Installing the Starter Rope Assembly Pull the starter rope through the rope guide on the handle (Fig. 3). Note: Determine the left and right sides of the machine from the normal operating position. Installing the Handle 2 1. Mount the handle to the outside of the lawn mower housing (using the bottom hole) with 2 5/16–18 x 1–1/4 in. cap screws, washers, and thin nylon insert locknuts. 1 2. Secure the handle latches to the handle with 2 cap screws (5/16–18 x 1-1/2 in.
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. 7). 4. Remove the red cap from the end of the fuel line and from the end of the elbow fitting on the fuel tank (Fig. 5). 2 3 1 m-7283 1 m-1915 Figure 5 1. Fuel line 2. Elbow fitting Figure 7 3.

Note: When the crankcase is empty, pour about 3/4 of the crankcase capacity of oil in the crankcase, then follow the procedure in this section. Danger 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. To add oil: 1. Move the lawn mower to a level surface. 2. Clean around the dipstick (Fig. 8). • Fill the fuel tank outdoors, in an open area, and when the engine is cold.
Use a fuel stabilizer/conditioner regularly during operation and storage. A stabilizer/conditioner cleans the engine during operation and prevents gum-like varnish deposits from forming in the engine during periods of storage. Operation Important Do not use fuel additives other than a fuel stabilizer/conditioner . Do not use fuel stabilizers with an alcohol base such as ethanol, methanol, or isopropanol.
Starting the Engine Operating the Blade and the Self-Propel Drive 1. Connect the wire to the spark plug (Fig. 12). Note: The self-propel features are for the self-propel model only. 1. Have the blade control bail in the A position (Fig. 14). 1 C B A m-7280 Figure 12 1. Spark-plug wire m-3769 Figure 14 2. Open the fuel valve (Fig. 9). 3. Move the throttle control to the (Fig. 11). 2. Slide the blade control bail to the right and raise it to the B position to engage the blade (Fig. 14).
Using the Discharge Tunnel Plug Using the Grass Bag Occasionally, you may wish to use the grass bag for bagging extra long grass, lush grass, or leaves. 1. Stop the engine and wait for all moving parts to stop. 2. Insert the plug; refer to Installing the Discharge Tunnel Plug on page 7. Installing the Grass Bag 3. To remove the plug, move the discharge door handle rearward and lift up the spring clip on the bottom of the plug. When the plug is unlocked, pull it out of the discharge tunnel. 1.
Mowing with the Grass Bag Operating Tips • Review the safety instructions and read this manual carefully before operating the lawn mower. Warning • Clear the area of sticks, stones, wire, branches, and other debris that the blade could hit and throw. A worn grass bag could allow small stones and other similar debris to be thrown in the operator’s or bystander’s direction and result in serious personal injury or death to the operator or bystanders.
Cutting Grass • Grass grows at different rates at different times of the year. In the summer heat, it is best to cut grass at the 2 inch (51 mm), 2-1/2 inch (64 mm), or 3 inch (76 mm) cutting height settings. Cut only about a third of the grass blade at a time. Do not cut below the 2 inch (51 mm) setting unless the grass is sparse or it is late fall when grass growth begins to slow down.
Maintenance Note: Determine the left and right sides of the machine from the normal operating position. Recommended Maintenance Schedule Maintenance Service Interval Maintenance Procedure Each Use • Check the engine oil level. • Check the stopping time of the blade brake. The blade must stop within 3 seconds of releasing the bail; if it does not, contact an Authorized Service Dealer for repair. • Remove grass clippings and dirt from under the housing.
Caution If you leave the wire on the spark plug, someone could accidently start the engine and seriously injure you or other bystanders. Disconnect the wire from the spark plug before you do any maintenance. Set the wire aside so that it does not accidently contact the spark plug. Checking the Engine Oil Level 3. Hold the running garden hose at handle level and direct the water to flow on the ground just in front of the right rear tire (Fig. 19).
4. Remove the dirt and grass clippings with a hardwood scraper. Avoid burrs and sharp edges. 3. Remove the screw that secures the air cleaner cover (Fig. 20). 5. Turn the lawn mower upright. 6. Fill the fuel tank. 3 7. Connect the wire to the spark plug. Cleaning the Discharge Tunnel and Plug 1 m-7282 Remove the plug from the discharge tunnel and clean it after each use. 2 Figure 20 Always be sure that the discharge tunnel door closes securely when you release the handle.
Changing the Engine Oil Maintaining the Cutting Blade Change the oil after the first 8 operating hours and than after every 50 operating hours or every season (more frequently in dusty or dirty conditions). Always mow with a sharp blade. A sharp blade cuts cleanly and without tearing or shredding the grass blades. 1. Stop the engine and wait for all moving parts to stop. 1. Run the engine to warm the engine oil. 2. Disconnect the wire from the spark plug (Fig. 12).
Note: For the best performance, install a new blade before the cutting season begins. During the year, file down any small nicks to maintain the cutting edge. 2. If either end of the blade rotates downward, file that end (not the cutting edge or the end near the cutting edge). The blade is properly balanced when neither end drops.
Cleaning under the Belt Cover Adjusting the Self-propel Drive Self-propel Model only Self-propel Model only Keep the area under the belt cover free of debris. If the lawn mower does not self-propel or has a tendency to creep forward when the control bar is more than 1-1/2 inches (3.8 cm) from the handle, adjust the wheel drive control knob on the rear of the gear box. 1. Stop the engine and wait for all moving parts to stop. 2. Remove the bolts that secure the belt cover (Fig.
Servicing the Spark Plug Warning Check the spark plug after every 100 operating hours. Use an NGK BPR5ES spark plug or equivalent. Oil may be hot after the engine has been run, and contact with hot oil can cause sever personal injury. 1. Stop the engine and wait for all moving parts to stop. 2. Disconnect the wire from the spark plug (Fig. 12). Avoid contacting the hot engine oil when you drain it. 3. Clean around the spark plug. 4. Remove the spark plug from the cylinder head. 2.
Lubricating the Gear Case Hand-push Model only A. Loosen the jam nut on the blade brake cable (Fig. 34). After every 100 operating hours, grease the gear case. 1. Remove the grass bag. 1 2.

Servicing the Wheels 6. Install the 2 cap screws and 2 locknuts previously removed in the remaining holes in the wheel halves and tighten. Remove the 2 long screws or bolts and replace them with 2 cap screws and 2 locknuts (Fig. 36). Removing the Wheels 1. Stop the engine and wait for all moving parts to stop. 7. Install the wheel to the pivot arm with the cap screws, a spacer, and a locknut. Ensure that the spacer is positioned between the wheel hub and the pivot arm (Fig. 36). 2.
Preparing the Engine Removing the Lawn Mower from Storage 1. While the engine is still warm, change the oil from the crankcase. Refer to Changing the Engine Oil on page 17. 1. Check and tighten all fasteners. 2. Remove the spark plug and spin the engine rapidly using the starter to blow excess oil from the cylinder. 2. Remove the spark plug (Fig. 12). 3.
