OPERATING THE MAKO UNDERWATER
Flashing Red
FIG. 14 - STOP Operation
What To Do If Your Vehicle
Becomes Inoperative
For easy viewing, the battery life indicator is located in the center of the
top surface of the main housing, and should be continuously monitored
whenever the vehicle is in use; no less often than you check your depth
and pressure gauges.
Each dive should be pre-planned according to no-decompression limits,
anticipated air consumption, and anticipated battery running time.
Whenever the yellow battery indicator light appears, however, you should
immediately begin your return to the boat or exit point, and discontinue
operation of the vehicle when the red low battery indicator appears.
WARNING: Immediately STOP operating the vehicle
whenever the flashing red battery indicator light appears
(Fig. 14). If the vehicle is in operation underwater when
this light appears, abort the dive and make a safe con-
trolled ascent to the surface to re-charge the batteries as
soon as possible. Swim the vehicle to the surface, and DO
NOT continue to operate.
If your vehicle becomes inoperative underwater for any reason, you must
safely return to the surface as soon as possible to examine the cause. DO
NOT attempt to operate the vehicle any further.
To exert the least amount of effort while swimming with an inoperative
vehicle, it is recommended to hold it in its normal use position, being
extremely careful to avoid depressing the activation triggers in either of
the side handles. While making your final ascent to surface, hold the
vehicle by the carrying handle in the top of the fore shell - especially
when it is necessary to hold onto a line or decompression bar with one
hand.
If the propellor has been fouled by an obstruction, the Mako’s safety
clutch will automatically disengage, and a loud clicking sound will be
heard while the motor remains activated. When the obstruction is re-
moved, the clutch may be re-engaged by depressing the activation switch
briefly several times. When the clicking sound is no longer heard, the
clutch has been re-engaged.
CAUTION: If a loud clicking sound is heard, indicating
that the safety clutch has disengaged, immediately re-
lease the activation triggers in both of the side handles to
stop the motor, and safely return to the surface to remove
the obstruction. DO NOT attempt to remove the obstruc-
tion underwater.
WARNING: If air can be seen leaking from the Mako’s
housing, indicating that water has entered, the vehicle
should be considered inoperative and returned to the
surface immediately using the procedures described
above. As soon as possible, remove the fore shell to open
the housing and DO NOT re-seal until the vehicle has
received factory authorized service by an Authorized
Oceanic Dealer.
