CHAPTER 6 MAINTENANCE AND WARRANTY
6.1 MAINTENANCE
The only parts of the SW AP03 requiring maintenance are the mechanical components of
the steering gear. Chain drives and the rudder transducer linkage (but not the transducer

CAUTION: Lubricate the clutch very sparingly, using a very light oil.
For hydraulic systems, follow the maintenance instructions supplied with the system.

accidentally immersed in water, it should be drained immediately and returned promptly to
your distributor agent for cleaning and rectification.
