Page 3: Introduction
What one receives may vary depending upon the supplier. The M3 roaster comes in a standard package from the factory or the Quest dealer in the United States, Coffee Shrub. At the time of writing, the M6 roaster sold by Coffee Shrub comes complete with a rectangular bean collection tray that will fit into the cooling chamber (but which is too small to handle a full load) and an external fan-driven cooler (which is more than adequate for a full load). -

Then lower the plate onto the four fixing points, and insert the filter basket into the hole. Screw a thermometer or thermocouple into the M6 tapped port on the front panel below the trier port. If using the supplied analogue thermometer, secure it so that the dial is oriented correctly using the locknut provided. -
Page 5: Controls And Basic Settings
Controls and Basic Settings Power Switch: The power switch is the upper-right knob on the control panel. It turns stiffly, as it is a mechanical timer. The on position is fully clockwise, and the off position is fully anticlockwise. Its primary function is a safety switch;... -
Page 6: Basic Operation
Basic Operation Preheat: Preheat the roaster to the desired temperature before use. To do this, close all the doors, set the blower to the lowest setting, set the heater control to maximum, and set the timer switch to the 10 o’clock position. -

300 grams or less. The round bin supplied with the M6 and its optional fan/cooler unit will easily cool more than 500 grams (about a pound) of beans. Be careful with the heater control when the collector bin is in the cooling chamber. Inserting the bin into the chamber stops all air from passing through the roasting chamber, even when the blower runs at high speed. - Page 8 Cleaning After Roasting After roasting, turn the blower to the highest blower level, with the heat off, for about one minute to suck any remaining chaff from the drum. While running the blower, open the bean entrance cover and sweep any powder into the air pipe; it will move into the cooling chamber. Sweep all the chaff and dust in the cooling chamber into the filter cup, dump the cup and reinsert it.

● Unscrew the single screw in the middle of the bearing (some are hex-head, some are Philips- head). ● Support the air pipe to prevent it from falling, as it is not firmly affixed. ● Remove the front plate, then the drum. To reinstall: ●... - Page 10 One can roast coffee beans to many different levels, each with its characteristics. Generally, as coffee roasts: ● Weight decreases (12-20% for drinkable roasts), and volume increases (the degree of expansion varies by type of bean). ● The bean’s inherent flavours diminish and the flavours imparted by roasting increase. ●...

Page 11: First Operation (Seasoning)
This profile is suitable for first-time roasters. Because the roaster is loaded to capacity and starts at a relatively low charge temperature, it is unlikely to overheat and scorch the beans. Prepare 500-550 grams of beans (M6), 250-300 grams (M3). 1 Preheat the roaster until it idles at 150º Celsius. - Page 12 By limiting the heater current, one can roast smaller batches using these two profiles. Roasting smaller batches makes the roaster more responsive. For example, in the M6, a 350-gram roast can be done by setting the heater current to about 9-Amperes (120-volt model).

Drop Engineering There are currently two main models, the M3s and the M6. The M6 is the larger of the two, with a longer roasting chamber and more powerful heaters. Otherwise, they are nearly identical. The current roasters differ from the original mainly because they have drums with perforated backplates. - Page 14 In the M3s and the M6, the same fan, air tube, and bean chute create suction in the drum. From this point on, the flow is different. There is no air hole at the back of the roaster. There are two ~3mm longitudinal slots underneath the roaster below the heaters, running the drum’s entire length.

1615 1340 *The M6 is 7 cm longer than the M3, all in the roasting chamber; the other two dimensions are identical. The M6 is taller only because the base is taller. Depth measurement does not include the handle for the roasting chamber door. -

On an M6 roaster, push the probe completely in, which will position it correctly. The heaters on some roasters are mounted low in the roasting chamber; therefore, you can use either of the two upper screw holes.
- Page 18 most responsive of the three temperature readings (BT, ET, MET). Thus, it is an excellent choice to monitor the effects of heater and blower control changes. Measuring Devices Energy Monitors: Some owners like to see the power displayed in Watts, rather than amperes, as indicated by the current meter, as this is more precise.

- Page 20 For this step, you must read the QSG in detail. First, decide if you will use buttons or sliders to record gas (heat) changes. Decide which boxes you want to check, including Auto Drop and Auto Charge. Some people use Auto Drop but not Charge, which helps to focus on the roast’s start.
- Page 21 The latest Quests have neither intake hole nor tubes. Instead, there are two slits of about 3 mm width, one on each side, low down on the roaster. These slits run the entire length of the outer case. At least some of the roasters with a lower chaff drawer have this feature, the slits being on either side of the drawer assembly.
- Page 22 A increase in voltage occurs simply by keeping the extension cord as short as possible and by shortening the supplied power cord, especially on the M6 because of its bigger heaters.
- Page 23 Automating the Quest Because the Quest roasters are entirely manually operated, with no special hardware and no firmware, they lend themselves easily to automation. While most Quest buyers select them because they are simple, manual roasters, several owners have already automated theirs. It is not our intention to do a deep dive into automating the Quest.
