Safety Training 1. Read the instructions carefully. Be familiar with the controls and the proper use of the equipment. 2. Never allow children or people unfamiliar with these instructions to use the lawnmower. Local regulations may restrict the age of the operator. 3. 4. Never mow while people, especially children, or pets are nearby. 2. 3. • Replace all fuel tanks and container caps securely. Replace faulty silencers. 5.
Safety 10. Stop the blade(s) if the lawnmower has to be tilted for transportation when crossing surfaces other than grass, and when transporting the lawnmower to and from the area to be mowed. 11. Never operate the lawnmower with defective guards or shields, or without safety devices for example deflectors and/or grass catchers in place. 12. Do not change the engine governor settings or overspeed the engine. 13. Disengage all blade and drive clutches before starting the engine. 14.

Assembly Grass Bag Ramp Discharge Tunnel Plug 1. 1. Make sure engine is off. 2. Open discharge door and insert plug into discharge tunnel opening (Fig. 6). Since the plug is slightly wider than the discharge tunnel opening, you must rotate the plug clockwise slightly while inserting it. Snap three (3) tabs on grass bag ramp onto grass bag frame (Fig. 4 & 5). 1 2 3 1 1713 Figure 4 1. Grass bag ramp 2. Tab 1339 Figure 6 3. Grass bag frame 1. Plug 3.
Before Starting Fill Crankcase With Oil MARK BECAUSE ENGINE COULD BE DAMAGED WHEN STARTED. POUR OIL SLOWLY. Initially, crankcase must be filled with 0.6 L (20 ounces) of SAE 30 oil. Use any high quality detergent oil having the American Petroleum Institute (API) “service classification”—SF, SG or SH. Note: Before each use, assure oil level is between ADD and FULL marks (Fig. 7). Add oil if level is low. 4 4. Check oil level each time mower is used or after every 5 hours of mower operation.
Before Starting 1. Clean around fuel tank cap and remove cap from tank (Fig. 7). Do not fill tank full. Using unleaded gasoline, fill fuel tank to within 6 to 13 mm (1/4” to 1/2”) from top of tank, not into filler neck. 2. Install fuel tank cap and wipe up any spilled gasoline. Toro also recommends that Toro Stabilizer/Conditioner be used regularly in all Toro gasoline powered products during operation and storage seasons.
Operation Controls 2 Self-propelled control bar (self-propelled model), throttle, blade control bar and recoil starter are on the handle (Fig. 8 and 9). 3 4 1 1 3 2 2339 Self-propelled model Figure 9 1.

Push spark plug wire onto spark plug (Fig. 10). 2. Push primer three (3) times (Fig. 10).
Operation Note: 3. Do not use primer to restart a warm engine after a short shutdown. However, cool weather may require priming to be repeated. Move throttle forward to To Restart Engine 1. Move throttle lever to (FAST) position and repeat steps 3 and 4 in STARTING ENGINE procedure. 2. If engine does not start after two attempts, repeat steps 2–4 in STARTING ENGINE procedure. (FAST) position. Hand Push model • Hold blade control bar against handle.
Operation 1 795 1339 Figure 12 Figure 13 1. Plug Removing 1. Stop engine and wait for all moving parts to stop. For protection, always keep hands and feet away from mower housing while engine is running. Raise discharge door. While holding discharge door up, grasp handle on grass bag and lift bag off mower. Allow discharge door to close. Note: When removing the grass bag, the bag ramp scoops out any clippings that may be plugging the discharge opening.
Operation POTENTIAL HAZARD • Wet grass or leaves can cause you to slip and contact blade. 1 WHAT CAN HAPPEN • Blade contact can seriously injure you. HOW TO AVOID THE HAZARD • Mow only in dry conditions. 2 4 3 Set engine speed to fastest position. Maximum horsepower provides best cutting results. • Clean clippings or leaves from underside of mower deck after each mowing. • Keep engine in good running condition. Cutting and recutting requires more horsepower. • Clean air filter more frequently.
Operation • Sharpen the blade. • Walk at a slower pace while mowing. • Raise the height-of-cut setting on your mower. • Cut grass more frequently. • Overlap cutting swaths instead of cutting a full swath with each pass. • Mow across the marginal areas a second time. Cutting Leaves • When cutting is complete, always be sure that 50% of the lawn shows through the cut leaf cover. This may require one or more passes over the leaves.
Maintenance POTENTIAL HAZARD • If you leave the wire on the spark plug, someone could start the engine. WHAT CAN HAPPEN • Accidental starting of engine could seriously injure you or other bystanders. HOW TO AVOID THE HAZARD • Pull wire off spark plug before you do any maintenance. Also push wire aside so it does not accidentally contact spark plug. Servicing Air Cleaner IMPORTANT: Do not operate engine without air cleaner filter otherwise extreme engine wear and damage will likely result.
Maintenance Changing Crankcase Oil Spark Plug Change oil after the first 2 operating hours and after every 25 hours thereafter. Since warm oil drains better and carries more contaminants than cold, run engine for several minutes or so before draining oil. Use a Champion RJ19LM spark plug or equivalent. Correct air gap is 0.76 mm (0.030”). Remove plug after every 25 operating hours and check its condition. 1. Stop engine and pull wire off spark plug (Fig. 15). 1.
Maintenance Adjusting Throttle 4. Move throttle control to Throttle control adjustment may be required if engine does not start or stop. Whenever a new throttle control cable is installed, throttle must be adjusted. 5. Move throttle cable until throttle lever contacts stop (Fig. 20). 6. Tighten cable clamp screw to lock adjustment in place. 7. Reinstall engine cover with (2) screws. Torque screws to 8-10 in.-lbs. (.9-1.1 N m) 1. 2. Stop engine and pull wire off spark plug (Fig. 15).
Maintenance 2 3 1 1 2341 2341 Self-propelled model shown Figure 22 1. Cable conduit 2. Cable bracket 3. 1. Adjustment knob 3. Nut ADJUST CABLE CONDUIT–Loosen the nut on the cable bracket. Insert 1.5mm-4.6mm ( / ”– / ”) object between the brake control bar and handle. Pull down on the cable conduit until all slack is removed from the wire. Then tighten the nut.
Maintenance 3 Inspecting/Removing/ Sharpening Blade A straight, sharp blade provides maximum cutting performance. Regularly inspect and sharpen blade. POTENTIAL HAZARD • Blade is sharp. WHAT CAN HAPPEN • Contact with sharp blade can cause serious personal injury. HOW TO AVOID THE HAZARD • Wear gloves or wrap sharp edges of the blade with a rag. 1. Stop engine and pull wire off spark plug (Fig. 15). 2. Drain gasoline from fuel tank. See Drain Gasoline section. 1 2 1973 Figure 24 1. Blade 2.
Maintenance Note: For best performance, install new blade before cutting season begins. During the year, file down small nicks to maintain the cutting edge. 1 153 Figure 26 1. Sharpen at this angle only POTENTIAL HAZARD • A worn or damaged blade could break and a piece of blade could be thrown into operator’s or bystander’s area. WHAT CAN HAPPEN • A thrown piece of blade could cause serious personal injury or death to operator or bystanders. 7.
Maintenance 1. Apply one or two drops of light oil on inside and outside of all wheel bolts. Spin wheels to distribute oil into bushings. Wipe up excess oil. 2. SELF-PROPELLED MODEL–Drain gasoline; refer to Draining Gasoline, page 17. 3. Set mower to highest height-of-cut setting (E). 4. Tip mower on its left side. Wipe grease fittings with clean rag (Fig. 27). Install grease gun onto fitting and gently apply one or two pumps of #2 Multi-Purpose Lithium Base Grease.
Maintenance 2. Drain gasoline; refer to Draining Gasoline, page 17. POTENTIAL HAZARD • Gasoline is extremely flammable, highly explosive and under certain conditions can cause personal injury or property damage. WHAT CAN HAPPEN • Tipping mower may cause fuel leakage from carburetor or fuel tank. HOW TO AVOID THE HAZARD • Avoid fuel spills by running engine dry or remove gas with hand pump, never siphon. 3. If grass bag is installed on mower, close door in mower housing and remove grass bag. 4.
Storage 1. For long term storage, it is recommended that gasoline be drained from fuel tank or use a fuel additive before storing. To drain gasoline, refer to Draining Gasoline. After fuel is drained, start engine and let it idle until all fuel is consumed and engine stops. If gasoline is not drained, gum–like varnish deposits will form and cause poor engine operation or even starting problems.
