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 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.
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.
