Alterations Service & Accessories
●Do not modify the R1.
●Do not disassemble R1. Only authorized service personnel are allowed to repair
malfunctions.
●Unless recommended by Aillio, accessories must not change the operation of the
coffee roaster or interfere with normal operation.
●Do not operate the Bullet R1 if not fully assembled. This includes connecting the
chaff collector.
●Do not operate the coffee roaster if it is damaged or you suspect a malfunction.
●Do not attempt to service the roaster yourself. The use of accessory attachments
other than those supplied or recommended by the manufacturer may cause
hazards and can void your warranty.
Electrical
●To avoid electric shock, do not operate the roaster in a wet environment or near
water. Any cleaning should be with a moist or dry cloth and should only be
performed when the roaster is cooled down and with the power cord
disconnected. Please see the cleaning section.
●The power cord and USB cord must be arranged in such a way that they will not
be tripped over, or able to pull the roaster off the table. Keep the cords away
from the front part of the roaster, which may get very hot and can melt the wire.
●The Bullet needs a dedicated electrical circuit with ground (earth). Do not plug
other appliances into this circuit.
●If an extension cord is needed, please make sure it meets the minimum
requirements of power rating and is fully grounded (earthed). Do not connect
other appliances to the extension cord.
●Always disconnect the power cord after the roaster has cooled down.
Mechanical
●Never touch moving parts, and do not place hands or fingers inside the drum
while the coffee roaster is connected to the mains.
●The coffee roaster is heavy, and care should be taken when moving the roaster.
Only move the roaster when it is completely cooled down. Do not lift the coffee
roaster by the legs, door handle or cords.
Roasting
●When the coffee beans are dropped into the cooling tray, they are extremely
hot, and should not be touched until they have cooled completely.
●The operating environment should be clean and free from dust and sand.
●The R1 is only intended for roasting coffee beans. Roasting other foods will void
the warranty.
www.aillio.com 5
●After roasting has finished, the R1 will enter a cool down mode which will cool
the drum. DO NOT disconnect the power until this cooling cycle has finished or
you risk damaging the electronics.
●The Chaff Collector should ALWAYS BE INSTALLED while roasting and needs to
be emptied and the filter cleaned after each roast.
●After roasting 20Kg and while the roaster is cool, remove chaff under the drum.
Refer to cleaning instructions.
Venting
During roasting, smoke is produced which should be vented to the outside or to a
smoke suppression filter. If roasting in the kitchen, a powerful range hood can be used.
Place the R1’s air outlet directly underneath the range hood.
For fixed installations a pipe can be connected to the R1 to vent the smoke outside or to
a filter. It is recommended to use a metal pipe or flexible hose with a diameter of 75mm
(3 inches) or larger. If the pipe or hose is directly attached with an adapter, the length
of the pipe / hose should not be longer than 3m. If the pipe / hose is longer, a suction
fan should be placed at the end of the pipe / hose to ensure adequate airflow. The
suction fan can affect the performance of the R1 by increasing the airflow, thus
potentially removing too much heat.

Unpacking and preparing the R1
Mechanical Check
After receiving the R1, please inspect the packaging for any damage. If you are in
doubt, please contact the shipping company, and document the damage.
After shipping or moving the roaster, there are a few things that should be checked
before roasting can begin. The purpose of this check is to adjust drum to front plate
clearance, pulley clearance, and belt tension.
●Make sure the Drum is in the most forward position as described in
“Maintenance”
●Take off the chaff collector. Make sure the pulley set-screws are snug as
described in “Maintenance”
●Plug in the roaster. Press PRS three times to enter Roast Mode and then set
Heating to P0. Listen for any obvious metal against metal scraping sounds.
●If you see rust on the drum, do not be alarmed. It is normal for an unseasoned
drum to oxidize and this will disappear during seasoning.
www.aillio.com 11
Seasoning the Drum
Before you can roast any coffee for consumption, you will need to do a minimum of 3
roasts to season the drum. The oils from the coffee will help seal the steel drum so that
it will not rust and it will create a more smooth surface inside the drum. The drum may
not be fully seasoned until 5 to 10 roasts have been completed but after 3 seasoning
roasts you can drink the coffee you roast. Each seasoning roast should be performed
with 400-500g of green beans. (There is no need to use your 90+ coffees at this
point:-) )
1. For newer models (V1.5 / V2.0) with the IBTS sensor the preheat should be set to
230°C. For the older model V1 the roaster should be preheated to 160°C (320°F).
2. Press PRS to start preheating
3. When the preheat temperature has stabilized at 230°C (160°C for the old model
V1), press PRS and the control board will start to flash.
4. Add 400-500 g of beans, and this will start the roast.
5. Once the roasting has started, make sure the drum speed is set to D9 for fastest
rotation by pressing F2 and using the up and down buttons to set D9.
6. Roast the coffee all the way until after the end of second crack when the coffee
is dark and shiny. Instead of dumping the beans into the cooling tray, you can
turn off the induction power at the end of the roast, and run the fans at FA while
keeping the beans in the drum for a few minutes. Then open the door and dump
the beans.
7. Repeat this procedure at least 3 times
These beans are not for consumption! Trust us! Machine oil doesn’t taste good!
It is very important to not heat the R1 to a higher preheat temperature than 230°C
(160°C /(320°F for the old model V1) as the IR sensor will give a different measurement
for non-seasoned drums.
IMPORTANT NOTICE
●For R1 V1 it is important to clean the IR window on the inside of the front plate
after seasoning. For V1.5 and V2.0 there is no IR glass to clean. See the
maintenance section to learn how to do this.
●Drum speed should be set to D9 for the first 10 roasts. This is to prevent beans
getting stuck and potentially pushing the door open. After about 10 roasts, the
surface should have less friction and the drum speed can be lowered.

Operating the Bullet R1
Operating modes
The PRS button controls the different cycles of the roasting process. Pressing this
button will cycle through each roasting step.
Off Mode
The roaster is ready to preheat. The power up
and down buttons will select your preheating
temperature.
If you have already completed a roast, the
drum may rotate in this mode. Cooling fans are
off, but pressing F2 will start the blower to cool
down the R1 if the drum temperature is higher
than 80°C (176°F).
Preheating Mode
The roaster will start preheating to your
desired setpoint. The display will show PH
while heating to the setpoint and PH A once it
begins to keep a steady temperature. Once ready, the R1 will automatically go to Load
Mode.
Charge Mode
The R1 is ready to roast and you should pour the green beans into the roaster through
the funnel. Once loaded, the R1 will automatically go to Roast Mode. While in Charge
Mode, the R1 display will blink and it will say “Charge”.

Roasting coffee
Preparing a roast
1. Place the R1 on a suitable table and connect the
cooling tray cable to the connector on the right
side of the R1
2. If the R1 has been moved around, make sure
the drum is at the most forward position by
opening the door and pulling the drum forward
toward the front plate.
3. Connect the power cord and turn on the power.
4. Ensure that the bean chute lid is in place.
5. Once the R1 is ready, it will indicate this by the
display showing OFF (Fig. 1).
Preheating the R1
1. Set your desired preheat temperature by using
the H/C buttons (Fig. 3). Refer to the table on
page 21 for recommended settings.
2. Press the PRS button, which will start the
preheating process (Fig. 4).
The R1 will now preheat the drum to the temperature
you have set. Once the temperature has been reached,
it will maintain this temperature until beans have been
charged, as detected by the bean temperature
derivative (ROR) being below -20°C (54°F)
Notice
Under some circumstances the R1 will not
automatically enter Charge Mode. This can be caused
by a low ambient temperature, excessive airflow
around the R1, external exhaust flow which increases
airflow etc. You can manually press the PRS to enter
Charge mode in these cases. If the R1 has not entered
Charge Mode after a period of 35 minutes, it is
necessary to manually press the PRS button to enter
the Charge mode.
www.aillio.com 17
Charging Beans
1. When the display starts flashing, the R1 is
ready to start roasting (Fig.5).
2. Remove the bean chute plug and insert the
funnel into the chute. The lip of the funnel
should face backwards to cover the exhaust
pipe.
3. Load all of the green beans into the R1 at the
same time.
4. The R1 will automatically detect that the
beans have been loaded and will change to
Roast Mode and start the timer.
5. After all the beans are loaded, pull out the
funnel and replace the bean chute plug.
6. Be careful not to press the PRS button until
you want to finish the roast.
Notice
If you are roasting very small batches, the R1 might
not be able to detect that the beans have been
loaded. In this case, you can start the timer
manually by pressing the PRS button.
Roasting
1. While roasting, you can control the heating,
exhaust fan, and drum RPM. To change the
heating, use the H/C buttons (Fig. 6, left). To
control the exhaust fan, use the FAN buttons
(Fig. 6, right). Please note that fan speeds
6-9 are strong enough to make the
temperature drop dramatically and should be
used with care. The FAN buttons also control
drum RPM. To change between the two, use
the F2 button. Drum RPM is marked by a “d”,
and fan speed with an “F” (Fig 8).
2. The DT display can show the rate at which
the bean temperature is going up or down.
You can toggle this by pressing button B
while roasting. The display value is °C/min
(°F/min). Some roasters also refer to this as
rate of rise (ROR) (Fig. 7).
3. The FAN button controls both exhaust fan
and drum RPM. To change between the two,
use the F2 button. Drum RPM is marked with
a “d”, and fan speed with “F” (Fig. 8).
www.aillio.com 18
4. Bullets with the IBTS (V1.5 & V2.0) will by
default show the IBTS temperature as the
Bean Temp. The X-LED light above the A
button will be ON when the temperature is
from the IBTS and OFF when displaying the
bean probe temperature. By pressing the A
button you can toggle between the bean
probe and the IBTS.
SAFETY
If no adjustments have been made and no buttons
pressed on the control panel for two minutes, the
R1 will sound a warning. Firmware v. 386 and up
will show the message A-02 in the clock display.
Press any button to let the R1 know that you are
present and to stop the alarm. If no button is
pressed within one minute after the warning
begins, the power will be set to P0, and the exhaust fan set to F9 to stop the roasting.
The safety feature only activates after the bean temperature is above 160°C (320°F)
Drum speed
The drum speed can influence the bean temperature reading. If roasting smaller
batches, a higher RPM can sometimes give a more precise reading.
Cooling the beans
1. When you want to finish roasting, press the PRS button and at the same time lift
the door handle to allow the beans to exit the drum. It is not necessary to open
the door fully.
2. During the bean cooling you may press the F2 button to show the value C9 which
is the speed of the cooling tray fan. You can change the speed of the fan by
pressing the fan buttons - up/down.
3. After the beans have been cooled, press the PRS button to enter the shut down
mode. In this mode the roaster will cool down until the drum has reached 80°C
(176°F), after which it will enter Off mode.
4. Instead of shutting down, you may choose to continue with back to back roast.
To do this, press the F1 button while in Cooling mode. This will take you back to
the off mode, but with the cooling tray still running (the clock display will show
bAC. After setting the preheat temperature, press PRS to begin another preheat
and roast.
