EXPLODED VIEW
• Items with no part number and no description are not stocked
because they are seldom required for routine service.
• The component parts of an assembly are indicated by the
reference numbers in the remarks column.
• Items marked with an asterisk " * " are not stocked since they are
seldom required for routine service. Some delay should be
anticipated when ordering these items.
The components identified by shading and "!" a re critical
for safety. Replace only with specified part number.
Les composants identifies per un trame et une marque ! sont
