Important Attentions Before Use
1. The materials ready for grinding must be dry enough.
Wet, moisture or oil materials are not suitable to be ground into powder.
Dry the materials as much as possible before grinding, and then grind it
when it is completely cool.
2. Recommend grinding capacity one time：
Do not fill the grinding tank to full otherwise it will cause overload.
The material you gonna to grind one time must cover the long blade
in the middle and no more than 2/3 of the tank. Because this machine
needs a space to complete the cycle of the blades and the material to be
grind.
3. Recommend use time: no more than 3 minutes.
Even if grinding stone, it only takes 2 minutes, so don't use it for too long.
It takes 5-10 minutes to rest after every 3 minutes of work. If you
grinding some hard items, there should has a interval which is to prevent
bearing overheating, damage to the motor.
* General grains only need 30s to be ground into powder. If you are
not satisfied with the grinding effect, you can sieve out the coarse
particles with a mesh screen and grind it again for finer powder.

4. Check the blade and the nut is loose or not before grinding. To
ensure safety, the nut should be tightened before grinding. After
long-term use, blades and carbon brushes need to be replaced if they
are worn.
5. Don't clean the grinding bin with the water directly. Keep water
away the grinding tank and use dried rag or brush to clean the machine.
6. The motor of the grinder is the brush motor, the sparks and the
odor is normal when the first several uses. The sparks and the brush
frictional odor will disappear after you use the machine some times later.
You can Grind some rice or tea leaves first for several times to
eliminate the odor.
7. Special Reminder:
*150g grinder machine are not suitable for grinding panax notoginseng,
pearls and other tough items.
*When using 300g machine to grind panax notoginseng, pearls and
other tough items, they should be sliced to small pieces first.
*The over 300g capacity of the machine is more recommended to
choose for grinding large and hard items.

Operating Instruction
1. Operations Guide:
1. Open the upper cover and put the dried material inside;
2. Close the upper cover tightly; (Please make sure the lid is rotated to
the end and locked tightly on the top.)
3. Plug in and turn on the timer switch, then turn on the switch for
grinding(Rolling sound will be heard );
4. Turn off the switch; (When you hear the sound rolling evenly, the
material has been grinded into powder, then you can turn off the switch)
5. Disconnect power supply before opening
6. Open the upper cover and brush the powder out
2. Grinding Cautions：
It is not suitable for grinding something which is wet, fresh, soft ,strong
toughness such as meat, fruits, vegetables, etc.
1) To grind something more easily when the material is high-hardness,
big in size, or has the strong fiber, you need to cut them into small pieces,
for example, to grind the notoginseng better, you need to cut them into
small pieces.
2) For the oily items , such as peanuts, sesame, walnut, etc. You should
first dry, or fried-dry them before grinding. If you just grind a small
amount , usually grind for 15 seconds , then stop for 10 seconds. If you
need a better grinding effect, you could do this for several times.
Notice: When you first use the machine,you’d better clean the machine
with cloth moistened with vinegar or medical alcohol,and then put some
rice and dried tea leaves into grinding bin,grind them for 30~50
seconds,then pour the power out, clean the grinding bin.

3. Common Questions：
* Why the grinder cannot be started？
First check whether the indicator light is on.
If the indicator light is not on, check whether the power supply is plugged
in tightly and whether the power cord is damaged (you can replace the
power cord of other household appliances).
If the indicator light is on, the possible reason is that the induction switch
in the two buckles of the cover is not triggered yet.
Please make sure the lid is rotated to the end
and locked tightly on the top.
Please scan to watch the video of how to close the lid.

Please kindly try to adjust the screws on the two sides.

* What to do if the grinder suddenly stops working?
If the grinder stopped working, the reason may be that the blades bottom
is stuck or the overload protector function works because of overload and
the carbon brush is worn.
It's easy to solve this problem.
You just need clean the blades bottom or re-install the carbon brush
on the both sides again and then press the overload protector button
again, then the grinder could work well,
Please see the overload protector and carbon brush in the attached
pictures, please check that.

*Why the motor becomes hot ？
It is normal for the grinding machine to be slightly heat, because
the working principle of the machine is to pulverize the material
into powder through the high-speed rotation of the blades. The
whole process is carried out in the closed grinding bin, which
will generate heat and cause the machine to heat up.
There may be several reasons for machine overheat:
1）The materials ground is wet, moisture.
Please Dry the materials as much as possible before grinding, and then
grind it when it is completely cool.
2）Grinding time is too long.
The machine must take 5-10 minutes to rest after every 3
minutes of work. If you grinding some hard items, there should
has a interval which is to prevent bearing overheating, damage
to the motor.
3) Put too much materials into the grinding bin one time.
The material you gonna to grind one time must cover the long
blade in the middle and no more than 2/3 of the tank. Because
this machine needs a space to complete the cycle of the blades
and the material to be grind.
If the machine overheat makes ono-working, you can also solve
it by re-installing the carbon brushes on the both sides again and
then pressing the overload protector button again, then the
grinder could work well.

Grinding Suggestions for Common Materials
1. When using for the first time, please grind the rice and dry tea leaves
first about 30 seconds by the machine, which can clean the grinding bin
and remove odor, stains.
2. For Grinding Spices (such as: Chili, Pepper, Fennel, Aniseed etc.)
The grinding work can usually be completed in 20 seconds, do not take
too long.
3. For Grinding Whole Grains ( such as soybeans, rice, millet, black
rice, corn, etc.)
It is recommended to rotate the timing switch to about 30 seconds
grinding time. If the powder is not fine enough, you can repeat the
grinding.

13
4. For Grinding Common Herbs, ( such as Ginseng, Astragalus, Ejiao,
Gastrodia, etc.)
It is recommended to set the grinding time to 1-2 minutes.
5. For Grinding Oily Materials (such as walnuts, sesame, peanuts,
etc)
Before grinding, it is better to bake the oily materials in microwave (or
dry in the sun ,or bake). After the material is completely cool, then you
can grind them,more dried more better.
Don’t grind for a long time. Use interval grinding method, that is Pause
about 5 seconds after every 10 seconds working and check the grinding
effect until you are satisfied.
Continuous working will make the machine be easy to overheat, damage
the motor and the effect is not good.

14
6. For Grinding Super-hard Materials (such as pearls, tortoise
shells, Tianqi, Panax notoginseng, etc.)
It is recommended to crush the materials into small pieces before putting
into the machine for grinding. And during grinding, pause about 10
seconds after every 1 minute working. The grinding job can be completed
in 2-3 minutes.
7. For Grinding Fibrous Materials (such as Dendrobium，
Ganoderma lucidum, etc.)
Because this type of material itself has a fibrous structure, it cannot be
ground into powder state, and usually it will be ground into floc.
It is recommended to use interval grinding method.
Note: Different materials have different properties, and the required
grinding time is different, which needs to be adjusted in actual operation.

15
Instructions of Air Overload Protector
When blades are jammed in grinding bin, it will happen that air
overload protector pop up and the machine automatically cut off the
power supply.
If this situation happens, turn off the power and check the grinding
bin. You just need clean the blades bottom and press the
overload protector button again, then the grinder could work
well.

clean it with dry cloth.
After using blades for a long time ,you can remove them and clean them
with water.(The blades of new grinder must be very tight,you need to use
for a long time,then blades can be removed.)
Firstly, loosen the nut by using a pincer and remove the blade.
Secondly, wipe the grinding bin with a dry rag after removal of the
