2. Your rotary mower is a precision piece of power equipment,
not a plaything. Therefore, exercise extreme CcUtion at all
times. Your unit has been designed to perform one job: to
mow grass. Do not use it for any other purpose.
3. Never allow children under 14 years old to operite a power
mower. Children 14 years old and over should cniy operate
mower under close parental supervision. Only parsons well
acquainted with these rules of safe operation should be
allowed to use your mower.
4. Keep the area of operation clear of all persons, particularly
small children and pets. Stop engine when they are in the
vicinity of your mower to help prevent blade contad or thrown
object injury. Although the area of operation should be com
pletely cleared of foreign objects, an object maj have been
overlooked and could be accidentally thrown by tt e mower in
any direction and cause serious personal injury to :he operator
or any others allowed in the area.
PREPARATION
1. Thoroughly inspect the area where the equipm ¡nt is to be
used. Remove all stones, sticks, wire, bones and ether foreign
objects which could be picked up and thrown by tlie mower in
any direction and cause serious personal injury to :he operator
or any others allowed in the area. Plan your mowir g pattern to
avoid discharge of material toward roads, sidewalks,
bystanders and the like.
2. Always wear safety glasses or eye shields during Dperation or
while performing an adjustment or repair, to protect eyes from
foreign objects that may be thrown from the machine in any
direction.
3. Wear sturdy, rough-soled work shoes and close-1 itting slacks

minutes after running. Replace gasoline cap securdy and wipe
off any spilled gasoline before starting the engir e as it may
cause a fire or explosion.
5. Disengage the self-propelled mechanism or drh e clutch on
units so equipped before starting the engine.
6. The blade control handle Is a safety device. Never attempt to
bypass its operation. Doing so makes the safety device inoper
ative and may result in personal injury through cor tact with the
rotating blade. The blade control handle must ope ate easily in
both directions and automatically return to the disengaged
position when released.
7. Never attempt to make a wheel or cutting heigh adjustment
while the engine is running.
8. Never operate the mower in wet grass. Always be sure of your
footing. A slip and fall can cause serious personal injury. Keep
a firm hold on the handle and walk, never run. Vlow only in
daylight or in good artificial light.
9. For your safety, use the slope gauge included as part of this
manual to measure slopes before operating this unit on a
sloped or hilly area. If the slope is greater than 15° as shown
on the slope gauge, do not operate this unit on that area or
serious injury could result.
OPERATION
1. Do not change the engine governor settings or overspeed the
engine. Excessive engine speeds are dangerous.
2. Do not put hands or feet near or under rotating parts. Keep
clear of the discharge opening at all times as the rotating blade
can cause injury.
3. Stop the blade when crossing gravel drives, walks or roads.
4. After striking a foreign object, stop the engine, remove the wire
from the spark plug, and thoroughly inspect the mower for any
damage. Repair the damage before restarting and operating the
mower.
5. If the equipment should start to vibrate abnormally, stop the
engine and check immediately for the cause. Vibration is gen
erally a warning of trouble.
6. Shut the engine off and wait until the blade comes to a com
plete stop before removing the grass catcher or unclogging the
chute. The cutting blade continues to rotate for a few seconds
after the engine is shut off. Never place any part of the body in
the blade area until you are sure the blade has stopped rotat
ing.
Before cleaning, repairing or inspecting, make certain the blade

2. Slide the push nut onto the right side of the rod to
secure.

▲c WARNING I
Do not mow on inclines with a slope in excess of 15 degrees (a rise of approximately 2-1/2 feet every 10 feet). A
riding mower could overturn and cause serious injury. If operating a walk-behind mower on such a slope, it is
extremely difficult to maintain your footing and you could slip, resulting in serious injury.
Operate RIDING mowers up and down slopes, never across the face of slopes.
Operate WALK-BEHIND mowers across the face of slopf -«ver up and down slopes.
