I. GENERAL OPERATION
• Read, understand, and follow all
instructions on the machine and in the manual before starting.
• Do not put hands or feet near rotating
parts or under the machine. Keep clear of the discharge opening at all times.
• Only allow responsible adults, who are
familiar with the instructions, to operate the machine.
• Clear the area of objects such as
rocks, toys, wire, etc., which could be picked up and thrown by the blades.
• Be sure the area is clear of bystand-
ers before operating. Stop machine if anyone enters the area.
• Never carry passengers.
• Do not mow in reverse unless abso-
lutely necessary. Always look down and behind before and while backing.
• Never direct discharged material toward anyone. Avoid discharging material against a wall or obstruction. Material may ricochet back toward the operator. Stop the blades when cross­ing gravel surfaces.
• Do not operate machine without the entire grass catcher, discharge guard, or other safety devices in place and working.
• Slow down before turning.
• Never leave a running machine unattended. Always turn off blades, set parking brake, stop engine, and remove keys before dismounting.
• Disengage blades when not mowing. Shut off engine and wait for all parts to come to a complete stop before clean­ing the machine, removing the grass catcher, or unclogging the discharge guard.
• Operate machine only in daylight or good artifi cial light.
• Do not operate the machine while under the infl uence of alcohol or drugs.
• Watch for traffi c when operating near or crossing roadways.
• Use extra care when loading or unload­ing the machine into a trailer or truck.
• Always wear eye protection when oper­ating machine.
• Data indicates that operators, age 60 years and above, are involved in a large percentage of riding mower-re­lated injuries. These operators should evaluate their ability to operate the riding mower safely enough to protect themselves and others from serious injury.
• Follow the manufacturer’s recommen­dation for wheel weights or counter­weights.
• Keep machine free of grass , leaves or other debris build-up which can touch hot exhaust / engine parts and burn. Do not allow the mower to plow leaves or other debris which can cause build-up to occur. Clean any oil or fuel spillage before operating or storing the machine. Allow machine to cool before storage.

SAFETY RULES
II. SLOPE OPERATION
Slopes are a major factor related to loss of control and tip-over accidents, which can result in severe injury or death. Opera­tion on all slopes requires extra caution. If you cannot back up the slope or if you feel uneasy on it, do not mow it.
• Mow up and down slopes, not across.
• Watch for holes, ruts, bumps, rocks, or other hidden objects. Uneven terrain could overturn the machine. Tall grass can hide obstacles.
• Choose a low ground speed so that you will not have to stop or shift while on the slope.
• Do not mow on wet grass. Tires may lose traction.
Always keep the machine in gear when
going down slopes. Do not shift to neutral and coast downhill.
• Avoid starting, stopping, or turning on a slope. If the tires lose traction, dis­engage the blades and proceed slowly straight down the slope.
• Keep all movement on the slopes slow and gradual. Do not make sudden changes in speed or direction, which could cause the machine to roll over.
• Use extra care while operating ma­chine with grass catchers or other at­tachments; they can affect the stability of the machine. Do no use on steep slopes.
• Do not try to stabilize the machine by putting your foot on the ground.
• Do not mow near drop-offs, ditches, or embankments. The machine could suddenly roll over if a wheel is over the edge or if the edge caves in.
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 mowing area and in the watchful 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.
• Never carry children, even with the blades shut off. They may fall off and be seriously injured or interfere with safe machine operation. Children who have been given 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.
• Use extra care when approaching blind corners, shrubs, trees, or other objects that may block your view of a child.
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 equipment.
• 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 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 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 fl ame, spark, or pilot light such as on a water heater or other appliances.
• Never fi ll 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 fi lling.
3
SAFETY RULES
• 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.
• Keep the nozzle in contact with the rim of the fuel tank or container opening at all times until fueling is complete. Do not use a nozzle lock-open device.
• If fuel is spilled on clothing, change clothing immediately.
• Never overfi ll fuel tank. Replace gas cap and tighten securely.
GENERAL SERVICE
• Never operate machine in a closed area.
• Keep all nuts and bolts tight to be sure the equipment is in safe working condi­tion.
• Never tamper with safety devices.
Check their proper operation regularly.
• Keep machine free of grass, leaves, or other debris build-up. Clean oil or fuel spillage and remove any fuel-soaked debris. Allow machine to cool before storing.
• If you strike a foreign object, stop and inspect the machine. Repair, if neces­sary, before restarting.
• Never make any adjustments or repairs with the engine running.
• Check grass catcher components and the discharge guard frequently and replace with manufacturer’s recom­mended 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.
• Be sure the area is clear of bystand­ers before operating. Stop machine if anyone enters the area.
• Never carry passengers.
• Do not mow in reverse unless abso­lutely necessary. Always look down and behind before and while backing.
• Never carry children, even with the blades shut off. They may fall off and be seriously injured or interfere with safe machine operation. Children who have been given rides in the past may suddenly appear in the mowing area for another ride and be run over or backed over by the machine.
• Keep children out of the mowing area and in the watchful 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.
