Please use isopropyl alcohol (not rubbing alcohol which contains oils) to clean the inner
surface of your bottom funnel if/when the grinder begins to retain grounds after the
motor is switched off.

Then wipe the supplied wax onto the entire inner surface of the bottom funnel.  Only a
small amount is necessary.  It will show up as a darkening of the surface.  Put a
polyethylene bag - like a sandwich bag - over your hand while it might contact the wax
in a wet form.  Leave the wax to dry for a couple of minutes, until it is no longer slightly
sticky.  Use a piece of paper towel (tee shirt cloth preferred) to buff the wax.  This wax
is entirely food grade.  The emulsifiers, which are the solvents that evaporate, are also
FDA approved, but may irritate the skin in liquid form.

In case of locking the burrs.

If you left the adjustment lock knob loose and the

grinder has locked the burrs, the circuit breaker may trip. Then to loosen the burrs
follow the procedure below.

Accessing the burrs.

The following is best done with the power cord removed and the

grinder lying on its back.

This is only necessary to do if you want to change the burrs or

back them off from being locked. We had been recommending changing burrs at 400
lbs. of beans but the SSP burrs that are installed are much more durable so we are not
sure of their life expectancy.

Two hollow internal hex nuts and
special slotted clips retain the bottom
funnel.  These are on either side where
the funnel fits into the middle aluminum
plate.  Slightly loosen each nut with a
3/16" hex key (supplied with the
grinder) and slide the clip outwards
away from the funnel.  Retighten the
nut to hold the clip clear of the funnel.

Be very careful!

When you lower the

bottom funnel, lower it almost all the
way to the baseplate, before bringing it
forward. If you do not, it is possible to
bend the "moving wiper" which sticks

down as far as the bottom opening in the bottom funnel.  Because this rotates with the
bottom burrs and may stop at any position, it is not always  visibly obvious. This wiper is
critical to the proper action of the grinder.
