III. OPERATION INSTRUCTION
1. It should keep at least 1 cm of the distance between the tip of the
stirring shaft and the inside bottom of the vessel. Don’t let the
homogenizer head touch to the bottom of the vessel.
2. Rotate the speed adjuster knob toward the left end; then plug in the
power cord and switch the machine on.
3. Press “START” button and adjust to the desired speed; press “STOP”
button to stop the stirring.
4. For avoid idle running, the flowing speed of the liquid should be
available to the stirring speed of the machine.
5. After a long time use, if the motor temperature over 75 degree C, the
over-heat protection device will start and stop the motor running.
When the temperature come down (about 30 mins later), the machine
can re-start to run. If the situation repeats to happen, User should
reduce the loading on the machine. Don’t overload the machine;
otherwise its motor will be damaged possibly.
6. Using the homogenizer heads alternately is available. Just need
release the fixing screw under the homogenizer head, the
homogenizer head can be taken off easily.
7. The homogenizer head is available to be dismantled, so users can
clean it after the operation.

IV. CAUTION
1. Avoid using this machine with other instruments in one and same
power supply.
2.
Serious or often overloaded use should be possible to cause the
fast carbon brush consumption as well as the motor damage.
3.
It’s necessary to turn to a low speed for 1~2 hours at least after
changing a new carbon brush, otherwise the motor will be damaged
possibly.
4.
The speed has to match material’s viscosity to avoid head at
empty rotation.
5. After cleaning or changing the homogenizer head, please fix and
screw it tightly.
6. The bad fluid sample is not suitable to be operated by this
instrument
7. The homogenizer head should be fixed at the correct position
carefully, any missing will make the head deformed and jammed
inside.
V. SELF-INSPECTION
When the machine is out of order, please check following possible facts:
1. Fuse burned out or not。
2. Carbon brushes at the both sides of the motor are used out or with the
contact improperly.
3. If carbon brushes are used out, please replace the new ones.
If User did the above self-inspections but still couldn’t delete the failure,
please contact with the distributor for help.
