CS-501P

  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-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 

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 muffler away from 
your body. When carrying a chain saw 
with the engine running, push the front 
hand guard forward to engage the 
chain brake. 

 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.
