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 manuals before operation. Keep this manual in a safe place for reference and
ordering replacement parts
• 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.
• Never allow children to operate this machine.
• Only responsible individuals who are familiar with these rules of safe operation
should be allowed to use this machine.
• 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.
• 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.
• 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.
• Wear sturdy, rough-soled work shoes, lose-tting slacks, shirts and hearing
protection. 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
light-weight (e.g. canvas) shoes.
• Do not put hands or feet near rotating parts or under the cutting deck. Contact
with blade can amputate ngers, hands, toes and feet. Keep clear of the
discharge opening at all times.
• 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 rst look down and behind to avoid
tripping and then follow these steps:
a. Step back from mower to fully extend your arms forward.
b. Be sure you are well balanced with sure footing.
c. Pull the mower back slowly, no more than half way toward you.
d. Repeat these steps as needed.
• Do not operate the mower while under the inuence of alcohol or drugs.
• Do not engage the self-propelled mechanism on machines so equipped while
starting engine.
• The blade control handle 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
handle 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 articial light. Walk, never run.
• 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.
• Shut the engine o 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.
• Never operate mower without proper trail shield, discharge cover, grass catcher,
blade control handle 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. Check frequently for signs of wear or deterioration and
replace as needed.
• Muer and engine become hot and can cause a burn. Do not touch.
• Never attempt to make a wheel or cutting height adjustment while the engine
is running.

listed in the parts pages of this Operator’s Manual. Failure to do so can result in
personal injury.
• 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.
• If situations occur which are not covered in this manual, use care and good
judgement.
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 Guide 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.
Do:
• 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 obstacles. Uneven terrain could overturn the
machine, or cause operator to lose their balance or footing.
• 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.
• Use extra care while operating machine with a grass catcher or other
attachment(s). They can aect the stability of the machine.
Do Not:
• Do not start and stop on slopes. Avoid making sudden changes in speed or
direction. Make turns slowly and gradually.
• Do not mow near drop-os, ditches or embankments, because you could lose
your footing or balance.
• Do not mow slopes greater than 15 degrees as shown on the slope guide.
• Do not mow on wet grass. Unstable footing could cause slipping.
HAULING
Use full width ramps for loading and unloading a machine for transport.
CHILDREN
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 o if a child enters the area.
• 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.
• Keep children away from hot or running engines. They can suer burns from a
hot muer.
• 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 be trained and supervised by
an adult.
SERVICE
Safe Handling of Gasoline

OPERATION
USING YOUR LAWN MOWER
Be sure lawn is clear of stones, sticks, wire, or other objects which could damage
lawn mower or engine. Such objects could be accidently thrown by the mower in
any direction and cause serious personal injury to the operator and others. For a
healthy lawn,always cut o one-third or less of the total length of the grass. When
cutting heavy grass, reduce walking speed to allow for more eective cutting and
a proper discharge of the clippings. Do not cut wet grass. It will stick to underside
of the deck and prevent proper mulching of grass clippings. New or thick grass may
require a narrower cut or a higher cutting height.
WARNING
The operation of any lawn mower can result in foreign objects being thrown into
the eyes, which can damage your eyes severely. Always wear safety glasses while
operating the mower, or while performing any adjustments or repairs on it.
WARNING
If you strike a foreign object, stop the engine. Disconnect the spark plug wire,
thoroughly inspect mower for any damage, and repair damage before restarting
and operating. Extensive vibration of mower during operation is an indication of
damage. The unit should be promptly inspected and repaired. Refer to the Engine
Manual.
Mulching
Before mulching, remove the grass catcher and side discharge cover from the
mower. For eective mulching, do not cut wet grass. If the grass has been allowed
to grow in excess of four inches, mulching is not recommended. Use the grass
catcher to bag clippings instead.
Side Discharging
Install the side discharge cover and remove the grass catcher as the instructions in
assembly section. Keep the rear discharge door closing so that the grass clippings
can be discharged from side.
Grass Collection
1. Grass clippings will be automatically collected in bag as you run mower. Operate
mower until grass catcher is full.
2. Stop engine completely by releasing the blade control. Make sure that the unit
has come to a complete stop.
3. Clean up the grass catcher when it is full. Lift discharge door and pull the grass
catcher up and away from the mower. Dispose of the grass clippings and reinstall
