RULES FOR SAFE OPERATION  
• Do not operate a chain saw that is damaged,  
KICKBACK SAFETY PRECAUTIONS  
improperly adjusted, or not completely and securely  
assembled. Be sure that the saw’s chain stops moving  
when the throttle control trigger is released.  
KICKBACK may  
WARNING:  
occur when the nose  
• Shut off the engine before setting the chain saw down.  
or tip of the guide bar touches an object, or  
when the 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  
towards the operator. Pinching the saw chain  
along the top of the guide bar may push the  
guide bar rapidly back toward the operator.  
Either of these reactions may cause you to  
lose control of the saw, which could result in  
serious personal injury.  
• Use extreme caution when cutting small-sized brush  
and saplings because slender material may catch the  
chain saw and whip towards you or pull you off  
balance.  
• When cutting a limb that is under tension, be alert for  
springback so that you will not be struck when the  
tension in the wood fibers is released  
• Do not cut through nails, rods in the tree, railroad ties  
or pallates. Inspect a tree that you are going to cut for  
foreign objects that could cause injury or damage to  
your chain saw.  
Do not rely exclusively upon the safety  
devices built into your saw. As a chain saw  
user, you should take several steps to keep  
your cutting jobs free from accident or injury.  
• After striking a foreign object, stop the engine and  
thoroughly inspect for damage. Repair as necessary.  
• With a basic understanding of kickback, you can  
reduce or eliminate the element of surprise. Sudden  
surprise contributes to accidents. Be alert to the  
potential for kickback at all times.  
• Keep the handles dry, clean and free of the oil/fuel  
mixture  
• We do not recommend using the chain saw in a tree or  
on a ladder.  
• 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 the saw. Don’t let go.  
• All chain saw service, other that the items listed in this  
instruction manual maintenance instructions, should be  
performed by competent chain saw service personnel.  
• Use the right tool. Only use this chain saw for its  
intended purpose, to cut wood.  
• 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  
that could be hit while you are operating the saw.  
• Do not overreach. Always keep proper footing and  
balance.  
• Always hold the unit with both hands when operating.  
Keep a firm grip on all handles or grips.  
• Always cut with the engine running at full speed. Fully  
squeeze the throttle trigger and maintain a steady  
cutting speed.  
• Apply chain brake prior to any repositioning of the  
operator in the cutting area. As an additional safety  
precaution, apply the chain brake prior to setting down  
the saw.  
• Use only the correct original equipment manufacturer  
replacement bars, chains and other parts and  
accessories. These are available from your authorized  
service dealer. Use of any unauthorized parts or  
accessories could lead to serious injury to the user, or  
damage to the unit, and will void your warranty.  
• Never touch the chain or attempt to service the saw  
while the engine is running. Make sure all moving parts  
have stopped. Allow the chain saw to cool, as the  
chain can be hot.  
• Check the bar and chain at frequent intervals for  
proper adjustment. Make sure the bar and chain are  
properly tightened and sharpened. Visually inspect for  
damage. Repair any damage before restarting or  
operating the chain saw.  
• Follow the manufacturer’s sharpening and  
maintenance instructions for the saw chain.  
• Use only the replacement guide bars and low kickback  
chains specified for your saw to avoid injury.

flammable, and its  
WARNING:  
vapors can explode if ignited. Take the  
following precautions:  
• Never carry out operations or repairs on your own that  
are other than routine maintenance. For information,  
contact specialized and authorized workshops only.  
• Store fuel only in containers specifically designed and  
approved for the storage of such materials.  
• If your chain saw is no longer usable, dispose of it  
properly without damaging the environment by

in the tank.  
• Use caution when felling a tree. Make sure you have  
planned an escape path when felling, and keep all  
bystanders away.  
• Add fuel in a clean, well-ventilated outdoor area where  
there are no sparks or flames. Slowly remove the fuel  
cap only after stopping engine. Do not smoke while  
fueling or mixing fuel. Wipe up any spilled fuel from the  
unit immediately.  
• Be alert; stop the machine if anyone enters the cutting  
area, which is usually 3 to 4 feet around the operator.  
• Use caution when working in a crew to avoid injury to  
a fellow worker who may enter the cutting area.  
• Avoid creating a source of ignition for spilled fuel. Do  
not start the engine until fuel vapors dissipate.  
• Only loan your saw to experienced users who are  
completely familiar with saw operation and correct  
use. Give other users this manual, which they should  
read before using the saw. Provide them the operating  
instructions.  
• Move the unit at least 30 feet (9.1 m) from the fueling  
source and site before starting the engine. Do not  
smoke. Keep sparks and open flames away from the  
area while adding fuel or operating the unit.  
• Shut off the engine before setting down the saw. Do  
not leave the engine running unattended.  
• Never store the unit, with fuel in the tank, inside a  
building where fumes may reach an open flame or  
spark.  
SAVE THESE  
INSTRUCTIONS  
• Allow the engine to cool before storing or transporting  
the chain saw over long distances. For example, let  
the engine cool before placing the chain saw in an  
automobile. Also, be sure to secure the unit while

OIL AND FUEL INFORMATION  
Thoroughly mix the proper ratio of 2-cycle engine oil  
OIL AND FUEL MIXING INSTRUCTIONS  
with unleaded gasoline in a separate fuel can. Use a 40:1  
fuel/oil ratio. Do not mix them directly in the engine fuel  
tank. See the table below for specific gas and oil mixing  
ratios.  
Old and/or improperly mixed fuel are the main reasons  
for the unit not running properly. Be sure to use fresh,  
clean unleaded fuel. Follow the instructions carefully for  
the proper fuel/oil mixture.  
NOTE: One gallon (3.8 liters) of unleaded gasoline mixed  
with one 3.2 oz. (95 ml.) bottle of  
Definition of Blended Fuels  
2-cycle oil makes a 40:1 fuel/oil ratio.  
Today's fuels are often a blend of gasoline and  
oxygenates such as ethanol, methanol, or MTBE (ether).  
Alcohol-blended fuel absorbs water. As little as 1%  
water in the fuel can make fuel and oil separate. It forms  
acids when stored. When using alcohol-blended fuel,  
use fresh fuel (less than 60 days old).
