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 position, as you do not
have control of the engine speed.
In the event of an emergency, switch off
the engine immediately – move the slide
control / stop switch to 0 or STOP.
WARNING
Always stop the engine before putting a
chain saw down.
WARNING
The saw chain continues to move for a
short period after the throttle trigger is
released (flywheel effect).
Accelerating the engine while the saw
chain is blocked increases the load and
will cause the clutch to slip continuously.
This may occur if the throttle is
depressed for more than a few seconds
when the chain is pinched in the cut or
the chain brake is engaged. It can result
in overheating and damage to important
components (e.g. clutch, polymer
housing components) – which can then
increase the risk of injury, e.g., from the
saw chain moving while the engine is
idling.
WARNING
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. From time to
time, the catcher may be damaged or
removed. To reduce the risk of personal
injury, do not operate a chain saw with a
damaged or missing chain catcher.
WARNING
Inspect anti-vibration elements
periodically. Replace damaged, broken
or excessively worn anti-vibration
elements immediately, since they may
result in loss of control of the saw. A
"sponginess" in the feel of the saw,
increased vibration or increased
"bottoming" during normal operation
may indicate damage, breakage or
excessive wear. Anti-vibration elements
should always be replaced in sets. If you
have any questions as to whether the
anti-vibration elements should be
replaced, consult your STIHL servicing
dealer.
WARNING
Your saw is not designed for prying or
shoveling away limbs, roots or other
objects. Such use could damage the
cutting attachment or AV system.
WARNING
When sawing, make sure that the saw
chain does not touch any foreign
materials such as rocks, fences, nails
and the like. Such objects may be flung
off, damage the saw chain or cause the
saw to kickback
WARNING
Never modify your muffler. Any
modification could cause an increase in
heat radiation, sparks or sound level,
thereby increasing the risk of fire, burn
injury or hearing loss. You may also
permanently damage the engine. Have
your muffler serviced and repaired by
your STIHL servicing dealer only.
WARNING
The muffler and other parts of the engine
(e.g. fins of the cylinder, spark plug)
become hot during operation and remain
