INTRODUCTION
Read this Operation Section and the sepa-
rate Engine Owner’s Manual before you
start the engine. Then, take the time to
familiarize yourself with the basic opera-
tion of the tiller before using it in the
garden. Find an open, level area and prac-
tice using the tiller controls without the
tines engaging the soil (put tines in
“travel” setting). Only after you’ve
become completely familiar with the tiller
should you begin using it in the garden.

Before operating your machine, care-
fully read and understand all safety
(Section 1), controls (Section 3) and
operating instructions (Section 4) in
this Manual, in the separate Engine
Owner’s Manual, and on the decals on
the machine.
Failure to follow these instructions can
result in serious personal injury.
WARNING
GASOLINE IS HIGHLY FLAMMABLE AND
ITS VAPORS ARE EXPLOSIVE.
Follow gasoline safety rules in this
Manual (see Section 1) and in the sepa-
rate Engine Owner’s Manual.
Failure to follow gasoline safety instruc-

injury and property damage.
DANGER
To help prevent serious personal injury
or damage to equipment:
• Before starting engine, put both
wheels in the WHEEL DRIVE position.
Never have wheels in FREEWHEEL
position when engine is running.
When the wheels are in FREEWHEEL,
they do not hold back the tiller and the
tines could propel the tiller rapidly
forward or backward.
• Before starting engine, put Forward
Clutch Bail (all models) and Reverse
Clutch Control (Models 12209/12210
only) in neutral (disengaged) positions
by releasing levers.
• Never run engine indoors or in
enclosed, poorly ventilated areas.
Engine exhaust contains carbon
monoxide, an odorless and deadly gas.
• Avoid engine muffler and nearby
areas. Temperatures in these areas
may exceed 150
