Congratulations on purchasing a superior-quality piece of lawn and garden equipment. Our products are designed and manufactured to

meet or exceed all industry standards for safety. Power equipment is only as safe as the operator. If it is misused, or

not properly maintained, it can be dangerous! Remember, you are responsible for your safety and that of those around you.

Use common sense, and think through what you are doing. Ifyou

are not sure that the task you are about to perform can be safely done with the equipment you have chosen, ask a

professional: contact your local authorized dealer.

The operator's manual contains important safety information you need to be aware of BEFORE you operate your unit as well as DURING operation.

Safe operating techniques, an explanation of the product's features and controls, and maintenance information is included to help you get the

most out of your equipment investment. Be sure to completely read the Safety Rules and Information found on

the following pages. Also completely read the Operation section.

Tragic accidents can occur with children. Do not allow them anywhere near the area of operation. Children are

often attracted to the unit and mowing activity. Never assume that children will remain where you last saw them.

If there is a risk that children may enter the area where you

are mowing, have another responsible adult watch them. DO NOT GIVE CHILDREN RIDES ON THIS UNIT! This

encourages them to come near the unit in the future while it is running, and they could be seriously hurt. They may then approach the unit for a ride when you are not expecting it,

and you may run over them.

RSVSP88

Do not mow in reverse unless absolutely necessary. Always look

down and behind before and while traveling in reverse

even with the mower blades disengaged.

,peOperation

You could be seriously injured or even killed if you use this unit on too steep an incline. Using the unit on a slope that is too steep or where

you don't have adequate traction can cause you to lose control or roll over.

A good rule of thumb is to not operate on any slope you cannot back up

(in 2-wheel drive mode). You should not operate on inclines with a

slope greater than a 3.5 foot rise over a 20 foot length. Always drive up

3.5

and down slopes: never cross the face. Also note that the surface you are driving on can greatly impact stability

and control. Wet grass or icy pavement can seriously affect your ability to control the unit.

If you feel unsure about operating the unit on an incline, don't do it. It's not worth the risk.

Moving

This equipment has many moving parts that can injure you or someone else.

However, if you are seated inthe seat properly, and follow all the rules in this book, the unit is safe to operate.

The mower deck has spinning mower blades that can amputate hands and feet.

Do not allow anyone near the equipment while it is running!

To help you, the operator, use this equipment safely, it is equipped with an operator-present safety system. Do NOT attempt to alter or bypass the system.

See your dealer immediately if the system does not pass all the safety interlock system tests found in this manual.

OperatorSafety,

Thrown ects

This unit has spinning mower blades. These blades can pick up and throw debris that could seriously injure a bystander. Be sure to clean up the area to

be mowed BEFORE you start mowing. Do not operate this unit without the entire grass catcher or discharge guard

(deflector) in place. Also, do not allow anyone in the area while the unit is running! If someone

does enter the area, shut the unit off immediately until they leave.

Gasoline is extremely flammable. Its vapors are also extremely flammable

and can travel to distant ignition sources. Gasoline must only be used as a fuel, not as a solvent or cleaner. It should never be stored any place where

its vapors can build up or travel to an ignition source like a pilot light. Fuel belongs in an approved, plastic, sealed gas can, or in the tractor fuel tank

with the cap securely closed. Spilled fuel needs to be cleaned up immedi- ately.

Proper maintenance is critical to the safety and performance of your unit. Be sure to perform the maintenance procedures listed in this manual, espe-

cially periodically testing the safety system.

OperatorSafety

Read these safety rules and follow them closely. Failure to obey these rules could result in loss of control of unit, severe personal injury or death to you, or bystanders, or damage to property or equipment. This mowing deck is capable of amputating hands and feet and throwing objects.

The triangle _ in text signifies important cautions or warnings which must be followed.

GENERAL OPERATION

= Read, understand, and follow all instructions in the

manual and on the unit 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 unit (local regulations can restrict operator age).

= Clear the area of objects such as rocks, toys, wire,

etc., which could be picked up and thrown by the blade(s).

= Be sure the area is clear of other people before mow-

ing. Stop the unit ifanyone enters the area. = Never carry passengers. = Do not mow in reverse unless absolutely necessary.

Always look down and behind before and while travel-

ling in reverse. = Never direct discharge material toward anyone.

Avoid discharging material against a wall or obstruc- tion. Material may ricochet back toward the operator.

Stop the blade(s) when crossing gravel surfaces.

Do not operate the machine without the entire grass

catcher, discharge guard (deflector), or other safety devices in place.

• Slow down before turning.

• Never leave a running unit unattended. Always disen-

gage the PTO, set parking brake, stop engine, and

remove keys before dismounting.

• Disengage blades (PTO) 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 the machine only in daylight or good artificial

light.

• Do not operate the unit 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 unit into a trailer or truck.

Always wear eye protection when operating this unit.

Data indicates that operators, age 60 years and above, are involved in a large percentage of power equipment-related injuries. These operators should evaluate their ability to operate the equipment safely enough to protect themselves and others from injury.

Follow the manufacturer's recommendations for wheel weights or counterweights.

Keep in mind the operator is responsible for accidents occurring to other people or property. All drivers should seek and obtain professional and practical instruction. Always wear substantial footwear and trousers.

Never operate when barefoot or wearing sandals.

Before using, always visually check that the blades and blade hardware are present, intact, and secure.

Replace worn or damaged parts.

Disengage attachments before: refueling, removing an attachment, making adjustments (unless the adjustment can be made from the operator's posi- tion). When the machine is parked, stored, or left unattend- ed, lower the cutting means unless a positive

mechanical lock is used.

Before leaving the operator's position for any reason, engage the parking brake (if equipped), disengage the PTO, stop the engine, and remove the key. To reduce fire hazard, keep the unit free of grass,

leaves, & excess oil. Do not stop or park over dry

leaves, grass, or combustible materials.

It is a violation of California Public Resource Code Section 4442 to use or operate the engine on or near

any forest-covered, brush-covered, or grass-covered

land unless the exhaust system is equipped with a spark arrester meeting any applicable local or state

laws. Other states or federal areas may have similar

laws.

TRANSPORTING AND STORAGE

= When transporting the unit on an open trailer, make

sure it is facing forward, in the direction of travel. If

the unit is facing backwards, wind lift could damage the unit.

Always observe safe refueling and fuel handling prac- tices when refueling the unit after transportation or

storage. Never store the unit (with fuel) in an enclosed poorly

ventilated structure. Fuel vapors can travel to an

ignition source (such as a furnace, water heater, etc.)

and cause an explosion. Fuel vapor is also toxic to

humans and animals.

Always follow the engine manual instructions for

storage preparations before storing the unit for both

short and long term periods.

Always follow the engine manual instructions for

proper start-up procedures when returning the unit to

service.

Never store the unit or fuel container inside where there is an open flame or pilot light, such as in a water heater. Allow unit to cool before storing.

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 can- not back up the slope or ifyou feel uneasy on it, do not

operate on it. Control of a walk-behind or ride-on machine sliding on a

slope will not be regained by the application of the brake. The main reasons for loss of control are: insufficient tire

grip on the ground, speed too fast, inadequate braking, the

type of machine is unsuitable for its task, lack of awareness

of the ground conditions, incorrect hitching and load distrib- ution.

Mow up and down slopes, not across. Watch for holes, ruts, or bumps. Uneven terrain could overturn the unit. Tall grass can hide obstacles.

Choose a slow speed so that you will not have to

stop or change speeds while on the slope.

Do not mow on wet grass. Tires may loose traction. Always keep unit in gear especially when traveling down slopes. Do not shift to neutral and coast down-

hill. Avoid starting, stopping, or turning on a slope. If tires

lose traction, disengage the blade(s) and proceed

slowly straight down the slope.

Keep all movement on slopes slow and gradual. Do

not make sudden changes in speed or direction, which could cause the machine to rollover.

Use extra care while operating machines with grass catchers or other attachments; they can affect the

stability of the unit. Do not use on steeps slopes.

Do not try to stabilize the machine by putting your foot on the ground (ride-on units).

Do not mow near drop-offs, ditches, or embank-

ments. The mower could suddenly turn over if a wheel is over the edge of a cliff or ditch, or if an edge

caves in.

Do not use grass catchers on steep slopes.

Do not mow slopes you cannot back up them.

See your authorized dealer/retailer for recommenda- tions of wheel weights or counterweights to improve

stability.

• Remove obstacles such as rocks, tree limbs, etc.

• Use slow speed. Tires may lose traction on slopes even through the brakes are functioning properly.

• Do not turn on slopes unless necessary, and then,

turn slowly and gradually downhill, if possible.

WARNING

Never operate on slopes greater than 17.6 percent (10°) which is a rise of 3-1/2 feet (106 cm) vertically in

20 feet (607 cm) horizontally. When operating on slopes use additional wheel

weights or counterweights. See your dealer/retailer to determine which weights are available and appropriate for your unit.

Select slow ground speed before driving onto slope.

In addition to front weights, use extra caution when

operating on slopes with rear-mounted grass catchers.

Mow UP and DOWN the slope, never across the

face, use caution when changing directions and DO

NOT START OR STOP ON SLOPE.

CHILDREN

Tragic accidents can occur if the operator is not alert to the presence of children. Children are often attracted to the

unit 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.

Be alert and turn unit off if children enter the area. Before and during reverse operation, look behind and

down for small children.

Never carry children, even with the blade(s) off. They may fall off and be seriously injured or interfere with

safe unit 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 unit. Use extra care when approaching blind corners,

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

EMISSIONS

Engine exhaust from this product contains chemicals known, in certain quantities, to cause cancer, birth

defects, or other reproductive harm.

Look for the relevant Emissions Durability Period and

Air Index information on the engine emissions label.

TOWED EQUIPMENT (RIDE-ON UNITS)

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 recommendations for

weight limit for towed equipment and towing on

slopes. Never allow children or others in or on towed equip-

ment. 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.

Do not shift to neutral and coast down hill.

IGNITION SYSTEM

= This spark ignition system complies with Canadian

standard ICES-O02.

OperatorSafety

SERVICE AND MAINTENANCE

Safe Handling of Gasoline

Extinguish all cigarettes, cigars, pipes, and other

sources of ignition.

Use only approved gasoline containers. Never remove the gas cap or add fuel with the engine running. Allow the 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

near a water heater or other appliance. Never fill containers inside a vehicle or on a truck bed

with a plastic bed 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 possi- ble, then refuel such equipment on a trailer with a portable container, rather than from a gasoline dis- penser nozzle.

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

if fuel is spilled on clothing, change clothing immedi- ately.

Never over-fill the fuel tank. Replace gas cap and tighten securely.

Use extra care in handling gasoline and other fuels. They are flammable and vapors are explosive.

If fuel is spilled, do not attempt to start the engine but

move the machine away from the area of spillage and avoid creating any source of ignition until fuel vapors

have dissipated.

Replace all fuel tank caps and fuel container caps securely.

Service & Maintenance

Never run the unit in an enclosed area where carbon

monoxide fumes may collect.

Keep nuts and bolts, especially blade attachment bolts, tight and keep equipment in good condition.

Never tamper with safety devices. Check their proper operation regularly and make necessary repairs if they are not functioning properly.

Keep unit free of grass, leaves, or other debris build-

up. Clean up oil or fuel spillage, and remove any fuel- soaked debris. Allow machine to cool before storage.

If you strike an object, stop and inspect the machine.

Repair, if necessary, before restarting.

Never make adjustments or repairs with the engine

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 instructions labels, as

necessary.

Do not remove the fuel filter when the engine is hot as spilled gasoline may ignite. Do not spread fuel line clamps further than necessary. Ensure clamps grip

hoses firmly over the filter after installation.

Do not use gasoline containing METHANOL, gasohol containing more than 10% ETHANOL, gasoline addi- tives, or white gas because engine/fuel system dam- age could result.

If the fuel tank must be drained, it should be drained

outdoors.

Replace faulty silencers/mufflers. Use only factory authorized replacement parts when

making repairs. Always comply with factory specifications on all set- tings and adjustments.

Only authorized service locations should be utilized for major service and repair requirements.

Never attempt to make major repairs on this unit

unless you have been properly trained. Improper ser- vice procedures can result in hazardous operation,

equipment damage and voiding of manufacturer's warranty.

On multiple blade mowers, take care as rotating one

blade can cause other blades to rotate.

Do not change engine governor settings or over-

speed the engine. Operating the engine at excessive

speed can increase the hazard of personal injury.

Disengage drive attachments, stop the engine,

remove the key, and disconnect the spark plug wire(s) before: clearing attachment blockages and chutes, performing service work, striking an object, or

if the unit vibrates abnormally. After striking an object, inspect the machine for damage and make

repairs before restarting and operating the equip-

ment.

Never place hands near the moving parts, such as a

hydro pump cooling fan, when the tractor is running.

(Hydro pump cooling fans are typically located on top of the transaxle).

Units with hydraulic pumps, hoses, or motors: WARN-

ING: Hydraulic fluid escaping under pressure may

have sufficient force to penetrate skin and cause seri- ous injury. If foreign fluid is injected into the skin it

must be surgically removed within a few hours by a doctor familiar with this form of injury or gangrene

may result. Keep body and hands away from pin

holes or nozzles that eject hydraulic fluid under high

pressure. Use paper or cardboard, and not hands, to

search for leaks. Make sure all hydraulic fluid con-

nections are tight and all hydraulic hoses and lines are in good condition before applying pressure to the

system. If leaks occur, have the unit serviced imme- diately by your authorized dealer. WARNING: Stored energy device. Improper release of springs can result in serious personal injury.

Springs should be removed by an authorized techni- cian.

• Models equipped with an engine radiator: WARNING: Stored energy device. To prevent serious bodily injury from hot coolant or steam blow-out, never

attempt to remove the radiator cap while the engine is

running. Stop the engine and wait until it is cool. Even then, use extreme care when removing the cap.

any necessary adjustments by tightening or loosen-

ing the adjustment nuts.

NOTE: The actual air gap between the rotor and arma- ture may vary even after performing the adjustment pro-

cedure. This is due to dimensional variations on compo- nent parts, and is an acceptable condition.

6. Check the mower blade stopping time. The mower blades and mower drive belt should come to a com-

plete stop within five seconds after the electric PTO switch is turned off.

, Perform the "Blade Brake Check" found in the MAIN-

TENANCE section. Mower blades and mower drive belt should come to a complete stop within five sec-

onds after electric PTO switch is turned off.

* The gross power rating for individual gas engine models is labeled in accordance with SAE (Society of Automotive Engineers) code J1940 (Small Engine Power & Torque Rating Procedure), and rating performance has been obtained and corrected in accordance with SAE J1995 (Revision 2002-05). Torque values are derived at 3060 RPM; horsepower values are derived at 3600 RPM. Actual gross engine power will be lower and is affected by, among other things, ambient operating conditions and engine-to-engine variability. Given both the wide array of products on

which engines are placed and the variety of environmental issues applicable to operating the equipment, the gas engine will not develop the rated gross power when used in a given piece of power equipment (actual "on-site" or net power). This difference is due to a variety of factors including, but not limited to, accessories (air cleaner, exhaust, charging, cooling, carburetor, fuel pump, etc.), application limitations, ambient operating conditions (temperature, humidity, altitude), and engine-to-engine variability. Due to manufacturing and capacity limitations, Briggs & Stratton may substitute an engine of higher rated power for this Series engine.
