kickback and are recommended. Your saw has a
low kickback chain and bar as original
equipment. Repairs on a chain brake should be
made by an authorized servicing dealer. Take
your unit to the place of
purchase if purchased from a servicing dealer, or
to the nearest authorized service dealer.
WARNING: Computed kickback angle
(CKA) listed on your saw and listed in
the CKA table below represents angle of
kickback your bar and chain combinations
will have when tested in accordance with CSA
(Canadian Standards Association) and ANSI
standards. When purchasing replacement bar
and chain, considerations should be given
to the lower CKA values. Lower CKA values
represent safer angles to the user, higher
values indicate more angle and higher kick
energies. Computed angles represented
indicate total energy and angle associated
without activation of the chain brake during
kickback. Activated angle represents chain
stopping time relative to activation angle of
chain break and resulting kick angle of saw.
In all cases lower CKA values represent a
safer operating environment for the user. The
following guide bar and chain combinations
meet kickback requirements of CSA Standards
Z62.1, Z62.3, & ANSI B175.1 when used on
saws listed in this manual. Use of bar and
chain combinations other than those listed is
not recommended and may not meet the CKA
requirements per standard.
WARNING: Do not mount a bow guide on
any Efco chainsaw. The risk of kickback
is increased with a bow guide because of the
increased kickback contact area.

WARNING: The computer derived angles
of par. 5.11 of ANSI B 175.1 – 2000 may
bear no relationship to actual kickback bar
rotation angles that may occur in real life
cutting situations.
In addition, features designed to reduce
kickback injuries may lose some of their
effectiveness when they are no longer in their
original condition, especially if they have
been improperly maintained.
Compliance with par. 5.11 of ANSI B 175.1 –
2000 does not automatically mean that in a
real life kickback the bar and chain will rotate
at most 45°.
Precautions to Reduce Vibration Risk
· The chain saw is provided with anti-vibration
(AV) system; never alter or modify it.
· Wear gloves and keep your hands warm.
· 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.
· Maintain a firm grip at all times, but do not
squeeze the handles with constant, excessive
pressures, take frequent breaks. All the above
mentioned precautions do not guarantee that
you will not sustain whitefinger disease or
carpal tunnel syndrome. Therefore, continual
and regular users should monitor closely the
condition of their hands and fingers. If any of
the above symptoms appear, seek medical
advice immediately.
Maintenance Precaution
WARNING: Never operate a chain saw that
is damaged, improperly adjusted, or is
