Stihl MS 440 Instruction Manual page 12

!
Warning!
To reduce the risk of fire or burn injury,
keep the area around the muffler clean.
Remove all debris such as pine needles,
branches or leaves.
!
Warning!
An improperly mounted or damaged
cylinder housing or a damaged/
deformed muffler shell may interfere
with the cooling effect of the catalytic
converter. To reduce the risk of fire or
burn injury, do not continue work with a
damaged or improperly mounted
cylinder housing or a damaged/
deformed muffler shell. Your catalytic
converter is furnished with screens
designed to reduce the risk of fire from
the emission of hot particles. Due to the
heat from the catalytic reaction, these
screens will normally stay clean and
need no service or maintenance. If you
experience loss of performance and you
suspect a clogged screen, have your
muffler maintained by a STIHL Servicing
Dealer.
Working Conditions
Operate the chainsaw under good
visibility and daylight conditions only.
MS 440, MS 440 W, MS 440 C
!
Warning!
Your chainsaw produces
poisonous exhaust fumes
as soon as the
combustible engine is
running. These gases
(e.g. carbon monoxide)
may be colorless and odorless. To
reduce the risk of serious or fatal injury
from breathing toxic fumes, never run
the chainsaw indoors or in poorly
ventilated locations. Ensure proper
ventilation when working in trenches or
other confined areas.
!
Warning!
Use of this product (including sharpen-
ing the saw chain) can generate dust,
mists and fumes containing chemicals
known to cause respiratory disease,
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. Control
dust (such as sawdust), mists (such as
oil mist from chain lubrication) and
fumes at the source where possible.
English / USA
In this regard use good work practices
and follow the recommendations of
OSHA / NIOSH and occupational and
trade associations. When the inhalation
of toxic dust, mists and fumes cannot be
eliminated, the operator and any
bystanders should always wear a
respirator approved by NIOSH / MSHA
for the type substance at issue.
!
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 cut or disturb asbestos,
asbestos containing products (e.g.
asbestos containing drywall or other
construction products), or products such
as pipes which are wrapped or covered
with asbestos insulation. If you have any
reason to believe that you might be
cutting asbestos, immediately contact
your employer or a local OSHA
representative.
