MAQ Standard Maintenance Checks.
Transducers
1. Zinc Anodes mounted on transducer pipes must be inspected when possible and
replaced yearly. (excessive erosion of Zinc Anodes indicates improper grounding)
2. Transducer must be inspected yearly. Signs of aquatic life accumulation on the
shield or inside the shield must be corrected for best sonar performance (see
transducer maintenance procedure). Remove shield if required and clean
transducer active face and shield with muriatic acid.
Hoists
1. Hoists Actuators should be inspected monthly for sufficient grease on Actuator
shaft.
2. Packing glands should be greased and checked for leaks regularly. Replace packing
material as required. (Caution do not over tighten hoist compression gland as it will
overload the actuator)
3. Hoist pipe and Sea-chest must not vibrate. If this is occurring inspect Sea-Chest
guides for excessive wear or improper adjustment and readjust or replace UHMW
slider blocks or improve support to Sea-Chest.
4. Hoist pipes must be connected to ships electrical ground at all times. (ensure pipe
is properly grounded)
5. Hoist pipe openings must not be exposed to water or spray. If water is detected
inside hoist pipes this may indicates problems with the transducer to pipe interface
and should be corrected immediately.
Electronics
1. All cases must be connected to ships electrical ground at all times.
2. When inspecting electronics, ensure AC power is disconnected before changing
boards, connecting cables, or removing, or replacing parts.
3. Fans must be checked for free running operation regularly.
4. All Indicator Lights must be Lit or flashing appropriately. (See troubleshooting
section)
5. Cases must be positioned in areas free of continuous water spray and in an area
with maximum ambient temperature of 40°C.
6. Case seals should be inspected for signs of water leakage. Cases should be
inspected for signs of corrosion.
7. Appropriate fuses must be installed if changing main AC supply voltages or
upgrading to RDT. (Standard fuse will be installed before shipping from factory)
8. Ensure all cable connections are securely fastened.
