- Check chain tension and correct as
necessary.
- Check air filter and clean if
necessary.
- Start the saw - warm up the engine.
- Adjust idle speed correctly (chain
must not rotate).
Turn high speed screw (H) clockwise
for leaner mixture at high altitudes or
counterclockwise for richer mixture at
sea level.
Turn screws very slowly and carefully
- even slight adjustments produce a
noticeable change in engine running
behavior.
Note the following when making
corrections to high speed screw:
The setting of the high speed screw
(H) affects the maximum off-load
engine speed. If the setting is too lean,
the maximum permissible engine
speed will be exceeded and increase
the risk of engine damage.
STIHL 019 T
Adjusting idle speed
A correction at the low speed screw (L)
usually necessitates a change in the
setting of the idle speed screw (LA).
Engine stops while idling:
Check standard setting
Turn idle speed stop screw (LA)
clockwise until the chain begins
to run - then turn it back one half turn.
Chain runs while engine is idling:
Check standard setting
Turn the idle speed stop screw (LA)
counterclockwise until the chain stops
running - and then turn it about another
half turn in the same direction.
Erratic idling behavior, poor
acceleration -
even though low speed screw is one
turn open
Idle setting too lean. Turn the low
speed screw (L) counterclockwise until
the engine runs and accelerates
smoothly.
