KICKBACK  may  occur  when  the  NOSE  or  TIP  of  the  guide  bar  touches  an  object,  or  when 
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 toward the operator. 
PINCHING  the  saw  chain  along  the  BOTTOM  of  the  guide  bar  may  PULL  the  saw  forward 
away from the operator. 
PINCHING  the  saw  chain  along  the  TOP  of  the  guide  bar  may  PUSH  the  guide  bar  rapidly 
back toward the operator. 
Any of these reactions may cause you to lose control of the saw, which could result in serious 
personal injury. 

 

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

 

Keep a good firm 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 firm grip with thumbs 
and fingers encircling the chain saw handles. A firm grip will help you reduce kickback and 
maintain control of th

e saw. Don’t let go. 

 

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. 

 

Cut at high engine speeds. 

 

Do not overreach or cut above shoulder height. 

 

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

 

Only use replacement bars and chains specified by the manufacturer or the equivalent. 

NOTE:  Low-kickback  saw  chain  is  a  chain  that  has  met  the  kickback 
performance. 

WARNING: Kickback can lead to dangerous loss of control of the chain saw 
and  result  in  serious  or  fatal  injury  to  the  saw  operator  or  to  anyone 
standing close by. Always be alert.  Rotational kickback and pinch-kickback 
are  major  chain  saw  operational  dangers  and  the  leading  cause  of  most 
accidents. 

Beware of:

ASSEMBLY 

Note:  described  actions  below  may  vary  slightly  depending  on  model  you 
purchased.
