serial numbers of your product ready. Figure 1 illustrates the location of the model and serial numbers on the product. 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 symbol, which means attention to the safety alert CAUTION, WARNING, or DANGER—“personal safety instruction.” Failure to comply with the instruction may result in personal injury or death.
• Check that operator’s presence controls, safety switches and shields are attached and functioning properly. Do not operate unless they are functioning properly. Maintenance and storage • Disengage drives, set parking brake, stop engine and disconnect spark plug wire. Wait for all movement to stop before adjusting, cleaning or repairing. Operation • Clean grass and debris from cutting unit, drives, mufflers, and engine to help prevent fires. Clean up oil or fuel spillage.
• Be aware of the mower discharge direction and do not point it at anyone. Do not operate the mower without either the entire grass catcher or the guard in place. • Do not mow on wet grass. Reduced traction could cause sliding. • Do not use a grass catcher on steep slopes. Heavy grass bags could cause loss of control of the machine. • Slow down before turning. Sharp turns on any terrain may cause loss of control. • Do not mow up and down slopes. • Turn off blades when not mowing.
Slope Chart Fold along appropriate line Example: Compare slope with folded edge. Align this edge with a vertical surface (Tree, Building, Fence post, pole, etc.

Gasoline and Oil Warning Gasoline is harmful or fatal if swallowed. Long-term exposure to vapors can cause serious injury and illness. 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. • Avoid prolonged breathing of vapors. • Keep face away from nozzle and gas tank or conditioner opening. • Keep gas away from eyes and skin.

Using Side Discharge or Mulch Grass Note: Lifting up on handle will assist driving the machine up a curb and not spin the drive wheels. This mower has a hinged grass deflector that disperses clippings to the side and down toward the turf. 1 Danger 2 Without the grass deflector, discharge cover, or complete grass catcher assembly mounted in place, you and others are exposed to blade contact and thrown debris. Contact with rotating mower blade(s) and thrown debris will cause injury or death.

Maintenance Note: Determine the left and right sides of the machine from the normal operating position. Important Refer to your engine operator’s manual for additional maintenance procedures.
Servicing the Cutting Blades Checking for Bent 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. 1. Rotate the blades until the ends face forward and backward (Fig. 25). Measure from a level surface to the cutting edge of the blades (Fig. 26). Note this dimension.
blade is not balanced, file some metal off the end of the sail area only (Fig. 28). Repeat this procedure until the blade is balanced. machine, use genuine TORO replacement blades. Replacement blades made by other manufacturers may result in non-conformance with safety standards. Hold the blade bolt with a wrench. Remove the nut, blade bolt, cone washer, blade, spacers and thin washer from the spindle (Fig. 27). 2 1 6 Figure 29 1. Blade 5 4 4 1 m–1855 2. Balancer Installing the Blades 3 1.
1. Lightly tap the element on a flat surface to remove dust and dirt (Fig. 32). 4. Carefully slide the foam element off the paper element (Fig. 30). 2. Inspect the element for tears, an oily film, and damage to the rubber seal. 1 Important Never clean the paper element with pressurized air or liquids, such as solvent, gas, or kerosene. Replace the paper element if it is damaged, defective, or cannot be cleaned thoroughly. 2 3 4 5 6 1 m–2595 Figure 30 1. Cover and nut 2. Wing nut 3.
USE THESE SAE VISCOSITY OILS Changing the Engine Oil 1. Start the engine and let it run five minutes. This warms the oil so it drains better. 10W–30 2. Park the machine so that the drain side is slightly lower than the opposite side to assure the oil drains completely. Then disengage the power take off (PTO), set the parking brake, and turn the engine off. 5W–20, 5W–30 –20 5F 0 –30 5C –20 20 –10 32 40 80 60 0 10 20 3. Place a pan below the oil drain. Remove the oil drain cap (Fig. 34).

Turn the oil filter clockwise until the rubber gasket contacts the filter adapter, then tighten the filter an additional 1/2 turn (Fig. 35). 1. Look at the center of the spark plug(s) (Fig. 37). If you see light brown or gray on the insulator, the engine is operating properly.
2. Tighten the spark plug(s) to 20 ft-lb (27 N.m). How to Grease 3. Push the wire(s) onto the spark plug(s) (Fig. 36). 1. Disengage the blade control (PTO) and set the parking brake. Checking the Tire Pressure 2. Clean the grease fittings with a rag. Make sure to scrape any paint off the front of the fitting(s). Service Interval/Specification 3. Connect a grease gun to the fitting. Pump grease into the fittings until grease begins to ooze out of the bearings.
4. Check the brake operation again; refer to Checking the Brake, page 30. Important With the parking brake released, the rear wheels must rotate freely when you push the mower. If brake action and free wheel rotation cannot be achieved contact your service dealer immediately. 1 m–4749 Figure 41 Servicing the Brakes 2 m–3773 Service Interval/Specification Figure 42 Before each use, check brakes for proper operation. 1.
5. Install the fuel line onto the fuel filter. Slide the hose clamp close to the filter to secure the fuel line. 1 2 3 m–3778 2 1 Figure 44 1. Hose clamp m–3778 2. Filter Figure 43 1.

Idler Pulley 10. Check the belt guide under the engine frame for proper adjustment (Fig. 46). The distance between the belt guide and mower belt should be 1-1/4 in. (32 mm) when mower belt is engaged. Adjust as necessary. The disengaged belt should not drag or fall off pulley when guides are properly adjusted.
Replacing the Grass Deflector 3. Adjust the nut at the end of the blade brake rod until there is 1/8–3/16 in. (3mm–5mm) between the nut and spacer (Fig. 50). Warning 4. Engage the blades. Ensure the blade brake pad no longer contacts the pulley edges. 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. Also, contact with the blade could occur.
