1. REPLACEMENT PARTS - When servicing use only

identical replacement parts.

2. POLARIZED PLUGS - To reduce the risk of electric

shock, this equipment has a polarized plug (one blade is wider than the other). This plug will fit in a polarized extension cord only one way. If the plug does not fit fully in the extension cord, reverse the plug. Do change the plug in any way.

3. KEEP THE WORK AREA CLEAN: Cluttered areas

invite injuries. Do not start cutting until you have a clear work area, secure footing, and a planned retreat path from the falling tree.

4. CONSIDER THE WORK AREA ENVIRONMENT: Use

extreme caution when cutting small sized brush and saplings because the slender material may catch the saw chain and be whipped toward you or pull you off

not

balance. Do not operate a chain saw in a tree unless specifically trained to do so. 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. Do not expose the chain saw to rain. Do not use the chain saw in damp or wet locations. Do not use the chain saw in presence of flammable liquids or gases.

5. GUARD AGAINST ELECTRIC SHOCK: Prevent body contact with grounded surfaces. For example: metal pipes, wire fences.

18. GUARD AGAINST KICKBACK:

ed service center

WARNING: 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. Tip contact in some cases may cause a lightening fast reverse action, 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 injury to the user. The following precautions should be followed to minimize kickback:

A. GRIP SAW FIRMLY: Hold the chain saw firmly

with both hands when the motor is running. Use a firm grip with thumbs and fingers encircling the chain saw handles. Note : If a manual oiler control is provided, additional or modified instruc-

tions regarding its B. Do not over reach. C. Keep proper footing and balance at all times. D. Don’t let the nose of the guide bar contact a log,

branch, ground or other obstruction. E. Do not cut above shoulder height. F. Use devices such as low kickback chain, guide

bar nose guards, chain brakes and special guide

bars that reduce the risks associated with kick-

back. G. Only use replacement bars and chains specified

by the manufacturer or the equivalent. H. There are no other replacement components for

achieving kickback protection in accordance with

CSA Z62.3.

19. POWER SUPPLY: Connect the chain saw to correct voltage, that is, be sure that the voltage supplied is the

To reduce risk of electric shock, do not expose unit to water or operate unit on wet ground.

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 lightening-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. (See Fig. 2-5B “A”)

PINCHING the saw chain along the TOP of the guide bar may PUSH the guide bar rapidly back toward the operator (See Fig. 2-5B “C”).

Any of these reactions may cause you to lose control of the saw, which could result in serious personal injury.

Use of these personal safety items is highly recommended to reduce the risk of accidental injury.

3-1. INTRODUCTION

This unit is designed for occasional homeowner use and should not be used for commercial purposes or subjected to heavy continuous use.

Your new chain saw can be used for a variety of projects such as cutting firewood, making fence posts, felling small trees, limbing, pruning at ground level, and light carpentry. Cut only wood or wood products with your saw.

3-2. ASSEMBLY REQUIREMENTS

Your new chain saw will require adjustment of chain and filling the oil tank with lubricating oil before the unit is ready for operation. Do not start the saw motor until the unit is properly prepared. Read all instructions carefully. Do not install any other size bar and chain than what is recommended for your model.

3-3. GUIDE BAR / SAW CHAIN INSTALLA-

TION

CAUTION

Disconnect the chain saw from power souce before checking or adjusting the chain saw tension.

TO INSTALL GUIDE BAR & SAW CHAIN:

These instructions are for replacing a bar. The unit is fully assembled when shipped. NOTE : Always wear heavy gloves when handling the saw chain.

1. Place power unit on flat surface.

2. Loosen knob (B) slightly by turning knob counterclockwise and then turn the chain tension ring (C) counter-clockwise to relief chain tension. To remove the sprocket cover (A), turn knob (B) counter-clockwise. (Fig. 3-3A)

3. Remove saw chain form around the guide bar and the sprocket. Slide the guide bar, with tension plate (D) attached, from the unit. (Fig. 3-3B)

3-4. SAW CHAIN TENSION ADJUSTMENT

Proper tension of the 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.

NOTE: A new chain and bar will need readjustment after as few as 5 cuts.This is normal during the break-in period, and the interval between future adjustments will lengthen quickly (Figure 3-4A).

CAUTION

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

TO ADJUST SAW CHAIN TENSION:

With no tools system - wear gloves while tensioning chain. NOTE: Make sure the CHAIN BRAKE®is disengaged. Disengage the CHAIN BRAKE®(D) by pulling it backward

(Figure 3-4B).

1. Tensioning the chain is easy. Turn bar bolt knob (E) counter clock wise. Then turn ring (F) counter clock wise to loosen chain or clock wise to tighten chain. (Fig. 3-4C)

2. After adjustment and while wearing heavy duty work gloves, move the saw chain back and forth on the guide bar to be sure the chain moves freely and is in proper mesh with sprocket.

NOTE: If the chain is difficult to rotate or if it binds on the guide bar, too much tension be adjusted as described in step 1

3-5. FILLING OIL TANK

Using a funnel, fill oil tank with Genuine Factory Parts Chain, Bar and Sprocket oil. Wipe up any spills. Make sure no dirt gets into the oil tank.

The saw chain requires lubrication while in use to minimize friction with the guide bar. The oil tank holds 4.5 ozs of oil, enough to lubricate the chain for 12-15 minutes of sawing.

We recommend using Genuine Factory Parts Chain, Bar and Sprocket Oil, which contains additives to reduce friction wear and reduce resin residue formations.

CAUTION

The oil tank level should be frequently checked during operation to avoid starving the bar and chain of lubrication.

NOTE: Your chain saw is equipped with an Automatic Oiler system and is the ONLY source of lubrication for the bar and chain (Figure 3-5A).

4-1. TO START SAW

1. Make sure the CHAIN BRAKE®IS DISENGAGED.The motor will not start if the CHAIN BRAKE®is in the ENGAGED position. Disengage the CHAIN BRAKE by pulling backward toward the motor (Figure 4-1A).

WARNING

Ensure the extension cord is of the proper size and type for your saw.

2. An extension cord retainer (A) (Fig. 4-1B) is built into the rear handle that prevents the extension cord from pulling out of the handle. To use this feature, simply double the extension cord, about a foot from the end, and insert it through the hole at the end of the handle. Hook the loop formed by doubling the cord over the tab. Gently tug on the cord to ensure that it is firmly retained in the saws handle. Plug the receptacle end of the extension cord into the tool’s power supply cord.

WARNING

Make sure the extension cord does not come in contact with the guide bar and saw chain.

3. Grip the saw with both hands, front handle (DO NOT HOLD CHAIN BRAKE®) and the right hand holding the rear handle. Thumbs and fingers should encircle both handles (Figure 4-1C).

4. With your RIGHT THUMB, depress the LOCK/OFF button on the top of the rear handle, and at the same time squeeze the trigger. To stop the saw, release the trigger (Figure 4-1D).

NOTE: It is not necessary to maintain pressure on the LOCK/OFF button once the trigger is squeezed and the motor is running. The LOCK/OFF button is a safety device to avoid accidental starting.

4-2.TO STOP MOTOR

ations is essential to minimize friction with the guide bar. Your chain saw is equipped with an automatic oiler system.

The oiler automatically delivers the proper amount of oil to the bar and chain. There is no flow adjustment.

The oil tank level can be checked in the inspection slot (A) provided on the right side of the saw.Tank is full when oil is at the top of the slot (Figure 4-3A).

CAUTION

Never starve the bar and chain of lubrication oil. Running the saw DRY or with TOO LITTLE OIL will decrease cutting efficiency, shorten chain saw life, and cause rapid dulling of the chain and excessive wear of the bar from overheating. Too little is evidenced by smoke or bar discoloration.

NOTE: The saw chain stretches during use, particularly when it is new, and occasional adjustment will be needed. A new chain requires more frequent adjustment during the break-in period. This is normal. See Section 3-4, Saw Chain Tension Adjustment instructions.

4-5. EXTENSION CORDS

When using an electric chain saw, plug it into the extension cord only when you are ready to cut wood. Connect the extension cord to a 110/120 voltage outlet. see chart 3-6.

CAUTION

A cord that is hot to the touch is overloaded.

WARNING

Do not operate your chain saw in a wet or damp environment. Do not expose the saw to rain, snow or sleet. Moisture will cause short circuits. Replace or repair any damaged or frayed extension cords before using your saw.

Keep the cord away from the cutting area and position the cord so that it will not be caught on branches or other objects during cutting.

DOUBLE INSULATION WHEN SERVICING USE ONLY IDENTICAL REPLACEMENT PARTS

Do not use if the cord or plug is damaged. Your appliance is double insulated to help protect against electric shock. Double insulation construction consists of two(2) separate “layers”of electrical insulation.

Appliances built with this insulation system are not intended to be grounded. As a result, the extension cord used with your appliance can be plugged into any conventional 120 volt electrical outlet.

Normal safety precautions must be observed when operating an electrical appliance. The double insulation system is only for added protection against injury resulting from a possible internal electrical insulation failure.

WARNING

Your double insulated appliance has no serviceable parts inside. Do not attempt to repair it yourself. For service information, contact the McCulloch Product Service Department toll-free number listed on the back cover of this manual.

5-1. 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 Figure 5-1A.

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 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 two (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 5-1B). 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 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.

is lost.

WARNING

Before making the final cut, always recheck the area for bystanders, animals or obstacles.

14 15

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 5-1C).

2. When diameter of wood being cut is greater than the bar length, make 2 cuts as shown (Figure 5-1D).

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 5-1A).

5-2. 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 5-2A). 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.

5-2A

5-3. 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

1. Log supported along entire length: Cut from top (overbuck), being careful to avoid cutting into the ground (Figure 5-3A).

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 (Figure 5-3B).

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 (Figure 5-3C).

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 supporting logs. Be sure the log being cut is securely supported.

, always stand on the uphill side.

5-3C

5-4.BUCKING USING A SAWHORSE

For personal safety and ease of cutting, the correct position for vertical bucking is essential (Figure 5-4A).

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.

6-1. GUIDE BAR MAINTENANCE

WARNING

Ensure that the power cord is disconnected before performing any maintenance on your saw.

Proper maintenance of the guide bar, as explained in this section, is essential to keep your saw in good working order.

SPROCKET TIP LUBRICATION:

(For units supplied with sprocket tip guide bars only.)

CAUTION

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 each saw use. Always thoroughly clean the guide bar sprocket tip before lubrication.

Tool for lubrication: McCulloch Lube Gun (disposable) This grease gun is designed to fit the small lubrication point

on the guide bar. The disposable Lube Gun is packed with grease. For infor-

mation on where to purchase a lube gun, contact the McCulloch Product Service Department toll-free number listed on the back cover of this manual.

TO LUBRICATE SPROCKET TIP:

WARNING

Wear heavy duty work gloves when performing this application to reduce risk of personal injury.

1. Unplug the chain saw from the power source. 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 disposable Lube gun, insert tip of lube gun into the lubrication hole and inject grease until it appears at the outside edge of the sprocket tip (Figure 6-1A).

4. Make sure that the CHAIN BRAKE Rotate the saw chain by hand. Repeat the lubrication procedure until the entire sprocket tip has been greased.

is deactivated.

GUIDE BAR MAINTENANCE

Most guide bar problems can be prevented merely by keeping the chain saw well maintained.

Incorrect filing and non-uniform cutter and depth gauge settings cause most guide bar problems, primarily resulting in uneven bar wear. As the bar wears unevenly, the rails widen, which may cause chain clatter and difficulty in making straight cuts.

Insufficient guide bar lubrication and operating the saw with a chain that is TOO TIGHT will contribute to rapid bar wear (see Section 6-2).

To help minimize bar wear, the following guide bar maintenance is 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 the saw has been heavily used or if the saw chain appears dirty. Rails should always be cleaned every time the saw chain is removed.

OIL PASSAGES - Oil passages at bar pad should be cleaned to ensure proper lubrication of the bar and chain during operation. This can be done using a soft wire small enough to insert into the oil discharge hole.

NOTE: The condition of the oil 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.

passages can be easily

TO CLEAN GUIDE BAR RAILS:

1. Remove sprocket cover, bar and chain. (see Section 3-3)

2. Using a screwdriver, putty knife, wire brush or other similar instrument, clear residue from the rails on the guide bar.This will keep the oil passages open to provide proper lubrication to the bar and chain (Figure 61B).

3. Reinstall the bar, chain, sprocket cover and bar bolt knob. (See Section 3-3).

6-2. CHAIN MAINTENANCE INSTRUCTIONS

WARNING

Unless you have experience and specialized training for dealing with kickback (see Safety Precautions), always use a low-kickback saw chain, which significantly reduces the danger of kickback. Low-kickback saw chain does not completely eliminate kickback. A low-kickback or “safety chain”, should never be regarded as total protection against injury.

A low-kickback saw chain should always be used in conjunction with other kickback protection devices such as the CHAIN BRAKE

Always use a replacement saw chain designed as “lowkickback” or a saw chain which meets the low-kickback performance requirements of ANSI (American National Standards Institute).

A standard saw chain (a chain which does not have the kickback reducing guard links) should only be used by an experienced professional chain saw operator.

/Hand Guard furnished with your unit.

WHAT IS A LOW-KICKBACK SAW CHAIN?

A low-kickback saw chain is a chain which has met the kickback performance requirements of ANSI B175.1.

By keeping the CHAIN BRAKE®and saw chain in good working condition and correctly serviced as recommended in this manual, you will be able to maintain the safety system of your chain saw over the life of the product.

WARNING

Never remove, modify or make inoperative any safety device furnished with your unit. The CHAIN BRAKE®/Hand Guard and low-kickback saw chain are major safety features provided for your protection.

WARNING

Always wear heavy duty protection work gloves and disconnect the extension cord when working on the saw chain.

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. (See Section 3-4, Saw Chain Tension Adjustment).

BREAKING IN A NEW SAW CHAIN

A new chain and bar will need readjustment after as few as five (5) cuts.This is normal during the break-in period, and the interval between future adjustments will begin to lengthen quickly.

Over a period of time, however, the moving parts of the saw chain will become worn, resulting in what is called CHAIN STRETCH. This is normal. When it is no longer possible to obtain correct chain tension adjustment, a link will have to be removed to shorten the chain. See your nearest Authorized Service Center to have this repair performed.

WARNING / CAUTION

Never have more than three (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 Factory Parts Chain, Bar and Sprocket Oil.

Adequate lubrication of the bar and chain during cutting operations is essential to minimize friction bar.

Never starve the bar and chain of lubricating oil. Running the saw dry or with too little oil will decrease rapid cutting efficiency, shorten saw chain life, cause rapid dulling of the chain, and lead to excessive wear of the bar from overheating. Too little oil is evidenced by smoke or bar discoloration.
