Oil filter change for City Transformer in Haifa

Oil filter change

The oil filter needs to be replaced if it is clogged, as indicated by an oil pressure drop in the system and a noticeable oil consumption increase. To remove the filter, unscrew the filler cap, unscrew the drain plug on the pallet, previously placing an empty container under it and dismantle the old filter. After the oil stops flowing into the container, tighten the drain plug, install a new filter, fill in fresh oil and tighten the filler cap.
