Engine Running Behavior - Stihl FS 510 C-M Manual De Instrucciones

English
Check electrode gap (A) and
N
readjust if necessary – see
"Specifications".
Use only resistor type spark plugs of
N
the approved range.
Rectify problems which have caused
fouling of spark plug:
Too much oil in fuel mix.
N
Dirty air filter.
N
Unfavorable running conditions,
N
e.g. operating at part load.
Fit a new spark plug after approx. 100
operating hours or earlier if the
electrodes are badly eroded.
WARNING
To reduce the risk of fire and burn injury,
use only spark plugs authorized by
STIHL. Always press spark plug boot (2)
snugly onto spark plug terminal (1) of the
proper size. (Note: If terminal has
38
detachable SAE adapter nut, it must be
attached.) A loose connection between
spark plug boot and ignition wire
connector in the boot may create arcing
that could ignite combustible fumes and
cause a fire.
Installing the Spark Plug
Screw the spark plug into the N
cylinder.
Press the spark plug boot firmly
N
onto the spark plug.
Fit the cap (1) on the shroud from
N
the rear and push the lug (2) into the
opening (3) in the shroud at the
same time.
Swing the cap forwards onto the
N
shroud, insert and tighten down the
1
screw (4) firmly.

Engine Running Behavior

If engine running behavior is still
unsatisfactory after servicing the air filter
and adjusting the throttle cable, the
cause may be the muffler.
Have the muffler checked by a servicing
dealer for contamination
(carbonization).
STIHL recommends that you have
servicing and repair work carried out
exclusively by an authorized STIHL
servicing dealer.
