  If your Grizzly Lawn Mower engine doesn't start, it might be due to several reasons: * The petrol tank may be empty, so you should fill it with petrol. * The starting sequence may be incorrect; refer to the operation instructions. * The spark plug connector may not be correctly attached, or the spark plug might be sooted. Attach the spark plug connector and clean, adjust, or replace the spark plug. * The carburetor mix may be incorrectly adjusted, requiring adjustment by a specialist workshop. * The battery may be empty, so you should charge it.

  If your Grizzly Lawn Mower overheats, it could be due to blocked ventilation holes. Clean the ventilation slot. Another potential cause is an incorrect spark plug, which should be changed. Also, check the engine oil level and fill with engine oil if it's too low.
