6 IMPORTANT SAFETY INSTRUCTIONS
￭ Your chain saw is a one-person machine.
– Do not allow other persons in the general work area.
– Switch off the motor immediately if you are
approached.
￭ To reduce the risk of injury to bystanders and
unauthorized users:
– Never leave the chain saw unattended when it is
connected to the power supply.
– Switch off the chain saw, engage the chain brake
and disconnect from the power supply during work
breaks and any other time the chain saw is not in
use.
￭ Sparks generated from the operation of the chain saw may
be capable of igniting combustible gases, liquids, vapors,
dusts or other combustible materials and substances. To
reduce the risk of fire and explosion:
– Never operate the chain saw in a location where
combustible gases, liquids, vapors, dusts or other
combustible materials and substances are present.
– Read and follow recommendations issued by
government authorities (e.g., OSHA; for Canada:
CCOHS) for identifying and avoiding the hazards of
combustible gases, liquids, vapors, dusts or other
combustible materials and substances.
￭ Use of this chain saw (including sharpening the saw
chain) can generate dust, oil mist and other substances
containing chemicals known to cause respiratory
problems, cancer, birth defects and other reproductive
harm.
– Consult governmental agencies such as EPA,
OSHA, CARB and NIOSH (for Canada: ECCC,
CCOHS and PHAC) and other authoritative sources
on hazardous materials if you are unfamiliar with the
risks associated with the particular substances you
are cutting or with which you are working.
￭ 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 or other airborne contaminants,
especially those with a smaller particle size, may cause
0458-729-8621-A
respiratory or other illnesses. This includes wood dust,
especially from hardwoods, but also from some softwoods
such as Western Red Cedar.
– Control dust (such as saw dust) and mists (such as
oil mist from chain lubrication) at the source where
possible.
– Always work with a properly sharpened saw chain,
which produces wood chips rather than fine dust.
– To the extent possible, operate the chain saw so that
the wind or operating process directs any dust, mist
or other particulate matter raised by the chain saw
away from the operator.
– When respirable dust or other particulate matter
cannot be kept at or near background levels, always
wear an approved and properly rated respirator and
follow the recommendations of governmental
authorities (e.g., OSHA/NIOSH/MSHA; for Canada:
CCOHS/PHAC/MSHA) and occupational and trade
associations.
￭ If the vegetation being cut or the surrounding ground is
coated with a chemical substance, such as pesticide or
herbicide:
– Read and follow the instructions and warnings that
accompanied the substance coating the vegetation
or surrounding ground.
￭ Breathing asbestos dust is dangerous and can cause
severe or fatal injury, respiratory illness or cancer,
including mesothelioma. The use and disposal of
asbestos-containing products is strictly regulated by
OSHA and the EPA (for Canada: CCOHS and ECCC).
– Do not use your chain saw to cut or disturb asbestos
or asbestos-containing products.
– Stop work immediately and contact the relevant
state and local authorities and/or EPA (for Canada:
ECCC), your employer or local OSHA (for Canada:
CCOHS) representative if you have reason to
believe that you might be disturbing asbestos.
