Safety

This machine meets or exceeds the safety specifications of the American National Standards Institute B71.1-2003 in effect at the time of production. However, improper use or maintenance by the operator or owner can result in injury. To reduce the potential for injury, comply with these safety instructions and always pay attention to the safety alert symbol, which means CAUTION, WARNING, or DANGER-"personal safety instruction." Failure to comply with the instruction may result in personal injury or death.

Safe Operating Practices

The following instructions are from ANSI standard B71.1-2003. This product is capable of amputating hands and feet and throwing objects. Always follow all safety instructions to avoid serious injury or death.

General Operation

• Read, understand, and follow all instructions in the operator’s manual and on the machine before starting.

• Do not place hands or feet near rotating parts or under the machine. Keep clear of the discharge opening at all times.

• Allow only 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 blade.

• Be sure the area is clear of other people before mowing. Stop the 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 up.

• Be aware of the mower discharge direction and do not point it at 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 the mower without either the entire grass collection system or the discharge deflector in place.

• Be alert, slow down and use caution when making turns. Look behind and to the side before changing directions.

• Never leave a running machine unattended. Always turn off blades, engage parking brake, stop engine, and remove key before dismounting.

• Turn off blades when not mowing. Stop the engine, wait for all parts to come to a complete stop, engage parking brake, and remove key before cleaning the machine, removing the grass or unclogging the deflector.

• Operate the machine only in daylight or good artificial light.

• Do not operate the machine while under the influence of alcohol or drugs.

• Watch for traffic 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 the mower.

• 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.

• Always follow the recommendations for wheel weights or counterweights.

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.

• Do not mow slopes greater than 15 degrees.

• Watch for ditches, holes, rocks, dips, and rises that change the operating angle, as rough terrain could overturn the machine.

• Choose a low ground speed so you will not have to stop while operating on a slope.

• Do not mow slopes when grass is wet. Slippery conditions reduce traction and could cause sliding and loss of control.

• Reduce speed and use extreme caution on slopes.

• Do not make sudden turns or rapid speed changes.

• Remove or mark obstacles such as rocks, tree limbs, etc. from the mowing area. Tall grass can hide obstacles.

• Avoid sudden starts when mowing uphill because the mower may tip backwards.

• Be aware that loss of traction may occur going downhill. Weight transfer to the front wheels may cause drive wheels to slip and cause loss of braking and steering.

• Always avoid sudden starting or stopping on a slope. If tires lose traction, disengage the blades and proceed slowly off the slope.

• Use extreme care with grass collection systems or other attachments. These can change the stability of the machine and cause loss of control.

• Do not try to stabilize the machine by putting your foot on the ground.

• Do not mow near drop-offs, ditches, steep banks or water. Wheels dropping over edges can cause rollovers, which may result in serious injury, death or drowning.

• Use a walk behind mower and/or a hand trimmer near drop-offs, ditches, steep banks or water.

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 under the watchful care of another responsible adult, not the operator.

• Be alert and turn the machine off if children enter the area.

• Before and while backing or changing direction, look behind, down, and side-toside for small children.

• Never carry children, even with the blades 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 mower.

• Never allow children to operate the machine.

• Use extra care when approaching blind corners, shrubs, trees, the end of a fence or other objects that may obscure vision.

Towing

• This machine does not make any provisions for towing.

Service

Safe Handling of Gasoline: To avoid personal injury or property damage,

use extra care when handling gasoline and other fuels. They are flammable and the vapors are explosive.

• Extinguish all cigarettes, cigars, pipes and other sources of ignition.

• Use only an approved container.

• Never remove the gas cap or add fuel

when the engine is running. Allow the engine to cool before refueling.

• Never refuel the machine indoors.

• Never store the machine or fuel container

inside where there is an open flame, such as near a water heater or furnace.

• Never fill containers inside a vehicle or on a truck or trailer with a plastic liner. Always place containers on the ground away from your vehicle before 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.

• Keep the nozzle in contact with the rim of the fuel tank or container opening at all times until the fueling is complete. Do not use a nozzle lock-open device.

• If fuel is spilled on clothing, change clothing immediately.

• Never overfill the fuel tank. Replace gas cap and tighten securely.

General Service:

• Never run a machine inside a closed area.

• Keep nuts and bolts tight, especially the

blade attachment bolts. Keep equipment in good condition.

• Never tamper with safety devices. Check their proper operation regularly.

• Keep the machine free of grass, leaves, or other debris build-up. Clean up oil or fuel spillage and fuel soaked debris. Allow the machine to cool before storing.

• Stop and inspect the equipment if you strike an object. Repair, if necessary, before restarting.

• Never make any adjustments or repairs with the engine running.

• Grass collection system components are subject to wear, damage and deterioration, which could expose moving parts or allow objects to be thrown. Frequently check components and replace with manufacturers’ recommended parts, when necessary.

• Mower blades are sharp and can cut. Wrap the blades or wear gloves, and use extra caution when servicing them.

• Check for proper brake operation frequently. Adjust and service as required.

• Maintain or replace safety and instruction decals as necessary.

• Use only genuine Toro replacement parts to ensure that original standards are maintained.

Toro Riding Mower Safety

The following list contains safety information specific to Toro products or other safety information that you must know that is not included in the ANSI standards.

• Engine exhaust contains carbon monoxide, which is an odorless, deadly poison that can kill you. Do not run engine indoors or in an enclosed area.

• Stop the engine, wait for all moving parts to stop, engage parking brake, disconnect spark plug wire(s) and remove key before performing any service, repairs, maintenance or adjustments.

• Keep hands, feet, hair, and loose clothing away from attachment discharge area, underside of mower and any moving parts while engine is running.

• Do not touch equipment or attachment parts which may be hot from operation. Allow to cool before attempting to maintain, adjust or service.

• Battery acid is poisonous and can cause burns. Avoid contact with skin, eyes, and clothing. Protect your face, eyes, and clothing when working with a battery.

• Battery gases can explode. Keep cigarettes, sparks and flames away from battery.

• Use only Toro approved attachments. Warranty may be voided if used with unapproved attachments.

• If loading the machine onto a trailer or truck, use a single, full-width ramp only. The ramp angle should not exceed 15 degrees.

Note: The left and right sides of the machine are determined while sitting in the seat in the normal operating position.

Ignition Switch

The ignition switch has three positions, Off, Run and Start. The key will turn to Start and move back to Run upon release. Turning the key to the Off position will stop the engine; however, always remove the key when leaving the machine to prevent someone from accidentally starting the engine (Figure 5).

Blade Control Switch (Power Take-Off)

The blade control switch, represented by a power take-off (PTO) symbol, engages and disengages power to the mower blades (Figure 5).

Throttle Control

The throttle is used to control engine speed. Moving throttle lever forward will increase engine speed and moving throttle lever to the rear will decrease engine speed. Moving the throttle forward into the detent is full throttle (Figure 5).

Motion Control Levers and Parking Brake

The motion control levers are speed sensitive controls of independent wheel motors. Moving a lever forward or backward turns the wheel on the same side forward or in reverse; wheel speed is proportional to the amount the lever is moved. Moving the control levers outward from the center position locks them in the neutral position. Engaging the parking brake lever allows the operator to exit the machine (Figure 13). Always position the motion control levers into the neutral position and engage the park brake lever when you stop the machine or leave it unattended.

Height-of-Cut Foot Lever

The height of cut lever allows the operator to lower and raise the deck from the seated position. When the lever is moved forward, away from the operator the deck is raised from the ground and when moved back, towards the operator it is lowered toward the ground. Only adjust the height of cut while machine is not moving (Figure 14).

Choke Control

The choke is used to aid in starting a cold engine. DO NOT run a warm engine with the choke in the “ON” position. Moving the choke lever forward will put the choke in the “ON” position and moving the choke lever to the rear will put the choke in the “OFF” position (Figure 5).
