7.4 PREVENTIVE MAINTENANCE
The following items should be checked as part of routine maintenance on a monthly
basis:
•
Check all cables; replace if damaged
•
Check all connectors at the rear of each unit; clean, if necessary, and replace if
damaged
•
Check all ground connections for each unit; clean, if necessary, and replace if
corroded
•
Check supply voltage to ensure it is within the equipment power rating
7.4.1 Lubrication (SL 35 Only)
Grease the lower and raise main shaft bearing twice a year, using Shell “SRS 2000”
water resistance grease. A grease fitting is installed on the tank flange to facilitate
the greasing. Note that a “
VENT” plug located on the opposite side must be
removed prior to applying the grease. If the “VENT” plug is not removed, you will
damage the O-Ring and shaft seals.
See Part 8 “Attachments and Drawings” for the grease fitting location.
7.4.2 Manually Raising Sonar Dome (SL 35 Only)
The manual pump should be tested twice a year, to ensure proper operation as
follows:
•
First, lower the sonar dome via the operator panel
•
Check that the sonar dome is fully lowered
•
Next, turn ON/OFF the power switch located on the transceiver unit to the OFF
position
•
Manually activate the hand pump until the sonar dome is totally retracted into the
ship hull.
•
If the sonar dome cannot be raised smoothly, do not use excessive force; the
shaft may be bent and will cause damage to other components.
•
Next, turn the power switch to ON, the sonar dome will automatically be lowered.
