 

Kickback is a dangerous reaction that can lead to serious 
injury. Kickback may occur when the moving chain con-
tacts an object at the upper portion of the tip of the guide 
bar or when the wood closes in and pinches the chain 
in the cut. Contact at the upper portion of the tip of the 
guide bar can cause the chain to dig into the object and 
stop the chain for an instant. The result is a lightning-fast, 
reverse reaction which kicks the guide bar up and back 
toward the operator. If the chain is pinched along the top 
of the guide bar, the guide bar can be driven rapidly back 
toward the operator, which can cause loss of control and 
may result in serious injury. Do not rely exclusively upon 
the safety devices built into the product. 

  With a basic understanding of kickback, you can reduce 

or  eliminate  the  element  of  surprise.  Sudden  surprise 
contributes to accidents.

 

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,  fence,  or  any  other  obstruction 
while you are operating the unit. Have a planned retreat 
path.

 

Cut only when visibility and light are adequate for you to 
see clearly.

 

Do not use on a ladder or unstable support. Always cut 
with both feet on solid ground to prevent being pulled off 
balance.

 

To protect yourself from electrocution, do not operate 
within 50 feet of overhead electrical lines.

 

Before starting the engine, make sure the chain is not 
contacting any object.

 

Always cut with the engine running at full speed. Fully 
squeeze the throttle trigger and maintain a steady cutting 
speed.

 

Do not force tool. Use the correct tool for your applica-
tion. The correct tool will do the job better and safer at 
the rate for which it is designed.

 

To protect yourself from falling branches, do not stand di-
rectly under the branch or limb being cut. This unit should 
not be held at an angle over 60° from ground level.

 

Keep the handles dry, clean, and free of oil or fuel mix-
ture.

 

Shut off the engine and make sure the cutting attachment 
has stopped before setting the unit down.

 

To prevent electrical shock or serious personal injury, do 
not use this product with any AC power head.

 

Follow the sharpening and maintenance instructions for 
the saw chain.

 

Use only the replacement guide bars and low kickback 
chains specified for the unit.

 

Operate saw in well ventilated areas. 

 

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

 

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

 

 When cutting a limb that is under tension, be alert for 
spring back sot that you will not be struck when tension 
in wood fibers are released. 

REFUELING

 

FUEL IS HIGHLY FLAMMABLE. 

Take precautions when 

using to reduce the chance of serious personal injury.

 

Store fuel in a cool, well-ventilated area, safely away from 
spark and/or flame-producing equipment 

 

Store  fuel  in  containers  specifically  designed  for  this 
purpose.

 

Only refuel outdoors and do not smoke while refueling.

 

Add fuel before starting the engine. Never remove the cap 
of the fuel tank or add fuel while the engine is running or 
when the engine is hot.

 

If fuel is spilled, do not attempt to start the engine but 
move the machine away from the area of spillage and 
avoid  creating  any  source  of  ignition  until  fuel  vapors 
have dissipated.

 

Replace all fuel tank and container caps securely.

 

If the fuel tank has to be drained, do this outdoors.
