Chapter IV  Operation
4.1. Operating position
4.2. Preparation before Switching on: the follow steps must be taken especially before the first starting
4.2.1 Machine must be installed and connected according to the regulation.
4.2.2 Check whether the bolts and nuts are tightened up and whether the tension and parallelism of V-belt are proper.
4.2.3 Check whether the opening and closing adjustment of feed hopper and pressure door is flexible.
4.2.4 Check is the rotate direction of motor if correct ( faced with feeding port, the correct direction is clockwise).
4.2.5 checking if there is below situation when running without material
a) the temperature of bearings must be lower than 30ºC
b) If there is abnormal noise or vibration
c) If the electric current is normal
d) Check if there is vibration at ground, if yes, leveling each foot by iron rod.
4.2.6 Adjustment of air volume
      When running, the air suction volume should be about 2000m³/h in order to clean all bran.
4.3 Start and shut down
Start: start the posterior host--------start main machine-------running without material(test run)----------open feeding board--------adjusting flow------adjusting pressure gate
          When working, don't put anything on the machine.
         Shut down: stop posterior host-------close feeding board---------open pressure gate-------shut the power-------open access door-------clean
    4.4 Operation
4.4.1 Adjustment of feeding flow
If test-run is normal, put the pressure lump at the bottom, open the feeding board, fill the whitening chamber with material. When it starts to outletting stabilize the electric current and adjusting the flow, observing the ampere meter. Adjusting the whitening degree according to the rated current.
Notice: the actual current can't over rated current and it can't run full load too long.
4.4.2 Adjustment of whitening degree and broken rate
Usually, whitening degree is in direct proportion to broken rate, high whitening degree then more broken; low then less broken. After start the machine, when current is stable, whitening degree can be changed by adjusting the pressure lump.
Whitening degree also can be changed by adjusting the mobile blade, but this action must be done when the machine stops and the blade can above the screen for 1.5mm at most.

5.1.4. Regularly check the following items

Items	Description	Frequency
Overheating of Main Bearing	Touch the bearing block to check overheating after running for 10 minutes. When overheating detected, remove and check. Replace it if necessary.	Weekly
Abnormal Noise	Run each units separately to exclude abnormal noises before starting.	Anytime
V-belt tightness	Press the belt by hand, if it can be pressed down 20mm, the V-belt tightness is appropriate	Weekly
Sieve Wearing	Usable unless broken or deformed	Weekly
Bran Accumulation inside the machine	Clean interiors	weekly
Bran accumulation in the bran pipe	Clean the bran in the bran pipe	Periodically

Caution Maintenance and examination should be conducted only after the machine stops completely. (The spindle may run further for about 3 minutes after switching off the machine.)
5.2.  Replacement Sequence of easily worn Parts
5.2.1. Procedure of replacing sieve
Unscrew M10 bolt on the mobile deck support,
When exchange new sieve, please remove the grease.
5.2.2 Changing screw and emery roller
a)Open the access door on both sides, take away mobile deck support, remove the sieve.
b)Disassemble the locknut and lock washer.
