4. Wait for the grinder motor to stop before removing the brew cone.
OPERATING INSTR UCTIONS - ISLG
Factory settings: SMALL grind button, set for 5 seconds (1.3 oz). LARGE grind
button, set at 15 seconds (3.8 oz). ISLG -13, has additional MEDIUM button set
for 10 seconds.
1. Place the brew cone into the rails on the grinder. Press one of the grind
buttons on the switch panel. Ground coffee will start to fill the brew cone.
2. When the grinder motor stops, remove the brew cone and slide it into the rails
on the brewer.
3. Press the brew switch that displays the blinking indicator light. This starts a brew cycle.
To cancel a brew cycle, press the ON/OFF switch on the brewer. Brew cycles in process will be
cancelled.
ADJUSTING THE GRINDS
Refer to illustration page 2.
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 finer 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.
*This adjustment may change the amount of ground coffee dispensed.

PROGRAMMING THE ISLG
NOTE:NOTE:
NOTE: Before reprogramming the ISLG, the factory timer settings may be all you need.
NOTE:NOTE:
The factory settings: The SMALL grind button is set for 5 seconds (1.3 oz). The LARGE grind button is set at 15 seconds (3.8
oz). On the ISLG -13, there is an additional MEDIUM button that is set for 10 seconds.
1. Open timer cover (behind hopper). Find timer and move the switch from RUN to PROGRAM.
2. Use a stopwatch (recommended) or sweep second hand to time your batches. It is usually quicker to optimize the SMALL
button first. You will then have a more accurate start point for optimizing the other grind button[s].
3. Place an empty filter and cone under the grinder. With your stopwatch ready, press and
button for the desired number of seconds. Weigh the grounds. Record the time and weight. If you are below your target
weight, you can reinsert the filter and add time in small increments by pressing and holding the same button.
Weigh again and add time as desired to reach your target weight. When you are satisfied with the amount, switch the timer
back to RUN and re-grind to test the time and weight. Write down the results.
4. When the time/weight programming is completed, install the front cover.
