Operation

Adding Fuel

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

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

• Never fill the fuel tank inside an enclosed trailer.

• Do not fill the fuel tank completely full. Add gasoline to the fuel tank until the level is 1/4 to 1/2 inch (6 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.

• Do not operate without entire exhaust system in place and in proper working condition.

In certain conditions during fueling, static electricity can be released causing a spark which can ignite the gasoline vapors. A fire or explosion from gasoline can burn you and others and can damage property.

• 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.

Gasoline is harmful or fatal if swallowed.

Long-term exposure to vapors can cause serious injury and illness.

• Avoid prolonged breathing of vapors.

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

• Keep gas away from eyes and skin.

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

13

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.

Filling the Fuel Tank

1. Shut the engine off and set the parking brake.

2. Clean around fuel tank cap and remove the cap.

Add unleaded regular gasoline to fuel tank, until the level is 1/4 to 1/2 inch (6 to 13 mm) below the bottom of the filler neck. This space in the tank allows gasoline to expand. Do not fill the fuel tank completely full.

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

Think Safety First

Carefully read all the safety instructions and decals in the safety section. Knowing this information could help you or any bystanders avoid injury.

The use of protective equipment for eyes, hearing, feet and head is recommended.

Important: The blade brake needs to be adjusted when the belt tension or the brake linkage is adjusted.

Important: The belt must be tight enough to not slip during heavy loads while cutting grass. Over tensioning the belt will reduce the bearing life of the belt and the spindle.



3. Loosen the locknut on the turnbuckle (Figure 36).

4. Rotate the turnbuckle toward the rear of the mower to increase the tension on the belt. Rotate the turnbuckle toward the front of the mower to

decrease the tension on the belt (Figure 36).

34

Note: The eyebolt threads on both ends of the turnbuckle should be engaged a minimum of

5/16 inch (8 mm).

Maintenance

Servicing the Cutting Blades

To ensure a superior quality of cut, keep the blades sharp. For convenient sharpening and replacement, you may want to keep extra blades on hand.

A worn or damaged blade can break, and a piece of the blade could be thrown into the operator’s or bystander’s area, resulting in serious personal injury or death.

• Inspect the blade periodically for wear or damage.

• Replace a worn or damaged blade.

Before Inspecting or Servicing the

Blades

Park the machine on a level surface, disengage the blade control bail and set the parking brake. Turn the ignition key to off. Remove the key and disconnect the spark plug wire(s) from the spark plug(s).

Inspecting the Blades


Inspect the blades every 8 hours.

1. Inspect the cutting edges (Figure 38). If the edges

are not sharp or have nicks, remove and sharpen the blades. Refer to Sharpening the Blades.

3.

Wear/slot Forming

2. Inspect the blades, especially the curved area

(Figure 38). If you notice any damage, wear, or a slot forming in this area (item 3 in Figure 38),

immediately install a new blade.

Checking for Bent Blades

1. Rotate the blades until the ends face forward and

backward (Figure 39).

Figure 39

1.

Measure from cutting edge to a level surface

2. Measure from a level surface to the cutting edge,

position A, of the blades (Figure 40). Note this

dimension.

3. Rotate the opposite ends of the blades forward.

4. Measure from a level surface to the cutting edge of

the blades at the same position as in step 1. The

difference between the dimensions obtained in steps

1 and 2 must not exceed 1/8 inch (3 mm). If this

dimension exceeds 1/8 inch (3 mm), the blade is bent and must be replaced. Refer to Removing the

Blades and Installing the Blades.

A blade that is bent or damaged could break apart and 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

Replace the blades if you hit a solid object or if the blades are out of balance or 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.

1. Hold the blade bolt with a wrench.

2. Remove the nut, blade bolt, curved washer, blade,

spacers, and thin washer from the spindle (Figure 41).

Sharpening the Blades

1. Use a file to sharpen the cutting edge at both ends

of the blade (Figure 42). Maintain the original angle.

The blade retains its balance if the same amount of material is removed from both cutting edges.

36

Figure 42

1.

Sharpen at original angle

2. Check the balance of the blade by putting it on a

blade balancer (Figure 43). If the blade stays in a

horizontal position, the blade is balanced and can be used. If the blade is not balanced, file some metal off

the end of the sail area only (Figure 43). Repeat this

procedure until the blade is balanced.

Installing the Blades

1. Install the curved washer and then the blade onto the bolt. Select the proper number of spacer(s) for the height-of- cut, and slide the bolt into the spindle

(Figure 41).

Important: The curved part of the blade must point upward toward the inside of the mower to ensure proper cutting.

2. Install the remaining spacer(s) and secure them with

a thin washer and a nut (Fig. Figure 41).

3. Torque the blade bolt to 75-80 ft-lb (101-108 N•m).

Adjusting the Blade Brake

1. Disengage the PTO, turn the ignition key to off, and remove the key.

2. Wait for all moving parts to stop before leaving the operating position and then set the parking brakes.

3. If necessary, adjust the spring mounting bolts so that the blade brake pad rubs against both sides of the

pulley groove (Figure 44).

4. Adjust the nut at the end of the blade brake rod until there is 1/8-3/16 inch (3 mm -5 mm) between the

nut and spacer (Figure 44).

5. Engage the blades. Ensure the blade brake pad no longer contacts the pulley groove.

Replacing the Grass Deflector

An uncovered discharge opening could allow the lawn mower to throw objects in the operator’s or bystander’s direction and result in serious injury or death. Also, contact with the blade could occur.

Never operate the lawn mower with the grass deflector removed unless you install a cover plate, a mulch plate, or a grass chute and catcher.

1. Remove the locknut, bolt, spring and spacer holding

the deflector to the pivot brackets (Figure 45).

Remove damaged or worn grass deflector.
