a grounded electrical outlet of 120VAC, rated at 15 amps.

OPERATING INSTRUCTIONS - SLG

The SLG grinder is adjusted at the factory to grind 2 to 2.5 ounces of
medium roast coffee.

1. Lift off the clear hopper lid and ll the hopper with whole coffee

beans.

2. Place a new lter into your brew cone. Slide the brew cone into the

brew cone rails on the grinder.

3. Push the START switch on the front panel. The SLG will start to
grind coffee into the brew cone.

4. Wait for the grinder motor to stop before removing the brew cone.

ADJUSTING THE GRINDS

This adjustment may change the volume of ground coffee
output. See Setting the Timer on page 2.

1. Empty the coffee beans from the hopper. Run grinder
to clear grinding burrs of coffee.

2. Open housing cover to locate adjusting screw (1) and
lock nut (2). Loosen lock nut.

3. Run motor during the adjustment. Turning adjusting

screw clockwise will result in a ner grind. If you hear

the grinding burrs starting to touch, immediately, back
off 1/8th turn. Turning counter clockwise will produce a
coarser grind.

4. With a screwdriver holding the adjustment screw in
place, tighten the locknut.

5. Grind some coffee beans to conrm the adjustment.

6. Replace front cover on machine.

CHANGING A BROKEN SHEAR DISK

1. Unplug the power cord.

2. Open the hopper and remove any coffee beans, then open the front cover.

3. On the grind motor assembly, take out the two thumb screws (10) and remove the hous­ing cover (6).

4. Pull out the grinding burr/feed worm assembly (2). The inner half of grinding burrs will
remain within the housing.

5. Separate the shear cap (5) and shear drive (3). The broken shear disk (4) should fall out
from the slot on the drive.

6. Inspect and clean the housing (1) of any coffee or debris. Especially, look for something

that could have caused the shear disk to break.

7. Re-insert the feed worm and grinding burr on the motor shaft.

8. Push the shear drive through the burr/feed worm assembly and align the large slot with tongue on motor shaft.

9. Rotate the burr/feed worm assembly to align the slot with the narrow slot on shear drive.

10. Slip a new shear disk into the slot. Cover with the shear cap. Replace the grind cap and thumb screws.

11. Return power to the unit.

SETTING TIMER

1. Take off timer cover, located behind hopper. Remove the four screws holding the cover in place. The timer is found
inside this cover. Also refer to the illustrated parts diagram on page 3.

2. The timer controls are a high/low switch and a dial with a corresponding scale. The switch allows you to select a
scale on the dial. The outside scale range is ½ second through 15 seconds. The inside scale range is 2 seconds
to 60 seconds.

3. Test a new adjustment by grinding some coffee. When the results are
satisfactory, install timer cover.

NOTE: Use these time settings as a general guide. Actual amounts will vary with the grinding burr setting
and the specic coffee variety you use. After changing the timer, weigh your output, then make adjust-

ments if necessary
