The blade switch engages the electric clutch when
pulled out to the “ON” position. When the blade switch
is in the “ON” position the cutting blade(s) are

clutch when the blade switch is pushed in to the “OFF”
position. When the blade switch is in the “OFF”
position the cutting blade(s) are disengaged. The
