NOTICE
Allow the engine(s) to warm up before en-
gaging the shift control. Monitor all instruments
while engine is idling during warm up.
A. Neutral Safety Switch
Every control system has a neutral safety switch incor-
porated into it. This device prohibits the engine from
being started while the shift lever is in any position
other than the neutral position. If the engine will not
start, slight movement of the shift lever may be
necessary to locate the neutral position and disen-
gage the safety cutout switch. Control or cable
adjustments are required to correct this condition
should it persist. See your Scarab dealer for neces-
sary control and cable adjustments.
B. Emergency Engine Shut Off Switch
This safety device automatically stops the engine if
the lanyard is attached to the operator and the
operator falls from his helm station. Refer to the
manufacturer's literature for additional information
about using this switch.
The emergency engine shut off switch (Figure B3)
incorporates a shut off (interrupter) switch, switch clip,
lanyard, and lanyard clip. The lanyard clip must be
securely attached to the operator's PFD, clothing,
arm, or leg. Be sure to attach the lanyard to a place
where it is free of obstructions and to something that
will move with the operator if he or she leaves the
helm station. If the engine shuts down because this
switch was activated, the clip must be reinstalled on
the interrupter switch before the engine can be
started.
