McCulloch products are identified by a model number (in this
instance 400132) followed by a suffix number (91). Suffix
numbers denote variations in parts or assemblies used in the
manufacture of this product.
Illustrated Parts Lists (IPLs) contain a PART NUMBER,
DESCRIPTION, UNITS per assembly and STOCKING CODE for
each part.
Stocking Codes are:
A - Dealer stocked. Fast to medium moving part.
B - Distributor stocked. Medium to slow moving part.
C - Factory stocked. Slow moving part.
NOTE: The following explains symbols and footnotes in
this IPL:
(-)
A dash preceding a PART NUMBER indicates
that it is a new part number, different from the
one listed in the previous IPL for this unit.
(.)
One or more dots (. Spring, Starter) preceding
a part DESCRIPTION indicates the part is
included in the kit or assembly described
directly above the dot(s).
(-- --)
If four dashes appear in place of a PART
NUMBER, the part is not available individually
but is included in the next higher assembly or
subassembly.
Circled numbers preceding a DESCRIPTION
footnote the part or assembly to additional
information on the page.
(*)
As asterisk denotes that choices follow or
precede.
(†)
Serial Number Prefix (in this instance 22-)
denotes CARB approved unit -- all parts are
interchangeable with Serial Number Prefix
(12-).
The policy of McCulloch is one of continual improvement in
design, manufacturing and engineering advancement
wherever possible to assure still finer power tools. Hence,
specifications, equipment colors, design and manufacturer’s
suggested list prices are subject to change without notice.
McCulloch reserves the right to make such changes without
prior notification or obligation to backfit or supply backfit
components for units previously shipped from the factory.
