BEFORE OPERATING CHAIN SAW

1. Read and understand this owner’s manual before operating chain saw.

2. Use chain saw for cutting wood only. Do not use for cutting any non-wood items.

3. Only well-instructed adults should operate chain saw. Never allow children to operate chain saw. First-time user should obtain informed, practical instruction in addition to reading this manual. Practice cutting logs on a saw horse or cradle.

4. Use only electrical voltage noted on model plate of chain saw.

5. Use only extension cords marked for outdoor use. See page 8 for extension cord requirements.

6. Do not operate chain saw

• while under the inﬂuence of alcohol,

medication, or drugs

• in rain or in damp or wet areas

• where highly ﬂammable liquids or

gases are present

• if saw is damaged, adjusted wrong,

or not fully assembled

• if trigger does not turn saw on and

off. Chain must stop moving when you release trigger. Have faulty switch replaced by authorized service person.

• while tired or in a hurry

• while in tree or on a ladder unless

trained to do so

7. Wear snug-ﬁtting clothes when operating chain saw. Do not wear loose clothing or jewelry . They can get caught in moving saw chain.

Safety

8. Wear the following safety gear when operating chain saw:

• heavy-duty gloves (wear rubber

gloves if working outdoors)

• steel-toed safety footwear with non-

skid soles

• eye protection such as safety glasses,

goggles, or face screen

• safety hard hat

• ear mufﬂers or ear plugs

• hair covering to contain long hair

• face or dust mask (if working in dusty

areas)

9. Before cutting, always provide the following:

• clear work area

• secure footing

• planned retreat path from falling tree

10. Inspect tree before cutting down. Make sure there are no dead limbs or branches that may fall on you.

KICKBACK

WARNING: Avoid Kickback. Kickback can cause you to lose control of chain saw. Kickback can cause severe injury or death.

Kickback Safety Devices On This Saw

This saw has a low-kickback chain and reduced-kickback guide bar. Both items reduce the chance of kickback. Kickback can still occur with this saw. Do not let tip of guide bar touch anything when chain is moving.

Never hold the chain saw by the front hand guard.

Cause Of Kickback

Kickback may occur when nose or tip of guide bar touches an object while chain is moving. If chain cutter catches on object, a sudden reverse action will result. The guide bar will kick up and back towards operator.

Kickback may also occur when wood pinches chain at guide bar nose. A sudden reverse action will also result.

The following steps will reduce the risk of kickback:

• Use both hands to grip saw while saw is running. Use ﬁrm grip. Thumbs and ﬁngers must wrap around saw handles.

• Keep all safety items in place on saw. Make sure they work properly.

• Do not overreach or cut above shoulder height.

• Keep solid footing and balance.

• Stand slightly to left side of saw. This keeps your body from being in direct line with chain.

• Do not let guide bar nose touch anything when chain is moving (see Figure 1).

• Never try cutting through two logs at same time. Only cut one log at a time.

• Do not bury guide bar nose or try plunge cut (boring into wood using guide bar nose).

• Watch for shifting of wood or other forces that may pinch chain.

• Use extreme caution when re-entering a previous cut.

• Use low-kickback chain and guide bar supplied with this chain saw. Only replace these parts with chains and guide bars listed in this manual.

• Never use dull or loose chain. Keep chain sharp and tensioned correctly.

Saw Maintenance and Kickback Safety

Follow maintenance instructions in this manual. Proper cleaning of saw and chain and guide bar maintenance can reduce chances of kickback. Inspect and maintain saw after each use. This will increase the service life of your saw.

Note:

Even with proper sharpening, risk of

kickback can increase with each sharpening.

PUSHBACK AND PULL-IN

WARNING: Avoid pushback and pull-in. These hazards can cause you to lose control of chain saw. Pushback or pull-in can cause severe injury.

Cause Of Pushback and Pull-In

Pushback may occur while cutting with top of guide bar. Pushback will force saw back towards you. Pull-in may occur while cutting with bottom of guide bar. Pull-in will force saw in towards wood you are cutting. These hazards can occur if chain is pinched, caught, or contacts a non-wood object.

The following steps will reduce the risk of pushback or pull-in:

• Use both hands to grip saw while saw is running. Use ﬁrm grip. Thumbs and ﬁngers must wrap around saw handles.

• Do not overreach or cut above shoulder height.

• Keep solid footing and balance.

• Stand slightly to left side of saw. This keeps your body from being in direct line with chain.

• Have saw running at full speed before starting a cut.

• When cutting, make sure spike of saw is against wood (pull-in only). See Prod- uct Identification, page 6, to locate spike.

• Never try cutting through two logs at same time. Only cut one log at a time.

• Watch for shifting of log or other forces that may pinch chain.

• Use extreme caution when re-entering a previous cut.

• Do not twist saw when removing guide bar from undercut.

• Use wedges made of plastic, wood, or light alloy (never steel or iron) to hold cut open.

CHAIN SAW OPERATION

1. Stay alert. Use common sense while op-

erating chain saw.

2. Keep work area clean. Cluttered areas

invite injuries.

3. Be aware of extension cord while op-

erating chain saw . Be careful not to trip over cord.

4. Keep children, animals, and bystand-

ers away from chain saw and extension cord. Only chain saw user should be in work area.

5. Do not cut down a tree unless you are

trained or have expert help.

6. If two or more persons perform buck-

ing and felling operations at the same time, provide plenty of distance between operations. Provide distance of at least twice the height of tree being felled.

7. Secure wood you are cutting by using

clamps or chocks.

8. Grip chain saw ﬁrmly with both hands.

Never operate chain saw with one hand. Never use hand guard as handle.

9. Keep ﬁnger off trigger until ready to

make cut.

10. Before starting chain saw, make sure

11. A void body contact with grounded ob-

jects such as pipes, wire fences, and metal posts.

12. Keep all parts of body away from chain

when saw is running.

13. Do not force chain saw while cutting.

Apply light pressure.

14. Cut small brush and saplings with ex-

treme care. Slender material may catch in chain and be whipped toward you. This could also pull you off balance.

15. When cutting limb or tree trunk that is under tension, use extreme caution. Be alert for wood springing back. When wood tension is released, limb could spring back and strike operator causing severe injury or death.

16. Do not activate the chain brake to stop saw . Al ways release trigger to stop saw .

17. Carry chain saw from one place to another

• with chain saw unplugged

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

1. Make ﬁrst cut 15 centimeters (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 Figure 10).

2. Move five to ten centimeters (two to four inches) farther out on limb. Make second cut from above 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.

CAUTION: Seek professional help if facing conditions beyond your ability.

CUTTING WITH THE CHAIN SAW

1. Connect saw to extension cord. Connect extension cord to power supply.

2. Make sure section of log to be cut is not laying on ground. This will keep chain from touching ground as it cuts through log. Touching ground with moving chain will dull chain.

3. Use both hands to grip saw . Al ways use left hand to grip front handle and right hand to grip rear handle. Use ﬁrm grip. Thumbs and ﬁngers must wrap around saw handles (see Figure 9).

4. Make sure your footing is ﬁrm. Keep feet apart. Divide your weight evenly on both feet. Stand slightly to left side of saw . This keeps your body from being in direct line with chain.

5. When ready to make a cut, press in switch lockout with right thumb and squeeze trigger (see Figure 9). This will turn saw on. Releasing trigger will turn saw off. Make sure saw is running at full speed before starting a cut.

• Do not fell a tree without ample skill or expert help.

• Keep children, animals, and bystanders away from area when felling a tree.

• If two or more persons perform bucking and felling operations at the same time, provide ample distance between operations. Provide distance of at least twice the height of tree being felled.

WARNING: When felling a tree, be aware of your surroundings. Do not endanger any person, strike utility lines, or cause property damage. If tree strikes utility lines, contact utility company at once.

CAUTION: Seek professional help if facing conditions beyond your ability.

Felling is the process of cutting down a tree. Make sure your footing is ﬁrm. Keep feet apart. Divide your weight evenly on both feet. Follow directions below to fell a tree.

, page 3 to avoid

Before Felling a Tree

1. Before felling, inspect tree. Make sure there are no dead limbs or branches that may fall on you. Study natural lean of tree, location of larger branches, and wind direction. This will help you judge which way tree will fall.

2. Clear work area around tree.

3. Plan and clear a retreat path before felling. Make retreat path opposite to planned direction of fall of tree and at 45° angle (see Figure 11).

4. Remove dirt, stones, loose bark, nails, staples, and wire from tree where you will make felling cuts.

5. Stay on uphill side when felling tree. Tree could roll or slide downhill after falling.

Felling Procedure

Felling Notch

A properly placed felling notch will determine direction tree will fall. Place felling notch on side of tree in direction you want tree to fall (see Figure 12, page 11). Follow directions below to create a felling notch.

1. Make lower notch cut as close to ground as possible. Hold saw so guide bar is horizontal. Cut 1/3 the diameter of tree trunk (see Figure 12, page 11). Always make this horizontal lower notch cut ﬁrst. If you make this cut second, tree can pinch chain or guide bar.

2. Start upper notch cut the same distance above ﬁrst cut as ﬁrst cut is deep.

Example:

If lower notch cut is 20 centimeters deep (eight inches), start upper notch cut 20 centimeters (eight inches) above it. Cut downward at 45° angle. The upper notch cut should meet end of lower notch cut (see Figure 12, page 11).

3. Remove tree trunk wedge created by notching cuts.

Note:

Felling Cut

1. Make felling cut five centimeters (two inches) higher than lower notch cut and on opposite side of tree (see Figure 12, page 11). K eep felling cut par allel to lower notch cut.

2. Cut towards notch.

WARNING: Do not cut all the way through tree. Leave about five centimeters (two inches) of tree diameter uncut directly behind felling notch (see Figure 12). This uncut portion acts as a hinge. The hinge helps keep tree from twisting and falling in wrong direction.

3. As felling cut nears hinge, tree should begin to fall. wedges into felling cut to control direction of fall. If tree settles back and pinches chain, drive wedges into felling cut to remove saw. Only use wedges made of wood, plastic, or aluminum. Never use wedge made of steel. This could cause kickback and damage to chain.

4. When tree begins to fall, quickly

• remove saw from felling cut

• release trigger to turn saw off

• put saw down

• exit area using retreat path

WARNING: Be alert for falling overhead limbs. Watch your footing while exiting area.
