar should be reversed every 8 work­ing hours to ensure uniform wear.
Keep the bar groove and lubrication hole clean using a bar groove cleaner. (Fig. 27)
Check the bar rails frequently for wear and, if necessary, remove the burs and square-up the rails using the flat file. (Fig. 28)
BAR WEAR - Turn guide bar frequently at regular intervals (for example, after 8 hours of use), to ensure even wear on top and bottom of bar.
OIL PASSAGES - Oil passages on the bar should be cleaned to ensure proper lubrication of the bar and chain during operation.
CAUTION: The sprocket tip on your new saw has
been pre-lubricated at the factory. Failure to lubricate the guide bar sprocket tip as explained below will result in poor performance and seizure, voiding the manufacturer’s warranty.
WARNING: Wear heavy duty work gloves
when handling the bar and chain.
Fig. 23
WARNING: Always wear protective gloves dur-
ing maintenance operations. Do not carry out maintenance when the engine is hot.
Fig. 24
WARNING: A sharp chain produces well-
defined chips. When your chain starts to produce sawdust, it is time to sharpen.
Fig. 26Fig. 25
WARNING: Proper adjustment of the depth
gauge is as important as proper sharpening of the chain.
WARNING: Never mount a new chain on a
worn sprocket or self-aligning ring.
