Never put pressure on the chain saw
when reaching the end of a cut. The
pressure may cause the bar and rotating
saw chain to pop out of the cut or kerf, go
out of control and strike the operator or
some other object. If the rotating saw
chain strikes some other object, a
reactive force may cause the moving
saw chain to strike the operator.
STIHL recommends that first-time users
should cut logs on a sawhorse – see
"Cutting small logs."
Working Conditions
Operate and start your chain saw only
outdoors in a well-ventilated area.
Operate it under good visibility and
daylight conditions only. Work carefully.
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 chain saw, never
work alone. Keep within calling distance
of others in case help is needed.
WARNING
To reduce the risk of injury to bystanders
and damage to property, never let your
chain saw run unattended. When it is not
in use (e. g. during a work break), shut it
off and make sure that unauthorized
persons do not use it.
WARNING
WARNING
Operate your chain saw so that it
produces a minimum of noise and
emissions – do not run engine
unnecessarily and accelerate the engine
only for cutting.
WARNING
Use of this chain saw (including
sharpening the saw chain) can also
generate dust, mist and fumes
containing chemicals that are known to
cause respiratory problems, cancer,
birth defects, or other reproductive
harm. If you are unfamiliar with the risks
associated with the particular dust, mist
or fume at issue, consult your employer,
governmental agencies such as OSHA
and NIOSH and other sources on
hazardous materials. California and
some other authorities, for instance,
have published lists of substances
known to cause cancer, reproductive
toxicity, etc.
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 (such as saw
dust), mists (such as oil mist from chain
lubrication) and engine fumes at the
source where possible. Use good work
practices, such as always cutting with a
properly sharpened saw 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 chain saw away from
the operator. Follow the
recommendations of
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.
