Operation Note: Determine the left and right sides of the machine from the normal operating position. 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. If it does not, contact an Authorized Service Dealer. This machine produces sound levels in excess of 85dBA at the operator’s ear and can cause hearing loss through extended periods of exposure.
Filling the Fuel Tank with Gasoline When fueling, under certain circumstances, a static charge can develop, igniting the gasoline. A fire or explosion from gasoline can burn you and others and damage property. For best results, use clean, fresh, lead-free gasoline with an octane rating of 87 or higher. To ensure freshness, purchase only the quantity of gasoline that you expect to use in 30 days. Using unleaded gasoline results in fewer combustion deposits and longer engine life.
Stopping the Engine 1. Move the throttle control to the Stop position. 2. Disconnect the wire from the spark plug if you do not use the lawn mower or leave it unattended. Operating the Blade Engaging the Blade When you start your engine, the blade does not turn. You must engage the blade to mow. 1. Push the control bar lock forward (Figure 12). Figure 11 1. Oil fill/dipstick 2. Fuel tank cap 3. Air cleaner 4. Spark plug 2. Remove the cap from the tank. 3.
Checking the Blade Brake Clutch 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. Check the blade control bar before each use to ensure that the blade brake clutch system is operating properly. Operating the Traction Drive 1. Install the empty grass bag on the discharge tunnel. Engaging the Traction Drive 3.
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 16) and move it to the desired setting. Figure 17 1. Rear door 3. Install the bag on the bag mounting posts (Figure 18). Figure 16 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.

to adjust the cable adjuster to achieve this value (Figure 27). 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. 1. Stop the engine and wait for all moving parts to stop. 2. Disconnect the wire from the spark plug (Figure 11). Figure 31 3. Drain the gasoline from the fuel tank; refer to Emptying the Fuel Tank and Cleaning the Fuel Filter. 3. Wear 4. Slot formed 1. Sail 2. Flat part of the blade 4. Tip the mower onto its right side (Figure 30).
Balancing the Blade Cleaning 1. Check the balance of the blade by placing the center hole of the blade over a nail or screwdriver shank clamped horizontally in a vise (Figure 33). Cleaning under the Mower Housing To ensure the best performance, keep the underside of the mower housing clean. Washing Method Figure 33 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. Gasoline 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 gasoline 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 35 5. Return the mower to its operating position. 1.
