This lawn mower is capable of amputating hands and feet and of throwing objects. Failure to observe the following safety instructions could result in serious injury or death. This manual identifies potential hazards and has special safety messages that help you and others avoid personal injury and even death. Danger, Warning, and Caution are signal words used to identify the level of hazard. However, regardless of the hazard, be extremely careful.
– Refuel outdoors only and do not smoke while refuelling. • Disengage all blade and drive clutches before starting the engine. – Add fuel before starting the engine. Never remove the cap of the fuel tank or add gasoline while the engine is running or when the engine is hot. • Start the engine carefully according to instructions and with feet well away from the blade(s). • Do not tilt the lawn mower when starting the engine, unless you must tilt the lawn mower to start it.
• Do not mow on wet grass. Reduced footing could cause slipping. Sound Pressure Maintenance and Storage This unit has a maximum sound pressure level at the operator’s ear of 84 dBA, based on measurements of identical machines per Directive 98/37/EC. • Keep all nuts, bolts (especially blade attachment bolts), and screws tight to ensure that the lawn mower is in safe working condition.
Safety and Instruction Decals Safety decals and instructions are easily visible to the operator and are located near any area of potential danger. Replace any decal that is damaged or lost. 100-4355 1. Cutting height settings 93-4105 1. Warning—read the Operator’s Manual. 2.

7. If the oil level reading is below the Add mark on the dipstick, slowly pour only enough oil into the filler hole to raise the oil level to the Full mark on the dipstick. Danger 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. Important Do not overfill the crankcase with oil and run the engine; engine damage will result.
Reviewing the Maintenance Schedule Note: Do not use the primer to start a warm engine after a brief shutdown. However, cool weather may require you to prime the engine again. Review the Recommended Maintenance Schedule on page 14. You may need to perform one or more additional procedures before or soon after you begin operating the lawn mower. 3. Hold the blade control bail against the upper handle (Fig. 12).
Using the Self-propel Drive setting and walk slower; then cut the grass again at a normal setting. Mowing the grass when it is too long can plug the lawn mower and cause the engine to stall. To operate the self-propel drive, simply walk forward with your hands on the upper handle and your elbows at your sides, and the lawn mower will automatically keep pace with you. The faster you walk, the farther the handle will slide and the faster the lawn mower will propel (Fig. 14).
Using the Grass Bag Danger Occasionally, you may want to use the grass bag for bagging lush grass or collecting leaves. If the rear door does not close completely, the lawn mower could throw objects, causing serious personal injury or death. Installing the Grass Bag If you cannot close the rear door because the grass clippings clog the discharge area, stop the engine, wait for all moving parts to stop, and remove the grass clippings (with a stick, not your hand) until the rear door closes completely.
Danger Warning If the rear door does not close completely, the lawn mower could throw objects, causing serious personal injury or death. Operating a lawn mower with its engine running at a speed greater than the factory setting can cause the lawn 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.
Maintenance Note: Determine the left and right sides of the machine from the normal operating position. Recommended Maintenance Schedule Maintenance Service Interval Each Use 2Change • Check the engine oil level. Refer to Checking the Engine Oil Level on page 15. • Check the stopping time of the blade brake. The blade must stop within 3 seconds of releasing the bail; if it does not, contact an Authorized Service Dealer for repair. • Remove grass clippings and dirt from under the housing.
Checking the Engine Oil Level 3. Lift the rear door and attach the coupling to the lawn mower washout fitting on the recycling plug (Fig. 21). Before you use the lawn mower, ensure that the oil level is between the Add and the Full marks as shown on the dipstick (Fig. 8). If the oil level is below the Add mark, add oil. Refer to Filling the Crankcase with Oil on page 8. Cleaning under the Housing 2 Keep the underside of the housing clean. Be especially careful to keep the kickers free of debris (Fig.
