WARNING
This machine meets voluntary safety standard B71.1 –
1998, which is sponsored by the Outdoor Power
Equipment Institute, Inc., and is published by the American
National Standards Institute.
Safety Alert Symbol
This is a safety alert symbol. It is used in this
manual and on the unit to alert you to potential
hazards. When you see this symbol, read and
obey the message that follows it. Failure to obey
safety messages could result in personal injury or property
damage.
I. GENERAL OPERATION
1. Read, understand and follow all
instructions on the machine and in
the manuals provided with the unit.
Be thoroughly familiar with the
controls and the proper use of the
mower before starting.
2. Do not put hands or feet near or
under rotating parts. Keep clear of
the mower blade and discharge
opening at all times.
3. Only allow responsible individuals,
who are familiar with the instructions, to operate the mower.
4. Clear the area of objects such as
rocks, toys, wire, bones, sticks, etc.,
which could be picked up and thrown
by the blade.
5. Be sure the area is clear of other
people before mowing. Stop mower if
anyone enters the area. Keep
bystanders at least 25 feet away from
the area of operation.
6. Do not operate the mower when
barefoot or wearing open sandals.
Always wear substantial foot wear.
7. Do not pull mower backwards unless
absolutely necessary. Look down and
behind before and while moving
backwards.
8. Do not operate mower without all
guards in place and either the entire
Grass Catcher, the Mulching Plug or
the Side-Discharge Chute installed.
ROTATING BLADES— Do not open
discharge guard while engine is
running.
9. Refer to provided instructions for
proper operation and accessory
installation. Use only accessories
approved by Garden Way Inc.
10. Shut off engine when crossing gravel
drives, walks, or roads.
11. Stop engine and disconnect spark
plug wire from spark plug whenever
you leave unit, before cleaning mower
or unclogging chute.
12. Shut the engine off and wait until the
blade comes to a complete stop
before installing or removing the
Mulching Plug, Side-Discharge Chute
or the Grass Catcher. Make certain
that an attachment is installed before
operating the mower. Empty the
Grass Catcher after each use–
decomposing debris could generate
enough heat to catch fire.
13. Mow only in daylight or in good artificial light.
14. Do not operate mower while under
the influence of alcohol or drugs.
15. Never operate mower in wet grass.
Always be sure of your footing; keep
a firm hold on the handle and walk;
never run.
16. Be sure Wheel Drive Bail is disengaged before starting engine.
17. If the unit should start to vibrate
abnormally, stop the engine and disconnect the spark plug wire. Then
check immediately for the cause.
Vibration is generally a warning of
trouble.
18. We recommend that you wear safety
goggles or safety glasses when
operating the mower.
19. Watch for traffic when operating
near, or when crossing roadways.
20. Never attempt to carry children or
other passengers on the mower.
They could fall off and be seriously
injured, or they could interfere with
the safe operation of the mower.
21. Check the operation of the Operator
Presence Control Bail (top bail,
mounted on handlebar) before each
use. The Operator Presence Control
Bail is a safety device that is designed
to stop the mower blade within three
seconds after releasing the bail. The
bail must operate freely when pulled
back against the handlebar and
return automatically to the disengaged position when released. If the
engine runs longer than three
seconds after releasing the bail, the
system is not working properly.
Immediately contact an authorized
service dealer or the Factory
Technical Service Department for
instructions. Do not use the mower
until the mechanism is repaired.
22. Never run the engine in an enclosed
area. Engine exhaust contains carbon
monoxide, a deadly gas that is
odorless, colorless and tasteless.
Always run the engine outdoors and
make sure there is adequate
ventilation.

Section 1: Safety
II. OPERATING ON A SLOPE
Slopes are a major factor related to slip
and fall accidents which can result in
severe injury. All slopes require extra
caution. If you feel uneasy on a slope,
do not mow it.
DO:
Mow across the face of slopes; never
up and down. Exercise extreme
caution when changing direction on
slopes. Avoid slopes greater than 15
o
.
Remove objects such as rocks, tree
limbs, etc.
Watch for holes, ruts, or bumps. Tall
grass can hide obstacles.
DO NOT:
Do not mow near drop-offs, ditches,
or embankments. The operator could
loose footing or balance.
Do not mow excessively steep slopes.
Do not mow on wet grass. Reduced
footing could cause slipping.
III. CHILDREN
Tragic accidents can occur if the
operator is not alert to the presence of
children. Children are often attracted to
the mower and to the mowing activity.
Never assume that children will remain
where you last saw them.
1. Keep children out of the mowing area
and under the watchful care of a
responsible adult.
2. Be alert and turn mower off if
children enter the area.
3. Before and while moving backwards,
look behind and down for small
children.
4. Never allow children to operate the
mower.
5. Use extra care when approaching
blind corners, shrubs, trees, or other
objects that may obscure vision.
IV. SERVICE
1. Use extra care in handling gasoline
and other fuels. They are flammable
and their vapors are explosive.
a) Use only an approved container.
b) Never remove gas cap or add fuel
when the engine is running.
Allow engine to cool before
refueling. Do not smoke.
c) Never refuel the machine
indoors.
d) Never store the machine or fuel
container inside where there is an
open flame, such as a water
heater, etc.
e) Move mower away from any
gasoline fumes before starting
the engine.
2. Never run an engine inside a closed
area.
3. Never make adjustments or repairs
with the engine running. Disconnect
the spark plug wire and move the
wire away from the plug to prevent
accidental starting.
4. Keep all nuts and screws, especially
the blade attachment bolts, tight and
keep equipment in good condition.
5. Never tamper with safety devices.
Check their operation regularly.
6. Keep mower free of grass, leaves or
other debris build-up. Clean up oil or
fuel spillage. Allow mower to cool
before storing.
7. After striking an object, stop the
engine and disconnect the spark plug
wire. Inspect the mower and repair, if
necessary, before restarting.
8. Never attempt to make mower cutting
height adjustments while the engine
is running.
9. Grass catcher components are
subject to wear, damage and deterioration, which could expose moving
parts or allow objects to be thrown.
Frequently check components and
replace with factory recommended
parts, when necessary.
10. The mower blade is sharp and can
cut. Wrap the blade or wear gloves,
and use extra caution when servicing.
11. Do not change the engine governor
setting or overspeed the engine.
12. Do not touch engine parts which may
be hot from operation. Allow parts to
cool completely before inspecting,
cleaning or repairing the mower.
13. Maintain or replace safety and
instructional decals. Refer to the
Parts List for replacement decal
information.
