Experience has taught us that theintegrated weighing system continues to function even if the chassis was damagedby overloading.General rules: As the steering wheels are mounted at the front, it is better to pull rather thanpush the manual pallet truck. If the lifting device is not used, the manual lever should be left in centreposition. This prolongs the life span of the seals. To prevent damages to the electronic system and weighing cells it isnecessary that welding work on the entire weighing system is carried outexclusively by technical specialists. The bearings of the wheels (with the exception of polyurethane) as well as thejoints in the load roller section should be regularly cleaned and greased.8.3 DisposalDisposal of packaging and appliance must be carried out by operator according tovalid national or regional law of the location where the appliance is used.9 Error messagesThe battery symbol flashes: The battery is almost emptyand must be replaced.Low bat Critical error message:The battery is almost empty.Replace it immediately.Otherwise the weighing system will turn off.
