Blade Sharpening
KEEP BLADE SHARP FOR BEST MOWER PERFORMANCE. A
DULL BLADE DOES NOT CUT GRASSCLEANLY.

WARNING: Use gloves and proper eye protection
while removing, sharpening, and installing blade.
Ensure that safety key and battery pack are removed.
NOTE: Harsh conditions (high outside temperature, slopes,
high grass, etc.) can overheat the transmission and activate
the thermal switch if your mowing pace is too slow. Increase
the mowing speed to improve the ventilation.
4. If after performing these actions the thermal switch
continues to shut down the power to the transmission
stop using the mower and contact your local dealer.
