A. Kickback Safety Precaution for Chain Saw Users

WARNING!

B. Other Safety Precautions

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
personal injury.

®

The Kick Guard

saw. The Kick Guard ® can be used in a majority
of cutting operations, and is especially recom­mended for beginners, homeowners, or chain

saw novices. Most cutting operations can be ac­complished with the Kick Guard® in place.

device is not installed on the

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

2. Keep a good rm grip on the saw with both
hands, the right hand on the rear handle, and
the left hand on the front handle, when the

engine is running. Use a rm grip with thumbs
and ngers encircling the chain saw handles.
A rm grip will help you reduce kickback and

maintain control of the saw. Don’t’ let go.

3. Make sure that the area in which you are cut­ting is free from obstructions. Do not let the
nose of the guide bar contact a log, branch,
or any other obstruction which could be hit
while you are operating the saw.

4. Cut at high engine speeds.

Do not rely exclusively upon the safety devices
built into your saw. As a chain saw user, you

5. Do not overreach or cut above shoulder
height.

should take several steps to keep your cutting
jobs free from accident or injury.

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

7. Only use replacement bars and chains speci-

ed by the manufacturer or the equivalent.

1. Do not operate a chain saw with one hand! Serious injury to the operator, helpers, bystanders, or
any combination of these persons may result from one-handed operation. A chain saw is intended
for two-handed use.

2. Do not operate a chain saw when you are
fatigued.

3. Use safety footwear; snug-tting clothing;

protective gloves; and eye, hearing and head
protection devices. Wear protective hair cov­ering to contain long hair.

4. Use caution when handling fuel. Move the
chain saw at least 3 m (10 feet) from the fuel­ing point before starting the engine.

5. Do not allow other persons to be near the
chain saw when starting or cutting with the
chain saw. Keep bystanders and animals out
of the work area.

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

7. Keep all parts of your body away from the saw
chain when the engine is running.

8. Before you start the engine, make sure that
the saw chain is not contacting anything.

9. Carry the chain saw with the engine stopped,
the guide bar and saw chain to the rear, and

the mufer away from your body.

10. 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 throttle control
trigger is released.

11. Shut off the engine before setting the chain
saw down.

12. Use extreme caution when cutting small size
brush and saplings because slender material
may catch the saw chain and be whipped
toward you or pull you off balance.

13. 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 bers is

released.

14. Keep the handles dry, clean, and free of oil
or fuel mixture.

16. Do not operate a chain saw in a tree unless

you have been specically trained to do so.

17. All chain saw service, other than the items
listed in the Instruction Manual mainte­nance instructions, should be performed
by competent chain saw service personnel.
(For example, if improper tools are used to

remove the ywheel or if an improper tool is
used to hold the ywheel in order to remove
the clutch, structural damage to the ywheel
could occur and could subsequently cause
the ywheel to burst.)

18. When transporting your chain saw, use the
appropriate guide bar scabbard.

19. Spark arrestor mufers approved to SAE

Standard J335b are Standard on ECHO
Chain saws to reduce the possibility of for-

est res. Do not operate the chain saw with
a loose or defective mufer. Do not remove

the spark arrestor screen.

15. Operate the chain saw only in well-ventilated
areas.

WARNING DANGER

• During operation, the mufer or catalytic mufer and surrounding cover become hot.

• Never suspend the saw on a lanyard with the engine running.

• Always use the saw from the right-hand side of your body – NEVER from the left side.

• Always wear proper safety clothing to protect your lower body from sharp saw chain and

hot mufer.

• Always keep exhaust area clear of ammable debris during transportation or when storing,

otherwise serious property damage or personal injury may result.

WARNING DANGER

Using improper replacement components or removing safety devices may result in serious or fatal injury.

WARNING

IMPROPER CLUTCH COVER ASSEMBLY CAN RE­SULT IN SERIOUS INJURY, AND WILL CAUSE SE­VERE SAW DAMAGE IF UNIT IS STARTED. NEVER
START OR OPERATE SAW IF BRAKE BAND IS NOT
IN PLACE ON CLUTCH DRUM. ALWAYS CHECK
CHAIN BRAKE OPERATION AFTER REPLACING
COVER. DO NOT USE SAW IF CHAIN BRAKE DOES
NOT FUNCTION PROPERLY.

WARNING DANGER

Saw Chain is sharp! Always wear gloves when handling
assembly, otherwise serious personal injury may result.

NOTE

Move chain brake lever fully rearward to remove or install
clutch cover to saw.

IMPORTANT

Always loosen guide bar nuts before turning chain
tension adjuster, otherwise clutch cover and tensioner
will be damaged.

1. Remove spark plug lead.

2. Remove two guide bar nuts and remove guide bar cover.

Turn tension adjustment screw counterclockwise 2 to 3
turns if bar and chain are installed.

3. Remove guide bar and saw chain if necessary.

NOTE: See “MAINTENANCE AND CARE” instructions
for guide bar, sprocket, and saw chain maintenance.

4. Mount guide bar (G) on studs, and slide toward sprocket

to make saw chain installation easier.

5. Install saw chain (H) as shown, with cutters on top of

guide bar facing forward.

6. Align holes of clutch cover (J) with guide bar studs,

and tensioner pin (I) with lower guide bar adjuster hole.

7. Turn saw over and check brake band for correct posi­tion around clutch drum. If brake band is not in place
