4 SYMBOLS

In this manual and/or on the machine the following symbols are used:

5 SAFETY

 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. A chain saw is intended for two-handed use.

 DO NOT operate a chain saw when you are fatigued, under the influence of drugs, alcohol

or medication.

 Use safety footwear, snug-fitting clothing, protective gloves, and eye, hearing and head

protection devices.

POW64115 EN

 Use caution when handling fuel. To avoid fire, move the chain saw at least 10 feet (3m)

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 throttle 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 spring back so that you will not be

struck when the tension in the wood fibers is released.

 Keep the handles dry, clean, and free of oil or fuel mixture.  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 appropriate guide bar scabbard.  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.

 Do not fill fuel tank, oil tank or lubricate when the engine is running.  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 non-building materials.

 The first time user should have practical instruction in the use of chainsaw and the

protective equipment from an experienced operator.

 Do not attempt to hold the saw with one hand only. You cannot control reactive forces and

you may lose control of the saw, which can result in the skating or bouncing of the bar and chain along the limb or log.

 Never run the chainsaw indoors. Your chainsaw produces poisonous exhaust as soon as

the combustible engine is started, which may be colorless and odorless. To use this product can generate dust, mists and fumes containing chemicals known to cause reproductive harm. Be aware of harmful dust, mist (such as saw dust or oil mist from chain lubrication) and protect your self properly.

 Wear gloves and keep your hand warm. Prolonged use of chainsaws exposing the

operator to vibrations may produce white finger disease. In order to reduce the risk of white finger disease, please wear gloves and keep your hand warm. If any of the white finger symptoms appear, seek medical advice immediately.

 Drive in the spiked bumper of the chainsaw directly behind the intended hinge and pivot the

saw around this point. The spiked bumper rolls against the trunk.

 Only chain, guide bar and spark plug can be replaced by the user himself. Always make

sure you replace with correct material as stated in the specifications of the manual.

Rotational kickback A = kickback path B = kickback reaction zone

6 KICKBACK SAFETY PRECAUTIONS

KICKBACK may occur when the NOSE or TIP of the guide bar touches an object, or when wood closes in and pinches the saw chain in the cut. Tip contact in some cases may cause a lightning-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.  With a basic understanding of kickback, you can reduce or eliminate the element of

surprise. Sudden surprise contributes to accidents.

 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.

 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.

 Cut at high engine speeds.  Do not overreach or cut above shoulder height.  Follow manufacturer’s sharpening and maintenance instructions for the saw chain.  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.

WARNING: 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 operational dangers and the leading cause of most accidents.

Beware of:

To ensure the bar and chain receive oil, only use the original style bar with the oil passage hole (A) as illustrated above. (fig. 3a)

7 ASSEMBLY

Note : described actions below may vary slightly depending on model you purchased.

7.1 Tools for assembly

You will need these tools to assemble your chain saw:

 Combination wrench-screwdriver (contained in your user’s kit).  Heavy duty work gloves (user supplied).

7.2 Assembly requirements

Warning: do not start saw engine until unit is properly prepared.

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.

7.3 Guide bar / saw chain / clutch cover installation

Warning: always wear protective gloves when handling chain.

7.3.1 To install the guide bar

POW64115 EN

fig 3b

 Make sure the chain brake lever is pulled back into

the disengaged position(fig. 3b)

fig 3c

 Remove the bar retaining nut(s) (B). Remove the

chain brake cover (C) by pulling straight out, some force may be required. (fig. 3c).

fig

 Place the slotted end of the guide bar over the bar

bolt (F). Slide guide bar behind clutch drum (G) until the guide bar stops (fig. 3d).

fig

 Spread chain out in a loop with cutting edges

(1) pointing clockwise (fig. 4a).

fig 4b

 Slip the chain around the sprocket (B) behind the

clutch (C). Make sure the links fit between the sprocket teeth (fig. 4b).

 Guide the drive links into the groove (D) and

around the end of the bar (fig. 4b).

7.3.2 To install saw chain: Always wear heavy duty gloves when handling saw chain or making saw chain adjustments.

POW64115 EN

fig 5

 Hold nose of guide bar up and turn adjustment

screw (16) 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)

Note: the saw chain may droop slightly on the lower part of bar. This is normal.

 Pull guide bar forward until chain is snug. Ensure all drive links are in the bar groove.  Install the clutch cover making sure the tang is positioned in the lower hole in the guide bar.

Make sure the chain does not slip off of the bar. Install the bar retaining nut 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.

7.3.3 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.

Warning: always wear heavy duty gloves when handling saw chain or making saw chain adjustments.

7.3.4 To adjust saw chain:

 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:

 Loosen the 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.

 When saw chain has proper tension, hold nose of bar in the uppermost position and tighten

the 2 bar retaining nuts securely.

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 6

POW64115 EN

fig 7a

 The chain brake is disengaged (chain can move)

when brake lever is pulled back and locked. Be sure the chain brake latch is in the off position. (fig. 7a)

fig 7b

 The chain brake is engaged (chain is stopped) when

brake lever is in forward position and the chain brake latch is in the on position. You should not be able to move chain. (fig. 7b)

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).

7.3.5 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, operator’s hand strikes the lever. When the brake is actuated, chain movement stops abruptly.

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.

7.3.6 To test chain brake:

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.

8 FUEL AND LUBRICATION

8.1 Fuel

Use regular grade unleaded gasoline mixed with 25:1 custom 2-cycle engine oil for best results. Use mixing ratios in section fuel mixing table below.

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: 2-cycle lubricant 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.

8.2.2 Mixing ratio: 25 parts gasoline to 1 part lubricant

8.2.3 Recommended fuels Some conventional gasolines are being blended with oxygenates such as alcohol or an ether

compound to meet clean air standards. The engine is designed to operate satisfactorily on any gasoline intended for automotive use including oxygenated gasolines.

8.2.4 Chain and bar lubrication Always refill the chain oil tank each time the fuel tank is refilled. We recommend using our

replacement chain & bar. Always use good quality sprocket oil, which contains additives to reduce friction and wear and to assist in the prevention of pitch formation on the bar and chain

POW64115 EN

fig 10

 With your left hand, hold the front handle (B) [not

chain brake lever (C)] firmly (fig. 10).

 Squeeze the throttle trigger to 1/3 throttle, then

immediately activate the chain brake lever (C) (fig.

10).

9.6 Chain brake operational test

Test the chain brake periodically to ensure proper function. Perform a chain brake test prior to initial cutting, following extensive cutting, and definitely following any chain brake service.

Test chain brake as follows:

 Place saw on a clear, firm, flat surface.  Start engine.  Grasp the rear handle (A) with your right hand (fig. 10).

Warning: activate the chain brake slowly and deliberately. Keep the chain from touching anything; don t let the saw tip forward.

 Chain should stop abruptly. When it does, immediately release the throttle trigger.

Warning: if chain does not stop, turn engine off and take your unit to the nearest authorized service center for service.

 If chain brake functions properly, turn the engine off and return the chain brake to the

disengaged position.

9.7 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.

9.8 Automatic oiler

Your chain saw is equipped with an automatic clutch 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.

Do not adjust the chain lubrication system unless the motor has been turned off.

The chain lubrication system has been preset to medium oil flow at the factory. The flow can be adjusted if necessary.

POW64115 EN

fig 11a

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.

 To adjust the oil flow, turn the adjusting screw at the bottom

side of the housing (19)

 Turning it clockwise reduces the oil flow, while turning it

counterclockwise increases the oil.

9.9 General cutting instructions

9.9.1 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 notch cuts. Notch cuts determine the direction the tree will fall.

Felling a tree:

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. 11a

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.

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.

POW64115 EN

fig 11b

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. 11b)

fig11c

 Use wooden or plastic wedges (A) to prevent

binding the bar or chain (B) in the cut. Wedges also control felling (fig. 11c)

fig11d

 When diameter of wood being cut is greater than the bar

length, make 2 cuts as shown (fig. 11d).

Fig 12

Limbing a tree is the process of removing the branches from a fallen tree. Do not remove supporting limbs until after the log is bucked (cut) into lengths (Fig. 12). Branches under tension should be cut from the bottom up to avoid binding the chain saw.

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 misjudged 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:

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 (Fig. 11a).

9.9.2 Limbing

WARNING: Never cut tree limbs while standing on tree trunk.

POW64115 EN

Fig 13a

 Log supported along entire length: Cut from top

(overbuck), being careful to avoid cutting into the ground (Fig. 13a).

Fig 13b

 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. 13b).

Fig 13c

 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. 13c)

fig 14

For personal safety and ease of cutting, the correct position for vertical bucking is essential (fig. 14). Vertical cutting:  Hold the saw firmly with both hands and keep

the saw to the right of your body while cutting.

 Keep the left arm as straight as possible.  Keep weight on both feet.

9.9.3 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.

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.

9.9.4 Bucking using a sawhorse

Caution: while the saw is cutting, be sure the chain and bar are being properly lubricated.

11 CLEANING AND MAINTENANCE

11.1 Sprocket tip lubrication:

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.

Lubrication of the sprocket tip is recommended after 25 hours of use or once a week, which ever occurs first. Always thoroughly clean guide bar sprocket tip before lubrication.

POW64115 EN

fig 20

 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. 20).

 Rotate saw chain by hand. Repeat lubrication

procedure until the entire sprocket tip has been greased.

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.

 Press 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.

 Clean the guide bar sprocket tip.

11.2 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.

Warning: always wear protective gloves during maintenance operations. Do not carry out maintenance when the engine is hot.

11.3 Chain sharpening:

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.

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. For non-experienced users of the chain saw, we recommend to have the chain sharpened by a specialist in any authorized service.

Warning: when having wrong sharpened chain, there may occur a higher danger of kickback.

 To sharpen the saw chain, use the suitable sharpening tools:

 round chain file  file leading  chain measuring caliber.

These tools can be bought in any specialized stores.

fig 23

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 the flat file and template supplied optional, then round off the front corner. (Fig. 23)

 To gain well shaped sawdust particles, use sharp chain. If there appears wooden powder,

you must sharpen the saw chain.

Warning: all cutting teeth must be similarly long. Different length of the teeth can cause rough run of the chain or its rupture, as well.

 Minimum length of the teeth must be 4mm. If they are shorter, remove the saw chain.  Angles, which the teeth are under, must be followed.  To sharpen the chain basically, make 2 to 3 pulls of the file from the inside out.

Warning: after 3 to 4 of your sharpening of the cutting teeth, have the saw chain sharpened in any authorized service. They will sharpen the depth limiter as well, which provides the distance.

Chain sharpening The pitch of the chain (fig. 21) depends on the model.

Sharpen the chain using protective gloves and a round file of ø5/32” (4mm). Always sharpen the cutters only with outward strokes (fig.22) observing the values given in fig.

21. After sharpening, the cutting links must all have the same width and length.

Warning: a sharp chain produces well-defined chips. When your chain starts to produce sawdust, it is time to sharpen.

WARNING: Proper adjustment of the depth gauge is as important as proper sharpening of the chain.

11.4 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 (optional). (fig. 24) check the bar rails frequently for wear and, if necessary,

Warning: never mount a new chain on a worn sprocket or self-aligning ring.

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.

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.

11.5 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.

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 good quality 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.

12 TECHNICAL DATA

13 STORING A CHAIN SAW

Caution: 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 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.  Remove the fuel tank cap slowly to release any pressure in tank. Carefully drain the fuel

tank.

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.

Removing a unit from storage

 Remove spark plug.  Pull starter rope briskly to clear excess oil from combustion chamber.  Clean and gap spark plug or install a new spark plug with proper gap.  Prepare unit for operation.  Fill fuel tank with proper fuel / oil mixture. See fuel and lubrication section
