CLEANING & MAINTENANCE

CAUTION: Make sure that the power head is unplugged from power source
before inserting or removing any attachments and before
cleaning.
Cleaning
• Do NOT immerse the power head into
water or any other liquid. Clean with a
damp sponge and cloth and wipe dry.
• The master prep pitcher, master prep
bowl and the chopping blades may be
cleaned in the upper basket of the
dishwasher.
• Use extreme caution when cleaning
the chopping blades as the blades are
very sharp.
• The splash guards and the storage
lids, may be washed in upper basket of
the dishwasher.
Hints & Tips:
• The double chopping blades can be
used for chopping meat, fish,
vegetables, cheese, etc.
• For finer chopping, increase the
length of time you process.
• For coarser chopping, use the pulse
button for a few seconds and monitor
food texture.
• Pre-cut larger pieces to make them fit
into the master prep bowl. When
chopping hard foods (e.g. meat,
cheese) cut into 1-inch cubes.
Trouble Shooting
Motor doesn't start or blades don't
rotate:
• Check that the plug is securely
inserted into the electrical outlet.
Food is unevenly chopped:
• Either you are chopping too much food
at one time, or the pieces are not small
enough. Try cutting the food into
smaller pieces of even size and
processing smaller amounts per batch.
Food is chopped too fine or is too
watery:
• The food has been over processed.
Use brief pulses or process for shorter
time. Let blades stop completely
between pulses.
Food collects on splash guard/safety
cover or on the sides of the master
prep pitcher or master prep bowl:
• You may be processing too much food.
Turn the machine off. When the
blades stop rotating, remove the power
head and the splash guard. Remove
some of the food being processed.
