Gasoline Warning signals a hazard that may cause serious injury or death if you do not follow the recommended precautions. • WARNING–Gasoline is highly flammable. Take the following precautions. Caution signals a hazard that may cause minor or moderate injury if you do not follow the recommended precautions. – Store fuel in containers specifically designed for this purpose. This manual uses two other words to highlight information.
• Stay alert for holes in the terrain and other hidden hazards. – if lawn mower starts to vibrate abnormally (check immediately). • Never direct discharge of material towards bystanders. Use care when using sulkies, and • Avoid operating the equipment in wet grass, where feasible. – use only approved drawbar hitch points. • Do not put hands or feet near or under rotating parts. Keep clear of the discharge opening at all times. – do not turn sharply; use care when reversing.
• To ensure the best performance and safety, purchase only genuine Toro replacement parts and accessories. Do not use “will fit” parts and accessories; they may cause a safety hazard. Sound Pressure Level Check with manufacturer of deck. Sound Power Level Check with manufacturer of deck. Vibration Level Check with manufacturer of deck.

Gasoline and Oil Recommended Gasoline Warning Use UNLEADED Regular Gasoline suitable for automotive use (85 pump octane minimum). Leaded regular gasoline may be used if unleaded regular is not available. Gasoline is harmful or fatal if swallowed. Long–term exposure to vapors can cause serious injury and illness. 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.

Squeeze the blade control bail against upper control bar. The blades should not rotate. 2. Release the parking brake: refer to Releasing the Parking Brake, page 16. 3. Then continue holding the blade control bail and pull up on the blade control switch and release. The clutch should engage and the mower blades begin rotating. 3.
Transporting Machines 1 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. Knowing this information could help you, your family, pets or bystanders avoid injury. 2 To transport the machine: • Lock brake and block wheels. • Securely fasten the machine to the trailer or truck with straps, chains, cable, or ropes.
Maintenance Note: Determine the left and right sides of the machine from the normal operating position.

Engine Oil Service 1 2 Service Interval/Specification Change oil: 3 • After the first 5 operating hours. • After every 50 operating hours. Note: Change oil more frequently when operating conditions are extremely dusty or sandy. Oil Type: Detergent oil (API service SF, SE/CC, CD or SE) Figure 22 Crankcase Capacity: with filter, 54 oz. (1.6 l) with out filter, 47 oz. (1.4 l) 1. Oil dipstick 2. Metal end 3. Filler tube Viscosity: See table below USE THESE SAE VISCOSITY OILS Changing/Draining Oil 1.
Spark Plug Service 5. Slowly pour approximately 80% of the specified oil, page 22, into the filler tube (Fig. 22). Now check the oil level; refer to Checking Oil Level, page 22. Slowly add additional oil to bring to “FULL” mark on dipstick. Service Interval/Specification Service Interval/Specification Check the spark plug(s) after every 100 operating hours. Make sure the air gap between the center and side electrodes is correct before installing the spark plug.
Note: Make sure the rear wheel grease caps are removed before lubricating rear wheels. 2. Check the gap between the center and side electrodes (Fig. 26). Bend the side electrode (Fig. 26) if the gap is not correct. 2 3 1 0.025 in. (0.65 mm) m–2147 Figure 27 Figure 26 1. Center electrode insulator 2. Side electrode 3. Air gap (not to scale) 2.

and linkage. This will help insure adequate cooling and correct engine speed and will reduce the possibility of overheating and mechanical damage to the engine. Checking Tire Pressure Service Interval/Specification Maintain the air pressure in the front and rear tires as specified. Check the pressure at the valve stem after every 40 operating hours or monthly, whichever occurs first (Fig. 29). Check the tires when they are cold to get the most accurate pressure reading.
3. To adjust the brake remove the cotter pin and washer from the brake lever (Fig. 31). 2. Close fuel shut–off valve at fuel tank (Fig. 32). 3. Squeeze the ends of the hose clamp together and slide it up the fuel line away from valve (Fig. 32). 4. Rotate the trunnion so it smoothly slides into brake lever hole “F” (Fig. 31). Tighten wing nut. 4. Pull the fuel line off the valve (Fig. 32). Open fuel shut-off valve and allow gasoline to drain into a gas can or drain pan. 5.
Adjusting the Electric Clutch 5. Install a new filter and move the hose clamps close to the filter. The clutch is adjustable to ensure proper engagement and proper braking. Check adjustment after every 100 hours of operation. 6. Open fuel shut-off valve at fuel tank (Fig. 32). 7. Check for fuel leaks and repair if needed (Fig. 32). 3 1. To adjust clutch, tighten or loosen lock nuts on flange studs (Fig. 35). 1 2. Check adjustment by inserting feeler gauge thru slots next to studs (Fig. 35). 3.
