Standard Setting
:
:
Carry out standard setting.
Engine stops while idling
Warm up engine for about 5
:
:
Shut off the engine.
:
Turn idle speed screw (LA) slowly
clockwise until the engine runs
smoothly – cutting blade must not
rotate.
minutes.
Mount cutting blade and clean it if
necessary (make sure it is not
damaged or warped).
:
Open the throttle wide.
At high altitude
:
:
Check the air filter and replace if
Cutting blade rotates when engine is
idling
:
Rotate the high speed screw (H)
necessary.
clockwise (leaner):
Turn high speed screw (H)
counterclockwise (max. 3/4 turn)
as far as stop.
Turn about 1/4 turn for every 1,000
meters (3,300 feet) difference in
altitude, but no further than stop.
:
Turn idle speed screw (LA) slowly
counterclockwise until cutting blade
stops rotating and then turn the
screw about another 1/2 to 1 turn in
the same direction.
:
Carefully screw the low speed
screw (L) down onto its seat. Then
open it one turn counterclockwise.
At sea level
:
Rotate the high speed screw (H)
counterclockwise (richer):
Erratic idling behavior, engine stops
even though setting of LA screw is
correct, poor acceleration
:
:
Start and warm up the engine.
Adjust idle speed with the idle speed
screw (LA) so that the cutting blade
does not rotate.
Turn about 1/4 turn for every 1,000
meters (3,300 feet) difference in
altitude, but no further than stop.
Idle setting too lean:
:
Turn low speed screw (L)
counterclockwise (about 1/4 turn)
until the engine runs and
accelerates smoothly.
It is possible that maximum engine
speed will already be reached with
the standard setting.
Fine Tuning
A slight correction of the setting of the
high speed screw (H) may be necessary
if engine power is not satisfactory when
operating at high altitude or at sea level.
Adjusting Idle Speed
Erratic idling behavior
Idle setting too rich:
It is usually necessary to change the
setting of the idle speed screw (LA)
after every correction to the low speed
screw (L).
:
Turn low speed screw (L) clockwise
(about 1/4 turn) until the engine runs
and accelerates smoothly.
:
Warm up engine for about 5
minutes.
