2. Perform visual, electrical and mechanical checks on
all components on a regular base.
3. Visually check for undue heating evidenced by
discoloration of wires or other components, damaged
or worn parts or leakage evidenced by water or
corrosion in the interior.
4. Electrical check to make sure that all connections are
clean and tight, and that contacts in the components
make or break as required.
5. Mechanically check that all parts are properly
