ADDITIONAL PRECAUTIONS
• Coffee Grinder - This unit is
intended for household use only.
Any required servicing other than
normal cleaning and general user
maintenance procedures should be
performed by an authorized service
facility (See Page 14).
• Voltage Source - The grinder
operates on 120 vac, 1.5 amp, 60Hz,
line voltage only. Using any other
source could result in damage to
the unit.
• Operating Time - The unit motor
is thermally protected but use
should be limited to no more than
two successive grind cycles ("20
CUPS" setting) within a short period
of time. Additional grinds may be
performed at 10 minute intervals.
• Power Cord - A short power
supply cord is used on the coffee
grinder to reduce possible risks of
tripping over or becoming
entangled in a longer cord.
• Extension Cord - When an
extension cord is used, be sure to
select one with at least 16 gauge
wire. When connecting the cord
between the appliance and the
electrical outlet, be sure the cord is
arranged so it does not drape over
the counter top where it may be
pulled on by children or tripped
over by someone. Always use good
safety practices.
• Coffee Collector - When
grinding coffee, DO NOT allow the
coffee collector to overfill.
Overfilling can cause ground coffee
to back up into the grinding
mechanism and clog the unit.
UNPACKING AND INSPECTION
Remove the coffee grinder from
the carton along with all packing
materials. Discard the packing
materials. The Use and Care
Booklet should be thoroughly read
before using the grinder. Store the
cleaning brush in a suitable location
for later use. Check the unit over
for damage that could have
occurred during shipment. If any
damage is found, place the unit
back in the carton and return it
immediately to the place of
purchase for replacement.

PREPARATION FOR GRINDING
Before beginning to grind coffee for
the first time, take just a few
moments to become acquainted
with your new coffee grinder. This
may be a good time to read the
"COFFEE FUNDAMENTALS"
section on Page 12 of this booklet.
Be sure the coffee grinder is
unplugged for the following
procedures:
Step 1. Wipe the unit clean Before using the BUNN® Home
Coffee Grinder for the first time,
wipe any lint off all exposed surfaces
of the unit. Remove the hopper lid
and wipe all accessible surfaces with
a damp cloth. Remove the coffee
collector and wipe clean of lint.
When finished, reassemble the unit
and be sure the hopper is empty.
Step 2. Determine the proper
grind setting - The grinder has
been adjusted for “drip grind” at
the factory. To change, remove the
hopper lid and note the setting of
the arrow on the top of the Grind
Adjust Knob inside the hopper.
Note the raised dots at the base of
the knob. Turning the indicating
arrow counter-clockwise toward the
larger dots results in a coarser grind
and turning the knob clockwise
toward the smaller dots results in a
finer grind (Refer to the illustration
below). The knob can always be
returned to any previous grind
position later for repeatable quality
grind results. For safety reasons, the
grind setting should only be changed
when the hopper is empty with
power off.

WARNING
DO NOT reach below the GRIND
ADJUST knob while the unit is
running.
Step 3. Load hopper - Pour coffee
beans into the hopper and fill to the
desired level (See illustration
below). One of two approaches may
be used: (a) pre-weigh the beans for
a desired amount of fresh coffee to
be ground or (b) fill the hopper up
to its capacity (slightly over one
pound of coffee beans). With either
method, be sure to replace the
hopper lid to maintain coffee
freshness. You are now nearly ready
to grind. For a further detailed
explanation of the two grinding
methods, refer to the next section
at the top of Page 8.
Step 4. Observe the Operating
Knob - Before grinding your first
coffee, take a moment and become
familiar with the function of the
Operating Knob. This knob is
located on the front of the coffee
grinder (See illustration below).
Notice the dial is divided into
increments ranging between Off
and 20 cups. Each incremental
mark (labeled in cups of coffee) is
intended as a general setting. The
actual coffee output varies with the
blend of coffee beans and the grind
setting for the same amount
(weight) of coffee. Finer grinds
require higher cup settings while
coarser grinds use lower cup
settings. Generally, an “8 CUPS"
setting grinds enough for eight cups
of coffee at a drip grind setting.
NOTE:HIGHER SETTINGS = STRONGER COFFEE
LOWER SETTINGS = WEAKER COFFEE

GRINDING FRESH COFFEE
GENERAL - Now that you have read
the previous paragraph, you are
ready to begin grinding coffee the
way you like. After a little time and
effort, you will discover the
correct grind to produce your
perfect cup of coffee. Proceed as
outlined below.
CAUTION
During operation, if the motor
should stall, turn OPERATING
Knob to OFF immediately.
(See illustration below). Unless the
coffee collector is correctly placed
on the collector platform track
and pushed all the way to the
back, the coffee grinder will not
operate.
Step 3. Set OPERATING Knob There are two basic methods for
setting the OPERATING Knob
which is determined by the amount
of beans that are placed in the
hopper.
Step 1. Connect unit to power Connect the power cord of the
coffee grinder to a standard
grounded (3-pronged) 120 vac.
outlet.
Step 2. Insert coffee collector Make sure the ground coffee
collector is empty and inserted into
its proper position before starting
COLLECTOR

GUIDE
(Method 1) Manual grind - If a
measured amount of coffee beans
intended for immediate use is
poured into the hopper, then
simply turn the OPERATING Knob
to a high enough setting to
completely grind all of the beans.
When the grind is complete, as
noted by the change in sound
(tone) of the coffee grinder motor,
Grinding CoffeeChecking Coffee Collector

turn the OPERATING Knob to OFF.
The ground coffee is ready for
brewing. Empty the coffee collector
into the brewing filter.
(Method 2) Automatic Grind - If
the hopper has sufficient amount
of coffee beans, the OPERATING
Knob can be set to automatically
grind the desired amount of coffee
for brewing. To determine the
correct grind setting for your taste,
some experimenting may be
required. Begin by setting the
OPERATING Knob for “8 CUPS”.
If this proves to be too weak,
increase the setting (toward 12) for
next grind. Conversely, if the coffee
is too strong, reduce the setting
(toward 4). When the grind is
finished, the unit automatically
shuts off. Once the right setting is
obtained, coffee results are very
repeatable.
Many factors affect the output of
ground coffee; the bean itself, the
type of roast, and the size of the
grind. A change in humidity also
affects the output. Since humid
conditions swell the coffee bean,
less weight is ground. You should
experiment with different settings
and grinds until the results are
perfected to your taste.
Chaff in coffee - Chaff is the
parchment or hull portion of the
coffee bean found in the cavity
which is released during the
grinding process (See illustration
below). Chaff seen in the ground
coffee does not have any adverse
effects on coffee flavor. Chaff results
from small amounts of the coffee
bean hull still on the bean when
ground. Some coffee beans yield a
higher level of chaff than others.

COFFEE FUNDAMENTALS
The process of brewing delicious
coffee is very similar to the
preparation of any other favorite
food item in that it requires a good
recipe. Proper brewing techniques
require precise control of the
following functions; the water
temperature, volume of water, and
the proper brew time. All Bunn
coffee makers are designed to
perform these functions perfectly.
Other important components to the
recipe are the type of grind and
amount of coffee used.
The actual amount of coffee required is generally determined by
the grind setting. The finer (smaller
particles) grinds require less coffee.
For best results, we recommend
using a drip (medium) grind and a
liberal amount of coffee (2 oz. for a
full 48 ounce pot of water). Using
too small an amount of coffee can
cause over-extraction and bitterness.
The terms Bitterness and Strength
are often confused. Coffee strength
increases as the amount of coffee
increases. Conversely, Coffee
bitterness increases as the amount
of coffee used decreases. This is the
direct result of coffee over
extraction.
Your new Bunn® grinder allows you
to grind coffee exactly as you like it,
and when combined with a Bunn
Coffee Brewer, you will have perfect
coffee every time.
✔ Blending Beans - Coffee beans
are generally named by country of
®
origin and are graded for quality by
physical appearance and taste.
✔ Roasting Methods - The type
of beans and the method of roasting
determines the flavor and aroma.
Chemical changes during roasting
yields the various roasts ranging
from light to dark. The most
common roast in America is a light
roast which has a milder flavor than
a darker roast. The darkest roast is
characterized by a heavier flavor
and aroma. The longer roasting time
brings out the oils to create a heavier,
more caramelized flavor.
✔ Types of Grinding - The finer
the grind of coffee, the greater the
surface area exposed to water which
results in a greater degree of
extraction. A coarse grind exposes
less coffee bean surface and
therefore reduces the degree of
extraction.
®
12
✔ Brewing - Good coffee is the
direct result of proper brewing
methods. The difference between a
poor blend of coffee and a fine blend
of coffee is very small when the
coffee is improperly prepared.
However, when it is properly
prepared, the difference becomes
very dramatic.
The basic process for brewing coffee
is the extraction of desirable coffee
flavor and aroma by the use of hot
water. However, making good
coffee requires considerable
experience and care. Some basic
requirements for proper coffee
preparation include the following:
1) Clean Equipment - Brewing
equipment should be thoroughly
cleaned and completely free from
contamination and off-odors.
2) Good Water - For coffee
brewing, water should be cleaned
and good tasting. If necessary, it
may be purified through an activated
carbon filter water conditioner to
remove sediment, foreign taste and
odors.
3) Accurate Temperature - The
temperature of the water is very
important and is carefully
maintained by the Bunn® Coffee
Brewer for both brewing and
holding coffee on the warmer.
4) Proper Grind - The correct
coffee grind is one that permits the
water to pass through the coffee
grounds in the correct time with
the minimum amount of sediment.
The Bunn® BCG coffee grinder does
allow you to grind coffee perfectly
time after time.
5) Fresh Ground Coffee - Using
fresh ground coffee ensures
maximum flavor and aroma.
6) Best Formula - A common
formula for good results using a drip
(medium) grind is 2 ounces of coffee
for a full 48 ounce pot of water.
However, the real criteria is personal
taste.
13
COFFEE STORAGE
Coffee beans stored in your Bunn
Coffee Grinder will remain fully
fresh for several days. However,
coffee does begin to lose flavor and
aroma as soon as it is ground.
Therefore, it is recommended that
only enough coffee for brewing is
ground at one time. Roasted bean
coffee has a much longer shelf life
than that of ground coffee.
®
The storage area should be cool,
dry, clean and free from outside
odors. Do not store next to heating
units, or in proximity to foods (such
as onions) with strong odors. If the
coffee is to be stored in the
refrigerator, it should be placed in
a covered container.
