Warranty Information
Refer to the engine manual for specific warranty details.
Starting the Engine: Ensure the fuel tank is full and the engine is properly oiled. Connect the spark plug wire. For a cold engine, set the engine speed lever to "-". For a warm engine, set it to "↔". Grip the stop control handle and pull the starter rope rapidly. Release the stop control handle to stop the engine. Always start the engine on a level surface, away from obstacles and with feet well away from the blade. Keep hands and feet away from rotating parts.
Operation: Grip the stop control handle firmly with both hands during operation. Releasing the handle will stop the engine. For PLM4611, grip the self-drive control handle to move forward. For PLM4612, select one of three speeds (3.0-4.5 km/h) using the speed adjustment system before engaging the self-drive handle.
Stopping the Engine: Release the stop control handle. Disconnect and ground the spark plug wire to prevent accidental starting.
Mulching: Clear the lawn of debris. Do not cut wet grass. Cut no more than 1/3 of the grass length. Adjust ground speed for even dispersal. Clean the mulching wedge and deck after each use.
Maintenance: Regularly clean the air filter. Check and sharpen the cutting blade. Tighten bolts and screws. Store the mower in a dry, clean area after preparing it for off-season storage.
