Operation 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. Note: Determine the left and right sides of the machine from the normal operating position. 1. Move the lawn mower to a level surface. 2. Clean around the dipstick (Figure 10). Each time before you mow, make sure that the self-propel drive and the blade control bar operate properly. When you release the blade control bar, the blade should stop.
Filling the Fuel Tank For best results, use clean, fresh, lead-free petrol with an octane rating of 87 or higher. To ensure freshness, purchase only the quantity of petrol that you expect to use in 30 days. Using unleaded petrol results in fewer combustion deposits and longer engine life. You may use leaded petrol if unleaded petrol is not available. In certain conditions, petrol is extremely flammable and highly explosive. A fire or explosion from petrol can burn you and others and can damage property.
Operating the Blade Important: Do not fill the tank more than 1/4 inch (6 mm) from the top of the tank because the petrol must have room to expand. Engaging the Blade 4. Install the fuel tank cap and wipe up any spilled petrol. When you start your engine, the blade does not turn. You must engage the blade to mow. Starting the Engine 1. Push the control bar lock forward (Figure 14). 1. Connect the wire to the spark plug (Figure 12). Figure 12 1. Spark-plug wire 2.
Disengaging the Blade Disengaging the Traction Drive Release the blade control bar. Release the traction control bar. Important: When you release the blade control bar, the blade should stop within 3 seconds. If it does not stop properly, stop using your mower immediately and contact an Authorized Service Dealer. Checking the Blade Brake Clutch Check the blade control bar before each use to ensure that the blade brake clutch system is operating properly.
Adjusting the cutting height levers could bring your hands into contact with a moving blade and result in serious injury. • Stop the engine and wait for all movement to stop before adjusting the cutting height. • Do not put your fingers under the housing when adjusting the cutting height. 1. Pull the wheel height adjustment lever toward the wheel (Figure 18) and move it to the desired setting. Figure 19 1. Rear door 3. Install the bag on the bag mounting posts (Figure 20). Figure 18 1.
Mowing with the Grass Bag Operating a mower with its engine running at a speed greater than the factory setting can cause the mower to throw a part of the blade or engine into the operator’s or bystander’s area and result in serious personal injury or death. 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. – Do not change the engine speed setting.
• For light leaf coverage, set all the wheels at the same cutting height setting. • If there are more than 5 inches (12.7 cm) of leaves on the lawn, set the front cutting height 1 or 2 notches higher than the rear cutting height. This makes it easier to feed the leaves under the mower housing. • Slow down your mowing speed if the mower does not cut the leaves finely enough. • If you mow over oak leaves, you can add lime to the grass in the spring to reduce the acidity of the oak leaves.
Maintenance Note: Determine the left and right sides of the machine from the normal operating position. Recommended Maintenance Schedule(s) Maintenance Service Interval Maintenance Procedure After the first 8 hours • Change the engine oil.

Controls System Maintenance halves together. Mount the screws or bolts in the opposing holes (Figure 31). 5. Check the alignment of all parts and tighten the screws, alternating from side to side for a uniform fit, until the wheel halves are drawn together (Figure 31). Adjusting the Blade Brake Cable 6. Install the 2 bolts 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 bolts and 2 locknuts (Figure 31).
Do not overtighten the blade brake cable. Overtightening the blade brake cable could prevent the blade brake from contacting the brake drum when you release the control bar. If the blade brake does not contact the brake drum, the blade will not stop rotating, which could cause serious personal injury. • Each time you adjust the brake cable, ensure that the brake stops the blade in 3 seconds or less.
Blade Maintenance Maintaining the Cutting Blade Always mow with a sharp blade. A sharp blade cuts cleanly and without tearing or shredding the grass blades. Complete the following procedure before inspecting, removing, or installing the blade: Figure 36 1. Stop the engine and wait for all moving parts to stop. 3. Wear 4. Slot formed 1. Sail 2.

Cleaning under the Mower Housing To ensure the best performance, keep the underside of the mower housing clean. Washing Method Figure 38 Service Interval: Before each use or daily 1. Position the mower on a flat concrete or asphalt surface near a garden hose.
Tipping the mower may cause the fuel to leak from the carburetor or the fuel tank. Petrol is extremely flammable, highly explosive, and, under certain conditions, can cause personal injury or property damage. Avoid fuel spills by running the engine dry or by removing the petrol with a hand pump; never siphon. 3. Tip the mower onto its right side. 4. Remove the dirt and grass clippings with a hardwood scraper. Avoid burrs and sharp edges. Figure 40 5. Return the mower to its operating position. 1.
