• If gasoline is spilled, do not attempt to start the engine but move the machine away from the are of spillage and avoid creating any source of ignition until gasoline vapors have dissipated. WARNING signals a hazard that may cause serious injury or death if the recommended precautions are not followed. CAUTION signals a hazard that may cause minor or moderate injury if the recommended precautions are not followed. • Replace all fuel tanks and container caps securely.

Assembly 4 3 Handle 1. Mount handle to outside of mower housing, using bottom hole, with (2) 5/16–18 x 1–1/4” (8 mm x 31 mm) capscrews, washers, and thin nylon insert locknuts (Fig. 2). 2 2. Secure handle latches to handle with (2) 5/16–18 x 1–1/2” (8 mm x 38 mm) capscrews, washers and nylon insert locknuts (Fig. 2). Note: Handle height is adjustable for operator comfort. Stand behind mower handle to gauge height.
Discharge Tunnel Plug Before Starting 1. Open the discharge door by pulling forward on the handle and moving it rearwards (Fig. 5). Hold the discharge door handle to prevent the spring–loaded door from closing while inserting the plug. Fill Crankcase With Oil Fill crankcase with SAE 30 or 10W30 oil until oil level reaches FULL mark on dipstick as shown in (Fig. 7). The maximum crankcase capacity is 26 ounces (0.77 liters) of oil with the oil filter installed and 22 ounces (0.
Fill Fuel Tank With Gasoline This engine is certified to operate on unleaded gasoline. Toro strongly recommends the use of fresh, clean, UNLEADED regular grade gasoline with an octane rating of 85 or higher in Toro gasoline powered products. Unleaded gasoline burns cleaner, extends engine life, and promotes good starting by reducing the build-up of combustion chamber deposits. In countries other than U.S.A., leaded gasoline may be used if it is commercially available and unleaded is unavailable.
Recycling Tips General Tips Follow these instructions whether cutting grass or leaves for the best cutting results and lawn appearance: • Maintain a sharp blade throughout the cutting season. Periodically file down nicks on blade. • Only mow dry grass or leaves. Wet grass and leaves tend to clump on yard and may cause mower to plug or engine to stall. They also may be slippery to walk on and could cause you to slip and fall.
• If there are more than five inches of leaves on lawn, set the front wheels one or two notches higher than the rear wheels. This makes it easier to feed leaves under mower deck. Starting Note: The engine requires a warm-up period of one minute to several minutes, depending on the temperature. • Walk at a slower mowing speed if leaves are not being cut up finely enough to be hidden down in the grass. 1. Push spark plug wire onto spark plug (Fig. 11). (FAST) position. 2.
2. Since the plug is slightly wider than the discharge tunnel opening, you must rotate the plug clockwise slightly while inserting it (Fig. 5). Make sure the arrow on the plug decal is pointing upward. DANGER POTENTIAL HAZARD • Grass clippings and other objects can be thrown from an open discharge tunnel. 3. Push the plug all the way in until the spring clip on the bottom of the plug clicks into place, locking the plug securely into the discharge tunnel (Fig. 6).
DANGER DANGER POTENTIAL HAZARD • Thrown objects may result if discharge door does not close completely. POTENTIAL HAZARD • Adjusting height-of-cut levers could bring hands into contact with moving blade. WHAT CAN HAPPEN • Thrown objects can cause serious personal injury or death. WHAT CAN HAPPEN • Contact with blade could cause serious personal injury.
2. Clean around spark plug and remove plug from cylinder head. 1 IMPORTANT: Replace a cracked, fouled, or dirty spark plug. Do not sand blast, scrape, or clean electrodes because engine damage could result from grit entering cylinder. 2 ÏÏÏÏ ÏÏÏÏ ÏÏÏÏ 3. Set air gap at 0.020” (0.5 mm) (Fig. 16). Install correctly gapped spark plug and gasket seal. Tighten plug firmly to 14 ft–lb (19 N m). 4 0.81 mm (0.032") 3 m-110 m–3664 Figure 16 Figure 15 1. Knob 2. Cover 3. Foam pre–cleaner 4.
4. Tip mower on its left side, allowing oil to drain into drain pan (Fig. 17). 6. Install the new filter and hand tighten it 2/3 turn only. 7. Check the filter for any oil leaks. 8. Properly discard the oily rag. 1 Adjusting Throttle Throttle control adjustment may be required if engine does not start. Whenever a new throttle control cable is installed, throttle must be adjusted. 1. Stop engine and wait for all moving parts to stop. Pull wire off spark plug (Fig. 11). 2.
Cleaning Cooling System After every 100 operating hours, clean dirt and chaff from cylinder, cylinder head fins, and from around carburetor and linkage with a brush or air hose. Also remove debris from air intake slots on recoil housing. This will ensure proper cooling and optimum engine performance.
3. CHECK ADJUSTMENT—Slowly pull mower backward while control bar is gradually moved toward handle. Adjustment is correct when rear wheels stop turning and control bar is about 1 inch from handle (Fig. 23). CAUTION POTENTIAL HAZARD • Someone could accidentally start the engine. WHAT CAN HAPPEN • Accidental starting of engine could cause serious injury to operator or bystanders.
DANGER WARNING POTENTIAL HAZARD • A worn or damaged blade could break and a piece of blade could be thrown into operator’s or bystander’s area. POTENTIAL HAZARD • Operating mower without accelerator in place could cause blade to flex, bend or break. WHAT CAN HAPPEN • A broken blade could cause serious injury or death to operator or bystanders. WHAT CAN HAPPEN • A thrown piece of blade could cause serious personal injury or death to operator or bystanders.

Brake cable Adjusting Blade Brake Cable Cleaning Mower Whenever a new blade brake cable assembly is installed, an adjustment is required. Plug 1. Stop engine and pull wire off spark plug (Fig. 11). After each use, remove plug from discharge tunnel and clean off all debris. 2. CHECK ADJUSTMENT (Fig. 29)—Move control bar toward handle until slack in wire is removed.
Underside of Mower Housing 8. If underside of mower deck has excessive grass build-up or packing, reconnect the hose to the washout fitting, turn the water on high and run the mower for two minutes. Stop the mower and turn off the water. Let the mower soak for 30 minutes. Then turn the water on high again and run the mower for another two minutes. Keep underside of mower housing clean. Be especially careful to keep kickers free of debris (Fig. 31).
Removal 1 1. Stop engine and wait for all moving parts to stop. Pull wire off spark plug (Fig. 11). 2. Remove capscrew, wheel spacer, and locknut mounting wheel to pivot arm. 2 3 3. Separate wheel halves from tire by removing (4) capscrews and locknuts. 2 m–3844 Figure 34 Note: If bearings are to be removed from bearing/hub assembly, remove by pressing on bearing spacer. 1.

4. Clean mower housing: refer to Cleaning Mower, page 20. 5. Clean dirt and chaff from cylinder, cylinder head fins, and blower housing. Also remove grass clippings, dirt, and grime from external parts of the engine, shrouding, and top of mower housing. 6. Check condition of blade: refer to Inspecting/Removing/Sharpening Blade, page 18. 7. Tighten all nuts, bolts, and screws. 8. Clean air cleaner: refer to Servicing Air Cleaner, page 14. 9.
