CUTTING INSTRUCTION

GENERAL

   CAUTION

•ReadtheECHO“CHAINSAWSAFETY

MANUAL” included with your chain saw for 

additional cutting and safety instructions. 

•Wearsuitablehearingprotectionsuchas

earmuffs or earplugs to protect against 

objectionable or uncomfortable loud noises. 

•Donotletthetipofthebartouchanything

while the engine is running.  

At cutting speed the chain is moving at a 

high rate of speed.  

Should the tip contact a limb or log while 

the chain is moving, the tip will be pushed 

upward with considerable force.  

This is known as kickback. Avoid it! 

In all circumstances the operation of the chain saw 

is a one-man job. 

It is difficult at times to take care for your own  

safety, so don’t assume the responsibility for a 

helper as well. 

After you have learned the basic techniques of 

using the saw, your best aid will be your own good 

common sense. 

The accepted way to hold the saw is to stand to the 

left of the saw with your left hand on the front  

handlebar and your right hand on the rear handle 

so you can operate the throttle trigger with your 

right index finger. 

Before attempting to fell a tree, cut some small logs 

or limbs. 

Become thoroughly familiar with the controls and 

the responses of the saw. 

Start the engine, see that it is running properly. 

Squeeze the trigger to open the throttle wide open 

and start the cut. If the chain is properly  

sharpened, the cutting should be relatively  

effortless. 

It is not necessary to press down hard to make the 

saw cut. 

Pushing the saw too hard will slow the engine and 

cutting will actually be more difficult. 

Some material may adversely affect the housings 

of your chain saw. 

(Example palm Tree Acid, fertilizer etc.) 

To avoid housing deterioration, carefully remove all 

packed sawdust around clutch and guide bar area 

and wash with water. Coat metal parts with light oil.
