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), switch
it off and make sure that unauthorized
persons do not use it. To do this, move
the front hand guard to ƒ and
disconnect the plug from the power
supply.
WARNING
Operate your chain saw so that it
produces a minimum of noise – do not
run motor unnecessarily and accelerate
the motor only for cutting.
WARNING
Use of this chain saw (including
sharpening the saw chain) can 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.
MSE 250 C
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) and mists (such as oil mist from
chain lubrication) 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 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. Do not use your chain saw to
cut or disturb asbestos or asbestos-
containing products. If you have any
reason to believe that you might be
cutting asbestos, immediately stop
cutting and contact your employer or a
local OSHA representative.
Operating Instructions
WARNING
Never touch a saw chain with your hand
or any part of your body when the motor
is running, even when the chain is not
rotating.
In the event of an emergency, switch off
the motor immediately, engage the
chain brake by moving the front hand
guard to ƒ and disconnect the plug
from the power supply.
WARNING
Always switch off the motor before
putting the chain saw down.
WARNING
The saw chain continues to move for a
short period after the trigger switch is
fully released.
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.
If this chain saw is subjected to
unusually high loads for which it was not
designed (e. g. heavy impact or a fall),
