injury. Always keep body parts (i.e. hands, feet) a safe 

distance away from moving parts. Ensure all covers and 

guards are securely in place before use.

Hot surfaces (i.e. the motor) may ignite flammable or 

combustible items and cause a fire or explosion, which 

can result in serious bodily injury. Keep the electric lawn 

mower + mulcher a safe distance away from flammable 

or combustible items until surfaces that are hot have 

completely cooled. Do not store the unit near flammable or 

combustible items.

A damaged blade or worn blade nut may break off the 

mower assembly and cause serious injury. Replace the 

damaged blade or blade nut before using the unit.
