SAFETY RULES  
Safe Operation Practices for Ride-On Mowers  
GENERAL SERVICE  
III. CHILDREN  
Never operate machine in a closed area.  
Keep all nuts and bolts tight to be sure the equipment  
is in safe working condition.  
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.  
Never tamper with safety devices. Check their proper  
operation regularly.  
Keepchildrenoutofthemowingareaandinthewatchful  
care of a responsible adult other than the operator.  
Be alert and turn machine off if a child enters the  
area.  
Before and while backing, look behind and down for  
small children.  
Nevercarrychildren,evenwiththebladesshutoff.They  
may fall off and be seriously injured or interfere with  
safemachineoperation.Childrenwhohavebeengiven  
rides in the past may suddenly appear in the mowing  
area for another ride and be run over or backed over  
by the machine.  
Never allow children to operate the machine.  
Useextracarewhenapproachingblindcorners,shrubs,  
trees, or other objects that may block your view of a  
child.  
Keep machine free of grass, leaves, or other debris  
build-up. Cleanoilorfuelspillageandremoveanyfuel-  
soaked debris. Allow machine to cool before storing.  
If you strike a foreign object, stop and inspect the  
machine. Repair, if necessary, before restarting.  
Nevermakeanyadjustmentsorrepairswiththeengine  
running.  
Check grass catcher components and the discharge  
guard frequently and replace with manufacturer's rec-  
ommended parts, when necessary.  
Mower blades are sharp. Wrap the blade or wear  
gloves, and use extra caution when servicing them.  
Check brake operation frequently. Adjust and service  
as required.  
Maintain or replace safety and instruction labels, as  
necessary.  
IV. TOWING  
Tow only with a machine that has a hitch designed for  
towing. Do not attach towed equipment except at the  
hitch point.  
Follow the manufacturer's recommendation for weight  
limits for towed equipment and towing on slopes.  
Never allow children or others in or on towed equip-  
ment.  
Be sure the area is clear of bystanders before operat-  
ing. Stop machine if anyone enters the area.  
Never carry passengers.  
Do not mow in reverse unless absolutely necessary.  
Alwayslookdownandbehindbeforeandwhilebacking.  
Nevercarrychildren,evenwiththebladesshutoff.They  
may fall off and be seriously injured or interfere with  
safemachineoperation.Childrenwhohavebeengiven  
rides in the past may suddenly appear in the mowing  
area for another ride and be run over or backed over  
by the machine.  
Keepchildrenoutofthemowingareaandinthewatchful  
care of a responsible adult other than the operator.  
Be alert and turn machine off if a child enters the  
area.  
Before and while backing, look behind and down for  
small children.  
Mow up and down slopes (15° Max), not across.  
Choose a low ground speed so that you will not have  
to stop or shift while on the slope.  
Avoid starting, stopping, or turning on a slope. If the  
tires lose traction, disengage the blades and proceed  
slowly straight down the slope.  
If machine stops while going uphill, disengage blades,  
shift into reverse and back down slowly.  
Do not turn on slopes unless necessary, and then, turn  
slowly and gradually downhill, if possible.  
On slopes, the weight of the towed equipment may  
cause loss of traction and loss of control.  
Travel slowly and allow extra distance to stop.  
V. SERVICE  
SAFE HANDLING OF GASOLINE  
To avoid personal injury or property damage, use extreme  
careinhandlinggasoline. Gasolineisextremelyflammable  
and the vapors are explosive.  
Extinguish all cigarettes, cigars, pipes, and other  
sources of ignition.  
Use only approved gasoline container.  
Never remove gas cap or add fuel with the engine  
running. Allow engine to cool before refueling.  
Never fuel the machine indoors.  
Never store the machine or fuel container where there  
is an open flame, spark, or pilot light such as on a water  
heater or other appliances.  
Never fill containers inside a vehicle or on a truck or  
trailer bed with plastic liner. Always place containers  
on the ground away from your vehicle when filling.  
Remove gas-powered equipment from the truck or  
trailer and refuel it on the ground. If this is not possible,  
then refuel such equipment with a portable container,  
rather than from a gasoline dispenser nozzle.  
Keepthenozzleincontactwiththerimofthefueltankor  
container opening at all times until fueling is complete.  
Do not use a nozzle lock-open device.  
Iffuelisspilledonclothing,changeclothingimmediately.  
Never overfill fuel tank. Replace gas cap and tighten  
securely.
