MAINTENANCE AND GENERAL CARE
• Repairs and Servicing should only be carried out by authorised service
agents.
• There are no user serviceable parts in the weighing scale itself.
• The mains power adaptor contains 2 fuses, 1 internal that is not
accessible and 1 external user replaceable fuse. The fuse value is
T400mA and no other fuse value should be used.
• When the adaptor is plugged in to the mains supply a Green LED should
illuminate to indicate that the adaptor is functioning correctly. If the LED
does not illuminate then the external fuse should be checked by
competent personnel.
• There are no other user serviceable parts inside the mains adaptor.
• The weight indicator contains an internal rechargeable battery pack; this
should only be replaced by authorised service agents. Under normal
operating conditions the batteries should last for several years.
• We would recommend using alcohol based wipes or similar when cleaning
the scales.
• Please do not use large amounts of water when cleaning the scales as this
will cause damage to the scales electronics, you should also refrain from
using corrosive liquids or high pressure washers.
• Always disconnect the scales from the mains power supply before
cleaning.

*1 – These errors are normally caused by a serious fault on the
scales such as a faulty load cell or wiring. You should contact our
Service Department.
*2 – These errors are usually less serious and can be rectified by re-
calibration, however they can indicate an underlying problem with the
scales. Zero Range is set to 10% of Scale Capacity E.g. Capacity
200.0kg = Zero Range +/-20.0kg
