Mower
An unbalanced blade
will cause excessive
vibration when rotat-
ing at high speeds. It
may cause damage
to mower, and could
break causing per-
sonal injury.
When removing
the cutting blade
for sharpening or
replacement or
when sliding the belt
around it, protect
your hands with a
pair of heavy gloves
or use a heavy rag to
hold the blade.
