IMPORTANT: Read and understand this manual before assembling or operating this chain saw. Improper use of saw can cause severe injury. Keep this manual for future reference.

BEFORE OPERATING SAW

1. Watch what you are doing. Use common sense. Do

not operate saw when you are tired.

2. Only well-instructed adults should operate chain

saw. Never allow children to operate chain saw.

3. Use proper extension cord.

4. Do not operate chain saw

• in rain or in damp or wet areas

• if saw is damaged, adjusted wrong, or not fully and securely assembled

• while in tree or on a ladder

5. Wear snug-ﬁtting and protective clothes including gloves, safety shoes, goggles, safety helmet, and ear plugs. Use rubber gloves and shoes if working outdoors.

6. Before cutting, provide a clear work area, secure footing, and planned retreat path from falling tree.

7. The typical hand-arm vibration at full load while cutting wood when tested in accordance to ISO/ DIS 7205 is 23.8 M/S2.

8. The typical A-weighted noise levels at full load while cutting wood when tested in accordance to ISO 7182 are:

Sound Pressure Level 95 DB(A) Sound Power Level 100 DB(A)

WHILE OPERATING SAW

1. Keep children, animals, and bystanders away from chain saw and extension cord. Only chain saw user should be in work area.

2. Grip chain saw ﬁrmly with both hands. Thumbs and fingers must wrap around saw handles. Never operate chain saw with one hand. Never use hand guard as handle.

3. Secure wood you are cutting by using clamps or chocks.

4. Keep all parts of body away from chain when saw is running.

5. Cut small brush and saplings with extreme care. Slender material may catch in chain and be whipped toward you or pull you off balance.

6. When cutting limb or tree trunk that is under tension, use extreme caution. Be alert for wood springing back. When tension is released, limb could spring back and strike you.

7. Do not activate the chain brake to stop saw. Always release trigger to stop saw.

8. Carry chain saw from one place to another

• with finger off trigger, saw stopped, and

unplugged

• by holding front handle with guide bar and chain

to rear

KICKBACK

WARNING: Beware of kickback.

Kickback may occur when the nose or tip of the guide bar touches an object (see Figure B), or when the wood closes in and pinches the saw chain in the cut. Tip contact may cause a lightning fast reverse reaction, kicking the guide bar up and back towards the operator (see Figure B). 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 user.

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.

• 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 B).

•Watch for shifting of wood or other forces that

may pinch chain.

•Never use dull or loose chain. Keep chain sharp

with proper tension.

SAW CHAIN TENSION ADJUSTMENT

WARNING: Maintain proper chain tension always. A loose chain will increase the risk of kickback. A loose chain may jump out of guide bar groove. This may injure operator and damage chain. A loose chain will cause chain, guide bar, and sprocket to wear rapidly.

Note:

For pre assembled models, the saw chain tension is properly set at factory. A new chain will stretch. Check new chain after first few minutes of operation. Allow chain to cool down. Follow steps below to readjust saw chain tension.

1. Before adjusting chain, make sure guide bar nuts

are only ﬁnger tight (see Figure D and E). Also make sure adjusting block is in oval adjusting hole on guide bar (see Figures D, E, and F).

2. Turn adjusting screw clockwise until all slack is

out of chain (see Figure G). no gap between side links of chain and bottom of guide bar (see Figure H).

3. Wearing protective gloves, move chain around

guide bar. Chain should move freely. If chain does not move freely, loosen chain by turning adjusting screw counterclockwise.

4. After chain tension is correct, tighten guide bar nuts

ﬁrmly. If not, guide bar will move and loosen chain tension. This will increase the risk of kickback. This can also damage saw. Check new chain after ﬁrst few minutes of operation. Allow chain to cool down. Readjust chain tension.

FILLING OIL TANK

1. Remove oil cap.

2. Fill oil tank with SAE #30 motor oil. Grain-based biodegradable bar and chain lubricants made from rapeseed oil, canola oil, or sunflower oil bases also provide acceptable performance. temperatures below -1°C, use SAE #10 oil. For temperatures above 24°C, use SAE #40 oil.

3. Replace oil cap at once. Tighten oil cap ﬁrmly for good seal. This will avoid oil seepage from tank.

4. Wipe off excess oil.

Note:

It is normal for oil to seep when saw is not in use.

Empty oil tank after each use to prevent seepage.

OPERATING CHAIN SAW

EXTENSION CORDS

Use proper extension cord with this chain saw. Use a HO7RN extension cord with no less than 1.5 mm2 wire at distances up to 30 meters. Use a ground fault circuit interrupter as part of the power supply system.

Use an extension cord heavy enough to carry the current your saw will draw. An undersized cord will cause a voltage drop at the saw, loss of power, and overheating.

Keep cord away from cutting area. Make sure cord does not catch on branches or logs during cutting. Inspect cords often. Replace damaged cords.

OILING SAW CHAIN

Always check oil level before using saw. To oil chain, press squeeze bulb on oil cap. Do not attempt to operate the oiler while cutting with the saw. Oil will feed onto guide bar and chain. Press squeeze bulb on oil cap at least once before each cut. Check oil level often by looking at oil sight level hole. Oil sight level hole is on left side of saw, between front handle and front hand guard.

CUTTING WITH THE CHAIN SAW

1. Connect saw to power supply.

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

3. Firmly grip saw as shown in Figure I. Thumbs and ﬁngers must wrap around saw handles.

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 I). This will turn saw on. Releasing trigger will turn saw off. Make sure saw is running at full speed before starting a cut.

6. When starting a cut, place moving chain against wood. Hold saw ﬁrmly in place to avoid possible bouncing or skating (sideways movement) of saw.

7. Guide saw using light pressure. Do not force saw. Overload can cause motor burn out.

CHAIN BRAKE (Models EL-4 and EL-7B only)

The chain brake quickly stops the saw chain. Kickback causes the back of operator’s left hand to contact front hand guard (see Figure J). When front hand guard moves forward, the saw chain stops. This reduces the chance of serious injury during kickback. When the chain brake activates, release trigger at once.

To reset chain brake, release trigger and move front hand guard back into position. You must release trigger first. If not, the saw will start when you reset the front hand guard.

CAUTION: Do not use the chain brake to stop and start your saw. Quick repeated stops may cause overheating of the chain brake. Damage to the chain brake will occur.

Note:

Test chain brake before each use. Firmly grip saw with both hands. With saw running, move front hand guard forward with back of left hand. Keep both hands on the handles. Saw chain should stop. If chain brake does not work, have saw repaired by authorized service person.

TRIMMING A TREE (Pruning)

Trimming a tree is the process of cutting limbs from a living tree. Follow directions below to trim a tree.

1. Make ﬁrst cut 15 cm 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 K).

2. Move 5 to 10 cm 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.

FELLING A TREE

(Cutting Down a Tree)

WARNING: Do not fell a tree without ample

skill or expert help. 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.

Felling is the process of cutting down a tree. Follow directions below to fell a tree.

Before Felling a Tree

1. 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 L).

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 A) 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 M). 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 M). 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. cut is 20 cm deep, start upper notch cut 20 cm above it. Cut downward at 45° angle. The upper notch should meet end of lower notch cut (see Figure M).

3. Remove tree trunk wedge created by notching cuts.

B) Felling Cut

1. Make felling cut 5 cm higher than lower notch cut and on opposite side of tree (see Figure M). Keep felling cut parallel to lower notch cut.

2. Cut towards notch.

WARNING: Do not cut all the way through tree. Leave about 5 cm of tree diameter uncut directly behind felling notch (see Figure M). This uncut portion acts as a hinge. The hinge helps keep tree from twisting and falling in wrong direction.

Example:

Note:

Always

If lower notch

cut

3. As felling cut nears hinge, tree should begin to fall.

Note:

If needed, drive 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 and put saw down

•exit area using retreat path

LIMBING A TREE

Limbing is removing branches from a fallen tree. Do not remove larger limbs under tree that support log off ground. Remove each limb with one cut (see Figure N). Clear cut limbs from work area often. This will help maintain a safe work area.

Make sure you start your cut where limb will not pinch saw during cutting. To avoid pinching, start cut on freely hanging limbs from above limb. Start cut on limbs under tension from under limb. If pinch occurs, turn saw off, lift limb, and remove saw.

BUCKING A LOG

WARNING:

• If on slope, make sure log will not roll down hill. Secure log by using wooden stakes. Stand on uphill side of log while cutting.

• While cutting log, never hold log with your hand, leg, or foot or allow another person to hold log.

Bucking a log is cutting a log into sections. When possible, raise log or section off ground. Do this by using limbs, logs, chocks, etc.

When cutting through log, maintain control by reducing cutting pressure near end of cut.

Follow directions below to buck a log.

Entire Length Of Log On Ground

1. Cut log from top (see Figure O).

Log Supported On One End

1. Make ﬁrst cut on underside of log (see Figure P). Use top of guide bar to make this cut. Cut 1/3 through diameter of log. This cut will keep section from splintering when cut.

2. Make second cut directly above ﬁrst cut. Cut down to meet ﬁrst cut. This cut will keep log from pinching guide bar and chain.
