SECTION 2 - SAFETY
WARNING: This cutting machine is capable of
amputating hands and feet and throwing
objects. Failure to observe the safety
instructions in the manuals and on decals could
result in serious injury or death.
Slopes are a major factor related to loss-ofcontrol and tip-over accidents. Operation on all
slopes requires extra caution.
Tragic accidents can occur if the operator is not
alert to the presence of children. Never assume
that children will remain where you last saw
tf^m.
Gasoline is extremely flammable and the vapors
are explosive, handle with care.
Disengage attachment, stop unit and engine,
remove key, engage parking brake, and allow
moving parts to stop before leaving operator’s
position.
2.1 SAFETY ALERTS
These are safety alert symbols. They
mean:
A
A
•ATTENTION!
OL1253

clothing inside or near any moving part while unit is
running.
NEVER direct discharge towards persons or property.
Thrown objects may ricochet back towards operator.
ALWAYS stand clear of the discharge area.
ALWAYS disengage attachment, stop unit and engine,
remove key, engage parking brake, and allow moving
parts to stop before leaving operator’s position.
Use extreme caution on gravel surfaces.
Disengage PTO when attachment is not in use and
when crossing gravel surfaces.
DO NOT operate unit if safety interlock system is
damaged or disabled. Check safety interlock before
each use.
ALWAYS remove key to prevent unauthorized use.

necessary. ALWAYS look down and behind before and
while backing; especially for children.
Follow the manufacturer’s recommendations for wheel
weights or countenveights to improve stability when
using attachments.
NEVER carry passengers-especialiy children-even
with blades off.
Use extra care when approaching blind corners or
objects that may obscure vision of hidden obstacles
and children.
If you cannot back up a slope or you feel uneasy on it,
do not mow it.
Mow up and down slopes, not across them.
Use slow speed on any slope. Tires may lose traction
on slopes even though the brakes are functioning
properly.
Keep all movements on the slope s/ow and gradual.
DO NOT make sudden changes in speed or direction.

operation.
NEVER fill or drain fuel tank indoors.
NEVER overfill fuel tank.
Replace fuel cap securely and clean up spilled fuel.
NEVER fill containers inside a vehicle or on a truck or
trailer bed with a plastic liner. Always place containers
on the ground away from your vehicle before filling.
When practical, remove gas-powered equipment from
the truck or trailer and refuel it on the ground. If this is
not possible, then refuel such equipment on a trailer
with a portable container, rather than from a gasoline
dispenser nozzle.
Keep the nozzle in contact with the rim of the fuel tank
or container opening at all times until fueling is
complete. Do not use a nozzle lock-open device.
If fuel is spilled on clothing, change clothing
immediately.
Avoid Electric Shock. Objects contacting both battery
terminals at the same time may result in injury and unit
damage. DO NOT reverse battery connections.
Explosive Gases from battery can cause death or
serious injury. Poisonous battery fluid contains sulfuric
acid and its contact with skin, eyes or clothing can
cause severe chemical burns.
NO flames, NO sparks, NO smoking near battery.
ALWAYS wear safety glasses and protective gear near
battery.
DO NOT TIP battery beyond a 45° angle in any
direction.
ALWAYS keep batteries out of reach of children.
Battery posts, terminals and related accessories
contain lead and lead compounds, chemicals known to
the State of California to cause cancer and
reproductive harm. Wash hands after handling.
Reverse connections may result in sparks which can
cause serious injury. Always connect positive (+) lead
of charger to positive (+) terminal, and negative (-) lead
to negative (-) terminal.
ALWAYS disconnect negative (-) cable FIRST and
positive (+) cable SECOND. ALWAYS connect positive
(+) cable FIRST, and negative (-) cable SECOND.
A frozen battery can explode and result in death or
serious injury. DO NOT charge or jump start a battery
containing frozen fluid. Thaw the battery before putting
on a charger or jump starting.

provide good ventilation.
ALWAYS maintain unit in safe operating condition.
Damaged or worn out muffier can cause fire or
explosion.
Stop and inspect equipment if you strike an object or if j
there is an unusual vibration. Repair, if necessary,
before restarting. Never make adjustments or repairs
with the engine running.
Mower blades are sharp and can cut you. Wrap the
blade(s) or wear gloves, and use extra caution when
servicing them. NEVER weld or straighten mower
blades.
Rotation of one blade may cause rotation of the other
blades.
Check brake operation frequently. Adjust and service
as required.
Keep all hardware properly tightened.
Stored energy in springs can cause injury.
Maintain or replace safety and instruction labels, as
necessary.
Never store the machine or fuel container inside a
building where there is an open flame, such as a watei|
heater.
Allow engine to cool completely before storing in
closed area or covering unit.
For extended storage, clean unit thoroughly. See
Engine Manual for proper storage.
Use only attachments or accessories designed for you|
unit.
Check attachment components frequently. If worn or
damaged, replace with manufacturer’s recommended]
parts.
2.5 SERVICE POSITION
CAUTION: Remove enough fuel so that no
spillage will occur. Remove battery to prevent
spillage of electrolyte.
WARNING: Always block wheels and know
that jack stands or blocks used are stable,
strong or secure and will hold the weight of
the unit during maintenance.
To ensure that unit is positioned in the proper service]
position:
1. Place jack stands under rear transaxle only.
2. If jacks are not available, place support blocks
under the transaxle at the rear of unit.
2-6
2.6 CLEANING AND STORAGE
IMPORTANT: Never spray unit with water or store unit
outdoors to help prevent sealed bearing rust or
corrosion. Water can seep into sealed bearings and
reduce component life. Bearings are sealed against dirt
and debris only.
A unit that is excessively dirty should be cleaned before
work starts. Cleaning will occasionally uncover trouble
sources. Dirt and abrasive dust reduce the efficient
work life of parts and can lead to costly replacement.
When taking unit out of extended storage:
1. Check for any damage or loose parts. Repair,
replace or tighten hardware before operation.
2. If a preservative fluid was used in fuel tank, drain
aR(| discard. Fill fuel tank with fresh new fuel.
2.7 MOVING THE UNIT MANUALLY
WARNING: DO NOT disengage or bypass
transmission and coast downhill.
