Reduced-Kickback
Guide Bar,
designed with a small radius tip which
reduces the size of the kickback danger
zone on bar tip. A reduced - kickback
gduide bar is one which has been
emonstrated to significantly reduce the
number and seriousness of kickbacks
when tested in accordance with safety
requirements for electric chain saws.
• Low-Kickback
Chain, designed with a
contoured depth gauge and guard link
which deflect kickback force and allow
wood to gradually ride into the cutter. A
low-kickback chain is a chain which has
met kickback performance
requirements
of ANSI B175.1-2012.
• Do not operate
chain saw while in
a tree, on a ladder, on a scaffold, or
from any unstable
surface.
• Hold tool by insulated gripping
surfaces when performing
an
operation
where the cutting
tool may
contact
hidden wiring.
Contact with a
"live" wire wilt make exposed metal parts
of the tool "live" and shock the operator.
• Do not attempt operations
beyond
your capacity
or experience.
Read
thoroughly
and understand completely all
instructions in this manual.
• Before you start chain saw, make sure
saw chain is not contacting any object.
Do not operate
a chain saw with one
hand! Serious
injury to the operator,
helpers,
or bystanders
may result
from one handed operation.
A chain
saw is intended for two-handed use only.
• Keep. the handles dry, clean, and free
of oil or grease.
Do not allow dirt, debris, or sawdust to
build up on the motor or outside air vents.
. Stop the chain saw before setting it down.
Do not cut vines and/or small under brush.
• 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.
z_WARNING:
Some dust created by
power sanding, sawing, grinding, drilling,
and other construction activities contains
chemicals known to the State of California
to cause cancer, birth defects or other
reproductive harm. Some examples of these
chemicals are:
lead from lead-based paints,
crystalline silica from bricks and
cement and other masonry products, and
• arsenic and chromium from
chemically-treated
lumber.
Your risk from these exposures varies,
depending on how often you do this type
of work. To reduce your exposure to these
chemicals:
work in a well ventilated area,
and work with approved safety equipment,
such as those dust masks that are specially
designed to filter out microscopic particles.
• Avoid prolonged contact with dust
from power sanding, sawing, grinding,
drilling,
and other construction
activities.
Wear protective clothing
and wash exposed
areas with soap
and water. Allowing dust to get into
your mouth, eyes, or lay on the skin may
promote absorption of harmful chemicals.
2_WARNING:
Useof
this tool
can
generate
and/or disburse
dust, which
may cause serious
and permanent
respiratory
or other injury. Always use
NIOSH/OSHA approved respiratory
protection appropriate for the dust
exposure. Direct particles away from face
and body.
