CAUTION 
The tweezers can scratch the bar. Exercise caution when 
using the tweezers to clean the bar. Avoid direct contact 
between the tweezers and the bar. Do not use excessive 
force when cleaning the bar. Otherwise it may bend. 
NOTE 
Mindray recommends the acid and alkaline detergents be 
used alternately for this purpose. For instance, if the acid 
detergent has been used for last maintenance, the alkaline 
detergent had better be used for this time. 
 
Use tweezers to pinch acid or alkaline detergent-soaked gauze, and then 
gently clean the exterior of the mixing bar until it is clean and smooth.
 
4
Use tweezers to pinch deionized water-soaked gauze to clean the mixing 
bar. 
5
After cleaning, gently pull the bar arm up and rotate the bar arm to move 
the bar to a position above the wash pool.
