WARNING

2-2. 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 because rotational kickback and pinch kickback are major chain saw operational dangers and the leading cause of most accidents.

BEWARE OF: ROTATIONAL KICKBACK (Figure 2-2A)

A =

Kickback path

B = Kickback reaction zone

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.

2 - SAFETY PRECAUTIONS

2-3. IMPORTANT SAFETY INSTRUCTIONS

WARNING

When using an electric chain saw, basic safety precautions should always be followed to reduce the risk of fire, electric shock, and injury to persons, including the following:

READ ALL INSTRUCTIONS

1. Double insulated - No Serviceable Parts Inside.

2. To reduce the risk of electric shock, this equipment has a polarized plug (one blade is wider then the other). This plug will fit in a polarized outlet only one way. If the plug does not fit fully in the outlet, reverse the plug. If it still does not fit, contact a qualified electrician to install the proper outlet. Do not change the plug in any way.

3. With a basic understanding of kickback, you can reduce or eliminate the element of surprise. Sudden surprise contributes to accidents.

4. 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.

5. GUARD AGAINST ELECTRIC SHOCK: Prevent body contact with grounded surfaces (i.e., metal pipes, wire fences).

6. CONSIDER THE WORK AREA ENVIRONMENT: Use extreme caution when cutting small sized brush and sapling, as slender material may catch the saw chain and be whipped toward you or pull you off balance. Do not operate a chain saw in a tree unless you are 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 the presence of flammable liquids or gases.

7. KEEP CHILDREN AND BYSTANDERS AWAY: Do not let visitors contact the chain saw or extension cord. All visitors should be kept away from the work area.

8. STORING YOUR CHAIN SAW: When not in use, chain saws should be stored out of a dry, high or locked-up place. When storing saw, use a scabbard or carrying case.

9. DO NOT FORCE THE CHAIN SAW: The chain saw will do a better and safer job when used at the rate for which it was intended.

10. 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 reach of children, in

11. DRESS PROPERLY: Do not wear loose clothing or jewelry, as they can get caught in moving parts. Nonskid footwear is recommended when working outdoors. Wear protective hair covering to contain long hair.

12. USE SAFETY GEAR: UsE safetY glasseS, safety footwear, safety chaps, snug fitting clothing, protective gloves, and protective hearing and head gear.

13. STAY ALERT: Watch what you are doing. Use common sense. Do not operate the chain saw when are tired. Keep all parts of your body away from the saw chain when the motor is operating. Before you start the saw, make sure the saw chain is not contacting anything.

14. MAINTAIN YOUR CHAIN SAW: Inspect the chain saw cords periodically and, if damaged, have them repaired by an authorized service facility. Keep the cord clear of the chain and operator at all times. Never carry the saw by the cord or pull it to disconnect from receptacle. Keep the cord from oil and sharp edges. Inspect the extension cords periodically and replace if damaged. Keep tools sharp and clean for better and safer performance. Follow instructions for lubricating and changing accessories. Keep handles dry, clean and free from oil and grease.

15. DISCONNECT THE CHAIN SAW: Disconnect the chain saw when not in use, before servicing, and when changing accessories and attachments such as saw chain and guard.

16. OUTDOOR sion cords intended for use outdoor use and so marked accordingly.

17. CHECK DAMAGED PARTS: Before further use of the chain saw, a guard or other part that is damaged should be carefully checked to determine that it will operate properly and perform its intended function. Check for alignment of moving parts, binding of moving parts, breakage of parts, mounting, and any other conditions that may affect its operation. A guard or other part that is damaged should be properly repaired or replaced by an authorized service center, unless otherwise indicated in this instruction manual.

Have defective switches replaced by authorized service centre. Do not use chain saw if switch does not turn it on and off. Do not operate a chain saw that is damaged, improperly adjusted, or is not completely and securely assembled. Be sure that the saw chain stops moving when the trigger is released.

18. CARRYING THE SAW: Carry the saw by the front handle with the saw stopped. Keep your finger off the switch, and make sure that the guide bar and saw chain are to the rear.

EXTENSION CORDS: Use only exten-

you

19. GUARD AGAINST KICKBACK:

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 lightning-fast reverse action, kicking the guide bar rapidly 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. 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.

B. Do not over reach. C. Keep proper footing and D. Do not 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, which reduce the risks associated with kick-

back. G. Use only 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.

20. POWER SUPPLY: Connect the chain saw to correct voltage; be sure that the voltage supplied is the same as that specified on the nameplate of the tool.

21. 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 trigger is released.

22. DO NOT attempt operations beyond your capacity or experience.

23. DO NOT operate a chain saw with one hand! Serious injury to the operator, helpers, or bystanders result from one-handed operation. A chain saw is intended for two-handed use.

24. TO REDUCE potential for electric shock, do not operate the saw on wet or slippery surfaces, or during snow storms, rain storms, and other adverse weather conditions.

25. DO NOT allow dirt, debris or sawdust to build up on the motor or outside air vents.

26. Follow the manufacturer’s sharpening and maintenance instructions for the saw chain.

27. Cut at high motor speeds.

3-5. 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 3-5A).

TO ADJUST SAW CHAIN TENSION:

1. Loosen the bar retaining nuts (D) so they are hand tight. (See Fig. 3-5B)

2. Holding the nose of the bar up, use the screwdriver or scrench if provided in your User’s Kit to turn the guide bar adjustment screw (E) (Fig. 3-5C) clockwise to tighten the chain. Turning the screw COUNTERCLOCKWISE LOOSENS THE CHAIN on the guide bar.

3. 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. Do not move chain with bare hands.

NOTE: IF the chain is difficult to rotate or if it binds on the guide bar, too much tension has been applied and must be adjusted. To decrease tension, turn the adjustment screw counterclockwise slowly. Move the chain back and forth until it moves freely.

3-7. ADJUSTING POLE LENGTH

The pole saw has a telescoping pole assembly that will extend from 57 inches (fully retracted) to 96 inches (fully extended). A threaded compression coupling is used to hold the pole in position at any extended length.

1. To extend the pole, loosen coupling by turning coupling nut counterclockwise as shown in Fig.3-7A. Pole will slide freely.

2. Pull inner pole section out to desired length of extension. Note: Only extend pole to minimum length required to reach limb that is being cut.

3. To lock pole in position, tighten coupling by turning coupling nut clockwise (See Fig. 3-7A) until firmly hand tight. Make sure saw handle is aligned with pole handle before tightening coupling nut. IMPORTANT: Do not use wrench or pliers to overtighten coupling. Damage to coupling or pole may result.

CAUTION

If a chain is TOO LOOSE or TOO TIGHT, the bar chain and saw bearings will wear more rapidly. Study Figure 3-5A for information concerning correct cold tension (A), correct warm tension (B), and as a guide for when saw chain needs adjustment (C).

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. TRIMMING A TREE (PRUNING)

WARNING

Avoid kickback. Kickback can result in severe injury or death. See Kickback, page 6, to avoid risk of kickback. Do not operate pole saw while in a tree, on a ladder or any other unstable work surface, or in any awkward position. You may lose control of pole saw causing severe injury. Do not extend arms above shoulders when using pole saw. Seek professional help if facing conditions beyond your ability.

Trimming a tree is the process of cutting limbs from a living tree. Make sure footing is firm. Keep feet apart. Divide your weight evenly on both feet.

1. Make first cut six inches from tree trunk on underside of limb. Use top of guide bar to make this cut. (Cut 1/3 through diameter of limb, see Fig. 5-1A)

2. Move two to four inches farther out on limb. Make second cut from above limb. limb. Continue cut until you cut limb off.

3. Make third cut as close to tree trunk as possible on underside of limb stub. Use top of guide bar to make this cut. Cut 1/3 through diameter of stub.

4. Make fourth cut directly above third cut. Cut down to meet third cut. This will remove limb stub.

5-2. FELLING

Felling is the term for cutting down a tree. Small trees up to 6-7” (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.

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.

5-2A

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” (3-5cm) above the edge of the notch (C) (Figure 5-2B).

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 5-2A.

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:

1. Use wooden or plastic wedges (G) to prevent binding the bar or chain (H) in the cut. Wedges also control felling (Figure 5-2C).

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

5-3. 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 5-3A). 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.

6-1. 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.

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.

TO CLEAN GUIDE BAR RAILS:

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

4).

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 6-1A).

3. Reinstall the bar, chain and bar bolt retaining nuts. (See Section 3-4).

6-2. CHAIN MAINTENANCE INSTRUCTIONS

WARNING

Unless you have experience and 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 kick saw chain should always be used in combination with other kickback protection devises such as a hand guard and reduced kickback guide bar supplied with the your unit. Always use a replacement saw chain designed as “lowkickback” or a saw chain which meets the low-kickback performance. 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.

What is a Low-Kickback Saw Chain?

A low-kickback saw chain is a chain which has met the kickback performance requirements of use other replacement chain unless it has met these requirements for your specific model.

By keeping the 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 hand guard, reduced kickback guide bar and low kick back 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 3-5, Saw Chain Tension Adjustment).

BREAKING IN A NEW SAW CHAIN

A new chain and bar will need readjustment after as few 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 McCulloch Authorized Service Center to have this repair performed.

7-1. PREVENTATIVE MAINTENANCE

WARNING

SERVICING A DOUBLE INSULATED CHAIN SAW

In this double insulated chain saw, 2 systems of insulation, instead of grounding, are provided. No grounding means is provided on a double insulated chain saw, nor should a means for grounding be added to the chain saw. No serviceable parts are inside. A double insulated chain saw is marked with the words, “DOUBLE INSULATION” or “DOUBLE INSULATED”. The symbol (square within a square) may also be marked on the chain saw.

1. Place switch in OFF position and unplug the power supply before the chain saw is serviced, cleaned, or maintenance is performed.

2. Keep the air intake clean and air vents free of debris to avoid overheating the motor.

3. Clean with a damp sponge and mild soap. Do not squirt with a water hose or douse with water or other liquids.

4. Inspect the saw chain for proper tension before each

and frequently during cutting. Sharpen as

use required.

5. Clean the guide bar and bar pad to ensure free path for oil.

6. Turn the bar over after each use to achieve even wear.

7. No motor lubrication is necessary. The motor is equipped with lifetime lubricated bearings.

8. If the saw does not operate, turn switch to OFF position and disconnect the extension cord, first from the power supply, then from the saw. Check the power supply for blown fuses or tripped circuit breakers. If it still does not operate, contact the McCulloch Product Service Department, through the toll-free number listed on the back cover of this manual, for service information. Do not attempt to repair it yourself. No serviceable parts are inside.
