Idle Speed Adjustment; High Altitude Operation Of Your Outboard Motor - Suzuki DF4 Manuel Du Propriétaire

IDLE SPEED ADJUSTMENT

The idle speed of your outboard motor has
been set by your dealer. If it is necessary to
adjust the idle speed, use the following proce-
dure:
1. Warm up the engine for about 5 minutes.
2. Make sure that the motor is in "NEUTRAL"
and the throttle control grip is fully closed.
3. Turn the idle adjustment screw A clockwise
to increase idle speed or counterclockwise
to decrease idle speed.

HIGH ALTITUDE
OPERATION OF YOUR
OUTBOARD MOTOR
Your outboard motor is equipped with a carbu-
retor that is designed for proper engine opera-
tion at various altitudes up to 5000 feet (1500
meters) elevation. If you operate your outboard
motor at higher elevations, the change in air
pressure may affect the standard carburetor air-
fuel ratio and could make the engine run too
rich. This could decrease engine performance,
increase fuel consumption, cause difficult warm
starting, and may cause an increase in exhaust
gas emissions.
If you always operate your outboard motor at
altitudes above 5000 feet (1500 meters), an
alternative carburetor jetting specification is
available that will adjust the air-fuel ratio to
adjust for the change in air pressure resulting
from high-altitude operation. These parts are
available from Authorized Suzuki Marine Deal-
ers and are designed for correct operation in
your motor. If you need to apply these parts to
your outboard motor, Suzuki recommends that
you have them installed by an Authorized
)
–1
Suzuki Marine Dealer, or a qualified service
professional.
If you operate an outboard motor at low
altitude (below 5000 feet (1500 meters))
when the engine has been modified for
high-altitude operation, the engine could
be damaged from overheating, or there
could be excessive exhaust gas emis-
sions.
Be sure to reinstall standard-specifica-
tion jetting in any outboard that has been
modified for high-altitude operation prior
to operating the outboard at low altitude
(below 5000 feet (1500 meters)).
