or other reproductive harm.
WARNING: 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.
DANGER: This machine was built to be operated according to the safe operation practices in
this manual. As with any type of power equipment, carelessness or error on the part of the
operator can result in serious injury. This machine is capable of amputating fingers, hands,
toes and feet and throwing objects. Failure to observe the following safety instructions could
result in serious injury or death.
General Operation
Read this operator’s manual carefully in its entirety before
attempting to assemble this machine. Read, understand,
and follow all instructions on the machine and in the
manual(s) before operation. Keep this manual in a safe
place for future and regular reference and for ordering
replacement parts.
Thoroughly inspect the area where the equipment is to be
used. Remove all stones, sticks, wire, bones, toys and other
foreign objects, which could be tripped over or picked up
and thrown by the blade. Thrown objects can cause serious
personal injury.
Plan your mowing pattern to avoid discharge of material
toward roads, sidewalks, bystanders and the like. Also,
avoid discharging material against a wall or obstruction,
which may cause discharged material to ricochet back
toward the operator.
Be completely familiar with the controls and the proper use
of this machine before operating it.
This machine is a precision piece of power equipment,
not a plaything. Therefore, exercise extreme caution at all
times. This machine has been designed to perform one job:
to mow grass. Do not use it for any other purpose.
To help avoid blade contact or a thrown object injury,
stay in operator zone behind handles and keep children,
bystanders, helpers and pets at least 75 feet from mower
while it is in operation. Stop machine if anyone enters area.
Never allow children under 14 years of age to operate this
machine. Children 14 and over should read and understand
the instructions and safe operation practices in this manual
and on the machine and should be trained and supervised
by an adult.
Always wear safety glasses or safety goggles during
operation and while performing an adjustment or repair
to protect your eyes. Thrown objects which ricochet can
cause serious injury to the eyes.
Only responsible individuals who are familiar with these
rules of safe operation should be allowed to use this
Wear sturdy, rough-soled work shoes and close-fitting
slacks and shirts. Shirts and pants that cover the arms
and legs and steel-toed shoes are recommended. Never
operate this machine in bare feet, sandals, slippery or lightweight (e.g. canvas) shoes.
Do not put hands or feet near rotating parts or under the
cutting deck. Contact with blade can amputate fingers,
hands, toes and feet.
A missing or damaged discharge cover can cause blade
contact or thrown object injuries.
Many injuries occur as a result of the mower being pulled
over the foot during a fall caused by slipping or tripping.
Do not hold on to the mower if you are falling; release the
handle immediately.
Never pull the mower back toward you while you are
walking. If you must back the mower away from a wall or
obstruction first look down and behind to avoid tripping
and then follow these steps:
Step back from mower to fully extend your arms.
Be sure you are well balanced with sure footing.
Pull the mower back slowly, no more than half way
toward you.
Repeat these steps as needed.
Do not operate the mower while under the influence of
alcohol or drugs.
Do not engage the self-propelled mechanism on machines
so equipped while starting engine.
The blade control is a safety device. Never attempt to
bypass its operation. Doing so makes the safety device
inoperative and may result in personal injury through
contact with the rotating blade. The blade control must
operate easily in both directions and automatically return
to the disengaged position when released.
Never operate the mower in wet grass. Always be sure of
your footing. A slip and fall can cause serious personal
injury. If you feel you are losing your footing, release the
blade control handle immediately and the blade will stop
rotating within three seconds.
Mow only in daylight or good artificial light. Walk, never
Stop the blade when crossing gravel drives, walks or roads.
If the equipment should start to vibrate abnormally, stop
the engine and check immediately for the cause. Vibration
is generally a warning of trouble.
22. Shut the engine off and wait until the blade comes to
a complete stop before removing the grass catcher or
unclogging the chute. The cutting blade continues to
rotate for a few seconds after the blade control is released.
Never place any part of the body in the blade area until you
are sure the blade has stopped rotating.
When starting engine, pull cord slowly until resistance
is felt, then pull rapidly. Rapid retraction of starter cord
(kickback) will pull hand and arm toward engine faster than
you can let go. Broken bones, fractures, bruises or sprains
could result.
28. If situations occur which are not covered in this manual,
use care and good judgement. Contact Customer Support
for assistance or the name of the nearest service dealer.
Slope Operation
Slopes are a major factor related to slip and fall accidents, which
can result in severe injury. Operation on slopes requires extra
caution. If you feel uneasy on a slope, do not mow it. For your
safety, use the slope gauge included as part of this manual to
measure slopes before operating this machine on a sloped or
hilly area. If the slope is greater than 15 degrees, do not mow it.
Mow across the face of slopes; never up and down. Exercise
extreme caution when changing direction on slopes.
Watch for holes, ruts, rocks, hidden objects, or bumps
which can cause you to slip or trip. Tall grass can hide
Always be sure of your footing. A slip and fall can cause
serious personal injury. If you feel you are losing your
balance, release the blade control handle immediately and
the blade will stop rotating within three (3) seconds.
Do Not:
Do not mow near drop-offs, ditches or embankments, you
could lose your footing or balance.
Do not mow slopes greater than 15 degrees as shown on
the slope gauge.
Do not mow on wet grass. Unstable footing could cause
Tragic accidents can occur if the operator is not alert to the
presence of children. Children are often attracted to the mower
and the mowing activity. They do not understand the dangers.
Never assume that children will remain where you last saw them.
Keep children out of the mowing area and under watchful
care of a responsible adult other than the operator.
Be alert and turn mower off if a child enters the area.
Never operate mower without proper trail shield,
discharge cover, grass catcher, blade control or other safety
protective devices in place and working. Never operate
mower with damaged safety devices. Failure to do so can
result in personal injury.
Before and while moving backwards, look behind and
down for small children.
Use extreme care when approaching blind corners,
doorways, shrubs, trees, or other objects that may obscure
your vision of a child who may run into the mower.
Muffler and engine become hot and can cause a burn. Do
not touch.
Keep children away from hot or running engines. They can
suffer burns from a hot muffler.
Never attempt to make a wheel or cutting height
adjustment while the engine is running.
Only use parts and accessories made for this machine by
the manufacturer. Failure to do so can result in personal
