Foreword

5. Drawing method of illustrations in this service manual

The third angle projection method of mechanical drawing is used for the illustrations in this service manual.

The third angle projection method is generally composed of the front view (the figure viewed from the front:

A), top view (the figure viewed from the top: B), and right-side view (the figure viewed from the right: C) as

shown below. Draw the top view immediately above the front view, and draw the right-side view on the right

side of the front view. Tridimensional shape can generally be drawn with the figures viewed from 3 directions.

For those which cannot be drawn with the figures viewed from 3 directions, the additional figures, such as

left-side view (the figure viewed from the left: D), back view (the figure viewed from the back: E), or bottom

view (the figure viewed from the bottom: F) may be used.

For other cases, when individual detailed drawing is required, an arrow view, sectional view, or detail drawing

may be used separately.

A: Front view

B: Top view

C: Right-side view

D: Left-side view

E: Back view

F: Bottom view
