FOAM INSERTS —
INSTALLATION

1. Remove lid. Remove bag of inserts.

2. Looking down into the hopper, observe the small nylon pin piercing the left side of the measuring drum.

3. Now turn unit on its back (see Figure 1.).

4. Using a knife blade or thin screw driver, slide the blade under the head of the pin and pry out the nylon pin.

5. Pull handle to DOWN position and carefully, place into drum opening, one of the foam inserts (as shown in Figure

2.). Each insert is marked with the quantity, in ounces, that it will dispense (the smaller the insert, the more coffee
dispensed from the unit).

6. Replace nylon pin. Press firmly on the head until it snaps into place.

7. Turn the unit upright and fill the hopper with ground coffee. The coffee dispenser is now ready for use.

OPERA TION OF MCD-7

REPLACING THE HANDLE
RETURN SPRING

Figure 1. View of MCD-7, looking

into drum from beneath.

1. Place a coffee filter or a Brew Basket with filter already inserted. Fit it, into the front opening of the MCD-7.

2. Pulling the handle will dispense the amount of coffee you have selected with the foam insert. If you need to change
the quantity of ground coffee that is dispensed (see FOAM INSERTS INSTALLATION, above) choose a different
size of insert.

With use, the handle return spring occasionally breaks. If this happens, the handle will no longer automatically lift after
pulling down. When this happens, the MCD-7 is still usable by simply by lifting up the handle to the top position after
each dispense stroke. The spring can be replaced. Using the illustrated parts breakdown as a guide will help identify the
parts referred to in these instructions. The index numbers in parentheses ( ) will match those in the parts breakdown.

1. Remove the hopper. The hopper is held in place by a screw (5) and nut (6) on both sides of the upper of hopper.

2. Remove the round black knob (21) on the handle. Unthread it , twisting counterclockwise.

3. Remove the bottom screw (9) on the side plate (don't lose the arm stop (7) that it screws into). Also, on the side
plate (8), remove the top screw and the other stop (7) that it is threaded into. Take off the side plate.

4. The next step is to remove the drum and shaft assembly (10). To do this, lay the unit on it's side with the handle
pointing up. Grab the handle (20) with your right hand. Reach inside the MCD-7 and push against the opposite wall
with the flat of your left hand while with your right hand you pull up on the handle (figure 3.). The walls are flexible
enough so that with a little tugging you can dislodge the shaft from the hole in the left side of the wall.

Figure 2. View placing foam inserts

into drum.

5. Once free, pull the handle through the hole on the right side of the MCD-7 (fig 4.) and lift out the drum and shaft.

6. To get off the broken return spring (17), you will have to separate the handle from the plastic drum. The easiest way
is to clamp the metal handle in a vise, grab the drum with both hands; then just yank off the drum with a firm tug.
