1. For safe operation

    WARNING

This chainsaw has been especially designed for tree
maintenance and should therefore only be used by
trained operators when working on trees.

1. 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.

2. Use safety footwear, snug fitting

clothing and eye, hearing and head
protection devices.
Use the vibration-proof glove.

3. Keep the saw chain sharp and the

saw, including the AV system, well
maintained. A dull chain will increase
cutting time, and pressing a dull
chain through wood will increase the
vibrations transmitted to your hands.
A saw with loose components or with
damaged or worn AV buffers will also
tend to have higher vibration levels.

4. Always use caution when handling

fuel. Wipe up all spills and then move
the chain saw at least 3 m from the
fueling point before starting the en-
gine.

5. Eliminate all sources of sparks or

flame (i.e. smoking, open flames, or
work that can cause sparks) in the
areas where fuel is mixed, poured,
or stored.

6. Do not smoke while handling fuel or

while operating the chain saw.

7. Do not allow other persons to be near

the chain saw when starting or cut-
ting. Keep bystanders and animals
out of the work area. Children, pets
and bystanders should be a minimum
of 10 m away when you start or oper-
ate the chain saw.

8. Never start cutting until you have a

clear work area, secure footing, and
a planned retreat path from the fall-
ing tree.

9. Always hold the chain saw firmly with

both hands when the engine is run-
ning. Use a firm grip with thumb and
fingers encircling the chain saw
handles.

10. Keep all parts of your body away from

the saw chain when the engine is run-
ning.

11. Before you start the engine, make

sure the saw chain is not contacting
anything.

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, Ioose, or dam-
aged parts. Never operate a chain
saw that is damaged, improperly ad-
justed, or is not completely and se-
curely 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 Owner’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 fly-
wheel to disintegrate.)

15. Always shut off the engine before

setting it down.

16. Use extreme caution when cutting

small size brush and saplings be-
cause 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 ten-

sion, be alert for spring- back so that
you will not be struck when the ten-
sion in the wood fibers is released.

18. 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.

19. Keep the handles dry, clean and free

of oil or fuel mixture.
