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 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 a respirator that is approved by NIOSH and
rated for worksite-specific conditions. Follow the
recommendations of governmental authorities (e.g.,
OSHA/NIOSH) 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 illness, respiratory illness or cancer,
including mesothelioma. The use and disposal of
asbestos-containing products is strictly regulated by
OSHA and the EPA.
– 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, your
employer or local OSHA representative if you have
reason to believe that you might be disturbing
asbestos.

your STIHL chain saw.
6.5.4 Operating Instructions
WARNING
￭ To reduce the risk of severe personal injuries from
unintentional starting:
– Never touch a chain with your hand or any part of
your body when the battery is inserted, even when
the chain is not rotating.
– Avoid contacting the trigger switch lockout and
trigger switch when grasping the control handle of
the chain saw.
￭ The chain continues to move for a short period after the
trigger switch is fully released.
– Wait for the chain to stop and engage the chain
brake before walking with the chain saw or putting it
down.
￭ In the event of an emergency:
– Switch off the motor immediately, engage the chain
brake and remove the battery.
￭ Your chain saw is equipped with a chain catcher. It is
designed to reduce the risk of personal injury in the event
of a thrown or broken chain.
– Never operate the chain saw with a damaged or
missing chain catcher.
￭ Contacting foreign objects while sawing might cause the
chain to break or be thrown, or cause the chain saw to
propel dangerous debris or kick back in the direction of the
operator. To reduce the risk of severe or fatal personal
injury caused by contact with foreign objects:
– Inspect the tree, log or branch before cutting.
– Remove any foreign objects to ensure that the wood
is free of materials such as nails, spikes, cables, or
wires.
