Type of
fl
uid:
ATF (Automatic Trans-
mission Fluid); see chapter 10.1.
5.1 Operation
ll transmissions have been submitted
to a test run before shipment:
During normal operation, the transmis-
sion should only be shifted with the
engine at idle speed.
In emergency cases it is also admis-
sible to shift at higher speeds.
The hydraulic circuit will only oper-
ate correctly if the hydraulic
fl
uid is
changed regularly, as indicated in the
maintenance schedule. (See chapter
6.1).
Visual checks for leakage should be
made from time to time.
WARNING
Work on the transmission must
only be performed with the engine
and propeller at standstill.
CAUTION
Before the
fi
rst start-up, the trans-
mission must be
fi
lled with trans-
mission
fl
uid. For
fi
lling procedure,
fl
uid type, quantity and level refer to
chapter 6.1.4
fl
uid change.
CAUTION
Using the transmission with an in-
suf
fi
cient oil level will damage the
gears. An excessive oil level may
cause leakage at the shaft seals
and the transmission breather, and
raise the operating temperature
considerably.
5.1.1 OPERATION
PROCEDURE
CAUTION
Before operating the transmis-
sion, check
fl
uid level (see chapter
6.1.1).
CAUTION
During normal operation, the trans-
mission should only be shifted with
the engine at idle speed. Shifting at
higher engine speed may lead to
overstress of the friction disks of
the coupling and should be avoided
in normal operation.
NOTE:
The transmission may be
shifted from forward to reverse in case
of emergency, even at high engine
speed.
SHIFTING POSITIONS (
fi
gure 7):
A = Propeller rotation opposite of
engine
rotation
N = Neutral position
B = Propeller rotation same as engine
rotation
WARNING
Start engine with transmission in
neutral only.
Normal operating temperature of the
transmission oil should be in the range
of 50°C (122°F) to 80°C (176°F).
Max. permissible ATF temperature of
100°C (212°F) may only be reached
for a short time.
CAUTION
If the
fl
uid temperature is too high,
stop engine immediately and check
transmission fluid level and oil
cooler for proper water
fl
ow.
Do not start the engine again until
the malfunction is eliminated.
5.1.2 SAILING,
TUGGED
OR
ANCHORED
The propeller may turn owing to the
effect of the current when the engine
is off and the craft is sailing, or when it
is tugged or anchored. This represents
no danger for the transmission. In a
boat with two engines, the propeller
of the unused transmission may idle
freely. When the engine is off, the posi-
tion of the shifting lever is irrelevant.
CAUTION
Idling position of the propeller: gear
shift lever must be in «N» (Fig.7)
position. Use the shift position
opposite to the direction of travel
for locking the propeller shaft, oth-
erwise the transmission will be
damaged.
WARNING
Do not work on the transmission
when being towed, or anchoring in
a river because the propeller may
rotate.
WARNING
Do not work on the transmission in
a twin engine boat, when one unit
is under power. The propeller shaft
of the inoperative transmission will
rotate.
WARNING
When the engine runs idle, but the
propeller shaft should not be driven
(such as when charging the battery
with the generator), the shifting
lever (
fi
gure 7) must be held in the
neutral position (N) to prevent the
boat from moving.
Avoid to run the hydraulic gearbox
in neutral at high engine speed for
a long time.
5.1.3 CONTROL
SYSTEM
CAUTION
Make certain that control rod or
cable is easily movable.
