GENERAL SAFETy RULES  
squeeze the throttle trigger and maintain a  
steady cutting speed.  
WARNING:  
Read and understand all instructions. Failure  
to follow all instructions listed below, may result  
in electric shock, fire and/or serious personal  
injury.  
• Do ot overreach or cut above chest height.  
• Follow the ma ufacturer’s sharpe i g a d  
maintenance instructions for the saw chain.  
• O ly use replaceme t bars a d chai s  
specified by the manufacturer or the  
equivalent.  
READ ALL INSTRUCTIONS  
Know your tool. Read the operator’s manual  
carefully. Learn the saw’s applications and  
limitations as well as the specific potential  
hazards related to this tool.  
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.  
Kickback may occur when the nose 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 toward 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. Do not rely exclusively  
upon the safety devices built into the saw. As a  
chain saw user, you should take several steps  
to keep your cutting jobs free from accident or  
injury.  
Do not operate a chain saw when you are  
fatigued. Fatigue causes carelessness. Be more  
cautious before rest periods and towards the  
end of your shift. Never operate a chain saw  
when you are tired or under the influence of  
medication, drugs, or alcohol.  
Use safety footwear. Wear snug-fitting  
clothing, protective gloves, and eye, hearing,  
and head protection devices.  
Heavy protective clothing may increase  
operator fatigue, which could lead to  
heat stroke. During weather that is hot and  
humid, heavy work should be scheduled for  
early morning or late afternoon hours when  
temperatures are cooler.  
• With a basic u dersta di g of kickback,  
you can reduce or eliminate the element  
of surprise. Sudden surprise contributes to  
accidents.  
Do not stand on any unstable surface while  
using the chain saw, that includes ladders,  
scaffolds, trees, etc.  
• Keep a good firm grip o the saw with both  
hands when the engine is running. Place  
your right hand on the rear handle and  
your left hand on the front handle with your  
thumbs and fingers encircling the chain saw  
handles. A firm grip together with a stiff left  
arm will help you maintain control of the saw  
if kickback occurs.  
Use caution when handling fuel. Move the  
chain saw at least 30 feet from the fueling point  
before starting the engine.  
Do not allow other persons to be near the  
chain saw when starting or cutting with the  
chain saw. Keep bysta ders a d a imals out  
of the work area.  
• Make sure that the area i 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 start cutting until you have a clear  
work area, secure footing, and a planned  
retreat path from the falling tree.  
Keep all parts of your body away from the  
saw chain when the engine is running.  
Always carry the chain saw with the engine  
stopped and the chain brake engaged, the

with the engine running at full speed. Fully

in the instruction manual and all maintenance,  
should be performed by competent chain saw  
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 subsequently  
could cause the flywheel to burst.)  
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.  
Always have a fire extinguisher available  
Shut off the engine before setting the chain

kickback chains specified for the saw.  
Do not adapt the powerhead to a bow guide  
or use it to power any attachments or devices  
not listed for the saw.  
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.  
The gas powered saw (or electrically  
powered saw) is classified by CSA as a  
Class 1C (or Class 2C) saw. It is intended for  
infrequent use by homeowners, cottagers, and  
campers, and for such general applications as  
clearing, pruning, cutting firewood, etc. It is not  
intended for prolonged use. Prolonged periods  
of operation can cause circulatory problems in  
the user’s hands due to vibration. For such use,  
it may be appropriate to use a saw having an  
anti-vibration feature.  
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.  
Keep the handles dry, clean, and free of oil or  
fuel mixture.  
Beware of carbon monoxide poisoning.  
Operate the chain saw only in well-ventilated  
areas.  
Save these instructions. Refer to them  
frequently and use to instruct other users. If you  
loan someone this product, loan them these  
instructions also.  
Do not operate a chain saw in a tree unless  
you have been specifically trained to do so.  
Do not cut from a ladder; this is extremely  
dangerous.  
SPECIFIC SAFETy RULES  
away from the muffler. Serious burns may occur  
if contact is made with the muffler.  
WARNING:  
Always hold the chain saw with both hands  
when the engine is running. Use a firm grip  
with thumbs and fingers encircling the chain  
saw handles.  
The warnings, labels, and instructions found  
in this section of the operator’s manual are for  
your safety. Failure to follow all instructions may  
result in serious personal injury.  
Never let anyone use the chain saw who  
has not received adequate instructions in its  
proper use. This applies to rentals as well as  
privately owned saws.  
Do not cut vines and/or small underbrush (a  
diameter of less than 3 in.).  
Muffler surfaces are very hot during and after  
operation of the chain saw; keep all body parts

Before you start the engine, make sure the  
Refer to Adjusting the Carburetor in the  
Maintenance section of this manual. If the saw  
chain still moves at idle speed after adjustment  
has been made, contact an authorized service  
center for adjustment and discontinue use until  
the repair is made.  
saw chain is not contacting any object.  
Wear snug-fitting clothing. Always wear  
heavy, long pants, boots, and gloves. Do not  
wear jewelry, short pants, sandals, or go bare-  
foot. Do not wear loose fitting clothing, which  
could be drawn into the engine or catch the  
chain or underbrush. Wear overalls, jeans, or  
chaps made of cut-resistant material or ones  
that contain cut-resistant inserts. Secure hair  
so that it is above shoulder level.  
REFUELING (DO NOT SMOKE!)  
To reduce the risk of fire and burn injury,  
handle fuel with care. It is highly flammable.  
Mix and store fuel in a container approved for  
gasoline.  
Wear non-slip safety footwear and heavy-  
duty gloves to improve your grip and to protect  
your hands.  
Mix fuel outdoors where there are no sparks  
or flames.  
Select bare ground, stop the engine, and  
allow it to cool before refueling.  
Loosen the fuel cap slowly to release pres-  
sure and to keep fuel from escaping around the  
cap.  
Wear eye protection which is marked to  
comply with ANSI z87.1, as well as hearing  
and head protection, when operating this  
equipment.  
Keep bystanders and animals out of the work  
area. Do not allow other persons to be nearby  
during starting or cutting with the chain saw.  
Tighten the fuel cap securely after refueling.  
Wipe spilled fuel from the unit. Move 30  
feet away from refueling site before starting  
engine.  
NOTE: The size of the work area depends on the  
job being performed as well as the size tree or  
workpiece involved. For example, felling a tree  
requires a larger work area than making other  
cuts (i.e., bucking cuts, etc.).  
Never attempt to burn off spilled fuel under  
any circumstances.  
Keep SAFE-T-TIP® anti-kickback nose guard  
properly mounted on the guide bar to prevent  
rotational kickback.  
KICKBACK  
Kickback is a dangerous reaction that can  
lead to serious injury. Do not rely only on the  
safety devices provided with the saw. As a  
chain saw user, you must take special safety  
precautions to help keep your cutting jobs free  
from accident or injury. See the General Safety  
Rules and Operation sections of this manual  
for added information on kickback and how to  
avoid serious personal injury.  
Follow the sharpening and maintenance  
instructions for the saw chain.  
Never operate a chain saw that is damaged,  
improperly adjusted, or is not completely  
and securely assembled. Be sure that the saw  
chain stops moving when the throttle control  
trigger is released. If the saw chain moves at  
idle speed, the carburetor may need adjusting.
