Troubleshooting
Engine won't start
Ensure there is fuel in the tank, the spark plug is connected, the choke is set correctly, and the throttle is in the 'start' position. Check oil level.
Engine runs rough or stalls
Check the air filter for blockages. Ensure fresh fuel is being used. Clean the spark plug or replace it if fouled.
Self-propel system not engaging
Verify the drive cable is properly connected and adjusted. Ensure the drive belt is intact and tensioned correctly.
Poor cutting performance
Check if the blade is sharp and free from damage. Ensure the cutting height is set appropriately and the deck is clear of debris.
Grass clippings not being collected efficiently
Empty the grass collector regularly. Ensure the discharge chute is not blocked and the mulching plug is removed if collecting.
