FOREWORD
This manual is written for an experienced technician.
Essential tools required in performing certain service
work are identified in this manual and are
recommended for use.
Live with safety: Read the safety messages in the
introduction of this manual and the cautions
presented throughout the text of the manual.
N This is the safety-alert symbol. When you see
this symbol on the machine or in this manual,
be alert to the potential for personal injury.
Technical manuals are divided in two parts: repair
and diagnostics. Repair sections tell how to repair the
components. Diagnostic sections help you identify the
majority of routine failures quickly.
Information is organized in groups for the various
components requiring service instruction. At the
beginning of each group are summary listings of all
applicable essential tools, service equipment and
tools, other materials needed to do the job, service
parts kits, specifications, wear tolerances, and torque
values.
Binders, binder labels, and tab sets can be ordered
by John Deere dealers direct from the John Deere
Distribution Service Center.
This manual is part of a total product support
program.

Fundamentals of Service (FOS) Manuals cover basic
theory of operation, fundamentals of troubleshooting,
general maintenance, and basic type of failures and
their causes. FOS Manuals are for training new
personnel and for reference by experienced
technicians.
Technical Manuals are concise guides for specific
machines. Technical manuals are on-the-job guides
containing only the vital information needed for
diagnosis, analysis, testing, and repair.
Component Technical Manuals are concise service
guides for specific components. Component technical
manuals are written as stand-alone manuals covering
multiple machine applications.

OPERATE CLIPPER AND TRIMMERS SAFELY
Keep people and pets out of the area where you are
using the machine.
Unauthorized modifications to the machine may impair
the function and/or safety and affect machine life.
Do not run engine in an enclosed area. Exhaust
fumes contain carbon monoxide, an odorless and
deadly poison.
Keep machine hand grips clean and dry.
When operating machine, hold firmly with both hands.
Keep proper footing and balance.
Move machine away from your body. Do not draw
blades or cutting head toward you. Do not reach to
make a cut.
When operating trimmer with optional blade installed,
always use shoulder harness and grip handlebars
securely.
Use metal shield when using blades on
trimmer/cutter.
Take precautions to avoid “kickback”.
If cutting blade or blades are cracked, replace
immediately.
Do not attempt to fill fuel tank, make adjustment or
clean while engine is running.

DESCRIPTION
The engine used in these machines is of a
single-cylinder, 2-cycle, air-cooled, piston-ported design.
Crankshafts are made of chromium molybdenum steel
with case-hardened bearing surfaces. The crankshaft is
supported by two large ball bearings.
Select-fit needle bearings are used on both ends of the
connecting rod.
The cylinders have porous, chrome-plated or alfed plated
bores.
PRINCIPLE OF OPERATION
The 2-cycle engine is used on these machines because
of its excellent horsepower-to-weight ratio, ability to
operate in any position, and good cold weather starting.
The 2-cycle engine provides a power stroke with every
revolution of the crankshaft.
As the piston moves upward, it lowers the pressure in
the crankcase (A) and exposes the intake port (B),
drawing a fuel-air mixture into the crankcase through the
carburetor.
TY8007
-UN-04MAY89
As the piston moves downward, it pressurizes the
crankcase (A) and causes this fuel-air mixture to move
up the transfer ports (B), into the combustion chamber
(C).
