Seiwa SW AP01 - Manual (Page 51)

CHAPTER 6 MAINTENANCE AND WARRANTY
6.1 MAINTENANCE
The only parts of the SW AP01 system requiring maintenance are the mechanical
components of the steering gear. Please refer to the hydraulic steering system manual
for maintenance instructions.
6.2 INSTALLATION OF NEW SOFTWARE
It is recommended that software upgrades be installed by a Seiwa agent, but if this is not
possible, the following procedure should be followed carefully by the owner. The memory
package containing the software for the main circuit board in the Junction Box has a label
beginning CM842V2.. Open the Junction Box and, referring to Fig 3.1 in the manual, locate
the Program Store. Slip a slim bladed screwdriver through the access hole at the rear of the
base, inserting it between the package and its socket. With a gentle twisting movement of
the screwdriver, lever the package up so that it remains parallel to the surface of the board
until free of the socket.
Check the new package to ensure that all pins are straight and at right angles to the
package. If they tend to splay outwards, bend them inwards by rocking the package on a
hard smooth surface. Insert the package in the socket, making certain that the small notch
at the end of the package lines up with the small notch on the socket.
