OPERATING INSTRUCTIONS - SLG

The SLG grinder is adjusted at the factory to grind 2 - 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

Refer to illustration, page 2. This adjustment may change the amount of ground coffee dispensed.

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

2. Open housing cover to locate adjustment screw (8) and lock nut (7). Loosen lock
nut.

3. Run motor during adjustment. Turning adjustment screw clockwise will result in a
ner grind (if, while turning, 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. Run some coffee beans through the machine to check the grind 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 grind cap (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.
