4-4 Maintenance &

Troubleshooting

To replace the boards inside the tree, first remove the front cover by removing the eight

screws securing it to the tree. Then, remove the single screw at the top of the board and

remove it by pulling it straight out of its socket. Install the new board by reversing the

procedure. Be sure to reinstall the screw holding the PC board in place before plugging the

tree back in.

A 20-amp fuse is located at the rear of the tree. If it blows repeatedly, do not change the

rating. There is a problem with the PC boards or internal wiring.
