Spark Plug - Stihl TS 700 Instruction Manual

English
14.4.2 Abrasive cutting wheel rotates when
idling
► Turn the idle speed adjusting screw (LA) coun‐
terclockwise until the abrasive cutting wheel
stops rotating – then give the screw 1/4 turn in
the same direction
► If the cutting wheel still rotates while idling:
Turn the idle speed screw (LA) another 1/4
turn counterclockwise
WARNING
If the abrasive cutting wheel continues to rotate
in idle even after adjustment, have the cut-off
machine checked by a servicing dealer.
14.4.3 Speed erratic when idling; poor accel‐
eration (despite adjustment to LA set‐
ting)
The idle setting is too lean.
► Turn the low speed adjusting screw (L)
approx. 1/4 turn counterclockwise until the
engine runs and accelerates smoothly – max.
up to the stop
14.4.4 Idle speed cannot be increased suffi‐
ciently via the idle speed adjusting
screw (LA), engine stops when chang‐
ing from part-load to idle speed
The idle setting is too rich.
► Turn low speed adjusting screw (L) approx.
1/4 turn clockwise
Whenever the low speed adjusting screw (L) has
been adjusted, it is usually also necessary to
readjust the idle speed adjusting screw (LA).
14.5 Correcting the carburetor set‐
ting for use at high altitudes
The setting may have to be marginally corrected
if engine performance is unsatisfactory at high
altitudes:
► Carry out the standard setting
► Allow engine to warm up
► Turn the high speed adjusting screw (H)
slightly clockwise (leaner) – max. up to the
stop
30
NOTICE
After descending from a high altitude, restore the
carburetor setting to the standard setting.
If you make the setting too lean it will increase
the risk of engine damage through lack of lubri‐
cation and overheating.

► If the engine is down on power, difficult to start
or runs poorly at idle speed, first check the
spark plug.
► Fit a new spark plug after about 100 operating
hours – or sooner if the electrodes are badly
eroded. Install only suppressed spark plugs of
the type approved by STIHL – see "Specifica‐
tions".
