Trouble

Possible cause

Solution

1

leak

slurry

from throat
block

①the nuts of throat block are loose.
②the installation of throat block is incorrect.
③O-gasket of throat block comes off
④O-gasket of throat block is worn-out.

①tighten the nuts
② tighten the two nuts on a
diagonal
③ prevent the O-gasket from
coming off during the throat block
installation.
④replace the parts

the bearing
sleeve

can

not

be

removed.

①do not use the lube.
② do not remove to clean during one-week
cleaning

①use the lube
②clean

3

the stirring
shaft

can

not

be

removed.

①stirring shaft and bearing sleeve are not on
the same level.

①adjust the the position of stirring
shaft and bearing sleeve.

4

abnormal
sound

①lack of slurry in the cylinder
② the machine enter into refrigeration
program when the water is full of water.
③the bearing sleeve is worn-out
④the plastic scrappers are worn-out.
⑤the stirring shaft is broken.
⑥the pipes and plates resonate.
⑦some slurry flow into stirring motor.

①、②read the manual
③~⑤replace the parts
⑥correct the parts
⑦ clear the slurry in the motor or
replace the motor.

5

odors

①scorched belt
②deteriorated slurry in the drain-pipe
③the slurry leaks from bearing and is rotted
④ because of slow cleaning, the slurry in
hopper becomes deteriorated.

① replace the belt and adjust the
tightness.
②clean the drain-pipe or replace
③clean the inside parts of machine
and repair the bearing
④please see the manual above.
