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 oper-
ate 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 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 opera-
tor.  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 ap-
proved 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 until 

the blade comes to complete stop before 
removing grass catcher.

•   Mow only in daylight or good artifi cial 

light.

•   Do not operate the machine while under 

the infl uence of alcohol or drugs.

•   Never operate machine in wet grass. 

Always be sure of your footing: keep a 
fi rm hold on the handle; walk, never run.

•   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. Vibra-
tion 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 in-
jury. 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 foot-

ing could cause slipping.

III. CHILDREN

Tragic accidents can occur if the op er a tor 
is not alert to the presence of children. 
Children are often attracted to the ma chine 
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 an oth er 
re spon si ble adult.

•   Be alert and turn machine off if chil dren 

enter the area.

•   Before and while walking back wards, 

look behind and 

down for small chil dren. 

•   Never allow children to operate the ma-

chine.

•   Use extra care when approaching blind 

corners, shrubs, trees, or other objects 
that may obscure vision.

IV. SAFE HANDLING OF GASOLINE

Use extreme care in handling gasoline.  
Gasoline is extremely fl ammable and the 
vapors are explosive.
•   Extinguish all cigarettes, cigars, pipes 

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 contain-

er where there is an open fl ame, spark 
or pilot light such as a water heater or on 
other appliances.
