■ Before operate the
product
1.
Before using our products, please read this
manual carefully to understand the proper use
of your unit.
2.
Never operate a chain saw when you are
fatigued, ill, or upset, or under the influence of
medication that may make you drowsy, or if
you are under the influence of alcohol or
drugs.
3.
Operate the chain saw only in well ventilated
areas. Never start or run the engine inside a
closed room or building. Exhaust fumes
contain dangerous carbon monoxide.
4.
Never cut in high wind, bad weather, when
visibility is poor or in very high or low
temperatures. Always check the tree for dead
branches which could fall during the felling
operation.
5.
Use safety footwear, snug fitting clothing and
eye, hearing and
head protection devices.

3. For safe operation
6. Always use caution when handling fuel. Wipe
up all spills and then move the chain saw at
least ten(10)feet (three(3) m) from the fueling
point before starting the engine.
7.
Eliminate all sources of sparks or flame (ie.
smoking, open flames, or work that can cause
sparks) in the areas where fuel is mixed,
poured, or stored.
Do not smoke while handling fuel or while
operating the chain saw.
8. Do not allow other persons to be near the
chain saw when starting the engine or cutting a
wood. Keep bystanders and animals out of the
work area. Children, pets, and bystanders
should be a minimum of 30feet (10m) away
when you start or operate the chain saw.
9. Never start cutting until you have a clear work
area, secure footing, and planned retreat path
from the falling tree.
10. Always hold the chain saw firmly with both
hands when the engine is running. Use a firm
grip with thumb and fingers encircling the chain
saw handles.
11. Keep all parts of your body away from the
saw chain when the engine is running. Before
you start the engine, make sure the saw chain
is not contacting anything.

3. For safe operation
12. Always carry the chain saw with the engine
stopped, the guide bar and saw chain to the
rear, and the muffler away from your body.
13. Always inspect the chain saw before each
use for worn, loose, or changed parts. 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.
14. All chain saw service, other than the items
listed in the Operator’s Manual, should be
performed by competent chain saw service
personnel. (e.g., 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 which could subsequently cause
the flywheel to disintegrate).
15. Always shut off the engine before setting it
down.
16. 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.
17. When cutting a limb that is under tension, be
alert for spring back so that you will not be
struck when the tension in the wood fibers is

9
released.
18. Keep the handles dry, clean and free of oil or
fuel mixture.
3. For safe operation
19. Guard against kickback. Kickback is the
upward motion of the guide bar which occurs
when the saw chain at the nose of the guide
bar contacts an object. Kickback can lead to
dangerous loss of control of the chain saw.
20. When transporting your chain saw, make
sure the appropriate guide bar scabbard is in
place.
