operation where the cutting tool may
contact hidden wiring. Contact with a
"live" wire will 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 chainsaw, make sure
saw chain is not contacting any object.
• Do not operate a chainsaw with one
hand! Serious injury to the operator,
helpers, or bystanders may result from
one handed operation. A chainsaw 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 chainsaw 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.
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.
WARNING:
Use of 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.
An extension cord must have adequate
wire size (AWG or American Wire Gauge)
for safety. The smaller the gauge number
of the wire, the greater the capacity of the
cable, that is 16 gauge has more capacity
than 18 gauge. When using more than one
extension to make up the total length, be sure
