McCulloch MS1635AV User Manual

McCulloch products are identified by a model number (in this instance

600035) followed by a suffix number (08). Suffix numbers denote variations in parts or assemblies used in the manufacture of this product.

Illustrated Parts Lists (ILPs) 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.

(*)

An asterisk denotes that choices follow or precede.

(†)

Serial Number Prefix 21- denotes CARB approved unit

-- all parts are interchangeable with Serial Number Prefix 11-.

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.
