1 - Locate. Find a flat, dry counter space with access to a
power outlet. The KEY is made to be usable in 100v - 240v
regions without the need for a separate transformer. It uses
a C13 style cable (such as a computer) that can be
purchased locally as needed. A US-style 3 prong cable is
included inbox.
2 - Remove from box. Using both hands, carefully pull the
KEY straight out of the packaging. Use caution when pulling
it out -- it is heavy.
3 - Attach Magic/Static wiper. Lay the grinder on its side
on a clean towel or cloth, using the 5mm hex key (included)
remove the screw holding the lower axle cap in place.
Remove the axle cap and store for safekeeping. You may
need to dump some coffee beans into funnel and use a
rubber glove to hold the shaft securely enough to remove
the screw (tapping the end of the allen key abruptly will
also help). Re-use screw and thread through washer and
wiper, then using the 5mm hex key, tighten screw securely
in place.
If the bottom bolt is stuck and cannot be
removed (the shaft turns with it), you can
remove the gearbox cover and place a metal
rod (or Allen key) through the hole in the
shaft to lock it in place. This should be a
last resort method.
the magic wiper has a replaceable stirring
rod in case it gets bent or damaged. Push
out the insert block on backside of wiper
(needs to be removed from machine) to
swap the stirring attachment.
Choose magic tumbler or standard tumbler wiper

4. Set burr mount to zero. Lift the locking ring until it
clears the burr collar pins, while holding the locking ring
rotate the burr mount clockwise until the inner and outer
burrs touch ... this is the zero point.
•Note: Do NOT attempt to use or rotate the flywheel at
the zero point. This could cause premature burr wear.
5 - Dial in grind. From the zero point, rotate the
locking ring counter-clockwise 1.75 turns (630 degrees).
This is a good starting point for espresso, but will likely
require further adjustment depending on your beans and
setup. For pour-over, another full turn in the larger
direction is a good starting point. Lower the locking ring
onto the burr collar pins.
IMPORTANT! Verify the locking ring sits flush with the burr
collar, and the pins are completely engaged. Try to rotate
the locking ring to ensure the burrs are locked. If you
operate the grinder with the locking ring improperly secured,
you could potentially seize the machine.

Magic tumbler: Ensure the tumbler plug is properly
seated inside the magic tumbler, then attach the magic
tumbler on the magnetic mount, being careful not to
damage the static wiper or the stirring rods. This gets
easy with practice.
Standard tumbler: Attach the lower funnel on the
magnetic mount. Ensure the tumbler plug is properly
seated inside the standard tumbler. Center the tumbler
directly beneath the lower funnel. It will self-center with
the magnets.
6. Choosing and placing tumbler.

7 - Plug in unit. Use the included power cord. You may
need an adapter or another C13 style cable for your
country, but a transformer should not be needed as it
works anywhere with a 100v-240v (50 or 60Hz) supply.
8 - Power on mains. This is the switch on the back of the
unit next to where the cord plugs in.
9 - Adjust the RPM level. Turn the knob counterclockwise
to reduce to the 50 -70 RPM range (a good starting point).
10 - Using the On/Off Button. When the burrs are
spinning, the button will illuminate and remain depressed.
Be sure not to leave the grinder ON/Spinning for
excessive periods of time.
11 - Adjust the Grind. Test grind a small amount of
coffee to verify the initial setting. We usually ship with the
grinder close to an espresso setting, but it will need to be
adjusted for your brewing style and particular coffee.
Adjustments coarser and finer are done by lifting up the
locking ring and turning. Larger numbers mean larger
particles. There is no absolute zero. There may be some
small remnants of beans in the grinder during shipping, as
we test grind ~200g of coffee on each unit before
shipping. While we do clean, small amounts may remain
during shipping.

12 - Grinding Coffee. When you are dialed into your grind
size, you can dump your coffee dose into the Bean Dish.
You may use either a "Hot Start" where the grinder is
on/spinning before the beans are introduced, or a "Cold
Start" where the beans are added before turning the
grinder on.We typically recommend using a Hot Start when
operating the KEY. A typical dose takes around 10-20s for a
20g dose to finish grinding (depending on grind size and
RPM setting).
13 - Power Off.We recommend powering down at mains
overnight for cafes, or during any prolonged period without
use at the home.
14 - Cleaning the Grinder. Use brush to clean the burr,
funnel, base-plate, etc. To replace brush in handle, first pull
brass outer sleeve to cover bristles before re-insertion. Upon
re-insertion, the cap will be pushed back for immediate use
upon removal
