face or dust mask (if working in dusty areas)

10.Before cutting, always provide the following:

clear work area

secure footing

planned retreat path from falling tree

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

12.To reduce the risk of electric shock, this saw has a polarized plug (one blade is wider than the other). This plug will fit in a polarized outlet only one way. If the plug does not fit fully in the outlet of your extension cord, reverse the plug. If it still does not fit, a polarized extension cord will be necessary. Do not change the plug in any way.

WHILE OPERATING SAW

1.Stay alert. Use common sense while operating chain saw.

2.Keep work area clean. Cluttered areas invite injuries.

3.Be aware of extension cord while operating chain saw. Be careful not to trip over cord. Keep cord away from chain and operator at all times.

4.Keep children, animals, and bystanders 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 bucking 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 chain is not touching anything.

11.To guard against electrical shock, avoid body contact with grounded objects such as pipes, 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. It will do the job better and safer at the rate for which it was intended.

14.Cut small brush and saplings with extreme 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.Carry chain saw from one place to another

with saw stopped and unplugged

by holding front handle (never use hand guard as handle)

with finger off trigger

with guide bar and chain to rear

SAFETY

WARNINGS

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 reaction, 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 user.

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.

Properly install front hand guard. This item can reduce injuries from kickback. Follow assembly instructions on page 6. Do not remove front hand guard. Do not replace front hand guard with substitute.

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 at all times

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).

Direction

Do Not Let

Guide Bar

Touch Here

90° Quadrant

Figure 1 - Kickback Hazard Example: Do Not Let Nose of Guide Bar Touch Object While Chain is Moving

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.

SAW CHAIN

TENSION

ADJUSTMENT

WARNING: Unplug chain saw from power source before adjusting saw chain tension.

WARNING: Cutting edges on chain are sharp. Use protective gloves when handling chain.

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 3, page 6).Also make sure adjusting block is in oval adjusting hole on guide bar (see Figures 3 and 4, page 6).

2.Turn adjusting screw clockwise until all slack is out of chain (see Figure 5). Note: There should be no gap between side links of chain and bottom of guide bar (see Figure 6).

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. Note: A new chain will stretch. Check new chain after first few minutes of operation. Allow chain to cool down. Readjust chain tension.

OILING 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.

Figure 8 - Pressing Squeeze Bulb on Oil Cap to Oil Chain

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. Always 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.

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.

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. The motor will overload and can burn out. It will do the job better and safer at the rate for which it was intended.

8.Remove saw from a cut with saw running at full speed. Stop saw by releasing trigger. Make sure chain has stopped before setting saw down.

9.Practice until you can maintain a steady, even cutting rate.
