3.2 Operating temperature
The max. permissible temperature
of
the transmission oil
is
130
0e.
3.3 Operation
of
gearbox
Shifting
is
initiated
by
a cable
or
rod linkage
via
the actuating lever and
an
actuat-
ing
cam. The completion
of
the
gear
changing operation
is
automatic and cannot
be
influenced
by
external control. The actuating lever
is
mounted on
an
actuating
shaft and fixed
by
means
of
a retaining screw.
Gear changing should
be
smooth,
not
too
slow, and continuous
(without
inter-
ruption). The multiple-disc clutch permits
gear
changing at high engine rpm, in-
cluding sudden reversing at
top
speeds
in the event
of
danger.
3.4 Operation
without
load
Rotation
of
the propeller
without
load,
e.g.
while the boat
is
sailing, being towed,
or
anchored in a river,
as
well
as
idling
of
the engine
with
the propeller stopped,
will
have
no detrimental effects on the gearbox.
Locking
of
the propeller shaft
by
an
additional brake
is
not
required. since lock-
ing
is
possible
by
engaging the
reverse
gear.
3.5 Lay-up periods
If
the transmission
is
not
used
for
periods
of
more than 1 year
it
should
be
com-
pletely
filled
with
oil
of
the
same
grade
to
prevent corrosion. Protect the
input
shaft and the
output
flange
by
means
of
an
anticorrosive coating
if
required.
3.6 Preparation
for
re-use
Drain
the
transmission
of
all
oil
and
refill
to
the
proper
level
with
the
prescribed
oil.
