There are two hazards associated with the mix blades. First, the blades are driven
with substantial torque. Never place your hand in the mix chamber unless power is
completely disconnected and appropriate lock out/tag out procedures have been
followed. Second, the mix blades may become razor sharp. Always be careful when
touching or cleaning these blades. Check for sharp edges frequently. Replace
blade if a hazard exists.
