Product Overview Hour Meter The hour meter records the number of hours the engine has operated. It operates when the engine is running. Use these times for scheduling regular maintenance (Figure 4). Glow Plug Light (Orange Light) The glow plug indicator light turns on when the ignition switch is turned to the on position. When the light turns off, the engine is ready to be started (Figure 4). Water in Fuel Light (Red Light) The water in fuel light turns on when there is water in the fuel.
Operation In certain conditions, fuel is extremely flammable and highly explosive. A fire or explosion from fuel can burn you and others and can damage property. Note: Determine the left and right sides of the machine from the normal operating position. Adding Fuel • Fill the fuel tank outdoors, in an open area, when the engine is cold. Wipe up any fuel that spills. The engine runs on clean, fresh diesel fuel with a minimum octane rating of 40.
2. Clean around each fuel tank cap and remove the cap. Add fuel to both fuel tanks, until the level is 1/4 to 1/2 inch (6 to 13 mm) below the bottom of the filler neck. This space in the tank allows the fuel to expand. Do not fill the fuel tanks completely full. 3. Install fuel tank caps securely. Wipe up any fuel that may have spilled. 4. If possible, fill the fuel tank after each use. This will minimize possible buildup of condensation inside the fuel tank. Figure 5 Checking the Engine Oil Level 1.

uneven ground. However, the cutting height used in the past is generally the best one to use. When cutting grass longer than six inches tall, you may want to cut the lawn twice to ensure an acceptable quality of cut. Parking brake may not hold machine parked on Z Stand and could cause personal injury or property damage. Cut 1/3 of the Grass Blade Do not park on Z Stand unless wheels are chocked or blocked. It is best to cut only about 1/3 of the grass blade.
Keep the Underside of the Mower Clean Clean clippings and dirt from the underside of the mower after each use. If grass and dirt build up inside the mower, cutting quality will eventually become unsatisfactory. Blade Maintenance Maintain a sharp blade throughout the cutting season because a sharp blade cuts 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.
