6.0 Routine
6.1 Clean
Stop CM-100M3
Cut off the power before cleaning
Open the grinding chamber door
The rotor and sieve can be taken out for cleaning
Use alcohol and water to clean the rotor and bottom sieve, wipe dry with a dry cloth after
cleaning
The wear condition of the grinding kit should be checked regularly and replaced if necessary
Note：
⚫Do not use running water or any solvent to clean the instrument. Otherwise it may cause
shock or damage to the surface of the instrument. It is recommended to use a damp cloth
to clean the instrument.
⚫If necessary, the relevant grinding accessories can be removed and clean the instrument
with a long rush and industrial vacuum cleaner.
6.2 Safety Switch and Safety Inspections
When the instrument is in operation, it is forbidden to open the grinding chamber door. In case
the safety switch is invalid, it may cause personal injury or equipment damage.
Please check the instrument’s grinding chamber safety switch every half year:
Open the grinding chamber door and take out all grinding kits
Press“START”key and the instrument cannot be activated
Close grinding chamber door and press “START”, the instrument is activated
Note
Please contact MRC and inform the relative distributor if the instrument can still run
No.

Maintenance 6.3
In order to ensure the reliable operation of the CM-100M3, the following maintenance shall
be carried out daily after use
⚫The grinding kit, rotor and sieve should be wiped dry after cleaning and placed in a dry
and ventilated place. If the grinding kit has not been used for a long time, a layer of anti-
rust oil should be applied to it;
⚫The heavy metal-free grinding kit is made of special steel material, which is more likely to
rust. But this will not affect the normal use of the grinding kit;
⚫The rotor shaft may rust due to frequent contact with the sample. To avoid this, it should
be cleaned and wiped with a dry cloth each time after use. If the instrument is not in use
for a long time, it is recommended to apply a layer of anti-rust oil on the knife shaft.
6.4 Accessories
Please do not make any changes to the instrument accessories, and only use the accessories
!provided by MRC, otherwise the warranty will be invalid
6.5 Wear
Grinding sets are composed of rotor, bottom sieve which are consumables. Wear and
consumption are normal. The extent of the wear depends on the use frequency and the nature
of the sample.
The wear condition of the grinding kit should be checked regularly and replaced if necessary.
Grinding kits are not covered by the warranty.
6.6 Testing
⚫When grinding samples with high toughness, the feed size should be minimized as far as
possible;
⚫If the original sample size is large, two steps of grinding are recommended:
Firstly, use the sieve with a larger aperture to pre-pulverize;
Then use the required sieve aperture for secondary grinding.
