No parts required – Assemble the grass bag. 2 Install the handle. 2 4 Note: Determine the left and right sides of the machine from the normal operating position.
3. Set the machine to the desired cutting height; refer to Adjusting the Cutting Height (page 12). 4. Stand behind the machine in the operating position to determine the handle height that is most comfortable for you (Figure 4). 6. Position the cable guard onto the handle with the cable(s) inside the guard, and secure the guard to the handle with the 2 carriage bolts and the 2 locknuts that you previously removed (Figure 3).
3. Remove the dipstick by rotating the cap counterclockwise and pulling it out. 4. Wipe the dipstick clean with a clean cloth. 5. Insert the dipstick into the filler neck, then remove the dipstick. 6. Read the oil level on the dipstick. • If the oil level is below the Add mark on the dipstick, slowly pour a small amount of oil into the oil-fill tube, wait 3 minutes, and repeat steps 4 through 6 until the oil level is at the Full mark on the dipstick.

Operation Note: Determine the left and right sides of the machine from the normal operating position. Each time before you mow, ensure that the self-propel drive and the blade-control bar operate properly. When you release the blade-control bar, the blade and the self-propel drive should stop. If they do not, contact an Authorized Service Dealer. CAUTION This machine produces sound levels in excess of 85dBA at the operator's ear and can cause hearing loss through extended periods of exposure.
Adjusting the Cutting Height engine damage which may not be covered under warranty. • Do not use gasoline containing methanol. You can change the cutting height at each wheel by adjusting a cutting-height lever. Cutting heights are 25 mm (1 inch), 38 mm (1-1/2 inches), 51 mm (2 inches), 64 mm (2-1/2 inches), 76 mm (3 inches), 89 mm (3-1/2 inches), 102 mm (4 inches), 114 mm (4-1/2 inches). • Do not store fuel either in the fuel tank or in fuel containers over the winter unless you use a fuel stabilizer.
Operating the Self-Propel Drive and Engaging the Cutting Blade Starting the Engine 1. Connect the spark-plug wire to the spark plug. 2. Open the fuel valve (Figure 14). This machine is equipped with a blade-brake clutch. Important: To ensure that the blade-brake clutch is working properly, refer to Checking the Blade-Brake Clutch (page 14). The machine has 3 ground speeds: 1 (slow), 2 (medium), and 3 (fast). The self-propel-drive lever is located below and behind the fuel tank (Figure 15).
Checking without the Grass Bag 1. 2. 3. 4. g019672 Figure 17 1. Move the blade-control bar to the right. Move the machine onto a paved surface in a non-windy area. Set all 4 wheels to the 76 mm (3 inch) cutting-height setting; refer to Adjusting the Cutting Height (page 12). Take a half sheet of newspaper and crumple it into a ball small enough to go under the machine housing (about 76 mm or 3 inches in diameter). Place the newspaper ball about 13 cm (5 inches) in front of the machine (Figure 18). 2.
Installing the Grass Bag the rear-discharge chute until the latch locks into place (Figure 19). 1. Stop the engine and wait for all moving parts to stop. 2.

Cutting Grass Operating Tips • Grass grows at different rates at different times of the year. In the summer heat, it is best to cut grass at the 64 mm (2-1/2 inch), 76 mm (3 inch), or 89 mm (3-1/2 inch) cutting-height settings. Cut only about a third of the grass blade at a time. Do not cut below the 64 mm (2-1/2 inch) setting unless the grass is sparse or it is late fall when grass growth begins to slow down.

Balancing the Blade 1. 2. 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 30). Install the new blade-brake cable, but do not tighten the cable clamp on the top of the mower housing (Figure 31). g002280 Figure 30 Note: You can also check the balance using a commercially manufactured blade balancer. 2.
4. greater than 8 mm (5/16 inch), the belt will not properly drive the blade. Cleaning Pull the cable tight to remove the slack (but do not stretch the cable spring) and tighten the cable clamp screw to lock the adjustment in place. Cleaning under the Machine 5. Remove the spacer. 6. Ensure that there is slack in the cable and a gap between the blade-brake-control lever and the control bracket when the self-propel-drive bar is not engaged. 7.
Note: The blade will draw in water and wash out the clippings. Let the water run until you no longer see clippings being washed out from under the machine. Cleaning under the Belt Cover 4. Stop the engine and wait for all moving parts to stop. Service Interval: Every 50 hours—Remove grass clippings and debris from under the belt cover. 5. Turn off the water. 1. 6.
