M3 Grinder User's Manual rev.7

Unpacking & Installation

Included with the grinder is a
power cord and a bag of hex.
Also a dowel pin for holding the
shaft when changing burrs.

Drive belt. The Grinder ships with the

belt installed. If you should
need to reinstall it, place the
drive belt into the groove of
the small pulley on top of the
grinder and stretch it around
the large pulley. This will take
some effort as the belt has
plenty of tension. It will
simplify the process of getting
the belt around the large
pulley if you begin by getting
the belt around one side of the
large pulley and then start to
rotate the large pulley in a
manner so as to drag this
around the front. This will drag the belt around the pulley.

Fuse. There is a fuse installed as shipped, and a spare included. Both are accessible
in a small plastic drawer in the connector where the power cord is inserted. Further
spares should be 5x20mm 2 amp slow-blow fuses. These are widely available at
local stores including Radio Shack. The only reason that a fuse may blow is if the
burrs are firmly touching, or a stone has got between the burrs. Stones are not
unusual in coffee beans.

Initial adjustment. The Grinder is shipped with the burrs adjusted so they are
touching. This does no harm to the burrs and ensures the center shaft is stabilized
in the event the Grinder receives a hard knock during shipping. Loosen the
adjustment lock knob by rotating it counterclockwise 1/4 turn or so. Now back the
Top Funnel counterclockwise a bit over 1/4 turn and

tighten the lock knob

. This

should be a starting point for a hand packed short pour.

The lock knob does need

to be

snugged down or it can loosen during grinding and cause the funnel to

rotate and lock down the burrs

.

Use. Turn on the grinder and then pour your measured amount of beans into the
top funnel.

Maintenance and Cleaning

General cleaning. Use a soft cloth or paper towel with alcohol or mild detergent
and water to clean the outside of the machine. The internal parts can stand
stronger solvents. Do not rub crossways on the bare grained aluminum parts! Do
not use abrasives anywhere!

The drive belt and the pulleys will get coated with dust and coffee grounds. They
will then occasionally slip instead of grinding. Remove the belt and clean it and the
pulleys with acetone - available from hardware stores.

Accessing the burrs.

The following might best be done with the power cord

removed and the grinder laying on its back.

Two screws and washers hold the
bottom funnel in place. These are
underneath the plate that holds the
top and bottom funnels - just to the
side of the bottom funnel where it
enters the aluminum plate. Remove
the screws and washers.

funnel area with the grinder upside
