  1. Do not operate a chain saw with one 

hand! Serious injury to the operator, 

helpers, or bystanders 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-fitting 

clothing and protective gloves.  

    Wear eye, hearing, and head 

protection devices.

  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 

when operating the chain saw.  

  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 muffler 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 fibers is released. 

 14. Keep the handles dry, clean, and free 

of oil or fuel mixture. 

 15. Operate the chain saw only in well 

ventilated areas. 

 16. Do not operate a chain saw in a tree 

unless you have been specifically 

trained to do so. 

 17. All chain saw service, other than 

items listed in the Instruction manual 

maintenance instructions, should 

be performed by competent service 

personnel.  

 

 

 

(For example, if improper tools are 

used to remove the flywheel or if 

an improper tool is used to hold the 

flywheel in order to remove the clutch, 

structural damage to the flywheel could 

occur and could subsequently cause 

the flywheel to burst.)

 18. When transporting your chain saw, use 

the appropriate guide bar scabbard.

 19. Spark arrestor mufflers approved to 

SAE Standard J335 are standard 

on ECHO chain saws to reduce the 

possibility of forest fires. 

 

Do not operate the chain saw with a 

loose or defective muffler.  

 

Do not remove the spark arrestor 

screen.
