In case of emergency
Emergency shifting
If a fault occurs which prevents the revers gear from
being operated (shifted) with the control lever, it is
possible to shift manually, using the description
below.
Note. The descriptions refer to electrically shifted re-
vers gear.
WARNING! In emergency shifting, the unit is
locked in forwards operation. Please note that
the revers gear can not then be disengaged
with the control lever. Forward motion can only
be cut off by stopping the engine with the igni-
tion key or stop button.
