Stihl MS 192 Instruction Manual page 15

Vibrations
Prolonged use of the power tool may
result in vibration-induced circulation
problems in the hands (whitefinger
disease).
No general recommendation can be
given for the length of usage because it
depends on several factors.
The period of usage is prolonged by:
Hand protection (wearing warm
–
gloves)
Work breaks
–
The period of usage is shortened by:
Any personal tendency to suffer
–
from poor circulation (symptoms:
frequently cold fingers, tingling
sensations).
Low outside temperatures.
–
The force with which the handles
–
are held (a tight grip restricts
circulation).
Continual and regular users should
monitor closely the condition of their
hands and fingers. If any of the above
symptoms appear (e.g. tingling
sensation in fingers), seek medical
advice.
Maintenance and Repairs
Service the machine regularly. Do not
attempt any maintenance or repair work
not described in the instruction manual.
Have all other work performed by a
servicing dealer.
MS 192 C
STIHL recommends that you have
servicing and repair work carried out
exclusively by an authorized STIHL
servicing dealer. STIHL dealers are
regularly given the opportunity to attend
training courses and are supplied with
the necessary technical information.
Only use high-quality replacement parts
in order to avoid the risk of accidents
and damage to the machine. If you have
any questions in this respect, consult a
servicing dealer.
STIHL recommends the use of genuine
STIHL replacement parts. They are
specifically designed to match your
model and meet your performance
requirements.
To reduce the risk of injury, always shut
off the engine before carrying out any
maintenance or repairs or cleaning the
machine. – Exception: Carburetor and
idle speed adjustments.
Do not turn the engine over on the
starter with the spark plug boot or spark
plug removed unless the slide control /
stop switch is on STOP or 0 since there
is otherwise a risk of fire from
uncontained sparking.
To reduce the risk of fire, do not service
or store your machine near open flames.
Check the fuel filler cap for leaks at
regular intervals.
Use only a spark plug of the type
approved by STIHL and make sure it is
in good condition – see "Specifications".
Inspect the ignition lead (insulation in
good condition, secure connection).
Check the condition of the muffler.
To reduce the risk of fire and damage to
hearing, do not operate your machine if
the muffler is damaged or missing. –
Do not touch a hot muffler since burn
injury will result.
Vibration behavior is influenced by the
condition of the AV elements – check the
AV elements at regular intervals.
Check the chain catcher and replace it if
damaged.
Stop the Engine
before checking chain tension.
–
before retensioning the chain.
–
before replacing the chain.
–
before rectifying problems.
–
Observe sharpening instructions – keep
the chain and guide bar in good
condition at all times for safe and correct
handling of the saw. The chain must be
properly sharpened, tensioned and well
lubricated.
Always change the chain, guide bar and
sprocket in good time.
Check condition of clutch drum
periodically.
Store fuel and chain lubricant in properly
labelled, safety-type canisters only.
When handling gasoline, avoid direct
contact with the skin and avoid inhaling
fuel vapour – health risk.
To reduce the risk of injury, shut off the
engine immediately if the chain brake
malfunctions – contact your servicing
dealer – do not use your power tool until
the problem has been rectified (see
"Chain Brake").
