6.1 The scale should be flatly placed. Though the scale has good protection, it must 

be used under high non-vibration conduction. 

6.2 While weighing, place the load in the center of the platter as far as possible.   

6.3 Never use high corrosive solvents to clean it. 

6.4 Do not weight overload, when the weighing exceeds the Max. Ca9e, it 

will display" FULL ". 

6.5 Don't place load on the scale platter for long period of time. Never bump the 

platter with weighing load; otherwise the load cell would be damaged. 

6.6 Don't disassemble it without authorization. Non-authorized manufacturer or 

non-professional staff' can't fix it without permission; contact our sales agent in local 

area.
