Figure 4: Main components of the machine
The machine represented on the Fig.4 (floss pan with mesh screen
and clips are not shown): 1 – Lower rubber leg; 2 – Housing; 3 – Trans-
portation handle; 4 – Chassis; 5 – Transport fastening nuts; 6 – Upper
rubber leg; 7 – Spinning head with heating coil; 8 – Tabs; 9 – Brush
units; 10 – Spring loaded supports; 11 – Main power switch; 12 –
Voltmeter; 13 – Adjustment knob; 14 – Heating switch.
Main power switch (11) turns on the motor, and allows to to turn
the heating. Heating switch (14) turns the heating on. Voltmeter (12)
reads the voltage applied to the heating coil. The more the voltage,
the more power delivered to the spinning head. Adjustment knob (13)
is used to adjust the voltage applied to the heating coil. The spin-
ning head (7) rotates with the sugar mix inside where the heating coil
warms the sugar up to its flow point 120–140°C (250–285°F). Due
to centrifugal force, the melted sugar escapes through holes in the
sidewall of the spinning head (7), where it instantly cools and crys-
tallizes turning into candy floss. Two tabs (8) on the spinning head
causes airflow that pushes candy floss to the pan’s sidewalls (see
Fig.2), where an operator collects cotton candy with a stick.

4 Intended use
CAUTION
•DO NOT TURN ON until transport fastening nuts are
FULLY RAISED. Otherwise it may cause excessive vi-
bration during whole machine operation, and lead
to machine failure.
•Vibration of the spring mounted chassis during spin-
ning head acceleration and deceleration IS NOR-
MAL.
4.1 Important tips
1. Use ONLY 100% pure granulated sugar (beet or cane).
2. DO NOT USE sugar powder, sugar with added starch, dextrose,
corn syrup and so on. Doing so will lead to poor quality floss
and/or quick clogging of the spinning head.
3. To make colored and flavored cotton candy use flavoring mix
(Floss Art, for example), or ready to use flossugar.
4. DO NOT USE excessive flavoring mix! Doing so will:
•increase the cost of production;
•make the product tastes bitter;
•lead to spinning head’s sidewall clogging;
•lead to excessive carbon build-up on the heating coil.
HINT: if you want deeper color, sprinkle the flossugar mixture
with water (1 tablespoon of water per 2kg/5lbs of sugar) and
mix well before put in the machine.
10

4.2 Tabs adjustment
The spinning head has two leather tabs (see Fig.5). Twist each tab so
as its edge becomes parallel to the sidewall cut-outs (dashed line on
the Fig.5). Twisted tabs act as an impeller that creates airflow that
throws the floss to the sidewalls of the floss pan.
Figure 5: Tabs adjustment
4.3 Starting up
1. BEFORE plugging machine in the outlet receptacle, MAKE SURE
both switches (pos.11 and pos.14 Fig.4) are in OFF position.
2. Add flossugar into the spinning head, approximately 3/4 full.
3. Quickly rotate the head manually to distribute the sugar evenly.
4. You will need sticks, rods or cones to spin inside the plastic pan
to collect the cotton floss as it is produced. These can be made
of wood, paper or plastic. Wood sticks and plastic straws should
be soaked in water first in order to create better adhesion for the
floss.
5. Turn the main power switch (pos.11 Fig.4) ON, and the spinning
head will begin to rotate.
6. Turn the heater switch (pos.14 Fig.4) ON.
7. Use the knob (pos.13 Fig.4) to adjust voltage on voltmeter (pos.12
Fig.4) to 150-160 V1.
1When setting up at a new location, the power level must be adjusted according to
the environmental conditions. If cotton candy comes out too slow, increase the voltage
slightly. Alternatively, decreasing voltage will slow production. When you change loca-
tions or if the temperature or humidity changes later in the day (if working outdoors)
then you may need to make additional adjustments.
11

8. Depending on conditions, it will take about one minute to warm
up the head to operating temperature. You will usually smell
the candy aroma between 10 to 15 seconds before production
begins.2
4.4 Making cotton candy
•Get a stick and put it into the pan and start to collect the cotton
floss onto the stick.
•Pull out the stick out of the pan, spinning the stick with hands
at the same time, pulling the floss out of the pan.
•Keep winding. Once there’s enough serving on the stick, tear
the floss flow. That’s it!
4.5 Shutting down
•Turn the heating switch (pos.14 Fig.4) OFF.
•Capture remaining cotton candy as the head cools down.
•Let the head spin for 5-7 minutes to cool down before turning
o the main power switch.
•Turn the main power switch (pos.11 Fig.4) OFF.
Once the head is cooled down and motor is stopped, cover the head
with a paper or plastic bag to protect the flossugar from dust, debris
and insects. The machine and Floss Pan should be wiped down with
a damp cloth to remove excess flossugar as needed.
If you are shutting down for longer than one day, then you should
perform a complete cleaning of the spinning head as described in
the Cleaning and maintenance section below. Do not leave unused
flossugar in the spinning head for more than a day or two as it can
harden/caramelize and aect the balance of the head during future
sessions, which could ultimately result in failure of the machine.
During transportation always secure the chassis using the trans-
portation fastening nuts. This will prevent possible damage of the
machine and prolong its life.
2When this is the very first time of using the new machine, or the sidewall was re-
cently cleaned, the floss might be rough and sti. As little amount of floss built up on
the sidewall, the output product becomes more soft.

5 Cleaning and maintenance
DANGER
•Electric shock hazard! DO NOT use excessive water
or water jet to clean the machine. DO NOT spill wa-
ter or other liquids on electric parts of the machine,
including housing.
•ALWAYS unplug the machine before cleaning.
•ALWAYS keep power cord and plug o the floor and
moisture.
•DO NOT IMMERSE heating coil leads in water.
WARNING
•WAIT until spinning head is cooled down before ser-
vicing.
WARNING
•Use food-grade cleaners ONLY.
•DO NOT USE aggressive cleaners, or sharp items, or
abrasives for cleaning.
The purpose of technical maintenance is to keep the unit operable
during the entire service life.
Recommended schedule
Depending on how intensively machine used, and the supplies, it might
require more frequent cleaning.
Routine cleaning once a day
Spinning head cleaning twice a month
Brush unit maintenance every 6 months
13

5.1 Routine cleaning
1. Unplug the machine from the mains.
2. Take out the mesh screen and clips from the floss pan. Rinse the
screen and clips with warm water to remove residual sugar and
floss. Let it dry.
3. Take the floss pan, rinse it with warm water to remove residual
sugar and floss. Wipe dry immediately.
4. Remove residues of sugar from outer surfaces of the machine
with a clean soft damp cloth. Wipe dry immediately.
5.2 Spinning head cleaning
During long-term operation, the heating element and sidewall steel
mesh might become clogged with sugar and carbon deposits. This
may significantly reduce both productivity and the quality of the cot-
ton candy produced.
1. Unplug the power cord, remove the floss pan.
2. Remove the four screws (pos.2 Fig.6) holding the spinning head
cover (pos.1 Fig.6), and remove the cover. If the cover is ‘glued’
to the sidewall, gently tap with the screwdriver handle in or-
der to loosen the parts. Note that the cover is made from alu-
minum and can be damaged by excessive tightening the screws,
by throwing, or by heavy impact.

8. Rinse the sidewall and the heating coil with hot water to remove
residual flossugar. DO NOT IMMERSE the heating coil leads
(pos.6 Fig.8) in water!
9. Take apart the heating coil and the sidewall. Rinse the sidewall
properly with the hot water. Wipe dry immediately.
15

10. Remove carbon build-ups from the heating coil. AVOID exces-
sive mechanical impact.
11. Assemble in the reverse order. NOTE: the heating coil leads
(pos.6 Fig.8) MUST BE placed opposite to the balancing pole
(pos.2 Fig.8). It is important to make sure while putting coil
back in the sidewall that upper point of the coil is 4 to 5 mm
lower than the upper edge of the sidewall (pos.2 Fig.9). If coil
is placed evenly with the sidewall edge (pos.1 Fig.9), it might
cause machine to “spit” liquid sugar.
12
Figure 9: Coil in the sidewall
12. Plug the machine in, turn the spinning on. Let it spin for 30-60
seconds, to remove residual water. Turn the machine o, unplug
the cord.
5.3 Brush unit maintenance
As with most electrical motors, the machine utilizes brushes and slip
rings which are subject to wear and require inspection, maintenance
and eventual replacement.
1. Remove two screws that hold the hatch (pos.1 Fig.10); remove
the hatch.
2. Inspect the slip rings (pos.2 Fig.10) for bumps and color changes.
The rings should fit closely to insulators and should not show
excessive wear.
3. Slip rings are made of high-grade brass and will last years if
properly serviced. If the slip rings are excessively worn or are
covered with bumps, they need to be replaced by qualified ser-
vice sta.
4. Remove all dust, debris and tarnish from the slip rings.

Figure 10: Brush unit maintenance
5. Remove two screws to open the brush unit (pos.3 Fig.10)
6. Take out two carbon electrodes (pos.4 Fig.10).
7. If electrodes are significantly worn out, or broken, the brush unit
should be replaced.
8. Repeat for the other brush unit.
9. IMPORTANT: After installing new brushes, allow the motor to
run for 15 minutes before turning on the heating element. This
will allow the brushes to conform to the slip rings, avoiding the
potential for arcing under load.
5.4 Conservation
If the unit is not used for a prolonged period of time, then the routine
maintenance must be performed before it is placed back into service.

•Check capacitor. Replace fault capacitor.
Machine doesn’t produce cotton candy
•Ensure heating switch is in ON position.
•Increase the voltage supplied to the heating element with the
adjustment knob.
•Check heating element. Replace fault heating element.
•Check brush units. Replace fault brush unit(s).
•Check power regulator VS, variable resistor RP. Replace fault
component(s).
•Check the internal wiring for open circuit. Fix open circuit.
Excessive vibration during operation
•FULLY RAISE all four transport fastening nuts.
•Ensure heating coil leads placed opposite to the balancing pole,
(see pos.2 and 6 on Fig.8).
•Distribute sugar inside the spinning head evenly.
18

•Check spinning head to see if there are foreign objects inside
the head. Remove if any.
Floss comes out as flakes, or smoke coming out from the
head
•DO NOT use sugar with added starch or similar. Ensure all rec-
ommendation regarding sugar used are met, see Important tips
section above.
•Decrease voltage supplied to the heating element with the ad-
justment knob.
•Clean sidewall and heating coil.
•Check power regulator VS, variable resistor RP. Replace fault
component(s).
Machine “spits” liquid sugar
•Ensure the coil is positioned below the upper edge of the side-
wall, see Fig.9.
Low productivity
•Increase voltage supplied to heating element by adjustment knob.
•Clean spinning head.
•Check voltage in the wall outlet. Low voltage causes low pro-
ductivity.
Cotton candy melts fast
•Sugar absorbs moisture easily. High relative humidity of am-
bient air makes cotton candy melts fast. Choose the working
locations with lower relative humidity levels.
Circuit breaker trips
•A short circuit in the machine, locate and fix.
