Safety This machine meets or exceeds the Never leave a running machine unattended. Always turn off blades, set paring brake, stop engine, and remove key before dismounting. • Turn off blades when not mowing. Stop the engine and wait for all parts to come to a complete stop before cleaning the machine, removing the grass catcher or unclogging the discharge chute. • Operate the machine only in daylight or good artificial light.
Removeor markobstaclessuchasrocks,treelimbs, etc. from the movdngarea.Tall grasscanhide obstacles. Avoidsuddenstartswhenmovdnguphillbecause the mowermaytip backwards. Be aware that loss of traction may occur going downhill. Weight transfer to the front wheels may cause drive wheels to slip and cause loss of brak:ing and steering. Ahvays avoid sudden starting or stopping on a slope. If tires lose traction, disengage the blades and proceed slovdy off the slope.
General • Service: Never operate a machine inside a closed area. Engine exhaust contains carbon monoxide, which is an odorless, deadly poison that can _ll you. • Keep nuts and bolts tight, especially the blade attachment bolts. Keep equipment in good condition. • Never tamper with safeff devices. Check their proper operation regularly. • Keep the machine free of grass, leaves, or other debris build-up. Clean up oil or fuel spillage fuel soaked debris. Allow the machine to cool before storing.

Maintain the air pressure in the front and rear tires as specified. Uneven tire pressure can cause uneven cut. Check the pressure at the wflve stem (Figure 39). Check the tires when they are cold to get the most accurate pressure reading. Figure 38 1. Every 25 hours--Check Return the control panel to its original position.
Mower Maintenance Servicing the Cutting Blades 4 2 Maintain sharp blades throughout the cutting season because sharp blades cut cleanly without tearing or shredding the grass blades. Tearing and shredding turns grass brown at the edges, which slows growth and increases the chance of disease. G006530 Figure 1. 2. Check the cutter blades daily for sharpness, and for any wear or damage.

Rotate the same blade 180 degrees so that the opposing cutting edge is now in the same position.
Leveling the Mower Deck Check to ensure the mower deck is level any time you install the mower or when you see an uneven cut on your lawn. 5 The mower deck must be checked for bent blades 4 prior to leveling; any bent blades must be removed and replaced. Refer to the Checking for Bent Blades procedure before continuing. G000551 Figure 45 1. 2. 3. Sail area of blade Blade Curved washer Sharpening 4. 5.

Mower Belt Maintenance Inspecting the Belts Service Interval: Every 25 hours--Check wear/cracks. the belts for Check the belts for cracks, frayed edges, burn marks, or any other damage. Replace damaged belts. Replacing the Mower Belt 3 Squealing when the belt is rotating, blades slipping when cutting grass, frayed belt edges, burn marks and cracks are signs of a worn mower belt• Contact an Authorized Service Dealer to replace the mower belt if aW of these conditions are evident.

Important: gasoline Do not store stabilizer/conditioned over 30 days. 11. Remove the spark plug(s) and check its condition; refer to Servicing the Spark Plug in the Engine Maintenance section. With the spark plug(s) removed from the engine, pour two tablespoons of engine oil into the spark plug hole. Use the starter to crank the engine and distribute the oil inside the cylinder. Install the spark plug(s). Do not install the wire on the spark plug(s). 12.
Troubleshooting Problem The engine overheats. Possible Cause Action 1. The engine load is excessive. 1. Reduce ground speed. 2. The oil level in the crankcase is low. 2. Add oil to the crankcase. 3. Remove the obstruction from the cooling fins and air passages. 3. The cooling fins and air passages under the engine blower housing are plugged. The starter does not crank Corrective 4. The air cleaner is dirty. 4. Clean or replace the air cleaner element. 5.
Problem There is abnormal vibration. Uneven cutting height. Possible Cause Action 1. The engine mounting bolts are loose. 1. Tighten the engine mounting bolts. 2. The engine pulley, idler pulley, or blade pulley is loose. 3. The engine pulley is damaged. 2. Tighten the appropriate pulley. 4. The cutting blade(s) is/are bent or unbalanced. 4. Install a new cutting blade(s). 5. A blade mounting bolt is loose. 6. A blade spindle is bent. 5. Tighten the blade mounting bolt. 6.
