Numbers preceding the descriptions correspond with the num- bers on preceding page to help you locate the safety feature. 1 LOW KICKBACK SAW CHAIN helps significantly reduce kickback, or the intensity of kickback, due to specially designed depth gauges and guard links. 2 GUIDE BAR Reduced kickback guide bar reduces the inten- sity of kickback. 3 SPARK ARRESTER SCREEN tetains carbon and other flammable particles over 0.023 inches (0.6mm) in size from engine exhaust flow. Compliance with local, state and feder- al laws and/or regulations governing the use of a spark arrester screen is the user's responsibility. See Safety Precautions for additional information. 4 CHAIN BRAKE* LEVER / HAND GUARD protects the operator's left hand in the event it slips off the front handle while saw is running. 4 CHAIN BRAKE" is a safety feature designed to reduce the possibility of injury due to kickback by stopping a moving saw chain in miliseconds. It is activated by the CHAIN BRAKE® lever. 7 STOP SWITCH immediately stops the engine when tripped. Stop switch must be pushed to ON position to start or restart engine. 8 SAFETY TRIGGER prevents accidental acceleration of the engine. Throtile trigger (21) cannot be squeezed unless the safety latch is depressed. 23 CHAIN CATCHER reduces the danger of injury in the event saw chain breaks or derails during operation. The chain catcher is designed to intercept a whipping chain.

WARNING Kickback may occur when the nose or tip of the guide bar touches an object, or when the wood closes in and pinch- es the saw chain in the cut. If bar tip makes contact with something it may cause a lighining-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.

Do not overreach or cut above shoulder height.

6. Follow manufacturers sharpening and maintenance

instructions for the saw chain.

7. Only use replacement bars and chains specified by

the manufacturer or the equivalent. NOTE: Low-kickback saw chain is chain that has met the kickback performance requirements of ANSI B175.1-2000 (American National Standard for Power Tools Gasoline- Powered Chain Saws Safety Requirements) when tested on the representative sample of chain saws below 3.8 c.i.d. specified in ANSI B175.1-2000.

2-2. OTHER SAFETY PRECAUTIONS

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 one- handed operation. À chain saw is intended for two- handed 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.

Use caution when handling fuel. Move the chain saw at least 9.1m (30 feet) from the fueling point before starting the engine. 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. DO NOT start cutting until you have a clear work area, secure footing, and a planned retreat path from the falling tree. Keep all parts of your body away from the saw chain when the engine is running. Before you start the engine, make sure that the saw chain is not contacting anything. Carry the chain saw with the engine stopped, the guide bar and saw chain to the rear, and the muffler away from your body. 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 throtile control trigger is released. Shut off the engine before setting the chain saw down. 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. When cutting a limb that is under tension, be alert for springback so that you will not be struck when the ten- sion in the wood fibers is released. Keep the handles dry, clean, and free of oil or fuel mix- ture. Operate the chain saw only in well-ventilated areas. DO NOT operate a chain saw in a tree unless you have been specifically trained to do so. 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. When transporting your chain saw, use the appropri- ate guide bar scabbard. DO NOT operate your chain saw near or around flam- mable liquids or gases whether in or out of doors. An explosion and/or fire may result. USE THE RIGHT TOOL: Cut wood only. Do not use the chain saw for purposes for which it was not intend- ed. For example, do not use the chain saw for cutting plastic, masonry, or non-building materials. Do not attempt to add fuel or lubricating oil to saw while engine is running. NOTE: These safety precautions are intended primarily for the consumer or occasional user. When using a chain saw for logging purposes, refer to the Code of Federal Regulations, Section 1910.226(5); 2.5.1, of American National Standard Safety Requirements for Pulpwood Logging, ANSI 03.1-1978; and relevant state safety codes. These models are classified according to CAN/ CSA- Z62.1-03 as a Class 1C saw. They are intended for infre- quent use by homeowners, cottagers, and campers, and for such general applications as clearing, pruning, cutting fire- wood, 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. All models covered in this manual employ an anti- vibration feature for increased comfort and safety.

1. Fatigue causes carelessness. Be more cautious

before rest periods and towards the end of your shift.

2. Personal protective clothing required by your safety

organizations, government regulations, or your employer should be used. At all times when using a chain saw, snug-fitting clothing, protective eye wear, safety footwear, and hand, leg, and hearing protection should be worn.

8. Before refueling, servicing, or transporting your chain

saw, switch off the engine. To help prevent fire, restart your chain saw at least 9.1m (30ft) from the fuelling area.

4. When a chain saw is being used, a fire extinguisher

should be available.

5. When felling, keep at least 2 tree lengths away from

your fellow workers.

6. Plan your work, ensuring an obstacle-free work area

and, in the case of felling, at least one escape path from the falling tree.

7. Follow the instructions in your operators manual for

starting the chain saw and control the chain saw with a firm grip on both handles when it is in operation. Keep handies dry, clean, and free of oil.

8. When transporting your chain saw, use the appropri-

ate transportation covers, which should be available for the guide bar and saw chain.

9. Never operate a chain saw that is damaged or improp-

erly adjusted or that is not completely and securely assembled. Be sure that the saw chain stops moving when the power control system trigger is released. Never adjust the guide bar or saw chain when the engine is operating.

10. Beware of carbon monoxide poisoning. Operate the

chain saw in well-ventilated areas only.

11. Do not attempt a pruning or limbing operation in a

standing tree unless specifically trained to do so.

12. Guard against kickback. Kickback is the upward

motion of the guide bar that occurs when the saw chain, at the nose of the guide bar, contacts an object. Kickback can lead to dangerous loss of control of the chain saw.

13. A chain saw is intended for two-handed use. Serious

injury to the operator, helpers, and/or bystanders can result from one-handed operation.

14. See section 2-5, 2-6 for symbol definitions, page 5.

15. When carrying a chain saw with the engine running,

engage the chain brake.

16. Allow your chain saw to cool before refueling, and do

17. Keep other persons or animals a safe distance away

from a running chain saw or the area where a tree is being felled.

18. Use extreme caution when cutting small brush and

saplings because slender material can catch the saw chain and be whipped toward you.

19. When cutting a limb that is under tension or compres-

sion, be alert for springback.

20. This gas-powered saw is classified according to CAN/

CSA-Z62.1-03 as a Class 1C saw. It is intended for infrequent use by homeowners, cottagers, and campers, and for such general applications as clear- ing, pruning, cutting firewood, etc. lt is not intended for prolonged use. Prolonged periods of operation can cause circulatory problems in the users hands due to vibration. For such use, it may be appropriate to use a saw having an anti-vibration feature.

2-4. MORE ABOUT KICKBACK

WARNING DANGER! BEWARE OF KICKBACK! Kickback can lead to dangerous loss of control of the chain saw and result in serious or fatal injury to the saw operator or to anyone standing close by. Always be alert. Rotational kickback and pinch-kickback are major chain saw opera- tional dangers and the leading cause of most accidents. BEWARE OF: ROTATIONAL KICKBACK (Figure 2-4A) A = Kickback path B = Kickback reaction zone

REACTIONS (Figure 2-4B) A = Pull B = Solid objects C = Push 2-4B KICKBACK may occur when the NOSE or TIP of the guide bar touches an object, or when wood closes in and pinch- es the saw chain in the cut. Tip contact in some cases may cause a lighining-fast reverse reaction, kicking the guide bar up and back toward the operator. PINCHING the saw chain along the BOTTOM of the guide bar may PULL the saw forward away from the operator. PINCHING the saw chain along the TOP of the guide bar may PUSH the guide bar rapidly back toward the operator. Any of these reactions may cause you to lose control of the saw, which could result in serious personal injury. WARNING The engine exhaust from this product contains chemi- cals known to the State of California to cause cancer, birth defects, or other reproductive harm.

2-5. KICKBACK SAFETY LABELS

Your McCulloch Chain Saw is provided with a safety label located on the chain brake lever. This label, along with the safety instructions on these pages, should be carefully read before attempting to operate this unit.

1. Combination wrench-screwdriver (contained in your

user's kit or in lid of carry case).

2. Heavy duty work gloves (user supplied).

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. WARNINGO DO NOT start saw engine until unit is properly prepared. 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 assem- ble, operate and maintain your saw.

3-3. GUIDE BAR / SAW CHAIN / CLUTCH

COVER INSTALLATION WARNING Always wear protective gloves when handling chain. TO INSTALL GUIDE BAR: CAUTION® To ensure the bar and chain receive oil, ONLY USE THE ORIGINAL STYLE BAR with the oil passage hole (A) as illustrated above (Figure 3-3A).

1. Make sure the CHAIN BRAKE® lever is pulled back

into the DISENGAGED position (Figure 3-3B)

2. Remove the bar retaining nuts (B). Remove clutch

cover (C) by pulling straight out, some force may be required. (Figure 3-3C) NOTE: Discard the two plastic washers. They are only used for shipping the chain saw.

8. Using a screwdriver or the wrench supplied in the

user's kit or in the upper half of the carrying case. Turn the adjustment screw (D) COUNTERCLOCKWISE until the TANG (E) (projecting prong) is to the end of its travel (Figure 3-3D).

TO INSTALL SAW CHAIN: WARNING Always wear heavy duty gloves when handling saw chain or making saw chain adjustments.

1. Spread chain out in a loop with cutting edges (A)

pointing CLOCKWISE around loop (Figure 3-3F).

2. Slip the chain around the sprocket (B) behind the

clutch (C). Make sure the links fit between the sprock- et teeth (Figure 3-8G).

8. Guide the drive links into the groove (D) and around

the end of the bar (Figure 3-3G). NOTE: The saw chain may droop slightly on the lower part of bar. This is normal.

4. Pull guide bar forward until chain is snug. Ensure all

drive links are in the bar groove.

5. Install the clutch cover making sure the tang is posi-

tioned in the lower hole in the guide bar. Make sure the chain does not slip off of the bar. Install the bar retaining nuts hand tight and follow tension adjust- ment instructions in Section 3-4. NOTE: The guide bar retaining nuts are installed only hand tight at this point because saw chain adjusiment is required. Follow instructions in Section 3-4, Saw Chain Tension Adjustment. NOTE:Open the right side yellow plastic cover and remove built-up wood and gunk. NOTE:Must both lube the tip and fill the oiler. 3-3G

3-4. SAW CHAIN TENSION ADJUSTMENT

Proper tension of saw chain is extremely important and must be checked before starting, as well as during any cut- ting operation. Taking the time to make needed adjustments to the saw chain will result in improved cutting performance and pro- longed chain life. WARNING Always wear heavy duty gloves when handling saw chain or making saw chain adjustments. 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 (Figure 3-4A).

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: lf 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 bar retaining nuts so it is 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 uppermost position and tighten the bar retaining nut securely.

3 - ASSEMBLY INSTRUCTIONS

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. CAUTION® If saw chain is TOO LOOSE or TOO TIGHIT, the sprocket, bar, chain, and crankshaft bearings will wear more rapidly. Study Figure 3-4B for information concerning correct cold tension (A), correct warm tension (B), and as a guide for when saw chain needs adjustment (C). 3-4B

3-5. 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, operators hand strikes the lever. When the brake is actuated, chain movement stops abruptly. WARNING The purpose of the CHAIN BRAKE® is to reduce the possi- bility 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. To Test CHAIN BRAKE*:

1. The CHAIN BRAKE® is DISENGAGED (chain can

move) when BRAKE LEVER IS PULLED BACK AND LOCKED. Be sure the chain break latch is in the on position. (Figure 3-5A).

2. The CHAIN BRAKE® is ENGAGED (chain is stopped)

when brake lever is in forward position and the chain brake latch is in the off position. You should not be able to move chain (Figure 3-5B). 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 an Authorized Service Center for repair. 3-5A 3-5B

4-1. FUEL Use regular grade unleaded gasoline mixed with Genuine McCulloch 40:1 2-cycle engine oil for best results. Use mix- ing ratios in Section 4-3. lw] Never use straight gasoline in your unit. This will cause permanent engine damage and void the manufactur- er's warranty for that product. Never use a fuel mixture that has been stored for over 90 days. [W) If 2-cycle lubricant other than Genuine McCulloch Lubricant is to be used, it must be a premium grade oil for 2-cycle air cooled engines mixed at a 40:1 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 manufaciurer's engine warran- ty for that occurrence.

Mix fuel with Genuine McCulloch brand 2 cycle oil in an approved container. Use mixing table for correct ratio of fuel to oil. Shake container to ensure thorough mix. [W) Lack of lubrication voids engine warranty.

4-3.FUEL AND LUBRICATION SYMBOLS

Gasoline and Oil Mix 40:1 Oil Only

Some conventional gasolines are being blended with oxy- genates such as alcohol or an ether compound to meet clean air standards. Your McCulloch engine is designed to operate on any gasoline intended for automotive use including oxygenated gasolines.

4-5.CHAIN AND BAR LUBRICATION

Always refill the chain oil tank each time the fuel tank is refilled. We recommend using Genuine McCulloch Chain, Bar and Sprocket Oil, which contains additives to reduce friction and wear and to assist in the prevention of pitch for- mation on the bar and chain.

diately activate the CHAIN BRAKE® lever (C) (Figure 5-5A). WARNING Activate the CHAIN BRAKE: slowly and deliberately. Keep the chain from touching anything; don't let the saw tip for- ward.

6. Chain should stop abruptly. When it does, immediately

release the throtile trigger. WARNING If chain does not stop, turn engine off and take your unit to the nearest Authorized Service Center for service.

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 evi- denced 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.

5-7. AUTOMATIC OILER

Your chain saw is equipped with an automatic clutch driv- en 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 approxi- mately the same time as the fuel supply runs out. 6-1.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 noich cuts. Notch cuts determine the direction the tree will fall. FELLING A TREE: WARNING A retreat path (A) should be planned and cleared as nec- essary before cuts are started. The retreat path should extend back and diagonally to the rear of the expected line of fall, as illustrated in Figure 6-1A. 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. NOTE: Direction of fall (B) is controlled by the notching cut. Before any cuis are made, consider the location of larger branches and natural lean of the tree to determine the way the tree will fall. 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 any cuts.

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. 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)

(Figure 6-1B). 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 guide bar from binding in the felling cut if you have mis- judged the falling direction. Make sure no bystanders have entered the range of the falling tree before you push it over. WARNING Before making the final cut, always recheck the area for bystanders, animals or obstacles. FELLING CUT:

1. Use wooden or plastic wedges (G) to prevent binding

the bar or chain (H) in the cut. Wedges also control felling (Figure 6-1C).

2. When diameter of wood being cut is greater than the

bar length, make 2 cuts as shown (Figure 6-1D). WARNING As the felling cut gets close to the hinge, the tree should begin to fall. When tree begins to fall, remove saw from cut, stop engine, put chain saw down, and leave area along retreat path (Figure 6-1A).

6-2. LIMBING 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 (Figure 6-2A). Branches under tension should be cut from the bottom up to avoid binding the chain saw. WARNING Never cut tree limbs while standing on tree trunk. 6-2A 6-3. 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 (over-

buck), being careful to avoid cutting into the ground (Figure 6-3A).

2. Log supported on 1 end: First, cut from bottom (under-

buck) 1/3 diameter of log to avoid splintering. Second, cut from above (overbuck) to meet first cut and avoid pinching (Figure 6-3B).

8. Log supported on both ends: First, overbuck 1/3 diam-

eter of log to avoid splintering. Second, underbuck to meet first cut and avoid pinching (Figure 6-3C). 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 sup- porting logs. Be sure the log being cut is securely support- ed. 6-3A

For personal safety and ease of cutting, the correct position for vertical bucking is essential (Figure 6-4A). 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. CAUTION While the saw is cutting, be sure the chain and bar are being properly lubricated. All chain saw service, other than items listed here in your user manual maintenance instructions, should be performed by your nearest Authorized Service Center.

7-1.PREVENTIVE MAINTENANCE

7-6.CARBURETOR ADJUSTMENT

The carburetor was pre-set at the factory for optimum per- formance. |f further adjustments are necessary, please take your unit to the nearest Authorized Service Center listed in the Yellow Pages.

7-7.STORING À CHAIN SAW

CAUTIONO Never store a chain saw for longer than 30 days without performing the following procedures. Storing a chain saw for longer than 30 days requires stor- age maintenance. Unless the storage instructions are fol- lowed, fuel remaining in the carburetor will evaporate, leav- ing gum-like deposits. This could lead to difficult starting and result in costly repairs.

1. Remove the fuel tank cap slowly to release any pres-

sure 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 combus-

tion chamber. Pull starter rope slowly several times to coat internal components. Replace spark plug (Figure 7-7À). NOTE: Store the unit in a dry place and away from possi- ble sources of ignition such as a furnace, gas hot water heater, gas dryer, etc.

2. Pull starter rope briskly to clear excess oil from com-

8. Clean and gap spark plug or install a new spark plug

4. Prepare unit for operation.

5. Fill fuel tank with proper fuel / oil mixture. See Fuel

and Lubrication Section.

Frequent lubrication of the guide bar (railed bar which sup- ports and carries the saw chain) sprocket tip is required. Proper maintenance of the guide bar, as explained in this section, is essential to keep your saw in good working con- dition. SPROCKET TIP LUBRICATION: CAUTION®O 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. 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 lubri- cation. 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: WARNING Wear heavy duty work gloves when handling the bar and chain. 1... Move the STOP switch down. NOTE: It is not necessary to remove the saw chain to lubri- cate the guide bar sprocket tip. Lubrication can be done on the job.

into the lubrication hole and inject grease until it appears at outside edge of sprocket tip (Figure 8-1A).

4. Rotate saw chain by hand. Repeat lubrication proce-

dure until the entire sprocket tip has been greased. 8-1A GUIDE BAR MAINTENANCE: Most guide bar problems can be prevented merely by keep- ing 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 mainte- nance procedures are recommended. BAR WEAR - Turn guide bar frequently at regular intervals (for example, after 5 hours of use), to ensure even wear on top and bottom of bar. BAR GROOVES - Bar grooves (or rails which support and carry the chain) should be cleaned if saw has been used heavily or if saw chain appears dirty. Rails should always be cleaned every time saw chain is removed. OIL PASSAGES - Oil passages on the bar should be cleaned to ensure proper lubrication of the bar and chain during operation. NOTE: The condition of the oil passages can be easily checked. If the passages are clear, the chain will automati- cally give off a spray of oil within seconds of starting the saw. Your saw is equipped with an automatic oiler system.

8-2. 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 À 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 length- en quickly. WARNING Never have more than 3 links removed from a loop of chain. This could cause damage to the sprocket. CHAIN LUBRICATION: Always make sure the automatic oiler system is working properly. Keep the oil tank filled with Genuine McCulloch 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 efficien- cy, 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 cut- ters 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 Authorized Service Center. If you feel comfortable sharpen- ing your own saw chain, special tools are available from the nearest Authorized Service Center.
