6 Maintenance

6.1 General

The AP28 units are “repair by replacement” units, and the

operator is therefore required to perform only a very

limited amount of preventive maintenance.

6.2 Control unit

The AP28 Control Unit will under normal use require little

maintenance.

If the unit requires any form of cleaning, use fresh water

and a mild soap solution (not a detergent). It is

important to avoid using chemical cleaners and

hydrocarbons such as diesel, petrol etc.

Make sure that all open SimNet connectors are

fitted with a blocking plug (part no 24006355).

It is advisable at the start of each season to check all

connections to the control unit head and cover with

Vaseline or WD40.

Always put on the weather cover when the unit is not in

use.

6.3 Autopilot Computer

No special maintenance is required. It is advisable,

however, at the start of each season to make a visual

inspection of the internal and check all connections.

6.4 Rudder Feedback

Make a visual inspection at 2-3 month intervals and at

the start of each season. Apply some grease at the ball

joints when required (RF300, RF25)
