WARNING
Your chain saw is a one-person
machine. Do not allow other persons in
the general work area, even when
starting. Stop the engine immediately if
you are approached.
WARNING
Even though bystanders should be kept
away from the running saw, never work
alone. Keep within calling distance of
others in case help is needed.

WARNING
As soon as the engine is
running, this product gen-
erates toxic exhaust
fumes containing chemi-
cals, such as unburned
hydrocarbons (including
benzene) and carbon
monoxide, that are
known to cause respira-
tory problems, cancer,
birth defects, or other
reproductive harm. Some
of the gases (e.g. carbon
monoxide) may be color-
less and odorless. To
reduce the risk of serious
or fatal injury / illness
from inhaling toxic fumes,
never run the machine
indoors or in poorly venti-
lated locations. If exhaust
fumes become concen-
trated due to insufficient
ventilation, clear obstruc-
tions from work area to
permit proper ventilation
before proceeding and /
or take frequent breaks to
allow fumes to dissipate
before they become
concentrated.
WARNING
Inhalation of certain dusts, especially
organic dusts such as mold or pollen,
can cause susceptible persons to have
an allergic or asthmatic reaction.
Substantial or repeated inhalation of
dust and other airborne contaminants, in
particular those with a smaller particle
size, may cause respiratory or other
illnesses. This includes wood dust,
especially from hardwoods, but also
from some softwoods such as Western
Red Cedar. Control dust at the source
where possible. Use good work
practices, such as always cutting with a
properly sharpened chain (which
produces wood chips rather than fine
dust) and operating the unit so that the
wind or operating process directs any
dust raised by the power tool away from
the operator. Follow the
recommendations of EPA / OSHA /
NIOSH and occupational and trade
associations with respect to dust
("particulate matter"). When the
inhalation of dust cannot be
substantially controlled, i.e., kept at or
near the ambient (background) level, the
operator and any bystanders should
wear a respirator approved by NIOSH /
MSHA for the type of dust encountered.
WARNING
Breathing asbestos dust is dangerous
and can cause severe or fatal injury,
respiratory illness or cancer. The use
and disposal of asbestos-containing
products have been strictly regulated by
OSHA and the Environmental Protection
Agency. If you have any reason to
believe that you might be cutting
asbestos, immediately contact your
employer or a local OSHA
representative.
Operating Instructions
WARNING
Do not operate your power tool using the
starting throttle lock, as you do not have
control of the engine speed.
