5

Safety

•

Before operating a machine with ROPS (roll over protection) be certain the seat belts are attached to prevent the seat from pivoting forward.

Slope Operation

Slopes and ramps are a major factor related to loss-of-control and tip-over accidents, which can result in severe injury or death. All slopes and ramps require extra caution. If you cannot back up the slope or if you feel uneasy on it, do not mow it.

DO

•

Mow up and down slopes greater than 5

°

, not across.

•

Mow downhill only on slopes above 10

°

, never mow uphill. If a steep slope must be ascended, back up the hill, and drive forward down the hill, keeping the machine in gear.

•

Remove obstacles such as rocks, tree limbs, etc.

from the mowing area. Watch for holes, ruts or bumps, as uneven terrain could overturn the machine. Tall grass can hide obstacles.

•

Use slow speed so that you will not have to stop while on the slope.

•

Follow the manufacturer’s recommendations for wheel weights or counterweights to improve stability.

•

Use extra care with grass catchers or other attachments. These can change the stability of the machine.

•

Keep all movement on slopes slow and gradual.

Do not make sudden changes in speed or direction.

•

Avoid starting or stopping on a slope. If tires lose traction, disengage the blades and proceed slowly straight down the slope.

•

When operating machine on slopes, banks or near drop offs, always have ROPS (roll over protection) installed.

•

When operating a machine with ROPS (roll over protection) always use seat belt.

•

Be certain that the seat belt can be released quickly if the machine is driven or rolls into ponds or water.

•

Check carefully for overhead clearances (i.e.

branches, doorways, electrical wires) before driving under any objects and do not contact them.

DO NOT

•

Do not operate machine on hillsides or slopes exceeding 15

°

.

•

Avoid turning on slopes. If you must turn, turn slowly and gradually downhill, if possible.

•

Do not mow near drop-offs, ditches, or embankments. The machine could suddenly turn over if a wheel goes over the edge of a cliff or ditch, or if an edge caves in.

•

Do not mow on wet grass. Reduced traction could cause sliding.

•

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

•

Do not use a grass catcher on steep slopes.

Heavy grass bags could cause loss of control or overturn the machine.

Service

•

Never store the machine or fuel container inside where there is an open flame, such as near a water heater or furnace.

•

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

•

Never tamper with safety devices. Check safety systems for proper operation before each use.

•

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

6

•

Check brake operation frequently. Adjust and service as required.

•

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.

•

Hydraulic fluid escaping under pressure can penetrate the skin and cause injury. Use cardboard or paper to find hydraulic leaks.

•

Never modify ROPS (roll over protection) frames or structures because they are specifically designed, sized, located and tested for injury reduction. If a rollover occurs, a modified ROPS will not provide adequate protection.

Gasoline and Oil

Recommended Gasoline

Use UNLEADED Regular Gasoline suitable for automotive use (85 pump octane minimum). Leaded regular gasoline may be used if unleaded regular is not available.

IMPORTANT: Never use methanol, gasoline containing methanol, or gasohol containing more than 10% ethanol because the fuel system could be damaged. Do not mix oil with gasoline.


•

In certain conditions gasoline is extremely flammable and highly explosive.

WHAT CAN HAPPEN

•

A fire or explosion from gasoline can burn you, others, and cause property damage.


•

Fill the fuel tank outdoors, in an open area, when the engine is cold. Wipe up any gasoline that spills.

•

Do not fill the fuel tank completely full.

Add gasoline to the fuel tank until the level is 1/4” to 1/2” (6 mm to 13 mm) below the bottom of the filler neck. This empty space in the tank allows gasoline to expand.

•

Never smoke when handling gasoline, and stay away from an open flame or where gasoline fumes may be ignited by a spark.

•

Store gasoline in an approved container and keep it out of the reach of children.

Never buy more than a 30-day supply of gasoline.


•


WHAT CAN HAPPEN

•



•

Always place gasoline containers on the ground away from your vehicle before filling.

•

Do not fill gasoline containers inside a vehicle or on a truck or trailer bed because interior carpets or plastic truck bed liners may insulate the container and slow the loss of any static charge.

•

When practical, remove gas–powered equipment from the truck or trailer and refuel the equipment with its wheels on the ground.

•

If this is not possible, then refuel such equipment on a truck or trailer from a portable container, rather than from a gasoline dispenser nozzle.

•

If a gasoline dispenser nozzle must be used, keep the nozzle in contact with the rim of the fuel tank or container opening at all times until fueling is complete.

15

Gasoline and Oil


•

Gasoline is harmful or fatal if swallowed.

Long–term eposure to vapors has caused cancer to laboratory animals.

WHAT CAN HAPPEN

•

Failure to use caution may result in serious injury or illness


•

Avoid prolonged breathing of vapors.

•

Keep face away from nozzle and gas tank or conditioner opening.

•

Keep gas away from eyes and skin.

Filling the Fuel Tank

1.

Shut the engine off and set the parking brake.

2.

Clean around each fuel tank cap and remove the cap. Add unleaded regular gasoline to both fuel tanks, until the level is 1/4 to 1/2 inch (6 mm to

13 mm) below the bottom of the filler neck. This space in the tank allows gasoline to expand. Do not fill the fuel tanks completely full.

3.

Install fuel tank caps securely. Wipe up any gasoline that may have spilled.

Using Stabilizer/Conditioner

Use a fuel stabilizer/conditioner in the machine to provide the following benefits:

•

Keeps gasoline fresh during storage of 90 days or less. For longer storage it is recommended that the fuel tank be drained.

•

Cleans the engine while it runs

•

Eliminates gum-like varnish buildup in the fuel system, which causes hard starting

IMPORTANT: Do not use fuel additives containing methanol or ethanol.

Add the correct amount of gas stabilizer/conditioner to the gas.

Note:

A fuel stabilizer/conditioner is most effective when mixed with fresh gasoline. To minimize the chance of varnish deposits in the fuel system, use fuel stabilizer at all times.

Check Engine Oil Level

Before you start the engine and use the machine, check the oil level in the engine crankcase; refer to

Checking Oil Level, page 41.

Operation

Transporting Machines

Use a heavy–duty trailer or truck to transport the machine. Ensure that the trailer or truck has all necessary lighting and marking as required by law.

Please carefully read all the safety instructions on pages 3–13. Knowing this information could help you, your family, pets or bystanders avoid injury.

To transport the machine:

•

Lock brake and block wheels.

•

Securely fasten the machine to the trailer or truck with straps, chains, cable, or ropes.

•

Secure a trailer with a safety chains to towing vehicle.


•

This unit does not have proper turn signals, lights, reflective markings, or a slow moving vehicle emblem. These items are required to drive on a public street or roadway.

WHAT CAN HAPPEN

•

Driving on a street or roadway without such equipment is dangerous and can lead to accidents causing personal injury.

•

Driving on a street or roadway without such equipment may also be a violation of

State laws and the operator may be subject to traffic tickets and/or fines.


•

Do not drive machine on a public street or roadway.

Loading Machines

Use extreme caution when loading units on trailers or trucks. One full width ramp that is wide enough to extend beyond the rear tires is recommended instead of individual ramps for each side of the unit. The lower rear section of the tractor frame extends back between the rear wheels and serves as a stop for tipping backward. Having a full width ramp provides a surface for the frame members to contact if the unit starts to tip backward. If it is not possible to use one full width ramp, use enough individual ramps to simulate a full width continuous ramp.

Ramp should be long enough so that the angles between the ramp and the ground and the ramp and the trailer or truck do not exceed 15 degrees. A steeper angle may cause mower deck components to get caught as the unit moves from ramp to trailer or truck. Steeper angles may also cause the unit to tip backward. If loading on or near a slope, position the trailer or truck so it is on the down side of the slope and the ramp extends up the slope. This will minimize the ramp angle. The trailer or truck should be as level as possible.

IMPORTANT: DO NOT attempt to turn the unit while on the ramp; you may lose control and drive off the side.

Avoid sudden acceleration when driving up a ramp and sudden deceleration when backing down a ramp.

Both maneuvers can cause the unit to tip backward.

32


•

Loading a unit on a trailer or truck increases the possibility of backward tip–over.

WHAT CAN HAPPEN

•

Backward tip–over of the unit could cause serious injury or death.


•

Use extreme caution when operating a unit on a ramp.

•

Use only a single, full width ramp; DO

NOT use individual ramps for each side of the unit.

•

If individual ramps must be used, use enough ramps to create an unbroken ramp surface wider than the unit.

•

DO NOT exceed a 15 degree angle between ramp and ground or between ramp and trailer or truck.

•

Avoid sudden acceleration while driving unit up a ramp to avoid tipping backward.

•

Avoid sudden deceleration while backing unit down a ramp to avoid tipping backward.

Operation

Tips for Mowing Grass

Fast Throttle Setting

For best mowing and maximum air circulation, operate the engine at “FAST.” Air is required to thoroughly cut grass clippings, so do not set the height-of-cut so low as to totally surround the mower by uncut grass. Always try to have one side of the mower free from uncut grass, which allows air to be drawn into the mower.

Cutting a Lawn for the First Time

Cut grass slightly longer than normal to ensure the cutting height of the mower does not scalp any uneven ground. However, the cutting height used in the past is generally the best one to use. When cutting grass longer than six inches tall, you may want to cut the lawn twice to ensure an acceptable quality of cut.

Cut 1/3 of the Grass Blade

It is best to cut only about 1/3 of the grass blade.

Cutting more than that is not recommended unless grass is sparse, or it is late fall when grass grows more slowly.

Mowing Direction

Alternate mowing direction to keep the grass standing straight. This also helps disperse clippings which enhances decomposition and fertilization.

Mow at Correct Intervals

Normally, mow every four days. But remember, grass grows at different rates at different times. So to maintain the same cutting height, which is a good practice, mow more often in early spring. As the grass growth rate slows in mid summer, mow less frequently. If you cannot mow for an extended period, first mow at a high cutting height; then mow again two days later at a lower height setting.

Cutting Speed

To improve cut quality, use a slower ground speed in certain conditions.

Avoid Cutting Too Low

If the cutting width of the mower is wider than the mower you previously used, raise the cutting height to ensure that uneven turf is not cut too short.

Long Grass

If the grass is ever allowed to grow slightly longer than normal, or if it contains a high degree of moisture, raise the cutting height higher than usual and cut the grass at this setting. Then cut the grass again using the lower, normal setting.

When Stopping

If the machine’s forward motion must be stopped while mowing, a clump of grass clippings may drop onto your lawn. To avoid this, move onto a previously cut area with the blades “ENGAGED”.

Keep the Underside of the Mower Clean

Clean clippings and dirt from the underside of the mower after each use. If grass and dirt build up inside the mower, cutting quality will eventually become unsatisfactory.

Blade Maintenance

Maintain a sharp blade throughout the cutting season because a sharp blade cuts cleanly without tearing or shredding the grass blades. Tearing and shredding turns grass brown at the edges, which slows growth and increases the chance of disease. Check the cutter blades daily for sharpness, and for any wear or damage. File down any nicks and sharpen the blades as necessary. If a blade is damaged or worn, replace it immediately with a genuine TORO replacement blade.

Maintenance


•

If you leave the key in the ignition switch, someone could start the engine.

WHAT CAN HAPPEN

•

Accidental starting of the engine could seriously injure you or other bystanders.


•

Remove the key from the ignition switch and pull the wire(s) off the spark plug(s) before you do any maintenance. Also push the wire(s) aside so it does not accidentally contact the spark plug(s).

Cutting Blades

Maintain sharp blades throughout the cutting season because sharp blades cuts cleanly without tearing or shredding the grass blades. Tearing and shredding turns grass brown at the edges, which slows growth and increases the chance of disease.

Check the cutter blades daily for sharpness, and for any wear or damage. File down any nicks and sharpen the blades as necessary. If a blade is damaged or worn, replace it immediately with a genuine TORO replacement blade. For convenient sharpening and replacement, you may want to keep extra blades on hand.

Before Inspecting or Servicing the

Blades

Park the machine on a level surface, disengage the blade control (PTO) and set the parking brake. Turn the ignition key to “OFF” to stop the engine. Remove the key and disconnect the spark plug wire(s) from the spark plug(s).


•

A blade that is worn or damaged could break apart and pieces could be thrown at bystanders or at you as you use the mower.

WHAT CAN HAPPEN

•

Pieces of blade that may be thrown could seriously injure or kill you or bystanders.


•

Periodically inspect the blade for wear and damage. Immediately install a new blade if it is worn or damaged.

36

Inspecting the Blades

1.

Inspect the cutting edges (Fig 15). If the edges are not sharp or have nicks, remove and sharpen the blades. Refer to Sharpening the Blades on page 38.

Maintenance

Sharpening the Blades


•

A blade that is bent or damaged could break apart and pieces could be thrown at bystanders or at you as you use the mower.

WHAT CAN HAPPEN

•

Pieces of blade that may be thrown could seriously injure or kill you or bystanders.


•

Always replace bent or damaged blade with a new blade.

•

Never file or create sharp notches in the edges or surfaces of blade.

Removing the Blades

Blades must be replaced if a solid object is hit, if the blade is out of balance or is bent. To ensure optimum performance and continued safety conformance of the machine, use genuine TORO replacement blades.

Replacement blades made by other manufacturers may result in non-conformance with safety standards.


•

When sharpening blade, pieces of blade could be accidentally thrown.

WHAT CAN HAPPEN

•

Thrown objects can cause serious eye injury.


•

Wear proper eye protection when sharpening blade.

1.

Use a file to sharpen the cutting edge at both ends of the blade (Fig. 18). Maintain the original angle. The blade retains its balance if the same amount of material is removed from both cutting edges.

•

Blade is sharp.

WHAT CAN HAPPEN

•

Contact with sharp blade can cause serious personal injury.


•

Wear gloves or wrap sharp edges of the blade with a rag.

1.

Hold the blade end using a rag or thickly-padded glove. Remove the blade bolt, spring disk and blade from the spindle shaft (Fig. 20).

Waste Disposal

Engine oil, hydraulic oil and engine coolant are pollutants to the environment. Dispose of these according to your state and local regulations.

Mercury Tilt Switch

The tilt switch on this unit is located under the seat.

Tilt seat up to gain access.

The tilt switch on this unit contains mercury, a hazardous material. Mercury that is outside a sealed container vaporizes at room temperature. The vapors are harmful. Mercury can be absorbed through the skin. Do not attempt to open or repair this switch.

A very small amount of mercury is contained in a hermetically sealed body. The steel switch is then potted in a hard epoxy in a plastic case. It is unlikely that the mercury will ever escape from the enclosure.

These high performance and reliable inexpensive switches are recyclable.

Mercury is an important and beneficial compound but requires special care in handling and disposal. When used and managed properly, mercury is not a threat to people or the environment. This information is presented to users so that they are aware that these switches contain mercury and will apply sound disposal practices when these devices reach their normal end of life or are damaged.

Mercury Tilt Switch Disposal

Several states have passed laws concerning the disposal of devices containing mercury. In all the remaining states it is advisable to follow similar procedures. The laws state that these sealed devices contain mercury and should not be placed in the garbage until the mercury is removed and reused, recycled or otherwise managed to insure that it does not become part of solid waste or waters.

Management and disposal practices must be within relevant federal, state or local laws.

Return the switch to your Toro dealer if it is faulty and is being replaced or if the unit containing the switch is no longer operating and is being scrapped. If the switch is damaged or broken open use extreme caution in handling. Call your local waste management authority or Toro Customer Service for instructions.


•

The mercury contained in the tilt switch is poisonous.

WHAT CAN HAPPEN

•

Exposure to mercury can cause severe illness.


•

Never attempt to open or repair the tilt switch.

•

Avoid contact with the mercury.
