I. GENERAL OPERATION
• Read, understand, and follow all
in struc tions on the machine and in the
manual(s) before starting. Be thor ough ly
familiar with the controls and the proper
use of the machine before starting.
• Do not put hands or feet near or under
rotating parts. Keep clear of the dis-
charge opening at all times.
• Only allow responsible individuals, who
are familiar with the in struc tions, to
operate the machine.
• Clear the area of objects such as rocks,
toys, wire, bones, sticks, etc., which could
be picked up and thrown by blade.
• Be sure the area is clear of other people
before mowing. Stop the ma chine if
anyone enters the area.
• Do not operate the mower when bare foot or wearing open sandals. Al ways
wear substantial foot wear.
• Do not pull mower backwards unless absolutely nec es sary. Always look down and behind before and while moving backwards.
• Never direct discharged material toward
anyone. Avoid discharging material
against a wall or obstruction. Material may
richochet back toward the operator. Stop
the blade when crossing gravel surfaces.
• Do not operate the mower without proper guards, plates, grass catcher or oth er
safety protective devices in place.
• See manufacturer’s instructions for
proper operation and installation of
accessories. Only use accessories approved by the manufacturer.
• Stop the blade(s) when crossing grav el
drives, walks, or roads.
• Stop the engine (motor) whenever you
leave the equip ment, before clean ing
the mower or unclogging the chute.
• Shut the engine (motor) off and wait

• Disengage the self-propelled mech a nism or drive clutch on mowers so
equipped before starting the engine.
• If the equipment should start to vi brate
abnormally, stop the engine (motor) and
check immediately for the cause. Vibration is generally a warning of trouble.
• Always wear safety goggles or safe ty glasses with side shields when op er at ing mower.
II. SLOPE OPERATION
Slopes are a major factor related to slip &
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: nev er
up and down. Exercise extreme caution
when changing direction on slopes.
• Remove obstacles such as rocks, tree
limbs, etc.
• Watch for holes, ruts, or bumps. Tall
grass can hide obstacles.
DO NOT:
• Do not trim near drop-offs, ditches or
embankments. The operator could lose
footing or balance.
• Do not trim excessively steep slopes.
• Do not mow on wet grass. Reduced
footing could cause slipping.
III. CHILDREN

Gasoline is extremely fl ammable and the
vapors are explosive.

and other sources of ignition.
• Use only an approved container.
• Never remove gas cap or add fuel with
the engine running. Allow engine to
cool before refueling.
• Never refuel the machine indoors.
• Never store the machine or fuel container where there is an open fl ame, spark
or pilot light such as a water heater or
on other appliances.
• Never fi ll containers inside a vehicle, on
a truck or trailer bed with a plastic liner.
Always place containers on the ground
away from your vehicle before fi lling.
• Remove gas-powered equipment from the
truck or trailer and refuel it on the ground. If
this is not possible, then refuel such equipment 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.
• Never overfi ll fuel tank. Replace gas
cap and tighten securely.
V. GENERAL SERVICE
• Never run machine inside a closed area.
• Never make adjustments or repairs with
the engine (motor) running. Dis con nect the
spark plug wire, and keep the wire away

attachment bolts, tight and keep equipment in good condition.
• Never tamper with safety devices.
Check their proper operation reg u lar ly.
• Keep machine free of grass, leaves, or
other debris build-up. Clean oil or fuel spillage. Allow machine to cool before storing.
• Stop and inspect the equipment if you
strike an object. Repair, if nec es sary,
before restarting.
• Never attempt to make wheel height
adjustments while the engine is running.
• Grass catcher components are sub ject to
wear, dam age, and de te ri o ra tion, which
could expose moving parts or allow objects
to be thrown. Frequently check com po nents and replace with man u fac tur er’s
recommended parts, when necessary.
• Mower blades are sharp and can cut.
Wrap the blade(s) or wear gloves, and
use extra caution when ser vic ing them.
• Do not change the engine governor setting or overspeed the engine.
• Maintain or replace safety and instruction labels, as necessary.

should not be used on or near any un im proved forest-covered, brush-covered or
grass-cov ered land unless the engine’s exhaust system is equipped with a spark
arrester meeting applicable local or state laws (if any). If a spark arrester is used, it
should be maintained in effective working order by the operator.
In the state of California the above is required by law (Section 4442 of the California Public
Resources Code). Other states may have similar laws. Federal laws apply on federal

HOW TO USE YOUR LAWN MOWER
ENGINE SPEED
Engine speed was set at the factory for
optimum performance. It is not adjustable.
ENGINE ZONE CONTROL
CAUTION: Federal regulations re quire
an engine control to be installed on this
lawn mower in order to minimize the
risk of blade contact injury. Do not un der
any circumstances attempt to de feat the
func tion of the operator con trol. The blade
turns when the engine is running.
• Your lawn mower is equipped with an
operator pres ence control bar which
requires the operator to be positioned
behind the lawn mower handle to start
and operate the lawn mower.
DRIVE CONTROL
• Self-propelling is controlled by hold-
ing the operator presence control bar
down to the handle and pulling the drive
control lever rearward to the handle.
The farther toward the handle the lever
is pulled, the faster the unit will travel.
• Forward motion will stop when either
the operator presence control bar or
drive control lever are released. To stop
forward motion without stop ping engine,
re lease the drive control lever only. Hold
op er a tor presence control bar down
against handle to con tin ue mowing
without self-propelling.
NOTE: If after releasing the drive control
the mower will not roll backwards, push
the mower forward slightly to disengage
drive wheels.
