Assembly Procedure
i01167078
Note: Cleanliness is an important factor. Before assembly, all parts should be thoroughly cleaned in cleaning fluid. Allow the parts to air dry. Wiping cloths or rags should not be used to dry parts. Lint may be deposited on the parts which may cause later trouble. Inspect all parts. If any parts are worn or damaged, use new parts for replacement.
Note: Do not strike the diodes. The shock of such an impact can damage the diodes. Use proper tools in order to press the diodes in the mountings.
