Read this manual carefully to learn how to operate
and maintain your product correctly. Reading this
manual will help you and others avoid personal injury
and damage to the product. Although Lawn-Boy
designs, produces and markets safe, state-of-the-art
products, you are responsible for using the product
properly and safely. You are also responsible for
training persons who you allow to use the product
about safe operation.
The Lawn-Boy warning system in this manual
identifies potential hazards and has special safety
messages that help you and others avoid personal
injury, even death. DANGER, WARNING and
CAUTION are signal words used to identify the level
of hazard. However, regardless of the hazard, be
extremely careful.

EN–2
DANGER signals an extreme hazard that will cause
serious injury or death if the recommended
precautions are not followed.
WARNING signals a hazard that may cause serious
injury or death if the recommended precautions are
not followed.
CAUTION signals a hazard that may cause minor or
moderate injury if the recommended precautions are
not followed.
Two other words are also used to highlight
information. “Important” calls attention to special
mechanical information and “Note” emphasizes
general information worthy of special attention.
Safety
This machine meets or exceeds CPSC blade safety
requirements for walk–behind rotary mowers and
the B71.1 specifications of the American National
Standards Institute, in effect at time of
production. However, improper use or
maintenance by the operator or owner can result
in injury. To reduce the potential for injury,
comply with these safety instructions and always
pay attention to the safety alert symbol which
means CAUTION, WARNING or
DANGER—“personal safety instruction.” Failure
to comply with the instruction may result in
personal injury.
Safe Operating Practices
This product is capable of amputating hands and feet
and throwing objects. Always follow all safety
instructions to avoid serious injury or death.
POTENTIAL HAZARD
•Engine exhaust contains carbon monoxide,
which is an odorless, deadly poison.
WHAT CAN HAPPEN
•Carbon monoxide can kill you and is also
known to the State of California to cause
birth defects.
HOW TO AVOID THE HAZARD
•Do not run engine indoors or in an enclosed
area.
This mower is designed for cutting and mulching
grass or, when equipped with a grass bag, for
catching cut grass. Any use for purposes other than
these could prove dangerous to user or bystanders.
Note: This engine is NOT equipped with a
spark arrester muffler. Use or operation
of this mower in the State of California
on any forest-covered, brush-covered
or unimproved grass-covered land,
without an approved spark arrester
muffler, is a violation of the law. Other
states may have similar laws.
General Operation
1. Read this manual carefully before operating the
mower. Become familiar with the controls and
proper use of the mower. Never allow children to
operate the mower or adults to operate it without
proper instructions.
2. Keep everyone, especially children and pets,
away from area of operation. Thoroughly inspect
area where mower will be used and remove
sticks, stones, wire, and debris.
3. Wear long pants and substantial shoes. Do not
operate mower while wearing open-toed shoes,
loose clothing, jewelry or when barefoot.
4. Check fuel level before starting engine. Do not
fill fuel tank indoors, when the engine is
running, or until engine cools for several
minutes after running. Wipe up spilled gasoline
before starting engine.

EN–3
5. Keep all guards, shields (including rear trailing
shield), grass catchers and safety devices in
place. Repair or replace damaged parts,
including decals.
6. Engine, blade and self–propelled drive are
designed to stop when control bails are released.
Ensure control and brake function properly
before each use of mower.
While Operating
1. Do not run engine indoors.
2. Always maintain secure footing. Keep a firm
grip on the handle and walk; never run. Never
operate mower in wet grass. Mow only in
daylight or in good artificial light.
3. Mow across the face of slopes; never up and
down. Use extreme caution when changing
direction on slopes. Do not mow excessively
steep slopes.
4. Always wear safety glasses or eye shields during
operation to protect eyes from foreign objects
that may be thrown from the machine. Keep
face, hands, and feet away from the mower
housing and cutter blade when the engine is
running. Stay behind the handle until the engine
stops.
5. Since the blade rotates for a few seconds after
the blade control bail is released, stay behind the
handle until all movement stops.
6. After striking a foreign object or if mower
vibrates abnormally, stop engine and remove
wire from spark plug. Check mower for damage
and make all repairs before using mower again.
7. Stop the engine before adjusting the
height–of–cut.
8. Stop the blade/engine when crossing a gravel
driveway, road, or sidewalk.
9. Stop engine before leaving the operator’s
position – behind the handle. Disconnect wire
from spark plug if mower will be unattended.
10. Do not touch engine while it is running or
shortly after it is stopped because engine will be
hot enough to cause a burn.
Maintenance
1. Perform only those maintenance instructions
described in this manual. If major repairs are
ever needed or if assistance is desired, contact
your local Authorized Lawn–Boy Service
Dealer.
2. Before mower is cleaned, inspected, serviced, or
adjusted, stop engine and disconnect wire from
spark plug. Keep wire away from plug to prevent
accidental starting.
3. To assure the mower is in safe operating
condition, frequently check and keep all nuts,
bolts, and screws tight. Assure blade nut/screw is
tightened to 63 Nm (47 ft.–lbs.).
4. To reduce fire hazard, keep engine free of
excessive grease, grass, leaves, and
accumulations of dirt.
5. Allow engine to cool before storing mower in
any enclosure. Do not store mower near any
open flame or where gasoline fumes may be
ignited by a spark.
6. Do not overspeed the engine by changing
governor settings.
7. At the time of manufacture, the mower
conformed to the safety standards in effect for
rotary mowers. To ensure best performance and
continued safety certification of the mower, use
genuine Lawn–Boy replacement parts and
accessories.

EN–4
