Safe Operation Practices for Walk-Behind Mowers
IMPORTANT: THIS CUTTING MACHINE IS CAPABLE OF AMPUTATING HANDS AND FEET AND THROWING OBJECTS. FAILURE
TO OBSERVE THE FOLLOWING SAFETY INSTRUCTIONS COULD RESULT IN SERIOUS INJURY OR DEATH.
SAFETY RULES
I. GENERAL OPERATION
• Read, understand, and follow all instructions on the
machine and in the manual(s) before starting. Be thor-
oughly 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 discharge opening at all times.
• Only allow responsible individuals, who are familiar
with the instructions, to operate the machine.
• Clear the area of objects such as rocks, toys, wire,
bones,sticks,etc., whichcouldbepickedupandthrown
by the blade.
• Be sure the area is clear of other people before mow-
ing. Stop machine if anyone enters the area.
• Do not operate the mower when barefoot or wearing
open sandals. Always wear substantial foot wear.
• Do not pull mower backwards unless absolutely nec-
essary. Alwayslookdownandbehindbeforeandwhile
moving backwards.
• Never direct discharged material toward anyone.
Avoid discharging material against a wall or obstruc-
tion. Materialmayrichochetbacktowardtheoperator.
Stop the blade when crossing gravel surfaces.
• Do not operate the mower without proper guards,
plates,grasscatcherorothersafetyprotectivedevices
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 gravel drives, walks,
or roads.
• Stoptheengine(motor)wheneveryouleavetheequip-
ment, before cleaning the mower or unclogging the
chute.
• Shuttheengine(motor)offandwaituntilthebladecomes
to complete stop before removing grass catcher.
• Mow only in daylight or good artificial light.
• Do not operate the machine while under the influence
of alcohol or drugs.
• Neveroperatemachineinwetgrass. Alwaysbesureof
your footing: keep a firm hold on the handle and walk;
never run.
• Disengagetheself-propelledmechanismordriveclutch
onmowerssoequippedbeforestartingtheengine(motor).
• If the equipment should start to vibrate abnormally,
stop the engine (motor) and check immediately for the
cause. Vibration is generally a warning of trouble.
• Alwayswearsafetygogglesorsafetyglasseswithside
shields when operating mower.
II. SLOPE OPERATION
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:
• Mowacrossthefaceofslopes:neverupanddown. Exer-
ciseextremecautionwhenchangingdirectiononslopes.
• 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.
• Donotmowonwetgrass.Reducedfootingcouldcause
slipping.
III. CHILDREN
Tragic accidents can occur if the operator is not alert to
the presence of children. Children are often attracted to
the machine and the mowing activity. Never assume that
children will remain where you last saw them.
• Keep children out of the trimming area and under the
watchful care of another responsible adult.
• Be alert and turn machine off if children enter the
area.
• Before and while walking backwards, look behind and
down for small children.
• Never allow children to operate the machine.
• Useextracarewhenapproachingblindcorners,shrubs,
trees, or other objects that may obscure vision.
IV. SAFE HANDLING OF GASOLINE
Use extreme care in handling gasoline. Gasoline is ex-
tremely flammable and the vapors are explosive.
• Extinguishallcigarettes,cigars,pipesandothersources
of ignition.
• Use only an approved container.
• Neverremove gas cap oradd fuel with theengine run-
ning. Allow engine to cool before refueling.

TO STOP ENGINE
• To stop engine, release operator presence control
bar.
TO START ENGINE
NOTE: Due to protective coatings on the engine, a small
amount of smoke may be present during the initial use of
the product and should be considered normal.
NOTE: Your engine is equipped with an automatic choke
system. No priming or choking is required before start-
ing.
• To start engine, hold operator presence control bar
down to the handle and pull starter handle quickly. Do
not allow starter rope to snap back.
MOWING TIPS
CAUTION:Donotusede-thatcherblade
attachments on your mower. Such at-
tachments are hazardous, will damage
yourmowerandcouldvoidyourwarranty.
• Under certain conditions, such as very tall grass, it
may be necessary to raise the height of cut to reduce
pushingeffortandtokeepfromoverloadingtheengine
and leaving clumps of grass clippings. It may also be
necessarytoreducegroundspeed and/orrunthelawn
mower over the area a second time.
• For extremely heavy cutting, reduce the width of cut
by overlapping previously cut path and mow slowly.
• For better grass bagging and most cutting conditions,
the engine speed should be set in the fast position.
• Pores in cloth grass catchers can become filled with
dirt and dust with use and catchers will collect less
grass. To prevent this, regularly hose catcher off with
water and let dry before using.
• Keep top of engine around starter clear and clean of
grassclippings andchaff. Thiswillhelpengineairflow
and extend engine life.
MULCHING MOWING TIPS
IMPORTANT: FOR BEST PERFORMANCE, KEEP MOWER
HOUSING FREE OF BUILT-UP GRASS AND TRASH. SEE
“CLEANING”INTHEMAINTENANCESECTIONOFTHISMANUAL.
• The special mulching blade will recut the grass clip-
pings many times and reduce them in size so that as
they fall onto the lawn they will disperse into the grass
andnotbenoticed. Also,themulchedgrasswillbiode-
gradequicklytoprovidenutrientsfor the lawn. Always
mulch with your highest engine (blade) speed as this
will provide the best recutting action of the blades.
• Avoidcuttingyourlawnwhenitiswet. Wetgrasstends
toformclumpsandinterfereswiththemulchingaction.
The best time to mow your lawn is the early afternoon.
At this time the grass has dried, yet the newly cut area
will not be exposed to direct sunlight.
• For best results, adjust the lawn mower cutting height
so that the lawn mower cuts off only the top one-third
of the grass blades (See Fig. 12). If the lawn is over-
grown it will be necessary to raise the height of cut to
reduce pushing effort and to keep from overloading
the engine and leaving clumps of mulched grass. For
extremelyheavymulching, reduce yourwidthofcutby
overlapping previously cut path and mow slowly.
OPERATION
• Certaintypesofgrassandgrassconditionsmayrequire
that an area be mulched a second time to completely
hide the clippings. When doing a second cut, mow
across (perpendicular) to the first cut path.
• Change your cutting pattern from week to week. Mow
northtosouthoneweektheneasttowestthenextweek.
Thiswillhelp prevent matting and grainingofthe lawn.
