5. MAINTENANCE AND CLEANING
The scale does not require any routine maintenance. However, we recommend checking the scale’s accuracy at
regular intervals. The regularity of these checks is dependent on the level of use and the state of the scale.
o We would recommend using alcohol based wipes or similar when cleaning the scale.
o Please do not use large amounts of water when cleaning the scale as this will cause damage to the scale’s
electronics, you should also refrain from using corrosive liquids or high pressure washers.
o Always disconnect the scale from the main power supply before cleaning.
